    摘要: A piano includes a plurality of keys having forward and rearward ends and an emitter and a detector both disposed adjacent the rearward end of each key. The emitter emits a signal directed toward a surface of the rearward end of the key. The detector receives a signal reflected from the surface of the rearward end of the key. A controller is in communication with the emitter and the detector and processes detection signals received from the detector to determine key movement.

    摘要: A piano, playable in an acoustic mode and a silent mode, includes a series of keys, a series of key actions, and a series of rotatable hammers. Each key action is actuated by depression of a corresponding key. Each hammer defines a forward throw direction and has a corresponding string. The hammers are driven by corresponding key actions transferring forces from corresponding keys. The piano includes a hammer stopper system that has a blocking rail slidably disposed forward of the hammers. A linear actuator moves the blocking rail along a substantially linear path between a first position, allowing unobstructed movement of the hammers, and a second position blocking at least one hammer from striking its corresponding string. The linear actuator moves the blocking rail to the first position for acoustic play and to the second position for silent play.

    摘要: A piano hammer stopper system includes a blocking rail movable between a first position, allowing unobstructed movement of piano hammers, and a second position, blocking at least one piano hammer from striking any corresponding strings. The piano hammer stopper system includes a drive shaft rotatably coupled to the blocking rail, a drive arm attached to the drive shaft and engaging a drive fulcrum, and a travel guide directing movement of the blocking rail between its first and second positions. Rotation of the drive shaft rotates the drive arm to engage the drive fulcrum for moving the blocking rail between its first and second positions.

    摘要: A piano hammer stopper system includes a stopper rail set comprising at least first and second stopper rail members, each movable between respective first positions allowing unobstructed movement of associated piano hammers and respective second positions stopping at least one associated piano hammer from striking any corresponding string. At least one drive shaft is rotatably coupled to one or both of the stopper rail members. A drive arm is attached to the drive shaft and engages a drive fulcrum. A travel guide directs movement of the first and second stopper rail members between respective first and second positions. Rotation of the drive shaft rotates the drive arm to engage the drive fulcrum for moving one or both of the first and second stopper rail members between respective first and second positions.

    摘要: A spinal fixation device for securing to a spine includes a body having one or more longitudinal members extending between a pair of wedge members. Each wedge member defines one or more openings therethrough for the reception of a bone screw. The wedge members are disposed on opposite ends of the one or more longitudinal members. One of the wedge members is positionable within a first intervertebral space and the other wedge member is positionable within a second intervertebral space. The one or more longitudinal members define a length that spans one or more vertebrae. The one or more longitudinal members are positionable within the one or more vertebrae when the wedge members are positioned within the respective first and second intervertebral spaces to maintain the body in a minimal profile orientation relative to the spine.
