Abstract: A computerized tablature composer automatically updates a tablature notation following edits of a corresponding staff notation. The computerized tablature composer conversely links edits to a tablature notation with corresponding updates in a staff notation for a corresponding musical score. The computerized tablature composer ensures vertical alignment between corresponding notes in a staff notation and a tablature notation. The computerized tablature composer ensures that the actual played notes in both musical representations are aligned so that the musician knows which note in the staff notation corresponds to which note in the tablature notation. The computerized tablature composer further allows the coupling between tablature and conventional staff notation to be de-coupled upon request. The computerized tablature composer provides a musician with alternate fret locations for the notes in a musical work when the musician indicates an alternate string for a given note.

Abstract: A method and system for training a handwriting recognizer at the time of misrecognition is provided. In a preferred embodiment, a trainer program traps and stores the output from a recognizer. The output includes the recognized symbols mapped to the handwritten data. When training is requested by a user, the trainer displays the handwritten data that was input by the user and the recognized symbols. The user then selects the symbols to train on. In response to the selection, the trainer displays the portion of the handwritten data corresponding to the selected symbols. The user then enters the symbols that the displayed portion of the handwritten data should be recognized as. The trainer then requests the recognizer to train based on the displayed portion of the data and the entered symbols. When training is complete, the trainer requests re-recognition of the handwritten data and displays the newly recognized symbols.

Abstract: A method and system for recognizing a graphic object's shape, line style, and fill pattern in a pen environment are provided. In a preferred embodiment, a user draws a graphic object on an electronic tablet of a computer system. The graphic object comprises a shape attribute, a line style attribute, and a fill pattern attribute. A Recognizer, recognizes the graphic object. The graphic object is made up of a plurality of data points, each data point having an x-coordinate and a y-coordinate. The Recognizer subdivides the plurality of data points into one or more strokes, each stroke representative of a path travelled by the handwriting instrument after the handwriting instrument touches the tablet and before the handwriting instrument is lifted off of the tablet.

Abstract: The present hydraulic system for driving a submersible pumping unit has an above-ground pump for pumping oil through a hydraulic motor in the submersible pumping unit, and a check valve between the above-ground pump and that hydraulic motor to prevent the reverse flow of oil after the submersible pumping unit is turned off. A pressure regulating valve limits the oil pressure to the hydraulic motor. The inlet flow to the above-ground pump is filtered.

Abstract: In a pumping installation having an above-ground prime mover driving an axial-flow pump below through a relatively long drive shaft unit, the drive shaft unit is coupled to the pump shaft through a sliding coupling which accommodates axial expansion and contraction of the relatively long drive shaft unit due to temperature changes. The pump shaft is provided with combined rotational and axial thrust bearings for taking up axial thrusts in either direction, and an improved shaft seal is provided for the pump shaft.

Abstract: The present apparatus includes a mobile cart which supports a winch at one end and a pulley at the opposite end for operating a cable to raise and lower a submersible pumping unit. The submersible pumping unit comprises a rigid discharge pipe supported from below near one end by a pipe support on a slide on the cart. The slide has a horizontal transverse pivot which enables the pipe support to accomodate the tilting of the discharge pipe as its opposite intake end is lowered or raised. The cart carries an engine driving a pump which operates a hydraulic motor for the winch. A basket on the cart holds a flexible discharge hose for attachment to the discharge end of the discharge pipe. The engine-driven pump on the cart is connected through hydraulic lines to a hydraulic motor in the submersible pumping unit, which motor drives a pump inside the discharge pipe near its intake end.
