  • Patent number: 8954766
    Abstract: Based on bounds of a period of reduced operation for a base device, a base device generates a power management message for transmission to a peripheral device. In the power management message, the base device inserts bounds of a period of reduced operation for the peripheral device. As a result, the periods of reduced operation conserve battery power in both devices and the two devices may reestablish a communications channel upon reaching the end of the period of reduced operation and resuming normal operations.

  • Patent number: 8944336
    Abstract: The described embodiments relate generally to devices, methods and systems for managing access to a memory card, such as a smart card, by a plurality of accessing devices. Certain embodiments relate to a smart card reader (SCR) for managing concurrent access to a smart card by a plurality of accessing devices, the SCR comprising: a processor; a channel manager responsive to the processor for interfacing with the smart card; a communication interface responsive to the channel manager for communicating with the plurality of accessing devices; and wherein, when a session is open on a first channel between a first accessing device and the smart card and the channel manager is configured to issue an open channel command to the smart card to cause the smart card to open a second channel between the smart card and the second accessing device in response to the session request.
