Title: MIMO receiver determines first symbol using maximum likelihood and then determines remaining symbol pair based on their orthogonal transmission
Inventor: SKRAPARLIS DIMITRIOS
IPC: H03M13/39
Filed: 2004-09-14
Abstract: A receiver which receives a multiple element signal from a MIMO transmission. The receiver identifies symbols, from a predetermined set of symbols. The receiver estimates the corresponding bits according to a pre-defined mapping of symbols to bits along with associated likelihood information. The decoding operates in two stages. A first stage searches exhaustively a set of possible symbols for the most likely (ML) candidate symbol, while a second stage takes account of an orthogonal transmission of information on two transmit antennas and decodes this information accordingly. The second stage is operable to detect remaining bits of data. The orthogonal transmission may be based on Alamouti space time block codes (STBC) or the like. The system simplifies the decoding process for the symbols. The first stage may be further simplified by only searching constellation points close to a solution derived by zero forcing.

Title: Processing and display of a real world model
Inventor: TAYLOR RICHARD
IPC: G06F17/10
Filed: 2005-08-27
Abstract: An analysis method takes an input model of a real world process with an output parameter, with multiple input parameters. The complexity of regions of the model is determined to locate regions of low complexity, that is to say low sensitivity of the output parameters to the input parameters. The input parameters may be ordered and the results displayed on view of a two dimensional surface starting with the first parameter and ending with the last. The display may represent the value of the output parameter by the length of a bar on the relevant part of the two dimensional surface. A combination of automatic parameter ordering and/or user input may be used to locate suitable regions. The real world process may be: a supply chain, location of tills operated over time in a store, the number of parking spaces provided outside a shopping mall, or the route to take to reach a destination through a public network.

Title: Push-push latch which is locked if applied force is greater than a predetermined value
Inventor: HABA CHARLES
IPC: E05B65/12
Filed: 2005-10-19
Abstract: The push-push latch 20 is attached to a storage compartment (22, fig.1) and allows the door (24) of the compartment (22) to move between an open position and a closed position. The latch 20 will remain closed and in a locked position when the door (24) is subjected to a force greater than a predetermined force. The latch 20 includes a track member 30 and a guide member 32. . The track member 30 is molded of a polymer and generally defines a heart shaped track 34 having an integrated retaining section 28 and a channel 58 connecting the heart shaped track 34 and the retaining section 28. The guide member 32 moves within the heart shaped track 34 to facilitate opening and closing of the compartment door (24). In the event that the compartment door (24) is subjected to a force greater than a predetermined value while in the closed position, the guide member 32 will be forced through the channel 58 and locked into the retaining section 28, thereby retaining the door (24) in its closed position. Therefore, the door is prevented from opening in the event of a collision or accident.

Title: Amplification of filtered audio input signal
Inventor: JENKINS CHRISTOPHER SEFTON
IPC: H04H60/04
Filed: 2005-12-22
Abstract: An Audio input signal is processed to produce a processed audio output signal. An input signal is dynamically filtered to produce a first stage signal consisting of a selected frequency band of the input signal. Gain applied to the first stage signal is dynamically controlled in response to a control signal to produce a second stage signal. The control signal is derived from the first stage signal and the second stage signal is processed in combination with the input signal to produce an output signal. This arrangement allows a user to amplify an unwanted signal frequency (for example, background noise) to identify its frequency band, and then to invert this and re-combine it with the original input signal to remove the unwanted frequency. Therefore, the user can process the sound by ear, and does not need sophisticated graphics.

The device 10 may comprise two pieces of plastic or metal secured to the rear wall of the packet and its lid respectively to serve as a tamper-evident feature by 'clicking' on initial opening, which causes the device to rupture. Parts making up the packet are tightly glued so that the cigarettes are kept in air tight conditions, isolated from the matches and striker, until opening.
Patent GB-2438454-A (GB)
Title: Multicast transmissions in IP compatible wireless communication systems
Inventor: JAKOBSEN JENS
IPC: H04B7/00
Filed: 2006-05-26
Abstract: A zone controller receives a call set up request from a mobile station MS and before the zone controller allocates channel resources and sends a call grant message (203), the zone controller sends a prompt message to network routers to enable the router network to form a multicast tree (203, 213, 215 then 217). This enables the multicast tree to be substantially formed before the transmission of traffic information begins (211). This is especially useful if one or more of the target MSs or base stations BS has a satellite link to the communication network. In the prior art method, the BSs receive and relay the call grant message from the zone controller, then send join messages to routers who later form the multicast tree (201, 203, 205, 207, 219, 221 then 223).

Title: Downhole Lock
Inventor: MARTIN DAVID GLEN
IPC: E21B23/04
Filed: 2006-06-23
Abstract: A downhole lock contains a housing 4 and a burst or rupture disc 5. A moveable mandrel 15 is held in place by a shear screw 17, locating in a groove on an inner sleeve 8. The mandrel 15, fishing neck 1 and housing 4 form an upper hydrostatic chamber 18 of a piston assembly. A lower hydrostatic chamber 19 is formed by the housing 4, rupture disc 5 and mandrel 15. Spring 9 biases the inner mandrel 12 upwards, with shear screw 17 preventing the mandrel 15 moving and inadvertently activating the keys 11 of the locking mechanism. A predetermined well pressure is defined to activate the lock via the rupture disc. A thread 20 is used to connect the lock to accessories and hence to the central conduit, by which means the lock assembly is conveyed to the appropriate point in the well tubing string. The lock does not require the use of a dedicated running tool.

Title: Water cooled constant temperature liquid circulating device
Inventor: ICHINOSE TAKEO
IPC: F25D17/02
Filed: 2006-09-29
Abstract: A heat exchange portion 11c of a radiator tube 11 in which flow regulated water flows passes through a tank 10 containing constant temperature circulating liquid. A pump 14 in a conduit 13 allows constant temperature liquid to circulate through an external device 2. An electric proportional valve 24 controls the flow amount of water delivered to the heat exchange portion as a function of its opening degree and an electromagnetic valve 26 is also provided for controlling delivery of the water to the heat exchange portion in an amount regulated by controlling the opening-closing frequency or duration thereof. As electric proportional valves are unreliable below a given minimum flow, the proportional valve controls flow down to a lower flow limit, whereafter the flow is controlled by the electromagnetic valve. The valves may be series connected with each other and the heat exchange portion or the proportional valve may bypass the heat exchange portion.
