Title: Trellis decoding using estimates of transmitted codewords and channel responses in a MIMO-OFDM system
Inventor: PIECHOCKI ROBERT JAN
IPC: H04L1/06
Filed: 2002-08-15
Abstract: The application is concerned with decoding a signal sent from a plurality of transmit antennae and received by at least one antenna, the signal comprising codewords having a finite plurality of states and associated transitions and having been modified by respective channel responses for each transmit path, wherein at the decoder a set of estimated codewords and associated channel responses is derived and trellis decoding techniques are employed using the received signal and the derived estimates. The coding is performed by a coding machine operating as a state machine having a series of allowable transitions between states. - The method comprises determining an initial estimate for said set of channel responses and selecting an assumed initial state of said coding machine; extrapolating from said initial estimate and state using said received signal to determine a set of estimated transmitted codewords and associated sets of channel responses, each estimated codeword having an associated estimated set of channel responses; and determining an estimated input data symbol sequence from said set of estimated transmitted codewords to decode said received signal. The extrapolation comprises a plurality of iterations, each iteration comprising establishing a set of allowed transitions from each possible state of said coding machine at a said iteration to each allowed new state of said coding machine for a next iteration; selecting, for each allowed new state of said coding machine with a plurality of allowed transitions to the new state, one of said plurality of transitions by estimating a set of channel responses for each said allowed transition and comparing, for each said allowed transition, said received signal to a codeword associated with the transition modified by said estimated set of channel responses associated with the transition; and then updating the estimated set of channel responses associated with the selected transition using said received signal.

Title: Communications in a processor array
Inventor: PANESAR GAJINDER
IPC: G06F/
Filed: 2003-02-21
Abstract: Data is transmitted from a sending processor over a network to one or more receiving processor in a forward direction during an allocated slot, and acknowledge signals are sent in a reverse direction during the same allocated slot, to indicate whether the receiving processor is able to receive data. If one or more of the receiving processors indicates that it is unable to receive the data, the data is retransmitted during the next allocated slot. This means that the sending processor is able to determine within the slot period whether a retransmission is necessary, but that the slot period only needs to be long enough for one-way communication.

Title: Method and apparatus to provide miniature formation fluid sample
Inventor: CERNOSEK JAMES T
IPC: E21B49/08
Filed: 2002-03-12
Abstract: An apparatus (20) and method is given for evaluating a well fluid sub-sample at the well surface as the sample is transported to the well surface from a downhole wellbore location (11).

Multiple collection tanks (30) can be lowered into the wellbore during the same run to sample different zones with minimal rig time. A pair of valves (75 and 76) in series along the supply/discharge conduit (78) respective to each tank (30) accommodates extraction of a filed sample to verify the sample integrity while still on location. The tanks (30) can be emptied at the well surface with an evacuation pressure so that the fluid sample pressure is maintained above a selected pressure at all times or transported to an analytical laboratory.

Title: Seismic velocity update for anisotropic depth migration
Inventor: ZHANG YAOHUI
IPC: G01V1/28
Filed: 2004-04-28
Abstract: A method of updating velocity whereby corresponding reflections are identified from P-P and P-S near-offset waves received from a seismic source and reflected by a subsurface layer to form P-P and P-S depth consistent image gathers. A joint velocity inversion in depth is performed on the P-P and P-S depth consistent image gathers to estimate a vertical depth zo, vertical P-wave velocity vpo, and vertical S-wave velocity vso of the subsurface layer. An isotropic depth migration of P-P depth consistent image gathers is determined based upon the depth zo, P-wave velocity vpo, and S-wave velocity vso to estimate a vertical isotropic depth zpp of the subsurface layer. Anisotropic parameters   w  and   s  are calculated based upon the depth zpp, P-wave velocity vp0, and S-wave velocity vso. The above steps are repeated, beginning with the joint velocity inversion, until the P-wave velocity vpo and S-wave velocity vso are substantially unchanged.

Title: Heater system and heater system control method for a refrigerator
Inventor: AN SI-YEON
IPC: F25D29/00
Filed: 2004-09-28
Abstract: A heater system and method of control of a heater for a refrigerator provided with a dispenser (140 fig 3) connected to a water tank (170 fig 3). The system has a heater (150 fig 3) mounted at a side of the tank, a first temperature sensor (12A fig 3) mounted on the tank which senses the tank temperature, and a second temperature sensor (12B fig 3) which senses the ambient temperature of the refrigerator. The system also has a controller (130 fig 2) which estimates the water temperature based on the tank surface temperature and the refrigerator ambient temperature, and then operates the heater as required according to a predetermined temperature regime. The temperature regime prevents the water in the tank from becoming frozen. The controller may turn the heater off if the water temperature is above a specified temperature, such as 7 { C, and turn the heater on if the water is below a specified temperature, such as 3 { C . Additionally, the heater on/off cycle times may be varied dependant upon the ambient refrigerator temperature. When the refrigerator ambient temperature is above a predetermined temperature, such as 25 { C, the heater on/off times may both be of 30 minutes duration. However if the refrigerator ambient temperature is below a predetermined temperature, such as 15 { C, the heater on/off times may be 50 minutes and 10 minutes, respectively.
