Title: Compressed refresh buffer
IPC: G09G1/16
Filed: 1975-11-28
Abstract: 1488538 Image display arrangement INTERNATIONAL BUSINESS MACHINES CORP 28 Nov 1975 48944/75 Heading H4F The bit storage of refresh circuitry used for digital image display (e.g. the display of a printed page or map on a CRT 1 or electroluminescent device pulsed array) is reduced by considering the image to be displayed as a number of equal digital image areas and storing in a buffer store 4 only those digital image areas which do not contain only bits of a given value (e.g. only areas I and III), a bit map store 9 being provided which contains for each digital image area a bit the value of which indicates whether or not the digital image area consists only of bits of a given value (e.g. the bit map stored comprises 101 for the example of Fig. 2). During display the contents of the bit map store 9 are read and in response thereto either the appropriate contents of the buffer store 4 are read or bits of the given value (e.g. for area II) are generated. If read-out from store 4 is non-destructive the connection between output and input shift registers 5 and 6 is not required. Addressing circuitry 8 of store 4 is a counter which increments by one storage location address after each access. A store 12 for part of the image is provided to enable the bit map store 9 to be loaded with the aid of OR circuit 13. When store 9 is loaded the image is again read out of store 12 and buffer store 4 loaded in dependence upon the stored bit map. Certain of the displayed objects may be caused to flash on the CRT display by providing an additional buffer store (15, Fig. 5, not shown) and an additional bit map store (19) both addressed by a timing generator (21). The store 4 may be subdivided so that quarter images are stored (Fig. 6, not shown). If each image point is defined by more than one bit, each such bit is defined as belonging to a different digital image, e.g. the choice of seven colours or blank can be represented by three bits and thus three digital images are stored in separate buffer stores. Alternatively two different intensity images may be stored in store 4, register 5 and bit map store 9 being duplicated.

Abstract: 1,153,913. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 2 Nov., 1967 [8 Nov., 1966], No. 49890/67. Heading H4K. Single cross-bar switches are worked in separate sections to simulate an aggregation of smaller switches so as to gain the advantage of the smaller cost per cross-point of larger switches. As seen in Fig. 2 the horizontal multiples of a cross-bar switch are split to form two stages the first stage serving subscribers and the second stage giving access to local junctors OW and outgoing/incoming junctors FW. The verticals are split into a number of sections each section serving a subscriber's group such as A1, A2, in the first stage (only two sections being shown) and each section in the second stage serving a group of junctor terminals. The vertical sections in the first stage are linked to the sections, not necessarily equal in number, of the second stage so as to give full access from each subscriber to all junctors. If a path is required involving a vertical that is already occupied, the existing path can be transferred to auxiliary unbroken verticals such as K1, K2 coupled through the marker instead of over the interstage trunking. The marker is then able to operate select bars for the transferred existing connection and for the new connection so as to set up both paths and hold them on the same vertical while the by-path through the marker is released.

Abstract: 1530264 Indicating measurement HONEYWELL Ltd 26 Nov 1975 [27 Nov 1974] 51325/74 Heading G1J [Also in Divisions G4 and H3] A bar display system for indicating as a bar of light the magnitude of a quantity represented by an electrical input signal includes circuitry to produce scale marks as bright lines spaced along the bar of light. The system includes a bar display device 10 in the form of a flat bar-like gas-filled space having a transparent anode 11 on its inner front face and 200 equally spaced cathodes 12 on the back face, the cathodes being connected in three inter-digitated sets 13, 14, 15. A clock signal generator 20 drives a display drive circuit 21 for energizing each set of cathodes in sequence. A "keep-alive" anode 18 and cathode 17, and a reset cathode 16 are provided at one end of the space. A ramp signal generator 30 driven by the clock signal generator 20 supplies a ramp signal to a comparator 31 where it is compared with the input signal from 32. The comparator 31 feeds an anode drive circuit 33 which maintains the anode 11 energized while the ramp signal is less than the input signal, but de-energizes the anode when the ramp signal exceeds the input signal, to extinguish the visible discharge, and give a length of the bar of light proportional to the magnitude of the input signal. A divide-by-200 circuit 22, 23 sends a reset pulse to the ramp signal generator 30 and the display drive circuit 21 once per 200 pulses from the clock signal generator 20. The divide-by-200 circuit comprises a divide by-5 unit 22 and a divide-by-40 unit 23, the output of unit 22 also driving a one-shot circuit 24 controlling an output gate 25 of the clock 20. After every five pulses from the clock, there is thus a dwell before the pulses recommence, this dwell causing each 5th cathode 12 to be engergized for a longer time, and thus to be brighter than its neighbours.
