Abstract: A steering system for steering a heavy haul trailer dolly comprising a turntable mounted on the dolly for connecting to another trailer unit. The dolly comprising a main frame, a wheel group mounted to the main frame, and a pivot frame mounted to the main frame between the turntable and the wheel group. A counter-steering linkage connects the pivot frame and the turntable. Hydraulic cylinders connect the pivot frame and the wheel group. To automatically steer the dolly, the hydraulic cylinders are locked in length. Rotation of the turntable in one direction causes the pivot frame and the wheel group to rotate in the opposite direction. To steer the dolly directly, the hydraulic cylinders are operated to extend and retract, pushing and pulling against the pivot frame and turntable to rotate the wheel group.

Abstract: An adaptable wind blade clamp for securely fastening and supporting a wind turbine blade during transportation. Walking beams are pivotably coupled to inner sides of the wind blade clamp jaws, and pads which contact the wind turbine are pivotably coupled to ends of the walking beams, resulting in a wind blade clamp which easily adjusts to the varying cross-sectional profiles of the wind turbine blade along its length. The wind blade clamp is optionally provided with an edge walking beam and edge pads to support and protect the leading edge of the wind turbine blade.

Abstract: An improved articulated heavy haul trailer combination comprises a trailing accessory vehicle such as a booster coupled to a main trailer by a coupling. The coupling includes a horizontal hinge, a vertical hinge that allows the trailing accessory vehicle to yaw in a horizontal plane, a spreader extending between the hinges and a hydraulic piston and cylinder. A turn sensor mounted on said combination detects yawing, and a controller reduces the piston and cylinder's downward biasing force on the coupling.

Abstract: Video clips and images captured by one device (e.g., a camera) are associated with one or more synchronization labels such as synchronization device labels and synchronization time labels determined by the device. Synchronization device labels can be used to identify devices that are synchronized. Synchronization time labels indicate relative timing between the devices that are synchronized. When a device is on, it transmits a synchronization signal and receives another synchronization signal transmitted by another device in response to receiving the synchronization signal it has transmitted. The two devices each calculate a synchronization device label and a synchronization time label using the synchronization signals and associate the synchronization device label and synchronization time label with video frames and images captured. Video clips and images can subsequently be aligned using the associated synchronization device labels and the synchronization time labels.
