    Abstract: Techniques to determine a distance associated with a surface using time-of-flight (ToF) of pulses of light occurring at a predetermined frequency. A ToF camera may include a light emitter that emits light according to one or more phase delays relative to the configured of a first storage device of multiple storage devices of the ToF camera to receive light, convert to current, and store a charge corresponding to current. For instance, a light emitter may emit pulses at a 0° phase delay (i.e., simultaneously with the opening of the first storage device), a 90° phase delay, a 180° phase delay, and a 270° phase delay. Light captured and stored as energy in the storage devices may be then be analyzed to estimate a distance to a surface of an object in an environment. After estimating a distance between the ToF camera and a surface, the ToF camera may optimize its phase delay to reduce the error associated with a subsequent distance measurement.

    Abstract: A portable audio input/output device may include one or more openings that extend through a cover of the device and allow acoustic signals outside a housing of the device to reach a microphone disposed within the housing. The opening(s) may be illuminated by a light guide disposed within the housing, which scatters light emitted from lights disposed within the housing. In some instances, a hole may pass through a printed circuit board to allow acoustic signals to be received by the microphone disposed below the printed circuit board. An input/output (I/O) interface module with multiple buttons and inputs may be installed in the hole. The multiple buttons and I/O ports of the I/O interface module may be aligned along an axis vertical relative to the housing and centered with respect to each other.

    Abstract: Devices that include light assemblies for providing visual feedback to users that operate the electronic devices. In some instances, the devices comprise voice-controlled devices and, therefore, include one or more microphones for receiving audible commands from the users. After receiving a command, for instance, one such voice-controlled device may cause a corresponding light assembly of the device to illuminate in some predefined manner. This illumination may indicate to the user that device has received the command. In other instances, the devices may illuminate the lighting assembly for an array of other purposes. For instance, one such device may illuminate the corresponding light assembly when powering on or off, playing music, outputting information to a user (e.g., via a speaker or display), or the like.

    Abstract translation: 包括用于向操作电子设备的用户提供视觉反馈的灯组件的设备。 在一些情况下，设备包括语音控制设备，因此包括用于从用户接收可听命令的一个或多个麦克风。 例如，在接收到命令之后，一个这样的语音控制设备可以使得设备的相应的灯组件以某种预定义的方式照亮。 该照明可以向用户指示设备已经接收到该命令。 在其他情况下，装置可照亮照明组件以用于其它目的的阵列。 例如，一个这样的设备可以在打开或关闭电源，播放音乐，向用户输出信息（例如通过扬声器或显示器）等时照亮对应的灯组件。
