An imaging array provides a plurality of distinguishable bitmap images and comprises an array of sensor cells capable of sensing radiation. The cells are connected in a manner to form distinguishable bitmap images through a pattern of correspondence among the cells. Each bitmap image formed comprises a combination of one or more cells indicative of detecting an image pixel within a field of array cells that have been nonindicative of such detection. The pattern of correspondence may be one of in...

An array processor in which each sub-array of processing elements has a group of check-bit processing elements associated with it. The check-code processing elements have north-south interconnections, but have no east-west connections. Instead, the northernmost element of each group is connected diagonally to the southernmost element of the neighboring group, so as to permit serial transfer of check codes, over the north-south connections and the diagonal connections, between adjacent groups in ...

In a printed circuit, a plurality of drive electrodes are arranged in an array which is symmetrical about a center detector electrode. A plurality of conductive arms extend outwardly from the center electrode between adjacent electrodes in the array. One of the conductive arms extends to a contact point outside the array and provides electrical communication in the form of an electrical conductive path from the center electrode to the contact point. The remaining arms terminate substantially co-...

A capacitor array for a companded pulse code modulation voice codec includes a first plurality of capacitors having a common capacitance C each. A plurality of switching means individually and selectively couple one plate of each of the capacitors to a first point of reference potential or to a second point of reference potential. A second plurality of capacitors has a common capacitance 2C, each, which is coupled in series to form a plurality of junctions, each of the junctions being coupled to...

An array of gradient refractive index lenses designed to produce an erect image of an extended object. The lenses are supported in a matrix of light-absorbing cladding glass for stray light control.

A tactile stimulator is disclosed which comprises a stack of planar sheets of a piezoelectric polymer material, which in the preferred embodiment is PVF.sub.2. Each sheet has two opposed broad flat faces and at least one tactile surface at one longitudinal end. Separate electrodes cover portions of each flat face of the sheets in predetermined patterns. The electrodes from sheet to sheet are mirror images of the corresponding electrode patterns of the next adjacent sheet. Each of the sheets is p...

A switch assembly with a different combination of resistance and capacitance associated with each of a plurality of switches and with as few as two leads connecting the plurality of switches to external circuitry. The external circuitry detects switch activation by sensing combined resistance and capacitance across the switch leads.

A key array in which, progressing from key to key, the switching functions are derived by an AND-operation from mechanical or electrical signals indicating the actuation of pairs of adjacent keys of a row of keys or indicating the actuation of at least two diagonally opposite keys of a square group of four keys arranged in a rectangular keyboard. The pairs of adjacent keys and the square groups of four keys, respectively, each are allocated to a single symbol and each are depressable simultaneou...

The laterally contacting elastomeric array is preferably adapted for use in connecting the pin electronics in a test-head to an electronic device under test. The array comprises a plastic elastomer boat for supporting a plurality of elastomeric contacts, and an insulating thread or filament, or retaining nipples, for supporting the contacts in the elastomer boat. The contacts are each cylindrical, have a hole for receiving the supporting thread (filament) or nipples, and are compressed laterally...

In an exemplary embodiment, the transducer elements are arranged in rows and columns, the transducer elements bein contacted at both sides by oppositely disposed contact surfaces, and switches being associated with the contacts of the one contact surface as well as with the contacts of the other contact surface for the purpose of adjustment of preselectable transmitting and/or receiving surface of transducer elements during a transmitting/receiving cycle, in particular, for the purpose of dynami...
