US Patent 11663809 Thin-film active surface for fuzzy template matching

An apparatus for performing fuzzy template matching includes multiple damped oscillators arranged in at least one two-dimensional matrix, each of the damped oscillators being capacitively coupled to at least one adjacent damped oscillator in the matrix. The apparatus further includes peripheral circuitry coupled with the damped oscillators. The peripheral circuitry is configured to selectively interface with the damped oscillators, as a function of one or more control signals supplied to the peripheral circuitry, and to generate at least one output signal indicative of an accuracy of matching between a template pattern and an input pattern.
