Abstract

Actuator bracket having a sensor is disclosed. An example apparatus includes a bracket having a first side and a second side opposite the first side. The first side is to couple to a first surface of an actuator. The second side is to couple to a controller. The apparatus also includes a first sensor coupled to the first side of the bracket. When the bracket is coupled to the first surface of the actuator, the first sensor is adjacent the first surface to measure a characteristic of the first surface of the actuator.

First claim

What is claimed is:

1. An apparatus comprising:
a bracket having a first side and a second side opposite the first side, the first side to directly couple to a first surface of an actuator, the second side to directly couple to a controller, wherein the first side of the bracket includes a plurality of cavities defined by a plurality of ribs, the ribs having a uniform height defining a plane of the first side; and
a first sensor coupled to the first side of the bracket, wherein, when the bracket is coupled to the first surface of the actuator, the first sensor is adjacent the first surface to measure a characteristic of the first surface of the actuator, wherein the first sensor is disposed within one of the cavities between the plane of the first side and the second side.

2. The apparatus of claim 1 , wherein the characteristic of the first surface of the actuator indicates a characteristic of at least one of a coupling of the bracket and the actuator, a coupling of a controller and the bracket, a yoke of the actuator, a yoke lock nut, and tubing between the controller and the actuator.

3. The apparatus of claim 1 , wherein the first sensor is coupled to the bracket between at least two of the ribs and is recessed from an outer edge of the ribs to enclose the first sensor by the at least two of the ribs, the first side of the bracket, and the first surface of the actuator.

4. The apparatus of claim 3 , wherein the first sensor is enclosed by the at least two ribs, the first side of the bracket, and the first surface of the actuator to prevent the first sensor from being damaged or dislodged.

5. The apparatus of claim 1 , wherein an outer edge of at least one of the ribs defines a groove to fixedly receive a wire coupled to the first sensor via potting, the groove to prevent the wire from being damaged when the bracket is coupled to the actuator.

6. The apparatus of claim 5 , wherein the wire is disposed between the plane and a surface of the groove of the rib.

7. The apparatus of claim 1 , wherein the bracket defines an aperture that is to receive a wire extending between the first sensor and a receptacle of the controller to operatively couple the first sensor and the controller.

8. The apparatus of claim 1 , wherein the first sensor is an acoustic emission sensor, a force gauge, or a strain gauge.

9. The apparatus of claim 1 , further comprising a second sensor coupled to the first side of the bracket and spaced apart from the first sensor, wherein a characteristic measured by the second sensor and the characteristic measured by the first sensor are compared to identify a characteristic of at least one of a coupling of the bracket and the actuator, a coupling of a controller and the bracket, a yoke of the actuator, a yoke lock nut, and tubing between the controller and the actuator.

10. The apparatus of claim 1 , further comprising a second sensor that is to couple to a second surface of the actuator different than the first surface, the second sensor to measure a characteristic of the second surface of the actuator.

11. The apparatus of claim 10 , wherein, when the bracket is coupled to the controller and the actuator, the first sensor and the second sensor are operatively coupled to the controller to enable the characteristic of the coupling to be compared to the characteristic of the second surface.

12. The apparatus of claim 1 , wherein the first sensor is an accelerometer to measure vibrations of the actuator to determine degradation of the actuator or a coupling of the bracket to the actuator.

13. The apparatus of claim 1 , wherein the characteristic is indicative of a degree to which the bracket is rigidly coupled to the actuator.

14. The apparatus of claim 1 , wherein the characteristic includes at least one of stress, strain, acceleration, vibration, and acoustic emissions.

15. The apparatus of claim 1 , wherein the characteristic is indicative of a fatigue of one or more fasteners of the bracket.

16. The apparatus of claim 1 , wherein the characteristic is indicative of a defect of the bracket.

17. The apparatus of claim 1 , wherein the first sensor is positioned immediately adjacent a coupling of the bracket and the actuator to measure a characteristic of the coupling.

18. The apparatus of claim 1 , wherein the first sensor is disposed between the plane and the second side to protect the sensor from damage.

19. An apparatus comprising:
means for coupling a controller to a surface of an actuator, wherein a first side of the means for coupling includes a plurality of cavities defined by a plurality of ribs, the ribs having a uniform height defining a plane of the first side; and
means for sensing a characteristic coupled to the means for coupling, wherein, when the means for coupling is coupled to the actuator, the means for sensing is adjacent the surface to measure a characteristic of the means for coupling, wherein the means for sensing is disposed within one of the cavities between the plane of the first side and a second side of the means for coupling.

20. The apparatus of claim 19 , wherein the means for coupling includes means for enabling a wire to extend between the means for sensing and the controller to operatively couple the means for sensing and the controller.
