Abstract: A sound generation apparatus for an electric vehicle that is being operated by a driver comprising: a sound generation circuit attached to a wheel of the electric vehicle; Faraday generators for supplying pulses of electrical current within the circuit while the wheels of the vehicle are rotating; a battery for supplying battery power within the circuit; a pulse activated power controller that is activated upon the receipt of an initial pulse form one of the Faraday generators and controls the supply of battery power within the circuit; and a programmed microcontroller that uses the battery power to simulate a motor sound for the electric vehicle and uses additional pulses from the Faraday generators to determine whether the vehicle is accelerating, decelerating or moving in reverse and, based upon its state of motion, modifies the simulated motor sound.

Abstract: A method of using an injection mold assembly to fabricate a bulkhead fitting. The method includes using a core plate, aperture plate and a pair of slide blocks to form the mold assembly which contains the mold cavity. The aperture plate, which has an opening through the plate, is positioned within the assembly such that the fitting, which is molded within the mold cavity, does not contain a parting line across the sealing surface and o-ring groove of the fitting.

Abstract: A database management and synchronization program implemented across a peer-to-peer computer network, consisting of a sharing community of user computers. Database record synchronization throughout the sharing community is accomplished by using a synchronization object which contains the information about a change in a specific record or the addition of a new record. The synchronization object is transmitted by a local user computer at any time to a routing agent, which in turn transmits the synchronization object at any time to remote user computers within the sharing community. The synchronization object is then used by the remote user computer to update their database records.

Abstract: A pill loader system comprising a pillbox loader and a matching pillbox for loading pills into the pillbox. The pillbox loader has a plurality of loader containers, and the pillbox has an identical number of pillbox containers. The pillbox loader is positioned on top of the pillbox and the pills are placed into the loader containers according to instructions written on a pillbox loader form, which is positioned within a loader bottom plate which is slidably inserted between the loader and pillbox such that the loading instructions appear in the bottom of the loader containers. In operation, the loader bottom plate is removed, and the pills drop into corresponding pillbox containers.

Abstract: The present invention generally includes a submersible marine vehicle for recreational use in which a propeller and motor assembly is disposed within the vehicle's hull and a battery is disposed beneath the hull. The front end of the hull contains a plurality of inlets and the back end contains a plurality of outlets. The propeller and motor assembly is disposed within the hull such the propeller is adjacent to the hull's front end and the motor is adjacent to the hull's back end. Each propeller blade has its leading edge aft of its trailing edge. The hull includes a pair of fins which are integral with the hull, each fin extending horizontally and away from the hull. Each fin contains a hand hold, extending downwardly and away from the underside surface of the fin. A pair of curved tracking fins are attached to opposite sides of the bottom side of the hull, each curved tracking fin extending outwardly and downwardly away from the hull.

Abstract: A grinding machine turret enclosure system and an integrated computer monitor. The turret system comprises a pair of curved turret doors which are disposed between a circular top enclosure and a circular bottom turret platform. Each turret door forms a circular arc of approximately 130°, and each door is slideably positioned within a respective circular channel. Access to a grinding machine staging area is provided by sliding one or both doors in a circular direction, within its channel, away from the other door. When both doors are fully opened, access of approximately 230° is created around the staging area. A computer monitor, which is used to set grinding coordinates, is pivotally attached to the top of the circular enclosure such that a grinding operator may revolve the monitor around the staging area to the area where adjustments are being made.

Abstract: Polyvinyl alcohol and related compounds are provided that inhibit the freezing of water and water solutions. These synthetic compounds preferentially bind and inhibit ice nucleating surfaces in a manner similar to natural antifreeze proteins. The resulting inhibition allows water and water solutions to supercool without ice formation to temperatures below the thermodynamic freezing point. The freezing inhibition occurs at concentrations as small as one part per million, although concentrations up to one part per hundred are preferred. These polyvinyl alcohol additives are very useful for enhancing the performance of antifreeze formulations, biological cryopreservation solutions, and for preventing frost damage to plants and other industrial products and processes.

Abstract: The optical sensor of the present invention detects both the existence and concentration of substances by changing from light leakage mode to wave guide mode when the sensor is exposed to the substances to be detected. The changes in the mode results in a large change in optical output. This change is measured and the substance is identified and/or measured with high sensitivity. The change in light leakage mode to wave guide mode of the sensor is possible by having a clad material around the core material, with the clad material decreasing in the index of refraction when exposed to the substance to be detected. When the index of refraction of the clad becomes less than that of the core material, the sensor changes from the light leakage mode and operates in the wave guide mode. Changes in light intensity output from the sensor is measured over time, and correlated to the substance to be detected.

Abstract: An expandable sleeping bag comprising a modified draft tube design incorporating a draft tube expansion segment and expansion zipper which are used to expand the circumferential measurement of the sleeping bag's inner lining and outer shell.

Abstract: A gaiter having on its outside surface an air vent system which allows a user to vent the gaiter in order to permit air to pass through the side of the gaiter, and having on an opposite outside surface a coated fabric protective surface which has a coated fabric surface top seam which is slanted in a downward direction from the back of the gaiter to the front.

Abstract: An ergonomic armrest primarily for use by dentists or dental hygienists permitting them to rest their arm on an armrest platter and to simultaneously rotate and revolve the platter so that they can perform an operation on a patient's teeth, while continuing to rest their arm. The bottom surface of the armrest platter is pivotally connected to the unsupported end of a cantilevered member, which is pivotally connected at its supported end to a rigid, but height adjustable, vertical support assembly.
