Patent number: 11615318Abstract: A pattern recognition device comprising: a coupled network of damped, nonlinear, dynamic elements configured to generate an output response in response to at least one environmental condition, wherein each element has an associated multi-stable potential energy function that defines multiple energy states of an individual element, and wherein the elements are tuned such that environmental noise triggers stochastic resonance between energy levels of at least two elements; a processor configured to monitor the output response over time and to determine a probability that the pattern recognition device is in a given state based on the monitored output response; and detecting a pattern in the at least one environmental condition based on the probability.Type: GrantFiled: July 23, 2021Date of Patent: March 28, 2023Assignee: United States of America as represented by the Secretary of the NavyInventors: Paul R. De La Houssaye, Benjamin J. Migliori, Adi Ratan Bulsara, Chriswell Hutchens, Justin M. Mauger

Patent number: 11510148Abstract: An autonomous sensor that includes a snap-through buckling beam, a proof mass, an ultra-low-power microcontroller unit, a wireless transmitter, a power management unit, and a power storage unit. The snap-through buckling beam produces mechanical energy. The proof mass is attached to the snap-through buckling beam. The proof mass transfers mechanical energy to two piezoelectric transducers that convert the mechanical energy into electrical energy and produce an output signal. The ultra-low-power microcontroller unit converts the output signal into output data. The wireless transmitter transfers the output data to an external device. The power management unit provides the electrical energy to the ultra-low-power microcontroller unit and the wireless transmitter. The power storage unit is rechargeable, stores electrical energy from the two piezoelectric transducers, and non-replaceable. The autonomous sensor simultaneously harvests energy and measures vibrations in an external environment.Type: GrantFiled: December 1, 2020Date of Patent: November 22, 2022Assignee: United States of America as represented by the Secretary of the NavyInventors: Adi Ratan Bulsara, Bruno Ando, Salvatore Baglio, Vincenzo Marletta

Patent number: 9470733Abstract: A sensor for detecting both magnetic fields and electric fields can include at least one Sawyer-Tower (ST) circuit that can incorporate a multiferroic capacitor. An odd number of ST circuits coupled together in a ring configuration, so that for each ST circuit, the output of one ST circuit is an input to another of the ST circuits. The multiferroic capacitors can include a multiferroic layer that can be deposed on a substrate. For each multiferroic capacitor, the deposition process can cause an inherent amount of impurities in the multiferroic layer. The number of said odd number of ST circuits to be coupled together is chosen according to the amount of impurities, to “forgive” the impurities. The higher the level of impurities in the multiferroic layers, that more ST circuits that are required in the ring to achieve the same sensor sensitivity. BDFO can be chosen for the multiferroic material.Type: GrantFiled: November 17, 2014Date of Patent: October 18, 2016Assignee: The United States of America, as Represented by the Secretary of the NavyInventors: Salvatore Baglio, Bruno Ando, Adi Ratan Bulsara, Angela Beninato, Teresa Emery
