Abstract: A floor cleaning system and a method of cleaning a floor are provided. The cleaning system includes a flat headed mop. The system also includes a frame and at least one compartment removably coupled to the frame. A wringing assembly is fluidly coupled to the at least one compartment, the wringing assembly comprising a fixed extractor element and at least one roller movable from a first position when the mop head is being inserted to a second position when the mop head is being withdrawn.

Abstract: A portable water conditioning system is provided that includes an incoming water inlet; a reverse osmosis stage in fluid communication with the incoming water inlet, the reverse osmosis stage having a permeate outlet and a concentrate outlet; a diversion device having a diversion valve, the diversion valve placing the concentrate outlet in fluid communication with a waste water outlet; a deionizing stage in fluid communication with a pure water outlet; a bypass valve configured to selectively place the permeate outlet in fluid communication with one or more of the waste water outlet, the deionizing stage, and the pure water outlet; and a controller configured to control the diversion device and the bypass valve to provide water at the pure water outlet of a desired condition.

Abstract: Disclosed is a system and method for automated outage and work-flow planning system in a distributed electrical power grid with planned de-energization of electrical equipment as opposed to responding to an unplanned power outage. An automated system provides core conflict resolution and power outage planning. The present invention automatically notifies requestors of upcoming work orders. In addition, the present invention reduces scheduling in efficiencies by requiring requestors to confirm, to decline, or to edit on the fly their pending work order(s). The system also determines if all the orders are not completed and places the order back on the calendar for another day.

Abstract: A tire air pressure system is disclosed for continuously monitoring the pressure of air in an inflatable tire of a vehicle or aircraft, and activating an audio and/or visual alarm when the air pressure drops below a predetermined level. An electrically conducting sensor is attached to a tire valve stem, and a decrease in air pressure causes a normally electrically insulated, spring biased piston to contact the sensor, thereby grounding the piston. The piston is electrically connected to an insulated disk having a conducting ring, mounted between a wheel and a hub. A contact brush disposed at the ring is connected to an alarm maintained at positive potential.

Abstract: An apparatus and method of voice encryption uses segment swapping. Features of the invention include weighting the input time-function segments by a Hamming or Hanning Window function, before converting to frequency domain segments.
