Abstract: The device for electronically simulating a component position includes a first counter (40,42) which counts counter pulses (Zt) determined by respective occurrences of a periodic event marking respective component positions; a second counter (30) which, in response to occurrence of a first event (e2), starts a third counter (34) which counts at a counting rate faster than that of the second counter (30) so as to repeatedly run through a predetermined value range (Z') until occurrence of a subsequent event (e3) and which produces a basic clock pulse (Co) each time a final value (y) of the predetermined value range (Z') is reached; and a readjustment circuit (38) which produces the counter pulses (Zt) from the basic clock pulses (Co).

Abstract: A method for periodic transmission of data between control devices (10, 11, 12) interconnected via a serial bus (20) is provided, particularly for the transmission of synchronization data. The control devices (10, 11, 12) each have a serial interface (17,17'17") and an arithmetic/control unit (15,18). Data are provided for transmission by the arithmetic/control unit (15, 18) of the control device transmitting the data and are included in a message sent over the serial bus (20). To this end, a transmission job for transmitting the message is provided to the serial interface (17) of control device (10) transmitting the message which controls the transmission. However, this occurs so that, when transmitting the message, use is not made of the data provided at the instant of providing the transmission job, but instead of updated data provided by the arithmetic/control unit in the interim since the instant of giving the transmission job.

Abstract: The controller system includes a control logic device and a controller arranged between a processor and the control logic device. The control logic device includes a stored initiation value for initiating a task activated by the control logic device, a device for making a comparison between the stored initiation value residing in the control logic device and an incrementally changing time value and a device for initiating the task when the stored initiation value therein corresponds to the incrementally changing time value.

Abstract: The electronic circuit device for analysis of a periodically repeating digital signal from a rotational position transmitter, which includes groups of events, each of which has a first and last event and at least one additional event between them, includes a first counter (10) for counting periodically generated pulses (t1) fed to it; a counting device (14) for counting the events in each group; a detecting device for the first and last event of each group; and a circuit device for feeding the periodically generated pulses (t1) to the first counter between the first and last event detected by the detecting device to form a counter count.

Abstract: An electronic control device for controlling a fuel injection starting time and an injection duration in an internal combustion engine has an event device (E) which generates an event signal (ES) as a function of a prescribed occurrence of an event and a device for controlling or setting the injection duration including a first register (R1), a loading device (L) and a counter (Z). The event device (E) includes a second register (R2), a clock device (TE) and a comparator (K) which compares a stored register value in the second register (R2) with clock data from the clock device (TE) to produce a comparator signal for generation of the event signal (ES) when the stored register value corresponds to the clock data from the clock device.

Abstract: The present invention relates to an electronic meter circuit for a time comparison measurement between two successive periodic events with which the signal time ratios between two times two successive events can be recognized by a simple method.The electronic meter circuits comprises a reference meter to be loaded with a reset value when a first event occurs and for reference meter to start to count at a clock frequency and when a second event occurs, reference meter starts to count in the opposite direction at a clock frequency until a third event occurs, and when the third event occurs, meter reading forms a reference value for the ratio of the signal times between the occurrence of the first and second events and between the second and third events.
