Abstract: A smart cellphone application is used as sound pressure level meter for determining if ambient noise infringes the legal limit, and sends evidence to prove the infringement to the law enforcement agency. The application play in the speaker at least one reference burst tone, and use Fast Fourier Transform (FFT) to achieve the mentioned functionality.
Abstract: Systems, apparatus and methods for treating a contaminated fluid stream are provided. The systems may include a treatment column fluidly interconnected to a regeneration column, the regeneration column being adapted to continuously receive solid spent media from the treatment column to continuously regenerate such solid spent media.

Abstract: The invention is a detection and prevention system to detect and prevent fluid leaks in a property that may cause damage to the property. The sources of the leaks may include, for example, toilets, hot water heater, sinks, washing machines, water makers and broken pipes or other sources of fluid leaks. The inventive may include one or more sender units that may be positioned at various locations on a property. The sender units may have a fluid sensor (for detecting a fluid leak) and a transmitter (for communicating with a base unit). The base unit may receive signals from the transmitter when the fluid sensors detect a fluid. The base unit may then communicate with a main shut off valve to restrict the flow of fluids onto the property.

Abstract: The invention is a multiple size workpiece positioning device for the precise positioning or centering of workpieces, such as semiconductor wafers, in a processing station. The inventive includes a plurality of ring bars that may be pivoted on one end. The distal end of the ring bars form a circular shape that may decrease or increase in diameter as the ring bars are pivoted. This movement may be used to position or center the workpiece. A single combination pin or two pins of different heights may be mounted on the distal end of the ring bars. A combination pin or a rest pin and an alignment pin may be used to support the bottom of the workpiece to provide a contact point for an urging force on the edge of the workpiece.
