Abstract: Technologies related to task management across low-power wireless communications are generally described. In some examples, proximal devices in range of low-power wireless communications may cooperate to allow one or more of the proximal devices to suspend task operations, while one or more of the proximal devices manage the task operations. The task operations may be associated with an energy consumption that exceeds an energy consumption associated with the low-power wireless communications, allowing the proximal devices that suspend task operations to reduce their overall energy consumption.

Abstract: Technologies are generally described for measuring hair moisture using a hair moisture measuring device including a vibrator, a sound wave detector, a heater, and/or a processor. The vibrator may generate and propagate first sound waves through a strand of hair, which may be detected by the sound wave detector. The processor may then measure a first time-delay between the first sound waves and the first driving signals. After heating the hair by the heater, the vibrator may generate and propagate second sound waves through the strand of hair, which may be detected by the sound wave detector. The processor may measure a second time-delay between the second sound waves and the second driving signals, and also measure an amount of the moisture by calculating a time-delay difference between the first time-delay and the second time-delay.

Abstract: Technologies are generally described for coordination of structured light-based image detectors. In some examples, one or more structured light sources may be configured to project sets of points onto the scene. The sets of points may be arranged into disjoint sets of geometrical shapes such as lines, where each geometrical shape includes a subset of the points projected by an illumination source. A relative position and or a color of the points in each geometrical shape may encode an identification code with which each illumination source may be identified. Thus, even when the point clouds projected by each of the illumination sources overlap, the geometrical shapes may still be detected, and thereby a corresponding illumination source may be identified. A depth map may then be estimated based on stereo vision principles or depth-from-focus principles by one or more image detectors.

The processor may determine a difference between the first and the second activity simulation and modify the augmented reality instructions to generate a modified virtual object in response to the determination of the difference.
