| 20090287987 | NON-DESTRUCTIVE MEDIA PRESENTATION DERIVATIVES - The claimed subject matter relates to various architectures that can, inter alia, facilitate creation of a synch file as well as facilitate interpretation of the synch file. Both creation and interpretation can be accomplished in conjunction with an original media asset. The synch file can include transformation commands that can operate on a presentation of the asset rather than upon the asset itself. Accordingly, what is actually perceived by a content consumer during a presentation of the asset need not be exactly what the asset creator fixed in a tangible medium. Rather, the content consumer can observe a derivative media presentation based upon interpretation of the synch file. | 11-19-2009 |
| 20100277411 | USER TRACKING FEEDBACK - Technology is presented for providing feedback to a user on an ability of an executing application to track user action for control of the executing application on a computer system. A capture system detects a user in a capture area. Factors in the capture area and the user's actions can adversely affect the ability of the application to determine if a user movement is a gesture which is a control or instruction to the application. One example of such factors is a user being out of the field of view of the capture system. Some other factor examples include lighting conditions and obstructions in the capture area. Responsive to a user tracking criteria not being satisfied, feedback is output to the user. In some embodiments, the feedback is provided within the context of an executing application. | 11-04-2010 |
| 20110062309 | OPTICAL FAULT MONITORING - Various embodiments related to monitoring for optical faults in an optical system are disclosed. For example, one disclosed embodiment provides, in an optical system comprising a light source, a light outlet, and an optical element disposed between the light source and the light outlet, a method of monitoring for optical system faults. The method includes detecting, via a light sensor directed toward an interface surface of the optical element closest to the light source, an intensity of light traveling from the interface surface of the optical element to the light sensor, and comparing an intensity of light detected to one or more threshold intensity values. The method further includes identifying an optical system fault condition based on comparing the intensity of light detected to one or more threshold values, and modifying operation of the optical system. | 03-17-2011 |
| 20110064402 | SEPARATION OF ELECTRICAL AND OPTICAL COMPONENTS - Embodiments related to establishing and maintaining precision alignment in an optical system are disclosed. For example, one disclosed embodiment provides an optical device comprising an outer casing and a rigid optical support disposed within an interior of the outer casing and to which a plurality of optical components are mounted. The embodiment further comprises a printed circuit board spatially separated from the optical support and the plurality of optical components, wherein one or more electrical components are mounted to the printed circuit board. The embodiment also comprises one or more electrical conductors electrically connecting the one or more electrical components to the one or more optical components. | 03-17-2011 |
| 20110069221 | ALIGNMENT OF LENS AND IMAGE SENSOR - Embodiments related to the alignment of a lens with an image sensor in an optical device are disclosed. For example, one disclosed embodiment comprises an optical device including a printed circuit board, and an image sensor package mounted on the printed circuit board, wherein the image sensor package includes an image sensor. The optical system further comprises a lens holder including a lens, and one or more alignment features arranged on the lens holder. The one or more alignment features are configured to contact the image sensor package to mechanically align the lens holder with the image sensor package. | 03-24-2011 |
| 20110228251 | RASTER SCANNING FOR DEPTH DETECTION - 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. | 09-22-2011 |
| 20110243167 | Temperature Measurement And Control For Laser And Light-Emitting Diodes - The existing diodes in an LED or laser diode package are used to measure the junction temperature of the LED or laser diode. The light or laser emissions of a diode are switched off by removing the operational drive current applied to the diode package. A reference current, which can be lower the operational drive current, is applied to the diode package. The resulting forward voltage of the diode is measured using a voltage measurement circuit. Using the inherent current-voltage-temperature relationship of the diode, the actual junction temperature of the diode can be determined. The resulting forward voltage can be used in a feedback loop to provide temperature regulation of the diode package, with or without determining the actual junction temperature. The measured forward voltage of a photodiode or the emissions diode in a diode package can be used to determine the junction temperature of the emissions diode. | 10-06-2011 |
| 20110279648 | SCANNED-BEAM DEPTH MAPPING TO 2D IMAGE - 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. | 11-17-2011 |
