  • Patent number: 6307304
    Abstract: A piezoelectric active-mode incrementor switch system (100) includes two ratchet wheels (118, 124) that are rotationally mounted on a drive shaft (112) having a knob (102). The ratchet wheels (118, 128) form a slipping clutch with their respective drive wheels (116, 128) which are rigidly mounted to the drive shaft and mechanically loaded with spring (120). The ratchet wheels (118, 124) are mounted inversely to each other on the drive shaft (112) and make contact with their respective cantilever beams (114, 136) which each have a piezoelectric film. In operation, the switch (100) functions by mechanically stimulating the piezoelectric beams. When the knob (102) is rotated in one direction, only one of the beams (114, 136) is displaced causing a generation of an electrical charge that acts as a signal. The other beam (114 or 136) is prevented from moving and therefore its beam does not produce a signal.

  • Patent number: 5557064
    Abstract: A conformal shield (10) includes a conformal shield base (15), and a conductive layer (16). The conformal shield base (10) has a first conformable insulating material (12) having a characteristic softening point at a first temperature. A second conformable insulating material (14), which has a characteristic softening point at temperature higher than the first temperature, is overlaid on the first conformable insulating material (12). The conductive layer (16) is disposed on the conformal shield base (15) to form the shield (10).

  • Patent number: 5493478
    Abstract: A cam actuated control device (10) is provided. The control device (10) includes at least two momentary switches (13, 14) which are surface mounted on a circuit substrate (12). An actuating member (20) having a contoured cam surface (25) is movably positioned proximate to the switches (13, 14) such that movement of the actuating member (20) selectively actuates the switches (13, 14) to produce a binary encoded output.

  • Patent number: 5481618
    Abstract: A speaker assembly (100) includes a speaker (202) having at least one speaker terminal (206) and a magnet (204) which generates a magnetic field. The speaker assembly (100) also includes a circuit board (116) having at least one terminal (110). A metal member (106) is coupled to the circuit board (116) and is used to magnetically attach speaker (202) to circuit board (116). Upon speaker (202) being magnetically coupled to circuit board (116), the at least one speaker contact (206) becomes coupled to speaker terminal (110). Thereby, allowing for a quick way of attaching and detaching speaker (202) to and from circuit board (116).

  • Patent number: 4619275
    Abstract: Apparatus for discharging accumulated electrostatic charge from the human body includes a conductive ring to be worn on a finger. A first connector is attached to and electrically connected to the conductive ring. A cable with a mating connector plugs into the first connector. A second connector at the other end of the cable is connected to ground. A series resistor, located in the mating connector housing, limits current flow to a safe level in the event the user comes into contact with a high voltage high current source.

  • Patent number: 3970801
    Abstract: This apparatus is especially useful as a conversion kit and includes a new front cover for a portable radio telephone having a plurality of push buttons mounted therein, which push buttons activate a tone generator, the tones from which are applied to a timer and through a multi-contact relay to the speaker and transmitter of the radio telephone. The timer is utilized to activate the relay for 90 milliseconds each time a tone is produced by the tone generator so that a tone is transmitted for only 90 milliseconds and when a tone is not being generated the transmitter is connected to a microphone and the speaker is connected to the receiver in the normal operating manner by the relay.
