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: 9081973Abstract: A method for restricting, based on predefined user profile information, access to software executing on a computing device of a user. The method comprises the following steps. Input data is intercepted from a user input device. The input data is compared with a list of restrictions in the user profile information to determining if an action associated with the input data is prohibited. The input data is passed to the software for execution only if the action associated with the input data is not prohibited. A method for restricting, based on predefined user profile information, access to notifications generated for a user is also provided.Type: GrantFiled: April 23, 2010Date of Patent: July 14, 2015Assignee: PSION INC.Inventors: Nader Newman, James Shoong-Leac Chen, Timothy Fraser Pearce

Publication number: 20120075107Abstract: A method is provided for representing battery degradation of a rechargeable battery for use with a battery operated device. The method comprises the following steps. At predefined intervals, the battery degradation of the rechargeable battery is determined. An indicator is selected from one of a plurality of predefined indicators based on the determined battery degradation. The selected indicator is displayed on a screen of a computing device for representing the battery degradation. A computing device configured to implement the method is also described.Type: ApplicationFiled: March 24, 2011Publication date: March 29, 2012Inventors: Nader Newman, James Shoong-Leac Chen
