摘要： A method includes: obtaining one or more images of a facility containing objects; detecting positions of the objects in the images; determining, from the detected positions, respective locations in a facility coordinate system for each detected object; for each detected object, generating a trajectory based on the determined location; obtaining a set of computing device identifiers and corresponding computing device locations in the facility coordinate system; based on the identifiers and device locations and at least one of (i) the locations of the objects, (ii) the trajectories, or (iii) the image, detecting associations between the objects and the devices; detecting, based on the trajectories, a potential collision between a first detected object and a second detected object; in response to detecting the potential collision, selecting a computing device associated with at least one of the first and second detected objects; and transmitting a collision notification to the selected computing device.

摘要： A method in a client device for updating network configuration parameters, the method comprising: establishing a connection between the client device and an access point connected with a set of other client devices; detecting a connectivity event at the client device; generating a configuration verification request containing current network configuration parameters of the client device; transmitting the configuration verification request for delivery to the set of other client devices; responsive to transmitting the configuration verification request, receiving a configuration verification response from a responding one of the other client devices; and responsive to the configuration verification response indicating non-matching connectivity conditions at the responding client device, initiating a network reconfiguration process at the client device to obtain new network configuration parameters.

摘要： A computing device includes: a wireless communication interface; and a processor configured to: establish a connection with a wireless network; while a network-layer status of the connection is active, monitor attributes of the connection at the wireless communication interface, the attributes including (i) a number of uplink packets transmitted since a most recent downlink packet was received, and (ii) a time period elapsed since the most recent downlink packet was received; determine that the attributes meet recovery criteria indicative of a network-layer interruption in the wireless network; in response to the determination, control the wireless communication interface to initiate a recovery action to resolve the network-layer interruption.

摘要： An example computing device includes: a wireless communications interface configured to connect to a network deployed by one or more access points; a controller for the wireless communications interface, the controller configured to: predict whether a target access point for connecting to the network has an active session with the computing device when the computing device is disconnected from the target access point; when the uncleared session is predicted, send a clearing request to the target access point to clear the active session; and connect to the target access point.
