Abstract

The setting process of many electronic devices is a lengthy process, because of the (digital) display which clocks at a constant speed. In the case of rapidly clocking displays, a precise setting of a value during the setting process would hardly be possible, owing to the poor reaction time of humans. By means of a pressure sensor integrated into the setting pushbutton, the clock speed of the display can be varied as a function of the pressing force, by which means a higher operating comfort is achieved in many electronic devices.

Description

Die Erfindung betrifft einen Drucktaster mit integriertem Drucksensor, der in Abhängigkeit der Druckkraft eine physikalische Größe, z. B. Wider­ stand, Kapazität, Resonanzfrequenz, ändert.The invention relates to a push button integrated pressure sensor, which depends on the Compressive force a physical quantity, e.g. B. Against stand, capacity, resonance frequency, changes.

Der Einsatz dieses speziellen Drucktasters ver­ mindert die Einstellzeiten vieler elektrischer und elektronischer Geräte erheblich, und macht die Bedienung wesentlich komfortabler.The use of this special push button ver reduces the response times of many electrical and electronic devices considerably, and makes the operation is much more comfortable.

In vielen elektronischen Geräten mit einstellbarer Anzeige, z. B. Digitaluhr, Digitaltimer usw. ist auf Grund der zu berücksichtigenden Reak­ tionszeit des Menschen der Einstellvorgang, durch die relativ langsam weitertaktende An­ zeige, ein langwieriger Prozeß.In many electronic devices with adjustable Display, e.g. B. digital clock, digital timer, etc. is due to the reak to be considered time of man the adjustment process, due to the relatively slow clock cycle show a lengthy process.

Eine Beschleunigung dieses Prozesses wird erreicht, da die bedienende Person durch die eigene Druckkraft die Taktrate der Anzeige be­ stimmt und während des Einstellvorganges verän­ dern kann.This process will accelerate achieved because the operator through the own pressure force the clock rate of the ad be correct and change during the setting process who can.

Fig. 1 zeigt einen möglichen konstruktiven Aufbau im Zusammenhang mit einem Oszillator und einer Digitalanzeige: Fig. 1 shows a possible structural configuration in connection with an oscillator and a digital display:

Der Druckkraft wird über einen Stift (1), der durch die Feder (2) in die Ausgangslage zu­ rückkehrt, auf den Sensor (3) übertragen. Der, in diesem Beispiel, kapazitive Drucksensor (3) verändert die Frequenz eines nachgeschalte­ ten Oszillators (4), der wiederum die Taktrate der einstellbaren Anzeige (5) erzeugt.The pressure force is transferred to the sensor ( 3 ) via a pin ( 1 ), which returns to the starting position by the spring ( 2 ). The, in this example, capacitive pressure sensor ( 3 ) changes the frequency of a downstream oscillator ( 4 ), which in turn generates the clock rate of the adjustable display ( 5 ).
