20090278030 | METHOD OF LOCATING AN OBJECT IN 3-D - Methods and devices for calculating the position of a movable device are disclosed. The device may include multiple optical detectors (ODs) and the movable device may include light sources. Optics may be above the ODs. A controller may calculate the position of the light source based on data from the ODs and properties of the optics. The device may be a game console, and the light source may be a game controller. The roles of the OD and light sources may be interchanged. The rotation of the movable device may be determined using multiple light sources and/or multiple ODs on the movable device. The movable device may calculate its position and transmit it to a console. The light sources may be modulated by time or frequency to distinguish between the light sources. There may be two or more movable devices. There may be two or more consoles. | 11-12-2009 |
20110079703 | OBJECT TRACKING SYSTEM - An optical tracking system comprises an array of point source emitters that output respective optical emissions, and a plurality of angle of arrival sensors. Each sensor comprises one or more optical elements and a focal plane array (FPA), with the optical elements arranged to resolve the optical emissions into one or more linear patterns on the FPA. A processing system in communication with the sensors establishes the orientation and position of each of the optical emitters using the linear patterns. A headgear tracking system employs point source emitters on a piece of headgear, with front and rear arrays of angle of arrival sensors located in an aircraft cockpit; a processing system in communication with the sensor arrays establishes an orientation and position for each of the optical emitters on the headgear. | 04-07-2011 |
20120175496 | APPARATUS AND METHOD FOR NAVIGATION - An apparatus and system for use in determining location of a celestial body are presented. The apparatus comprises: a polarizer comprising an array of polarized light filter cells and a light sensor array. The array of polarized light filter cells comprises at least a first polarization direction and a second polarization direction different from said first polarization direction. And the polarizer thereby produces polarized light of at least first and second different polarizations. The light sensor array is configured to receive the polarized light from the polarizer and produce data indicative of a pattern of at least one of light polarization intensity and direction. The pattern is indicative of at least one of azimuth and elevation of the celestial body to be located. | 07-12-2012 |
20120326007 | OBJECT DETECTING DEVICE AND INFORMATION ACQUIRING DEVICE - An information acquiring device has a light source which emits light of a predetermined wavelength band; a light receiving element which receives reflected light reflected on the target area for outputting a signal; an information acquiring section which searches a corresponding area corresponding to the segment area from an actual measurement pattern of the light received by the light receiving element; and a spreading detecting section which detects a change in a degree of spreading of a light receiving area of the actual measurement pattern. The information acquiring section performs a searching operation of the corresponding area along a searching line in parallel to an alignment direction in which the light source and the light receiving element are aligned, and displaces the searching line with respect to each segment area in a direction perpendicular to the alignment direction in accordance with the change in the degree of spreading. | 12-27-2012 |
20130264463 | OPTICAL SURVEILLANCE SYSTEM FOR A SPACE SURVEY SYSTEM FOR MONITORING NEAR-EARTH SPACE - An optical system for surveillance systems for space surveillance systems includes at least one telescope with a field greater than or equal to 5° mounted on a mobile mount along two axes, and coupled with an image sensor, whose sensitivity is designed for an integration time of the order of magnitude of a hundred milliseconds. | 10-10-2013 |
20150301160 | LASER SCANNER - A laser scanner measures a surface of spaces and/or objects and produces a point cloud representing the surface. The laser scanner includes a laser source for producing laser light, a detector for receiving the laser light, and a platform that pivots relative to a stationary base of the laser scanner. The laser light is directed to a particular point on the surface through an outlet point. Laser light scattered at the particular point is received through an inlet point on the platform. A distance to the particular point is determined using laser light scattered and received by the detector. A direction to the particular point is detected using, for example, one or more sensors for determining a pivot position of the platform relative to the base. A parallel kinematic drive pivots the platform relative to the base to scan the laser beam over points of the surface. | 10-22-2015 |
