| 20110298547 | Method, system and apparatus for accurate and stable LC-based reference oscillators - A substantially temperature-independent LC-based oscillator is achieved using an LC tank that generates a tank oscillation at a phase substantially equal to a temperature null phase. The temperature null phase is a phase of the LC tank at which variations in frequency of an output oscillation of the LC-based oscillator with temperature changes are minimized. The LC-based oscillator further includes frequency stabilizer circuitry coupled to the LC tank to cause the LC tank to oscillate at the phase substantially equal to the temperature null phase. | 12-08-2011 |
| 20110222067 | TECHNIQUE TO DETERMINE MIRROR POSITION IN OPTICAL INTERFEROMETERS - A Micro Electro-Mechanical System (MEMS) interferometer system utilizes a capacitive sensing circuit to determine the position of a moveable minor. An electrostatic MEMS actuator is coupled to the moveable minor to cause a displacement thereof. The capacitive sensing circuit senses the current capacitance of the MEMS actuator and determines the position of the moveable minor based on the current capacitance of the MEMS actuator. | 09-15-2011 |
| 20110176138 | INTERFEROMETER WITH VARIABLE OPTICAL PATH LENGTH REFERENCE MIRROR AND APPLICATIONS THEREOF - An interferometer includes a variable optical path length reference mirror to produce a final interferogram from a combination of interferograms.

A MEMS spectrometer/interferometer includes a beam splitter formed on a first surface of a first medium at an interface between the first medium and a second medium, a first mirror formed on a second surface of the first medium, a second mirror formed on a third surface of the first medium and balancing interfaces designed to minimize both a difference in tilt angles between the surfaces and a difference in phase errors between beams reflected from the first and second mirrors. | 03-10-2011 |
| 20100315647 | System, Method and Apparatus for a Micromachined Interferometer Using Optical Splitting - A Mach-Zehnder MEMS interferometer is achieved using two half plane beam splitters formed at respective edges of a first medium. The first beam splitter is optically coupled to receive an incident beam and operates to split the incident beam into two beams, a first one propagating in the first medium towards the second beam splitter and a second one propagating in a second medium. A moveable mirror in the second medium reflects the second beam back towards the second beam splitter to cause interference of the two beams. | 12-16-2010 |
| 20100265512 | OPTO-MECHANICAL OPTICAL PATH RETARDATION MULTIPLIER FOR OPTICAL MEMS APPLICATIONS - An optical Micro Electro-Mechanical System (MEMS) device provides an optical path retardation multiplier. The MEMS device includes a moveable corner cube reflector, a fixed minor and a MEMS actuator. The moveable corner cube reflector is optically coupled to receive an incident beam and reflect the incident beam through 180 degrees towards the fixed mirror. The fixed minor is optically coupled to reflect a reflected beam back towards the moveable corner cube reflector along a reverse path of the incident beam. The MEMS actuator is coupled to the moveable corner cube reflector to cause a displacement of the moveable corner cube reflector to extend an optical path length of the reflected beam. | 10-21-2010 |
| 20100265382 | ULTRA-WIDE ANGLE MEMS SCANNER ARCHITECTURE - An optical microscanner achieves wide rotation angles utilizing a curved reflector. The optical microscanner includes a moveable mirror for receiving an incident beam and reflecting the incident beam to produce a reflected beam and a Micro Electro-Mechanical System (MEMS) actuator that causes a linear displacement of the moveable minor. The curved reflector produces an angular rotation of the reflected beam based on the linear displacement of the moveable mirror. | 10-21-2010 |
| 20100264777 | LONG RANGE TRAVEL MEMS ACTUATOR - An electrostatic comb drive actuator for a MEMS device includes a flexure spring assembly and first and second comb drive assemblies, each coupled to the flexure spring assembly on opposing sides thereof. Each of the first and second comb assemblies includes fixed comb drive fingers and moveable comb drive fingers coupled to the flexure spring assembly and extending towards the fixed comb drive fingers. The comb drive fingers are divided equally between the first and second comb drive assemblies and placed symmetrically about a symmetry axis of the flexure spring assembly. When electrically energized, the moveable comb drive fingers of both the first and second comb drive assemblies simultaneously move towards the fixed comb drive fingers of the first and second comb drive assemblies. | 10-21-2010 |
