    Abstract: An electrical interconnection system comprises a bifurcated, multilayer flex circuit having electrode pads on the inner surfaces of the bifurcation. Electronic components are mounted on one or both sides of the flex circuit by conventional means. When the bifurcation is spread apart, the electrode pads are alignable with respective contacts on a printed circuit board. After bonding the pads to the contacts by soldering, conductive adhesive, or other means, a secure electrical connection is maintained while still allowing the flex circuit to bend somewhat from side to side, creating additional design options not available with rigidly mounted components and modules.

    Abstract: A position transducer has an input shaft coupled to a variable inductance sensor to produce an output electrical signal representing shift angle position. The transducer includes a plurality of rigid circuit boards which are hinged to one another so that the circuit boards and the electronic circuitry supported on the boards can be wrapped around the variable inductance sensor. The individual rigid circuit board segments are laminated onto a flexible sheet having conductive tracks. The track sheet provides the hinged effect.The power supply which is mounted on one or more of the boards provides DC power through an AC circuit fed by a transistor which is switched on and off as a function of the power needs of the transducer. By thus having an ON duty cycle substantially less than 100 percent, the heat generated in the power supply is minimized thereby making feasible the packing density afforded by the plurality of hinged circuit boards.
