Abstract: In a keyboard-video-mouse (“KVM”) system in which a target computer may be wirelessly accessed by a plurality of remote stations, a method includes, by the target computer: obtaining a frame of video data; transmitting packets for the frame; transmitting a query packet; obtaining a list of requests from at least one of the remote stations, each request from a particular remote station identifying packets missed by that particular remote station; and resending at least some of the requested packets.

Abstract: A remote administration system's ability to communicate with remote computers using in-band communications is contingent on many factors (e.g., the operability of the network over which the in-band communications is carried and, to some extent, the correct operation of the software on the remote computer). Accordingly, there may come a time (e.g., during a network outage) where the remote administration system can no longer communicate with the remote computer over the preferred communications protocol (e.g., using in-band communications). In such a case, a status detector of the remote administration system may detect that an error has occurred (e.g., by “pinging” the remote computer and getting no response or by losing an open network connection) and then switch to a less preferred communications protocol (e.g., using out-of-band communications).

Abstract: A method, system and apparatus are described for avoiding the use of a web-server or generic security when providing network administration services remotely to managed entities using wireless technology. Instead a true Proxy device, not operating as a web-server, is used to preprocess all command traffic from wireless input devices (WID). The intervention between the WID and the managed entities of the Proxy isolating the managed entities from the WID, enhanced by encoding using a novel messaging protocol, further enhanced by a novel security model based on multiple pre-shared keys and algorithms together with identifiers and passwords that are not transmitted, achieves several bandwidth and security advantages including the ability to deliver TELNET services across the Internet and behind a firewall.

Abstract: A high definition video transmitter and receiver are disclosed. The transmitter provides high definition video to a one-point receiver or to multipoint receivers. The transmission network is asynchronous and the receiver re-synchronizes the video. The transmission can be wired or wireless.

Abstract: In a virtualized desktop system an interfacing module is coupled to peripheral ports of a target device. The interfacing module is connected to a network. A digital user station is connected to the network. The digital user station is configured to be coupled to peripherals. The interfacing module and digital user station use respective hardware engines to communicate via said network.

Abstract: There is provided a novel system and method for delivering messages using alternate modes of communication when a primary mode of communication is not available as may happen in emergent circumstances such as those that arise during a terrorist attack causing damage to communications infrastructure.

Abstract: A power distribution unit that switches off power outlets in the event of an over-current condition by using circuitry that measures how long input current has exceeded a threshold and sending a reset signal to the power outlets when input current has exceeded the threshold for a predetermined time duration.

Abstract: A remote access device is disclosed for capturing, digitizing and communicating video signals from a host computer to a remote computer. The remote computer returns keyboard and mouse signals through the remote access device to the host computer to control the host computer as though the remote keyboard and mouse were directly connected to the host computer. The remote access device includes a circuit module interface for the host computer that allows the remote access device to operate independently of any operating system characteristics associated with the host computer.

Abstract: Rack Interface Pods can be augmented with non-KVM (keyboard, video and mouse) functionality that can enable greater analysis of the state of the computer to which the RIP is attached. A RIP can be augmented to include a non-KVM input connection (e.g., an Intelligent Platform/Chassis control protocol input) that is used to communicate between the server and the RIP. The RIP can then multiplex the received information with the KVM signals for transmission to a PEM or to an ARI port. Video and computer environment-style data can be multiplexed across a communications medium exiting the RIP such that they can be received by a remote computer.

Abstract: A network interface is described in which a single computer bus is split over a long distance into two or more inter-communicating buses. On one bus, processing and applications are provided and on the other remote bus, peripheral and local controllers are provided. The buses communicate through a series of: bridge, FPGA, FPGA and bridge. Between the FPGAs, a communication path provides long distance communication.

Abstract: A method and system to detect a correlation of movements of an input device, sent from a first location, with at least one configurable movement parameter set on a remote computer at a second location remote from the first location, wherein the method includes: (a) sending first movement information from the first location to the remote computer at the second location, the first movement information corresponding to a first movement of the input device; (b) tracking a resulting movement of a cursor of the remote computer at the second location in response to the remote computer having received the first movement information and utilized the at least one configurable movement parameter; (c) calculating predicted movements utilizing at least two possible values for the at least one configurable movement parameter; and (d) determining which of the at least two possible values provides the predicted movement most closely matching the resulting movement of the cursor.

Abstract: A two-stage pixel skew compensation circuit for use with digital display monitors. The first stage of the compensation circuit aligns the edges of the pixels received on the color component signal lines of an analog video signal. The second stage of the de-skew compensation circuit realigns the pixels themselves so that no skew exists between the digitized video color components. The digitized video signals drive a digital video monitor.
