Abstract

A method and an electro-mechanical arrangement for the generating and processing of electrical impulses for the setting or correction of an electronic digital display through the intermediary of an impulse generator. The impulse generator consists of an impulse transmitter and an impulse collector whereby, by means of the impulse emitter which evidences a plurality of impulse-generating elements, preferably arranged at uniform spacings in a circular path relative to a rotational axis, a plurality of electrical contacts are adapted to be closed in cooperation with the impulse-generating elements. The contacts of the impulse collector, generating mutually timewise displaced but still overlapping impulses whose frequency is proportional to the relative speed between the impulse transmitter and the impulse collector and whose phase position, in essence the phase lead and phase lag, is dependent upon the relative direction of rotation between the impulse transmitter and the impulse collector.

Dependent claims

In a method for the generating and processing of electrical impulses for the setting and correcting of an electronic digital display through a pulse generator generating at least two timewise displaced but still overlapping impulse trains by the rotation of an impulse transmitter against an impulse collector, the frequency of the impulses being dependent upon the rotational speed of the impulse transmitter relative to the impulse collector and the opposite phase from the direction of rotation of the impulse transmitter relative to the impulse collector, the improvement comprising of the following sequentially timed steps:

(a) introducing said impulse trains into a microprocessor;
(b) storing digital impulse informations contained in said microprocessor which newly appears at the generator output at each impulse change in a first memory storage.
(c) introducing a further digital impulse information present at the generator output preceding the impulse change into a second memory storage;
(d) combining said two impulse informations into a bit word having at least 4-bits;
(e) comparing said bit word with fixed stored bit words which are associated with a predetermined direction of rotation of the impulse generator axis to obtain forward-rearward count information;
(f) introducing the forward-rearward count information obtained through the comparison into a counter;
(g) decoding the count condition for an electronic digital display,
(h) and transferring the last impulse information present at the generator output so as to be combinable with newly storaged information into a bit word with at least 4-bits.

In an electromechanical arrangement for effectuating a method of generating and processing of electrical impulses for the setting or correcting of an electronic digital display, including an impulse generator having an impulse transmitter and an impulse collector, said impulse transmitter being a plurality of impulse-generating elements arranged in uniform spacing along a circular path concentrically relative to an axis of rotation, said impulse collector having a plurality of electrical contacts closable in cooperation with said impulse-generating elements and which generate timewise displaced but overlapping impulse trains where frequency is proportional to the relative speed between the impulse transmitter and the impulse collector and their phase position, phase lead and phase lag, dependent upon the relative direction of rotation between the impulse transmitter and the impulse collector, the improvement comprising:

An electronic component being connected to the output of said impulse generator, said component comprising a first storage and a second storage for the impulses generated by said impulse generator, a program reference value memory storage, control means for controlling said storages and comparing the informations contained in said storages, a forwards-rearwards counter and a decoder for an electronic digital display, the impulse information newly formed at the actuation of the impulse generator at each impulse change being storable in said first storage, at this time point the impulse information preceding the last impulse change being storable in said second storage, wherein through comparison of the stored contents of said first and second storages with the fixed information in the memory storage identifying the phase position of the impulses there is identified the direction of rotation of the impulse generator axis and the count input of the forwards-rearwards counter responsive to the sense of rotation is controllable, and the count content for the digital display is adapted to be decoded and the information stored in said first storage is transferable into said second storage.
