Patent GB-2300505-A (GB)
Title: Programmable logic with parallel and serial user interfaces
Inventor: KEAN THOMAS A
IPC: H03K19/177
Filed: 1996-05-01
Abstract: A configuration structure for a field programmable gate array (FPGA) allows a user to reconfigure or partly reconfigure the FPGA from within the FPGA, allows an addressable configuration memory 38 to be addressed in parallel through a set of address and data lines or through a serial interface. Signals such as chip-enable and other control signals can be modified by user logic 39 so that data loaded through a serial interface pin is entered into an addressed portion of configuration memory. The configuration memory programs not only the internal circuitry accessed by the user but also a programmable switch 34 for directing signals between external pins 31, configuration memory control lines, and a serial data interface. Providing both parallel and serial interfaces allows a programmable switch which is initially configured to connect its related pad or pads to configuration control lines such as a chip enable line or a serial data input line to later be configured to connect an internally generated signal or signals to the line or lines and thus override any external signal which would have been connected to that line or lines.

Patent GB-2315626-A (GB)
Title: Amplified optical network
Inventor: KIRKBY PAUL ANTHONY
IPC: H04B10/272
Filed: 1996-07-20
Abstract: An optical network in which there is upstream communication of traffic from a set of outstations (11) to a basestation (10) via a net of transmission pathways that includes an active optical combiner (26). This combiner has a set of n input ports (30) coupled to a single output port (34) via the series combination of a single opto-elecronic transducer (31), a electrical amplifier (32), and an electro-optic transducer (33). The coupling from the input ports to the opto-electronic transducer is multimode in order to avoid the combining loss of a single mode combiner. If short enough, the individual transmission paths from the outstations to the combiner may also be multimode, with a consequent potential for saving in outstation transmitter cost. The input fibres may be tapered and arranged in a hexagonal matrix. A similar, parallel, downstream communications arrangement is also provided.

Title: Method and system for detecting vehicle roll-over
Inventor: GIOUTSOS TONY
IPC: B60K28/14
Filed: 1995-08-11
Abstract: A method and a system for detecting a vehicle roll-over utilizes a z-axis accelerometer (12) and a processor (20) for analyzing the accelerometer output (18) to provide early detection/prediction of a vehicle rollover. The output signal (18) is substantially a positive constant value equal to the force of gravity when the vehicle (16) is in a normal upright condition, and as the vehicle (16) experiences a roll-over, the output signal transistors to a substantially negative constant value when the vehicle has rolled 180{ upside down. To provide early roll-over detection and/or prediction, the z-axis data is averaged (102) and compared to a first threshold value (104) set to a g-force value within a range of 0 to -1 g. Estimating a slope value (step 110), i.e. the change in z-axis data over time, can provide an additional discrimination measure to improve overall reliability, and to provide a qualitative measure of the roll-over.

Title: A digital polynomial predistortion arrangement
Inventor: KENINGTON PETER
IPC: H04B1/04
Filed: 1999-04-01
Abstract: The digital transmission sub-system comprises a DSP 100 which takes as its inputs the in-phase and quadrature channels of a baseband software radio stage. The in-phase and quadrature inputs are separately digitally predistorted 110,120 and digitally up-converted 128 to the intermediate frequency (IF) band. The IF band signal is then converted 130 to an analogue signal which is up-converted to the radio frequency band at 134 prior to amplification at 140 to produce an RF output signal for radiation from an antenna. The predistorters 110 and 120 predistort the incoming signals 10 counter distortion arising from the up-conversion and amplification processes within the transmission sub-system in order 10 linearise the RF output. The predistorters 110,120 may be adapted using a feedback signal supplied to the DSP 100 from a splitter 142 at the output of the sub-system. The feedback mechanism may involve analogue correlation processes to permit the use of slower analogue to digital converters for providing the feedback to the DSP 100 (figures 4 and 5). A pilot signal may be used.

Inventor: STRINGER ANDREW MARK
IPC: F02B47/02
Filed: 1999-08-23
Abstract: The piston is mounted rigidly on the connecting rod which passes, at each end of the cylinder, through bearing, sealing and guide parts 2. A combustion chamber is provided on each side of the piston; the arrangement could thus be described as a "reverse boxer" configuration. At least one end of the connecting rod may be connected via intermediate mechanism to a rotating output shaft. Apertures 5 in the body 4 are opened and sealed by suitable valve gear, eg side-valve gear, which may have variable valve timing. The bearing, sealing and guide parts 2 may be separated from the combustion chamber body 4 by thermal insulation pieces 3 so that the combustion chambers may operate at higher temperatures than normal. Water may be introduced into the combustion chambers, eg in the form of a spray to contribute to the pressure in the combustion chambers; this configuration could be regarded as a hybrid of an i.c. engine and a steam engine. The water spray may help regulate the operating temperature, allowing the engine to be enclosed in a thermally insulating jacket to minimise heat loss to the environment. Sealing means may be provided between the piston and cylinder walls, eg in the form of piston rings made from carbon, eg as graphite, or from boron nitride.
