    摘要： In some embodiments, a distance between the at least one light sensor and the surface may be calculated using a ratio representative of the phase difference using time-of-flight of light. The distance may be within a distance range defined by a distance of light travel during a modulation period of the predetermined frequency. The distance may be based on the ratio defined by an amount of energy stored from captured light during a first time interval and a second time interval, and a comparison of an amount of light stored from captured light during at least a third time interval. The first, second, and third time intervals are different, but may overlap in some instances. In some embodiments, the amount of ambient light may be identified and subtracted from the inputs of the ratio. A switch may be used to prevent oversaturation of a storage element storing the stored energy.

    摘要翻译： 在一些实施例中，可以使用代表光的飞行时间的相位差的比率来计算至少一个光传感器与表面之间的距离。 距离可以在由预定频率的调制周期内的光行进距离限定的距离范围内。 该距离可以基于由在第一时间间隔和第二时间间隔期间从捕获光存储的能量的量定义的比率，以及在至少第三时间间隔期间从捕获的光存储的光量的比较。 第一，第二和第三时间间隔是不同的，但在某些情况下可能重叠。 在一些实施例中，环境光的量可以被识别并从该比率的输入中减去。 可以使用开关来防止存储存储的能量的存储元件的过饱和。

    摘要： A computing device may operate in various modes, which may include a full operational mode and a reduced operational mode. When operating in the reduced operational mode, the computing device may reduce power, reduce radiation output, and/or power off various components to achieve operation in accordance with an operational policy. While operating in the reduced operational mode, the computing device may restrict user access to or adjustment of the impacted components thereby preventing the user from restoring the computing device to the full operational mode, at least temporarily. In some aspects, the device may initiate or terminate the reduced operational mode in response to a signal from a beacon, parameters from a monitored environment, or in response to user commands. In various aspects, the device may provide messaging to inform the user about the modes of operation.

    摘要翻译： 计算设备可以以各种模式操作，其可以包括完全操作模式和降低的操作模式。 当以降低的操作模式操作时，计算设备可以根据操作策略降低功率，减少辐射输出和/或关闭各种组件以实现操作。 当以减小的操作模式操作时，计算设备可以限制用户对受影响的组件的访问或调整，从而防止用户至少暂时将计算设备恢复到完全操作模式。 在一些方面，设备可以响应于来自信标的信号，来自被监控环境的参数或响应于用户命令来启动或终止缩减的操作模式。 在各个方面，设备可以提供消息传递以通知用户操作模式。

    摘要： Described are systems and methods for content-adaptive presentation of content. A presentation profile for use in presentation of content is determined based at least in part on one or more determination characteristics. The determination characteristics may include metadata descriptive of the content, such as genre, style, artist, and so forth. The presentation profile may include equalizer settings, overall amplitude or volume, speaker configuration, and so forth.

    摘要： A user can provide input to a computing device through various combinations of speech, movement, and/or gestures. A computing device can analyze captured audio data and analyze that data to determine any speech information in the audio data. The computing device can simultaneously capture image or video information which can be used to assist in analyzing the audio information. For example, image information is utilized by the device to determine when someone is speaking, and the movement of the person's lips can be analyzed to assist in determining the words that were spoken. Any gestures or other motions can assist in the determination as well. By combining various types of data to determine user input, the accuracy of a process such as speech recognition can be improved, and the need for lengthy application training processes can be avoided.
