摘要： Technology for detecting a change in a configuration position of one or more elements in an illumination system is described. A light source generates an illumination signal, and an element of the system directs a portion of the light of the signal back to a light detector. In one example, the portion of light is reflected back to the light detector. By monitoring an output signal of the light detector based on the directed light, control circuitry can detect that a position of an element of the system has changed. In one example, an off-the-shelf integrated circuit laser diode package including a monitor photodiode can be used with a reflective element. In one example, the reflective element is a tilted optical element. Changes can be detected in the configuration of one or more optical elements of the illumination system which are outside the laser diode package.

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： 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.

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.
