  • Patent number: 11836940
    Abstract: A computing device includes: a three-dimensional (3D) sensor configured to capture point cloud data from a field of view (FOV); an auxiliary sensor configured to capture reference depth measurements corresponding to a surface within the FOV; a controller connected with the 3D sensor and the auxiliary sensor, the controller configured to: detect a reference depth capture condition; when the reference depth capture condition satisfies a quality criterion, control the auxiliary sensor to capture a reference depth corresponding to the surface within the FOV; and initiate, based on the captured reference depth, generation of corrective data for use at the 3D sensor to capture the point cloud data.

  • Patent number: 10667219
    Abstract: A method for power management of a mobile device includes detecting whether a removable power source has been removed from the mobile device. In response to detecting that the power source has been removed, entering a hot swap mode for a first time period by deactivating a first component of the mobile device and maintaining, via a backup power source in the mobile device, a powered state of a second component of the mobile device and an application state of the mobile device. The method further includes, after the first time period, entering a suspend mode for a second time period by deactivating the second component and continuing to maintain the application state of the mobile device for the second time period.

  • Patent number: 10552750
    Abstract: Described is a multiple-camera system and process for disambiguating between multiple users and identifying which of the multiple users performed an event. For example, when an event is detected, user patterns near the location of the event are determined, along with touch points at the location of the event. User pattern orientation and/or arm trajectories between the event location and the user patterns may be determined and processed to disambiguate between multiple users and determine which user pattern is involved in the event.

  • Patent number: 10060239
    Abstract: A method for stimulating heavy oil recovery from CHOPS wells at or nearing the end of productive life but not experiencing water-out, wherein produced water is heated to below boiling point and injected back downhole to reduce heavy oil viscosity in the near-wellbore region and surrounding the wormhole network, enabling existing reservoir pressure to drive the reduced-viscosity heavy oil toward the well for production to surface. The injection-soak-production cycle can be repeated as desired so long as adequate reservoir pressure exists.

  • Patent number: 9134780
    Abstract: A computer includes a communication unit for obtaining usage data and/or run-time data associated with the computer, at least one component communicatively coupled to the computer, and/or a vehicle on which the computer is mounted and from which the computer is configured to receive power. The computer further includes a processor configured to: extrapolate out of the usage data and run-time data patterns associated with activities implemented by the computer and/or the at least one component and power states of the vehicle and create and store a profile of patterns; receive an indication that the vehicle has been toggled to one of an ON power state and an OFF power state; identify a pattern associated with the power state of the vehicle; and adapt a power state of the computer and/or the at least one component responsive to the indication and the pattern.
