Patent GB-2246226-A (GB)
Title: Noxious fluid safety system
Inventor: CRATHORNE JOHN ROGER
IPC: F17D5/02
Filed: 1990-07-21
Abstract: The safety system detects and responds to a leakage of a noxious fluid, for example gaseous fuel, and comprises a detection unit 1 with a gaseous fuel detector which omits a signal when it detects a leakage, and an encoder which encodes the signal into a unique form and transmits the latter to an output of the detection unit. Operatively connected to the output is a control unit 5 including a decoder that checks and decodes a received encoded signal and then transmits to an output a signal for initiating the energisation of an electric motor coupled to a gaseous fuel flow control valve 9 in a main gaseous fuel supply line, the motor closing the valve on detection of a leakage. Resetting means allow the valve to be opened again. <IMAGE>

Title: Ergonomic remote control housing unit
Inventor: WEBSTER RAYMOND JOHN
IPC: H04B1/034
Filed: 1992-03-31
Abstract: The unit 1 has a curved base so that the fingers are in full contact with the unit and the thumb can fully oppose the fingers, thus reducing hand fatigue.

Patent GB-2263036-A (GB)
Title: Collision avoidance system
Inventor: KIKUCHI HAYATO
IPC: G01S17/931
Filed: 1992-12-29
Abstract: in estimating the relative speed between a vehicle and an obstacle, distance data relating to a plurality of possible obstacles are labelled, and present obstacle data are estimated on the basis of the past data. The estimated data are compared with actual data, thereby determining whether or not the new data corresponds to the same obstacle as the past data. If it is the same, the amount of variation in distance is determined for each obstacle by comparison of the past data and the present data; this is divided by a sampling time to provide a relative speed. Thus, noise (clutter) data can be eliminated to reliably provide a relative speed. The distance may be determined using a pulse video, the time of flight of the pulses giving distance (fig 7). <IMAGE>

Title: Colour error diffusion dependent on neighbouring pixel gradation
Inventor: KIM SEO-KYU
IPC: H04N1/52
Filed: 1993-11-22
Abstract: Error diffusion is used in a halftone processing system to remove errors introduced by inexact half-tone conversion of an input continuous tone colour signal. After RGB to CMY conversion the colour signal is in put to colour determining means 205, and the output half-tone colour signal is selected to have the smallest possible error; any error in the conversion is fed back to be added to the next pixel before conversion. The way in which colour determining means 205 is responsive to the input signal is dependent on the colour assigned to the previous pixel; this information is stored in neighbouring pixel colour information store 204, and influences the colour determining means 205 through error look-up table 203. By taking into account the colour or neighbouring pixels, the effects of ink bleed and overlap between adjacent dots can be obviated. The system may be calibrated for any printer using a colour standard and scanner. <IMAGE>
Patent GB-2272960-A (GB)
Title: Valve timing control apparatus
Inventor: TABATA TARO
IPC: F16D3/10
Filed: 1993-11-26
Abstract: Valve timing control apparatus decides an optimum timing of the valve from detected operating conditions, determines the present timing of the valve by detecting the phase difference of the camshaft from the crankshaft and decides a control value based on the present and optimum timing and the engine speed, thus causing the present timing to become the optimum timing. The apparatus may comprise a hydraulic system (Figs 3 and 4) driven by the engine, and engine speed related variations in hydraulic system performance may be offset by using engine speed to decide the control value. There may be provided means (5) for discriminating the direction (advance, retard) in which the valve timing is to be changed in order that the change of direction is reflected in deciding the control value. The apparatus may comprise an ECU 10 comprising a ROM, RAM, CPU and a spool valve control circuit (Fig 2). The control value may be a PID value computed using gains set according to engine speed. <IMAGE>

Title: Process for the preparation of items of laundry
Inventor: KRONER UDO
IPC: D06F93/00
Filed: 1995-09-19
Abstract: Soiled items of laundry (12) undergo pretreatment before being washed in laundries. In this arrangement, the items of laundry (12) received from various customers are checked and sorted according to type and degree of soiling. In order to automate the pretreatment it is proposed to transport the items of laundry (12) in a suspended manner along a conveying section (10) to check and sort the items in dependence on individual data assigned to each item of laundry (12). These data are retrieved at sorting locations (20, 21, 22, 23) arranged along the conveying section (10) and, thereupon, the items of laundry (12) are released from the conveying section (10) at the corresponding sorting location (20, 21, 22, 23) whereby automatic sorting of the items takes place in accordance with the washing treatment which is to be carried out in each case. <IMAGE>

Title: Viterbi trellis decoder reduces number of metric difference calculations
Inventor: GOLDING PAUL ADRIAN
IPC: H03M13/23
Filed: 1995-09-30
Abstract: The Viterbi state trellis (120) was Window Error Detection and effects two passes of a frame through the trellis (120). During a first pass, metric-difference calculations are suspended, but path metric calculations are indexed. At an identified branch, trellis data words (138-144) are recorded and associated with the branch. Upon completion of the first pass, a desired survivor path is determined and "traced-back" to its corresponding state in the identified branch using indexed path metrics, for example. The path metric corresponding to this state is nominally reloaded and, starting from that state, decoding of the frame occurs for a second pass while metric-difference (L-value) calculations are performed on the desired survivor path only, and only a single lowest L-value for the desired survivor path is recorded. This is intended to reduce memory space for the calculations and reduce power requirements. It may be used in GSM cellular communications using forward error correction.
