Abstract: The invention is to a method and apparatus for increasing the likelihood that a selected vehicle component has been serviced or checked in a timely manner. An indicator is actuated should the vehicle component not be serviced within a preselected time. The vehicle component is in operable association with a timer, which measures the elapsed time between a starting time and a preselected time. The timer is reset by a switch which is actuated by the servicing of the vehicle component. Should the timer reach a preselected time before the switch associated is actuated, then an indicator is actuated.

Abstract: A system and corresponding method for enhancing hygiene in a food handling environment include an indicator to be worn by a worker in the food handling area, an activating device located outside of the food handling area, a hand cleaning station located proximate or within the food handling area (remote from the restroom), and a deactivating device operatively associated with the hand cleaning station. Upon leaving the food handling area, the indicator worn by the worker is activated when the worker enters a predetermined area proximate the activating device. Thereafter, the indicator is deactivated by the deactivating device only when it is determined that the worker has utilized the hand cleaning station proximate the food handling area. In such a manner, the prior art problem of worker contamination occurring between, for example, the restroom and food handling area is substantially eliminated.

Abstract: A fresh water control system comprises a fresh water supply line having a plurality of spaced outlets. At least first and second fresh water manifolds are provided. Each manifold comprises an inlet in flow communication with an associated one of the outlets and at least a first remotely operable valve for selectively supplying fresh water to a remote fixture. At least first and second check valves are provided. The check valves are intermediate the supply line outlets. Each of the check valves permits fresh water to flow therebeyond in a first direction while preventing water from flowing therebeyond in an opposite second direction.

Abstract: The method of controlling operation of a plurality of fixtures comprises the steps of establishing a maximum fluid flow rate and determining which of the fixtures requires operation. A determination is then made of the fluid flow rate of the fixture requiring operation and a calculation is made of whether operation of the fixture requiring operation will cause the maximum flow rate to be exceeded. The fixture requiring operation is caused to operate if the maximum flow rate will not be exceeded and is prevented from operating if the maximum flow rate will be exceeded.

Abstract: A pinch valve control system for regulating the flow of water through the water distribution network of a building. Remote-controlled, fluid-operated pinch valves are spaced at various locations throughout the water distribution network of the building and may be selectively operated from a remote station to stop the flow of water in any pipe throughout the building's water distribution network. The use of pinch valves permits water flow to be increased or decreased gradually and reduces or eliminates water hammer. The pinch valve is operated by compressed fluid which enters the sleeve around the pinch valve to stop the flow of water in the pipe. To resume the water flow, the fluid in the pinch valve is released.
