  • Patent number: 10567388
    Abstract: A policy/resource decommissioning service determines whether a resource has been inactive for a period of time greater than at least one period of time threshold for decommissioning. If the resource has been inactive greater than a first period of time threshold, the service disables the resource such that requests to access the resource are denied. If the resource has been inactive for a period of time greater than a second threshold, longer than the first period of time threshold, the service archives the resource. The service deletes the resource if the inactivity period of the resource is greater than a third period of time threshold, where the third period of time threshold is longer than the first and the second period of time thresholds.

  • Patent number: 10496888
    Abstract: A process for selectively activating a guardian camera in response to detecting a distracted user includes first identifying an available camera external to a mobile computing device (MCD) having a field of view that incorporates a current location of a user of the MCD. The MCD then detects that a user's attention is substantially focused on a user interface of the MCD, and responsively transmits an instruction to the available camera to transition to a recording state and/or to begin monitoring an area surrounding the user for unexpected movements or objects. In response to the MCD detecting an indication that the available camera has recorded an unexpected movement or object in the area surrounding the user, the MCD takes a responsive action.

  • Patent number: 10425986
    Abstract: Missed voice stream portions are replayed at a late entry subscriber device (SD) in a wireless radio network. The SD joins a voice call on a radio channel via a base station and detects that it is late to the call. The SD continues to receive a remaining portion of the call and plays back the portion of the call. The SD detects an end of the voice call, and (i) transmits a request message including an indication of a first duration of the portion of the call received or (ii) detects a similar message from another SD. The SD then receives an indication of a total duration of the voice call and calculates a third duration as a function of the total duration and the first duration. The SD receives and plays back the missed portion of the call for the third duration.
