Abstract: A musical device that includes a housing with a flat top over which a band slides, in both directions, and co-acts with a sensor assembly to detect perforations on the band having predetermined lengths. An electronic simulated musical instrument assembly with inputs adapted to detect each of the sensed coded elements outputs to generate a note or sound for one or more electronically simulated instruments that in turn are amplified and connected to speaker output assemblies. Two or more instruments can play simultaneously and the melody accompaniment, base and percussion performed by the instruments can be changed at any time. A method for playing notes backward without distortion.

Abstract: A recording medium, method and apparatus for managing data are discussed. According to an embodiment, the present invention provides a method of reproducing main data and additional data. The method includes receiving the additional data associated with the main data, the additional data being divided into a plurality of segment units; and reproducing the additional data in a synchronous manner with the main data using time information if indication information indicates a presence of the time information. The time information indicates a presentation time of the additional data with respect to the main data. The main data and the additional data are reproduced according to management data, the management data including link information for linking the main data and the additional data.

Abstract: A recording medium and a method and apparatus for managing data are provided. The method includes recording additional data in a data file separate from a file containing main data and recording navigation information that links the main data and the additional data. The additional data are segmented into a plurality of predetermined units, each of the predetermined units including time information indicating a presentation start time of the corresponding unit.

Abstract: A method for modifying an audio visual recording originally produced with an original audio track of an original speaker, using a second audio dub track of a second speaker, comprising analyzing the original audio track to convert it into a continuous time coded facial and acoustic symbol stream to identify corresponding visual facial motions of the original speaker to create continuous data sets of facial motion corresponding to speech utterance states and transformations, storing these continuous data sets in a database, analyzing the second audio dub track to convert it to a continuous tune coded facial and acoustic symbol stream, using the second audio dub track's continuous time coded facial and acoustic symbol stream to animate the original speaker's face, synchronized to the second audio dub track to create natural continuous facial speech expression by the original speaker of the second dub audio track.

Abstract: Apparatus is provided for producing simultaneous visual and audio signals for synchronizing separate simultaneously produced visual and sound recordings, e.g., for use when making cinematographic or video recordings and separate sound track recording. The apparatus comprises means such as a keyboard for entering and storing a selected sequence of alpha/numeric characters, means such as a liquid crystal display for visually displaying an entered and stored sequence of alpha/numeric characters, speech synthesizer means for audibly sounding the entered and stored sequence of alpha/numeric characters, and means for simultaneously providing visual and audible start marks for synchronization.

Abstract: A nonvolatile semiconductor memory device having floating gate type field effect transistors with floating gate electrodes. In the memory device, a source region, an active region and a drain region are formed in a first semiconductor region. A second semiconductor region is formed so as to electrically be insulated from the first semiconductor region. A floating gate electrode is formed on the first and second semiconductor regions with an insulating film interposed therebetween, respectively. The floating gate electrode faces the second semiconductor region with the insulating film interposed therebetween so that charge may be transferred between the floating gate electrode and second semiconductor region in order to control an amount of charge in the floating gate electrode.

Abstract: Two or more motor driven systems are maintained in synchronism by a recorded wave of sine form on a tape driven by one of said systems, a signal derived from said sine wave being used to drive a stepper motor or stepper motors included in the other system or systems. The invention is particularly applicable to the synchronization of a film passing through a camera or projector with a sound track recorded on a magnetic tape, or of a number of films passing through a plurality of projectors or cameras. By converting the sine wave to pulses and maintaining a count of the pulses, (a) derived from the control signal and (b) supplied to the stepper motor, synchronism is maintained despite inertia effects during repeated starting, stopping and reversal of the drive.

Abstract: A portable slating device comprises a light-tight housing having a lens on the front thereof and a copyholder on the rear thereof. When the lens on the front end of the housing is positioned adjacent the lens of a movie camera whose scene takes are to be identified by slating information, the housing lens functions as a supplementary close-up lens cooperating with the camera lens to sharply focus the information in the copyholder onto the film in the movie camera. When the filming of a scene-take starts, the operator closes a switch for simultaneously energizing a synchronizing light bulb located within the housing and an audio signal device mounted on the housing to provide for synchronizing the visual action of the film with the sound track.

Abstract: In a movie camera a control frequency generator for producing a picture and sound synchronizing sinusoidal control frequency using a rotating member of the camera such as a running gear made from a soft magnetic material and having a magnetically discontinuous region formed therein, a permanent magnet having one pole thereof placed in the vicinity of the discontinuous region, and a magnetic flux sensing device placed between the region and the pole of the permanent magnet for sensing the flux changes within the magnetic circuit during rotation of the camera gear and thereby producing the synchronizing control frequency.
