  • Three-dimensional surface measuring scanner
    Patent number: 8416427
    Abstract: There is described a scanner having a frame with a support, two lasers attached to the frame and two optical sensors attached to the frame, the lasers and optical sensors being positioned and oriented to reduce shadowing effects for the cameras and for the laser lines while covering close to 100% of the surface of an object to be imaged and reducing the scanning time.
    Type: Grant

  • Sensor feedback control for automated bucket loading
    Patent number: 5941921
    Abstract: Automated bucking loading is achieved through the use of sensor feedback provided by pressure and extension sensors on hydraulic cylinder(s) to control the trajectory of the bucket to be loaded by a computer algorithm. Additional sensors may be used to provide further control of the loading cycle and of the vehicle operation. The structure and steps can be integrated with existing machinery or used on new loaders equipped with suitable control interfaces capable of taking computerized control of the vehicle's actions.
