摘要： An audio processing system configured to generate, based at least in part on captured sound, an audio signal that includes a speech component corresponding to a user's speech utterance and an audio component corresponding to audio output of another device is described herein. The audio processing system is also configured to receive a reference signal that corresponds to the audio output of the other device. The reference signal may be received as ultrasonic audio output of the other device or from a remote server. The audio processing device then processes the generated audio signal to remove at least a part of the generated audio signal that corresponds to the reference signal.

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： Techniques are described for compensating for distortion effects caused by projecting images to a surface that is non-perpendicular to a raster-scanning laser projector. Pixel size is modulated such that smaller pixels are projected to farther portions of the surface, and larger pixels are projected to nearer portions. Pixels within a raster scan line may have their lengths modulated through variation of a frequency of light source that generates the pixels, or through adjustment of a scan speed along the line. Pixel heights may be adjusted by modulating the distance between scan lines. Scan speed and distance between scan lines may be modified by controlling micromirrors incorporated into the laser projector for directing the light projection.

摘要： Techniques are described for reducing safety-relevant emission of a laser projection system. A multi-facet optical element is positioned in the path of a raster-scanning laser beam. Each facet of the optical element is angled to redirect a projected pixel to a different pixel position. Collectively, the facets are configured to convert the projected raster scan into a non-raster scan in which physically proximate pixels are illuminated temporally non-proximate times.

摘要： Techniques for providing audio services to multiple devices are described. For instance, connections between a hands-free unit and multiple wireless devices are established. The connections are themselves used to establish active communication channels, such as active audio communication channels, between the hands-free unit and the wireless devices, such as during a phone call. Upon establishment of an active communication channel with one of the wireless devices, the connections to the other wireless devices are disconnected—and/or additional connections refused—for the duration of the active communication channel. Furthermore, a routing module in various embodiments permits multiple hands-free units to route active communication channels to each other depending on user location.

摘要： A projection and camera system projects content onto a passive, multi-surface projection screen. When a first surface of the screen is oriented to receive the projected images, the system detects this first surface and projects content associated with that surface of the screen. When a second surface is oriented to receive the projected images, the system detects this change from the first surface to the second surface and projects different content associated with the second surface. In this manner, to switch between different content or different applications, the user merely needs to turn the screen over.
