Patent number: 10121576Abstract: The pressure based control engine directs the amount of amperage that is applied to an electric device, such as a flashlight. The control engine provides a first piston body and a second piston body that conduct electricity.

Patent number: 3937980Abstract: When a conventional printed wiring board is subjected to a harsh environment, leakage can develop between adjacent conductors over a period of time. If high impedance circuits are employed on the board, such leakage can adversely affect circuit performance. The effect of such leakage can be minimized if the circuit layout is so arranged that potentially troublesome leakage occurs only to elements that operate at comparable operating potentials. In one embodiment of the invention, a circuit is shown having a high impedance point on a printed wiring board intended for an automotive application. The high impedance wiring conductor is completely surrounded by a metal conductor that is connected to a potential point in the circuit that approximates the potential at which the high impedance point will operate. When the automotive environment results in surface leakage, there will be very little change in the operational character of the high impedance circuit.Type: GrantFiled: September 16, 1974Date of Patent: February 10, 1976Assignee: Aeronutronic Ford CorporationInventors: Helmut G.
