摘要： A board-to-board interconnect socket (40) provides electrical interconnection between printed circuit boards (50, 52). Resilient metalized particle interconnects (28) are disposed in holes in a rigid substrate (14) of desired thickness. Each resilient interconnect (28) includes first and second cap members (18, 20) that extend from opposing ends of the hole and beyond the respective surfaces of the substrate. The first and second cap members (18, 20) may be connected with a stem member (22) or conductive paste (34) that is disposed inside the hole. The hole may be lined with conductive material (26) such as conductive plating to facilitate conduction of electricity.

摘要： The present invention comprises an electrical contact having solid homogenous conductive particles on the contact surface. The particles are of greater hardness than that of the contact material to deform the contact material and cause breakage or fracture of the oxide or other contaminating layer, or to penetrate the contaminating layer. The particles are applied to the contact surface by a technique which results in the particles being intimately bonded to the contact surface, usually as a layer of particles. A preferable technique for such particle application is hypervelocity oxygen fuel spraying (HVOF) or plasma spraying, by which the particles are embedded on the contact surfaces to provide a substantially permanent interparticle bond between the applied particles and the contact material.

摘要： A method for manufacturing hygristors includes preparing a hygroscopic gel containing a substantially greater proportion of carbon than the prior art, and milling the gel for a period of at least 24 hours to produce a smooth mixture. Substrates are dipped into the milled gel at controlled rates to coat the substrates. The coated substrates are cured under controlled temperature and humidity. Adhesion of the coating is improved by the smoother mixture resulting from the longer milling time, and by the differences in components of the mixture compared to the prior art. Long term stability and dynamic range are both increased.

摘要： A dust sensing apparatus uses a transducer element oscillating at a resonant frequency to detect changes in dust concentration. The transducer is fabricated from a polymer material which oscillates when a voltage is applied. The presence of dust affects the oscillation frequency. Dampening of the frequency by the dust presence changes the electrical resistance provided by the transducer. Electronic circuitry computes the level of dust by measuring and controlling the level of the AC signal required to maintain the oscillation frequency by monitoring the resistance.

摘要： Several different types of electrical switches are disclosed. In one particular embodiment, an electrical switch is disclosed comprising: a molded case having a pair of conductive terminal contacts; and a molded actuator for mating with the case. The actuator is movable between a conducting position and a non-conducting position within the case, and the actuator has at least one spring member and a conductive contact surface. The spring member forces the actuator into the non-conducting position, and the conductive contact surface provides an electrical connection between the pair of conductive terminal contacts when the actuator is in the conducting position. The actuator is retained within the case by a retaining member and/or a snap member. The case and the actuator are molded about the conductive terminal contacts and the spring members, respectively. Furthermore, the conductive contact surface is formed of a conductive elastomer that is grafted to the actuator. In other embodiments, the spring members are molded as a part of the actuator or the case, or the spring members are connected to the conductive contact surface or the conductive terminal contacts with the actuator and the case being molded thereabout, respectively.
