|20140067739||REDUCTION OR ELIMINATION OF TRAINING FOR ADAPTIVE FILTERS AND NEURAL NETWORKS THROUGH LOOK-UP TABLE - A system and method of reducing or eliminating training for adaptive receiver and neural networks is disclosed. The adaptive filter or neural network is pre-training using simulation or empirically received data and a took-up table is created. Coefficient instantiation from the receiver for ail permutations of the key parameters of training data are stored along with the key parameters within the look-up table. After creating the look-up table, the key parameters of the signal to be decoded are estimated. The coefficient of filter or neural network for the estimated key parameters is obtained by accessing the loop-up table. The demodulated signal is produced by setting the filter or neural network coefficents to coefficient values obtained from the look-up table. For slow varying key parameters, the coefficients from the lookup table are occasionally replaced instead of implementing the adaptive filter or neural network.||03-06-2014|
|20130230951||ASYMMETRICALLY RECESSED HIGH-POWER AND HIGH-GAIN ULTRA-SHORT GATE HEMT DEVICE - A high-power and high-gain ultra-short gate HEMT device has exceptional gain and an exceptionally high breakdown voltage provided by an increased width asymmetric recess for the gate electrode, by a composite channel layer including a thin indium arsenide layer embedded in the indium gallium arsenide channel layer and by double doping through the use of an additional silicon doping spike. The improved transistor has an exceptional 14 dB gain at 110 GHz and exhibits an exceptionally high 3.5-4 V breakdown voltage, thus to provide high gain, high-power and ultra-high frequency in an ultra-short gate device.||09-05-2013|
|20120161771||LONG DISTANCE EXPLOSIVE DETECTION USING NUCLEAR QUADRUPOLE RESONANCE AND ONE OR MORE MONOPOLES - Rather than using balanced transmission lines the stimulated response due to nuclear quadrupole resonance can be detected using a single monopole, with multiple monopoles improving substance detection.||06-28-2012|
|20120100809||VARIABLE TIME DELAY CONTROL STRUCTURE FOR CHANNEL MATCHING - A cosite interference cancellation system is provided for improved rejection of a signal coupled from a transmission antenna into a local receive antenna in the presence of local multipath. The cosite interference cancellation system and associated method advantageously provide improved signal rejection by continuously controlling (adjusting) a matching time delay to reduce cosite interference.||04-26-2012|
|20110115673||SYSTEM AND METHOD FOR INTERROGATING A TARGET USING POLARIZED WAVES - A system and method for communication that could be used in an identification friend or foe system. The method comprises generating a first message by a processor and controlling a beam steerer to deflect transmitted waves toward a first angle. The method further comprises transmitting the first message through an antenna in communication with the beam steerer toward the spatial angle. The method further comprises controlling the beam steerer to deflect waves received from the spatial angle. The method further comprises receiving a responsive wave at the antenna through the beam steerer at the spatial angle, the responsive wave including a second message responsive to the first message.||05-19-2011|
|20110059709||Self-Optimizing Integrated RF Converter - Techniques are disclosed for optimization of RF converters. The techniques can be employed, for instance, in RF converters implemented in semiconductor materials (system-on-chip, or chip set) or with discrete components on a printed circuit board. In any such cases, the RF converter system can be configured with one or more actuators to adjust performance, one or more sensor to assess the performance (e.g., linearity of RF converter) and parameters of interest (e.g., ambient temperature, and a control block for controlling the sensors and actuators. The configuration allows the RF converter to autonomously self-optimize for linearity or other parameters of interest such as gain, noise figure, and dynamic range, across a broad range of variables.||03-10-2011|
|20100227622||RESOURCE ALLOCATION IN CO-EXISTENCE MODE - Techniques are disclosed that allow for resource allocation during situations requiring co-existence in cognitive radios. Even under situations of bandwidth scarcity, the techniques allow various users to be guaranteed quality of service (QoS) by proper distribution and allocation of resources. The techniques allow wireless communication systems to operate in a normal mode and a co-existence mode. In the co-existence mode of operation, sub-frame creation, sharing and zone formation schemes are implemented that enable the existing underlying frame structure to remain intact and inter-operable with the legacy systems and at the same time, provide a guaranteed QoS. The zones effectively create partitions in space, time and frequency, which result in interference avoidance and allow various users in neighboring cells to communicate on the same frequencies.||09-09-2010|
|20100224763||SELECTIVE CHANNEL CHARGING FOR MICROCHANNEL PLATE - Techniques are disclosed that can be used to increase the dynamic range of a microchannel plate (MCP) device, thereby eliminating the need for conventional techniques such as gating. In one example embodiment, an MCP device is provided that includes a plurality of channels, each channel for amplifying a photoelectron input to the channel and for producing an electron cloud at its output. The device further includes one or more charging switches associated with each channel for allowing charging current to flow so as to charge that channel in response to producing an electron cloud. In some such example cases, the plurality of channels and the one or more switches are implemented in silicon, and the one or more charging switches turn on only in the presence of the electron cloud produced at the corresponding channel output.||09-09-2010|
|20090296982||FUSION OF IMAGE BLOCK ADJUSTMENTS FOR THE GENERATION OF A GROUND CONTROL NETWORK - A method for fusion of image block adjustments for the generation of a ground control network constituting a Metric Information Network (MIN). Utilizing the subject. fusion algorithm it is possible to duplicate the results of an extremely large simultaneous image block adjustment by sequentially performing smaller image block adjustments on small overlapping areas of interest and taking the results to update a metric information network. Note, intermediate results for less than all the imagery provide usable updates to the metric information network. The result of the infusion of sequential image block adjustments into the metric information network is that one can obtain the accuracy provided by an extremely large single image block adjustment, and do so in manageable chunks or segments involving conventional computer resources.||12-03-2009|
