Abstract

1,097,094. Electric selective signalling. LONDON ELECTRICITY BOARD, and D. C. GREEN. July 18, 1966 [April 16, 1965], No. 10184/65. Heading G4H. An electrical switching system comprises means for forming a visual display of information pertinent to at least one of a number of possible switching operations superimposed upon a multiplicity of electrical switches at least some of said switches being in register with selected parts of said display and representing a choice of switching operation relating to said selected parts. A cathode ray tube is controlled by a computer to produce a display superimposed upon a matrix of row and column wires, mutually insulated at the cross-points. By placing his finger on a cross-point, an operator alters the capacitance between the two wires thereat. The rows and columns are scanned in turn, e.g. by reed relays controlled by electronic logic, to detect the change in capacitance, the changed location being identified to the computer which alters the display and/or controls a system in response. The controlled system may be an electricity supply network, route indicator, teaching machine, retail shop, manufacturing plant, or air booking system. Measurements in the controlled system and the results of calculations may also be displayed.
