Abstract

A non-destructive inspection apparatus, system and associated method are provided to facilitate the inspection of a workpiece. The non-destructive inspection apparatus includes an ultrasonic sensor configured to be placed in operable contact with the workpiece. The ultrasonic sensor is configured to emit ultrasonic signals into the workpiece and to receive return signals from the workpiece. The non-destructive inspection apparatus also includes a grip operably connected to the ultrasonic sensor such that the grip and the ultrasonic sensor are movable in concert. The grip is configured to support an operator's palm, such as a majority of the operator's palm, such that force applied to the ultrasonic inspection apparatus by the operator is transferred via the grip to the ultrasonic sensor. The non-destructive inspection system may also include a computer in communication with the non-destructive inspection apparatus to receive information relating to the return signals received by the ultrasonic sensor.

First claim

That which is claimed:

1. A non-destructive inspection apparatus comprising:
an ultrasonic sensor configured to be placed in operable contact with a workpiece, wherein the ultrasonic sensor is configured to emit ultrasonic signals into the workpiece and to receive return signals in response to the ultrasonic signals emitted thereby;
a communication interface configured to communicate with a positioning system to identify a location to be inspected, wherein the communication interface is configured to receive a marker indicative of the location to thereafter be inspected in response to the apparatus being aligned with the marker indicative of the location to be inspected; and
a grip operably connected to the ultrasonic sensor such that the grip and the ultrasonic sensor are movable in concert, wherein the grip is configured to support an operator's palm such that force applied to the ultrasonic inspection apparatus by the operator is transferred via the grip to the ultrasonic sensor.

2. A non-destructive inspection apparatus according to claim 1 further comprising a plurality of grips configured to conform to the palm of different respective operators, wherein the plurality of grips are interchangeably connected to the ultrasonic sensor.

3. A non-destructive inspection apparatus according to claim 1 wherein the grip comprises a gel pad configured to conform to the operator's palm.

4. A non-destructive inspection apparatus according to claim 1 wherein the grip comprises at least one input element configured to be actuated by the operator.

5. A non-destructive inspection apparatus according to claim 1 wherein the communication interface is configured to receive positioning signals that define the location of the non-destructive inspection apparatus.

6. A non-destructive inspection apparatus according to claim 1 further comprising a controller configured to determine that the marker received by the communication interface satisfies a predefined threshold so as to be indicative of the apparatus being aligned with the marker.

7. A non-destructive inspection apparatus according to claim 1 wherein the communication interface is configured to receive, following movement of the apparatus, a sequence of markers indicative of different locations to be inspected.

8. A non-destructive inspection apparatus according to claim 1 wherein the ultrasonic sensor is removably attached to the grip such that the ultrasonic sensor is configured to be disengaged from the grip and inserted into another grip.

9. A non-destructive inspection system comprising:
a non-destructive inspection apparatus comprising:
an ultrasonic sensor configured to be placed in operable contact with a workpiece, wherein the ultrasonic sensor is configured to emit ultrasonic signals into the workpiece and to receive return signals in response to the ultrasonic signals emitted thereby;
a communication interface configured to communicate with a positioning system to identify a location to be inspected, wherein the communication interface is configured to receive a marker indicative of the location to thereafter be inspected in response to the apparatus being aligned with the marker indicative of the location to be inspected; and
a grip operably connected to the ultrasonic sensor such that the grip and the ultrasonic sensor are movable in concert, wherein the grip is configured to support an operator's palm, and wherein the grip comprises at least one input element configured to be actuated by the operator; and

a computer in communication with the non-destructive inspection apparatus so as to receive information relating to the return signals received by the ultrasonic sensor.

10. A non-destructive inspection system according to claim 9 wherein the grip comprises a plurality of input elements configured to be actuated by the operator.

11. A non-destructive inspection system according to claim 9 wherein the non-destructive inspection apparatus further comprises a plurality of grips configured to conform to the palm of different respective operators, wherein the plurality of grips are interchangeably connected to the ultrasonic sensor.

12. A non-destructive inspection system according to claim 9 wherein the grip comprises a gel pad configured to conform to the operator's palm.

13. A non-destructive inspection apparatus according to claim 9 wherein the communication interface is configured to receive positioning signals that define the location of the non-destructive inspection apparatus.

14. A non-destructive inspection system according to claim 9 further comprising a controller configured to determine that the marker received by the communication interface satisfies a predefined threshold so as to be indicative of the apparatus being aligned with the marker.

15. A non-destructive inspection system according to claim 9 wherein the communication interface is configured to receive, following movement of the apparatus, a sequence of markers indicative of different locations to be inspected.

16. A non-destructive inspection system according to claim 9 wherein the ultrasonic sensor is removably attached to the grip such that the ultrasonic sensor is configured to be disengaged from the grip and inserted into another grip.

17. A method for non-destructively inspecting a workpiece comprising:
placing an ultrasonic sensor of a non-destructive inspection apparatus in operable contact with the workpiece;
supporting an operator's palm with a grip that is operably connected to the ultrasonic sensor;
communicating with a positioning system to identify a location to be inspected, wherein communicating with the positioning system comprises receiving a marker indicative of the location to thereafter be inspected in response to the apparatus being aligned with the marker indicative of the location to be inspected;
emitting ultrasonic signals from the ultrasonic sensor into the workpiece at the location to be inspected;
receiving return signals in response to the ultrasonic signals emitted thereby; and
moving the grip and the ultrasonic sensor in concert in response to force applied to the grip by the operator is transferred via the grip to the ultrasonic sensor.

18. A method according to claim 17 further comprising replacing the grip with another grip configured to conform to the palm of a different operator.

19. A method according to claim 17 wherein the grip comprises an input element, and wherein the method further comprises receiving an indication from the input element regarding actuation of the input element by the operator.

20. A method according to claim 17 wherein communicating with the positioning system comprises receiving positioning signals that define the location of the non-destructive inspection apparatus.

21. A method according to claim 17 further comprising determining that the marker that is received satisfies a predefined threshold so as to be indicative of the apparatus being aligned with the marker.

22. A method according to claim 17 further comprising receiving, following movement of the apparatus, a sequence of markers indicative of different locations to be inspected.

23. A method according to claim 17 further comprising disengaging the ultrasonic sensor from the grip following receipt of the return signals and inserting the ultrasonic sensor into another grip.
