Abstract: The key actuation system is designed for use with a keyboard instrument of the type that has a key fulcrum which pivotally supports multiple keys. Each key has a front end forward of the fulcrum which is to be depressed by a player, and a rear portion which is positioned rearward of the fulcrum and it pivots upwardly when the front end is depressed. The key actuation system includes a pull solenoid with a coil portion and a piston. When the coil portion of the solenoid is energized, the piston is drawn into the coil portion. The solenoid is mounted such that the coil portion is above one of the keys and behind the key fulcrum. The piston is in mechanical communication with the rear portion of the key so that when the coil portion is energized and the piston is drawn into the coil portion, the rear portion of the key is lifted upwardly.

Abstract: A system senses the position of a movable element in a mechanical apparatus. The element moves along an elongated guide member, which is at least partially formed of a magnetic material. An excitation coil is positioned by the guide member and a sensing coil moves with the movable element. An excitation circuit energizes the excitation coil and a position sensing circuit sense a voltage or current in the sensing coil to determine the distance between the coils.

Abstract: A flow control device that creates a pulsating flow includes a body with a flow passage defined therethrough. The device further includes a flow interruption element having a flow interrupting position and an open position and a biasing element that biases the flow interruption element into the flow interrupting position. A flow of gas or fluid passing through the flow passage impinges on the flow-interrupting member causing the flow interrupting member to intermittently move between the flow interrupting position and the open position, thereby intermittently allowing the flow of gas or fluid to pass the flow interrupting element. This creates a pulsating flow of gas or fluid.

Abstract: A key actuation system that is designed for use with a keyboard instrument of the type having multiple keys. Each key is pivotally supported and has a front end that is depressed by a player to play a note. The actuation system includes multiple actuators that are operable to move at least some of the keys. The actuators together include a block of ferromagnetic material with a surface with multiple bores defined in the surface. Each of the bores has a diameter. A winding is positioned in each of the bores. Each of the windings has a hole. A piston is provided at least partially in each of the holes, with each piston being in mechanical communication with one of the keys such that movement of the piston causes movement of the key. Each piston has a width. A ferromagnetic flux plate with multiple openings is positioned on the surface of the block of ferromagnetic material with the openings aligned with the bores. The openings each have a width that is less than the diameter of the bores, such that the flux plate partially closes off the upper end of each bore. When the windings are energized, the corresponding piston moves, thereby moving one of the keys.

Abstract: A pre-fluxing system and method to reduce inrush current for a winding used in a transformer, motor or a solenoid. The system has a primary winding and a tertiary winding connected with a power source for providing electrical energy to these windings. A pre-fluxing circuit is connected to the tertiary winding. The power source provides electrical energy to the tertiary winding via the pre-fluxing circuit, and the pre-fluxing circuit pre-magnetizes the tertiary winding when energized. The tertiary winding is configured to pre-magnetize the primary winding to reduce inrush current when the power source energizes the primary winding.
