Title: Hybrid predictive coders and decoders for digital video signals
Inventor: WELLS NICHOLAS DOMINIC
IPC: G06T9/00
Filed: 1990-09-06
Abstract: In a coder for digital video signals, the difference between the ditigal video signals and prediction signals is subject to a transform prior to quantisation. In particular, a transform applied to the values of a block of pixels to produce sets of coefficients in the spatial frequency domain. A quantiser (14) acts on the coefficients to product a coded output which is decoded at a local decoder (18) operative on the coded output. The coder further includes means (20) for adding the prediction signal to the output of the local decoder (18) and a framestore (22) which receives the output of the adding means (20). A multiplier (26) multiplies the output of the framestore (22) by a factor slightly less than unity to form the prediction signal.

Title: Filter
Inventor: BUSCH-SORENSON THOMAS
IPC: B01D29/62
Filed: 1990-09-07
Abstract: A filter for filtration of photographic or reprographic developer comprises a filter cloth (40) arranged in a housing (38, 39) with an inlet (81) and an outlet (82). A field of standing waves produced by an acoustic transducer, (34) acts intermittently to clean the filter cloth. The filter cloth is arranged substantially in a pressure node, i.e. a velocity anti-node, of the acoustic field. As a result, a relatively inexpensive filter is provided which is economical to operate due to the long durability of the filter. In Figs 3, 5 a plurality of filter cloths are arranged, singly or in pairs, at different pressure nodes. The cloth may be backwashed at the same time as it is agitated by the acoustic field. <IMAGE>

Patent GB-920728-A (GB)
IPC: G03B7/00
Abstract: 920,728. Photographic cameras. KODAK Ltd. Sept. 7, 1961 [Sept. 9, 1960], No. 32152/61. Class 98 (1). In a photographic camera comprising a multispeed objective shutter having a shutter releasing member 8, a diaphragm adjusting ring 4 and a shutter speed setting ring 5 and in which the diaphragm aperture is adjusted automatically by photoelectric means upon adjusting the diaphragm adjusting means 4 to a predetermined position, a blocking member is moved by one or other of the said rings upon incorrect setting of the diaphragm adjusting ring and/or the shutter speed setting ring, to a position in which it prevents actuation of the shutter release member. As shown the blocking member comprises a rod 7 formed at one end with a shoulder 7b and pin 7a co-operating with camming surfaces 4a and 6a, formed on the diaphragm adjusting ring and the shutter speed setting ring respectively, to move a flag 7c in and out of the downward path of the shutter release member 8. The diaphragm aperture is set for automatic adjustment by aligning marks A and 12 on the diaphragm adjusting ring and the camera body respectively, causing the shoulder 7b to lie in the recess formed in the camming surface 4a so that the flag 7c lies in front of the downward path of the end 8a. If the shutter speed setting is set to B (bulb), however, Fig. 2 (not shown) the pin 7a rides up on the camming surface 6a pushing the flag 7c into the path of the shutter release member 8. The flag 7c will also be moved to obstruct the shutter release member 8 if the diaphragm adjusting ring is moved to bring mark 12 midway between mark A and the first manual setting i.e. 22, by the shoulder 7b riding up the sloping side of the recess in the camming surface 4a, Fig. 3 (not shown). Further clockwise movement of the diaphragm adjusting ring however cams the shoulder 7b out of the recess and forces the flag to the rear of the path of the shutter release member to allow manual operation of the shutter, Fig. 4 (not shown).

Title: Colour separation and contour correction of a ccd colour television camera output signal
Inventor: LIM JONG-GYUN
IPC: H04N1/409
Filed: 1993-02-22
Abstract: Colour separation and contour correction of a signal output from a Charged Coupled Device image sensor having the colour filter array of Fig 2 is effected by a circuit including two 1H (1 horizontal period) delay elements 1, 2. A chrominance signal delayed by delay elements 1 and 2 and a currently-input chrominance signal are added 3 thereafter to be decreased by half 4. Red and blue components Cr, Cb of the chrominance signals are derived from the chrominance signal from amplifier 4 and the 1H delayed chrominance signal from the delay element 1. Vertical 6 and horizontal 7 contour correcting signals are generated in response to the 1H delayed chrominance signal from the delay element 1 and the chrominance signal from the amplifier 4 and added 5 to the 1H delayed chrominance signal thereby to output a luminance signal which has been corrected in contour. <IMAGE>

Title: Time synchronisation between central and remote units
Inventor: GELLER HAIM
IPC: H04L7/04
Filed: 1993-05-28
Abstract: To provide an accurate time synchronisation between a real time clock (32) in a control unit (30) and an independent clock (52) in a remote unit (50), the control unit (30) establishes an event (42) common between itself and the remote unit (50) eg. by transmitting a synchronising sequence of code bits. The control unit (30) records a time at which the common event (42) occurs and communicates this time to the remote unit (50). The remote unit (50) synchronises its independent clock (52) to a current time of the real time clock by up-dating, at another instant in time, its independent dock (52) in response to the recorded time and a duration that has elapsed between the common event and the other instant. Applications include time synchronisation in SCADA systems, used eg. in a national electrical power grid. <IMAGE>

Title: Making resistance gas sensors.
Inventor: MCGEEHIN PETER
IPC: G08B17/00
Filed: 1993-06-15
Abstract: A resistance gas sensor which produces a significant resistance change on detecting low connotations of a gas such as carbon monoxide in air at ambient temperatures has a porous tin oxide zone containing a dispersion of precious metal on the surface of its pores. The sensor is made by impregnating porous tin oxide with a complex of precious metal salts, precipitating or co- precipitating the salts and heating the body to a temperature between the lowest decomposition temperature of the salt complex and at least 600 DEG C for a time sufficient to decompose the complex and deposit the precious metal. A heat treatment step, which may be the above step is performed at a temperature, and for a time which is an inverse function of that temperature so that the transducer resistance increases and, in the presence of a specific gas, in air at room temperature undergoes a specific reduction of resistance. A sensor for carbon monoxide showed a 50% resistance reduction to 95k OMEGA  in one minute in response to 200ppm carbon monoxide in air at room temperature. <IMAGE>
