Patent number: 9143902Abstract: A method and apparatus for creating a communication group for a given type of communication using a mobile station for initiating communication sessions of the given type among mobile stations are disclosed. A group definition for determining members of the new communication group is composed from one or more contacts from the electronic address book such as by selecting from the address book using the mobile station. The group definition may include logical operators to define the combination of contacts. A name may be specified for the new group. The assembly of the list of members may be performed by the mobile station, a communication network server for maintaining groups (e.g. a Group and List Management Server (GLMS)) or an email server.Type: GrantFiled: October 23, 2014Date of Patent: September 22, 2015Assignee: BlackBerry LimitedInventors: Runbo Fu, Wen Zhao, Xin Jin

Patent number: 9071703Abstract: An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.Type: GrantFiled: May 7, 2014Date of Patent: June 30, 2015Assignee: BlackBerry LimitedInventors: Wen Zhao, Runbo Fu, Xin Jin, Pokin Yeung, Karen A.

Patent number: 8589098Abstract: An electrical device is powered by a battery. The device includes transition phase determining circuitry operatively connected to the battery to determine that the battery has entered a transition phase based on the occurrence of a change in direction of current flowing through the battery. Battery capacity determining circuitry is operatively connected to the transition phase determining circuitry and configured to determine, in response the transition phase determining circuitry determining that the battery is in the transition phase, a capacity of the battery based on a transition phase battery capacity model of capacity-vs.-voltage. The transition phase determining circuitry is further configured to determine an end of the transition phase based on the transition phase battery capacity model and a non-transition battery capacity model of capacity-vs.-voltage yielding the same capacity value for a given measured voltage of the battery.Type: GrantFiled: August 20, 2012Date of Patent: November 19, 2013Assignee: BlackBerry LimitedInventors: Farhad Ahmed, Runbo Fu
