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.
Claims17
A capacitance module, comprising:
- a substrate,
- a set of electrodes formed on the substrate where a first electrode of the set is aligned with a second 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 within a proximity sense range to the substrate based, in part, on the measured change in capacitance;
- wherein measuring a change in capacitance includes transmitting a positive signal with the first electrode and transmitting a negative signal with the second electrode.
A non-transitory computer-readable medium storing instructions executable by a controller to:
- instruct a first electrode to transmit a positive signal;
- instruct a second electrode to transmit a negative signal;
- receive a first measurement from the first electrode;
- receive a second measurement from the second electrode, where the first electrode is aligned with the second electrode;
- analyze the first measurement and the second measurement;
- and
- 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.
