Abstract: This invention provides a system for customizing musical instrument signal processing enabling users to produce different tonal characteristics in created musical pieces. In order to create such tonal characteristics, a new mathematical model of tonal characteristics may be digitally created based on two or more initial mathematical models of tonal characteristics. After simulating a first and second initial mathematical models of tonal characteristics, the new mathematical model is created by interpolating one or more coefficients of the first and second initial mathematical models. The new mathematical model may also adjust a control parameter where the control parameter may exist between two values. When the control parameter is the first value, the new mathematical model is the first initial mathematical model. When the control parameter is the second value, the new mathematical model may be the second initial mathematical model.

Abstract: A device for preventing the rotation of a power drill attachment relative to a power drill is provided and is described in combination with a liquid sprayer. The device having a container (10) with a supply tube (12) extending downward into the container (10) and upward into a pump inlet (14) which is open to a pump (16.) The pump (16) has on the rearward side a pump seal (18) and a pump drive (20) and on the forward side a pump outlet (22) and nozzle (24). The pump has a rod (26) affixed to it by means of a rod attachment (28). The rod (26) extends rearward and includes an ergonomic rod pillow (30). Also included is a power drill (36) including a power drill trigger (32) and a power drill chuck (34). When energized the power drill (36) imparts rotational energy to the pump (16). Rotation of the pump (16) relative to the power drill (36) is prevented by the communication of the rod (26) the rod attachment (28) and the housing of the power drill (36).

Abstract: An improved liquid sprayer having a container (12) with a handle (14). A supply tube (16) extends into the container (12) and upward through a container cap (18) and a container cap attachment (20) and into a pump inlet (22) which is open to a pump (24). Adjacent to the front of pump (24) is a pump outlet (26) and a nozzle (27). Adjacent to the rear of pump (24) is a pump drive (32) which removably communicates with a pump drive socket (34) affixed to a conventional rechargeable drill (36). The drill sprayer (10) can be removably attached to the container (12) which then is refilled and reused. Alternately, the drill sprayer (10) can be permanently affixed to the container (12) and therefore disposable.

Abstract: An on-board diagnostic system for an evaporative emission control system of an internal combustion engine powered vehicle employs a positive displacement reciprocating pump to create in evaporative emission space a pressure that differs significantly from ambient atmospheric pressure. The pump is powered by using engine intake manifold vacuum to force an intake stroke during which both an internal spring is increasingly compressed and a charge of ambient atmospheric air is created in an air pumping chamber space. Vacuum is then removed, and the spring relaxes to force a compression stroke wherein a portion of the air charge is forced into the evaporative emission space. The rate at which the pump reciprocates to alternately execute intake and compression strokes indicates the pressure and flow through a leak in the evaporative emission space. Detection of this rate serves as a measurement of leakage for the purpose of distinguishing integrity of the evaporative emission space from non-integrity.

Abstract: An assembly convertible between a raised house ID display sign configuration and a lowered support shelf configuration includes a lower base plate stationarily attached on a wall portion of a house adjacent to an entry door, an upper face plate mounting ID indicia to identify the house, and a plurality of hinges attached respectively between the lower base plate and upper face member to enable pivoting of the upper face plate relative to the lower base plate between the raised and lowered configurations. The assembly also includes an electrical light mounted at a side edge portion of the lower base plate to provide illumination to an area of the entry door adjacent thereto. The light is switched on and off by a button mounted on the lower base plate being respectively engaged and disengaged by the upper face plate when the assembly is correspondingly converted between the support shelf and ID display sign configurations.

Abstract: The canister's inlet port is communicated to the fuel tank headspace through a first conduit, its outlet port is communicated through a second conduit containing the purge control valve to a location in the air intake system that is downstream of the throttle plate, and its atmospheric vent port is communicated through a third conduit to a location in the air intake system that is between the air filter and the supercharger, rather than directly to atmosphere. During non-supercharged operation of the engine, vapors in the canister are purged through the second conduit and purge control valve in the usual manner and air enters the canister through the third conduit. During supercharged operation, the purge flow is reversed such that purged vapors pass through the third conduit while the purge valve maintains control over the purge flow.

Abstract: A vacuum check valve comprising a single umbrella valve responding to vacuum differences between the input and output of the check valve. The check valve directs the output line to feed a vacuum operated device with either the vacuum source or reference air through a bleed passage. The umbrella shaped valve eliminates the requirement for a diaphragm operated poppet valve.
