Communication apparatus and communication method
Power saving cannot be implemented in the adhoc mode by only the IEEE 802.11 standard. This is because communication partners mutually utilize the power save mode in the adhoc mode, and their states must always be managed. In the adhoc mode, the number of communication partners is not always one, and all stations which join a network are candidates, increasing the load of implementation. To solve this problem, a communication apparatus notifies a change to power save mode by an ATIM packet, RTS packet, or null packet. When the ATIM packet or RTS packet is transmitted, the communication apparatus can notify the partner of a change in mode regardless of whether the partner is in the power save mode. When the null packet is transmitted, the communication apparatus can rapidly notify the partner without waiting for any beacon. |

Increased absorption-measurement accuracy through windowing of photon-transit times to account for scattering in continuous webs and powders
Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements. |

Power consumption reduction technique for integrated wireless radio receiver front-ends
The method and apparatus disclosed herein reduces the power consumption of a wireless transceiver by reducing the power consumption associated with the corresponding wireless receiver.

Network based location of mobile transmitters
In an LTE environment, the sensitivity of wireless location system receivers to narrowband transmissions, and the resolution of the receivers to wideband transmissions, may be improved by using tailored uplink transmission parameters, thereby increasing location accuracy and decreasing latency in developing a location. A first method for increasing TDOA performance allows LMU receivers to integrate TDOA and/or AOA measurements over longer periods of time, and thus achieve higher sensitivity. This method employs the Semi-Persistent-Scheduling (SPS) feature of the LTE communications system. A second method for increasing TDOA performance allows LMUs to collect signals over a broader bandwidth, and thus achieve higher resolution. This method uses the Sounding Reference Signal (SRS) feature of the LTE system. Using both the SPS and SRS functions for U-TDOA locations provides the benefit of increased sensitivity and greater resolution, thereby providing the potential for significantly improved location performance. |
