  • Light Strip with Environmental Electrical Switches
    Publication number: 20180116032
    Abstract: A light strip may be fashioned from a plurality of environmentally controlled parallel light circuits positioned on a flexible, rigid or rigid-flexible circuit board. Each circuit may then be activated or deactivated discretely by triggering the appropriate environmental condition as to the preference and desire of the end user. Such light strips may then be easily deployed in multiple environments for the purpose of illumination.

  • Miniature, low power, electromechanical safety and arming device
    Patent number: 5902953
    Abstract: The blocking disc serving as an explosive train interrupter of a safety and rming mechanism is angularly displaced from its safe position by a stepping motor through reduction gearing in response to timed energizing pulses applied thereto from a crystal-controlled pulse generator. The blocking disc is releasably latched in its safe position by a locking rod controlling the supply and cut-off of energizing voltage to the pulse generator to accurately time displacement of the disc to an armed position.
