Abstract: A rail charger system used to charge multiple battery assemblies which are, in turn, used to charge electronic devices. The multiple battery assemblies slide on and off a rail charger. The rail charger charges multiple batteries at one time. Alternative embodiments of the rail charger system may be used for charging one or two battery assemblies.

Abstract: A control system for minimizing overall water use in a food waste handling system while maximizing flow rate when needed by controlling a flow of water into the handling system based on or in response to a physical presence of an operator. The control system substantially automatically senses, detects, or otherwise determines the presence of the operator, wherein such presence is assumptively associated with use of the waste handling system (i.e., the deposition of waste thereinto), and, in response to said presence, automatically controls the flow of water accordingly and for a pre-established period of time following cessation of said presence in order to facilitate the on-going handling process.

Abstract: An improved system, which conserves both energy and water, is provided for disposing of waste materials in environments such as restaurants and institutional food serving facilities. A commercial type food disposer unit having an electric motor for powering a mechanism for grinding or comminuting waste food materials and requiring running water for lubrication, flushing and/or cooling purposes is provided with an electric control circuit for automatically operating the motor and water supply valves associated with the unit in manner assuring both more efficient operation of the unit and minimum usage of electrical power and water.
