Abstract: A method for operating an electronic device includes: having a touch sensitive display configured to be rolled into or unrolled out of a first retainment structure along a first direction. The first retainment structure includes a conductive material disposed within the first retainment structure. The method includes unrolling or rolling the touch sensitive display to an unrolled position along the first direction; determining that the touch sensitive display is detecting contact at a plurality of mutual sensing locations using a mutual sensing process; determining that the touch sensitive display is detecting contact at a plurality self-sensing locations using a self-sensing process; determining a plurality of multi-mutual sensing locations based on multi-mutual sensing values obtained from a multi-mutual sensing process; and determining the unrolled position along the first direction based on the plurality of mutual sensing locations, the plurality self-sensing locations, and the plurality of multi-mutual sensing locations.

Abstract: In an embodiment, a method includes performing a calibration of a first touch cell of a touch screen, where performing the calibration includes: receiving a first code associated with the first touch cell; receiving a second code associated with the first touch cell; determining whether there is an indication of a touch of the touch screen based on the first and second codes; generating a raw code based on the first or second codes; receiving a third code associated with the first touch cell; determining whether the third code matches the raw code; and in response to determining that there is no indication of a touch of the touch screen based on the first and second codes, and that the third code matches the raw code, updating a calibration code associated with the first touch cell based on the raw code or the third code.

Abstract: Disclosed herein is a strain gauge including a substrate, with a first Wheatstone bridge arrangement of resistors disposed on a first surface of the substrate, and a second Wheatstone bridge arrangement of resistors disposed remotely from the first Wheatstone bridge arrangement of resistors. The resistors of the first Wheatstone bridge arrangement are equal in resistance to one another, while the resistors of the second Wheatstone bridge arrangement are unequal in resistance to one another and unequal to those of the first Wheatstone bridge arrangement. The first Wheatstone bridge arrangement of resistors are electrically connected in parallel with the second Wheatstone bridge arrangement of resistors such that each resistor of the first Wheatstone bridge arrangement is electrically connected in parallel with a different resistor of the second Wheatstone bridge arrangement.
