Patent number: 8788633Abstract: An arrangement for controlling remote devices includes two networked computers. The first computer displays a first file that is stored on the first computer and the second computer displays a second file that is stored on the second computer. The computers send non-graphical commands back and forth to page up or down, zoom, or pan the displayed files in response to commands input into either of the computers. This allows an operator at either computer to view output corresponding to the commands input into the other computer. The first and second files are essentially the same and are retained on the respective computers, so there is no need to send relatively large graphical data packets over the network. Use of relatively small non-graphical data packets reduces the network bandwidth used.Type: GrantFiled: August 2, 2005Date of Patent: July 22, 2014Assignee: Hamilton Sundstrand Space Systems International, Inc.Inventor: David Rosenbush
