Title: Reliability checking system for data sensing
IPC: G06F3/06
Filed: 1963-06-11
Abstract: 1,013,841. Sensing perforated records. SPERRY RAND CORPORATION. June 11, 1963 [June 14, 1962], No. 23172/63. Heading G4M. [Also in Division H3] Tests are made to determine whether or not the various components of a perforated-record reader are functioning correctly at intervals when no information is being sensed. Each column position on a record is sensed by a corresponding photo-cell 16. When a perforation is present, cell 16 renders transistor 31 conductive, and, resistor 36 being of greater magnitude than resistor 37, a positive read pulse applied from generator 38 produces little change in potential at collector 33 and trigger 23 remains in its " 1 " condition. If no perforation is present, transistor 31 does not conduct and trigger 23 is switched to its " 0 " condition by the pulse from generator 38. A first test is made during the space between cards 15 or at a special, " all-perforated " column in the case of a tape. A positive pulse of greater amplitude than the read pulse is applied at terminal 71, and if insufficient light is falling on cell 16, or transistor 31 is not conducting properly, trigger 23 is switched to the " 0 " condition to give an alarm. A further test is made when a non-perforated part of the record is passing cells 16. If a short exists between the collector and emitter of transistor 31, a pulse from generator 38 will not set trigger 23 to the " 0 " condition and again an alarm is signalled. Trigger 23 is reset by pulses applied to terminal 76.
