Abstract: A modular laboratory automation system for monitoring and controlling laboratory experiments, the modular laboratory automation system including a controller, an interface board, and a portable power supply. Power levels of standard laboratory equipment can be automatically controlled, and conditions and parameters of experiments can be automatically monitored and recorded. The laboratory automation system is modular and can be configured to operate with laboratory experiments having varying setups and equipment.

Abstract: A portable power supply for controlling laboratory experiments, the power supply includes input terminals that receive control signals and power terminals that supply power to laboratory devices. The power supply enables power levels of standard laboratory equipment to be automatically controlled.

Abstract: A uniquely designed device for retaining a trouser on a wearer includes a base plate having inner and outer pairs of geared channels extending from one side to the other. A belt loop clasp extends from each side of the base plate. Each clasp includes a hook portion with a pair of arms extending therefrom each of which is slidably received within a designated channel. Each arm includes teeth thereon for interlocking with the geared surface within its corresponding channel. Each of the hooks are secured about a trouser belt loop and the arms are pressed into the base plate until the trouser waist band is sufficiently tight.
