摘要： An improved thermal printhead is disclosed which includes a plurality of addressable electrodes, each corresponding to a spot to be printed. In alternative embodiments, a single common electrode or a plurality of common electrodes are located in a plane below that of the addressable electrodes and are separated therefrom by an insulating layer. A portion of the common electrode is left exposed in the vicinity of each of the addressable electrodes and a covering of thermal resistive material electrically interconnects the two types of electrodes. Passage of a current through an addressable electrodes result in a current flow to the nearest points on a common electrode causing local heating in the resistive material. The electrode arrangement permits printing closer to the edge of the printhead and further, enables smaller, more clearly spaced printed "dots".

摘要： A capacitive touch panel comprising an array of touch sensitive switch cells, the panel including relatively small area touch switch elements located on closely spaced centers, that can be of transparent construction particularly suited for use with data processing equipment and electronic displays. Each switch cell includes a first and a second pair of series connected capacitors energized by a common signal source, the array of switch cells being arranged so that the first pair of capacitors are connected in first groups of switch cells, such as rows, to a corresponding first plurality of signal detectors, and the second pair of capacitors are connected in second groups of switch cells, such as columns, to a corresponding second plurality of signal detectors, the junctions of each pair of capacitors of a single switch cell being selectively coupled to ground by the body or other touch capacitive means for actuating a selected switch cell.

摘要： A non-fouling print finger having an integral shield. The shield guides rdue passed the print stylus to a reduced area of the print finger body from whence the residue falls from the print finger. The shield also prevents excessive bending of the print stylus movable arm in the reverse direction during cleaning.
