| 20100102234 | PAPER-SHEET RECOGNITION APPARATUS, PAPER-SHEET PROCESSING APPARATUS, AND PAPER-SHEET RECOGNITION METHOD - A paper-sheet recognition apparatus that acquires information from a paper sheet and recognizes the paper sheet based on the information. The apparatus includes one or more light emitting units that output first to n-th lights (n>2) of different wavelengths; an emission controller that performs emission control of the light emitting units; a light receiving unit that receive a component of a light, which has been emitted from the light emitting unit and then reflected from and/or transmitted through the paper sheet; and a paper-sheet recognition processor that recognizes the paper sheet by using an optical signal received by the light receiving unit. The emission controller performs the emission control of the light emitting units such that the number of light emissions per one emission cycle with respect each of to the first to n-th lights differs depending on information desired to be used in recognizing the paper sheet. | 04-29-2010 |
| 20120091346 | NDIR-two Beam Gas Analyser And Method For Determining The Concentration Of A Measuring Gas Component in a Gas Mixture by means of Said type of Gas Analyser - The invention relates to a NDIR two beam gas analyser in which infrared radiation is guided by modulation in an alternating manner through a measuring chamber and a reference chamber and is subsequently detected, a measurement signal being produced due to the analysis which determines the concentration of a measurement gas component present in the measurement chamber. The detection and compensation of error effects, in particular modifications on the infrared radiation source or detector arrangement, is simplified as a phase imbalance is produced in the switching of the radiation between the chambers, and the measurement signal is detected in a phase-sensitive manner for modulating the radiation, a measurement signal vector (SF) comprising amplitude information and phase information (Φ | 04-19-2012 |
| 20130075615 | INFRARED SENSOR WITH MULTIPLE SOURCES FOR GAS MEASUREMENT - A closed path infrared sensor includes an enclosure, a first energy source within the enclosure, at least a second energy source within the enclosure, at least one detector system within the enclosure and a mirror system external to the enclosure and spaced from the enclosure. The mirror system reflects energy from the first energy source to the at least one detector system via a first analytical path and reflects energy from the second energy source to the at least one detector system via a second analytical path. Each of the first analytical path and the second analytical path are less than two feet in length. | 03-28-2013 |
| 20140291523 | METHOD AND SYSTEM FOR MEASURING HEAD POSITION OF DRIVER - A method and system that measure the head position of a driver in a vehicle include an infrared lamp that is disposed on a driver B-pillar and transmits an infrared signal and an infrared receiving sensor that is disposed on a passenger A-pillar to receive infrared signal from the infrared lamp. In addition, a plurality of infrared lamps are disposed on the headrest of the driver's seat and transmit infrared signals and an infrared receiving sensor is disposed on a dashboard disposed in front of a steering wheel to receive infrared signals from the infrared lamps on the headrest. A controller operates the infrared lamps to transmit infrared signals and measures the head position of a driver based on infrared signals received by the infrared receiving sensors. | 10-02-2014 |
| 20140374603 | PROFILOMETRY SYSTEMS AND METHODS BASED ON ABSORPTION AND OPTICAL FREQUENCY CONVERSION - The present disclosure provides novel measurement techniques based on moiré techniques and optical frequency conversion. For example, in the IR realm, the configuration can be any moiré configuration, the detector is an IR detector, and the light source can be at any wavelength. The optical configuration, the detector, and the type of light source depend on the physical properties of object/scene and the parameter(s) to be measured. | 12-25-2014 |
| 20150060674 | DEVICE FOR OPTICALLY DETERMINING THE CONCENTRATION OF ALCOHOL AND CARBOHYDRATES IN A LIQUID SAMPLE - Disclosed is a device for optically determining a concentration of alcohol and carbohydrates in a liquid sample. The device includes at least a first and a second light source arranged for exposing the liquid sample in a wavelength range between 750 nm and 1000 nm, a spectrometer arranged to determine a first and a second light intensity by measuring the light from the first and the second light source, a processing unit which is connected to the spectrometer and which is arranged to determine an absorption value of the liquid sample from a comparison of the first and the second light intensity with a reference value. In certain aspects, the device may further include a processing unit that calculates concentrations of alcohol and/or carbohydrates and at least two polarization filters. | 03-05-2015 |

| 20150069249 | Electronic Device with Gesture Detection System and Methods for Using the Gesture Detection System - A method in an electronic device, the method includes projecting infrared (“IR”) light from a plurality of light emitting diodes (“LEDs”) disposed proximate to the perimeter of the electronic device, detecting, by a sensor, IR light originating from at least two of the plurality of LEDs reflected from off of a person, and carrying out a function based on the relative strength of the detected IR light from the LEDs. | 03-12-2015 |
| 20160191055 | REFLECTIVE SWITCH INPUT SURFACE - Example embodiments of a reflective switch and methods for preventing inadvertent actuation of the reflective switch are disclosed. Exemplary embodiments of the reflective switch comprise a plurality of photo emitters that emit light through a translucent zone and a plurality of photo detectors that detect light rays that are reflected back through the translucent zone by an operator input. Upon detecting reflected light rays, the photo detectors send reflective signals to a controller. The controller then monitors whether the unique addresses of the photo detectors are increasing or decreasing and whether the addresses have increased or decreased to a predetermined threshold to merit a change in switch state. An indicia may be configured to notify an operator that a new switch state has been achieved. | 06-30-2016 |
