  • Patent number: 11912304
    Abstract: An autonomous mobile device (AMD) moves in a physical space and uses a dock located at a first pose. Sometimes a user may move the dock. To determine whether the dock has moved, the AMD compares first pose data that was previously obtained while at the dock in the first pose to second pose data, such as after a restart or after leaving the dock. If a difference between the first pose and the second pose is greater than a threshold, the dock has moved. The pose data may be determined using a simultaneous localization and mapping (SLAM) algorithm to process images from cameras on the AMD. Transform data that relates coordinates of the second pose to coordinates of the first pose may be determined. If the dock is used as an origin for a map of the physical space, the transform data may be used to update the map.

  • Patent number: 10999636
    Abstract: Systems, methods, and computer-readable media are disclosed for voice-based content searching. The systems, methods, and computer-readable media described herein may improve user experiences by providing voice-based content searching using mobile devices. In an example method described herein, a computer system may receive a voice search initiation signal from a mobile device over a WiFi protocol connection or a Bluetooth protocol connection. The computer system may monitor a WiFi receiver and a Bluetooth receiver of the computer system for first voice data. The computer system may determine that the first voice data is being received at the WiFi receiver. The computer system may determine that second voice data is received at the Bluetooth receiver while the first voice data is being received at the WiFi receiver, and discard the second voice data.
