  • Patent number: 8374618
    Abstract: A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. A control strategy may be employed to manage both more predictable and more spontaneous wireless communication mediums, wherein a local controller may be employed in a radio module utilizing an unscheduled wireless medium, like WLAN, for determining whether adequate time has been allocated to complete a transaction. If the transaction cannot be completed in the allowed time, it may be delayed until adequate time exists, and the delay may be reported so that the time may be reallocated to other radio modules. The radio module may then enter a power-saving mode until the transaction can be completed.

  • Patent number: 7680520
    Abstract: The present invention relates to systems and methods for a implementing an optimized power conservation communication protocol, wherein the communication link is flexible and the power consumption characteristics are optimized. One facet of the system's flexibility relates to the system's ability to negotiate device control roles associated with a polling communication link. Also, once the device control roles are in place and the communication link is established, the system selectively implements a number of polling protocols for a multitude of applications that need a low power consumption. In some embodiments the system maintains a communication link with a reduced frequency polling protocol. This type of communication link maintains efficient power consumption characteristics, as well as, connection times that are faster than establishing a communication link between disconnected devices.
