Abstract: Embodiments may provide for multi-attribute auctioning. Bids and offers which comprise non-price attributes may be received by an auction service, such as web content bids and offers for space on webpages. The service may evaluate attributes of bids and offers in a quantitative manner, developing a value for the bid and offer that includes both price information and other non-price attributes. Valuation may be performed through the use of willingness-to-pay functions which, based on a knowledge of an agent, may determine a numerical value for that agent's willingness to pay according to the non-price attributes. The result from evaluating this function may then be used to determine which auction bids and offers may be matched. The bid or offer can include one or more probability distributions for future performance, based on the published statistics about past performance of agents. Other embodiments may be described and claimed.

Abstract: A directional and interleaved wireless mesh network is described where mesh nodes have directional antennas facing in horizontally orthogonal directions. The antennas can be focused to have a beam width of less than ninety degrees in order to achieve greater strength of signal and radiation. Each mesh node can have two radios that communicate on separate channels, such that packets propagated through the mesh network can utilize either channel in order to hop from one node to the next. Each radio can be connected to four orthogonally directed antennas in order to enable communication with adjacent nodes. Alternatively, a separate independent radio can be connected to each antenna in order to achieve greater simultaneity of transmission and reception to the node. For example, two such radio-antenna combinations can be facing in each of the four orthogonal directions, each of the two combinations operating on a different RF channel.

Abstract: An apparatus and method to improve broadband amplifier linearization. The present circuits make use of pre-distortion techniques to improve the 3rd order distortion of an amplifier to reduce the amount of DC power required to achieve a given system requirement. In addition, the amplifiers have broadband characteristics which lend themselves to simplified pre-distortion. A pre-distortion linearizer circuit is connected across the input terminals of an amplifier. The linearizer circuit includes multiple diodes to improve the clipping performance of the linearizer. In addition, RC circuits align the phase of the linearizer distortion to be opposite that of the amplifier.
