摘要:
Methods and systems for selecting and connecting an electronics package to a power source from one or more of a plurality of possible power source paths. An embodiment of the invention uses inexpensive analog components to select a power path by testing the possible power source paths for a desired potential. The invention interrupts the alternate power path while maintaining the connection of the electronics package to the power source through the selected power path. An optional removal circuit removes the testing and selection circuitry once the alternate power path is interrupted. In actual embodiment of the invention, the methods and systems described are included in a reversible circuit breaker.

An electrical architecture for an aircraft is provided. The electrical architecture is particularly suitable for relatively small, compact, and lightweight aircraft. In one embodiment, the electrical architecture includes an electrical generator component coupled to the aircraft engine, and an air compression system coupled to the electrical generator component. The electrical generator component is configured to receive mechanical power from the engine and to generate a constant frequency AC electrical power from the engine mechanical power, and the air compression system is configured to receive the constant frequency AC power as an input and, in response thereto, produce a pressurized air output having variable characteristics (for example, a variable flow rate or a variable air pressure).

An apparatus and method for simulating arcing events for use in testing arc fault circuit interrupters. The apparatus and method utilizes a plurality of motion sensitive switches, for example, mercury switches or ball-tilt switches, secured within the housing. When the apparatus is moved the switches interrupt a current flow mimicking arcing events.

A light emitting diode (LED) assembly is provided for use as an airplane position light which meets Federal Aviation Regulation lighting requirements and lasts longer than conventional incandescent and halogen position lights, while being relatively lightweight, cheap, and requiring relatively little power for operation. The LED assembly includes a first plurality of circuit boards in electrical communication with a base circuit board, wherein each circuit board of the first plurality of circuit boards is parallel to every other one of the first plurality of circuit boards, but is disposed at an acute angle to the base circuit board. The LED assembly also includes a second plurality of circuit boards in electrical communication with the base circuit board, wherein each circuit board of the second plurality of circuit boards is disposed at a different angle to the base circuit board such that the second plurality of circuit boards form a fan-shaped structure. In addition, the LED assembly includes a plurality of light emitting diodes electrically mounted to said first plurality of circuit boards and to said second plurality of circuit boards. The circuit boards and LEDs may be identical to facilitate construction and maintenance of the aircraft position light, and to decrease the cost of manufacturing the aircraft position light. Furthermore, LEDs may be chosen to comply with Federal Aviation Regulations lighting color requirements, obviating the need for a position light cover.
