Abstract: An Integrated, Self-Optimizing, Multi-Parameter/Multi-Variable Point-to-Multipoint Communication System provides integrated adaptive and dynamic responsiveness for communication parameters related to multiple characteristics of wireless communication links for a single sender, a single receiver, and for sets of multiple senders and multiple receivers. The method and system are self-optimizing and adaptively and dynamically respond to results of attempts to optimize parameters related to multiple characteristics of wireless communication links. Multiple characteristics of wireless communication links are optimized simultaneously, in that the optimal set of values for a plurality of N characteristics, rather than N individual optimal values for each characteristic, is adaptively and dynamically selected. A wireless PHY layer and wireless MAC layer collectively include a set of communication parameters, which are adaptively modified by a BSC for communication with a plurality of CPE.

Abstract: A system that adapts wireless link parameters for a wireless communication link. A measure is determined of errors occurring in communication over a wireless link. In a case that the measure of errors corresponds to more errors than a first predetermined threshold, communication changes from a first set of wireless link parameters to a second set of wireless link parameters. The second set of wireless link parameters corresponds to higher error tolerance than the first set of wireless link parameters. In a case that the measure of errors corresponds to fewer errors than a second predetermined threshold, communication changes from the first set of wireless link parameters to a third set of wireless link parameters. The third set of wireless link parameters corresponds to lower error tolerance than the first set of wireless link parameters. Preferably, the measure of errors is determined by monitoring a number of NACK messages and a number of ACK messages that occur.

Abstract: The present invention provides electrode assemblies for LIC imagers that maximize ion collection and the electric field for the minimum bias voltage. To achieve this optimization the ion collection is confined to small regions. Due to this limited ion collection region, high neutralization efficiencies and fast sweep-out times can be obtained. Furthermore, with an electrode separation of approximately 0.1 millimeters, pulse voltages of less than 100 volts can be used. Low voltages result in improved reliability, longer system life, and lower safety risks.

Abstract: An NMR receiver includes an analog to digital converter for sampling a nuclear magnetic resonance probe output signal at a frequency that is less than the probe signal center frequency and is at least twice the probe signal bandwidth.
