Patent number: 7889349Abstract: The present invention provides improved methods and apparatuses for accurate measurements using interferometers. A functional relationship between the optical path difference and time is determined from a reference signal from an interferometer. The times at which the interferometer had specific optical path differences can be determined from the functional relationship. Those times can then be used to select times at which the spectroscopic signal from the interferometer was produced at the specific optical path differences. The invention can be applied, as examples, to maintain instrument calibration, and to transfer or compare calibrations or measurements across different interferometers.Type: GrantFiled: November 16, 2006Date of Patent: February 15, 2011Assignee: TruTouch Technologies, Inc.Inventors: Trent Ridder, Ben ver Steeg, Michael Haass, John D.

Publication number: 20060239547Abstract: The present invention relates to the use of optical skin measurements to determine skin properties such as surface topography, hydration, elasticity, pigmentation intensity or uniformity, dermal thickness, dermal perfusion, presence or concentration or composition of oil on or near the surface, and apparent age of the skin. An apparatus according to the present invention can comprise a skin positioning system for positioning the skin relative to other parts of the apparatus. An illumination system, adapted to produce illumination radiation, can mount with the skin positioning system such that illumination radiation impinges on a first portion of the skin at a first determined angle thereto. A detection system can mount with the skin positioning system such that radiation from a second portion of the skin at a second determined angle therefrom impinges on the detector.Type: ApplicationFiled: April 19, 2006Publication date: October 26, 2006Inventors: M.

Publication number: 20020167174Abstract: A generator system for providing power to communications equipment. The generator comprises an engine, an alternator, a rectifier, and a cable connected between the rectifier and the communications equipment. The engine converts fuel energy into rotation of an output shaft. The alternator is operatively connected to the output shaft to convert the rotation of the output shaft into a raw alternating current power signal. The rectifier generates a direct current power signal based on the raw power signal. The generator preferably comprises a controller for controlling the engine based on the load requirements of the communications equipment. A select switch may be provided to cause the controller to control the rectifier to generate the direct current power signal at first and second predetermined levels.Type: ApplicationFiled: May 9, 2002Publication date: November 14, 2002Inventors: Michael A. Haass, Gilford A. McPhillips, David L. Stricker
