Abstract: A method for screeding an uncured concrete surface includes providing a screeding machine having a screed head assembly movable over the concrete surface. A pair of elevation sensors disposed at opposite ends of the screed head assembly sense an elevation of the respective end of the screed head assembly. An angle sensor disposed at the screed head assembly senses a pitch angle and/or a roll angle of the screed head assembly. A gyroscope sensor disposed at the screed head assembly senses rotational velocity of the screed head assembly about a lateral axis and/or a longitudinal axis of the screed head assembly. A control determines pitch angle and/or roll angle of the screed head assembly. The control controls the screed head assembly based on the signals from one or both of the elevation sensors and the determined pitch and/or roll angles.

Abstract: A portable vehicle barrier is transportable to a desired location, unfolded from a compact transport configuration and deployed to provide an effective vehicle barrier that can be used temporarily and then refolded into the compact transport configuration and transported to a remote location for utilization or storage. The vehicle barrier is formed with a central base having front and rear sections that are pivotally hinged to the central base. A barrier member can be selectively activated to rise into an active position and restrain the passage of vehicles. An impact into the barrier member causes the central base to tip in order to drive pointed teeth into the tires of the vehicle and into the underlying road surface and stop the impacting vehicle. The front and rear sections have vertical bars that move into a nesting horizontal position when the front and rear sections are pivoted into the transport position.

Abstract: A selectively frictionally engaged hole cover for a bore hole cored from a paved surface that includes a cover plate configured to cover the bore hole and support vehicular traffic. An engagement mechanism is attached to the cover plate and extends down into the bore hole. The engagement mechanism is configured to be actuated by a user torque input that causes an engagement plate selectively shiftable relative to the cover plate to thereby shift an engagement member along a sloped wall and thus radially outwardly or inwardly, causing the engagement mechanism to selectively engage or disengage the wall of the bore hole. When the engagement member is in frictional contact with the hole, unintentional extraction of the engagement mechanism is prevented. The selectively frictionally engaged hole cover effectively provides a temporary cover for a bore hole in a road, parking lot, or other paved surface.
