Abstract: The present method defines a plurality of individual temperature sensor cells on a single printed circuit board with a separate temperature detector mounted in each cell. The temperature response of each detector is characterized substantially simultaneously and the values for series and parallel trimmer resistors for each cell are determined from the temperature response of the detector for the cell. Then an automated machine attaches properly valued resistors in parallel and in series with each detector on the printed circuit board.

Abstract: An enclosure for a film-type humidity sensing element includes identical enclosure members which snap together to form an enclosure with the humidity sensing element sandwiched between the members, each of the members including a lead mounting area on its inner surface for mounting the mounting ends of electrical leads, the leads being connected to contact portions of the humidity sensing element interiorly of the enclosure by a metal-filled conductive adhesive which is introduced into the enclosure through access openings after the enclosure members have been assembled together. The enclosure is adapted for mounting on a circuit board in both horizontal and vertical orientations and independently of the lead structure of the sensor assembly.

Abstract: A pivotal electrical connector for connecting a shape memory alloy element in the form of a coil spring to a fixed member, the connector including a strip of electrically conductive material having a clip or a pair of legs for securing the connector to one of the coils of the element. A pair of holes may be provided in the strip through which the coil is threaded. A rotational connector is provided in the strip for engaging the fixed member.

Abstract: A fluid pneumatic circuit board includes a base plate and a flat cover plate molded of a suitable plastic such as polysulfone. The plates are chemically bonded with a thermal adhesive such as a refrigerated solid sheet of epoxy. The base plate has a planar surface within which the fluid circuit passageways, as well as structural board and component supports are integrally molded. The cover plate has individual sealing ribs formed to encircle each of the passageways. The epoxy sheet is shaped to cover the passageways, and with openings aligned with the exhaust openings in the cover plate. The plates, with the adhesive sheet therebetween, is clamped together and heated in an oven to soften the adhesive. The sealing rib has inclined sidewalls and an outer flat sealing wall, with an included angle of 60.degree. and a tip width equal to the sheet thickness and a height equal 21/2 times the sheet thickness. Moisture and/or gas in the softened plastic escape from under the tip and prevent formation of bubbles.
