| 20110138183 | METHOD FOR ENSURING SECURITY AND PRIVACY IN A WIRELESS COGNITIVE NETWORK - In some embodiments, authentication, confidentiality, and privacy are enhanced for a wireless network of cognitive radios by encryption of network management and control messages as well as data traffic, thereby protecting information pertaining to node identification, node location, node-sensed incumbent transmissions, CRN frequency channel selections, and such like.

| 20090072950 | TRANSPONDER WITH STABILIZED OSCILLATOR - A coherent RFID tag design having no internal power source is disclosed. The design exhibits a longer detection range and less interference relative to conventional tag designs. The coherent RFID tag design operates in a locked or stabilized fashion, in that the frequency at which energy is parasitically coupled to the RFID tag (via its antenna) is the same as the frequency at which the RFID tag transmits information utilizing the same antenna. The RFID tag design allows a greater number of RFID tags to be deployed, without causing cross-tag interference issues and the like. | 03-19-2009 |
| 20090067553 | JOINT SYMBOL, AMPLITUDE, AND RATE ESTIMATOR - The system in one embodiment relates to tightly integrating parameter estimation, symbol hypothesis testing, decoding, and rate identification. The present invention provides Turbo-decoding for joint signal demodulation based on an iterative decoding solution that exploits error correction codes. The system iteratively couples an initial amplitude estimator, a symbol estimator, a bank of decoders, and a joint amplitude estimator to produce the symbol estimates. | 03-12-2009 |
| 20090041096 | EFFICIENT SYNCHRONIZATION OF A SPREAD SPECTRUM SIGNAL IN THE PRESENCE OF DELAY AND FREQUENCY UNCERTAINTY - Implementations for the synchronization of a spread spectrum signal in the presence of delay and frequency uncertainty. According to one embodiment, there is a signal processing technique that combines coherent integration with a Fast Fourier Transform (FFT). Coherent integration with the direct sequence code is achieved through the use of shift registers, code modulators, and integrators, and applied to subsequences of the spreading code. Subsequences can then be combined via an FFT to achieve further coherent integration and to simultaneously deal with frequency uncertainty. | 02-12-2009 |
| 20090039197 | Optically Guided Munition Control System and Method - An optically guided munition and control system has a replacement fuse assembly mounted on the front of a munition body or shell casing. An optical seeker subsystem detects an illuminated target and supplies signals to a processor. The processor develops steering commands sent to a flight control subsystem having a plurality of guidance canards which are actuated by drive motors through gear assemblies. The roll of the munition is established and left/right and up/down steering commands are sent to the canard drive motors based upon the optical seeker subsystem detection of the target illuminator. Range adjustment is based upon bore sight lockdown angle and cross range control is based upon left/right centering error. A code is contained in the optical radiation received from the illuminated target which must be validated by a preset code in the system processor to arm the munition. | 02-12-2009 |
| 20090034312 | SINGLE-EVENT UPSET IMMUNE STATIC RANDOM ACCESS MEMORY CELL CIRCUIT, SYSTEM, AND METHOD - A circuit and method are provided in which a six-transistor (6-T) SRAM memory cell is hardened to single-event upsets by adding isolation-field effect transistors (“iso-fets”) connected between the reference voltage Vdd and the field-effect transistors (“fets”) respectively corresponding to first and second inverters of the memory cell. According to certain embodiments, the control gates of first and second P-iso-fets are respectively tied to the control gates of first and second pull-up P-fets. According to certain embodiments, first and second N-iso-fets are connected between the output nodes of the memory cell and the pull-down N-fets respectively corresponding to the first and second inverters. The control gates of the first and second N-iso-fets are respectively tied to the control gates of the first and second pull-down N-fets. Again according to certain embodiments, one or more of the iso-fets are physically removed from the proximity of other transistors which comprise the memory cell. | 02-05-2009 |
| 20080298251 | INTEGRATING LOCAL CONGESTION AND PATH INTERFERENCE INTO QoS ROUTING FOR WIRELESS MOBILE AD HOC NETWORKS - A method and apparatus is provided for using a distributed multi-path QoS-aware routing scheme that considers basic MANET characteristics to meet transport service requirements of real-time applications and makes use of multiple discovered paths to calculate a next-hop decision. The QoS Routing scheme superimposes distributed neighborhood congestion, neighborhood density, and link stability and delay information over the multiple discovered paths when the next-hop decision is calculated. | 12-04-2008 |
