Title: Scan converter

Abstract: 1494899 Television HUGHES AIRCRAFT CO 3 Dec 1974 [3 Dec 1973] 52292/74 Heading H4F Scan converter for changing low time base (slow scan) parallel channel video data into single channel high time base video data of a television format, comprises a plurality of storage devices (e.g. recirculating shift registers) into selected ones of which the applied parallel channel data is stored, these storage devices being sequentially read out in accordance with a television format, e.g. each recorded line of video signal from each channel is read out a number of lines and at a faster time base rate. In a first embodiment two infra-red detectors 10A and 10B, Figs. 1-3, each producing output signals A and B corresponding to 60 line scans per image field are fed via A/D converters 20 and 22 and suitable logic 24 to a digital memory device 26. In operation the simultaneous IR scanner video scan line outputs A 1  and B 1  having a period of 254 Ásecs. are stored in registers 1 and 2 in memory 26. The second horizontal scan period data lines A 3  and B 3  are then stored in registers 3 and 4 while at the same time the signal A 1  and the signal B 1  are each read out twice at a faster rate (see Fig. 3) so that during the 254 Ásecs. period (4 x 63À5 Ásec.) an output comprising A 1  A 1  B, B 1  is produced that is D/A converted 30 and combined 46 with television synchronizing information to produce a composite television format video signal. This process is continued for the first field scan (Fig. 3) and then repeated for the second field scan, these fields being displayed on a television monitor in interlaced manner (Fig. 2) so that with a stationary scene, each line thereof is converted into four adjacent identical lines on the display. A scan converter for four parallel channels is described with reference to Fig. 4 (not shown), the four channels being the outputs from four detectors associated with an IR rotating drum scanner the adjacent mirror facets of which shift the IR image by 8 scan lines. Each detector scan line output is stored in one of eight shift registers from which it is read out three times, and since the lines scanned by the detectors during successive frames are effectively interleaved each line is converted into only three adjacent identical lines on the display (Fig. 5, not shown), the storage and read-out sequence being as shown in Fig. 6. An embodiment which is similar to that of Figs 1-3 but which operates with analogue video samples instead of digital samples is described with reference to Fig. 18 (not shown), the recirculating shift registers being replaced by charge transfer/ storage circuitry.
Patent GB-1449191-A (GB)
Title: Automatic focusing device
IPC: G03B13/36
Filed: 1973-11-14
Abstract: 1449191 Automatic focussing ASAHI KOGAKU KOGYO KK 14 Nov 1973 [30 Nov 1972] 52836/73 Heading H4D An automatic focussing device for use in image forming optical apparatus, e.g. a photographic camera comprises a means to adjust the focus which is depended on a signal derived from the contrast of the image, the optical path to which image having a diffraction grating positioned therein, and a mechanism for scanning the image. The diffraction grating 1 acts effectively as a band-pass filter which rejects lower frequency spatial variations in intensity across the image, so that the signal derived is closely dependent on the resolution of close detail. In other words, the Optical Transfer Function of the system is improved. In Fig. 4, r 0  and r 1  represent the O.T.F. or image power spectrum without a phase grating in position, when focussed and unfocussed respectively and the triangular functions A 3 H 0 A 4 , A 3 H 1 A 4 , each plus function OA 1 A 2 , represent the respective spectral distribution when the grating is in position, the maximum H 0  occurring in the in-focus position. The object image, so filtered, is scanned by a moving slit 6 such as a rotating slit disc, with a higher O.T.F. cut-off frequency than the filtered object image. The scanned image is condensed in lens 7 and detected by a photo electric detector 8, placed in simple harmonic motion by an oscillator 12 driving a vibrator 14, so that the optical path length is modulated. The detection signal is thus sinusordally modulated, and amplified at 9, whereafter the low frequency component thereof, corresponding to function OA 1 A 2 , is removed by high pass filter 10. The output signal level is v, therefrom (Fig. 8) is maximised at focus, but the optical path length modulation has a phase shift of # between positive e 1  and negative e 2  defocusing, which phase difference is detected by phase detector 11. The polarity of the D.C. output voltage from the phase detector, corresponds to whether the system is positively or negatively defocused, which voltage is applied to a D.C. servo motor which drives lens focussing mechanism 17, 18, thereby focussing on the image. The position of the grating 1 is variable by means of shifter 20, actuated by push button 19 along the optical path, (varying distance b), so that the signal V is maximised, for a particular object to be shot. Voltmeter 15 displays the value of V which is to be maximised. In other embodiments (Fig. 9, not shown) the slit (24) incorporates a scanning mirror (23), is stationary and the optical path between grating and detector which oscillates the beam across the slit. The mirror may be replaced by a rotatable prism.

Abstract: 1526960 Automatic exchange systems INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1975 [30 Dec 1974 (5) 26 June 1975] 52959/75 Heading H4K The communications network described in US Specification 4,009,343, includes a management processor for evaluating and controlling the operational effectiveness of traffic connections within the network. The system comprises a plurality of branch exchanges 1À1-1À3, 2À1-2À3, 3À1-3À3, Fig. 1 arranged in geographical groups, each group being connected to a respective network access unit 1-3 of a geostationary satellite communications facility. Each of the branch exchanges and access units include a stored programmed processor with microprocessors being used for the branch exchanges. Digital TDM trunks employing voice activity compression (VAC) interconnect the branch exchanges and the area network access unit. Both duplex telephone lines and data links are served by the system. For other details not relevant to the current invention reference is directed to the above Specification. The management processor NMF referenced 40 in Fig. 8 is connected via a link 41, e.g. a leased public telephone line, to the input of at least one of the branch exchanges 10, the insert also being connected to the processor 34 of the exchanges. Each of the other branch exchanges also have a connection 42 between the processor 34 and the duplex line side of the switching network. Information is transferred directly between the NMF and its local branch exchange processor 34 via the link 41. Information for the network access unit (NAU) processor 12 associated with this branch exchange is transmitted first to the processor 34 and then via the signalling channel 0 of the digital trunk 10À1 to the NAU processor 12. For other geographical areas a normal traffic connection is established between the NMF port and a branch exchange of the remote area, the path including "bootstrap" link 42. Information for the NAU processor of a remote area is relayed via one of its branch exchange processors which sends on the information over the signalling channel of the digital trunk. System initialization for satellite acquisition and for basic traffic connection operations can be achieved in processors 12 of the NAU's using local storage discs and the branch exchange processors are provided with resident microprograms. The NMF is then able to establish connections with all the processors of the system to load programs and tables relating to routing within the system. During normal operation the NMF acts passively and receives from the processors statistics relating to call blocking, freezeout ratio on the digital trunks due to VAC, and call timing information which is used for call billing and for appraisal of network utilization by subscribers. When the statistical reports indicate unusual operation, the NMF may reconfigure the system by reloading the routing information tables in the processors 34,12. In response to excessive freezeout ratio the NMF can instruct any one of the branch exchanges to restrict the number of trunk connections therefrom.
