Abstract: P. JOOS-W. VERBIEST 2-4 ABSTRACT          STATISTICAL MEASUREMENT EQUIPMENT AND  TELECOMMUNICATION SYSTEM USING SAME The measurement equipment (SMC) is used in a telecommunication switching system to check if the cell rate of each of a plurality of individual cell streams multiplexed in a same link remains within the limits on the basis of which its multiplexing was allowed.  To this end the equipment checks at the end of each measurement interval (MTI) and for a plurality of cell rates [(M-S)/A, (M-S/2)/A, ... ] if the expected probabilities to exceed these cell rates are exceeded or not.  In the positive the cell rate is limited by dropping cells.  Thus an expected complementary (with respect to 1) cumulative probability distribution function of the cell rate is approximated by a staircase-shaped function.

Title: Optical/magnetic composite head having magnetic and optical heads in one integrated unit
IPC: G11B7/1372
Filed: 1990-03-29
Abstract: A photomagnetic composite head includes a magnetic head and an optical head integrated into one unit.   An optical waveguide path of the optical head is located on the surface of the magnetic head that faces a recording medium.  A laser beam passes through the optical waveguide path and is irradiated on a point on the recording medium where a magnetic field is impressed from the magnetic head. Accordingly, recording can be performed under a condition in which the coercivity of the recording medium has been reduced by the laser beam,  thus making it possible to achieve high density recording by using a recording medium with a high coercivity.
