Abstract: A multi-conductor cable tester and continuity analysis system having two groups of connector sockets wherein each group of connector sockets includes a plurality of different connector sockets designed to mate with the connector ends of the cable under test. An end of the multi-conductor cable is inserted into one cable socket from each socket group and the interconnection between the inserted cable ends is automatically determined by the system which interrogates each connected end of the cable separately, revealing unidirectional coupled data paths as may be provided with diodes or other electronic components. Additionally, the system compares the determined bi-directional continuity with previously stored cable continuity data corresponding to different, known cables and provides reference to one of the cables corresponding to the pre-stored cable data.

Abstract: This disclosure is concerned with simplifying the performance of musical compositions and the like by triggering the release of successive electronically stored coded data corresponding to the successive notes of the musical composition and in accordance with the rhythm thereof, and, upon such release, decoding the successive data to generate electrical oscillations which are then converted into corresponding audible tones of the notes of the composition.
