Abstract: Provided are systems, methods, and computer-program products for enabling peer-to-peer communications between peripheral devices in a computing system. In various implementations, a host device in the computing system can read an address from a peripheral device included in the computing system. The host device can further configure an emulated peripheral device corresponding to the peripheral device, including writing the address to an emulated register of the emulated peripheral device. The host device can further initiate a virtual machine, including reading the address from the emulated register, initializing a page table for the virtual machine, and initiating a guest operating system. The guest operating system can be operable to use the address to access the physical device.

Abstract: An autonomous mobile device (AMD) follows a user who may move among other people, change orientation, or move in and out view of a camera on the AMD. A predicted location of the user may be determined based on a previous location and previous movement. A proximity value is determined by the distance between a location in physical space of a user and the predicted location. An image from a camera is processed to determine a user depicted in the image and generate a feature vector (FV) of that depiction. A gallery of FVs of the user as viewed from different angles, poses, and so forth is stored. A similarity value is determined between a FV of an unidentified user in an image and the FVs in the gallery. The user may be identified using the proximity value and the similarity value.

Abstract: A power adapter for mobile devices may include an alternating current to direct current (AC/DC) converter. The AC/DC converter may convert electric power from a power source. The power adapter may include a housing enclosing the AC/DC converter. The power adapter may include a power plug extending from the housing along a first axis. The power adapter may include a Universal Serial Bus (USB) plug extending from the housing along the first axis and on an opposite end of the housing from the power plug. The power adapter may include a device charging plug pivotally coupled to the housing.
