Title:
METHOD FOR DETERMINING POSITION OF INDEXED POTENTIOMETER AND APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/001576
Kind Code:
A3
Abstract:
An apparatus for determining potentiometer indexed position is disclosed. The apparatus (100) comprises at least one potentiometer having a resistance R, a resistance R1 from a first end of the potentiometer to its wiper, and a resistance R2 from a second end of the potentiometer to its wiper; a capacitor (C); and a microcontroller (M) adapted to alternately put said resistances R1 and R2 in a circuit to obtain time (t
1
) required for said capacitor to charge and time (t
2
) required for said capacitor to discharge, to determine said potentiometer indexed position using equation [t
1
/(t
1
i+t
2
)]*total number of said potentiometer indexed positions.
