Abstract

A system has an electronic key that transmits a coded signal and at least one tool or other device that can receive that signal. The coded signal is compared to a coded signal stored in the tool or other device. If the coded signal authenticates the stored signal, the tool is enabled or disabled for a specified amount of time. An on/off switch then enables the user of the tool to turn the tool or other device on and off during the specified amount of time. After the specified amount of time, the tool is disabled so that the tool or other device can no longer be used. Disabling the tool may be delayed if the tool or other device is in use. The tool or other device may also contain a unique identification code that can be read by an interrogating device to identify the tool or other device.

FIELD

The specification relates to the field of locks.

BACKGROUND

The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions.
This specification relates to a device that is remotely enabled and disabled. In particular, it relates to a device that is unlocked or locked remotely by means of an electronic key for a specified period of time, after which the device is automatically disabled. In this specification the phrase “predetermined period of time” may be substituted for the phrase “specified period of time.”
Easily carried, but expensive devices, such as digital cameras, video cameras, laptop computers, electronic instruments, and power tools, are very tempting to thieves. Currently, there is no effective, easy-to-use method of protecting such devices from theft. For example, while cell phones have a built-in electronic combination lock that prevents calls when activated, virtually no one uses it, because the procedure for activating and deactivating it is cumbersome and time-consuming.
In addition to thieves, devices may also be vulnerable to use by unauthorized persons, such as people who have not been trained to use the device properly or small children. For example, a child who thinks he can use the family's lawn mower, hedge trimmer, or table saw without training may inflict serious bodily injury to himself or others or damage property. Smaller tools can be locked away to prevent unauthorized usage, that may not be possible for larger tools.
It is common practice to place unique identification, such as an alphanumeric serial number, on devices so that if a device is stolen and recovered it can be identified and claimed. The owner of a device can also keep a record of the serial number of the device or register it with its manufacturer. However, identification can be removed or adulterated, and registration requires the manufacturer to maintain a list that links the owner's name to that serial number. It is both time consuming and difficult to find rightful owners of stolen property and, unless the property has a high value, the cost of recovering it may exceed its value.
Previous inventions, such as U.S. Pat. No. 6,005,489, have tried to eliminate battery operated tool theft from a predetermined and fixed work area by using a fixed transmitter that sent out an enable code to all the tools within signal range. When a battery is inserted into the tool, the tool is enabled until the battery is either drained or removed. Although that invention may operate successfully for a fixed work area, it is not intended to be a solution that could be applied to a wide range of different devices.
German patent DE10630766/US2004/0108120A1 implemented a remote keyless entry (RKE) system for tools. This approach is most commonly used as a method of locking and unlocking a passenger vehicle by means of a small electronic transmitter. As soon as the tool is unpowered, it would need to be reauthorized in order to function. In an industrial construction site, this simply isn't an acceptable solution as it requires the operator to carry the key with him and it provides more of an effort rather than a value, analogous to the cell phone example cited hereinabove. It lacks the needed utility to be acceptable to users.
Canadian patent CA02283552 tried to address the problem of portable tool theft by putting a keypad and an LCD display on the tool. The owner inserts a particular unlock code on the keypad and the tool functions until the power is removed. Again, this is not a practical solution as tools receive rough handling and a keypad and display simply would not last.

SUMMARY OF THE INVENTION

In an embodiment, a device that can be enabled or disabled for a specified period of time by means of an electronic key is provided.
A coded signal is transmitted from the electronic key to a receiver within the device and, if the code is authenticated, the device is enabled and can be operated or disabled; unauthorized codes may be ignored or logged for security purposes.
Once enabled, the device will operate for only the specified time period or until a disable signal is received. The enabled time period could be set by the manufacturer or operator of the device. After the expiration of the time period, the device could not be operated without re-enabling it by means of the electronic key.
If the device has a manually operable on-off switch, such as on a digital camera, the user can turn the device on and off as needed without affecting the timing circuit.
If the enabled time period concludes while the user is in the middle of an operation, the disabling of the device can be delayed. This permits a digital camera to complete the processing of an image into memory or a tool in the middle of drilling a hole to complete the task.
If the device is stolen, it would have little value since it will not operate. The lack of an electronic key to enable the device would be a sure sign that it was stolen and acts as a deterrent to both the thief and potential buyer.
Even if the power source is removed, the device could retain its enabled state for a specified duration. This permits moving an AC powered device, changing the battery, or other user activity.
If the use of the tool is completed before the disable time period is reached, the user can manually disable the tool by sending a disable signal via the electronic key. The electronic key could be part of other electronics such as a cell phone or computer. The enabled or disabled status of the tool can optionally be presented audibly and/or visually such as through the use of a display, LED(s), or a speaker on the tool. For example, a green-lit LED could indicate an enabled status while a blinking red LED could indicate 15 minutes left before the tool is disabled and an unlit LED could indicate a disabled status. A series of informational or warning beeps could also be used to convey the information.
The tool control circuit would contain a method of authenticating the coded signal received from the electronic key thus permitting only the correct authenticated signal to activate the tool. This will reduce theft since stealing the tool without possessing the correct electronic key will make the item inoperable and valueless and readily identifiable as stolen.
The control circuit in the tool may contain a unique identification code and have a means of communicating that identification code to an authorized identification tool, which could be part of the electronic key. This permits the identification of the tool's owner so that it can be returned if it is lost or stolen. Also, in an embodiment, the tool may be located and identified by reading the identifier stored in the tool. In an embodiment, there may be two identification codes stored in the control circuit. One of the two identification codes may be used to authenticate an authorized user (and used to determine whether to grant access to an operator requesting to use the tool) and a second identification code may be used to identify the tool to an interrogating device (a separate device from the tool that is reader for reading information from the tool) and thereby determine the owner of the tool (e.g., to determine whether the tool is stolen) or used for other purposes such as identifying the software version.
The tool according to the present invention will also prevent unauthorized users from operating the tool even when it has not been stolen. This is the most likely case with children or work environments where many tools may be accessible but where restricted operation is needed.
The tool may include an optional electronic combination lock so that, should the user forget his electronic key, he can enter and enable the tool by entering a code on the combination lock with a sequence of key presses on a series of switches rather than a traditional keypad. The results can be shown on a visual indicator, such as a display. With the correct activation code, the tool unlocks as if an enabling signal from the electronic key was received. After a successful key press activation sequence, the enabling key press activation sequence could remain unchanged or be modified based on security requirements. There are many electronic combination lock implementation options to suit the particular tool design requirements.
In addition to controlling the enabling and disabling of a tool, the timing circuit could have the means to optionally control the operation of the tool based on the date and time of day rather than simply a set time duration from an activation sequence. For example, an authorized user can program a tool to activate at 8 AM and deactivate at 6 PM. This can be accomplished prior to the time of use to add flexibility.
The electronic key could be reconfigured to operate multiple electronically controlled tools in different locations. This reconfiguration would permit one operator to control a number of tools with the use of a single electronic key, rather than having to use multiple individual electronic keys.
The reconfiguration of an electronic key is possible either by ordering the desired combination in a new electronic key from the manufacturer or by reconfiguring the key by logging into a secure database containing all of the key information via a network and specifying the specific tool that a particular electronic key would control. Optionally, the electronic key function could be combined with other electronic keys, such as an automobile electronic key or smart cards, in a single key.
An alternative to wireless communications would include a means of tool control via a wired connection. Communications could be transmitted via AC power wiring permitting the control operator to set the parameters in the tool.
With the development and standardization of ad hoc wireless networking now taking place, the tool could optionally have a means of communication with such a network. These new network topologies, such as Star or Mesh and combinations thereof, have no central orchestrating device. Instead, each network node has the means of identifying itself and acting as a relay point for other network nodes. This means of communication permits the tool to fix its location within such networks and allow for control and reprogramming of its function by remote authorized users.

DESCRIPTION OF EXAMPLES OF EMBODIMENTS

Although various embodiments of the invention may have been motivated by various deficiencies with the prior art, which may be discussed or alluded to in one or more places in the specification, the embodiments of the invention do not necessarily address any of these deficiencies. In other words, different embodiments of the invention may address different deficiencies that may be discussed in the specification. Some embodiments may only partially address some deficiencies or just one deficiency that may be discussed in the specification, and some embodiments may not address any of these deficiencies.
Referring to FIG. 1, a device 1 according to this invention comprises tool 2 and remote wireless electronic key 3 that can communicate with tool 2. Tool 2, for example, may be a power tool, such as a drill or saw, a lawn mower, a digital camera, computer, digital music player, video cameras, digital projectors, video game player, cell phone (wireless communication devices), portable transaction authentication devices (smart cards, payment cards, smart keys), or multimedia players. Tool 2 may be stationary or portable. When tool 2 is activated it can turn on an electric motor, gasoline engine, diesel engine, compressed air tool, chemical tool (e.g., a tool operated by firing blank ammunition), close or open an electric circuit, or another operation. Tool 2 may have an on/off function 4 that enables the operator of the tool to turn the tool on and off as it is needed. On/off function 4 will typically close an electric circuit or cause the circuit to go into a power saving mode, but may also turn the tool on and off by other means. On/off function may be any function or mechanism for turning on and off tool 2. For example, on/off function 4 may be a switch, button, software that turns tool 2 on and off or another on/off function. Tool 2 is further provided with a transceiver 5 that can send and receive coded wireless signals to and from electronic key 3. A control circuit 6 within tool 2 authenticates a coded electronic signal received from electronic key 3 to a coded signal stored within tool 2 and, if the coded signal is authenticated, closes locking switch 7. Locking switch 7 is in series with on/off function 4, so on/off function 4 is operable only if locking switch 7 is closed. There are many ways in which the authentications discussed in this specification may be performed. For example, a comparison may be made as to whether a code received in a signal matches or is the same as a stored code.
Electronic key 3 transmits a unique code sequence 8 (e.g., and identification code) to transceiver 5 in tool 2. Once the code sequence 8 is authenticated, timer 9 is activated for the desired time period. Control circuit 6 then turns on visual indicator 10, which gives a visual signal (an audible signal could also be used), indicating the command has been received. For example, a green LED (light emitting diode) may be blinked for a period of about 5 seconds. The sequence, duration, and annunciation of the signal may be determined by the manufacturer. Actuator 11 then turns on the application power control 12, thereby permitting the user to control the device's on/off function 4 until the enabled time period has expired. A power source 13, such as a battery or AC current, provides power for the electronics and the device.
At the end of the time period specified by timer 9, tool 2 turns on visual indicator 10 (or annunciates an audible signal), indicating the time period has expired, and deactivates actuator 11, which disables tool 2. Alternatively, a time period, say one minute, could be programmed into the tool 2 so that prior to the expiration of the time period specified by timer 9, the visual indicator 10 illuminates a visual signal (or annunciates an audible signal) to indicate there is only one minute remaining before tool 2 is deactivated. This might be advisable for safety, performance, or user convenience purposes.
A second alternative could be that at the expiration of the time period specified by timer 9, tool 2, is not deactivated as long as on/off function 4 is held in the “on” position by the user. This would allow the user to complete the task at hand and might be advisable for safety, performance, or user convenience purposes.
After tool 2 is enabled, and the user wishes to extend the operation cycle of tool 2 by reprogramming or resetting timer 9, the electronic key 3 can be used a second time. The operation of the tool 2 can be altered by having the electronic key 3 reprogram the operation of the tool 2. When tool 2 detects a unique sequence of electronic key signals from the electronic key signal 3, visual indicator 10 illuminates a visual signal (or annunciates an audible signal), for example flashing a green LED or providing a tone, to indicate it is now in a mode in which timer 9 can be reprogrammed. This time period for this mode would last for short time duration, such as about 30 seconds. This time period could be specified by the manufacturer of the tool based on market or customer requirements. If during this second time period, no further communication between electronic key 3 and control circuit 6 is received, tool 2 would exit this mode and resume normal operation for the remaining activation time period. If, during this time interval (e.g., a 30-second interval), the electronic key 3 to communicate with control circuit 6, the duration of timer 9 or other control function would be adjusted based on the command sent to control circuit 6. The second time interval would then be programmed or set by the control circuit 6. Alternatively, electronic key 3 could transmit a command to the control circuit 6 to terminate this mode immediately.
In addition to sending “enable” and “disable” commands to the tool, the electronic key 3 may contain switches for sending a variety of other commands to the unit. For example, during the assembly of the tool, a single unique identification code 8 may be inserted into tool 2. In this way, the tool can be interrogated as to its unique identification code or all the tools within an area can be interrogated to determine if any of them has a particular code in order to locate it. Stolen tools that have been recovered can be interrogated to obtain their identification code, which can then be used to identify the owner. Referring to FIG. 5, a PDA (Personal Digital Assistant) 38 is a handheld device 37 that combines computing, networking, communication and personal organizer features. Such an auxiliary device could possess the means of establishing authorized communications with the device 38 and retrieving the unique identification code. An auxiliary device could also perform the task via a network connection. In an embodiment, tool 2 may be remotely reprogrammed or reset via key 3 or another device.
FIG. 2 shows the process that occurs within tool 2 during operation of the device shown in FIG. 1. When tool 2 first receives power by, for example, being connected to a battery or AC outlet, the control system determines whether a time period is active (block 14). The existence of a valid time period indicates that the tool had been activated before power was lost, perhaps due to changing a battery or a disconnection.
If there is no active time period (block 14), the tool will be disabled (block 15), to ensure its inoperability. But if a time period is already active (block 14), the control system proceeds to check to see if a wireless signal is present (block 18). If a wireless signal is detected (block 18), the control circuit determines whether the wireless signal transmitted by the electronic key contains the unique identification code 8 which matches the tool's identification code (block 19). If a match is found, the control circuit determines whether a disable signal is present (block 20). If so, the device is disabled (block 15). If there is no authentication (block 19), the control transfers to where the time period is checked to see if it is still valid (block 16). If a disable signal is not present (block 20), an analysis is performed to determine whether an enable signal is present (block 21). If an enable signal (block 20), is present, the timer is reset, resulting in the activation of the tool (block 22).
If neither a disable signal (block 20), nor an enable signal (block 19), is present, a check is made to determine whether the time period has expired (block 16). If the time period has expired (block 16), an analysis is made to see if an in-use indication (block 17), is active. The in-use indication determines if the device is performing a function that should not be stopped. Device activation is delayed until the in-use indication is no longer active.
In FIG. 3, a mesh network has a variety of wireless access points 23, 24, 25, 26, 27, and 28 that are able to communicate among themselves. Some, but not all wireless access points have a connection to a network access point 29. The network access point 29 has access to a network, such as the internet 30. This architecture permits network access to systems that would not normally have network access.
A tool 31, which has the means of communicating with a wireless network, could have its operation remotely reprogrammed or reset, security code remotely changed, and location remotely identified. Location identification is possible by several means, such as by using global positioning system (GPS) electronic function or as each wireless access point 23, 24, 25, 26, 27, and 28 knows its physical location and can determine the general location of the transmitting device by using a variety of currently known frequency analysis and positioning techniques. Optionally remote reprogramming or resetting, remotely changing the security code, and/or remotely locating tool 2 may be performed via another communication system in addition to or instead of via a mesh network.
FIG. 4 is a flow diagram for a process for modifying the electronic key. The electronic key is capable of being reprogrammed or reset in order to control additional tools or change the operation of any tool, such as the time of activation or duration of activation.
Electronic key 32 is embedded or attached to a personal computer (PC) 33 by either wired or wireless means. PC 33 has a connection to a service provider's host computer 34 in order to communicate with the network. The PC 33 also runs a program that permits an authorized user to log in to remote secure database 36 via network connection 35, such as the internet. The PC program and its connection to secure database 36 provide the means of allowing the authorized user to make the needed changes to electronic key 32.
A manufacturer may want to offer the user the opportunity to combine a number of electronic keys 3 into a single physical key. This may be desirable by users who purchase a variety of devices utilizing the control function described herein. If a manufacturer so desired, an authorized operator could contact the manufacturer. The manufacturer could send the authorized operator a single electronic key 3 or multiple electronic keys 3 that would work with the specified devices. The authorized operator could optionally make the needed changes by accessing the secure database and reprogramming or resetting the electronic key or the device himself.
In other embodiments, the devices and methods of FIGS. 1-5 may not have all of the elements and/or steps listed above and/or may have other elements instead of or in addition to those listed. The steps of the methods may be performed in another than listed above.
Each embodiment disclosed herein may be used or otherwise combined with any of the other embodiments disclosed. Any element of any embodiment may be used in any embodiment.
Although the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the true spirit and scope of the invention. In addition, modifications may be made without departing from the essential teachings of the invention.

(E) a control circuit that compares the coded wireless signal received from the remote electronic key to a coded signal stored within the tool, wherein the coded signal stored is associated with the first unique identification code, wherein if the coded wireless signal received authenticates the coded signal stored, the locking switch is set to an on state, wherein the control circuit has a programmable mode that expires after a first time period or after receiving the signal to terminate the programmable mode

(1) wherein the control circuit includes at least

(a) storage for storing at least

(i) the coded signal associated with the first unique identifier for gaining access to the tool, and

(ii) another signal associated with the second unique identifier for identifying ownership of the tool, and

(b) a timer that is activated for a second time period if the coded wireless signal authenticates the signal stored, wherein

(i) the timer is settable such that at a start of a third time period prior to an end of the second time period the indicator indicates that the second time period will expire soon, and

(ii) the timer is for being reset to allow the second time period to be extended,

(2) wherein at an expiration of the time period the tool is not deactivated as long as the on/off switch is held in the on position by the operator,

(3) the control circuit is configured for performing a method including at least

(i) when the tool is initially powered, the control circuit determines whether the second time period expired,

(ii) if the second time period expired, the tool is disabled,

(iii) if second time period did not expire, the control circuit proceeds to determine if the coded wireless signal is present,

(iv) if the coded wireless signal is detected to be present, the control circuit determines whether the coded wireless signal contains the first unique identification code by at least checking whether the coded wireless signal matches the coded signal stored in the storage,

(v) if a match is found, the control circuit determines whether a disable signal is present,

(vi) if a disable signal is present, the control circuit disables the tool,

(vii) if no match is found, the second time period is checked to determine whether the second time period expired,

(viii) if the disable signal is not present, an analysis is performed to determine whether an enable signal is present,

(ix) if an enable signal is present, the timer is reprogrammed, causing the tool to be activated,

(x) if neither a disable signal nor an enable signal is present, a determination is made to determine whether the second time period has expired,

(xi) if the first time period has expired, an analysis is made to determine whether an in-use indication is active, wherein an active in-use indication indicates that the tool is currently performing a function that should not be stopped, and

(xii) if the in-use indication is active, deactivation of the tool is delayed until the in-use indication is no longer active,

(F) an indicator that gives an indication

(1) when the first time period begins,

(2) when the second time period begins, and

(3) when the first time period ends,

(G) an application power control, which when in an on state, permits the operator to control the tool via the on/off switch until the predetermined amount of time has expired when the power control is switched to an off state;

(H) an actuator that turns on the application power control,

(I) an electronic combination for entering a combination for accessing the tool, wherein the tool may be accessed by either the remote electronic key or the electronic combination, and

(J) a visual indication of an entry into the electronic combination; and

(III) a handheld device that is for

(A) interrogating the tool to find out the second unique identifier, and

(B) locating the tool based on the second unique identifier.

32. A method of remotely locking and unlocking a tool from an electronic key comprising

(A) storing a coded signal in said tool;

(B) sending a wireless coded signal from said electronic key to said tool;

(C) comparing said coded signal that was sent to said coded signal that was stored;

(D) if said coded signal that was sent is authenticated based on said stored coded signal that was stored, unlocking said tool for a predetermined period of time if an unlock signal was present or;

locking tool if a lock signal was present;

(E) after said predetermined amount of time, locking said tool; and,

(F) determining whether to delay performing (E) by at least,

if the time period has expired, performing an analysis to determine if an in-use indication is active, wherein an active in-use indication indicates that the tool is currently performing a function that should not be stopped, and

if the in-use indication is active, delaying a deactivation of the tool until the in-use flag is no longer active.
