Abstract: Movement of an autonomously motile device may be controlled by a user device. The user device may display image data captured by a camera of the autonomously motile device; a user may provide input, such as a touch gesture on a display screen, indicating a command for the autonomously motile device to move to a location indicated by the input. The autonomously motile device determines a coordinate of the input and a time of the touch input; the autonomously motile device then determines a direction and distance of a corresponding movement.

Abstract: To reduce the reliance on software for complex computations used in machine sensory perception, a sensory perception accelerator may include a neural network accelerator a linear algebra accelerator. The neural network accelerator may include systolic arrays to perform neural network computation circuits concurrently on image data and audio data. The linear algebra accelerator may include matrix computation circuits operable to perform matrix operations on image data and motion data.

Abstract: An autonomous mobile device (AMD) with various sensors may move through a physical space without human intervention. The AMD may communicate with other devices, such as a user's smartphone or network enabled speaker. Security and privacy for end-to-end communication is provided that involves user interaction with the AMD itself. The sequence of data exchanges and the user interaction with the AMD helps assure the association is authorized and provide for a secure communication channel. Attempts to tamper with the association process, including a man in the middle exploit, are readily detectable and result in a failure. Once detected, actions may be taken, such as notifying the user.

Abstract: A mobile computing device comprises a relative position determination circuit, a position determination circuit, and a processing circuit. The relative position determination circuit is configured to provide relative position data from a first position of the mobile computing device to a second position of the mobile computing device. The position determination circuit is configured to provide position data representing the second geographic position of the mobile computing device. The processing circuit is configured to generate position data for the first position based on the relative position data and the position data.

Abstract: Management of file system changes among multiple instances is provided. Changes to file systems include addition, modification, and removal of files. A modification sentry monitors file system operations taking place on the source file system. When a file is modified on the source file system, the modification sentry makes a corresponding entry in the repository. If a file is added, the file name and file contents are stored in the repository. If a file is modified, the file name, modification, and additionally the entire file are stored in the repository. If a file is removed, only the name of the file is stored in the repository. Logic is also provided for propagating modifications to special-type files. To propagate the modifications to target file systems, a file system update engine of packages a vector derived from the repository for application to other file systems.
