Abstract
A remote controlled apparatus (4), e.g., a remote controlled toy, for remote control from a remote control unit, e.g., a pocket torch (2). The apparatus is characterized in that it is adapted to respond to a sequence of light pulses which have a frequency of repetition that is lower than the maximum frequency which a human being can produce manually, e.g., by alternately turning the torch on and off. In a special embodiment, after a received sequence of light pulses, the apparatus is adapted to emit an acoustic acceptance signal by means of sound generator (15).
Description
A remote controlled toy The present invention relates to a remote controlled toy element for remote control by means of signals from a re-inote control unit, said toy element comprising a sensor which can detect the signals, and at least one unit which is controlled by a microprocessor in response to a pro-gram which is executed by the microprocessor, said pro-gram comprising program steps.
Such toy elements are widely used and are known e.g. from the product ROBOTICS INVENTION SYSTEM from LEGO MIND-STORMS, which is a toy that can be programmed by means of a computer to perform conditional as well as uncondi-tional actions.
Such toy elements are unique in that programs or other forms of instructions are transferred to the toy by means of a form of communications protocol. Typically, the com-munications protocol will be adapted to transfer data to the toy in the fastest possible and simultaneously most error-free manner to achieve a good and fast response.
It is a problem with such a toy, however, that the full play potential is not utilized fully.
Accordingly, an object is to provide new play possibili-ties with an electronic toy.
This is achieved when the toy element mentioned in the opening paragraph is characterized in that the toy ele-ment is adapted to record pulse patterns containing pulses which have flanks with intervals that are longer than the response time of a human being, and to control the unit in various ways by selecting a program step in response to a recorded pulse pattern.
SUBSTITUTE SHEET (RULE 26) It is ensured hereby that the toy element can be remote controlled by sound or particularly by light. Remote control by light takes place in that a user signals with e.g. an ordinary hand-held lamp which is driven by batteries or by the mains. The signalling takes place in that the user manually turns the lamp on and off and thereby produces pulses of visible light with a predetermined sequence of short and long pulses and intervals. The signalling may also take place by means of sound pulses, which may e.g. be produced in that the user claps his hands or whistles or sings a specific sequence of short and long pulses and intervals.
According to an aspect of the invention, there is provided a remote controlled toy element for remote control by means of signals from a remote control unit, said toy element comprising a sensor which is coupled to a microprocessor for detection of the signals, at least one unit which is controlled by the microprocessor to control the at least one unit in response to a program which is executed by the microprocessor, said program comprising program steps which when executed make the microprocessor responsive to the signals, wherein the toy element is arranged to: record a pulse pattern with pulses which have flanks, and control a predetermined unit of the at least one units by selecting a program step in dependence of how flanks, with mutual intervals that are longer than 100 milliseconds, occurred temporally in the recorded pulse pattern.
There is also provided a remote controlled toy element with a receiver for reception of instructions for programming the toy element as well as means for execution of received instructions, wherein the toy element has a 2a transmitter for transmission of instructions to a second toy element.
Embodiments of the invention will now be described with reference to the drawing, in which fig. 1 shows a block diagram of a remote controlled toy element for remote control by means of signals from a remote control unit and for control of units;
fig. 2 shows a flow chart for a program for selecting a subset of program steps from a set of program steps in response to an operation selection;

Fig. 1 shows a block diagram for a remote controlled toy element for remote control by means of signals from a re-mote control unit and for control of units. A user 101, e.g. a playing child, can operate a signal generator, e.g. a pocket torch 102. The pocket torch can be operated by alternately turning the torch on and off or by moving the cone of light of the torch. The cone of light may be directed toward a light detector 103. The light detector may be positioned behind a protecting light permeable plate in a toy element 104. The toy element may e.g. be a building element which can be connected with other build-ing elements of the same or another type. The detector 103 can emit a signal in response to the light which it receives. The signal may be an analogue signal which de-pends on the light intensity which falls on the light de-tector or merely be a simple on/off signal. The toy ele-ment 104 comprises a microprocessor 105 which can perform one or more programs stored in the memory 110. The micro-processor 105 is connected to a number of units for transmitting and receiving signals. A first unit 109 can receive signals on external mechanical impacts e.g. from a switch 112. A second unit 108 can emit light signals via a lamp or light diode 113. A third unit 107 can con-trol a motor 114. A fourth unit 106 can emit sound sig-nals via a sound generator 115 e.g. a loudspeaker or a piezoelectric element. Moreover, the microprocessor 105 can control an LCD display 116. The switch 111 can be SUBSTITUTE SHEET (RULE 26) used for selecting a state of the microprocessor 105 so that a specific subset of program steps can be selected from a set of program steps.
It is thus possible to combine the above-mentioned ele-ments/units so that the toy element inay be incorporated in a structure such as e.g. a car or another vehicle or a movable figure, the structure being composed of elements in a construction toy set.
Fig. 2 shows a flow chart for a program for selecting a subset of program steps from a set of program steps in response to an operation selection. The operation selec-tion can e.g. take place by operating the switch 111. The flow chart starts in step 200. Then a subset of program steps is selected. A subset of program steps is also called a rule. In 201, rule R is selected from a collec-tion of predetermined rules Rl-R7 in the form of rule based programs stored in the memory 110. It is decided in step 202 whether the selected rule is rule R=R1. If this is the case (yes), the rule based program Rl is executed in step 203. Alternatively (no), it is checked whether rule R=R2 was selected. Correspondingly, it is decided in steps 204, 206 and 208 whether the selected rule is rule 2, 3 or 7, and respective rule based programs are exe-cuted in steps 205, 207 or 209. It is thus possible to select one of several predetermined rules. These rules may e.g. be determined by the manufacturer of the toy element.
However, it will also be possible to store user defined rules by coinbining the predetermined rules. This will be mentioned below in connection with the description of fig. 7.
SUBSTITUTE SHEET (RULE 26) Fig. 3 shows a flow chart for a program for controlling a unit in various ways by selecting a program step in re-sponse to a recorded pulse pattern. An audio/visual sig-nal may be emitted in response to the recorded pulse pat-5 tern as a receipt for the reception of the pulse pattern.
The pulse pattern may be generated by flashing a pocket torch.
Step 301 corresponds to step 208 in fig. 2. In step 302, a pulse pattern is detected, consisting of e.g. a pulse of 1 second's duration, a pause of 1 second, a pulse of 1 second's duration, a pause of 1 second's duration, and a pulse of 3 seconds' duration.
It is decided in step 302 whether the pulse pattern is a known pulse pattern (e.g. stored together with other pulse patterns in the memory 110). If the pulse pattern is a known pattern S1 (yes), an audio or visual signal L1 recognizable by the user is played in step 305. An audio signal may e.g. be played by means of a piezoelectric element. The user can hereby receive a receipt of recog-nition of the command. This may be part of the play with the toy element. The user may be rewarded in step 307 in that the toy element performs a given action by executing a sequence of commands in the microprocessor 105.
Alternatively, if the light sequence was not recognized in step 303, another sound sequence L2 may be played in step 304. Subsequently, the toy element may perform an action corresponding to a wrong answer.
Examples of possible functions of a number of rule based programs R1-R7 are given below (rule 1, rule 2, rule 3, rule 4, rule 5, rule 6 and rule 7).
Rule 1:
SUBSTITUTE SHEET (RULE 26) 1) A pause of 1 second.
2) A sound sequence (start sound) is played.
3) A pause of 0.5 second.
4) A sound sequence (backward sound) is played.
5) The motor runs backwards for 5 seconds.
6) The motor stops.

Examples of possible functions of a number of rule based programs R1-R7 are given below (rule 1, rule 2, rule 3, rule 4, rule 5, rule 6 and rule 7).
Rule 1:
SUBSTITUTE SHEET (RULE 26) 1) A pause of 1 second.
2) A sound sequence (start sound) is played.
3) A pause of 0.5 second.
4) A sound sequence (backward sound) is played.
5) The motor runs backwards for 5 seconds.
6) The motor stops.
7) Points 3-6 are repeated twice (3 times in all).
8) The rule is stopped.
Rule 2:
1) A pause of 1 second.
2) A sound sequence (start sound) is played.
3) A pause of 0.5 second.
4) A sound sequence (backward sound) is played.
5) The motor runs backwards for 5 seconds.
Rule 2:
1) A pause of 1 second.
2) A sound sequence (start sound) is played.
3) A pause of 0.5 second.
4) A sound sequence (backward sound) is played.
5) The motor runs backwards for 5 seconds.
9) The motor stops.
6) A pause of 0.5 second.
7) A sound sequence (forward sound) is played.
8) The motor runs forwards for 5 seconds.
6) A pause of 0.5 second.
7) A sound sequence (forward sound) is played.
8) The motor runs forwards for 5 seconds.
10) The motor stops.
11) Points 3-10 are repeated twice (3 times in all).
12) The rule is stopped.
Rule 3:
1) A pause of 1 second.
2) A sound sequence (calibrate sound) is played.
3) A sound sequence (start sound) is played.
4) A sound sequence (backward sound) is played.
5) The motor runs backwards for max. 7 seconds.
6) If light is detected before the 7 seconds have elapsed (point 5):
- The motor stops.
- Forward sound sequence is played.
- The motor runs forwards as long as light is SUBSTITUTE SHEET (RULE 26) detected.
If light disappears:
i. The motor stops after 0.5 second.
ii. If the light comes back within 2 seconds, the motor starts again.
iii. If the light is out for 2 seconds, then the motor remains turned off.
7) Points 4-6 are repeated as long as light is detected within the 7 seconds and until 3 attempts without light have been made.
8) The motor stops.
9) The rule stops.
Example of the user's experience: The model is con-structed such that when the model drives backwards the model turns, and when it drives forwards, it drives straight ahead. The rule therefore gives a search light function - when the user throws light on the model, the model drives forwards toward the user.
Rule 4:
1) A pause of 1 second.
2) Motor direction is set for forwards.
3) A sound sequence (calibrate sound) is played.
4) A sound sequence (start sound) is played.
5) When light is detected:
- The motor runs.
6) When dark is detected:
- The motor stops.
7) When 2 flashes are detected:
- The motor direction is changed either from for-wards to reverse or from reverse to forwards.
- A sound sequence is played in accordance with the direction of the motor.
8) The rule is stopped 15 minutes after the last light SUBSTITUTE SHEET (RULE 26) was detected.
Example of the user's experience: The user experiences a remote control. The user can run the motor by constantly throwing light on the model, and change the motor direc-tion by flashing to the model.
Rule 5:
1) A pause of 1 second.
2) A sound sequence (calibrate sound) is played.
3) A sound sequence (start sound) is played.
4) When a flash is detected:
- A sound is played.
- If the motor is off, it is turned on.
- If the motor is on, the speed is increased by one step.
5) If no light is detected:
- If the speed is greater than step 0, the speed is reduced by one step.
- If the speed is step 0, the motor is stopped.
6) The rule stops 15 minutes after the last flash.
Example of the user's experience: The user experiences a form of "keep alive" function. The more and faster flashes, the faster the model runs and the more sounds it plays. If the user does not flash to it, the model "dies".
Rule 6:
1) A pause of 1 second.
2) Motor direction is set for reverse.
3) A sound sequence (calibrate sound) is played.
4) A sound sequence (start sound) is played.
5) When a change in the light level takes place:
SUBSTITUTE SHEET (RULE 26) - The alarm sound sequence is played.
- The motor runs for 1 second.
- The motor direction is changed.
- The above 3 points are repeated 6 times.
6) The rule is stopped.
Example of the user's experience: The user experiences an alarm function where the user e.g. places a pocket torch which throws light on the model. Then the rule is started, when the light beam from the pocket torch is broken, the alarm sound is played and the motor runs.
Rule 7:
1) A pause of 1 second.
2) A sound sequence (calibrate sound) is played.
3) A sound sequence (start sound) is played.
4) A pause of 1.5 seconds.
5) A long or short tone is played (random).
6) Points 4 and 5 are repeated 2 to 4 times (random). 3 to 5 times in all.
Then the user must send long and short flashes to the model in accordance with the tones.
7) Check flash length:
- Short flash must be less than 0.5 second.
- Long flash must be between 0.5 and 2 seconds.
8) If the length and number of flashes are correct:
- Play sound sequence (correct sound) - The motor runs forwards for 300 milliseconds.
- The rule stops.
9) If the length and number of flashes are wrong:
- Play sound sequence.
- The motor runs backwards for 300 milliseconds.
- Repeat points 4 - 7 2 times more and until success.
- If wrong flashes have been given 3 times, a SUBSTITUTE SHEET (RULE 26) sound sequence (tease sound) is played.
- The rule stops.
Example of the user's experience: 3 - 5 tones are played 5 for the user. The tones are played in either a short ver-sion or a long version. When the user has heard the tones, the user must flash back the length and the number of the tones in the form of light. If the user does this correctly, a success sound is obtained, and the motor 10 runs forwards briefly. If the user does not flash the correct length or number, a sound is played and the motor runs backwards briefly. The user gets 2 more attempts for performing the task (3 attempts in all). If the user is not successful in the 3 attempts, a tease sound is played.
In a preferred embodiment, a given recognizable pulse pattern (Sl-S7) can be related to a given sound sequence (Ll-L7) so that the user may be informed of the pulse pattern which has been received, and e.g. of the rule or command that will be executed by the microprocessor.
Fig. 4 shows examples of recorded pulse patterns Ml, M2 and M3. The pulse patterns may be selected in many dif-ferent ways, provided that they satisfy the condition that characteristics in the form of the duration of two successive flanks for the patterns are generated so that the duration is greater than the human response time. Two successive flanks may be a positive flank followed by a negative flank or two successive positive flanks.
The pulse pattern Ml comprises a positive flank and a negative flank.
SUBSTITUTE SHEET (RULE 26) The pulse pattern M2 comprises two successive pulses of a relatively short duration, e.g. 400 milliseconds sepa-rated by a period of e.g. 700 milliseconds.
The pulse pattern M3 comprises a pulse of a relatively long duration of e.g. 20 seconds.
These pulse patterns may cause a response from the toy element, e.g. as described above.
Fig. 5 shows an example of an emitted pulse pattern and an associated recorded pulse pattern. This may be an example of a pulse pattern in connection with rule 7 de-scribed above. The pulse pattern to the left can indicate playing of two short tones followed by a long tone of du-rations of tl and t2, respectively. After playing of the tones, the toy element expects that the user tries to imitate the pattern by generating light pulses with a pattern, that is two short pulses followed by a long pulse.
As it may be difficult for the user, who tries to imitate the pattern, to find the precise length of the emitted pulses and to generate pulses of the same length, it is accepted that the pulses may deviate by a specified de-viation d.
Fig. 6 shows first and second toy elements, where the first toy element can transfer data to the second toy element. The first toy element 601 comprises a microproc-essor 607, a I/0 module 610, a memory 609 and a user in-terface 608. The toy element 601 moreover comprises a two-way communications unit 606 for communication with an infrared transmitter/receiver 605 or for communication by means of a light source/light detector 604 which can emit and detect visible light.
SUBSTITUTE SHEET (RULE 26) Correspondingly, the second toy element 602 comprises a microprocessor 614, a I/0 module 615 and a memory 616.
The toy element 602 moreover comprises a communications unit 613 for communication via an infrared transmit-ter/receiver 612 or for communication by means of a light source/light detector 611 which can emit and detect visible light.
In a preferred embodiment of the invention, the first toy element can both transmit and receive data, while the second toy element can only receive data.
Data can be transferred as visible light via a light guide 603. Alternatively, data may be transferred as in-frared light 617 and 618. Data may be in the form of codes that indicate a specific instruction and associated parameters which can be interpreted by the microproces-sors 607 and/or 614. Alternatively, data may be in the form of codes which refer to a subprogram or a rule stored in the memory 616.
The I/0 modules 610 and 615 may be connected to elec-tronic units (e.g. motors) for control of these. The I/0 modules 610 and 615 may also be connected to electronic sensors so that the units may be controlled in response to detected signals.
In a preferred embodiment, the fibre 603 is adapted such that part of the visible light transmitted by it escapes from the fibre. It is hereby possible for a user - di-rectly - to watch the transmission. The user can e.g. see when the communication begins and stops.
The light through the fibre can transfer data with a given data transmission frequency as changes in the light SUBSTITUTE SHEET (RULE 26) level in the fibre. Data may be transmitted such that it is possible for the user to observe individual light level changes during a transmission (that is at a suit-ably low data transmission frequency) or merely by seeing whether the transmission is going on (that is with a suitably high data transmission frequency).
Generally, it is undesirable that part of the light to be transmitted through the fibre escapes from the fibre. But in connection with communication between two toy elements it is a desired effect, since it is then possible to watch the communication in a very intuitive manner.
It is known to a skilled person how to ensure that part of the light escapes from the fibre. It can e.g. be done by imparting impurities to the sheath of the fibre or by making mechanical notches or patterns in the fibre. The part of the light which is to escape from the fibre may also be controlled by controlling the ratio of the re-fractive index of a core to that of a sheath of a light guide.
Fig. 7 shows a flow chart for the storage of program steps. Step 701 corresponds to step 211. The flow chart shows how a user can store own rules transferred from an external unit for e.g. another toy element, as stated above, or from a personal computer. In an embodiment, just references to the rules stored in the toy element are transferred. This reduces the necessary bandwidth for communication between the toy elements. It is checked in step 702 whether download signals are received from ex-ternal units. If this is the case, it is checked in step 703 whether the download signals are valid. If the sig-nals are not valid (no), a sound indicating an error is played in step 704. If the signals are valid (yes), it is checked whether the signals are to be interpreted as com-SUBSTITUTE SHEET (RULE 26) mands which are to be executed at once (execute), or whether the signals are to be interpreted as commands which are to be stored with a view to subsequent execu-tion (save). If the commands are to be executed at once, this is done in step 706, and then the program returns to step 702. If the commands are to be stored, a recognition sound is played in step 707 and the command is stored as a program step in step 708 in the storage 709.
An example of a command to be carried out at once may be that the commands in the storage 709 are to be executed.
In an alternative embodiment, the user's own rules may be formed by making a combination of existing rules without using an external unit.
Fig. 8 shows a block diagram for a first toy element which can transfer data to a second toy element. The toy element 801 comprises a plurality of electronic means for programming the toy element so that it can affect elec-tronic units (e.g. motors) in response to signals picked up from various electronic sensors (e.g. electrical switches).
The toy element may hereby be caused to perform sophisti-cated functions such as e.g. event-controlled movement, on condition that the toy element is combined with the electronic units/sensors in a suitable manner.
The toy element 801 comprises a microprocessor 802 which is connected to a plurality of units via a communications bus 803. The microprocessor 802 can receive data via the communications bus 803 from two A/D converters "A/D input #1" 105 and "A/D input #2" 806. The A/D converters can pick up discrete multibit signals or simple binary sig-SUBSTITUTE SHEET (RULE 26) nals. Furthermore, the A/D converters are adapted to de-tect passive values such as e.g. ohmic resistance.
The microprocessor 802 can control electronic units such 5 as e.g. an electric motor (not shown) via a set of termi-nals "PWM output #1" 807 and "PWM output #2" 808. In a preferred embodiment of the invention, the electronic units are controlled by a pulse width modulated signal.
10 Further, the toy element can emit sound signals or sound sequences by controlling a sound generator 809, e.g. a loudspeaker or piezoelectric unit.
The toy element can emit light signals via the light 15 source "VL output" 810. These light signals may be emit-ted by means of light-emitting diodes. The light-emitting diodes may e.g. be adapted to indicate various states for the toy element and the electronic units/sensors. The light signals may moreover be used as communications sig-nals for other toy elements of a corresponding type. The light signals may e.g. be used for transferring data to another toy element via a light guide.
The toy element can receive light signals via the light detector "VL input" 111. These light signals may be used inter alia for detecting the intensity of the light in the room in which the toy element is present. The light signals may alternatively be received via a light guide and represent data from another toy element or a personal computer. The same light detector may thus have a commu-nication function via a light guide as well as serve as a light sensor for detecting the intensity of the light in the room in which the toy element is present.
In a preferred embodiment, "VL input" 811 is adapted to selectively either communicate via a light guide, or al-SUBSTITUTE SHEET (RULE 26) ternatively to detect the intensity of the light in the room in which the toy element is present.
Via the infrared light detector "IR input/output" 812, the toy element can transfer data to other toy elements or receive data from other toy elements or e.g. a per-sonal computer.
The microprocessor 802 uses a communications protocol for receiving or transmitting data.
The display 804 and the keys "shift" 813, "run" 814, "se-lect" 815 and "start/interrupt" 816 constitute a user in-terface for operating/programming the toy element. In a preferred embodiment, the display is an LCD display that can show a plurality of specific icons or symbols. The appearance of the symbols on the display may be con-trolled individually, e.g. an icon may be visible, be in-visible and be caused to flash.
By affecting the keys, the toy element may be programmed at the same time as the display provides feedback to the user about the program which is being generated or exe-cuted. This will be described more fully below. As the user interface comprises a limited number of elements (that is a limited number of icons and keys), it is en-sured that a child who wants to play with the toy will quickly learn how to operate it.
The toy element also comprises a memory 817 in the form of RAM and ROM. The memory contains an operating system "OS" 818 for control of the basic functions of the micro-processor, a program control "PS" 819 capable of control-ling the execution of user-specified programs, a plural-ity of rules 820, each rule consisting of a plurality of SUBSTITUTE SHEET (RULE 26) specific instructions for the microprocessor, and a pro-gram 821 in RAM which utilizes the specific rules.
In a preferred embodiment, the toy element is based on a so-called single chip processor which comprises a plural-ity of inputs and outputs, a memory and a microprocessor in a single integrated circuit.
In a preferred embodiment, the toy element comprises light-emitting diodes which can indicate the direction of rotation of connected motors.
SUBSTITUTE SHEET (RULE 26)
Rule 3:
1) A pause of 1 second.
2) A sound sequence (calibrate sound) is played.
3) A sound sequence (start sound) is played.
4) A sound sequence (backward sound) is played.
5) The motor runs backwards for max. 7 seconds.
6) If light is detected before the 7 seconds have elapsed (point 5):
- The motor stops.
- Forward sound sequence is played.
- The motor runs forwards as long as light is SUBSTITUTE SHEET (RULE 26) detected.
If light disappears:
i. The motor stops after 0.5 second.
ii. If the light comes back within 2 seconds, the motor starts again.
iii. If the light is out for 2 seconds, then the motor remains turned off.
7) Points 4-6 are repeated as long as light is detected within the 7 seconds and until 3 attempts without light have been made.
8) The motor stops.
9) The rule stops.
Example of the user's experience: The model is con-structed such that when the model drives backwards the model turns, and when it drives forwards, it drives straight ahead. The rule therefore gives a search light function - when the user throws light on the model, the model drives forwards toward the user.
Rule 4:
1) A pause of 1 second.
2) Motor direction is set for forwards.
3) A sound sequence (calibrate sound) is played.
4) A sound sequence (start sound) is played.
5) When light is detected:
- The motor runs.
6) When dark is detected:
- The motor stops.
7) When 2 flashes are detected:
- The motor direction is changed either from for-wards to reverse or from reverse to forwards.
- A sound sequence is played in accordance with the direction of the motor.
8) The rule is stopped 15 minutes after the last light SUBSTITUTE SHEET (RULE 26) was detected.
Example of the user's experience: The user experiences a remote control. The user can run the motor by constantly throwing light on the model, and change the motor direc-tion by flashing to the model.
Rule 5:
1) A pause of 1 second.
2) A sound sequence (calibrate sound) is played.
3) A sound sequence (start sound) is played.
4) When a flash is detected:
- A sound is played.
- If the motor is off, it is turned on.
- If the motor is on, the speed is increased by one step.
5) If no light is detected:
- If the speed is greater than step 0, the speed is reduced by one step.
- If the speed is step 0, the motor is stopped.
6) The rule stops 15 minutes after the last flash.
Example of the user's experience: The user experiences a form of "keep alive" function. The more and faster flashes, the faster the model runs and the more sounds it plays. If the user does not flash to it, the model "dies".
Rule 6:
1) A pause of 1 second.
2) Motor direction is set for reverse.
3) A sound sequence (calibrate sound) is played.
4) A sound sequence (start sound) is played.
5) When a change in the light level takes place:
SUBSTITUTE SHEET (RULE 26) - The alarm sound sequence is played.
- The motor runs for 1 second.
- The motor direction is changed.
- The above 3 points are repeated 6 times.
6) The rule is stopped.
Example of the user's experience: The user experiences an alarm function where the user e.g. places a pocket torch which throws light on the model. Then the rule is started, when the light beam from the pocket torch is broken, the alarm sound is played and the motor runs.
Rule 7:
1) A pause of 1 second.
2) A sound sequence (calibrate sound) is played.
3) A sound sequence (start sound) is played.
4) A pause of 1.5 seconds.
5) A long or short tone is played (random).
6) Points 4 and 5 are repeated 2 to 4 times (random). 3 to 5 times in all.
Then the user must send long and short flashes to the model in accordance with the tones.
7) Check flash length:
- Short flash must be less than 0.5 second.
- Long flash must be between 0.5 and 2 seconds.
8) If the length and number of flashes are correct:
- Play sound sequence (correct sound) - The motor runs forwards for 300 milliseconds.
- The rule stops.
9) If the length and number of flashes are wrong:
- Play sound sequence.
- The motor runs backwards for 300 milliseconds.
- Repeat points 4 - 7 2 times more and until success.
- If wrong flashes have been given 3 times, a SUBSTITUTE SHEET (RULE 26) sound sequence (tease sound) is played.
- The rule stops.
Example of the user's experience: 3 - 5 tones are played 5 for the user. The tones are played in either a short ver-sion or a long version. When the user has heard the tones, the user must flash back the length and the number of the tones in the form of light. If the user does this correctly, a success sound is obtained, and the motor 10 runs forwards briefly. If the user does not flash the correct length or number, a sound is played and the motor runs backwards briefly. The user gets 2 more attempts for performing the task (3 attempts in all). If the user is not successful in the 3 attempts, a tease sound is played.
In a preferred embodiment, a given recognizable pulse pattern (Sl-S7) can be related to a given sound sequence (Ll-L7) so that the user may be informed of the pulse pattern which has been received, and e.g. of the rule or command that will be executed by the microprocessor.
Fig. 4 shows examples of recorded pulse patterns Ml, M2 and M3. The pulse patterns may be selected in many dif-ferent ways, provided that they satisfy the condition that characteristics in the form of the duration of two successive flanks for the patterns are generated so that the duration is greater than the human response time. Two successive flanks may be a positive flank followed by a negative flank or two successive positive flanks.
The pulse pattern Ml comprises a positive flank and a negative flank.
SUBSTITUTE SHEET (RULE 26) The pulse pattern M2 comprises two successive pulses of a relatively short duration, e.g. 400 milliseconds sepa-rated by a period of e.g. 700 milliseconds.
The pulse pattern M3 comprises a pulse of a relatively long duration of e.g. 20 seconds.
These pulse patterns may cause a response from the toy element, e.g. as described above.
Fig. 5 shows an example of an emitted pulse pattern and an associated recorded pulse pattern. This may be an example of a pulse pattern in connection with rule 7 de-scribed above. The pulse pattern to the left can indicate playing of two short tones followed by a long tone of du-rations of tl and t2, respectively. After playing of the tones, the toy element expects that the user tries to imitate the pattern by generating light pulses with a pattern, that is two short pulses followed by a long pulse.
As it may be difficult for the user, who tries to imitate the pattern, to find the precise length of the emitted pulses and to generate pulses of the same length, it is accepted that the pulses may deviate by a specified de-viation d.
Fig. 6 shows first and second toy elements, where the first toy element can transfer data to the second toy element. The first toy element 601 comprises a microproc-essor 607, a I/0 module 610, a memory 609 and a user in-terface 608. The toy element 601 moreover comprises a two-way communications unit 606 for communication with an infrared transmitter/receiver 605 or for communication by means of a light source/light detector 604 which can emit and detect visible light.
SUBSTITUTE SHEET (RULE 26) Correspondingly, the second toy element 602 comprises a microprocessor 614, a I/0 module 615 and a memory 616.
The toy element 602 moreover comprises a communications unit 613 for communication via an infrared transmit-ter/receiver 612 or for communication by means of a light source/light detector 611 which can emit and detect visible light.
In a preferred embodiment of the invention, the first toy element can both transmit and receive data, while the second toy element can only receive data.
Data can be transferred as visible light via a light guide 603. Alternatively, data may be transferred as in-frared light 617 and 618. Data may be in the form of codes that indicate a specific instruction and associated parameters which can be interpreted by the microproces-sors 607 and/or 614. Alternatively, data may be in the form of codes which refer to a subprogram or a rule stored in the memory 616.
The I/0 modules 610 and 615 may be connected to elec-tronic units (e.g. motors) for control of these. The I/0 modules 610 and 615 may also be connected to electronic sensors so that the units may be controlled in response to detected signals.
In a preferred embodiment, the fibre 603 is adapted such that part of the visible light transmitted by it escapes from the fibre. It is hereby possible for a user - di-rectly - to watch the transmission. The user can e.g. see when the communication begins and stops.
The light through the fibre can transfer data with a given data transmission frequency as changes in the light SUBSTITUTE SHEET (RULE 26) level in the fibre. Data may be transmitted such that it is possible for the user to observe individual light level changes during a transmission (that is at a suit-ably low data transmission frequency) or merely by seeing whether the transmission is going on (that is with a suitably high data transmission frequency).
Generally, it is undesirable that part of the light to be transmitted through the fibre escapes from the fibre. But in connection with communication between two toy elements it is a desired effect, since it is then possible to watch the communication in a very intuitive manner.
It is known to a skilled person how to ensure that part of the light escapes from the fibre. It can e.g. be done by imparting impurities to the sheath of the fibre or by making mechanical notches or patterns in the fibre. The part of the light which is to escape from the fibre may also be controlled by controlling the ratio of the re-fractive index of a core to that of a sheath of a light guide.
Fig. 7 shows a flow chart for the storage of program steps. Step 701 corresponds to step 211. The flow chart shows how a user can store own rules transferred from an external unit for e.g. another toy element, as stated above, or from a personal computer. In an embodiment, just references to the rules stored in the toy element are transferred. This reduces the necessary bandwidth for communication between the toy elements. It is checked in step 702 whether download signals are received from ex-ternal units. If this is the case, it is checked in step 703 whether the download signals are valid. If the sig-nals are not valid (no), a sound indicating an error is played in step 704. If the signals are valid (yes), it is checked whether the signals are to be interpreted as com-SUBSTITUTE SHEET (RULE 26) mands which are to be executed at once (execute), or whether the signals are to be interpreted as commands which are to be stored with a view to subsequent execu-tion (save). If the commands are to be executed at once, this is done in step 706, and then the program returns to step 702. If the commands are to be stored, a recognition sound is played in step 707 and the command is stored as a program step in step 708 in the storage 709.
An example of a command to be carried out at once may be that the commands in the storage 709 are to be executed.
In an alternative embodiment, the user's own rules may be formed by making a combination of existing rules without using an external unit.
