Title: Data processing system for scanning test points
IPC: H04Q3/545
Filed: 1975-01-30
Abstract: 1459714 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 30 Jan 1975 [7 Feb 1974] 4084/75 Heading H4K A last look scanner comprises a register for storing the previous conditions of a set of test points arranged in a matrix, the register being read and written in serial manner only. Changes in the condition of a test point are buffered and passed to a computer at the latter's investigation. If the buffer becomes overloaded, arrangements are made for retaining the previous condition (and not the new condition) of those test points whose changed condition cannot be recorded in the buffer. During each scan a (different) particular test point is examined upon computer instruction to check the correct operation of the scanner. The matrix of test points TPM e.g. line loop detectors, is addressed by a counter ACt having row a02, and column a03 address wires. The current condition of each point is recorded in a J-K flip-flop B and then clocked into the first stage of a shift register SR16. At the same time the previous condition of the point is removed from the last stage of the register and compared with the present condition in Exclusive OR gate EO. If a change has occurred, an up-down counter UDC is stepped so as to address the next free row in a buffer ME, a local control circuit CC is alerted to pass a write signal to the buffer and the contents of row REG1 of the buffer are recorded in the free row. REG1 contains all the information e.g. address, pertaining to the test point on which the scanner is currently standing. At the end of the scan, the computer CPU reads out the buffer (the UDC counter being decremented to provide an indication as to how many rows of buffers contain change information) and then indicates a new scan. An additional counter HCt is used for nominating a test point for checking purposes. When the address counter ACt reaches the address in HCt during the course of a scan, the current condition of the nominated test point is recorded in the buffer irrespective of whether a change has occurred. The CPU knows what the condition of this point should be so that an error in scanner operation is immediately detectable. If, during a particularly busy period, the buffer is filled-up, the output of the shift register SR16 is recirculated via AND1 so as to ensure that any change occurring during the overload period is not lost. (This would occur if a test point changes its condition and the new condition is stored in SR16 in place of the old condition. The change can then be detected during the next scan). If a check test point's data cannot be recorded due to overload, the counter HCt may be stopped at the same position during the next succeeding scan.

Abstract: 1,128,882. Time-control of magnetic recording. INTERNATIONAL STANDARD ELECTRIC CORP. 27 Jan., 1967 [29 Jan., 1966], No. 4170/67. Heading G5R. In apparatus for controlling the rate of flow of information in a train of intelligence signals in the course of being stored on or reproduced from a recording medium, with the aid of a simultaneously or previously stored periodic electric pilot or like signal, the pilot or like signal is split into a delayed and a non-delayed signal, and both these signals are superposed in a phase- or phase-and-frequency comparison circuit for generating a voltage to be used for controlling the rate of information flow; the recording medium is influenced magnetically or otherwise, during relative movement between it and a recording or reproducing element. In the simplest embodiment (Fig. 1, not shown), reproduced pilot, synchronizing and/or subcarrier signals are derived at the output (2) of the read-out head (1) of a storage device, and are split up between a direct path, extending to input (4), and an indirect path via a timedelay arrangement (3) extending to input (5), of a phase-, or phase- and frequency-comparison circuit (6). At the output (7) of this circuit a control voltage is available as a function of the phase or frequency difference, to be used to correct and stabilize the speed of the information flow, e.g. by varying the driving speed of the recording material and/or the recording or read-out head. In Fig. 2 (not shown), the delay arrangement is omitted, but a second read-out head is provided downstream (in relation to recording- material travel) of head (1). Each head is connected directly to one of the two inputs of comparison circuit (6). As shown in Fig. 3, recording head 1 is connected via time-delay arrangement 3, and readout head 8 is connected directly, to comparison circuit 6. The train of signals stored by head 1 on a moving record medium is led in direction 9. The absolute speed of the information flow may be regulated because the transit time of the signal recorded via head 1 up to read-out head 2, and the transit time through the time-delay arrangement 3 are compared with one another, as indicated by the double-headed arrow at 2.
