Abstract

A method of actuating a wireless sensor of road construction equipment. A bracket is secured to the road construction equipment that has a magnet and is able to receive a wireless sensor. An actuator is disposed within the housing of the wireless sensor that reacts to the magnetic field created by the magnet such that when the wireless sensor is attached to the bracket the sensor is operable and when detached from the bracket no longer operates.

Claims

1. A method of actuating a wireless sensor of road construction equipment steps comprising:

providing a road construction machine;

securing a bracket to the machine;

attaching a magnet to the bracket in spaced relation to an attachment section of the bracket;

attaching a wireless sensor to the attachment section of the bracket; and

wherein the magnet actuates an actuator of the wireless sensor when the wireless sensor is attached to the bracket.

2. The method of claim 1 wherein the road machine is a road paver.

3. The method of claim 1 wherein the magnet is fixed to the bracket.

4. The method of claim 1 wherein the wireless sensor is a laser sensor.

5. The method of claim 1 wherein the wireless sensor is a sonic sensor.

6. The method of claim 1 wherein the wireless sensor has a housing that encloses a battery.

7. The method of claim 6 wherein the actuator of the wireless sensor is enclosed with the housing of the wireless sensor.

8. The method of claim 7 wherein the actuator is a reed switch in electric communication with the battery.

9. The method of claim 1 further comprising the step of removing the wireless sensor from the bracket to deactivate the wireless sensor.
