Abstract
Description
- The present application is a continuation of and claims priority benefit under 35 U.S.C. § 120 from U.S. patent application Ser. No. 09/574,736, filed May 18, 2000, which is hereby incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The invention relates to remote control of computers.
- 2. Description of the Related Art
- In today's business world, personal computers are almost a necessity, and are commonly found in offices and employee workspaces. Generally, people turn their computer off when they leave the office after work in the evening. This is done to conserve energy, to address safety concerns common to all energized electrical appliances, and also in response to security concerns that someone other than the computer owner may gain access to sensitive business information. Thus, when most people arrive at the office in the morning, they must turn on their computer, wait for the system to boot up, and then launch some particular application program they will be using. This results in wasted time as the user sits and waits for the computer to complete the boot up process.
- Currently, no computer system is available that addresses this problem. Various types of remote control systems for computers have been described and marketed, but none are particularly suitable for resolving the above described problem. Many conventional remote computer controllers, wireless mice and keyboards, for example, have a very short communication range, and/or require a clear line of sight between the wireless transmitter in the device and the receiver in the computer. This makes them impractical for use by a worker until entering the office. There would therefore be minimal, if any, time savings involved with the use of these devices to control initiation of computer operation.
- Other remote control devices work over telephone connections. One example of such a system is provided by U.S. Pat. No. 5,596,628 to Jon Klein. These systems, however, require the initiation of a telephone connection with the computer to be controlled. This is not convenient for solving the above described problem. For these reasons, a convenient and simple to operate computer system with remote computer power control is needed in the art.
- The invention includes remotely controllable computer systems, methods of remote computer control, and devices for the remote control of computers. In one embodiment, the invention comprises a remote controlled computer system, including a computer comprising a wireless receiver and a hand-held controller comprising a wireless transmitter. The hand-held controller is configured to send a signal to the wireless receiver upon user actuation, and the computer is configured to perform a power on sequence and to launch a user-defined application program in response to receiving the signal.
- In another embodiment the invention comprises a method of remotely controlling a computer comprising transmitting a signal from a hand-held controller to the computer, and in response thereto, placing the computer in an on state and launching a user specified application program.
- One embodiment of a remote control device for a personal computer comprises a hand-held housing containing wireless signal transmission circuitry for communicating with wireless signal receiving circuitry in the personal computer. The housing comprises an attachment device for connecting the remote control device to a key ring, purse handle, or other commonly carried personal item. In another embodiment, a remote control device for a personal computer comprises a hand-held housing containing wireless signal transmission circuitry for communicating with wireless signal receiving circuitry in the personal computer and at least one user actuated control operative to initiate wireless signal transmission of a command to perform a power up sequence and launch a selected application program.
-
FIG. 1 is an overall perspective view of a hand-held computer controller in wireless communication with a personal computer according to one embodiment of the invention. -
FIG. 2 is flow chart illustrating steps performed by a computer in response to received control signals according to one embodiment of the invention. -
FIG. 3 is a block diagram of a computer system configured to receive and interpret control signals according to one embodiment of the invention. - Embodiments of the invention will now be described with reference to the accompanying Figures, wherein like numerals refer to like elements throughout. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain specific embodiments of the invention. Furthermore, embodiments of the invention may include several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the inventions herein described.
- Referring now to
FIG. 1 , a computer system in accordance with one embodiment of the invention comprises acontroller 20. Thecontroller 20 is advantageously small enough to fit comfortably in a person's hand as well as in a pocket, purse, automobile glove compartment, or the like. In one embodiment, thecontroller 20 comprises anattachment device 22. Theattachment device 22 may be a suitably sized hole, a wire loop or ring, or other facility for attaching thecontroller 20 to a key ring, purse handle, or other commonly carried personal item. - The
controller 20 also incorporates internal wireless transmission circuitry and an antenna (not shown) for wireless communication with acomputer 24 that incorporates anantenna 26 and a wireless receiver. These aspects of thecomputer 24 will be described in more detail below with reference toFIG. 3 . Using awireless link 28, thecontroller 20 sends commands to thecomputer 24. In one embodiment, the commands issued by thecontroller 20 are operative to place the computer in the on state and optionally to also launch a user specified application program such as a word processor, spreadsheet, web browser, CAD and CAE programs, etc. - As shown in
FIG. 1 , one embodiment of thecontroller 20 has three user actuated push buttons. Afirst button 30 may initiate onlycomputer 24 power up, but not launch any specific application programs. Asecond button 32 may initiate both power up and the launch of a first user defined application program. Athird button 34 may initiate both power up and the launch of a second user defined application program. Thus, the user may have a choice of several different remote control operations. This embodiment may be used to eliminate time wasted by computer users while waiting for their computer to boot up and load a desired application program. In a business or office environment, for example, a computer user may prefer to have their office computer on and running the moment they arrive at the office. In this embodiment, an advantageous range for thecommunication link 28 may be between approximately 200 and 500 feet. With this range, as the user is heading toward the office, they can press abutton controller 20, thereby initiating either only power up, or also power up plus the launch of a desired application. When they arrive at the office door a few minutes later, the computer is ready and waiting for them. - The construction of wireless transmitter and receiver circuitry suitable for implementing the
wireless link 28 is well known and will not be described in detail herein. This technology is used in applications such as garage door openers, keyless entry systems for automobiles, as well as other currently available commercial applications, and a wide variety of specific designs could be used in thecontroller 20 andcomputer 24 without altering the character of the system. The 200 to 500 foot range may be advantageous in that it is far enough to generally provide two or more minutes between initiation of power up and arrival of the user at thecomputer 24, but it is not so far to become an excessive drain on one or more batteries internal to thecontroller 20. Longer ranges of 900 or more feet may also be advantageous, especially in those instances where the resulting reduction of battery life is not a major concern. - One embodiment of a method of response of the
computer 24 to the actuation of thebuttons controller 20 is illustrated inFIG. 2 . The method begins atstep 40 when thecomputer 24 receives a wireless transmission signal from thecontroller 20. As also shown below inFIG. 3 , the wireless message reception and analysis circuitry in thecomputer 24 is continually in the on-state, even when the remainder of thecomputer 24 is in an off-state. The signal received by thecomputer 24 advantageously includes at least two pieces of information for use by thecomputer 24. The first is a controller hardware identification code. The second is an instruction code that designates which application program, if any, should be launched. - At the
next step 42, thecomputer 24 checks the controller hardware identification code, and compares it to an internally stored identification code. If, atstep 44, these two codes match, thecomputer 24 accepts the remainder of the transmitted data and, atstep 46, stores the transmitted instruction code. If the codes do not match, atstep 48 thecomputer 24 ignores the remainder of the message. In analogy with garage door openers and automotive keyless entry systems, thisstep 42 allows simultaneous use ofdifferent controllers 20 in proximity to one another in a single office building for example. In this way, thecomputer 24 only responds to control instructions from thecontroller 20 in the possession of the operator of thecomputer 24. - After storing the instruction code, at
step 50 the computer initiates a power up sequence. As described below with reference toFIG. 3 , this step advantageously includes activating the computer power supply and loading the operating system software. Atstep 52, thecomputer 24 retrieves and interprets the stored instruction code, and atstep 54, the computer launches the appropriate application program as specified by the retrieved instruction code. - Referring now to
FIG. 3 , thecomputer 24 advantageously includes a processor andmemory circuitry 60 and astorage device 62 that may, for example, comprise a hard disk drive. Thecomputer 24 also includes remotecontrol interface circuitry 64 for receiving signals and/or data from theremote transmitter 20. Thecomputer 24 further includes apower supply 66 that supplies power to all of the electrical components of thecomputer 24. The processor andmemory circuits 60, thestorage device 62, and the remotecontrol interface circuitry 64 are coupled through abus system 70. Although not illustrated for purposes of clarity, those of skill in the art will appreciate that thebus system 70 will typically comprise a set of busses of varying format that communicate through bridge circuitry. The remotecontrol interface circuitry 64 may be incorporated into thecomputer 24 in a variety of ways. It may comprise a daughter printed circuit board which plugs into an expansion slot in thecomputer 24. Alternatively, it may be incorporated directly onto a motherboard in thecomputer 24 that also mounts the processor andmemory circuits 60. The remotecontrol interface circuitry 64 is continually powered by abattery 72 so that it can receive and process wireless signals transmitted to thecomputer 24 even when thecomputer 24 is in an off state. - The
storage device 62 stores, among other things,several application programs storage device 62 also contains a remote onprogram 76. In this embodiment, theremote controller 20 sends a signal to the remotecontrol interface circuitry 64 which includes thecontroller identification code 78 and one of theinstruction codes control interface circuitry 64 then compares the received identification code with a storedidentification code 84. If the two match, the remotecontrol interface circuitry 64 stores the received instruction code in aninstruction code register 86. - After storing the instruction code in the
register 86, the remote control interface circuitry activates thepower supply 66 by asserting anoutput 88 which is connected to thepower supply circuitry 66. This may be accomplished in a wide variety of ways which are well understood by those in the art. Asserting theoutput line 88 may close a relay in the AC power lines to the power supply, for example. In an advantageous embodiment, the power supply includes a low voltage secondary on/off signal line that toggles the supply from an off state to an on state when asserted. In this embodiment, theoutput 88 is coupled to this secondary on/off signal line. - Upon the application of power, the
computer 24 will load its operating system software. A variety of operating systems are currently utilized in the computer industry, including Unix™, Linux™, DOS™, and Windows™. At this time, a large majority of the currently commercially available personal computers automatically load Windows™ upon power up. Furthermore, Windows™ includes a Startup utility, which allows the user to list one or more application programs that Windows™ will load and run automatically when thecomputer 24 is powered up. - In the embodiment of
FIG. 3 , the remote onprogram 76 is listed in the Startup utility for automatic launch when the computer is powered up. The remote onprogram 76 causes the computer to perform an I/O operation to retrieve the instruction code stored in theinstruction code register 86. Using a table which is part of the remote onprogram 76 that cross references instruction codes withapplication programs program 76 determines which application program the user wishes to have launched, and initiates the loading of this user selected application program. - With the
controller 20 illustrated inFIG. 1 , depending on thebutton remote controller 20, different instruction codes will be sent and stored in theinstruction code register 86, resulting in the launch of different application programs. If the user only wants to power the computer up without launching a program, this may be accomplished by sending, for example, all zeros as an instruction code when theappropriate button 30 is pushed on thecontroller 20. This may be interpreted by the remote onprogram 76 as an instruction to load no additional application program. In addition, the remote control interface circuitry could be provided with aconnection 90 to the power supply output. In an embodiment with thisconnection 90, if the power supply is activated locally with the power switch, the power supply output may be sensed, and the remote control interface circuit could be configured load zeros into the instruction code register in response so that no application program is automatically loaded as may be the case with the remote power up procedure. A convenient remote controller is therefore provided which is easy to carry, simple to operate, and which saves computer users time. - The foregoing description details certain embodiments of the invention. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the invention can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the invention with which that terminology is associated. The scope of the invention should therefore be construed in accordance with the appended claims and any equivalents thereof.
