20100208551CONFIGURING WIRELESS SEISMIC ACQUISITION NETWORKS - Described herein are implementations of various technologies for a method for configuring a wireless seismic acquisition network. A plurality of seismic receivers may be positioned over a survey area in a fixed pattern. A first message may be received from the receivers. The first message may indicate one or more base stations that are available for transferring seismic data from the receivers to a recording system. A second message may be received from the base stations. The second message may indicate a maximum number of receivers for which each of the base stations can transfer seismic data. One of the base stations may be assigned to each receiver without exceeding the maximum number.08-19-2010
20100318299SYNCHRONIZING A SEISMIC DATA ACQUISITION NETWORK - Described herein are implementations of various technologies for a method for configuring a seismic data acquisition network. A first message may be received from a first node of the seismic data acquisition network over a first direct communication link. The first message may comprise a first precision quality of a first reference clock to which the first node may be synchronized. A second message may be received from a second node of the seismic data acquisition network over a second direct communication link. The second message may comprise a second precision quality of a second reference clock to which the second node may be synchronized. One of the first precision quality and the second precision quality may be determined to have a higher precision quality. A real time clock may be synchronized to one of the first reference clock and second reference clock having the higher precision quality.12-16-2010

20100164186INNER SEAL FOR CV JOINT BOOT - An inner seal is provided for protecting a CV joint boot for a CV joint. The CV joint includes a bearing, a back sealing means and a front can. The bearing operatively connects a first shaft and a second shaft. The bearing has an inner race and an outer race and has a front and a back. The first shaft is connected to the inner race. The second shaft is connected to the outer race. The front can is connected to the outer race. The back sealing means seals against leakage of lubricant from the back of the bearing. The inner seal comprises an inner seal body having a front can sealing portion for sealing with the front can to inhibit the migration of lubricant from the bearing therebetween. The inner seal body has a shaft sealing portion for sealing with the first shaft to inhibit the migration of lubricant from the bearing therebetween. The inner seal body has a shield portion that extends between the front can sealing portion and the shaft sealing.07-01-2010

20100246715WIRELESS COMMUNICATION METHOD AND APPARATUS - In a wireless communications system, a method of processing data prior to transmission thereof to a plurality of stations. The method includes determining a channel matrix using a plurality of weighted channel responses, each of which is associated with one of the plurality of stations and weighted by a gain factor corresponding to the station, wherein the gain factor is inversely proportional to a noise power of the station. The data is then processed in accordance with a precoding scheme using the determined channel matrix.09-30-2010
20110243045LINEAR MULTIUSER PRECODING WITH MULTIPLE-RECEIVE ANTENNA RECEIVERS - According to one embodiment there is provided a method performed in a transmitter side of a multiuser minimum square error linear precoding MIMO system that comprises a transmitter with a plurality of transmit antennae and a plurality of receivers. Each receiver of the plurality of receivers comprises a plurality of receive antennae. The method is a method of scheduling receivers from among the plurality of receivers and comprises obtaining, for some or all of the receivers, receiver channel information that quantifies the properties of transmit channels between receiver antennae of the receiver and transmit antennae of the transmitter and establishing an order for determining the receiver combining vectors of the some or all of the receivers. The order is established by selecting as a next receiver in the order a so far unselected receiver from the some or all of the receivers that minimally increases the mean square data transmission error. The establishing of the order is based on the channel information of any receivers previously selected in the order and of unselected receivers.10-06-2011
20110249613REMOTELY WEIGHTED SDMA TRANSMISSION - The present disclosure concerns the harnessing of the effect of a relay to enhance the ability to avoid the effect of interference at mobile stations. This is achieved either by overlaying beamforming for an indirectly reached mobile station so that a relay passes on this beamforming to the mobile station concerned, and retaining orthogonality therewith, or by harnessing a base station and a relay station together so that their combined effect is to provide spatial multiplexing to two or more mobile stations.10-13-2011

20100068415DEPOSITION OF AMORPHOUS SILICON FILMS BY ELECTRON CYCLOTRON RESONANCE - A method is described for forming a film of amorphous silicon (a-Si:H) on a substrate by deposition from a plasma. The substrate is placed in an enclosure, a film precursor gas is introduced into the enclosure, and unreacted and dissociated gas is extracted from the enclosure so as to provide a low pressure in the enclosure. Microwave energy is introduced into the gas within the enclosure to produce a plasma therein by distributed electron cyclotron resonance (DECR) and cause material to be deposited from the plasma on the substrate. The substrate is held during deposition at a temperature in the range 200-600° C., preferably 225-350° C. and a bias voltage is applied to the substrate at a level to give rise to a sheath potential in the range −30 to −105V, preferably using a source of RF power in the range of 50-250 mW/cm2 of the area of the substrate holder.03-18-2010
