Patent number: 7187414Abstract: Disclosed is a circuit for stabilizing a high tension voltage of a CRT and a method thereof. A feedback unit receives a cutoff voltage from the CRT. A compensating unit calculates a variation quantity of the cutoff voltage on the basis of the cutoff voltage from the feedback unit.

Accordingly, the circuit for stabilizing the high tension voltage of the CRT and the method thereof can overcome inaccuracy of the high tension voltage compensation due to delay, and cut down the production cost by removing an ABL circuit and a high tension voltage compensating capacitor. Since the ABL circuit is not used, it is also possible to perform partial compensation according to an alternating current variation quantity.Type: GrantFiled: September 12, 2002Date of Patent: March 6, 2007Assignee: Samsung Electronics Co., Ltd.Inventor: Chang-joo Jung

Patent number: 7187445Abstract: A light beam is deflected by refraction and total internal reflection through a first prism, and projected through a first lens onto a scene that is to be scanned. The prism rotates, which varies the deflection angle and scans the beam across the scene along a scan line. Preferably, the successive side surfaces of the prism have different tilt angles relative to the rotation axis, so as to respectively deflect the beam in different deflection planes which cause successive scan lines of the beam across the scene. The emitted beam gives rise to a reflected beam from the scene, which is received through a second lens and deflected onto a photodetector through a second prism congruent to and rotating synchronously with the first prism. This apparatus is suitable as a laser scanning device for an object recognition system or a spacing distance regulation system of a motor vehicle.Type: GrantFiled: January 20, 2004Date of Patent: March 6, 2007Assignee: Automotive Distance Control Systems GmbHInventors: Holger Schanz, Robert Kraus, Wilfried Mehr

A light beam projector causes a plurality of light beams to impinge upon the interfaces of the inner bottom surfaces of one-dimensionally arranged sample wells out of the plurality of sample wells and the thin film layers at various angles of incidence so that total internal reflection conditions are satisfied at each of the interfaces, and the light beams reflected at the respective interfaces are received by a photodetector. A longitudinal tilt measuring system measures a longitudinal tilt of the interface from a predetermined reference position, and a corrected measured value corrected according to the longitudinal tilt measured by the longitudinal tilt measuring system is obtained.Type: GrantFiled: July 26, 2004Date of Patent: March 6, 2007Assignee: Fuji Photo Film Co., Ltd.Inventor: Toshihito Kimura

Patent number: 7187447Abstract: A stepped etalon having a top surface and two bottom surfaces that are parallel to the top surface and are each positioned at different distances from the top surface. Each bottom surface has an edge, wherein the edges face one another and a sloping step is positioned between the two edges so that rays from a beam of light projected onto the top surface of the etalon strike the step at the Brewster angle and pass through the etalon without any light being reflected back therein.Type: GrantFiled: March 30, 2000Date of Patent: March 6, 2007Assignee: Lucent Technologies Inc.Inventors: Michael Alexandrovich, Stephen O'Brien, Richard B.

Patent number: 7187448Abstract: The present invention relates to a fiber-optic gyrometer including a Sagnac interferometer using two light waves propagating in opposite directions in a interferometer loop including a photodetector which delivers an electrical signal Ud representing the light intensity of the interference between the two waves, and for optically phase-shifting the waves controlled by a square-wave modulation signal Um suitable for controlling an optical phase variation at a frequency FO substantially equal to 1/(2to), where to is the propagation time of a wave through the guide. The photodetector is connected to at least a first sampling circuit and a second sampling circuit which are controlled in phase opposition by a clock. The gyrometer includes a means for inverting the phase of the clock at a frequency f, which is very much less than the frequency FO.Type: GrantFiled: April 30, 2002Date of Patent: March 6, 2007Assignee: ThalesInventor: Jean-Claude Lehureau

Patent number: 7187451Abstract: An apparatus for measuring a two-dimensional displacement is disclosed and includes a laser light source, a collimator lens, a beam splitter, a plurality of staggered conjugate optic lens and a plurality of interference optical dephasing modules. The laser light source provides a laser light incident on the collimator lens to generate collimated laser beams.

Patent number: 7187455Abstract: A method and apparatus for measuring and calibrating the measurement of small volumes of liquids. The small volumes of liquid are typically dispensed from liquid delivery devices, the delivery device often having multiple channels to analyze many samples at once. The liquid samples are delivered to one or more cells, typically in a multi-well plate, and positioned in a spectrophotometer for determining an absorbance of a chromophore in the liquid sample. Based upon an absorbance measurement and the concentration of the chromophore, a path length of the liquid sample is determined, from which a volume of the sample may be calculated. The method and apparatus provide various means for correcting for differences in the dimensions and/or other factors causing a non-linear deviation from the Beer-Lambert law. A system or kit may be provided including sets of sample solutions of varying dilution ranges for calibrating different liquid volumes.Type: GrantFiled: April 19, 2004Date of Patent: March 6, 2007Assignee: Artel, Inc.Inventor: Richard H.
