  • Motion sensitive switch and circuitry
    Patent number: 6788201
    Abstract: A motion sensitive device for causing an electronic signal to be sent to one or more output devices, comprising a printed circuit board, a battery connected to the printed circuit board, electrical circuitry connected to the printed circuit board, a motion sensitive switch connected to the printed circuit board, electrical output devices such as light emitting diodes connected to the printed circuit board and electrical circuits all providing means whereby the motion sensitive switch causes a signal to be transmitted to the output device when movement is sensed by the switch. The device is small enough to be used in wearing apparel and can provide safety vis-à-vis increased visibility for the user.

  • Warning light adapted for use with a stop sign
    Patent number: 6031468
    Abstract: A warning light is provided to be coupled to a stop sign. The warning light includes a main unit, a holder for cooperating with the main unit to couple to the stop sign, a solar cell for converting solar energy into electrical energy, a light emitting element disposed in the main unit, an energy storage device coupled to the solar cell for storing the electrical energy, and a charge control circuit coupled to the solar cell, energy storage device and light emitting element. The charge control circuit selectively directs electrical energy from the solar cell to energy storage device, or from the energy storage device to the light emitting element.

  • Automobile electronic alarm device
    Patent number: 5148145
    Abstract: An automobile electronic alarm device alternatingly produces an alarm sound signal and a speech sound signal when an attempt to burglarize or steal the automobile is made. The speech sound signal can correspond to a combination of the digits found in a license plate of the automobile so as to provide a distinct alarm sound output.
