Patent number: 9474027Abstract: A method of internally heating a power supply of an electronic device in reduced temperatures is provided. The method comprises positioning an antenna of the electronic device proximate to the power supply and receiving a “temperature” signal that is a function of a temperature of the power supply. When it is determined that the temperature is within a reduced operating-temperature range, the temperature is elevated and the equivalent series resistance (ESR) of the power supply is correspondingly reduced by actively sending current through the antenna. The “current sending” operation is reduced when the temperature of the portable electronic device is outside the reduced operating-temperature range.Type: GrantFiled: November 25, 2013Date of Patent: October 18, 2016Assignee: BlackBerry LimitedInventors: Philip James Prociw, Chee-Ming Jimmy Wu, Yu William Feng

Patent number: 9146282Abstract: Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.Type: GrantFiled: December 2, 2010Date of Patent: September 29, 2015Assignee: BlackBerry LimitedInventors: Chee-Ming Jimmy Wu, Lyall Kenneth Winger, Christopher Simon Book

Publication number: 20120194130Abstract: Systems and methods to detect a failure of a subset of component power packs within a multiple component rechargeable power pack. At least one parameter of a charging current that is provided for a time duration to a rechargeable power pack is determined. A measured capacity change quantity for the rechargeable power pack during the time duration is estimated. The measured capacity change quantity is compared, after the time duration, to an expected capacity change quantity that is based upon the at least one parameter. A determination is made that at least one component power pack within the rechargeable power pack has failed based on a difference between the measured capacity change quantity and the expected capacity change quantity. A charging current parameter is modified in response to the determining that the at least one component power pack has failed.Type: ApplicationFiled: September 20, 2011Publication date: August 2, 2012Applicant: Research In Motion LimitedInventors: Joseph PATINO, Ryan Alexander GERIS, Jonathan Quinn BRUBACHER, Chee-Ming Jimmy WU
