Patent number: 11836940Abstract: 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.Type: GrantFiled: June 15, 2020Date of Patent: December 5, 2023Assignee: Zebra Technologies CorporationInventors: Patrick B. Tilley, Ronald Zancola, Aleksandar Rajak, Kevin Kar Yin Chan, Peter Randall Daly, Sanjeewa Thimirachandra, Raghavendra Tenkasi Shankar, Alexander Miller, Scott R. Murchison, Eliran Noach

Patent number: 10667219Abstract: 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.Type: GrantFiled: November 25, 2019Date of Patent: May 26, 2020Assignee: Symbol Technologies, LLCInventors: Adrian J. Stagg, Steve Maddigan, Kevin Kar-Yin Chan, James Shoong-Leac Chen

Patent number: 9134780Abstract: 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.Type: GrantFiled: November 11, 2013Date of Patent: September 15, 2015Assignee: Symbol Technologies, LLCInventor: Kevin Kar Yin Chan
