Patent ID: 7575395

Claim:
A device for deploying a sensor from a moving construction vehicle, the sensor being used to sense a property of a material mat having an upper surface, the deployment device comprising: a positioning mechanism connected with the vehicle and connectable with the sensor, the mechanism being configured to displace the sensor between first and second vertical positions with respect to the material mat as the vehicle displaces with respect to the mat, the first sensor position being spaced a substantial distance above the mat upper surface and the second sensor position being located one of proximal to the mat surface and on the mat surface, the sensor being able to sense the material property when disposed in the second position, the positioning mechanism including a flexible connective member having a first end connectable with the sensor and an opposing second end and a rotary actuator connected with the vehicle and having a rotatable shaft, the member second end being connected with the shaft such that rotation of the shaft displaces the sensor between the first and second sensor positions.
