Patent number: 8443037Abstract: A computerized switching system for coupling a workstation to a remotely located computer. A signal conditioning unit receives keyboard and mouse signals generated by a workstation and generates a data packet which is transmitted to a central crosspoint switch. The packet is routed through a crosspoint switch to another signal conditioning unit located at a remotely located computer. The second signal conditioning unit applies the keyboard and mouse commands to the keyboard and mouse connectors of the computer as if the keyboard and mouse were directly coupled to the remote computer. Video signals produced by the remote computer are transmitted through the crosspoint switch to the workstation. Horizontal and vertical sync signals are encoded on to the video signals to reduce the number of cables that extend between the workstation and the remote computer.Type: GrantFiled: September 21, 2010Date of Patent: May 14, 2013Assignee: Avocent Redmond Corp.Inventors: Danny L. Beasley, Robert V. Seifert, Jr., Paul Lacrampe, James J. Huffington, Thomas Greene, Kevin J. Hafer

Patent number: 7136946Abstract: A method and system for converting the output of a communications port (e.g., a serial port or a USB port) into video signals representing the output of a terminal using a KVM switch. Upon receiving characters from the communications port, the system interprets the characters as terminal emulation commands and internally generates a representation of what a resulting terminal screen would look like. From that internal (digital) representation, the system produces analog outputS representing the terminal screen. The analog outputs are output on the monitor attached to the KVM switch.Type: GrantFiled: April 8, 2003Date of Patent: November 14, 2006Assignee: Avocent Redmond Corp.Inventor: Timothy C. Shirley

Patent number: 6701380Abstract: A method and system for remotely accessing and controlling at least one of a target switch and a target computer using a target controller. The video information captured by the target controller is analyzed and compressed in order to reduce network traffic between the target controller and a controlling computer.Type: GrantFiled: February 13, 2003Date of Patent: March 2, 2004Assignee: Avocent Redmond Corp.Inventors: Walter J. Schneider, Warren C. Jones, Mark D. Sasten
