Patent GB-2144246-A (GB)
Title: Proving safe operation
Inventor: BROWN CHRISTOPHER ROBERT
IPC: B61L1/20
Filed: 1984-07-26
Abstract: To prove safe operations of a conventional computer based system the processing hardware is multiplied in parallel channels and the individual results cross-correlated to determine the correct result. The proposed arrangement aims to achieve a comparable level of safety using a single processor channel operating cyclically by correlating results computed during different operating cycles. The processor is also checked frequently, preferably during each cycle to guard against processor faults. The cyclic redundancy approach is then able to disqualify results arising from common mode interference and spurious errors in the processor inputs. <IMAGE>

Title: Hologram manufacture
Inventor: ANDREASSSEN JON
IPC: G03H1/08
Filed: 1986-12-09
Abstract: For the manufacture of a hologram, particularly one comprising a space-variant optical interconnect, a reference beam (18) and an object beam (21) are formed from a laser beam output from a source (15), the object beam portion of the laser beam being directed through an optical fibre (20) monomode at the laser beam wavelength and the output end of which acts as a point source. The object beam and reference beam intersect and are incident on a holographic recording medium (1). To ensure each area of the medium is exposed only once when providing an array of hologram elements a masking arrangement (13, 14) is used. The position of the output end of the fibre and the relative position of the aperture (14) of the mask (13) and the medium (11) is changed between exposures. The movement of the fibre end and the masking arrangement may be computer controlled thus facilitating hologram manufacture. <IMAGE>

Title: Crosslinked gels based on glycol esters of methacrylic acid with enhanced swelling capacity in water and a method for producing them
Inventor: SULC JIRI

Abstract: Articles, such as contact lenses, made from 2-hydroxyethyl methacrylate copolymer gels, which are crosslinked with up to 2% by weight of ethylene glycol dimethacrylate, are swelled with an aqueous alkaline agent e.g. hydroxide and moderately heated until the covalent network is reorganized by interruption of the stretched cross-links and formation of new cross-links. After washing off the hydroxide with water, the swelling capacity is substantially higher than the original swelling capacity of about 40%.
Patent GB-2187311-A (GB)
Title: Automatic vehicle speed control system
Inventor: BLEE TIMOTHY JOHN
IPC: B60K31/18
Filed: 1987-03-24
Abstract: The system comprises a main memory which stores a signal Vr representing desired road speed which is compared with a signal Vs representing actual speed. An actuator responds to any error by adjusting the engine to bring the vehicle to the correct speed. The driver can switch into the main memory either one of two preset desired speed values from a store. He can also modify these preset values in the store by feeding in, instead, the actual road speed of the vehicle, such modified preset values remaining until the engine is next switched off. Units enable the driver to increment or decrement the stored desired speed by small amounts (e.g. 0.5 miles per hour, 0.8 kilometres per hour). The system incorporates a "SOFT OFF" feature, by which, under certain switch off modes of the system, the engine power is not immediately shut off abruptly but at a controlled rate. The system is advantageously implemented by means of a microprocessor. The stored parameters can be arranged to be overwritten by alternative parameters stored in an EPROM. The driver can also select acceleration or deceleration at a predetermined rate.

Title: Automatically identifying coupon shipment irregularities
Inventor: MARSHALL ROBERT
IPC: G06Q30/02
Filed: 1987-04-07
Abstract: Shipments of discount coupons are subjected to automated statistical analysis to identify coupon shipment parametric abnormalities. Allowable ranges for preselected coupon shipment data characteristics are established and are automatically updated. Those coupon shipments that exhibit parametric abnormalities are segregated for further review and evaluation. An operational knowledge base 46 stores data characteristics of interest associated with a plurality of previously processed coupon shipments from a plurality of retail stores and used as an information base to statistically derive, 50, the allowable ranges against which the data characteristics of new coupon shipments are compared, 54. Periodically, at least a portion of the information stored in the operational knowledge base 46 is replaced with data characteristics associated with more recently processed coupon shipments. Ultimately, a decision is made, 56, either to pay the submitting retail stores for their coupon shipments or to deny payment or to refer the payment decision to the involved manufacturers. In addition, the information identified may be used to provide extensive financial and marketing information services.

Patent GB-2221110-A (GB)
Title: FM oscillator
Inventor: HAWKES HENRY WILLIAM
IPC: H03C3/09
Filed: 1988-07-05
Abstract: An FM oscillator having an output of low phase-noise content, primarily for sub-carrier generation, is obtained by providing an FM oscillator 1 and a CW reference oscillator 2, the latter having an output frequency close to the centre frequency of the former but having a substantially lower total noise content close to its output frequency. The two outputs are multiplied together in a multiplier 3, and by means of filter 5, 6, there is selected from the product a component comprising the zero-order Bessel Function of the modulation index of the FM oscillator multiplied by a function of the difference between the total noise in the two oscillator outputs. This component is combined with the FM oscillator output to produce an output having the centre frequency of the CW oscillator, which is frequency-modulated at the modulating frequency of the FM oscillator and which has the total noise content of the CW oscillator close to the centre frequency. Preferably the centre frequency of the FM oscillator is converted to the output frequency of the CW oscillator in a phase-lock loop 1, 3, 8, before multiplication with the CW oscillator output and the above combination is effected by applying the above selected component to phase-modulate, 10, the thus-converted FM oscillator output. The phase 10 can be replaced by a single side band generator (7, Fig 1). <IMAGE>
