Abstract: A tradeshow booth is constructed of portions including structural members [10, 28, 44, 56, 56a, 72, 103]. Each of these portions are constructed of laminated cardboard or other similar easily recyclable material, Vertical L-shaped beam members [74] connect upper and lower structural members together to form portions of a tradeshow booth. The individual portions are in turn connected together using U-shaped connectors [68], and which may be locked in place by gussets [62]. A decorative or advertising display covering [90] covers the assembled portions. Significantly, the entire tradeshow booth is extremely lightweight and strong, and may be assembled entirely by hand without using tools of any kind.

Abstract: An interactive exercise system including exercise equipment having a resistance system, a speed sensor, a controller that varies the resistance setting of the exercise equipment, and a playback device for playing pre-recorded video and audio. The controller, operating in conjunction with speed information from the speed sensor and terrain information from media table files, dynamically varies the resistance setting of the exercise equipment in order to simulate varying degrees of difficulty while the playback device concurrently plays back the video and audio to create the simulation that the user is exercising in a natural setting such as a real-world exercise course.
