|20110180654||PRECISION GUIDED MUNITIONS - A guidance system for actively guiding a projectile, such as a bullet after it has been fired from a gun. The guidance system includes a radar unit that includes a plurality of receiver arrays. An optical scope is also mounted to the gun for optically sighting a target. An inertial measurement unit provided on the gun locks onto the target after it has been sighted by the scope, and provides a reference location at the center of the receiver arrays from which the bullet can be directed. The receiver arrays receive radar monopulse beacon signals from the bullet. The signals from the bullet are used to identify the position of the bullet and the roll of the bullet. The signals sent to the bullet provide flight correction information that is processed on the bullet, and used to control actuators that move steering devices on the bullet.||07-28-2011|
|20110148707||VERTICALLY INTEGRATED PHASED ARRAY - A vertically integrated electronically steered phased array that employs beamsteering using a programmable phase locked loop including a local oscillator. The local oscillator provides an oscillator signal that is converted to an RF signal that can be either up-converted for a transmit operation or down-converted for a receive operation. The relative off-set between independently generated local oscillator signals forms the basis of the off-set phase required for a phased array. The absolute measure of off-set phase is referenced to a globally distributed clock signal that aligns the zero degree phase shift of the oscillator.||06-23-2011|

|20090246929||MEMBRANE SUSPENDED MEMS STRUCTURES - A method for micro-machining a varactor that is part of a membrane suspended MEMS tunable filter. In one non-limiting embodiment, the method includes providing a main substrate; depositing a membrane on the main substrate; depositing and patterning a plurality of sacrificial photoresist layers at predetermined times during the fabrication of the varactor; depositing metal layers that define a fabricated varactor structure enclosed within photoresist; coupling a carrier substrate to the fabricated structure opposite to the main substrate using a release layer; etching a central portion of the main substrate to expose the membrane; removing the carrier substrate by dissolving the release layer in a material that attacks the release layer but does not dissolve the photoresist; and removing the photoresist layers to provide a released varactor.||10-01-2009|
|20080309567||Hand Held Reader Antenna for RFID and Tire Pressure Monitoring System - An antenna assembly that has particular application for a hand held reader that interrogates sensors embedded within a vehicle tire, such as RFID sensors and tire pressure sensors. In one embodiment, the antenna assembly includes a first antenna operating in the 432-435 MHz range that employs a meander-line slot that provides increased antenna cross-polarization so that the sensor can be interrogated regardless of the antenna orientation and polarization. The antenna assembly also includes two RFID antennas that operate in the 902-928 MHz range that are planar antenna that make the antenna bi-directional, polarization free and a wide enough bandwidth for the RFID interrogation.||12-18-2008|
|20080309545||Speed Measuring Device Including Fresnel Zone Plate Lens Antenna - A speed measuring device that employs a Fresnel zone plate lens antenna. The Fresnel lens antenna is mounted to one end of a low profile collection housing, typically cylindrical in configuration. An opposite end of the collection housing includes a back plate having an opening. A transceiver unit is mounted to the outside surface of the back plate so that a transmitter and a detector within the transceiver are in communication with the opening. A signal is transmitted from the transceiver unit through the opening, and is directed by the lens antenna. A reflected signal is received and focused by the lens antenna, and collected by the housing to be directed through the opening to the transceiver.||12-18-2008|
|20080252521||Vertically Integrated Transceiver Array - A transceiver array that employs vertically integrated circuits in one or more wafers. The array includes a digital wafer having digital circuits. A plurality of RF cubes are formed to the digital wafer, where each RF cube includes an antenna wafer and at least one lower wafer, and where each RF cube represents a separate channel of the array. The antenna wafer includes a patch antenna and a resonating cavity. The at least one lower wafer includes high frequency RF integrated circuits and intermediate frequency RF integrated circuits. The array has application as a front-end for a digital beam-forming system.||10-16-2008|
|20080252401||Evanescent Mode Resonator Including Tunable Capacitive Post - An evanescent mode resonator including a cavity formed in a substrate of semiconductor material. The resonator includes a capacitive post positioned within the cavity, and a tuning element positioned within the wall of the cavity proximate to the capacitive post, where a gap between the flexible element and the post sets the tuning of the resonator.||10-16-2008|
