  • 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.
