    Abstract: sistemas e métodos de discriminação de cartões de memória removíveis. são revelados sistemas e métodos de discriminação de cartões de memória removíveis. em particular, as modalidades exemplares discriminam entre cartões digitais seguros (sd) e outros cartões de memória removíveis que se conformam ao fator de forma sd, mais suportam o protocolo de armazenamento flash universal (ufs). ou seja, um hospedeiro pode ter um receptáculo que suporta o fator de forma de cartão sd que é configurado para receber um aparelho. em uso, um cartão de memória removível é inserido no receptáculo e, utilizando um sinal de interrogação compatível com sd, o hospedeiro interroga uma área comum no cartão assim inserido. a área comum inclui informações relacionadas com descritores de capacidade do cartão. um cartão compatível com sd responderá com informações tais como descritores de capacidade sobre as capacidades do protocolo sd, enquanto um cartão compatível com ufs responderá com uma indicação de que o cartão é compatível com ufs. o hospedeiro pode reiniciar então a comunicação com o cartão utilizando o protocolo ufs.

    Abstract: Sistemas y métodos para el reinicio y activación en banda en un bus de audio diferencial. En particular, después de entrar en un modo de baja potencia, un dispositivo maestro abre un drenaje en un transistor que dirige el bus de audio diferencial. Cuando un dispositivo esclavo necesita que el bus se active, el dispositivo esclavo puede hacer la transición del estado del bus. Al detectar la transición del bus, el dispositivo maestro puede reafirmar el control del estado del bus y mantener el bus en este nuevo estado hasta que esté listo para emitir una secuencia de sincronización. Asimismo, un aspecto adicional de la presente descripción proporciona una secuencia distintiva de mantenimiento del bus en un estado predefinido por una duración prolongada interrumpida mediante una inversión relativamente breve del estado que desencadena un reinicio de todos los dispositivos esclavos en el bus de audio.

    Abstract: A PCIe system includes a host system (304) and at least one PCIe endpoint (302). The PCIe endpoint is configured to determine one or more transaction-specific attributes that can improve efficiency and performance of a predefined host transaction. The PCIe endpoint encodes the transaction-specific attributes in a transaction layer packet (TLP) prefix of at least one PCIe TLP and provides the PCIe TLP to the host system. A PCIe root complex (316) in the host system is configured to detect and extract the transaction-specific attributes from the TLP prefix of the PCIe TLP received from the PCIe endpoint. By communicating the transaction-specific attributes in the TLP prefix of the PCIe TLP, it is possible to improve efficiency and performance of the PCIe system without violating the existing PCIe standard.

    Abstract: Techniques for selecting a radio interface for an application are described. A terminal identifies locally-addressable and globally-addressable wireless networks among wireless networks available to the terminal. Radio interfaces supported by the terminal may be prioritized based on the locally-addressable and globally-addressable wireless networks, information obtained for the application, the application type, etc. Different applications may have different radio interface preferences or requirements, which may be considered in prioritizing the radio interfaces. A suitable radio interface may be selected for the application based on the prioritized radio interfaces. WLAN interface may be selected for the application if (a) the WLAN interface is preferred and any WLAN is acceptable to the application or (b) a globally-addressable WLAN is available. A WLAN interface may be selected for the application if a globally-addressable WLAN is not available.
