  • Patent number: 7273993
    Abstract: A keypad (102) for entering data in an electronic device (100) is disclosed. The keypad includes a first carrier (302), a key panel (202), and a backlighting module (204). The key panel is coupled to a first side of the first carrier and the backlighting module is coupled to a second side of the first carrier.

  • Patent number: 4268805
    Abstract: A circuit for coupling a citizens band transceiver and a broadcast band receiver to a standard automobile antenna. The circuit is comprised of an impedance transforming network connected in series with the standard automobile antenna and a parallel-tuned circuit in series with the broadcast band receiver. The series-tuned network is comprised of a split capacitance for stepping the impedance down from the citizens band transceiver to the lower impedance of a standard automobile antenna. The series-tuned circuit also includes a tuning coil for matching the output of the network to the particular automobile antenna. In series between the automobile antenna and the broadcast band receiver is a parallel-tuned circuit comprised of a capacitor and a tuning coil. To prevent multiplication and excessive voltages in the event the broadcast band receiver should become disconnected, a limiting resistor connects the parallel-tuned circuit to ground.

  • Patent number: 4112377
    Abstract: A converter is disclosed for converting 23-channel citizens band to provide citizens band reception through a standard radio, preferably an automobile radio. The circuit is comprised of an RF amplifier and self-oscillating converter which is switched into the antenna connections of an automobile radio. Conventional auto antenna connectors facilitate easy installation. A pushbutton switch connects the citizens band converter into the line connecting the antenna with the radio. The pushbutton switch also grounds the converter output when switched to standard radio to prevent interference with standard radio reception.

  • Patent number: 4097894
    Abstract: A secured scramble decoder filter comprised of a narrow band filter assembled on a fragile substrate and mounted in a housing wich automatically destroys the filter when any tampering is attempted. The filter is a series tuned network bridging a conductor coupled through a capacitor to a parallel tuned network, which is connected to ground. The coils for the filter are printed on a special electronic glass tube for temperature stability while the capacitors are deposited on the fragile substrate. The filter is mounted in a sealed housing in brackets with a spring, loaded to break the substrate when the device is tampered with to render it inoperative. The device is provided with a mounting screw requiring a special tool for removal so that when the device is mounted any prying in an attempt to remove the device will trigger the destruction of the filter.

  • Patent number: 4074311
    Abstract: A system for subscription TV security which is comprised of a scramble signal generator which adds a modulated RF carrier signal to the TV channel transmission. Preferably the frequency of the scramble signal generator is selected to fall within the band of frequencies of the TV channel between the video carrier and the audio carrier. The TV channel is transmitted to receivers encoded with the scramble signal carrier providing false and misleading information, preventing the receiver from reconstituting a coherent picture or sound while this scramble signal is present. The transmitted signal is decoded, (i.e. scramble signal removed), restoring regular reception by filtering with a sharply tuned high-Q notch filter attached to the drop line going to a TV receiver. By careful selection of the band width and attenuation of the filter and pre-emphasis of the channel band, degradation of the video information is prevented.

  • Patent number: 3994312
    Abstract: An inflation pressure regulator which automatically releases pressure above a predetermined maximum. The regulator has a tubular base extending into the hollow interior of a housing. A collar slideably mounted on the tubular base is biased against the interior of the housing with a coil spring to regulate the pressure. An inflation gas is supplied through the neck of the housing which has a plunger extending through the tubular base. A threaded cavity in the base permits permanent installation on an inflation valve.

  • Patent number: 3958542
    Abstract: An auxiliary apparatus or device for attachment to an internal combustion engine, so that at a certain point in the depression of the accelerator pedal, an increased resistance to further depression of the pedal is abruptly encountered. This point is constantly adjusted in accordance with the engine vacuum so that when engine vacuum is high, considerable depression of the pedal is permitted before the resistance is encountered, and conversely when the engine vacuum is low, the resistance point is soon encountered. This is effected by attaching one end of a cable to the throttle mechanism of the engine and attaching the other end to a vacuum actuated bellows. When the slack in the cable is taken up, added resistance is provided in the form of a loading spring, which requires increased foot pressure against the accelerator to overcome.
