A method and system for managing power in a computer system is disclosed. The computer system includes a host. The method and system include providing a Universal Serial Bus (USB) hub, at least one USB connector and attach/removal detection logic. The at least one USB connector is coupled with the USB hub. The attach/removal detection logic is coupled with the USB hub. The attach/removal detection logic determines whether a USB device is connected to the at least one USB connector, logically decouples the USB hub from the host if the USB device is not connected to the at least one USB connector and logically couples the USB hub to the host if the USB device is connected to the at least one USB connector.

In a notebook type computer terminal, a plate type slot antenna is provided between a display panel and a surrounding wall of a display panel housing so that a radiator portion thereof is projecting from a frame of the display panel and a stay, which are made of conductive material by a length more than a predetermined dimension S. A ground portion of the antenna is connected not only to a ground of a radio transceiver unit but also to the display panel housing made of conductive material through the stay.

Display device, computer terminal, and antenna

Described is a substrate connector assembly which includes a first circuit substrate, a second circuit substrate and a connector mounted on the first circuit substrate for connecting wiring patterns formed on the first circuit substrate with wiring patterns formed on the second circuit substrate. The first circuit substrate includes first wiring patterns capable of being connected to external wirings and second wiring patterns in a second wiring area apart from the first wiring patterns by a predetermined creepage distance to provide a sufficient isolation. The connector includes a contact array of a plurality of contacts, and a key which is formed at a position for separating the plurality of contacts of the contact array into a first contact group and a second contact group for (1) preventing a misconnection of the second circuit substrate and (2) separating the first wiring patterns from the second wiring patterns by the predetermined creepage distance. The first contact group is connected to the first wiring patterns and the second contact group is connected to the wiring patterns in the second wiring area.

It is to provide a sub-card board connector capable of secure grounding and also easy placement and removal of a card, a sub-card board, a modem sub-card, and a computer having this connector. In sub-card board connector,of the present invention, (1) first GND connections,-,-,are placed on a surface facing the sub-card board,of the latches,-,-,and when connecting the sub-card board to the connector, the sub-card board is grounded by having the first GND connections contact the first electrodes provided on the sub-card board; and/or (2) second GND connections,-,-,are placed facing the sub-card board on a surface opposite to the latches of the latch supporting parts,-,-,and when connecting the sub-card board to the connector, the sub-card board is grounded by having the second GND connections contact the second electrodes provided on the sub-card board. And this connector is incorporated in a computer.
