Patent number: 11722017Abstract: An adaptive system for efficient and long-range wireless power delivery using magnetically coupled resonators responds to changes in a dynamic environment, and maintains high efficiency over a narrow or fixed frequency range. The system uses adaptive impedance matching to maintain high efficiency. The wireless power transfer system includes a drive inductor coupled to a high-Q transmitter coil, and a load inductor coupled to a high-Q receiver coil. The transmitter coil and receiver coil for a magnetically coupled resonator. A first matching network is (i) operably coupled to the drive inductor and configured to selectively adjust the impedance between the drive inductor and the transmitter coil, or (ii) is operably coupled to the load inductor and configured to selectively adjust the impedance between the load inductor and the receiver coil.Type: GrantFiled: July 15, 2021Date of Patent: August 8, 2023Assignee: University of Washington through its Center for CommercializationInventors: Joshua R. Smith, Benjamin H. Waters, Scott Wisdom, Alanson P. Sample

Patent number: 9415149Abstract: A ventricular assist device (VAD) system includes one or more external subsystems including an amplifier energizing a drive loop with alternating current, and a Tx resonator inductively coupled to the drive loop. An implanted subsystem includes a VAD, an Rx resonator that forms a magnetically coupled resonator with the Tx resonator, and a load loop for providing power to the VAD that is inductively coupled to the Rx resonator. A sensor monitors the drive loop and a controller uses the sensor data to adjust a system parameter to optimize energy transfer performance. Distributing a plurality of the external subsystems throughout a defined space provides a patient with freedom of movement within the defined space.Type: GrantFiled: September 9, 2014Date of Patent: August 16, 2016Assignee: Yale UniversityInventors: Joshua R.
