Abstract: An integrated controller for an operator unit for powering an overhead garage roller door or roller shutter is described. The operator unit comprises a motor, an output drive assembly, a timing assembly unit, and a clutch assembly for providing selective engagement between motor powered operation and manual operation (provided by a chain rotating a chain wheel). The motor is arranged to drive a shaft which, in turn, provides drive to the roller door or shutter assembly (not shown), which includes an axle around which the roller door or shutter is wound. The integrated controller comprises an inverter for receiving a single phase power supply and supplying three phase power to drive the motor; and a drive controller in operable association with the inverter for providing active management of the operation of the motor.

Abstract: The invention is a portable laboratory instrument that incorporates software designed to record laboratory tests results to analyze the biomass of a Wastewater Treatment Plant (WWTP) using an Activated Sludge Process. The software uses the values entered by the user and its data bank/algorithms to determine the health/age of the biomass. It produces an interpretation of the collected data, and delivers a final set of instructions based on the overall health of the Wastewater Treatment Plant (WWTP). The final result is delivered using simple instructions and color coded lights for an easy and quick interpretation. Its use does not require extensive training in the field of wastewater treatment. Its purpose is to prevent environmental disasters by detecting current/future biological problems.
