摘要： A position control system for controlling a motor-driven mechanism capable of occupying a plurality of specified positions comprises a plurality of switches for specifying a position to be occupied by the mechanism and an encoder for generating a specified position signal representative of the specified position and a loading circuit for providing a present position signal representative of the position presently occupied by the mechanism. A read-only memory circuit uses the specified and present position signals to provide a control signal for controlling the motor to move the mechanism to a particular position and a comparison signal and a particular position signal indicative of that particular position. A position detector responsive to the position of the mechanism provides a detection signal representative of the particular position when the mechanism reaches it. A comparator compares the comparison signal from the memory circuit with the detection signal and provides a match signal to the loading circuit when they coincide. In response to the match signal the loading circuit loads the particular position signal into the memory circuit as the present position signal. If the particular position signal matches the specified position signal, the memory circuit provides a control signal that stops the motor. If the particular position does not match the specified position signal, the memory circuit provides a control signal to actuate the motor again. The illustrated embodiment of the system provides a tape recording and reproducing apparatus with four different operating modes.

摘要： A tape recorder has an operating mode in which a magnetic tape is run at a speed higher than an ordinary reproducing speed, a magnetic head is in sliding contact with the magnetic tape, and a desired tape position is searched. In this operating mode, the magnetic tape is run initially at a first speed higher than the ordinary reproducing speed, for example triple that speed, for a predetermined period of time after an operating switch that sets the operating mode is turned on. Then, if the operating switch remains continuously turned on after the elapse of this predetermined period of time, the magnetic tape is run at a second speed which is higher than the first speed, for example 16 times the ordinary reproducing speed. In this manner, the tape speed is automatically switched from a high-speed and therefore efficient search mode in which a selected section of the tape is searched to a still higher speed in which the tape is rapidly advanced to a different section of the tape.

摘要： A digital recording and playback system with built-in voice recognition capability for concurrent text generation. In one embodiment, the system comprises an audio capturing device configured to receive a voice input. The system also comprises a high compression encoder (HCE) coupled to the audio capturing device and configured to generate digital wave data corresponding to the voice input, as well as a voice recognition engine (VRE) coupled to the audio capturing device and configured to generate text data corresponding to the voice input. In this embodiment, the HCE and VRE are selectively coupled to a memory sub-system which is configured to store the digital wave data and the text data. In this embodiment, the VRE performs voice-to-text conversion using the high quality audio input signal rather than highly compressed voice data so that high quality conversion is achieved. In this embodiment, the HCE and the VRE are operable to concurrently generate the digital wave data and the text data in response to the voice input such that the digital wave data and the text data can be stored in the memory sub-system in a synchronized manner. As such, this embodiment of the present invention provides recording capability wherein text data is generated from a voice input without requiring post-recording conversion. In a specific embodiment, the present invention includes the above and wherein the system is battery-powered and is portable.

摘要： A receiver is provided for an information system that provides selected information to individual users. A high speed digital program signal is broadcast and contains program data that begins at a reference time and is repeated at set intervals. An index signal that contains the receiver's identifier associated with the reference time and interval information is also broadcast. The receiver monitors the index signal for its identifier. When the receiver detects its identifier, the receiver downloads the time and tuning information. The receiver then uses the time and tuning information to receive, download, and store the user's selected program. In some embodiments a transceiver replaces the receiver to allow the user to make remote program requests.

摘要： A device for recording a motion picture film and a device for projecting a motion picture film susceptible to generation of low noise due to film feed are provided. A motion picture film 10 is fed on the frame basis so that the film is fed as it is clamped between an idler 45 and a rotary drum 48 and so that the film feed is stopped as a voice coil 43 is driven for displacing the idler 45 away from the rotary drum 48. A recording unit 30 records a frame image of the motion picture film each time the film feed is halted. Recording may be made in this manner under the state of extremely low noise level due to film feed. Film feed is made in a similar manner during projection of each frame image, and each frame image is also projected by a projection unit 70 each time the film feed is halted. Projection may also be made in this manner under the state of extremely low noise level due to film feed.
