Abstract: A power management method is disclosed. The power management method comprises the step of a computer system checking existence of a manufacturing identifier (ID) of a human interface device (HID) when the computer system is operated in a first mode; the computer system continuously detecting whether the HID exist when the manufacturing ID exists; the computer system starting a timer when the computer system detects that the HID does not exist; the computer system entering a second mode when the timer expires; the HID determining whether the computer system is operated in the second mode, when plugged into the computer system; the HID performing state transition on the computer system when determining that the computer system is in the second mode; and the computer system entering the first mode when detecting the state transition.

The file managing method comprises steps of: detecting whether the first electronic device is connected to the second electronic device; uploading a file to be processed from the first electronic device to the second electronic device while the first electronic device being connected to the second electronic device and being operated by inputting a command for processing the file on the first electronic device; sending the command to the second electronic device; and performing the command on the uploaded file by the second electronic device.

Abstract: The method disposes a power-swicthable USB port in a host, which is connected to a USB device. The relay has a control pin controlled by the host and two switch pins electrically connected between a power pin of the USB port and a power source of the host. The host sends a control signal to the control pin of the relay to close the switch pins when the USB port is held normal by a user. The host sends another control signal to the control pin to open the switch pins and cut off the power to the USB port when the user is logically disconnecting the USB device from the host.

Abstract: An operation method for a first host apparatus is provided by the present invention. First, the operation method captures an event of the first host apparatus, so as to generate an event information. Then, the event information is transmitted to a second host apparatus, so as to control the second host apparatus.

Abstract: A CWUSB, ExpressCard card has a body with an internal slide in the form of a deep rectangular slot. Accommodated in the slot is an aerial unit in two parts pivotally connected together. The slot has sides to the slot and slightly over-hung ends. The first part has a major portion with a width to slide in the slot and a minor portion with a reduced width that is able to protrude between the over-hung ends in an extended position of the aerial unit. The minor portion has pivot points. The second part is longer and has the reduced width whereby it can pass between the overhung ends. The inner end of the second part has complementary pivot points, whereby the parts are pivotally connected. The parts molded to locate a torsion spring, which biases the second part upwards with respect to the first part.

Abstract: A notice method for e-mail is provided by the present invention. The notice method of the present invention first checks whether or not a user sends an e-mail to a recipient. When the notice method checks that the user sends the e-mail, a notice message is sent to the recipient's phone from the user's phone for noticing the recipient that the user already sends the e-mail.

Abstract: A mother board compatible with multiple versions of universal serial bus (USB) is disclosed. The motherboard comprises a connector, a host controller interface (HCI) means, a serial bus slot, and a detection unit. The connector is used for exchanging signals of a first USB version and signals of a second USB version with an external USB device. The host HCI means is coupled to the connector through a first data line, for proving the signals of the first USB version. The serial bus slot is coupled to the connector through a second data line, for conveying the signals of the second USB version. The detection unit is coupled to the serial bus slot for detecting an insertion state of the serial bus slot and the functionality of the second USB version, and generating a detection result.

Abstract: An AIO PC has its LVDS link or interface, between the mother board and the LCD, modified by the insertion of an LVDS Switch which can connect to a second LVDS source such as LCD controller which takes its input from a socket mounted on the housing of the AIO PC. The LVDS switch and LCD controller are located within the enclosure or housing of the AIO PC. The LVDS switch is controlled by a physical electromechanical switch.

Abstract: An all-in-one computer has a switch button is exposed on the front of the housing for a KVM switch, that is a switch for switching manual input data and VDU data. The KVM switch has a keyboard data input connection, a mouse data input connection, and two VDU data input connections. It has two keyboard and two mouse data output connections and one VDU data output connection. It connects a keyboard and mouse to either of the all-in-one computer and an external, laptop computer and either of their VDU data signals to the all-in-one's VDU.

Abstract: A CWUSB interface 1 is shown installed in a printer 2. The interface allows a computer 3 to send print data to the printer, either wirelessly or in a hard wired manner, for which the computer has an auxiliary communication card 4 having an aerial 5 and the usual Type A USB socket 6. A cable 7 is provided for wired connection. The interface 1 has a WUSB controller 8 with an aerial 9 connected to it, which can co-operate with the aerial 5. The interface also has a Type B USB socket 10 for wired connection. A peripheral device controller 11 is connected to either of the socket 10 or the WUSB controller 8 via a pair of switches 12,14. These are under control of the WUSB controller. Being a wireless device, it can communicate with the computer only if the interface is associated with the computer, that is to say the computer as its host has recorded the full ID of the interface, the interface has recorded the full ID of the host and the host and interface have exchanged encryption keys.

Abstract: A hub has a case with an up-stream Type A USB socket in a top surface and four down-stream Type A sockets in the side surfaces. The hub has internal circuitry interconnecting the ports. Unconventionally for a USB up-stream port, the power contacts of the Type A up-stream socket are provided with a voltage across them for powering the transceiver. However, this is switched off as follows to allow wired transfer of data from the computer, without voltage being passed back the computer.
