Abstract: Telecommunications customers must frequently utilize the facilities of many different telecommunications service providers in order to transmit data from one location to another. When a telecommunications customer encounters a network problem, that customer usually must navigate a complicated web of service providers and equipment owners in order to receive meaningful technical assistance from a human technician. The present invention is designed and intended to facilitate human interactions for technical support and administrative tasks by associating customer, contract, circuit, equipment, key personnel, billing, and telco information in a database for efficient data presentation and information retrieval. Resolution of the logistical problem of tracking circuit information is achieved by organizing the information and displaying important data concurrently.

Abstract: A process and arrangement for tracking and eliminating disturbances which occur in particular while scanning optical information carriers. The invention avoids the inconvenience of disturbance elimination using time-delayed auxiliary beam signals by influencing the auxiliary beams of a scanner working according to a three-beam principle in such a way that they hit the information carrier to be scanned as two auxiliary beams which lie next to each other on the track radius, so that disturbances due to subtraction between the auxiliary light spot signals formed by the auxiliary light spots are eliminated. A birefringent crystal is preferably used in order to direct the auxiliary beams in this manner. The invention is preferably suitable for optical information carrier scanning devices.

Abstract: A disc playback system monitors coded information in the tracks of discs being played back in order to determine the radial position of the information pickup apparatus. Responsive to a disc stop command, the radial position is utilized to determine the angular speed of the disc, and thereby the speed of the motor that is rotating the disc. A time period, necessary for a predetermined signal which accelerates the motor in the reverse direction to stop the rotation of the disc, is calculated in response to the angular speed at the time the stop command is instituted. Thereafter the predetermined reversing signal is applied to the motor for the calculated period to stop the rotation of the disc.

Abstract: A method for recording and reproducing compressed data to improve the utilization of the storage capacity of a moving recording medium. The data are compressed prior to a recording step. Prior to reproduction the data are expanded to retrieve the original data signal. To increase the storage capacity of the recording medium even further, the velocity of the recording medium is regulated as a function of the degree of compression. With a high degree of compression, a smaller velocity of the recording medium is selected, than with a low degree of compression.

Abstract: Apparatus for reproducing coded audio signals includes interpolation circuitry for substituting interpolated signal values for erred or lost audio signal. To minimize undesirable audible artifacts which may be introduced into the audio signal by virtue of the substitution process, the rate of substitution is monitored. When the rate of substitution exceeds a predetermined rate, the higher frequency components of the audio signal, including the substituted values, are attenuated.

Abstract: With an optical playback device, for example, with a compact disk player, care should be taken to see that the light beam scanning the data radiates as perpendicular as possible onto the disk. However, as a consequence of disk slap or chattering, the radial and the tangential angles alter during every revolution of the disk. As a result of the tolerances in the disk and the device, the optical axis deviates from the perpendicular in many cases. In order to regulate the radial angle .phi.R and the tangential angle .phi.T, under which the light beam strikes the disk, the data signal is demodulated in an amplitude demodulator. The regulating signal UR=C* sin .phi.* cos .alpha. for the radial angle .phi.R and the regulating signal UT=-C* cos .phi.* sin .alpha. for the tangential angle .phi.T are generated from the amplitude C and the phase position .phi. of the demodulated data signal.

Abstract: In CD-players with a memory having A storage positions for the storage of titles recorded on a CD-record it can happen, that more titles C are on the CD-record than storage positions A provided therefore in the CD-record. In order to use the storage space better in these cases and to keep the access times to the single titles low, the difference of the start times of each two consecutive titles are stored, instead of storing the start times of the individual titles. The more titles that are recorded on a inserted CD-record, the better the storage space is used, and the more the access times are reduced.

Abstract: A record player with a scanner for record disks is provided, where the vertical recording track angle .alpha. is to be placed within predetermined limits, but where, in general, the value of .alpha. is not known. The scanner comprises a transducer which generates useful signals and which is provided with elastically supported and therefore movable scanning elements. According to the invention, means are provided for determining the difference .alpha.-.beta. of the recording track angle .alpha. and of the tracking track angle .beta..

A record player with a tracking sound pick-up arm for the tracking of record disks is provided. Means for tracking a groove on a side of a record disk are disposed elastically supported and thus movable on the sound pick-up arm.

A scanning head can be pivoted around an axis in order to provide fine control. The scanning head is maintained in a defined middle position with springs. A magnetic circuit is constructed of a permanent magnet, pole shoes and a coil with a core provides a controllable or automatically controllable movement of the scanning head. The displacement of the scanning head can be determined with a piezoelectric converter, which is disposed between one of the two springs and the support associated with the pole shoes. Desired displacements of the scanning head can be obtained with a second electromechanical converter, which is disposed between the other spring and the other support, after application of a suitable voltage.

Abstract: A radially acting track follower system is provided with an optical scanner pickup for an audio or video record playback apparatus. The system generates three light spots disposed on a line with a movable phase grating (diffraction grating) and the three spots can be adjusted relative to the tangent at the track pickup scanning location. The middle or main light spot serves to provide scanning of the track signal information. The two outer or auxiliary light spots serve to provide readjustment. They are displaced radially oppositely to each other by equal amounts and are disposed at equal distances from the middle spot. The light intensity of the outer spots is picked up by detectors and processed into control signals. These are used as a drive for the phase grating, which can be controlled around its center point and the rotation axis of the phase grating coincides with the light beam, which can be provided by a semiconductor laser.
