Title: Digital-to-analogue converters
Inventor: CAIRNS GRAHAM ANDREW
IPC: G09G3/20
Filed: 1998-03-14
Abstract: A method of converting an input signal b(0) to b(3) to a corresponding analogue output voltage vp moves the output voltage from a first value to a second value, wherein the second value corresponds with the value of the digital input signal and the output voltage is moved from the first value to the second value in at least two steps. Capacitors 37 are selectivey charged during clock phase ck1. During clock phase ck2 charged from the three least significant capacitors is transferred to capacitor 41. During clock phase ck3 charge from the most significant capacitor 37 is transferred to capacitor 41. Capacitor 41 is partially discharged during clock phase ck4 and then fully discharged during clock phase ck1. The digital to analogue converter output may be fed to a liquid crystal display.

Title: Drive mechanism for an actuating cable
Inventor: CATRY PIERROT NOOL GERMAINE
IPC: F16C1/14
Filed: 1999-07-28
Abstract: A drive mechanism for use in tensioning the core of a Bowden cable comprises a casing (1) provided with recesses (20) for receiving the outer sheaths of Bowden cables, and a drum (9) upon which the Bowden cable is to be wound. The drum (9) is rotatable upon a portion (8) of a rotatable shaft that has an eccentric portion (10) upon which is mounted a gear wheel (11) having axially extending pegs (12) that engage loosely within apertures (13) in the gear wheel (9). In use the gear wheel (11) engages with an internal toothing (14) of the casing (1) and orbital motion transmitted thereto by the rotary shaft is accompanied by rotation of the gear wheel (11) at a rate determined by the relationship between the numbers of gear teeth on the internal toothing (14) and the gear wheel (11). Rotation of the gear wheel (11) is transmitted to the drum (9) via the pegs (12), and thus a substantial reduction is obtained between the rate of rotation of the rotary shaft and of the drum (9) mounted thereupon.

Title: Method of processing signals and apparatus for signal processing
Inventor: MCINTYRE JAMES HENDRIE
IPC: H04N11/06
Filed: 1999-07-30
Abstract: An image processing apparatus operates to process signal samples representative of at least part of a colour video image to produce legal colour signal samples representative of a legal colour version of the image. The apparatus comprises an over sampling processor which operates to generate an over sampled version of the input signal samples by generating at least one extra signal sample for each base input signal sample, an adjustment factor generator, which operates to generate a plurality of adjustment factors which when combined with the input signal samples have an effect of converting illegal colour pixels of the colour image into legal colour pixels, a colour legaliser coupled to the adjustment factor generator, which operates to combine the adjustment factors with the input signal samples to produce the legalised colour signal samples in an over sampled form, an anti-aliasing processor coupled to the colour legaliser, which operates to filter selectively the over sampled version of the legalised colour signal samples with an anti-aliasing filter in dependence upon whether the legalised colour signal samples have changed with respect to the input signal samples and if the legalised colour signal samples have not changed, bypassing the filter, and a decimating processor coupled to the colour legaliser which operates to decimate the filtered legalised colour signal samples to produce legalised signal samples having a sampling rate corresponding to that of the base input signal samples. The anti-aliasing processor filters the legalised colour signal samples by selecting the base legalised colour signal samples corresponding to the base input signal sample, where neither the base or the associated extra colour signal samples have changed with respect to the input signal samples.

IPC: B66F15/00
Filed: 1999-09-21
Abstract: A wheel lifting tool comprises a lifting arm assembly 1 positioned on one side of a pivot and a pressure plate assembly 2 on the other. An angled plate 6 forms the pivot 4 and receives the mounting shaft of the pressure plate assembly 2 which is pivotably attached thereto by means of swivel pins 3.

The lifting arm assembly 2 is positioned under the wheel to be lifted and downward pressure is then applied by means of the hand, knee or foot to the pressure plate, which lifts the wheel. For ease of storage, once the device has been used the pressure plate assembly may fold about a central hinge to be received between the arms of the lifting arm assembly.
Patent GB-2346013-A (GB)
Title: Calibration method for a phased array
Inventor: SUNDBERG MAGNUS
IPC: H01Q3/26
Filed: 1999-11-15
Abstract: A method of calibrating a phased array, having a number of signal paths (1 to 8) corresponding to the antennae of the array, comprises injecting a constant reference signal into one of the signal paths and then injecting calibration signals into the other paths and measuring the resultant signals in these paths. To calibrate the array the transfer function of the reference path is set to a predetermined value (Adj) and the transfer paths of the other paths are adjusted so that the same phase and amplitude relations exists between the reference path and each of the other paths. Preferably the paths of the phased array are connected at their feed ends to a lode shaping network (LSN) and the reference and calibration signals are injected by an adjustment unit (Cal.) having variable phase and amplitude adjustment. The signals may be injected into the paths either near the lode shaping network B, adjacent the antennae A or may be injected into the paths via remote radio coupling to the antenna C and the measurement of the resultant signals may also occur at any of these three locations. Preferably the calibration is improved by iterating the steps of the above method using different signal paths as the reference path and averaging over the resulting transfer functions.
