  • System and method for event-dependent state activation for a dual-mode mobile communication device
    Patent number: 7231226
    Abstract: A handheld mobile station system capable of automatically answering voice calls is disclosed. The system is comprised of a handheld mobile station, a magnet detection system within the mobile station, a magnet within a mobile station holster located in close proximity to the magnet detection system when the mobile station is stored in the holster wherein the mobile station is operable in a first, second, and third state. The first state occurs when the mobile station is stored in the holster and is ready to receive a voice call. The second state happens when the mobile station is stored in the holster and receiving an incoming voice call. The third state occurs when the mobile station is removed sufficiently out of the holster such that the magnet detection system no longer detects the close proximity of the magnet thereto thereby automatically answering the incoming voice call.

  • MAILBOX POOLING PRE-EMPTING CRITERIA
    Publication number: 20070130273
    Abstract: Mailbox pooling pre-emptive criteria is set forth for use in an adaptive polling system for synchronizing data between a mail server and a mobile communication device. The polling engine stores an indication of the number of messages in the mailbox, the total mailbox size (i.e. the used storage size in bytes), and the last message ID from the last poll. In the next poll, the polling engine retrieves this information from the mailbox and checks against the values stored from the last poll. If the information is the same, then there is no need to compare the message ID list. Whenever either the number of messages in the mailbox or the mailbox size or last message ID has changed, then the full comparison of the message ID list is performed.
