摘要:
The display of a notebook computer includes a privacy filter extending over the display screen to limit the viewing angle within which the image on the screen can be discerned. To allow for normal viewing when the privacy feature is not required, the privacy filter is movable from the screen by sliding into a cavity extending from one side of the screen to be rolled onto a roller or to be stored partly behind the screen. Alternately, a privacy filter is provided that is electrically switchable between a mode in which the viewing angle is limited and a mode in which normal viewing is permitted. The movable privacy filter includes closely spaced louvers surrounded by clear plastic or, alternately, a polarizer. The switchable privacy filter includes a liquid crystal device and a polarizer.

A first device captures session data for each application session that is executing on a first device, and provides the session data to a second device in order for the second device to reconstruct the application sessions. A first device identifies one or more application sessions currently executing on the first device. Each of the application sessions include a media object and session data, which includes a media object identifier that corresponds to the media object and a first device media session position. The first device captures the session data transmits the captured session data to one or more second devices. The second devices are adapted to reconstruct at least one of the application sessions using the received session data and positions the application sessions at a second device media session position that corresponds to the received first device media session position.

A low power processor in a computer is kept energized in a suspend state in which a main processor of the computer is deenergized. The low power processor maintains a network connection by sending keepalive packets as required by the network communication protocol.

A device that requires a regulatory label includes a label affixed to a surface of the device and a marking mechanism in the device that detects a configuration setting associated with the device and alters a portion of the label based on the configuration setting such that the label indicates information related to the configuration setting of the device.

Communications are provided for wide-channel and narrow-channel wireless devices within a common area over a number of channels within a common radio frequency band. Since communications using a wide-channel wireless signal interfere with at least two channels over which communications using narrow-channel wireless signals can occur, wide-channel communications are established only when it is determined that a wide-channel wireless device is present within the common area.

A hard disk drive unit includes a microprocessor programmed to erase data stored within the drive unit if it is determined that a process potentially leading to a misuse of the data stored within the drive unit, and if secure disposal configuration data stored in nonvolatile storage within the drive indicates that the data is to be erased. Such a process includes initializing the drive unit for operation without providing a password matching a password stored in the drive unit, initializing the drive unit in a system not having CMOS configuration data matching the drive unit, and determining that a failure rate within the drive unit exceeds a threshold level.

This disclosure relates to a computer system having a peripheral component interconnect (PCI) and expansion bus riser card having at least one expansion bus slot and at least one PCI slot, the latter of which meets a PCI bus stub length requirement. The PCI slot is connected to the PCI bus by a plurality of PCI stub lines. Each of the plurality of PCI lines does not exceed a predetermined length. The expansion bus is divided into a first section having a first plurality of lines and a second section having a second plurality of lines. The plurality of PCI lines are disposed between the first and second plurality of lines of the expansion bus such that all of the plurality of PCI lines from the riser card to the PCI bus do not exceed the predetermined length.
摘要:
An I/O housing holds an I/O port and is pivotable between a housed position, wherein the I/O housing is held snugly flat in a chassis of the computer, and an extended position, wherein the port end of the housing is distanced from the chassis. The I/O housing can mechanically engage an I/O device with the port establishing communication between the I/O device and the computer processor.
摘要:
An arrangement facilitating the connection of a client to a network through an access point, particularly in an area with overlapping 0.11n channels. Preferably, a client may communicate with two access points and “ask” one of them to stop transmitting long enough so as to facilitate communication with the other access point. Current specifications otherwise provide no workable arrangement for handling overlapping channels.
摘要:
A method, computer program product and system for handling the use of multiple 802.11n channels in a location where there are a small number of available channels. An access point (“access point A”) having a client (“client A”) located solely within its coverage area and another client (“client B”) located within its coverage area and a coverage area of an adjacent access point (“access point B”) may receive a request to hold back 802.11n traffic from client B. Client B sends such a request since it is prevented from communicating with access point B using the 802.11n standard due to the interference from access point A communicating with client A using the 802.11n standard. As a result, access point A switches its standard of operation from using the 802.11n standard to communicate with client A to a standard that uses a bandwidth of 22 MHz (e.g., 802.11b, 802.11a, 802.11g standards).
