Patent number: 6826267Abstract: Appliances (102, 102, 106 and 108) are controlled by providing a source (2016, 112) of command fields (CMD, FIG. 2) that include a context subfield (Community, FIG. 4) defining operating modes and a command subfield (Command, FIG. 4) defining operations to be performed within the context subfield. A network (119) transmits the command fields between the source and the appliance. A controller (112, 116) processes the command fields so that an operation defined by one of the command subfields is performed.Type: GrantFiled: July 12, 2001Date of Patent: November 30, 2004Assignee: General Electric CompanyInventors: Wolfgang Daum, John Steven Holmes, William Hull Bicknell, Scott Alan Horning, Tanveer Iqbal, John Kenneth Hooker, Robert Marten Bultman, Ziqiang Hu, Scott Charles Evans, John Erik Hershey
