Title: Method and device for raising loads using expandable cellular body
Inventor: STRONG PHILIP WALTER
IPC: A61G7/10
Filed: 1999-05-20
Abstract: A device for raising a load such as a hospital patient, and a method of using the device is described. The device comprises an expandable cellular body 10, located within an air tight container (11,12, 13, 14) such as a PVC bag, and valves (17, 18, 19, 20). In use the device, which is initially in a collapsed condition, is positioned under a load to be lifted. With the valves closed the air tight container prevents air from entering the cellular body, allowing the cellular body to remain in the collapsed condition. The load is lifted by opening a valve or valves so that ambient air can enter the cellular body, allowing it to expand. After use the cellular body may be returned to its collapsed condition by removing air through a valve or valves by means of a probe and vortex, a vacuum pump, or by applying a compressive force to the device. Preferably the cellular body is formed from an open-cell elastomeric material such as polyurethane foam with a density of 18 to 45 kilograms per cubic metre. The cellular body may comprise several individual pieces of material. It may be single use 10 punctured to expand or multi-use. Instead of a valve, patches may be used. The material can be polyurethane open celled foam.

Title: Fuel cleaning for gas fired engines
Inventor: HAYWARD JOHN
IPC: B01D53/02
Filed: 2002-12-19
Abstract: A method of cleaning the fuel gas feed to a internal combustion engine comprises passing the fuel gas through a filter containing activated earth. Preferably the activated earth is acid treated bentonite, a type of clay. The filter may consist of a hollow container having an inlet and outlet, wherein the container is packed with activated earth. The fuel gas may be biogas derived from the decomposition of waste materials. The container may be in the form of a refillable cartridge so that the activated earth can be regenerated as required. Gas fired internal combustion engines which are run on contaminated fuel suffer from the buildup of internal deposits and corrosion. This is a particular problem with engines fuelled by biogas, e.g. from waste decomposition. By filtering the fuel via an activated earth filter, substantial improvements can be obtained.

Title: Amplifier offset reduction in an LCD or EL display grey-level driver circuit
Inventor: NAKAHIRA YOSHIHIKO
IPC: G09G3/32
Filed: 2003-02-06
Abstract: The voltage offset in a thin-film transistor operational amplifier 10 may be considerable and may vary in dependence on the input voltage. To improve accuracy and save power in the offset cancelling circuit 11, separate capacitors 6-1 and 6-2 are used to store the amplifier offsets when the input signal is in a relatively positive or negative range respectively. The amplifier 10 may be of the commutating type (figures 9 and 13) where the inputs are periodically transposed to reduce the effective offset. Each capacitor may be associated with a separate amplifier input stage (figures 40-45) to improve accuracy by reduction of charge injection.

Patent GB-2399986-A (GB)
Title: Transmission parameter information
Inventor: VAERE JANI
IPC: H04N5/44
Filed: 2003-03-25
Abstract: A terrestrial digital video broadcast (DVB-T) network comprises a content provider 2 and first to third transmitters 3 to 5. Each transmitter may transmit more than one signal, different signals having different frequencies, multiplexes and the like and relating to different network types. An integrated receiver/decoder (IRD) 6 is mobile in the area around transmitters 3 to 5. As well as transmitting service information as part of a network information table on a data layer, the transmitters 3 to 5 provide in their output signals transmitter parameter information as TPS data on a physical layer. This TPS information includes one bit identifying the type of the network to which the signal relates and information identifying whether or not the signal contains time-sliced data streams. This information is used by the IRD 6 both in signal scan, or initialising the IRD with parameters needed for OSI layers 1 to 2 service discovery, and for deselecting signals as handover candidates. Since the transmission parameter information is transmitted more frequently and in a lower OSI layer than the network information table, the IRD 6 can more efficiently make decisions as to whether or not a signal is suitable for handover, or is otherwise a signal of interest. The network identifying data is positioned in bits S48-S53 of the TPS signal and can be used to distinguish between DVB-T and Internet Protocol Data Cart (IPDC) networks.

Title: Remote terminal location algorithm
Inventor: FOX BRIAN L
IPC: G01S5/02
Filed: 2001-10-05
Abstract: Various approaches for forming more accurate location estimates based on time-of-arrival measurements are disclosed. In some approaches, accuracy predictions are made before a location estimate is computed, and the location estimate is only computed when a high accuracy is predicted. In other approaches, a plurality of preliminary location estimates are computed, and the accuracy of each preliminary estimate is determined. A final location estimate is then based on the preliminary location estimates with the best determined accuracy. In some embodiments, the accuracy predictions and determinations are based on geometric dilution of precision (GDOP) or a known topography of a region. In another approach, a subset of time-of-arrival measurements is fed into a closed-form algorithm is to produce a preliminary location estimate. This preliminary location estimate is then used to initialize an open-form location algorithm. Optionally, more than one of these approaches may be combined.

Title: Cellular network identification and acquisition
Inventor: ORMSON RICHARD
IPC: H04W88/06
Filed: 2003-12-23
Abstract: A mobile radio communications device seeking connection to a network of a first radio access technology (RAT), such as WCDMA, scans a plurality of frequency bands to determine a signal characteristic for each band, such as signal strength, and analyses the characteristic of a plurality of frequency bands to identify a block of bands having a uniform characteristic, implying that a WCDMA has been located. Then, an attempt is made to connect at a centre frequency of the identified block of frequency bands. Alternatively, where at least two RATs, such as GSM and WCDMA, operate with partially overlapping frequency bands, signal characteristics of the common frequency bands may be determined and an attempt to connect on a first of the frequency bands in accordance with a first of the RATs is made. If the attempt fails, an attempt is made to connect to the same frequency band in accordance with a second of the RATs before attempting to correct to a second of the frequency bands.

Alternatively a switch on the pen or markings on the page may control when data is transmitted. LED, noise or vibration feedback indicates when transmission has been achieved. The data transmitted may identify the pen, a user ID or user's role. A user may need to login to use the pen. An 'e-signature' may be downloaded to the document from a wearable item (e.g. a ring, fig 6) or a PDA. A digital record may contain data from several pages and/or from several users. Movement may be sensed by a camera 13, and the pen includes a battery 16, a nib pressure sensor 19, a real time clock 18 and a processor 14. Tag and reader circuitry (fig 3) and suitable tag frequencies are disclosed.
