Patent number: 7164676Abstract: Methods and apparatus are disclosed for a combined bulk and transactional database synchronization scheme. A dynamically changing primary database is initially duplicated to a secondary database using bulk and transactional updates. Then, the secondary database is maintained in synchronization with the primary database using transactional updates. In one implementation, the primary database is divided into synchronization groups. Initially, all the groups are marked as requiring bulk synchronization. Systematically, entries from a group are combined into a bulk update message and relayed to a secondary device or component to bulk update the secondary database. When a new update to the primary database is made, if the group to which it belongs is in the process of, or still requires bulk updating, this new update will be propagated to the secondary database in due course with a subsequent bulk update. Otherwise, the new update is placed in transactional update message.Type: GrantFiled: March 21, 2001Date of Patent: January 16, 2007Assignee: Cisco Technology, Inc.Inventor: Anindya Chakraborty

Patent number: 7133707Abstract: A dial keypad is provided for use with a mobile device having a keyboard. The keypad has a push-through, hinge-spring design that activates only one of two keyboard keys underlying a dial key and allows backlighting transmissivity. A translucent material can be used to allow the keyboard key backlighting to be coupled through to a top dial key. The keypad creates an aesthetically balanced dial keypad arrangement over a QWERTY keyboard. A preferable mechanical implementation allows backlighting and has an offset contact and spring design to activate one of the two underlying keys. This activation simplifies the software implementation for executing the dial number since the signal is coming from one address rather than having to make a determination of whether it is coming from one or two addresses. Moreover, the resulting dial key press has a standard single click feel.Type: GrantFiled: July 13, 2004Date of Patent: November 7, 2006Assignee: Research In Motion LimitedInventors: Roman Peter Rak, Jason Griffin, Steven Fyke, Paul Robert Chyc
