Title: Vehicle signal relay device
Inventor: JOHNSTONE MARTIN M
IPC: B60Q1/30
Filed: 1995-05-12
Abstract: There is described a device that enables the signal of a vehicle to be relayed to a position where the signal is apparent to following traffic. The device is of particular utility where a car is fitted with a rear bicycle rack or where the electrical connections to a trailer, etc. have not been made. The device comprises a light detection means attached to or near a rear indicator of the vehicle. When the vehicle indicator is switched on, the indicator light is detected by the light detection means which then generates a signal. The signal generated may be, for example, a corresponding light indicator in a trailer board. Optionally an external power source may be accessed by the device and is preferably the battery of the vehicle. The light detection means may be an optical fiber. <IMAGE>

Title: A liner for a well
Inventor: DIXON ROGER ALLAN
IPC: F16L21/08
Filed: 1996-07-03
Abstract: The liner (1) avoids collapse due to settlement loads by having tubular lining sections insertable one (2) inside another (3) with coupling means comprising an expanding ring (28) locating in a deeper groove (27) of the first section (2) during insertion, moving into shallower groove (25) to inhibit separation by abutting against a shoulder of groove (36) in the second section (3), but is compressible back into deeper groove (27) to allow telescoping. A limiting means such as shear-off pins or a welded ring element (60) limits initial insertion, the limiting means being overcome by longitudinal settlement loads applied to the liner.

Title: Fluid level sensor has signal paths of different lengths
Inventor: BROWN RICHARD HUNTER
IPC: G01F23/296
Filed: 1997-04-30
Abstract: Device 1 for determining the level of fluid 14 within a vessel comprises a plurality of sets of acoustic transmitting and receiving devices such as piezoelectric devices 6a-6f spaced along the vessel. The transmitters simultaneously generate an acoustic signal, to be reflected from a stepped reflector plate 10 for reception, only for those signal paths which pass through the fluid. The stepped reflector provides different signal path lengths between each transmitter and receiver, thereby providing a time delay between the returning signals so that different fluid levels can be measured. Circuitry is provided (figs. 18 & 19) to balance the amplitude of the response signals. The required number of connection pins, and hence the cost of manufacture, is reduced. Alternative arrangements for providing different acoustic path lengths are shown (figs. 5, 10, 12 & 13).
Patent GB-2317079-A (GB)
Title: Estimating timing and frequency offsets for synchronous communication in an interference environment
Inventor: TAYLO DANIEL RICHARD
IPC: H04B7/208
Filed: 1997-07-31
Abstract: A communication system 100 includes satellites 102,104 and a mobile exchange unit (MXU) 120 for exchanging communication information to users. A satellite 102 generates synchronous timing frames requiring users operating through the MXU to anticipate timing and frequency requirements to participate in communications. The MXU must advance transmissions to a satellite 102 to ensure that transmissions arrive at satellite 102 within the proper synchronous receive window. Such advanced transmissions by the MXU can interfere with the reception of ring alert/page transmissions 130 which contain the present location of the transmitting satellite 102. Co-located transceivers (310, fig.3), within the MXU, must monitor the ring alert/page transmissions while not in use to determine location estimations for the generation of timing and frequency offset estimates for initiating a communication link. When interference is detected on the ring alert/page transmission signal, provided one of the MXU's transceivers is in use, the MXU may extract and distribute timing and frequency offset parameters from the active transceiver (310).

Title: Secondary seal bypass valve for gate valves
Inventor: WAFER DONALD B
IPC: F16K43/00
Filed: 1997-09-22
Abstract: A gate valve comprises a stem 34 movably supported in a bonnet 28. Inboard 50 and outboard 52 seals between the stem 34 and the bonnet 28 prevent pressurized fluid within the valve from escaping through the bonnet 28. A bypass valve 70, when open, allows fluid to bypass the inboard seal 50 and be contained primarily by the outboard seal 52. When closed valve 70 allows fluid to be contained primarily by the inboard seal 50. In normal operation, the bypass valve may be left open to permit the outboard seal 52 to function as the primary seal. When outboard seal 52 develops a leak, bypass valve 70 may be closed so that the inboard seal 50 becomes the primary seal. If desired, the gate valve can continue to be operated with the inboard seal 50 functioning as the primary seal. Alternatively, the outboard seal may be replaced. During replacement, the inboard seal 50 prevents pressurized fluid from leaking out without the need to backseat the valve.

Title: Addressing a ferroelectric liquid crystal display
Inventor: ROBINSON MICHAEL GERAINT
IPC: G02F1/133
Filed: 1997-10-16
Abstract: A liquid crystal device comprises a group of first and second strobe electrodes (S i , S i+1 ) and a plurality of pairs of data electrodes (3a, 3b) which cross the first and second strobe electrodes to define first and second pixels. Each pair of data electrodes comprises a plurality of elongated parallel first electrode portions (3a) interdigitated with the second electrode portions (3b). The display device has a data voltage source (29) for applying one of N data voltages to the first data electrode and simultaneously applying one of N data voltages to the second data electrode, so that it is possible to apply M different combinations of data voltages to the two column electrodes defining a column of pixels. M is thus greater than N. This arrangement allows two rows of pixels to be driven simultaneously whilst requiring the data voltage source to provide fewer different operating voltage levels. Other advantages are that by driving several strobe electrodes at the same time the refresh rate of the display can be increased, and all possible combinations of activated display elements can be implemented.

Title: A context based coding/decoding method and apparatus
Inventor: CHO SUNG-RYUL
IPC: H04N7/26
Filed: 1998-01-20
Abstract: An apparatus encodes a binary shape signal by using a modified context-based arithmetic encoding technique. The apparatus computes a context number of each binary pixel 120 in the binary shape signal based on its corresponding context. Then, a probability corresponding to the context number is detected and a state of each binary pixel is determined by comparing the probability with a preset threshold value 130. Furthermore, a predicted pixel value corresponding to each binary pixel is decided based on the probability. The predicted pixel value is compared with an original pixel value of each binary pixel to thereby output a mapping value representing whether the predicted pixel value is identical to the original pixel value or not 140. The apparatus generates a first and a second sequences by rearranging the mapping values of the binary pixels in the binary shape signal according to the states of the binary pixels 150 and assigns adaptive probability sets 160 to the first and the second sequences, respectively. The first and the second sequences are arithmetically encoded base 170 on the adaptive probability sets to thereby produce an encoded binary shape signal.

Title: Receiver with feedback subtraction of unwanted signals to control bandwidth
Inventor: TOLSON NIGEL JAMES
IPC: H04B1/26
Filed: 1998-11-07
Abstract: Multiple loop feedback is applied to broadband IF heterodyne or direct conversion radio receivers. Unwanted products from the output of the second down conversion mixer (6) are filtered out (10,11), restored to IF frequency (12) phase shifted (13) and added at the IF frequency to one or more inputs of the second mixer to cancel the unwanted products and linearize the mixer. When the feedback is applied to a single input of the mixer, it is added via two signal paths e.g. two summing junctions. By adding the feedback at the IF frequency via more than one signal path the relatively high gain required is achieved without introducing a large DC offset. In direct conversion receivers the unwanted output signals from the mixer are added in antiphase to one or more RF inputs of the mixer via two feedback loops.
