  • Patent number: 6794992
    Abstract: A hand-held remote control unit for controlling the operation of a television and other electronic audio/video components, such as a VCR, DVD player, or home stereo, operates in a different mode for use as a video game controller. The location and position of the push buttons on the remote controller unit are arranged such that a subset of the buttons that are used for the television remote control are operable in a different mode as a video game controller. A user rotates the remote control unit from a vertically upright position to a horizontal position to use the remote control unit for operating a video gaming system. When used as a video game controller, the controller indicates which of the subset of buttons on the remote control are to be used for operating the video game.

  • Publication number: 20040174246
    Abstract: A system used to open a vehicle door consisting of a multiple radio frequency transmitter and a similarly coded radio frequency “RF” receiver. Said receiver is capable of generating a momentary RF trigger signal when a valid coded radio frequency signal is received. The system also incorporates a control switch connected to a vehicle transmission shift sensor that will produce an in-park signal when the vehicle's transmission is in park and a controlled on/off switch that will produce an on signal when the switch is in the on position. A control circuit will produce a ready signal when said in-park and on signals are present that is used to enable a door latch release circuit and activate a status indicator. The system will operate a bi-directional electric solenoid to operate a vehicle door latch mechanism in a direction necessary to open a vehicle door when said ready signal and RF trigger signals are present.

  • Patent number: 6781519
    Abstract: A method for remotely controlling a vehicle audio system, which is controlled in accordance with an instruction from an infrared remote control unit, uses a radio frequency remote control unit to remotely control the vehicle audio system. A security system receives a command transmitted from the radio frequency remote control unit. In a security control mode, the vehicle security system performs security control based on the command. In an audio control mode, the security system transmits the command to an audio control interface unit. The audio control interface unit converts the command transmitted from the security system into an infrared remote control unit command. Based on the infrared remote control unit command, an infrared emitter is driven to emit infrared rays, thus controlling the vehicle audio system by the infrared rays.

    Abstract: A garage door opener comprises at least two radio frequency transmitters, a radio frequency receiver, at least two memories, and a processor. Each memory corresponds to one radio frequency transmitter and stores a code of a corresponding radio frequency transmitter. The radio frequency transmitter is connected to the processor by electrical connectors. It is impossible to mis-study to the other radio frequency transmitter because the processor in the host computer has no program mode. Since each memory corresponds to one radio frequency transmitter, when one radio frequency transmitter is lost, a corresponding memory is eliminated to make the lost radio frequency transmitter disuse.

    Abstract: A wireless security system using multiple receivers in which each RF receiver can monitor the messages being sent to the control by the other receivers via constant monitoring of the bi-directional communication between the control and all of the other receivers on the bus. If a message in a first receiver's transmission buffer matches a message that has already been acknowledged by the control from a second receiver, the first receiver can discard its duplicate message. This significantly reduces the number of messages that the control's communication bus needs to handle, especially during the disarmed state of the system as indicated earlier.

The deadbolt is fixed with a stopper on the center portion. The locking button of a remote controller is pressed to send out a locking signal to the circuit board to start the motor of the actuating device to rotate. Synchronously, the rotating shaft of the motor actuates a rotary member to rotate together with its notch, which rotates to reach the stopper of the deadbolt and holds the stopper immovable therein, rendering the deadbolt unable to be moved inward. Thus even if the lock rods of the lock base are pried unlocked, the door lock is still impossible to be unlocked before the actuating device is driven by a remote controller to release the deadbolt, having best effect of anti-theft.

  • Patent number: 6683527
    Abstract: A security system which is suitable for use in a vehicle. The security system is a passive entry and passive re-mobilization system in which a security controller transmits a command signal LCs to a remote transponder, which replies with a LF response signal LRs. If an LF response signal is not received in response to the transmission of a command signal LCs, the security controller re-transmits the command signal, again as an LF command signal LCs. On determining that a command signal is a re-transmitted command signal, the remote transponder re-transmits the response signal as an UHF response signal URs.

  • Patent number: 6681110
    Abstract: An apparatus to control remote devices or equipment via existing cellular telephone networks. The apparatus receives information from a customer concerning a specific function, which the customer wants to perform at the remote equipment. A Central Control receives this information from the customer and correlates the function to a specific cellular telephone MIN number, which has been pre-programmed in a computer at the Central Control. The MIN number is then sent to a cellular provider. The cellular provider then transmits the MIN number to an antenna, which transmits the MIN number to a remote equipment controller at the remotely located equipment. The remote equipment controller then takes the a part of the MIN and gives these numbers to a PLC at the remote equipment controller. The PLC then memory maps the part of the MIN to a specific function to be carried out by the remote equipment controller. Then the remote equipment controller carriers out specified functions at the remote equipment.

  • Publication number: 20040004537
    Abstract: A vehicle remote control system includes a multi-bank remote transmitter to be carried by a user and having selectable signal banks, such as for different vehicles. The vehicle remote control system also includes a controller at the vehicle that is switchable to a first mode for learning at least one signal bank from the remote transmitter based upon transmission therefrom to define a learned operable signal bank for thereafter controlling at least one corresponding vehicle function. The controller is also switchable to a second mode for deriving at least one other operable signal bank based upon the learned operable signal bank so that the controller is responsive to the remote transmitter without learning the other signal bank. Accordingly, in some embodiments the controller may be responsive to the multi-bank remote transmitter irrespective of the selected banks.

    Abstract: A vehicle remote control system includes a remote transmitter to be carried by a user for selectively transmitting signals, and a controller for receiving the signals. The controller includes outputs and is switchable between first and second output operating states. In the first output operating state, the controller operates a first output based upon a first occurrence of receiving a first signal from the remote transmitter, and operates a second output based upon a second occurrence of receiving the first signal from the remote transmitter within a predetermined time of the first occurrence thereof.

  • Publication number: 20030210131
    Abstract: A movable barrier operator having thumbprint identification in either a remote radio frequency transmitter, or a receiver/barrier operator system or both is provided. A control circuit with a non-volatile memory receives thumbprint information from a fingerprint detector device and stores the information, identifying an authorized user. On subsequent operation of the fingerprint detector, a fingerprint data set is received in the control circuit and an attempt is made to match the incoming data with previously stored data thus establishing the identify of the user according to highly reliable biometric principles. As an option, a variety of different actions can be taken based upon the perceived identity of a particular individual, as well as the type of device communicating with the receiver/barrier operator.
