Abstract
A capacitance module may include a substrate, a set of electrodes formed on the substrate where a first generally linear electrode of the set may be aligned with a second generally linear electrode of the set; a controller in communication with the set of electrodes; and memory having programmed instructions configured to cause the controller, when executed, to measure a change in capacitance; and determine a tilt of an object in proximity to the substrate based, in part, on the measured change in capacitance.
Claims20
A capacitance module, comprising:
- a substrate,
- a set of electrodes formed on the substrate where a first generally linear electrode of the set is aligned with a second generally linear electrode of the set;
- a controller in communication with the set of electrodes;
- memory having programmed instructions configured to cause the controller, when executed, to:
- measure a change in capacitance;
- and
- determine a tilt of an object in proximity to the substrate based, in part, on the measured change in capacitance.
A computer-program product, the computer-program product comprising a non-transitory computer-readable medium storing instructions executable by a controller to:
- receive a first measurement from a first generally linear electrode;
- receive a second measurement from a second generally linear electrode, where the first generally linear electrode is aligned with the second generally linear electrode;
- analyze the first measurement and the second measurement;
- and
- determine a tilt of an object based on analysis.
A computer-program product, the computer-program product comprising a non-transitory computer-readable medium storing instructions executable by a controller to:
- receive a capacitance measurement from a first electrode;
- determine that an object is tilting in a first direction when the capacitance measurement is positive and determine that the object is tilting in a second direction when the capacitance measurement is negative.
