20080317149WIRELESS COMMUNICATION DEVICE AND METHOD FOR REDUCING CARRIER FREQUENCY OFFSETS OVER A SIMULTANEOUS MULTI-USER UPLINK IN A MULTICARRIER COMMUNICATION NETWORK - Each of a plurality of multicarrier wireless communication devices generate a carrier frequency offset (CFO) estimate from a downlink polling frame (12-25-2008
20090041144MULTI-USER MIMO RECEIVER AND METHOD FOR DECODING SIMULTANEOUS UPLINK TRANSMISSIONS FROM MOBILE STATIONS - Multicarrier receivers and methods for carrier frequency offset correction and channel estimation for receipt of simultaneous transmissions over a multi-user uplink are generally described herein. Other embodiments may be described and claimed.02-12-2009
20100013758HUMAN INTERFACE DEVICE (HID) - A user may wear the radio frequency human interface device on a body portion and move the body portion over any even and un-even surface that is not touch sensitive to provide inputs. The radio frequency human interface device may sense, encode, and provide the radio frequency signals to a computing system. The computing system may be provisioned with a radio frequency reader that may receive the radio frequency signal and decode the radio frequency signal before responding to the input. Also, a plurality of users may use radio frequency human interface devices to provide inputs to the computing system concurrently.01-21-2010

20090245286METHOD AND APPARATUS FOR PHYSICAL LAYER ROUTING IN A WIRELESS DEVICE - A method includes, in a physical layer of a communication stack of a wireless communication device, receiving a first radio frequency (RF) signal, converting the first RF signal to a first digital data signal, and passing the first digital data signal to a higher communication stack layer. The method also includes, in the physical layer, receiving a second digital data signal from the higher communication stack layer, converting the second digital data signal to a second RF signal, and transmitting the second RF signal. The method further includes, in the physical layer, forwarding a signal, wherein forwarding comprises receiving a third RF signal, converting the third RF signal to a fourth RF signal, and transmitting the fourth RF signal.10-01-2009
20090257420Process Control System With Enhanced Communication Throughput Using Frequency Agility - A process control system having wireless nodes (field devices, routers, wireless gateways, etc.) communicating with enhanced throughput using frequency hopping. The frequency channel using which each node transmits is determined by frequency agility/frequency hopping technique. Multiple nodes then transmit the packets in their respective channels, but in overlapping duration. In one embodiment such a technique is employed in combination with TDMA, with the boundaries of time slots being ‘global’ (same for all the nodes in the network) and thus the overlapping duration equals the duration of the time slot. In an alternative embodiment employed in combination of SDMA, each node transmits in a (substantially) non-overlapping corresponding beam area, but without reference to global boundaries. In yet another alternative embodiment, a combination of SDMA, TDMA and overlapping duration is used.10-15-2009
20100315298METHOD FOR ACHIEVING INTRINSIC SAFETY COMPLIANCE IN WIRELESS DEVICES USING ISOLATED OVERLAPPING GROUNDS AND RELATED APPARATUS - A system includes a wireless radio board, an antenna, and a ground pattern having a radio board ground and an antenna ground. At least a portion of the radio board ground and at least a portion of the antenna ground overlap. The radio board ground could include a first portion in a first layer of the ground pattern and a second portion in a second layer of the ground pattern, and the antenna ground could include a first portion in the first layer of the ground pattern. The antenna ground could further include a second portion in the second layer of the ground pattern. The radio board and antenna grounds could be separated by a minimum distance, such as 0.5 mm or 3.0 mm.12-16-2010

20100239132FINGERPRINT TEMPLATE GENERATION, VERIFICATION AND IDENTIFICATION SYSTEM - A system to generate a template of a fingerprint input image is described. The system provides for smoothing the input image, forming a binary image from it, and further processing the binary image to extract the minutia of the fingerprint. The minutiae are stored in the template, in the form of locations of each minutia in relation to all other minutiae. The system includes optional identification and verification steps, which compare the template generated according to the system with templates stored in a fingerprint database.09-23-2010

20100165958SYSTEM AND METHOD FOR FACILITATING FAIR ASSOCIATION OF CLIENT DEVICES WITH ACCESS POINTS IN A WIRELESS COMMUNICATION SYSTEM - A method for facilitating association of a client device with an access point in a wireless communication system is disclosed. The method comprises the access point receiving at least one client parameter and required throughput from the client device. The access point computes an achievable transmission rate for the client device based on the client parameter. The access point then estimates throughput for the client device based on the achievable transmission rate. Thereafter, the access point computes a utility value considering an association with the client device. The utility value is based oil the estimated throughput and the required throughput of the client device. The access point then determines a possibility of an association of the client device based on the utility value.07-01-2010
