Abstract: A pump panel training device is provided and includes a plurality of simulated gages operable to imitate gages upon a fire truck pump panel, a plurality of simulated controls operable to imitate controls upon the fire truck pump panel, and a simulated water hose operable to imitate one of water temperature changes, water temperature pressure, and water hose vibration for the fire truck pump panel.

Abstract: A headphone set includes a head band and a pair of speaker assemblies supplied on opposite ends of the headband. Each of the speaker assemblies comprises an earphone speaker for reproducing sound to be directed toward one of the wearer's ears, a relatively larger and more powerful broadcast speaker for reproducing sound to be broadcast in the vicinity of the headphone set; and an expandable speaker enclosure for supporting the earphone speaker and the broadcast speaker. Each speaker enclosure defines a sound chamber having an enclosed air volume for improving the acoustical characteristics of the headphone set and each speaker enclosure is shiftable between a collapsed configuration and an expanded configuration. When the speaker enclosures are shifted to their expanded configurations, the sound chambers have a relatively larger enclosed air volume. When they are shifted to their collapsed configurations relatively smaller enclosed air volumes.

Abstract: A speaker mounting system comprising a speaker housing configured to house a speaker, a wall mount configured to be mechanically fastened to a wall, and one or more adjustment pieces actuatably connecting the speaker housing to the wall mount. The adjustment pieces may comprise a first adjustment piece fixed to the wall mount and a second adjustment piece slidably and rotatably attached to the first adjustment piece and pivotally attached to the speaker housing. The second adjustment piece may be configured to laterally slide toward and away from the wall mount and to rotate about a first axis and the speaker housing may be configured to rotate or pivot relative to the second adjustment piece about a second axis perpendicular to the first axis. The speaker mounting system may also comprise a biasing member and locking mechanism for selectively allowing and preventing rotation about the first and second axes.

Abstract: An audio speaker system employs an annular gasket that separates the sound reproducing membrane of a speaker driver with a horn waveguide. The annular gasket is disposed in an area outside of and adjacent to the throat of the horn waveguide. The annular gasket is preferably realized from closed cell foam or other compliant acoustically-absorbable material. The gasket minimizes the volume of the compression chamber that the sound reproducing membrane is compressing, thus leading to less frequency cancellation (which leads to improved frequency response of the speaker driver).

Abstract: A speaker system includes a speaker driver loaded by a horn waveguide. The speaker driver reproduces sound within an extended frequency range that includes a high frequency band between 8 kHz and 11 kHz. In the preferred embodiment, the extended frequency range includes a wide frequency band between 2 kHz and 11 kHz (and most preferably including the frequency band between 800 Hz and 11 kHz). The horn waveguide has an axi-symmetrical waveguide surface that provides uniform polar dispersion at dispersion angles greater than 90 degrees for sound within the extended frequency range. The waveguide surface preferably has an annular cross section with a radial dimension that increases curvilinearly from its throat to its mouth, such as a tractroid surface.

Abstract: Eyeglasses comprises a face and temple. The face has an outer surface including an outer edge. The face also has a first end portion and a first lens opening. The outer edge being proximate to the first end portion. The temple has a portion defining an inner surface. The temple is pivotably coupled to the first end portion of the face. The temple is movable between a folded configuration and an unfolded configuration so that the inner surface of the temple portion can move over the outer edge of the face without obstruction.

Abstract: The present invention is directed towards a method of producing a cereal product or food particulate with zero net glycemic carbohydrates. In one aspect, the product or particulate has a defined cell structure and cell strength. In another aspect, the method comprises preparing, cooking, expanding, cutting and drying a protein blend.
