Patent number: 6865619Abstract: A method for controlling the status of a drive of an apparatus for reading from and/or writing to recording media is proposed. According to the method, a plurality of drive states are reported to a controller of the apparatus by applying drive state signals to an interface. To ensure that no drive state remains unnoticed by the controller, the drive state signals are applied to the interface for at least a predetermined period of time, even if one or more drive state actually lasts for a shorter period of time. To guarantee that the drive state reported to the controller is identical to the real state of the drive, one or more of the drive states, which last shorter than the predetermined period of time are artificially extended.Type: GrantFiled: November 1, 2002Date of Patent: March 8, 2005Assignee: Thomson Licensing S.

Patent number: 6094319Abstract: It is known in the case of digital helical track recording and replay apparatuses for audio, video and general data to be recorded for pilot tones to be interleaved in the data tracks, for tracking. The interleaving can be carried out simultaneously with the data by frequency decoupling (a) or by superimposition (b). The invention is based on the object of providing a helical track recording and replay system which carries out tracking in a simple manner. According to the invention, the ATF signal is obtained in a filter module, which also carries out the rectification of the filtered-out pilot tones. The two DC voltage levels are interrogated and processed in the servo microcontroller, with A/D converters. Coupled to the rotation of the head drum, pulses are produced by the servo system which switch the ATF conditioning over between direct operation and tracking operation, so that evaluation is achieved by the microcontroller during the fast ATF burst phase.Type: GrantFiled: December 11, 1997Date of Patent: July 25, 2000Assignee: Deutsche Thomson-Brandt GmbHInventors: Dietmar Braeuer, Juergen Kaaden, Gerhard Reiner

Patent number: 5912543Abstract: Electronic circuit having a digital controller operation of a synchronous motor.Precision motors for driving, for example, a video head drum in video recorders are normally designed as externally commutated synchronous motors. These motors are driven with square-wave voltages by a digital controller (CON), whose circuitry can easily be implemented.The object of the present invention is to specify an electronic circuit of the type mentioned initially for controlling a synchronous motor, which enables good synchronism and the motor to be operated with little electrical noise.This object is achieved in that the synchronous motor is driven by sinusoidal signals, a separate control signal from the controller (CON) influencing the amplitudes of the drive signals (U1, V1, W1). A regulating signal for regulating the synchronous motor is produced by a sensor (GE) which is arranged on the synchronous motor, which regulating signal produces a fixed phase relationship between rotor revolution and drive signals.Type: GrantFiled: October 18, 1996Date of Patent: June 15, 1999Assignee: Deutsche Thomson-Brandt GmbHInventors: Peter Mahr, Gerhard Reiner

Patent number: 5911034Abstract: In order to produce synchronous control signals of a video recorder, in particular of a digital video recorder, a position pulse of the scanner motor, which coincides with the beginning of the video frame, is used as time zero point. Time markers in which changes in the control signals take place are calculated starting from this time zero point. These time markers and the bit patterns occurring at these time markers are stored as data words in a data field and, for corresponding time markers, the corresponding data word is output in parallel, that is to say synchronously. A realization is possible by means of a microcontroller and a controllable output memory, the microcontroller containing the functions of capture register, timer, calculation unit and comparator.Type: GrantFiled: October 9, 1996Date of Patent: June 8, 1999Assignee: Deutsche Thomson-Brandt GmbHInventors: Peter Mahr, Gerhard Reiner

Patent number: 5486727Abstract: A linear accelerator has at least one longitudinal stator section that defines a linear path of movement and that comprises several stator coils as well as a rotor with several rotor coils that can be accelerated along the path of movement. The stator is designed as a tubular body from the inner wall of which project coil carriers with coil conductors that are mutually offset by 90 degrees. The cavities thus formed are engaged by the rotor coils that comprise each an electrically non-conductive carrier on the sides on which are arranged meandering coil conductors. The design and arrangement of the rotor coils and stator coils allow a circular magnetic field to be generated, with the result that the rotor is axially accelerated. The rotor is supplied with current by conductor rails by a cable entrained with the rotor an/or by charge accumulation in the coils before acceleration begins.Type: GrantFiled: January 6, 1994Date of Patent: January 23, 1996Assignee: Magnet-Motor Gesellschaft mbHInventors: Gotz Heidelberg, Peter Ehrhart, Gerhard Reiner, Andreas Grundl

Patent number: 5471124Abstract: The determination of the position of a tape thread-in and thread-out mechanism in a cassette recorder is carried out using contact paths together with a slider contact that form position switches. Output signals of the position switches are coupled via a resistor network that combines the output signals and produces an output signal on a single conductor. The resistor network output signal is coupled to an input of an analog -to-digital converter. To improve the reliability of determining the position of the mechanism without requiring the use of highly accurate resistors in the resistor network, the voltage value assigned to each individual position is measured at the output of the network during a calibration operation. The voltage values are stored in a memory and used as the desired values during normal operation.Type: GrantFiled: June 23, 1994Date of Patent: November 28, 1995Assignee: Deutsche Thomson-Brandt GmbHInventors: Jurgen Kaaden, Gerhard Reiner
