Patent GB-2162020-A (GB)
Title: Video processing systems
Inventor: TAYLOR RICHARD JOHN
IPC: H04N5/222
Filed: 1985-07-18
Abstract: A processing system includes a processor 10 and frame store 11. Both the frame store and processor are under the control of address mechanism 12. An incoming pixel is processed with previously stored information and the proportion of processed information restored is controlled to prevent errors in picture information density as a store location may be accessed a number of times in a frame period. The addressing mechanism 12 can generate the desired information from address information which is only provided on some of the store locations and which is only updated over more than one frame period. The mechanism includes spatial and temporal address interpolators to effect this operation. <IMAGE>

Patent GB-2183374-A (GB)
Title: Sequential access memory
Inventor: HILL IAN DAVID
IPC: G11C19/38
Filed: 1985-11-23
Abstract: The memory includes individual FET memory cells (R) (Figure 2) arranged in a matrix with a common set of column bit lines driven by transistors (PT1, PT2 ...) to prepare the cells for read or write. The rows of cells are selected by a pointer register (PR), a shift register in which a defined bit condition circulates to select the cells in the columns sequentially. The data input (IN) is offered to all cells in the first column, and the cells outputs and inputs are merged so that the whole device acts as a serial shift register. When a cell (e.g. R31) is selected for read-out, its neighbour (e.g. R21) is selected for write-in, the selection using the appropriate gate (e.g. G3) primed from the shift register. As a result of the merging of inputs and outputs a bit read from one cell goes to the cell in the next column therefrom and one up from the cell in the signal column. Thus the data is progressed through the array to the output (OUT). The output may be retimed to the clock original (Figure 4), with writing from the first column being to the row three places above. A filter frame store (Figures 6a, 6b), for echo cancellation may be provided. <IMAGE>

Patent GB-853219-A (GB)
Abstract: 853,219. Cushions. GOODYEAR TIRE & RUBBER CO. April 7, 1959 [May 2, 1958], No. 11695/59. Drawings to Specification. Class 52(4) [Also in Groups XXXII, XXXIII and XXXIV] Inflatable rubberized, fabric-reinforced loadbearing bodies, such as wheel tyres, cushions, airjacks, life rafts &c., are protected against the degrading effects of ionizing radiation by being inflated with an inert gas, preferably nitrogen, which is allowed to permeate into the rubberized fabric walls of the body in a radiation-free environment before the body is subjected to radiation. The use of inert gas as the inflating medium is said to obviate the degradation of the fabric caused by attack by oxidizing radicals or chemically active agents, such as ozone, produced by the ionizing effects of radiation on gases contained in the body. Suitable inert gases comprise the noble gases, with the exception of radon. Preferably, the inflatable body has any chemically active agents removed therefrom, either by evacuation, or by flushing with the inert gas prior to inflation therewith.

Patent GB-2202624-A (GB)
Title: Optimum biasing system for electronic devices
Inventor: POLYCHRONOPULOS DR BASIL
IPC: G01D3/02
Filed: 1987-03-23
Abstract: A biasing system is described which provides essentially total immunity against slow background fluctuations, coupled with excellent detection sensitivity for fast signals. Its principle is a control loop, based on an operational amplifier 15, which senses the output voltage of the device 10 and adjusts the bias applied to it via a network 16, so that it remains at a constant level, determined by the reference bias 14. The bias generating network 16 also acts as dynamic load and thus high stage gain can be achieved, yielding excellent sensitivity and S/N ratio. The control is made effective at low frequencies only, by including a low pass filter 13. Thus, high frequency signals are unaffected. The principle is illustrated with a photodiode circuit which provides immunity against extreme variations in ambient lighting conditions. <IMAGE>
