| 20100245802 | Optical Sensor System Including Series Connected Light Emitting Diodes - An optical sensor system having a light source comprising a plurality of series connected light emitting diodes (LEDs). The series connected LEDs may be switched at a predetermined frequency. | 09-30-2010 |
| 20110051121 | TELESCOPE WITH A WIDE FIELD OF VIEW INTERNAL OPTICAL SCANNER - A telescope with internal scanner utilizing either a single optical wedge scanner or a dual optical wedge scanner and a controller arranged to control a synchronous rotation of the first and/or second optical wedges, the wedges constructed and arranged to scan light redirected by topological surfaces and/or volumetric scatterers. The telescope with internal scanner further incorporates a first converging optical element that receives the redirected light and transmits the redirected light to the scanner, and a second converging optical element within the light path between the first optical element and the scanner arranged to reduce an area of impact on the scanner of the beam collected by the first optical element. | 03-03-2011 |
| 20140327903 | DISTANCE MEASUREMENT DEVICE - In a distance measurement device of an embodiment, a light source emits modulation light in a first charge transfer cycle, and emission of the modulation light of the light source is stopped in a second charge transfer cycle. In each of the first and second charge transfer cycles, the charges generated in a photosensitive region are distributed to a first accumulation region and a second accumulation region. A first value is obtained based on readout values corresponding to amounts of accumulated charges of the first accumulation region. A second value is obtained based on readout values corresponding to amounts of accumulated charges of the second accumulation region. A distance is calculated based on the first value and the second value. | 11-06-2014 |
| 20150116695 | LIGHT RADAR SIGNAL PROCESSING APPARATUS, SYSTEMS AND METHODS - Samples of a light radar (“LIDAR”) return signal are stored in an analog circular buffer following the transmission of a LIDAR pulse. Sampling continues for a fixed period of time or number of samples during a post-trigger sampling period after the occurrence of a trigger signal from a trigger circuit. The trigger circuit indicates the receipt of a return pulse associated with a target object based upon one or more return signal characteristics. Following the post-trigger sampling period, the stored analog samples are sequentially read out and converted to digital sample values. The digital sample values may be analyzed in a digital processor to further confirm the validity of the returned LIDAR pulse, to determine a time of arrival of the LIDAR pulse, and to calculate a distance to the target object. Some versions include multiple circular buffers and capture clocks, enabling the capture of samples from multiple return pulses. | 04-30-2015 |

| 20090066931 | Distance measurement method, medium, and apparatus for measuring distance between the distance measurement apparatus and target object - A distance measurement method, medium, and apparatus for measuring a distance between the distance measurement apparatus and a target object are provided. The distance measurement method comprises counting pulses of a clock pulse signal having a low frequency during a period from when an optical pulse signal is applied to a target object by a distance measurement apparatus to when the optical pulse signal reflected from the target object is received by the distance measurement apparatus, counting pulses of the clock pulse signal during a period from when the optical pulse signal is received by the distance measurement apparatus to when the received optical pulse signal and the clock pulse signal correspond to each other, and calculating a distance between the distance measurement apparatus and the target object using the counting results. Accordingly, the distance can be measured with high accuracy using the optical pulse signal and the clock pulse signal, thereby reducing costs and power consumption. | 03-12-2009 |
