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: Displays are described. One display having a reflective display, a light guide, and a light guide cover. The light guide is disposed on a top side of the reflective display. The light guide cover is disposed on the light guide. The light guide cover includes: a cover glass disposed above the light guide; an opaque layer, disposed above the cover glass and around an edge of the reflective display that absorbs light reflected off the reflective display; and a white ink layer disposed above the opaque layer.

Abstract: An autonomous mobile device (AMD) may perform tasks within a physical space. The AMD may move over ramps, bumps, or navigate around obstacles. The AMD may have an inertial measurement unit (IMU) and distance sensors. The IMU provides tilt information indicative of the AMD being on a flat surface or a ramp. The distance sensors provide information on distances between the AMD and surrounding obstacles. Using IMU measurements, the AMD determines a first speed limit that is safe given the tilt of the AMD. Using the distance sensors, the AMD determines a second speed limit that is safe given a distance to an obstacle. The AMD determines a maximum speed based on the first and second speed limits. Based on the maximum speed, the AMD determines whether to adjust a current speed and by how much.

Abstract: Devices and techniques are generally described for estimation of ambient light levels. In various examples, an image sensor may capture a frame of image data. In some examples, an ambient light value of the frame may be determined. In some examples, a first region of the frame corresponding to a first physical characteristic and a second region of the frame corresponding to a second physical characteristic may be determined. In various examples, a first reflection coefficient associated with the first physical characteristic and a second reflection coefficient associated with the second physical characteristic may be determined. In some examples, an IR correction value may be determined for the frame of image data based at least in part on the first reflection coefficient and the second reflection coefficient. An estimated ambient light value may be determined based at least in part on the IR correction value and the ambient light value.
