Abstract: A sanitizer dispenser unit is mounted on escalator handrails, moving walkway railing or any revolving handrail. It would mount either on the in-going or out-going portion of the handrail, and would continuously sanitize the surface of the handrail with a micromist and be easily refillable by maintenance personnel.

Abstract: A backup power system is connected in parallel to a load, which is powered via a power line connecting that load to a main power source, such as a utility. The backup system includes a generator/condenser unit that is coupled to a flywheel unit to maintain the flywheel of that flywheel unit rotating at a preset speed during normal power system operation and is also connected to a thermal engine to supply power to the load via the generator/condenser unit when there is an interruption of power from the main power source. A shaft-coupling unit couples the generator/condenser unit to the flywheel unit. The shaft-coupling unit includes a sensor plate. When there is a difference in rotational speed between the flywheel and the motor/generator, as would be caused due to a main power unit operating at a level other than a predetermined level, this differential rotational speed is translated by the coupling unit into linear movement of the sensor plate.
