Patent number: 8427489Abstract: 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.Type: GrantFiled: September 20, 2006Date of Patent: April 23, 2013Assignee: Avocent Huntsville CorporationInventor: Ken Matthews

Patent number: 8093748Abstract: The Universal Power Inlet System, or UPIS, is a method of providing universal attachment of 3 different types of electrical power systems into the input circuitry of a Power Distribution Unit, or PDU. This method allows use of either fixed or detachable power cord options permitting the PDU to be powered by any of the following types of electrical power sources: 3-Phase Delta, 3-Phase Star (or Wye) and Single-Phase. This method also describes a way to uniquely identify the specific power system the mentioned PDU is currently attached to. The method also optionally allows derivation of supplementary information about the electrical power system such as current capacity, or ampacity, of the power cord being used. All this information can be used for capacity monitoring and reporting as well as protection of PDU circuitry and power cords.Type: GrantFiled: October 8, 2008Date of Patent: January 10, 2012Assignee: Avocent Huntsville CorporationInventor: Carlos E.

Patent number: 7577255Abstract: 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 pre-process 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.Type: GrantFiled: June 2, 2006Date of Patent: August 18, 2009Assignee: Avocent Huntsville CorporationInventors: Kevin Kerstens, Allan Van Schaick, Jim Doree

Patent number: RE44814Abstract: A system and method for accessing, controlling and monitoring a data processing device in which a video raster signal from the data processing device is analyzed to determine the information displayed on a video display monitor attached to the data processing device is used. The video raster signal is converted to a digital form and a cyclic redundancy check is performed on the digital data to determine the information contained in the video raster signal and to generate a compressed representation of that information. The information may then easily and quickly be transmitted to a remote location for analysis and review. Additionally, commands from the remote location can be transmitted to the system to control the data processing device.Type: GrantFiled: March 4, 2002Date of Patent: March 18, 2014Assignee: Avocent Huntsville CorporationInventors: Ronald J.
