Abstract

An aircraft sensor system including a primary module configured to be attached to an aircraft portion and operative to transmit electrical power wirelessly. A secondary module configured to be attached to an aircraft component, the secondary module operative to receive electrical power wirelessly from the primary module. At least one sensor configured to be operatively attached to a portion of the aircraft component and electrically coupled to the secondary module, wherein the at least one sensor is operative to measure a desired parameter of the aircraft component.

Claims

1. An aircraft sensor system, the system comprising:

a primary module configured to be attached to an aircraft portion, the primary module operative to transmit electrical power wirelessly;

a secondary module configured to be attached to an aircraft component, the secondary module operative to receive electrical power wirelessly from the primary module when the aircraft component is in a first position;

at least one sensor configured to be operatively attached to a portion of the aircraft component and electrically coupled to the secondary module, wherein the at least one sensor is operative to measure a desired parameter of the aircraft component; and

a power storage module configured to be mounted in close proximity to the aircraft component and being electrically coupled to the at least one sensor, the power storage module operative to provide electrical power to the at least one sensor when the aircraft component is in a second position in which the secondary module cannot receive sufficient electrical power wirelessly from the primary module.

2. The aircraft sensor system of claim 1, wherein the primary module and secondary module are operative to transfer electrical power wirelessly by inductive coupling.

3. The aircraft sensor system of claim 1, wherein the primary module and secondary module are operative to transfer electrical power wirelessly by resonant inductive coupling.

5. The aircraft sensor system of claim 1, wherein the primary module is configured to be mounted in close proximity to the secondary module.

6. The aircraft sensor system of claim 1, wherein the power storage module includes at least one rechargeable battery configured to store electrical power.

7. The aircraft sensor system of claim 1, wherein the power storage module includes at least one capacitor configured to store electrical power.

8. The aircraft sensor system of claim 1, wherein the power storage module is configured to provide electrical power to the at least one sensor during periods when the secondary module is not receiving electrical power from the primary module.

9. The aircraft sensor system of claim 1, wherein the secondary module is configured to charge the power storage module with electrical power received from the primary module.

10. An aircraft sensor system, the system comprising:

a primary module configured to be attached to an aircraft portion, the primary module operative to transmit electrical power wirelessly and operative to receive data wirelessly;

a secondary module configured to be attached to an aircraft component, the secondary module operative to receive electrical power wirelessly from the primary module when the aircraft component is in a first position, the secondary module further configured to transmit data wirelessly to the primary module;

at least one sensor configured to be operatively attached to a portion of the aircraft component and electrically coupled to the secondary module, wherein the at least one sensor is operative to measure a desired parameter of the aircraft component and provide corresponding data to the secondary module; and

a power storage module configured to be mounted in close proximity to the aircraft component and being electrically coupled to the at least one sensor, the power storage module operative to provide electrical power to the at least one sensor when the aircraft component is in a second position in which the secondary module cannot receive sufficient electrical power wirelessly from the primary module.
