  • Patent number: 8923507
    Abstract: The innovation supports the ability to map alpha characters entered directly into the dialer application of a smartphone. These alpha characters can be entered via a smartphone keyboard (e.g., QWERTY keyboard) and converted to the appropriate digits as mapped to a conventional telephone keypad. The resultant numerical digits can be used to prompt a network call. Additionally, the innovation can be used during an active call to respond to prompts that traditionally require 12-key mappings. This innovation allows a user to both dial a number directly via a smartphone keyboard, and filter contacts by name, in a non-modal manner.

  • Publication number: 20090007143
    Abstract: A system that enables notification of a critical quota status related to a mail (or Exchange) server is provided. The system can employ parameters directly from a mail server or, alternatively, from a stats store located within a client device to trigger generation and delivery of a quota full (or exceeded) state. This alert can be locally generated within the client device to convey the critical quota status. In operation, the alert protocol can employ most any protocol including but, not limited to, an email, calendar entry, task, instant message (IM), or the like. In the case of an email alert, the system can timestamp the alert thereby making it always appear on the top of the inbox thus, conspicuous to a user.
