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： 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： In some embodiments, if a card in a card reader has not been accessed in a first specified amount of time, the card may be powered down. The card may be powered back up if an attempt is made to access the card. In some embodiments, if a memory card is in the memory card slot of the card reader, but has not been accessed in a second specified amount of time, the card reader may be electrically disconnected from the host controller if a sideband signal is available to signal the card reader when to electrically reconnect.

摘要： A keycode translation system is disclosed in the form of a hardware system for providing translation between the keycode sent to the keyboard controller of a computer, such as a personal computer, and the code sent from the keyboard controller to the CPU of the computer for processing. A control ROM is used to select translated keycode signals from a keycode look-up table under the control of a program counter and keycode signals from the keyboard. These translated signals then are supplied through an accumulator to the CPU of the computer.

摘要： A switched capacitor operational amplifier circuit which has both AC and DC precision and which substantially eliminates parasitic capacitance effects is provided. The operational amplifier circuit utilizes compensated CMOS transmission gates and a structure which switches a parasitic diffusion capacitance between two points of equal voltage potential thereby preventing a charge transfer which would create an offset voltage error.

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。
