Abstract: Melody and accompaniment audio signals are received and processed to identify one or more harmony notes and a harmony signal is produced based on the one or more harmony notes. Typically the melody note is identified and a spectrum of the accompaniment audio signal and is obtained, and one or more harmony notes are identified based on the melody note and the accompaniment spectrum. The melody, and accompaniment signals can be processed in real-time for combination with the harmony signal in an audio performance. In some examples, audio signals are processed and harmonies generated for subsequent performance based on, for example, MIDI files generated from the audio signals.

Abstract: A guitar delay engine such as a multi-tap delay pedal or other rhythm engine such as a vocal multi-tap delay pedal, a drum machine, or any other device that requires setting a rhythmic pattern (i.e. level and timing information) for operation is provided. In a guitar delay device, the guitarist can hold down a foot pedal, play a rhythmic pattern on their guitar, and then release the foot pedal and have the rhythmic pattern just played emulated in the delay pattern on the device.

Abstract: Fencing system including elongate posts adapted to be secured to the ground, fence sections each arranged between an adjacent pair of posts and including downward-facing mounting pins, and post clips arranged on the posts. Each post clip includes a tubular mounting collar slidable along and rotatable relative to the posts, a locking mechanism for locking the mounting collar in a fixed vertical position and a pin-receiving ring defining an aperture for receiving one of the mounting pins to enable engagement of the mounting pins with the post clips and thus engagement of the fence sections with the posts. Assembly of the fencing system includes positioning the post clips on the posts, securing the posts to the ground, and placing the mounting pins through the pin-receiving rings of the post clips once the posts are secured to the ground and the post clips are set at the desired vertical location.

Abstract: A water purification system and method for residential or commercial application having a first support structure coupled to a water supply having a first heat source of sufficient magnitude to change the water into steam, thus abandoning any insoluble material dispersed within the liquid. The steam is further heated in a second support structure to form a substantially gaseous vapor and exposed to a second heat source of sufficient magnitude to super-heat the vapor to a temperature capable of destroying most, if not all living matter. Preferably, the second heat source is an electrical field of sufficient voltage to increase the temperature of the vapor in excess of 2000° F. The super-heated vapor is then allowed to condense to form potable water. This system may be powered by a standard 120 volt outlet found in the home.

Abstract: A grease gun includes a tubular casing having a first end, a second end, and an interior cavity defined by interior sidewalls. A pump mechanism is positioned at the first end of the casing. A piston is disposed in the interior cavity in sliding contact with the interior sidewalls. A shaft is provided having a first end secured to the piston and a second end that extends past the second end of the casing. A ratchet mechanism is positioned at the second end of the casing which engages and imparts axial movement to the shaft to move the piston toward the first end of the casing. The ratchet mechanism applies sufficient pressure to force entrapped air from the grease gun.

Abstract: A high-speed correlator includes a serial-to-parallel convertor, and a pattern detector. The serial-to-parallel converter converts from ECL to TTL logic. The pattern detector includes a fast latch data pipe, high-speed RAMs and a fast adder. The data pipe applies the received data to the high-speed RAMs as address bits. Depending upon position and errors in the synchronization pattern various locations in the RAM are addressed. By preloading the RAM with appropriate data for a given synchronization pattern, position and error information is read from the addressed location and applied to correlate the data and determine the error content.

Abstract: In a semiconductor polycide resistive element having a first region of polysilicon of one conductivity type and second regions of polysilicon of opposite conductivity type, with silicide overlying the polysilicon but not the first region, the edges of the silicide are spaced apart from the boundaries between the opposite conductivity types.

Abstract: A wear rod for skis of snowmobiles and similar vehicles, comprising a horizontal base for engaging an underside of a ski and a vertical wear element projecting downwardly from the horizontal base. The base provides firm support for the wear element and good protection for the ski against bending, whereas the wear element provides good penetration into the snow and good steering control. By making the wear element shorter than the base in the longitudinal direction of the ski, the ratio of the length of the wear element in front of the pivoting point of the ski to the ratio of the length behind this point can be varied to provide favorable steering control characteristics without affecting the support for the ski.

Abstract: The present invention relates to a heating device for submersion within a tank of water to boil the water to produce steam, and for superheating the steam, comprising an outer sleeve; an inner sleeve partially disposed through the outer sleeve and having a proximal end, and a distal end in the form of an outlet port, the inner sleeve further defining a vapor chamber; a heating element disposed within the vapor chamber and in electrical communication with an external electrical power supply, the heating element adapted to produce heat in response to electrical energy from the power supply; a steam inlet tube extending outwardly from the inner tube and in fluid communication with the vapor chamber; and a one way valve disposed within the vapor chamber adjacent the outlet port, the valve adapted to selectively gate the flow of vapor from within the vapor chamber through the outlet port; wherein the heating device is configured to heat the water within the tank to a boil to produce steam, the steam inlet tube ada

Abstract: Steering skis for snowmobiles and similar vehicles. The ski has a lower surface for contacting the snow and at least one upwardly curved lateral edge in a region of the ski used for support of the vehicle. The curved lateral edge defines a convex curved snow-engaging surface which merges smoothly with the lower surface of the ski. The curved edge generates lift during turning of the ski while minimizing drag characteristics of the ski. The ski is less likely to result in tipping during turns at high speed in deep snow, which improves the safety of the vehicle. The curved edge produces minimal drag while turning and this allows for more use of the lift generated by the ski.
