Title: Transmission of signalling information in an OFDM communication system
Inventor: ROUQUETTE-LEVEIL STEPHANIE
IPC: H04L27/26
Filed: 2005-05-03
Abstract: An Orthogonal Frequency Division Multiplexing, OFDM, transmitter comprises a signalling data generator (113) which generates a set of data symbols (e.g. in the SIG-N field) indicative of physical layer characteristics (e.g. modulation scheme, coding rate etc.) of data transmissions from the OFDM transmitter (100). A first symbol generator (115) and second symbol generator (117) generates a first and second OFDM signalling symbol (the second symbol being a repetition of the first symbol), by allocating the set of data symbols to subcarriers. The allocation of the physical layer data symbols to subcarriers is different for the first OFDM signalling symbol and the second OFDM signalling symbol. A data packet generator (105) and transmitter (101) generate a data packet and transmit this to an OFDM receiver (300). The OFDM receiver (300) determines the physical layer data symbols by combining the data symbols of corresponding subcarriers of the first and second OFDM signalling symbols and uses the resulting information to decode the user data of the data packet. An improved performance and range extension is achieved.

Title: Tyre pressure monitoring system
Inventor: ZOEPF STEPHEN
IPC: B60C23/00
Filed: 2005-07-12
Abstract: A tyre pressure monitoring system 12 suitable for a vehicle 10 has a refill pressure threshold. The system 12 is operable such that if the tyre pressure remains at a level below the refill pressure threshold for a specific period of time, based on the amount of deviation from the refill pressure threshold, a refill alert is generated. The system may also include a bleed pressure threshold and if the tyre pressure remains at a level above the bleed pressure threshold for a specified period of time, based on the amount of deviation from the bleed pressure threshold, a bleed alert is generated by the system 12. The time period may be inversely proportional or linearly related to the amount of deviation from the pressure thresholds. In addition, an alert may be generated when the tyre pressure falls below a low pressure threshold.

Title: Vehicle yaw control with tyre-road friction estimator
Inventor: HANCOCK MATTHEW J
IPC: B60W40/06
Filed: 2005-08-01
Abstract: A control module 12 comprises a friction estimator 18 that computes from information provided by on-board sensors an estimated value of the friction between a vehicle's tyres and the ground over which the vehicle is travelling. The friction estimator 18 has an output which is connected to an input of a target yaw rate generator 19 and from information supplied by a vehicle speed sensor (13, fig 1), steering angle sensor (17) and friction estimator 18, the target yaw rate generator computes a target (desired) yaw rate. A feedback controller 20 compares an actual vehicle yaw rate, measured by a yaw rate sensor (15), with the target yaw rate. The feedback controller 20, on comparing the two yaw rate values on its inputs detects if an oversteer condition exists. If this is the case an error signal is generated by the feedback controller 20 and this signal is applied to an electric motor (11) which controls a clutch (10) in an active limited slip differential (9) in order to control the yaw stability of the vehicle. In another embodiment the control module 12 includes a feedforward controller (26, fig 3) and a summer (25).

IPC: B65D19/14
Filed: 2006-03-15
Abstract: There is provided a process for recycling timber pallets in which the timber pallets are first of all separated into three categories, timber pallets ready for immediate re-use, timber pallets in need of repair and timber pallets suitable for disassembly. The timber pallets suitable for disassembly are sent to a recycling station where they are disassembled and parts suitable for use in the repair of other damaged timber pallets are sent to the repair station and parts that cannot be reused are sent to a hopper for subsequent recycling. The repair station has equipment to repair the timber pallets in need of repair by removing any components that are broken and using the parts taken from the recycling station to fix the existing timber pallets. The majority of components used to repair broken timber pallets are taken from those timber pallets unsuitable for repair thereby avoiding the expense of buying new components.

Title: Target device programmer
Inventor: FORD SIMON ANDREW
IPC: G06F9/445
Filed: 2007-06-08
Abstract: A programmer for programming a target device comprises a mass storage interface 14 and processing logic 16 coupled to the mass storage interface. In operation the logic generates signals so as to appear as a mass storage device to a host 2 in order that a file containing an image can be transferred from the host to the programmer as if the programmer were a mass storage device. In response to receiving the image the target device programmer generates programming signals to extract the image from the transferred file and applies the image to the target device. The target device may be a FPGA and the file a configuration file. The target device may be a separate device to the programmer and may be coupled to the programmer by a JTAG interface.(Fig 2) The host connection may be via a USB interface 8 and 12. The connection to the target device may also be via a UART interface. In one embodiment the host may be connected to a web based compiler 6 for compiling source code to generate the image file for the device.

Title: Pop up structure
Inventor: THOMPSON MARK ANTHONY
IPC: A47D13/02
Filed: 2007-08-04
Abstract: A collapsible structure, for example a travel cot for a baby, comprises a first frame 10 with at least one flexible rod formed into a first continuous substantially planar ground loop and a second frame 20 with at least one flexible rod formed into a second continuous saddle shaped loop above the ground loop. A fabric covering 50 is configured to fit over the first and second frames 10, 20 with at least a major part of the flexible rods fitting through fabric sleeves provided on the covering. First and second bent or arcuate flexible rods 30, 40 are positioned between the first and second frames 10, 20 without extending across them. These additional rods 30, 40 serve to hold open the ends of the fabric covering 50 in the erect condition of the pop-up structure, ensuring that the fabric is held away from the face or body of a child inside the cot. In an alternative structure, the first and second frames 10, 20 may be replaced by a single flexible rod formed into a first continuous substantially planar ground loop and into a second continuous saddle shaped loop thereabove. The frames may pass through a fabric sleeve 22 which holds them in position, the sleeve may accommodate both frames together where they run alongside each other. The structure may collapse down and be stored or transported in a bag (Figures 8/9).

Title: Electrical connector and socket assemblies suitable for use in a submersible pump
Inventor: KENNEDY STEVEN CHARLES
IPC: H01R13/523
Filed: 2005-12-06
Abstract: An electrical connector assembly is provided for a cable having a plurality of insulated conductors 20. The connector assembly 1 comprises a body 84 having a respective recess for receiving a terminating pin 87 of each of the conductors 20. Furthermore a seal 83 is associated with each of the conductors 20 and acts between an outer surface of each terminating pin 87 and an inner surface of the corresponding recess. Additionally an outer seal 88 on an outer surface of the body 84 seals the body within a motor head when the connector assembly is engaged with a corresponding socket assembly. Such an arrangement has the advantage that the primary sealing means with respect to the conductor no longer bears against the conductor insulation that is liable to swell when subjected to the high temperature downhole environment. Instead the sealing means bears against the outer surface of the conductive terminating pin which is much more stable at high temperatures. An insulating barrier preferably covers the pin/conductor connection to provide increased electrical integrity. Most preferably the barrier is sealed with elastomeric calk, with a crimped lead sheath or by crimping of the barrier itself to a lead sheath so as to render the connection gas tight. The outer seal may be an O-ring 88 or an elastomeric sealing member 88'. Spigots 86 may be sealed to both the recess (by seal 85) and the conductors 20. The corresponding socket may have an insulating sleeve (41, Fig 9).
