  • Apparatus and methods involving control of piezoelectric resonance circuits
    Patent number: 12047018
    Abstract: In certain examples, methods and semiconductor structures are directed to operation of a piezoelectric-based device (e.g., a DC-DC converter) and such operation may involve selectively switching inputs of the piezoelectric-based device at a modulation frequency and, in response, decoupling of the modulation frequency from output power delivered by the piezoelectric-based device. In some examples, the inputs of the piezoelectric-based device are selectively switched to cause decoupling the modulation frequency from output power delivered by the piezoelectric-based device and/or cause operation of the piezoelectric-based device without spurious mode operation.

  • Systems and methods for generating power using a combustion source
    Patent number: 11280196
    Abstract: In one embodiment, a power generation system includes a pulse detonation engine including a combustion chamber, a linear power generator including a working chamber, and a nozzle positioned between the combustion chamber and the working chamber that expands exhaust gas expelled from the combustion chamber, wherein the nozzle increases thermodynamic efficiency of the system.
