  • Patent number: 8805426
    Abstract: A communication device is configured to receive messages. The communication device may comprise a display screen upon which messages are displayed. A microprocessor configured to execute at least one message management program on the communication device, filters incoming messages. The message management program comprising a message filter application filters received messages based on a comparison of sender identification data associated with a received message to approved sender identification data.

  • Patent number: 8621169
    Abstract: A method for dynamically (i.e., upon boot) rewriting, in a failure resistant manner, of part of, or the entirety of, the flash memory for a device allows for a changing of location for logical blocks of execute-in-place code. Conveniently, the rewriting results in a randomization, of varying degree, of the address space layout upon each boot up cycle.

  • Publication number: 20120292393
    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.

  • Patent number: 8240578
    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 for managing concurrent access to a smart card, wherein when a channel manager receives a close session request from a first accessing device, and a first session is open on a first channel for the first accessing device and a second session is open on a second channel for a second accessing device, the channel manager is configured to: issue a close channel command to the smart card to close the second channel; issue the close session request from the first accessing device to the smart card; and issue a further session request to the smart card to re-open the first channel, and continue the second session on the re-opened first channel.

  • Patent number: 8128002
    Abstract: A computerized device has an open communication session with a smart card via a smart card reader. The smart card reader and the computerized device cooperate to enable another computerized device to communicate with the smart card over the open communication session. Communication between the other computerized device and the smart card is routed via the computerized device that has the open communication session.
