Abstract: A contact sensor assembly includes a sensor comprising a plurality of sensing areas, a plurality of non-sensing areas, and a connector coupled to the plurality of sensing areas. The contact sensor assembly also include an outer cover positioned over the sensor. The outer cover has an inner surface and an outer surface. The inner surface includes a plurality of raised portions and at least one corner section. The at least one corner section of the inner surface of the outer cover is reinforced so that the corner section has a greater stiffness and the corner section corresponds to at least one non-sensing area of the sensor.

Abstract: A hybrid whistle has two pealess whistle chambers with air vents to the left and right and a central pea whistle with an air vent facing generally perpendicularly to the left and right air vents that are integrally formed together, preferably in a two piece, top and bottom, construction. The hybrid whistle has a mouthpiece with a left air opening, a central air opening and a right air opening, each of which is connected to its respective whistle chamber by an air passageway. The three whistle chambers produce differing whistle pitch sounds as air flows through them and out the chambers' exits. The central pea whistle has a barrel chamber with a pea block formed within it so as to modify the barrel shape of the chamber and block the air flow as the pea circulates in the air current causing a staccato effect, while creating enough circulating air movement to prevent the pea from getting stuck in the vent by the air as it exits out of the central air exit when the whistle is blown.

Abstract: A music system including a musical instrument, such as a keyboard strummer, in which the musical notes produced by the playing of the instrument are controlled by musical assistance data mapped unto the instrument keys and strum vanes from tracks specially prepared and synchronized with a prior performance of the piece. Modified mass media, such as CD ROM, TV signals and video cassettes are provided including synchronized note assist data and additional media, such as ROM packs or tone encoded audio cassettes or CDs, are provided with synchronizable note assist data for use with unmodified mass media.
