Abstract: The network device includes a transceiver, a pattern generation unit and a pattern recognition unit. The transceiver connects to a communications medium. The pattern generation unit connects to the transceiver. The pattern generation unit is configured to generate a first code word in response to a self-test signal. The pattern recognition unit connects to the communications medium and a network entity. The pattern recognition unit is configured to receive the first code word from the transceiver and to determine whether the first code word includes a loop back pattern. The pattern recognition unit is configured to generate a second code based upon the first code word and to include in the second code word a pattern different from the first code word.

Abstract: Applicants have devised a highly effective, convenient, and expeditious genetic transformation system for filamentous fungi, such as Agaricus bisporus. The preferred method uses an Agrobacterium-mediated transformation protocol. The critical features of this protocol include co-cultivation of the bacterium with fruit body tissue instead of spores. In a preferred embodiment, even higher transformation efficiencies were observed with the use of a homologous promoter in the polynucleotide expression construct in order to drive gene expression.

Abstract: A surgical tool with a rigid body including a needle portion for entering tissue includes a fluid flow channel formed therethrough. A sensor is integrally formed on the tool to detect changing conditions (pressure and/or flow) in the channel. The sensor signal may be used to provide feedback control of pumping of fluid through the channel. The tool may be a micromachined silicon tool with the sensor integrally formed thereon from a silicon nitrate membrane and polysilicon resistors. The tool may be an ultrasonically activated cutting tool, which may be bonded to a package at a node thereof.

Abstract: Methods and circuits utilizing a two stage adaptation algorithm to determine the optimal code for an equalizer to compensate a received signal is disclosed. In the first stage, a coarse tuning algorithm is used to choose a range of codes based on the amplitude of the received signal. The chosen codes will be used as reference points in the second stage. In the second stage, a fine tuning algorithm is used to select a code in the range of reference codes determined in stage one. The fine tuning algorithm looks to the status of the data lock signal generated by the clock recovery circuit. If the data lock signal does not indicate a lock, the fine tuning algorithm cycles through the range of reference codes. If the data lock signal indicates a lock, then that particular code is continued to be used for the equalizer.
