Title: System for testing a data-processing unit
IPC: G06F11/22
Filed: 1974-03-15
Abstract: 1455078 Testing data processing systems COMPAGNIE HONEYWELL BULL 15 March 1974 [16 March 1973] 11756/74 Heading G4A In a testing system for a data processing unit initially a first bi-stable store M1 (Fig. 3) is set to an initial state by a manually operated circuit I, a test microprogram in an area Z of read-only store RO being then supplied to test circuits T to test the functional elements of the unit. As described the first sequence of microinstructions, the " initial setting " sequence, feed initial reference data to all the bi-stables of a second store M2, the store M2 then being connected to a detector E1 detecting errors occurring during test. The next sequence of microinstructions cause test data to be fed to the stores M1, M2 and if detector E1 detects a fault, a signal is fed on lead 13 to a unit DG to detect the location of the fault in question. This is effected by interrupting the current sequenc  of microinstructions to store the state of a register common to detectors E1, E2 (the latter activating circuit I automatically to initiate testing if a fault occurs during data processing) so that partial fault symptoms are collected and, when testing is completed, collated and displayed in a diagnosis phase. Test circuits.-The test circuits T include a register R1 of flip-flops b 1 -b 6 . The first b 1  permits connection and disconnection of the outputs of store M2 by controlling an And gate in circuit D1 linking the store to error detecting circuitry (e.g. parity checker F). Detectors E1, E2 are enabled by flip-flops b 4 , b 5  respectively. Flip-flop b 2  generates a signal OP1 at the end of test if the unit is operating correctly, this signal being fed to a second processor P2 and other members OG to indicate that the testing system is ready to process data. Two monitors C1, C2 controlled by flip-flops b 3 , b 6  are connected to the error detectors so that anomalies in the way the tests are carried out or in the operation of the detectors F may be found. The monitor C1 checks that the read-only memory is addressed in the zone Z and that the test is effected within a predetermined time interval (so that abnormal repeat of microinstructions may be detected).

Abstract: 1,090,904. Cathode - ray tube displays. ELLIOTT BROS. (LONDON) Ltd. March 16, 1965 [March 20, 1964], No. 11862/64. Heading H4T. [Also in Divisions B7 and G2] In an arrangement (see Division G2) wherein a semireflector (13), Fig. 3 (not shown), is disposed in the line of sight from a distant scene to an observer (14) so that a display on a cathoderay tube (15) appears to the observer (14) to be superimposed on a portion of the distant scene, means are provided for so moving the semi-reflector (13) that the display may be made to appear superimposed on another portion of the distant scene. Although the portion of the cathode-ray tube viewed as an image is thus maintained constant, the position of the image with respect to the outside scene is shifted and this may be compensated by feeding a signal from terminal (54), Fig. 9 (not shown), through a switch (53) to a summing amplifier (55) controlling the image position displayed in elevation by the cathode-ray tube (50), the switch (53) being closed whenever semi-reflector (52) is in one of its two pre-set positions. Alternatively, Fig. 10 (not shown), the signal controlling the position in elevation of the image displayed by the cathode-ray tube (50) is fed to a discriminator (60) which through relay (61) and servomotor (62) drives the semireflector (63) into its alternative position whenever the elevation signal exceeds a predetermined value, a switch (64) being simultaneously closed to feed a compensating signal to summing amplifier (65). In a further form, Fig. 11, instead of a two-position arrangement, a continuous servo-drive moves the semi-reflector. The output from feedback potentiometer 70 is added at 71 to the elevation signal, the sum being used (a) to operate the servomotor 72 and (b) to act as the elevation signal applied to deflection amplifier 73. The servo drive thus tends to null the elevation signal and the display remains central on cathode-ray tube 50 until the servo reaches its mechanical limit whereat electronic deflection takes over.
