摘要： A method for constructing a 3D representation of a subject comprises capturing, with a camera, a 2D image of the subject. The method further comprises scanning a modulated illumination beam over the subject to illuminate, one at a time, a plurality of target regions of the subject, and measuring a modulation aspect of light from the illumination beam reflected from each of the target regions. A moving-mirror beam scanner is used to scan the illumination beam, and a photodetector is used to measure the modulation aspect. The method further comprises computing a depth aspect based on the modulation aspect measured for each of the target regions, and associating the depth aspect with a corresponding pixel of the 2D image.

摘要： Techniques are provided for determining distance to an object in a depth camera's field of view. The techniques may include raster scanning light over the object and detecting reflected light from the object. One or more distances to the object may be determined based on the reflected image. A 3D mapping of the object may be generated. The distance(s) to the object may be determined based on times-of-flight between transmitting the light from a light source in the camera to receiving the reflected image from the object. Raster scanning the light may include raster scanning a pattern into the field of view. Determining the distance(s) to the object may include determining spatial differences between a reflected image of the pattern that is received at the camera and a reference pattern.

摘要： An object placed on an interactive display surface is detected and its position and orientation are determined in response to IR light that is reflected from an encoded marking on the object. Upon detecting the object on an interactive display surface, a software program produces a virtual entity or image visible through the object to perform a predefined function. For example, the object may appear to magnify text visible through the object, or to translate a word or phrase from one language to another, so that the translated word or phrase is visible through the object. When the object is moved, the virtual entity or image that is visible through the object may move with it, or can control the function being performed. A plurality of such objects can each display a portion of an image, and when correctly positioned, together will display the entire image, like a jigsaw puzzle.

摘要： A system and method are disclosed for synthesizing information received from multiple audio and visual sources focused on a single scene. The system may determine the positions of capture devices based on a common set of cues identified in the image data of the capture devices. As a scene may often have users and objects moving into and out of the scene, data from the multiple capture devices may be time synchronized to ensure that data from the audio and visual sources are providing data of the same scene at the same time. Audio and/or visual data from the multiple sources may be reconciled and assimilated together to improve an ability of the system to interpret audio and/or visual aspects from the scene.

摘要： Various embodiments are disclosed for a thermal management system and related method for selectively thermally isolating and thermally connecting a target component. One embodiment of a system includes a first component having a first surface proximate to a target component, and an electromagnet between the first surface and the target component. A second component is spaced apart from the first component to form a gap that serves as a thermal boundary between the first component and the second component. A carrier fluid disposed within the gap includes multiple thermally conductive, ferrous particles. The carrier fluid is configured to align at least a portion of the thermally conductive, ferrous particles when the electromagnet generates a magnetic field that attracts the particles, and to displace at least a portion of the particles when the electromagnet generates a magnetic field that repels the particles.

摘要： An interactive display system configured for detecting an object or user input provided with an object. The system includes a display surface on which graphic images are displayed, one or more scanning light sources configured for scanning the interactive display surface, and a light detector configured for detecting light reflected from an object that is adjacent to or in contact with the interactive display surface. A computing system storing machine instructions is in communication with the scanning light source and the light detector. When executed, the machine instructions cause the computing system to illuminate the interactive display surface with the scanning light source, to detect light with the light detector that is reflected from an object after illumination with the light source, and to generate an output signal based on the detected light that has been reflected from an object on or adjacent to the interactive display surface.
