Abstract: A signal connector assembly with a plug contact within a plug having a high resistive portion. When the plug of the assembly first makes contact with the electrical receptacles within a mating receptacle, the high resistive portion prevents a current surge. As the plug is further inserted into the receptacle, the energy passing from the plug to the receptacle is gradually increased. Eventually, the receptacle contacts within the receptacle pass the high resistive portion and make contact with the conductive portion of the plug contact, thereby permitting transmission of valid signals without the generation of spurious errors.

Abstract: An electrical power control system is adapted for controlling power and lighting in a building. Switch controls have either relays or triacs, controlled by microprocessors, to switch power on electrical branch circuits. An interface device 122 communicates with the switches 124,126, arranged in a multidrop configuration, with variable length data packets over serial branch circuits or data buses 142. In addition to being controlled by the interface device 122, the switch controls also have local switch actuators. The actuation of the local switch controls can be used by the interface device 122 as a control inputs to initiate other actions. Adaptive polling of switch controls is used to minimize system response time, and both transmit and receive signals are carried between the switch controls and the interface device 122 at different times on the same twisted pair wires. The interface device 122 can also communicate with a home automation system controller.

Abstract: An electrical receptacle contact is provided having contact beams which are asymmetrically opposed, defining a terminal receiving section therebetween. Asymmetrically opposed contact beams may have various widths to provide an appropriate spring force for a selected plating material, while ensuring that the receptacle contact maintains the same overall dimensional shape as contacts made with a different plating material. Although allowing for variable spring rate in limited dimensioned contact, susceptibility of fracture of the contact of the present invention during forming is minimized.

The structure includes a semiconductor substrate having an epitaxial semiconductor layer thereon, the substrate and epitaxial layer being of the same conductivity type. The structure further includes a source layer and a drain layer, each layer being of a second conductivity type, and a channel layer disposed between the source layer and the drain layer. The channel layer has an oxide layer and a gate disposed thereon. At least one of a wet anisotropic and a reactive ion etching step is performed to define a trench having a maximum width of about from 4-6 microns and a depth that extends well into the substrate. An electrically conductive via is then formed by deposition of metal into the trench to thereby establish a low resistance path between the source and the substrate ground.

In the event that continuity is not detected, an error signal is generated indicating a malfunction.

Abstract: The present invention provides a circuit device which insures highly-reliable electrical connections even when used in environments involving large temperature variations, and which can be easily assembled. Board assembly (10) has a housing (50) which is mounted on an edge (150) of a circuit board (100). Edge (150) includes protruding sections (160) on which a plurality of contact pads (180) are aligned.

Reinforcing sections (55) are disposed on both sides along the lengths of the slots (52). A connector, which engages with a mating connector, is formed by the protruding sections (160) and the housing (50). Since the edge (150) of the circuit board (100) is maintained in a substantially flat-plate shape even in cases where deformation caused by heat occurs in other portions of the circuit board (100), highly reliable electrical connections with mating connectors can be realized.
