Assignee: SENSEL, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 3:
4. The system of claim 1, wherein the controller is configured to:
access the first set of electrical values, from the first multi-layer inductor, representing voltage across the first multi-layer inductor;
detect the first change in electrical value comprising a first voltage of a first polarity across the first multi-layer inductor at the first time;
register the first fingerprint input on the cover layer in response to detecting the first voltage of the first polarity across the first inductor;
interpret a first force magnitude for the first fingerprint input based on the first voltage of the first polarity;
trigger the oscillating voltage across the first multi-layer inductor during the first haptic feedback cycle in response to the first force magnitude exceeding a target force magnitude and in response to the first fingerprint image deviating from the target fingerprint image;
detect a second voltage of a second polarity, opposite the first polarity, across the first multi-layer inductor at a second time succeeding the first time;
register release of the first fingerprint input from the cover layer in response to detecting the second voltage at the second polarity across the first multi-layer inductor; and
trigger a second oscillating voltage, different from the first oscillating voltage, across the first multi-layer inductor during a second haptic feedback cycle in response to registering release of the first fingerprint input from the cover layer.
