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.
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 in 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
The controller 20 also incorporates internal wireless transmission circuitry and an antenna (not shown) for wireless communication with a computer 24 that incorporates an antenna 26 and a wireless receiver. These aspects of the computer 24 will be described in more detail below with reference to
As shown in
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 the controller 20 and computer 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 the computer 24, but it is not so far to become an excessive drain on one or more batteries internal to the controller 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 the buttons 30, 32, 34 on the controller 20 is illustrated in
At the next step 42, the computer 24 checks the controller hardware identification code, and compares it to an internally stored identification code. If, at step 44, these two codes match, the computer 24 accepts the remainder of the transmitted data and, at step 46, stores the transmitted instruction code. If the codes do not match, at step 48 the computer 24 ignores the remainder of the message. In analogy with garage door openers and automotive keyless entry systems, this step 42 allows simultaneous use of different controllers 20 in proximity to one another in a single office building for example. In this way, the computer 24 only responds to control instructions from the controller 20 in the possession of the operator of the computer 24.
After storing the instruction code, at step 50 the computer initiates a power up sequence. As described below with reference to
Referring now to
The storage device 62 stores, among other things, several application programs 74a, 74b, 74c. As discussed above, it is one of these programs that the user may wish to remotely launch. The storage device 62 also contains a remote on program 76. In this embodiment, the remote controller 20 sends a signal to the remote control interface circuitry 64 which includes the controller identification code 78 and one of the instruction codes 80 or 82. The remote control interface circuitry 64 then compares the received identification code with a stored identification code 84. If the two match, the remote control interface circuitry 64 stores the received instruction code in an instruction code register 86.
After storing the instruction code in the register 86, the remote control interface circuitry activates the power supply 66 by asserting an output 88 which is connected to the power supply circuitry 66. This may be accomplished in a wide variety of ways which are well understood by those in the art. Asserting the output 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, the output 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 the computer 24 is powered up.
