Abstract: An interactive computer system for teaching laboratory-based sciences. According to one embodiment, the system includes a data acquisition module, an internet-based coursework database, and internet-based interactive software tools. Using the interactive software tools, an instructor can select academic course materials and related laboratory experiments from the coursework database. The instructor can create an Internet web page, which provides students with an interactive visual interface with the selected course materials and laboratories, along with various analysis tools. The data acquisition module is located at the site of an experimentation laboratory, and interfaces with laboratory equipment to capture data from selected experiments. Experimental data is transmitted in real-time to an internet-based storage location.

Abstract: A portable lighting system which includes a stand having an adjustable effective length which positions lights carried on a frame at a predetermined vertical position with respect to a supporting surface. The frame is releasably secured to the stand and can readily be set up and dismantled for transport in a compact space. Lights carried by the frame are connected to a foot operated control box which includes switches actuated to energize preselected lights or groups of lights. The energized lights or preselected energized lights can be intensity modulated with a foot operated dimmer while leaving the operator's hands free to play a musical instrument.
