Abstract

Denne oppfinnelsen angår en fremgangsmåte for bestemmelse av hastigheten til en overflatestruktur, særlig på et fingeroverflate, som beveger seg relativt til to i bevegelsesretningen plasserte sensorer, hvilke sensorer har en forutbestemt innbyrdes avstand og der sensorene måler variasjon i en forutbestemt egenskap ved overflatestrukturen. Fremgangsmåten er kjennetegnet ved gjentatte målinger av fingeroverflatens egenskaper og deteksjon av posisjonen til en forutbestemt verdi langs tidsaksen for hver sensor, og basert på disse posisjonene i tillegg til den kjente avstanden mellom sensorene beregning av overflatens hastighet i forhold til sensorene.
