| 20090040516 | SPECTROSCOPIC SYSTEM - A spectroscopic system having a coded aperture as a gating device. Light of a Raman scattering may enter the system and encounter a mask gate. The mask may have a matrix of micro mirrors some of which pass light on to a diffraction grating when the gate is on. Some of the mirrors will not pass on light thereby resulting in coded light to the grating. If the gate is off, then no light is passed on to the grating. The grating may pass the coded and spectrally spread light on to a detector array. The array signals representing the light on the array may go to a processor so one can obtain information about the target that emanated the Raman scatter when impinged by a light beam. | 02-12-2009 |
| 20090147240 | METHOD AND SYSTEM FOR EYE SAFETY IN OPTICAL SENSOR SYSTEMS - One embodiment of the application provides a method and system for measuring a range to a target using a ranging system by measuring the time of flight of a ranging signal to and from the target, the first ranging signal having an energy sufficient to locate the target and detecting the target using a detection system generating a target detection signal, the target detection signal having a peak energy determined by the range to the target measured by the first detection system. | 06-11-2009 |
| 20090219524 | METHOD AND APPARATUS FOR CONTROLLED RAMAN SPECTROMETER - One embodiments includes a method that includes enabling an excitation laser during an excitation period, after a timed delay following the first excitation period, monitoring a photon scattering caused by the excitation laser, analyzing the photon scattering, automatically adjusting the timed delay to a modified timed delay based on the analyzed photon scattering and following the modified timed delay, enabling a Raman spectrometer to monitor Raman scattering caused by the excitation laser during a Raman monitoring period. | 09-03-2009 |
| 20090273770 | SYSTEMS AND METHODS FOR SAFE LASER IMAGING, DETECTION AND RANGING (LIDAR) OPERATION - A Laser Imaging, Detection and Ranging (LIDAR) system that automatically adjusts laser output so that no eye damage occurs to human targets. In one example, a component automatically measures range to targets in a field of view and determines the closest targets based on the measured range. A laser device outputs a laser beam and a controller adjusts one of pulse repetition frequency, power, or pulse duration of the laser device based on the measured range of the closest target in order to comply with a predefined eye safety model. | 11-05-2009 |
| 20100001355 | RF MEMS Switch - An RF MEMS switch having a beam composed of a material having a high resistivity and a large Young's modulus may provide a large restoring force, a large electrostatic force at a low actuation voltage, and good isolation between signal input and output. RF MEMS switch reliability may be improved by reducing failures due to stiction by providing a large restoring force. A reliable contact may be provided with a large electrostatic force. | 01-07-2010 |
