Title: Energy efficient medium access control protocol and system for sensor networks
Inventor: YOON CHANG-JUNE
IPC: H04L12/28
Filed: 2005-11-17
Abstract: An energy efficient MAC protocol for a sensor network that extends the battery life of remotely located wireless nodes 200 by employing MAC operations involving transmission of a wake-up signal with more processing gain, dynamic adjustment of a transmission rate of synchronization messages for fast time synchronization and an energy efficient neighboring node discovery technique. The wake up signal may have an increased range, chip rate, bandwidth or lower bit rate. A receiving node enters a wake-up state and re-broadcasts the wake-up signal prior to switching to a higher power consumption receiver to receive a synchronisation message. The transmission rate for sychronisation messages and node discovery messages is selected as a function of one of more factors including a number of node hops between the synchronised node and a certain node, remaining available power level and number of messages previously transmitted.

Title: Self-aligning well tool guide for insertion into a pre-installed lateral tubular
Inventor: CASSIDY JOSEPH H
IPC: E21B23/00
Filed: 2007-07-12
Abstract: A downhole tool 200 comprises a body 202 having a nose portion 203 and an orientation mule shoe 212 coupled to the nose portion. The mule shoe is actuable to lift the nose portion away from the floor of the lateral borehole and into alignment with a tubular 108. Preferably, a leading face 214 of the mule shoe includes a flat portion 216 that abuts against an opposing edge 108a of the tubular. The resultant force overcomes a compression spring 228 so that a pin 220 provided on the mule travels along a helical groove 226 so as to rotate the mule shoe. Once rotated, a tapered portion 218 contacts the edge of the tubular and serves to lift the tool into alignment with the tubular. The arrangement is particularly useful where an eccentricity exists between the tubular and the lateral borehole, possibly as a result of formation washout.

There may be more than one locking mechanism and it/they may comprise at least one shot bolt and/or locking pin.
Patent GB-2455071-A (GB)
Title: Memory efficient data symbol interleaver which adaptively applies odd only, or odd and even interleaving processes, depending on OFDM mode
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H04J11/00
Filed: 2007-11-19
Abstract: In this abstract "cell" is used in place of "data symbol" to avoid confusion with "OFDM symbol". A cell interleaver for OFDM is capable of operating a first (e.g. "odd") interleaving process and a second (e.g. "even") interleaving process. When the interleaver is used in a first OFDM mode (e.g. the 32K mode) with a first number of sub-carriers the first interleaving process is applied to input cells destined for odd numbered OFDM symbols and the second interleaving process is applied to input cells destined for even numbered OFDM symbols, but when the interleaver is used in a second OFDM mode (e.g. the 16K mode), with a number of sub-carriers which is less than or equal to half the number of sub-carries of the first OFDM mode, the first interleaving process is applied to cells for both odd and even numbered OFDM symbols. The first interleaving process involves writing cells into interleaver memory in sequential order and reading cells from memory in an order defined by a permuted code, whilst the second interleaving process involves writing cells into the same interleaver memory in the order defined by the same permuted code and reading cells out from the memory in sequential order. Thus, a single memory location can be used to simultaneously process an odd symbol and an even symbol. This invention combines this memory efficiency for the 32K mode with improved interleaver performance for lower modes. The invention finds particular application in DVB-T.

Title: Vehicle drive with regenerative braking and flywheel
Inventor: BAKER MARK
IPC: B60K6/10
Filed: 2008-07-18
Abstract: A kinetic energy (KE) drive is provided for vehicle regenerative braking using a planetary gearing system and flywheel. It stores energy otherwise lost when braking. A high efficiency continuously variable transmission system converts vehicular KE or gravitational potential energy into flywheel KE and back and stores prime motive energy as flywheel KE which can then be to give the vehicle KE or gravitational potential energy which may be deployed at a significantly higher power output than the prime motive energy for short periods. The device comprises a planetary gear system transferring KE three ways between the power source, typically an internal combustion engine, a diesel engine or gas turbine, one or more drive wheels, and a flywheel which may be compact and recessed within the drive wheel or separately mounted in the vehicle. When the vehicle is braked to restrict speed increase on a downward gradient or to slow the vehicle down, the differential transmits energy to the flywheel rather than losing the energy entirely to frictional losses. For acceleration, the flywheel KE is transmitted to the drive wheel directly or through a transmission shaft which may lead to a differential system. Energy from the power plant can be sent to the drive wheels or to the flywheel selectively or both at a chosen ratio. The power plant can be of a lower peak output as peak power can be supplemented by the flywheel. This invention can add inexpensive, high efficiency regenerative braking to existing vehicle models.

Title: A photoconductive switch
Inventor: JOHN DAVIES
IPC: H01L31/09
Filed: 2008-07-29
Abstract: A photoconductive switch comprises a GaAs substrate and a generally circular pattern of gold/titanium contacts. The on-resistance of the switch does not depend on the pOlarisation of the incident light and so the switch is suitable for use where vibration of a single-mode fibre supplying the incident light pulse causes changes in polarisation. The switch may be used in a high-speed sample-and hold circuit or in an optical fibre communications receiver.

Title: Method of routing analogue or digital audio or visual (AV) data using main and redundant crosspoint modules
Inventor: GREENHALGH STEPHEN PAUL
IPC: H04H20/26
Filed: 2009-04-09
Abstract: In a method of routing or distribution of analogue or digital audio or video data, input modules I1-I24 receive source data at plural inputs and send corresponding input signals to crosspoint modules X1-X4; output modules O1-O24 supply destination data to plural data destinations from plural data outputs, receiving corresponding output signals from crosspoint modules; and main crosspoint modules, and a redundant crosspoint module XR, control routing of outputs from input modules to inputs of the output modules. Input modules are divided into groups and each main crosspoint module receives one group from every input module, and input modules send a duplicate of one selected group corresponding input signals to a redundant crosspoint module XR. Alternatively, as also independently claimed, destination data outputs are divided into groups, each output module receiving one group of corresponding output signals from every main crosspoint module, and output modules receive a group of corresponding output signals from a redundant crosspoint module and can use that group in place of any group of corresponding output signals from a main crosspoint to derive destination data at a destination output.

Title: Power Optimised Dynamic Port Association
Inventor: POR CHOON GUN
IPC: G06F1/32
Filed: 2009-07-03
Abstract: In a computer system having at least two host controllers 100, 102 for communicating with attached devices 104...126 using a specific protocol, such as USB or SATA, port association logic associates active communications ports with host controllers. Each host controller has the capability to control a maximum number of ports. If the total number of currently active ports is less than the maximum number of ports controllable by a first host controller, then a newly active port is associated with the first host controller and a second host controller is prevented from powering to an operating state. However, if the total number of currently active ports is greater than or equal to the maximum number of ports controllable by the first host controller then a newly active port 112 is associated with a second host controller. If there are no active ports then the first host controller is powered down. The invention reduces power consumption by dynamically associating and re-associating ports to host controllers such that the number of powered host controllers is kept to a minimum. The invention can be expanded to accommodate any number of host controllers.
