| 20100002950 | Methods and apparatus for wavefront manipulations and improved 3-D measurements - Methods and apparatus to perform wavefront analysis, including phase and amplitude information, and 3D measurements in optical systems, and in particular those based on analyzing the output of an intermediate plane, such as an image plane, of an optical system. Measurement of surface topography in the presence of thin film coatings, or of the individual layers of a multilayered structure is described. Multi-wavelength analysis in combination with phase and amplitude mapping is utilized. Methods of improving phase and surface topography measurements by wavefront propagation and refocusing, using virtual wavefront propagation based on solutions of Maxwell's equations are described. Reduction of coherence noise in optical imaging systems is achieved by such phase manipulation methods, or by methods utilizing a combination of wideband and coherent sources. The methods are applied to Integrated Circuit inspection, to improve overlay measurement techniques, by improving contrast or by 3-D imaging, in single shot imaging.

| 20110115666 | Highway Speed Ground Penetrating Radar System Utilizing Air-Launched Antenna and Method of Use - Embodiments of the disclosed technology comprise an air-launched antenna system with interference-rejection technology that operates in analog hardware as well as by way of a digital filtering technique. Using an inline analog hardware filter combined with a digital filter, to determine transversal (and/or recursive) coefficients, in a calibration phase, a measurement system may be configured to remove interference and the effects (such as a delay or temperature variation) which result from use of an analog filter. In this manner, the resulting measurements of a composition of road surface are more accurate and useful. | 05-19-2011 |
| 20110115667 | Ultra-wideband Radar Waveform Calibration for Measurements of a Heterogeneous Material - Embodiments of the disclosed technology comprise a ground penetrating radio device and methods of use for obtaining greater resolution. This is achieved by measuring the composition/reflection off a homogeneous material (e.g., metal plate), determining coefficients to correct the measured/reflection in order to make the measurements look like an idealized reference signal, and then using these coefficients in a digital filter to correct measurements/a reflection off a heterogeneous material, such as a road surface. In this manner, the composition of the heterogeneous material is determined with greater accuracy. | 05-19-2011 |

| 20100272208 | IMBALANCE COMPENSATION FOR DIRECT CONVERSION COMMUNICATION SYSTEMS - Most modern integrated circuit transceivers, especially wireless LAN, utilize a direct conversion radio architecture, which is highly advantageous from the perspectives of cost and flexibility, there exist several performance impairments, including gain and phase imbalances between the in-phase (I) and quadrature (Q) of a transmitter or receiver. Disclosed herein is a signal processing methodology and system for compensation of I/Q imbalance for a direct conversion packet-switched OFDM communications system. The imbalance, which accounts for transmitter I/Q imbalance, RX I/Q imbalance, phase/frequency error, and dispersive multipath fading. Both frequency dependent I/Q imbalance and frequency independent cases are considered, covering both wideband and narrowband modulation. The proposed estimation algorithms operate within the fully compliant framework of existing multi-user OFDM radio standards (WLAN, LTE, WimAX). These algorithms accurately estimate and correct transceiver I/Q imbalance on a packet-by-packet basis, all within the receiver's digital baseband. | 10-28-2010 |

| 20090011279 | MANUFACTURED CONSTRUCTION BOARD WITH TEXTURE - A manufactured construction board is formed from a composition that may include magnesium oxide, magnesium chloride, a binding agent (e.g., perlite), wood shavings, recycled board scraps, and water. The construction board further includes fiberglass and polyester paper sheets on opposite sides of the construction board. A method of fabricating the construction board is also disclosed to include mixing magnesium chloride with water to form a solution, mixing the solution with magnesium oxide, perlite and a binding agent to form a paste, and pouring the paste onto a mold to form a construction board. The paste is poured onto a mold which is then passed through a series of rollers to spread out the paste evenly across the mold and to form the paste into the desired thickness. The resulting construction board is fire and water resistant and much more durable than conventional sheetrock. | 01-08-2009 |

| 20100288015 | CANTILEVERED PROBE DETECTOR WITH PIEZOELECTRIC ELEMENT - A disclosed chemical detection system for detecting a target material, such as an explosive material, can include a cantilevered probe, a probe heater coupled to the cantilevered probe, and a piezoelectric element disposed on the cantilevered probe. The piezoelectric element can be configured as a detector and/or an actuator. Detection can include, for example, detecting a movement of the cantilevered probe or a property of the cantilevered probe. The movement or a change in the property of the cantilevered probe can occur, for example, by adsorption of the target material, desorption of the target material, reaction of the target material and/or phase change of the target material. Examples of detectable movements and properties include temperature shifts, impedance shifts, and resonant frequency shifts of the cantilevered probe. The overall chemical detection system can be incorporated, for example, into a handheld explosive material detection system. | 11-18-2010 |
