Abstract: This development allows Luthiers of fretted instruments an uncompensated method of installing frets with increased accuracy. It is an improvement in calculation of fret placement over the “Rule of 18”, because it relies on the length of the vibrating string. This method is more critical at the end of the fret board closest to the bridge, due to the angle formed by the string when depressed, with respect to the axis of the fret board. With respect to the twelve step octave, the scale length is multiplied by the constant of “the twelfth root of 0.5” to calculate the length of the string from fret contact to saddle contact for the next tonal step.

Abstract: A dual foot pedal system operates on a bass drum with a beat having a different rhythm. The first foot pedal operates on the drum by a direct transmission from the pedal to the surface of the drum. The second foot pedal has a mechanism thereon that changes the relative position of the travel between the cantilevered hammer heads to obtain a difference of a beat on the drum. The difference is achieved by a driven disc which is operated by the second foot pedal stepped upon by the individual drummer. There is a floating disc adjacent to the driven disc adjustably connected to the driven disc which changes the length of time of the second cantilevered hammer head to travel to an impact on the drum relative to the impact obtained by the first foot pedal.

Abstract: A system and methods use music features extracted from music to detect a music mood within a hierarchical mood detection framework. A two-dimensional mood model divides music into four moods which include contentment, depression, exuberance, and anxious/frantic. A mood detection algorithm uses a hierarchical mood detection framework to determine which of the four moods is associated with a music clip based on the extracted features. In a first tier of the hierarchical detection process, the algorithm determines one of two mood groups to which the music clip belongs. In a second tier of the hierarchical detection process, the algorithm then determines which mood from within the selected mood group is the appropriate, exact mood for the music clip. Benefits of the mood detection system include automatic detection of music mood which can be used as music metadata to manage music through music representation and classification.

Abstract: A method and apparatus counteracts the muzzle lift of a firearm resulting from recoil, and a firearm has an integral counteracting structure. A port extends from an inner surface of the firearm barrel bore to an outer surface of the barrel, forward of the location that the propellant ignites, to an occluding structure located beneath the grip surface of the firearm. When the propellant is ignited, and the projectile passes the relief port, a portion of the propellant gas exits the bore prior to the muzzle end, travels through the propellant gas relief tube, and exerts a force on the occluding structure. The force acts downward on the firearm, counteracting the recoil-induced muzzle lift.

Abstract: An airless sprayer for paint or the like consists of an electric drive unit connected to a piston. Driven by the electric drive unit, the piston reciprocates within the cylinder, thus spraying the paint or the like. Because of the close tolerance between the piston and cylinder (typically about 0.0002 to about 0.0003 inches), the sprayed liquid provides a seal between the piston and cylinder. To prevent this tolerance from increasing to the point of failure, the cylinder is manufactured from nitride hardened steel. A process for manufacturing the airless sprayer is also disclosed.

Abstract: Oil system components for a turbine engine are used to provide a vacuum system for a fuel stabilization unit (FSU). A vacuum system pulls oxygen and other contaminants from fuel into a vacuum chamber within the FSU. The vacuum system pumps the discharge through a vacuum outlet in the FSU toward a vacuum pump. Due to the quality of vacuum required, a two-stage vacuum pump is used. A first stage vacuum pump is an oil system scavenge pump for the turbine engine and the second stage vacuum is provided by a second stage vacuum pump. The discharge flows from the vacuum chamber through to the second stage vacuum pump and is then added to the oil supply. The oil and discharge mixture is sent through an oil system de-oiler and a de-aerator to clean the oil supply prior to pumping the oil back through the oil system.

Abstract: A carbon canister to adsorb hydrocarbons from a hydrocarbon air mixture in a UST system to prevent fugitive emissions due to overpressurization. The carbon canister has an inlet port at one end coupled to the UST system. An outlet port on the opposite end of the canister is connected to a flow-limiting orifice with a known calibrated flow rate that vents in a controlled fashion to the atmosphere. When UST pressure rises slightly above ambient pressure, fuel vapors and air from the UST system enters, via the inlet port, into the canister, where hydrocarbons are adsorbed onto the surface of the activated carbon. The cleansed air vents through the controlled flow outlet port to atmosphere, thereby preventing excessive positive pressure from occurring in the UST system. The activated carbon is purged of hydrocarbons by means of reverse air flow caused by negative UST pressures that occur during periods of ORVR vehicle refueling.
