Abstract: 1409666 Alarm systems NAC Inc 11 Sept 1972 [9 Dec 1971 20 Jan 1972 4 May 1972] 42146/72 Heading G4N Changes in a pattern under surveillance are detected by: monitoring the pattern with a TV camera; sampling an area of the pattern by sampling the monitor video output signal by vertical and horizontal gating signals; integrating and storing the video signal during one sample period; similarly sampling the same area at a later time; comparing the integrated signals of the two samples; and producing an output signal if they differ by more than a predetermined amount. The comparisons are made repetitively, and in order to avoid the production of false output signals, the stored signal is updated periodically, by storing the second sample of one comparison and using it as the first sample of a subsequent comparison. The arrangement may be used to detect intruders or fines, and a number of monitors may be sequentially fed into the system. As described, the vertical and horizontal gating pulses define nine sample areas which may be adjusted in size and in position in the monitored area. For example in an art gallery the samples may be adjusted to correspond with valuable paintings. The integrated signals of the samples are fed to A/D converters and the storing and comparison is carried out on the resulting digital signals.

In a quadruple piversity combining system the first pair of modulated radio signals being modulated about one centre frequency and the other pair about a second centre frequency, the signals of the respective pairs are adde linearly before detection, and after detection the two combined signals are added linearly to form a single output. The four signals are applied at 5, 6, 7, 8 over frequency changing paths 1-4 giving I.F's of F1, F2, F1, F2, respectively, the paths 1, 2 and 3, 4 being paired and their outputs fed to common I.F. amplifiers 9, 10. The two I.F. outputs F1, F2 of each amplifier 9, 10 are filtered out in filters 30, 31, 32, 33, the two F1 outputs and the two F2 outputs being applied to respective linear adding networks 34, 35. Before addition, the I.F. signal pairs F1, F2 which are assumed to be frequency or phase modulated, are rendered in phase by phase comparators 37, 36 the outputs of which control the frequency of the local oscillators 22, 18 respectively, in the frequency changing paths 3, 2. The adder outputs are passed via linear limiters 38a, 40 and 39, 41 to respective discriminators 42, 43, the outputs of which are added at 44 to give the final output. A.G.C., derived from an A.G.C. detector 38 fed from network 35, is applied to the I.F. amplifiers 9, 10 in order to ensure that the signals applied to the linear adding networks are amplified equally. The A.G.C. control voltage is proportional to the amplitude of the combined signal at the frequency F2. The diversity signals may be derived from spaced aerials or by employing different polarization of the receiving aerials. Specification 904,069 is referred to.
