摘要： In various embodiments, a wireless host and a wired host may communicate with downstream devices through a USB switching hub. A wireless host/wireless bridge may be temporarily physically coupled to an upstream port of the USB switching hub to complete association with another wireless bridge coupled to the USB switching hub as a downstream device through a downstream port. During association, the host and downstream wireless bridge may exchange an encryption key to be used for future wireless communications. After association, the wireless host may be disconnected from the USB switching hub to communicate remotely. In some embodiments, the wireless host may not need to be physically coupled to the USB switching hub during association.
摘要翻译：在各种实施例中，无线主机和有线主机可以通过USB交换集线器与下游设备进行通信。无线主机/无线桥可以临时物理地耦合到USB交换集线器的上游端口，以通过下游端口作为下游设备完成与耦合到USB交换集线器的另一无线桥接器的关联。在关联期间，主机和下游无线网桥可以交换要用于将来的无线通信的加密密钥。关联后，无线主机可能与USB交换集线器断开连接以进行远程通信。在一些实施例中，在关联期间，无线主机可能不需要物理耦合到USB交换集线器。

摘要： If a USB device is turned off or is not active, the device may be electrically disconnected from a USB host controller. The device may be electrically disconnected through a physical interface on the device. In some embodiments, if the device becomes active during a wait period (e.g., 2–3 seconds) prior to electrically disconnecting the device, the device may not be electrically disconnected. In some embodiments, when the device is electrically disconnected from the USB host controller and no system activity of a bus mastering peripheral is occurring, the CPU may enter a low power state if other conditions are met. In some embodiments, if the USB device becomes active after electrically disconnecting, the electrical disconnection may be discontinued.
摘要翻译：如果USB设备已关闭或未激活，则设备可能与USB主机控制器电气断开。该设备可以通过设备上的物理接口电断开。在一些实施例中，如果在电气断开设备之前的设备在等待期间（例如2-3秒）期间变得有效，则该设备可能不会被电断开。在一些实施例中，当设备与USB主机控制器电气断开连接并且没有发生总线母盘制作外设的系统活动时，如果满足其他条件，则CPU可以进入低功率状态。在一些实施例中，如果在电断开之后USB设备变为有效，则可能停止电断开。

摘要： A drive controller for controlling multiple disk drives is disclosed. In one embodiment, the drive controller includes a physical interface circuit configured for coupling to a peripheral bus. A plurality of serial interface engines may be coupled to the physical interface circuit. A buffer may be coupled to each of the plurality of serial interface engines and an interface controller. The interface controller may be configured for coupling to a plurality of disk drives. Since the drive controller includes only a single physical interface circuit, a single buffer, and a single interface controller, its complexity is reduced to near that of a single drive controller while being capable for simultaneously providing interfaces for each of a plurality of disk drives.

摘要： A transformer with a high permeability core is substantially prevented from saturating by a symmetry correction circuit which senses the total flux density change of either a positive or negative polarity and balances the total flux density change of the opposite polarity to thereby provide symmetrical positive and negative changes in the flux density of the transformer. The symmetry correction circuit integrates the voltage from a winding of the transformer to determine the total flux density change of a given polarity during the application of a voltage of one polarity. The duration of the voltage of the opposite polarity is controlled by the symmetry correction circuit such that the net voltage-time integration of the two applied voltages is substantially equal to zero.

摘要： In various embodiments, a computer system may include a computer controller to send and/or receive sideband signals to/from a USB device. In some embodiments, the USB device may include a USB controller to send/receive sideband signals to/from the computer controller. The computer controller and USB controller may allow communications between the computer system and the USB device when either of the computer system or USB device is in a low power state. The sideband signal sent between the computer system and the USB device may trigger the other of the computer system or USB device to enter a normal power state. In some embodiments, the computer controller and/or USB controller may be further coupled to a memory to buffer data to be sent to the computer system or USB device after the computer system or USB device returns to a normal power state.

摘要： A system for automatically switching peripheral connectivity between two host devices based on respective connectivity of the hosts. The method may be used where peripherals are usually attached to one host and are automatically switched to a second host when the second host is attached to the system. A USB switching hub may be operable to automatically switch connectivity of the peripheral device(s) from the first host device to the second host device when the second host device is connected to the USB device. This automates the process for the end user when normally all peripherals are attached to one host, and some or all peripherals are shared with a second host when the second host is attached.

摘要： A system and method for automatically switching display of video signals between a first device and a second device. The system may include a display device with display circuitry for displaying an image on the display in response to a received video signal. The display device may include a first video input port for receiving a first video signal from the first device and a second video input port for receiving a second video signal from the second device. Additionally, the display device may include detection circuitry coupled to the second video input port for detecting the second video signal from the second device, and switch circuitry operable to automatically provide connectivity between the second video input port and the display circuitry to enable display of the second video signal in response to the detection circuitry detecting the second video signal from the second device.

摘要： In various embodiments, icons, specific to a type of memory card (e.g., a flash memory card) inserted into a card reader may be displayed. In some embodiments, the card reader may be electrically connected to the host controller each time a memory card is inserted into the card reader. In various embodiments, different device identifications may be reported as if the card reader were actually several different card readers each dedicated to a different memory card type. A registry of an operating system may be preloaded with a different icon for each of the different card reader types. An icon may be displayed on a display specific to the type of memory card inserted. When the memory card is removed, the card reader may be electrically disconnected and the displayed icon may be removed or replaced.
