| 141 | Keyboard encoder | US3696411D | 1970-11-12 | US3696411A | 1972-10-03 | KILBY JACK S; TASSEL JAMES H VAN |
| Disclosed is a keyboard encoder capable of directly encoding decimal input information into electrical binary code. The electrical encoding of the information appears at the output terminals of the encoder when the key representing the information to be encoded is depressed. The depressed key causes the selective shorting together of certain ones of a group of encoding conductors which are connected to the output terminals.

| 155 | Method for making area actuated switch | US396506 | 1982-07-08 | US4724605A | 1988-02-16 | Charles M. Fiorella |
| Disclosed is an area actuated switch which can be used, by way of example, in a keyboard for a calculator, learning aid or the like. An area actuated switch array is formed using two insulating sheets made of polyester or polycarbonate; the insulating sheets overlie one another such that one side of each sheet faces one another. Groups of spaced conductors formed on each of the facing sides also overlie one another, and selected conductors traverse the periphery of the keyboard. A plurality of raised, insulating spacer areas or points are positioned on the facing sides and are in registration and contact with each other. An insulating substrate is formed over the conductors traversing the periphery and this insulating substrate has substantially the same thickness as the spacer points such that the spacer points and the insulating substrate prevent the spaced conductors from making electrical contact. An adhesive coating, which may be heat or pressure sensitive, is applied to the spacer points and the insulating substrate to bond these two parts together. The bond created by the adhesive coating over the insulating substrate prevents contamination of the keyboard from dust, humidity and the like. The keyboard structure, therefore, may have an infinite active area such that when pressure is applied anywhere within the periphery of the switch array, electrical contact is made. | ||||||

| 157 | Circuit board with contact positions, as used for telecommunications terminals and other apparatus | US785114 | 1985-10-07 | US4647729A | 1987-03-03 | Geoffrey A. Collar; John S. Moss; Pak-Jong Chu; Paul D. McDonald; Brian E. Voss |
| A circuit pattern on a circuit board, as used in telecommunications systems and other electrical apparatus, often has contact positions for switches, such as pushbutton switches, and for other purposes. The normal copper circuit pattern is covered at the contact positions to give improved contact conditions. Carbon ink has been proposed by obtaining the necessary high level of alignment of carbon ink with the copper pattern at contact positions is difficult as such contact positions have very close members. The invention proposes contact positions having closely spaced inter-digital contact members, in which the circuit pattern extends to and stops at the peripheral region of a contact position, the contact members being of carbon ink and overlapping conductors of the circuit pattern at the peripheral region. | ||||||
