Abstract: A method of the invention can be used to select a part from a computer-aided design (CAD) display on a client device, and to generate an electronic purchase order with a server through interaction of the client device and server over a network. The CAD display can be generated by the client device with a browser that has a CAD display plug-in module to permit display of a CAD drawing. The CAD drawing can display part(s) associated with reference(s), and part data accessible to the server can be stored in association with such reference(s). Upon the user's selection of a part having a reference, the client device transmits this reference to the server via the network. The server receives the reference and uses it to access the part data for generation of the electronic purchase order. The part data can include part identification data and price data for the selected part. The part can be for an automobile, truck, boat, aircraft, or machine, for example.

Abstract: A system for controlling a video-conference network by the end user at a video conference site which is comprised of a public telecommunications network connected to video-conference controllers at the video conference sites. The video-conference controllers allow the end user to issue single commands which initiate an automated sequence resulting in implementation of the end user command. The commands are designed to provide the end user with real time control of video-conferencing.
