Abstract:
A reconfigurable device for terahertz (THz) or infrared (IR) ranges that includes a base substrate, a lower array attached to the base substrate, and an upper array attached to the base substrate and at least partially suspended over the lower array. Activation of the reconfigurable device causes the upper array to mechanically flex towards the lower array so that electrical contact is made therebetween. Methods of fabricating and operating the reconfigurable device are also provided.

Abstract:
A switching device for breaking an electric current including a main contact carrier, movable and stationary main contacts, the movable contact attached to the main contact carrier, an arcing contact carrier, a movable and stationary arcing contacts, the movable arcing contact attached to the arcing contact carrier and the stationary arcing contact arranged in parallel with the stationary main contact, and an actuating unit for the main and arcing contact carriers between open and close position at an actuating distance, wherein there are separation distances between the stationary and movable contacts of the main and arcing contact units respectively when the current is interrupted. The switching device further includes a first rack and a first gear for actuating the arcing contact carrier so that, when interrupting the current, a separation distance between the arcing contacts is longer than a separation distance between the main contacts.
Abstract:
A keypad encoding circuit contains a voltage dividing network and an integrated circuit. The voltage dividing network includes a string of resistors that generates an encoding signal voltage. The integrated circuit converts the encoding signal voltage into a digital value indicative of which of the keys has been pressed. The cost of the voltage dividing network is reduced by forming the resistors from a layer of conductive carbon and avoiding the cost of providing discrete resistors. Each resistor has the same resistance even where the dimensions of the conductive carbon patches that form the resistors vary. Providing the resistors does not involve additional manufacturing cost because the resistors are made in the same step as are the landing pads of the voltage dividing circuit. Manufacturing costs associated with etched printed circuit board layers are avoided because inexpensive printed layers are used to realize the required traces and resistors.
Abstract:
A conductive tracing for a keyboard including a pair of electrically conductive paths that are electrically isolated from each other. The pair of electrically conductive paths may each include conductive surfaces that are electrically coupled together. Each of the plurality of conductive surfaces of the pair of electrically conductive paths extend radially between a canter portion and a peripheral portion of the conductive tracing. One or more of the conductive surfaces may include a pair of outer edges that are substantially parallel to a respective radial direction that the outer edges extend in. The conductive surfaces of one of the pair of electrically conductive paths may be complementary formed to the conductive surfaces of another of the pair of electrically conductive paths. The conductive tracing may be substantially symmetric about an axis that passes through the center portion of the conductive tracing.
