Title: Transmitter which selects between OFDM and MC-CDMA
Inventor: LEE KYESAN
IPC: H04B1/707
Filed: 2003-10-29
Abstract: A transmitter device comprises an OFDM transmission unit, a multi-carrier CDMA transmission unit, and a control unit for selecting either the OFDM transmission unit or the multicarrier-CDMA transmission unit in response to propagation conditions. The propagation conditions are a distance from the receiver device and the ratio of signal power to the sum of interference and noise power (SINR). The propagation conditions may also include delay spread and maximum Doppler frequency. TDMA is used. Within a single frame some time slots may use conventional OFDM whilst others use MC-CDMA (see Fig. 3). The modulation conditions, coding rate and spreading rate may each be adapted in response to the propagation conditions.

Title: Automatically synchronising a timebase on a mobile communication device
Inventor: ORMSON RICHARD
IPC: H04B7/26
Filed: 2003-11-17
Abstract: A typical mobile device will receive signals from non-serving base stations. These signals are transmitted in cycles and the mobile device will "listen out" for parts of the cycle at specified times. However, as the device moves further or closer to the base station the time of arrival of the signal will change, and the device will lose synchronisation with the base station. Current systems account for this by increasing the size of the arrival window. This is inefficient and also there is the possibility that in extreme cases an arrival could be missed completely. The present invention overcomes this problem by finding the location of the base station (e.g. GPS) and comparing it with the present location of the mobile device (by GPS or any other known technique). The time of arrival of the required information can then be calculated.

Title: Enabling communication between two network nodes
Inventor: VEITS OLIVER
IPC: H04L12/66
Filed: 2004-10-23
Abstract: The network address translation (NAT) carried out by routers in communication networks hides the true IP addresses of nodes in a local network. This poses several challenges on all protocols like e.g. H.323 and SIP, which place IP-addresses in the signalling data. RFC 3489 - "STUN - Simple Traversal of User Datagram Protocol" describes a method on how an endpoint of a data flow can learn about its globally valid internet address. However, there exist situations, where this global internet address is not visible to communication partners, e.g. because the addresses within a corporate network overlap with official internet addresses. The current invention seeks to generalize the concept described in RFC 3489 in order to also solve those situations, where an address translation of both, the source and the destination address takes place in a single network node. In addition a method of translating IP addresses found in signalling data by intermediate nodes (e.g. Gatekeepers) is defined. With this method, the H.323- or SIP-stack of the endpoints can be kept unchanged, while all translation work is done in the intermediate nodes.

Title: Freeze-thaw valve limiting cryogenic usage
Inventor: GERHARDT GEOFF
IPC: F16K31/00
Filed: 2003-09-15
Abstract: Methods and devices for the management of cryogenic agents within analytical systems using freeze thaw valving having an expansion chamber (101) that limits the flow of the cryogenic agent. The expansion chamber (101) is fitted with an expansion nozzle (106) through which a cryogen flows and a porous frit (105) that allows the cryogen to he exhausted. The porous frit (105) initially allows a rapid flow of cryogen into the expansion chamber (101). This rapid flow lowers the temperature of the expansion chamber (101) causing fluid contents within a freeze thaw segment (103) to freeze. As the cryogen expands into the expansion chamber (101) and turns into a solid, the porous frit (105) is occluded causing the rapid flow to be restricted. The restriction of the cryogen flow by the occlusion of the porous frit (105) allows the freeze thaw valve to use significantly less cryogen. Sublimation of the cryogen trapped within the porous frit (105) provides sufficient cooling to maintain the valve in its closed position.

Title: Multi-leaf collimator with rack and pinion actuator
Inventor: PERKINS CLIFFORD WILLIAM
IPC: G21K1/04
Filed: 2005-03-04
Abstract: A multi-leaf collimator comprises an elongate leaf moveable in a longitudinal direction, and having an associated toothed rack driven by a pinion, wherein the rack is carried on an elongate actuator section, having a transversely extending link section, the leaf being connected to the link section and thereby being spaced from the actuator section. The pinion can thus be mounted on a shaft which is disposed transversely to the leaves of the array, and which passes between those leaves and their respective actuators. Some leaves can be driven via pinions mounted on shafts passing over the array, and other leaves can be driven via pinions mounted on shafts passing within the gaps between leaves and actuators. This means that twice the number of drive shafts can be fitted into the same length of array, thus either shortening the array or permitting more leaves and hence greater resolution. The drive mechanism can also be made as a separate unit. A separate drive unit is advantageous in manufacturing as it allows the drive unit to be produced, built and tested as a separate assembly in a specialist environment. Service replacement of the entire gearbox in the event of a fault will also be swifter, with minimal re-setting. Further, the gearbox will be an enclosed unit, with integral lubrication and shielded from environmental dust and debris. The invention also offers a major advantage in the leaf length is no longer dictated by the length of the rack. The leaf can be made smaller, saving material and reducing its weight. That reduction in weight will make movement of the leaf easier, improving both accuracy and reliability.

Title: Method for predicting quantitative values of a rock or fluid property in a reservoir using seismic data
Inventor: HAMMAN JEFFRY G
IPC: G01V1/30
Filed: 2005-12-20
Abstract: A method is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume. A first predicted value of the designated rock or fluid property is also assigned to a volume of a multi-dimensional, multi-scale model. A first predicted value of seismic response for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. A synthetic trace is generated and iteratively compared to the corresponding trace obtained from one or more sets of actual seismic data to determine a difference while consistency is maintained between the types, scales and dimensions of values and data. The first predicted value of the designated rock or fluid property is adjusted in response to the difference to create a second predicted value of the designated rock or fluid property, wherein the second predicted value generally reduces the difference.
