Abstract: 379 CAN    INVENTORS: PAUL FRIEDLI and HANS GERHARD SUSS           INVENTION: APPARATUS FOR CONTROLLING THE ACCESS OF            PROCESSORS AT A DATA LINE                          ABSTRACT OF THE DISCLOSURE     An apparatus for controlling the access of a plurality of microprocessors at a data line. The micropro-cessors are connected by interface components or blocks, logic switching circuits and bus drivers with two lines or conductors.      By means of an access requisition or demand of a processor there is initiated a signal change of the first line. This signal change causes the transformation of data which is specific to the processor into a delay of a priority signal, upon the occurrence of which there is accomplished a signal change of the second line. As a function thereof there appears at an input of the interface component a signal change which is indicative of the availability of the data line. Upon simultaneous occurrence of access requisitions or demands of a number of processors the signal change of the second line is brought about by that pro-cessor whose priority signal possesses the smallest delay. The signal change of the second line prevents the occurrence of the priority signals possessing the greater time-delays and which are correlated to the remaining processors. At these processors there thus cannot occur any signal change at the input of the related interface component or block and which indicates the availability of the data line.

Abstract: ABSTRACT OF THE DISCLOSURE:     The present invention relates to an optical measuring device for measuring physical quantities, comprising a measuring transducer and an evaluating electronic unit, interconnected by a light-transmitting system. The optical measuring device also comprises an optical element for coupling in light from a light source to the light-transmitting system, and for coupling out light from the light-transmitting system to a photo-detector in the evaluating electronic unit. The optical measuring device further comprises a first element for polarizing the light from the light source and a second element for polarizing the light to the photo-detector, wherein there is a difference in the direction of polarization between the first and second polarizing elements which is chosen so that light reflections in the system in and adjacent to the evaluating electronic unit are substantially blocked from the photo detector by the second polarizing element.
