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: 10552750Abstract: 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.Type: GrantFiled: December 23, 2014Date of Patent: February 4, 2020Assignee: Amazon Technologies, Inc.Inventors: Sudarshan Narasimha Raghavan, Emilio Ian Maldonado, David Allen Smith, Min Xu, Nishitkumar Ashokkumar Desai, Daniel Bibireata, Kevin Kar Wai Lai, Pahal Kamlesh Dalal

Patent number: 10060239Abstract: 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.Type: GrantFiled: December 15, 2016Date of Patent: August 28, 2018Assignee: Husky Oil Operations LimitedInventor: Kevin Kar Wan To
