  • Patent number: 8189547
    Abstract: A self-configuration method for access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more transmitting access devices, the beacons being transmitted and received using a plurality of different channels available to the wireless network. The method records radio frequency (RF) data associated with the received beacons, and processes the RF data to select, from the plurality of different channels, a respective channel for each of the access devices. In addition, the RF data is processed to adjust transmit power levels for the access devices. The selected channels and adjusted transmit power levels are then used as configuration settings for the access devices.

  • Publication number: 20120068497
    Abstract: Magnesium alloy tube members have the potential to reduce weight in automotive vehicle body structures and other applications but they tend to fragment and fail under compressive stress loads applied end-to-end along the longitudinal axis of the tube. It is found that, when the outside surface of the tube is tightly wrapped with fibers (for example, glass fibers or other suitable fibers) and, optionally, resin bonded to the tube surface, the capacity of the magnesium alloy tube to withstand and absorb compressive loads is greatly increased.

  • Publication number: 20120063963
    Abstract: Provided is a new catalyst capable of removing carbon monoxide economically without adding particular reaction gas externally. Also provided are a process for producing and an apparatus using such a catalyst. Impregnation of a Ni—Al composite oxide precursor of a nonstoichiometric composition prepared by the solution-spray plasma technique with a ruthenium salt to be supported and performing reduction treatment allows CO methanation reaction to selectively proceed even in the high-temperature range in which CO2 methanation reaction and reverse water-gas-shift reaction proceed preferentially with conventional catalysts. Selective CO methanation reaction occurs reproducibly with another Ni—Al composite oxide precursor or an additive metallic species.
