J. Boyd Hildebrant's trade show exhibits:
1. Four water cannons shoot streams of water in
feet high and 14 feet wide. The arcs meet in a central collection bowl. The
firing is controlled by four computer-based multi-media interactives. A
fifth computer handles the water management issues and monitors various
points in the system to ensure proper operation. A complex system of five
pumps, five tanks, and hundreds of feet of hose and cable was
designed to be easily set up and just as easily dismantled.
2. Waterfall tradeshow exhibit: A very large V-shaped exhibit 16 feet tall
and 28 feet on a side contained two near straight-drop waterfalls. For
ease of transport, seven individual modules merge seamlessly to become two large waterfalls. Each
module was complete with its own pump, plumbing and controls. Combined,
700 gallons of water cascaded down the waterfalls every minute.
Water Circus tradeshow exhibit: A Rube Goldberg-like collection of
mechanisms were grouped into an all transparent, open-top exhibit to
demonstrate the waterproof characteristics of this manufacturer’s line
of switches. A unique system was designed to drain the exhibit into a
special container in the flight case for transport. A microprocessor
based control system ran all the mechanisms based on switch inputs.
Liquid Level Tanks tradeshow exhibit: A totally closed system of four
vertical transparent tanks demonstrates liquid level
sensors. The tanks fill to sensor level and then drain in a seemingly random
order. Sixteen level sensors interfaced to a purpose-designed
microprocessor based control system.
Liquid Level Tubes: Eight tubes of varying diameters and different materials
demonstrate various sensor technologies, including fiber optics. The
brightly colored liquid “dances” in the tubes as the sensors detect
levels and a purpose-designed microprocessor control system regulates
eight individual pumps. This tabletop application is self-contained and
internally stores the liquid when not in use or in shipment.
ZX Microwave Sensor: Detects liquid levels through two inch thick,
Teflon tank walls. The solid Teflon cylinder was machined to contain the sump,
cavity and the viewing compartment. A second Teflon cylinder was used to
house power supplies, the microprocessor control system and the wiring. This
tabletop demo is self-contained in use, storage and shipment. Filling,
draining and freezing in shipment are all eliminated.
