Patent number: 9962085Abstract: An inductive wireless power transfer and communication system includes an electrostatic shield for one of the coils. The electrostatic shield is inductively coupled with the coil and is configured as an open circuit. A signal processing element or elements, especially a modulator or a demodulator, are connected across the electrical discontinuity in the electrostatic shield. Because the electrostatic shield is inductively coupled to the coil, the modulator or demodulator can operate on the signal on the coil.Type: GrantFiled: July 30, 2015Date of Patent: May 8, 2018Assignee: The Alfred E. Mann Foundation For Scientific ResearchInventor: Glen A. Griffith

The electrostatic shield is inductively coupled with the coil and is configured as an open circuit. A signal processing element or elements, especially a modulator or a demodulator, are connected across the electrical discontinuity in the electrostatic shield. Because the electrostatic shield is inductively coupled to the coil, the modulator or demodulator can operate on the signal on the coil. A variable impedance element is connected across the electrical discontinuity in the electrostatic shield. Because the electrostatic shield is inductively coupled to the coil, the variable impedance element can tune the impedance of the system.Type: ApplicationFiled: February 3, 2016Publication date: August 4, 2016Applicant: The Alfred E.

Patent number: 8275462Abstract: Systems and methods for efficiently transmitting power using a high frequency (e.g., RF) telemetry transmitter are provided. The telemetry transmitter may include a fixed clock source (which may provide a fixed clock signal), telemetry phase shift circuitry (which may include switching circuitry and phase shifting circuitry), and a push-pull network. The telemetry phase shift circuitry generates a phase shifted clock signal that is phase shifted with respect to the fixed clock signal. The fixed and phase shifted clock signals may drive the switching circuitry to produce a high frequency signal that is passed through the push-pull network. The power or magnitude of the high frequency signal is based on the phase delay between the fixed clock signal and the phase shifted clock signal.Type: GrantFiled: August 10, 2011Date of Patent: September 25, 2012Assignee: Advanced BionicsInventor: Glen A.

Patent number: 7623929Abstract: A detection circuit for sensing signals in an implantable cochlear stimulator is provided. The detection circuit has a primary coil winding which is part of the detected circuit. The primary coil is placed adjacent to and coupled electromagnetically to a secondary coil winding which is connected to an isolated circuit. The isolated circuit has circuit means for processing the induced current in the isolated current. Because a transformer is employed, the detection circuit draws only minimal power from the detected circuit, and the sensed output voltage can be flexibly scaled.Type: GrantFiled: August 29, 2003Date of Patent: November 24, 2009Assignee: Advanced Bionics, LLCInventor: Glen A Griffith

Patent number: 7444185Abstract: An active electrode array provides a programmable number of electrode contacts through which stimulation current may be selectively delivered to surrounding tissue, preferably through the use of appropriate stimulation groups. The active electrode array provides a large number of both medial and lateral contacts, any one of which may be selected to apply a stimulus pulse through active switching elements included within the array. The active switching elements included within the array operate at a very low compliance voltage, thereby reducing power consumption.Type: GrantFiled: September 23, 2005Date of Patent: October 28, 2008Assignee: Advanced Bionics, LLCInventors: Michael A Faltys, Glen A Griffith, William VanBrooks Harrison
