摘要： A detection apparatus for detecting perforation holes (3) of a cinematographic film (1) comprises at least one light source (6, 6', 6"), at least one scanning sensor (7, 7', 7"), which is arranged so as to receive light (8) emitted by the light source (6, 6', 6") after interaction with a perforation zone of the film (1), and an evaluation circuit (13, 14; 13, 13', 14, 16; 13", 14") for detecting, by means of an output signal (L) of the scanning sensor (7, 7', 7"), when an edge of a perforation hole (3) passes through between light source (6, 6', 6") and scanning sensor (7, 7', 7"). The light source (6, 6', 6") emits light which is polarized with a first polarization and the scanning sensor (7, 7', 7") is sensitive selectively to light with a second polarization.

摘要： A circuit is proposed which has a memory to which input data can be written at different write addresses with a first clock rate and from which output data can be read at different read addresses with a second clock rate. The memory can be fed a write reset pulse that resets the write address to an initial value. In addition, the memory can be fed a read reset pulse by means of which the data are output in a fixed temporal relationship. Finally, the circuit proposed is provided with switching means in order to derive the read reset pulse from the write reset pulse. This ensures that the two reset pulses cannot occur simultaneously.

摘要： A method and an arrangement for determining the position of a tape-like medium are proposed. The method provides for counting pulses which are supplied to the arrangement for determining the position to be counted, blocked or cancelled depending on the respective transport state. To this end, it is established whether the transport direction has been constant for a defined amount of time or over a defined distance. The transport direction determines whether the counter is incremented or decremented. In addition, counting pulses which rapidly follow one another are blocked in order to avoid undesirable double triggering. In order to avoid losing blocked counting pulses in an undesirable manner, the latter are stored and are applied to the counter, or discarded, depending on the transport state before and after blocking.
