Abstract
The present disclosure relates generally to devices, systems, and methods for supporting different load conditions in a data/power link. In one example, a device includes a transformer that has a first tap with a first turns ratio and a second tap with a second turns ratio. The device further includes electronics and circuitry. The circuitry is configured to selectively couple the electronics to the first tap of the transformer for a first application and to couple the electronics to the second tap of the transformer for a second application.
Claims21
A hearing prosthesis, comprising:
- a transmitter circuit configured to transmit wireless signals to a receiver circuit over a wireless communication link;
- a signal generator configured to generate electrical signals useable to drive the transmitter circuit to transmit the wireless signals,
- wherein the signal generator includes a frame controller configured to dynamically vary a duty cycle of the electrical signals based on one or more conditions of the wireless communication link.
A hearing prosthesis, comprising:
- a primary coil;
- and
- a signal generator coupled to the primary coil and configured to energize the primary coil to transmit signals to a secondary coil,
- wherein the signal generator is configured to energize the primary coil to transmit electrical signals to the secondary coil at a first duty cycle for operation in a first mode and to energize the primary coil to transmit electrical signals to the secondary coil at a second duty cycle for operation in a second mode,
- wherein the first and second duty cycles are different from one another.
A method, comprising:
- generating oscillating electrical signals with a signal generator of an external unit of a hearing prosthesis;
- energizing a transmitter circuit with the oscillating electrical signals to transmit the electrical signals to a receiver circuit disposed in an implantable unit of the hearing prosthesis via an inductive link coupling the transmitter circuit to the receiver circuit;
- dynamically varying a duty cycle of the oscillating electrical signals based on one or more conditions of the inductive link.
