Title: Digital arithmetic circuit
Inventor: EVANS RICHARD ANTHONY
IPC: G06F11/14
Filed: 1995-09-11
Abstract: A digital arithmetic circuit (10) includes an inverting circuit (28) connected to a digital circuit (48) in which errors are to be detected. An operand input to the circuit (10) produces an output result in a first operation which is stored in a comparison circuit (82). The operand is inverted by the inverting circuit (28) on a second cycle of operation of the circuit (10) and the output result is compared by the comparison circuit (82) with that from the first operation. A non-zero result from the comparison indicates the occurrence of an error or errors in the operation of the circuit (10).

Title: Cordless telephone synchronisation for high speed high volume data transfer
Inventor: GUILLAUME BRADY N
IPC: H04B7/26
Filed: 1998-03-17
Abstract: A cordless telephone base unit (40 fig.2) generates, encodes and transmits a digital data burst having periodic transitions. A cordless handset 18 has a receiver 20 which samples the encoded data burst and a synchronisation device 30-36 for maintaining synchronisation between the receiver and the transmitted encoded data burst in accordance with a characteristic of an expected transition time of the digital data burst. The synchronisation device operates by comparing an actual time of transition to the expected time of transition and adjusting a sampling point of the encoded data burst by a one sided majority vote of samples around the sampling point. Thus minor time discrepancies between transmitter and receiver are compensated. The data is Manchester encoded into bit-pairs '10' or '01' and the receiver samples at four times the transmitted bit rate giving 8 samples '11110000' for a transmitted bit-pair '10'. The 8 samples are fed to synchronisation register 36 and bit slippage is detected if the two centre samples in the synchronisation register 36 match. The one sided majority vote test determines which direction slippage has occurred and the receiver sampling point is adjusted accordingly.

Title: SDH network
Inventor: ABBAS GHANI ABDUL MUTTALIB
IPC: H04Q11/04
Filed: 1998-08-21
Abstract: A method for the transmission of data in a synchronous digital hierarchy (SDH) network comprising the steps of transmitting to a node of the network a form of data signal from outside the network, converting the signal into a virtually concatenated information structure and transporting the signal through the network in the virtually concatenated information structure. For carrying out the method, tributary cards are arranged and configured to process signals received in contiguously concatenated form to convert them into virtually concatenated form for transfer across the network; thus providing for data transmitted in high-bandwidth, contiguously concatenated signals (ie VC-4-4c) to be transported across a SDH network, not itself capable of carrying contiguously concatenated signals.

Title: Sprayer/Spreader boom switching means
Inventor: CURTIS GEORGE SEYMOUR
IPC: A01B79/00
Filed: 1998-12-16
Abstract: Where agricultural sprayers and spreaders have their distributing nozzles and outlets located on transverse booms, problems arise when the projected track of the machine intersects that of a footpath crossing it if the angle of intersection lies other than at ninety degrees, since the said nozzles and outlets must needs be sequentially switched off, and then on again after the said path has been crossed, if the same is to be kept clear of the product being applied, or large areas be left untreated. The present invention outlines an electronic means of automating such sequential switching, and which same, by isolating the mechanism utilised for switching the said nozzles or outlets back on once the said path has been crossed, allows the same sequential switching means to be used at the beginning and ending of each bout of work, to switch the said nozzle or outlet means, or such pluralities thereof as may be grouped together, on or off, thereby diminishing waste incurred through over and under application of the product being applied, to the benefit of all.

Patent GB-2334480-A (GB)
Title: Displacing charge roller
Inventor: WIBBELS MARK
IPC: G03G15/02
Filed: 1999-02-01
Abstract: A charge roller displacement mechanism (30) prevents the build up of a sharply defined circumferential ring of contaminants on the surface of a charge roller (3) in an electrophotographic printing system, thereby reducing the severity of the print defect caused by the contaminants. By cyclically laterally displacing the charge roller (3) parallel to the longitudinal axis of a photoconductor drum (2) as the photoconductor drum (2) rotates, contaminants which reach the surface of the charge roller (3) will not form a sharply defined circumferential ring that interferes with the uniform charging of a photoconductor drum (2) charged by the charge roller (3). The charge roller displacement mechanism includes a first gear (31) that engages the gear (32) used to rotate paddles in a waste hopper of an electrophotographic printer cartridge (10). A second gear (34) engages the first gear (31) to provide a reduction of approximately 400 to 1. The charge roller (3) is forced against a face of the second gear (34) by a spring (35) or, alternatively, by angling the longitudinal axis of the charge roller (3) with respect to the longitudinal axis of the photoconductor drum (2). The face of the second gear (34) contacting the charge roller (3) includes cam (40). As the second gear (34) rotates, the charge roller (3) is laterally displaced across the surface of the photoconductor drum (2). The cam (40) is shaped so that one rotation of the second gear (34) corresponds to one cycle of displacement of the charge roller (3).
