Abstract: Techniques for locating wireless channels usable for transmitting media signals from personal media players that are adequately separated from wireless channels used for other purposes. One technique involves identifying a target channel and at least two additional channels within a certain proximity of the target channel, and evaluating a channel usability algorithm based on characteristics, such as the received signal strengths, of the target channel and the received signal strengths of each of the proximate channels. Based on evaluation of the algorithm, the target channel is deemed either usable or not usable to transmit the media signal. The most desirable available target channel(s) in a particular group or sub-group of wireless channels may also be identified.

Abstract: A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.
