Filed:

Jan 11, 1980

Appl. No.:

6/111405

Inventors:

Lanny C. Davis - Buffalo Grove IL

Assignee:

CBS Inc. - New York NY

International Classification:

G09B 1502
G10B 310

US Classification:

84343

Abstract:

A stop control panel for an organ includes an elongated support panel on which modular groups of touch sensitive switches are disposed in pairs with an indicating lamp disposed between the switches of each pair, wherein the switches of the pair respectively actuate and de-actuate a given stop while the lamp indicates whether the stop is actuated. The touch sensitive switches are overlaid with a front surface layer through which the switches are operable by touch of the layer and through which the indicating lamps are observable when energized. The surface layer has printed thereon a plurality of color-contrasting outlines, each positioned to circumscribe a different pair of switches and associated indicating lamp to facilitate stop selection, the surface layer otherwise having a "dead front" appearance.

Abstract:

A time-division switching system including first and second control units operating in accordance with a generic program is disclosed. After a new generic program is stored in the second control unit, the first control unit still operating in response to the old generic program initiates the performance of a test sequence by the second control unit. The first control unit times the execution of the test sequence. When the test sequence is not completed within a predetermined period of time or when test results generated by the test sequence do not match expected test results, a failure message is generated. Alternatively, when the test sequence is completed within the predetermined period of time and test results match the expected test results, a success message is generated.
