Abstract
A charging kit for inductively charging a rechargeable hearing instrument having an inductive coil, includes: a base unit having a first cavity; and an adapter configured to be received by the first cavity, wherein the adapter comprises a second cavity configured to receive the rechargeable hearing instrument; wherein the base unit is configured to determine a characteristic of the inductive coil of the hearing instrument; wherein the base unit is configured to provide a current by the base unit based at least in part on the determined characteristic of the inductive coil; and wherein the base unit is configured to inductively charge the rechargeable hearing instrument.
Claims42
A charging kit for inductively charging a hearing instrument having an inductive coil, comprising:
- a base unit having a first cavity;
- an adapter in the first cavity, wherein the adapter comprises a second cavity configured to receive the hearing instrument;
- and
- a charging coil, wherein the second cavity of the adapter is located away from a center of the charging coil;
- wherein the base unit is configured to determine a characteristic of the inductive coil of the hearing instrument;
- wherein the base unit is configured to provide a current by the base unit based at least in part on the determined characteristic of the inductive coil;
- and
- wherein the base unit is configured to inductively charge the hearing instrument.
A method for inductively charging a hearing instrument having an inductive coil, the method being performed by a charging kit comprising a base unit having a first cavity, and an adapter in the first cavity, and wherein the adapter comprises a second cavity configured to receive the hearing instrument, the method comprising:
- receiving the hearing instrument by the second cavity of the adapter;
- receiving the adapter by the first cavity of the base unit;
- determining a characteristic of the inductive coil of the hearing instrument;
- providing a current by the base unit based at least in part on the determined characteristic of the inductive coil;
- and
- inductively charging the hearing instrument;
- wherein the hearing instrument is charged using a charging coil of the charging kit, wherein the second cavity of the adapter is located away from a center of the charging coil.
A charging kit for inductively charging a hearing instrument having an inductive coil, comprising:
- a base unit having a first cavity;
- an adapter in the first cavity of the base unit, wherein the adapter comprises a second cavity configured to receive the hearing instrument;
- and
- a charging coil;
- wherein the base unit is configured to determine a characteristic associated with a charging of the hearing instrument;
- wherein the base unit is configured to provide a current by the base unit based at least in part on the determined characteristic;
- wherein the base unit is configured to inductively charge the hearing instrument;
- and
- wherein the base unit is configured to supply AC current at at least two different frequencies to the charging coil while the hearing instrument is in the adapter.
