Abstract: In an embodiment, a device may include an attention detection service. The attention detection service may monitor various peripheral devices in the device for indications that a user is paying attention to the device. Various clients may register for notification of attention detection and attention lost (attention no longer detected) events, or may poll the service for the events. If a user is not paying attention to the device, it may be possible to take various actions to permit reduced energy consumption.

Abstract: A space-bred seawater Spirulina H11 strain. The strain exhibits high growth rate, capacity of simultaneously accumulating high contents of phycocyanin, Spirulina polysaccharides and ?-carotene, and excellent adaptability to outdoor environment, thus can be used to produce high-quality Spirulina powders, phycocyanin, Spirulina polysaccharides, and ?-carotene-rich Spirulina oil.

Abstract: Methods and systems are provided herein for measuring 3D apparatus (e.g., manual tool or tool accessory) orientation. Example implementations use an auto-nulling algorithm that incorporates a quaternion-based unscented Kalman filter. Example implementations use a miniature inertial measurement unit endowed with a tri-axis gyro and a tri-axis accelerometer. The auto-nulling algorithm serves as an in-line calibration procedure to compensate for the gyro drift, which has been verified to significantly improve the estimation accuracy in three-dimensions, especially in the heading estimation.

Abstract: Systems, methods, computer readable media and articles of manufacture consistent with innovations herein are directed to gesture based user interaction, user interface and/or other features. According to one illustrative implementation, for example, an illustrative operating system may comprise an input program using images from one or more cameras to analyze and interpret user gestures, may (in some implementations) involve an operating system based on Linux kernel with access to local disks and files, and/or may include or involve a graphical user interface outputting the cursor corresponding to user gestures and providing a uniquely designed interaction between the gestures and content. Additional aspects for interacting with other/multiple devices are also disclosed.
