Abstract: A system and method for selectively enhancing an audio signal to make sounds, particularly speech sounds, more distinguishable. The system and method are designed to divide an input auditory signal into a plurality of spectral channels having associated unenhanced signals and perform enhancement processing on a first subset of the spectral channels and not perform enhancement processing on a second subset of the spectral channels. The enhancement processing is performed by determining an output gain for at least the first subset of spectral channels based on a time-varying history of energy of the unenhanced signals associated with each channel in the first subset of the spectral channels and applying the output gain for each of the first subset of the spectral channels to the unenhanced signals to form enhanced signals associated with each of the first subset of the spectral channels.

Abstract: The present disclosure provides a vehicle configured to hold a tool. The toolholder assembly includes a ring and a collar. The ring and collar are both attached to the vehicle adjacent a passenger compartment portion of the vehicle and the ring and collar are spaced apart from each other on the vehicle.

Abstract: The present invention is a drywall spray gun that disperses drywall material that includes a funnel-shaped hopper, a casing that houses a flip lever and a fan, a slide lock trigger and a trigger shield that protects the slide lock trigger from being struck or touched unintentionally and a rechargeable battery pack. The spray gun also includes a removable motor, a forearm rest, an adjustable nozzle and a corresponding stand with a bottom base, an upright vertical backing and a c-shaped top that secures the drywall spray gun in place while the drywall material is poured into the hopper.

Abstract: An apparatus and method for mounting electrical devices in a housing at an angle relative to the ground is provided. The apparatus comprises a housing having a top, bottom, and sides, each of which may be open, closed or ventilated. One or more electrical devices are located in the housing and are oriented at an angle relative to the horizontal ground. The electrical devices may be silicon controlled rectifiers that serve as a power bridge between an exciter and a power generator. A method for mounting electrical devices in a housing at an angle relative to the horizontal ground is also provided.
