  • Patent number: 8832719
    Abstract: An interface system includes a secure digital (SD) driver module to communicate with an SD card over a bus, a secure digital input/output (SDIO) driver module to communicate with an SDIO card over the bus, and an input/output port. A method of operating a host in the interface system includes coupling the bus to the SD card while a first mode is enabled, coupling the bus to the SDIO card while a second mode is enabled, and enabling the first mode in response to a request for access to the SD card. The method includes, while the first mode is enabled, (i) listening for a notification signal arriving from the SDIO card via the input/output port, indicating that an interrupt is pending at the SDIO card, and (ii) in response to the notification signal, enabling the second mode to allow the SDIO card to transmit the interrupt to the host.

  • Patent number: 8706032
    Abstract: Methods and systems are described for providing Bluetooth and Wi-Fi coexistence on an electronic device. Aspects of exemplary embodiments include determining Bluetooth link parameters for a Bluetooth connection and Wi-Fi link parameters for a Wi-Fi connection. Also, a Bluetooth path loss for the Bluetooth connection and a Wi-Fi path loss for the Wi-Fi connection can be determined. According to this embodiment, one or more link conditions, based upon one or more of the Bluetooth link parameters, the Wi-Fi link parameters, the Bluetooth path loss, and the Wi-Fi path loss, may be calculated to determine if simultaneous collaboration between the Bluetooth connection and Wi-Fi connection is feasible. In response to simultaneous collaboration being feasible, the Bluetooth link parameters and the Wi-Fi link parameters are customized based on the one or more link conditions to permit simultaneous collaboration between the Bluetooth connection and the Wi-Fi connection.

  • Patent number: 8528007
    Abstract: A host includes an operating system segmented into a user space and a kernel space with a driver. The user space stores a firmware file and the kernel space includes memory. The driver is stored in the kernel space and performs download cycles to download the firmware file to the memory. The device driver, during a first download cycle, transfers a first block of data to the memory. During each download cycle performed subsequent to the first download cycle, the driver is configured to: identify first and second segments of the memory, where data including the first block of data was stored in the first segment during a previous download cycle; copy the data including the first block of data from the first segment to the second segment; and transfer a block of data of the firmware file, not previously stored in the memory, to the second segment.

  • Patent number: 8380203
    Abstract: A communication device using a current wireless network via a first access point confirms availability of a second access point before breaking the current connection. To confirm availability of the second access point, the communication device sends a power management message that causes the first access point to store packets during the power management period. After the connection to the second access point is confirmed, the second session may be put on hold using the same technique while the connection to the first access point is restored, the stored packets processed and the connection closed. Then the connection to the second access point may be reactivated and further communication made through the second access point.

  • Patent number: 8261257
    Abstract: A host system includes an operating system having a user space and a kernel space with a memory. A device driver performs download cycles to download a firmware file from the user space to the memory. The download cycles are performed based on blocks of data remaining in the user space and not downloaded from the user space. The device driver: transfers a first block of data to a first segment of the memory; transfers a second block of data from the user space to a second segment of the memory; copies the first block into the second segment; and appends the first block to the second block to form a combined block. The first block is transferred from the user space to the first segment during a first download cycle. The first block is transferred from a second segment to the first segment during a second download cycle.

  • Patent number: 8234661
    Abstract: An interface system includes a first driver module that communicates through a bus with a first peripheral card when the bus is in a first mode. A second driver module communicates through the bus with a second peripheral card when the bus is in a second mode. A bus control module receives a communication notification signal from the second peripheral card when the first peripheral card is communicating with the first driver module. The communication notification signal does not interfere with the communication of the first peripheral card and the first driver module. The bus control module switches the bus between first and second modes in response to the communication notification signal.

  • Patent number: 8046776
    Abstract: A method and system for transferring a firmware file between a host system and a device driver, wherein the host system includes an operating system segmented into a user space and a kernel space is disclosed. Aspects of the exemplary embodiment include using a first type of process file system command in the user space to initiate a transfer of the firmware file between the host system and the device driver, wherein the firmware file exists in the user space and the device driver exists in the kernel space; and using a second type of process file system command in the user space to transfer the firmware file between the user space and the device driver in kernel space.
