A sensor system for a host vehicle may detect whether another in-path vehicle is turning. The programmable clock generator includes first pulse generating unit and a pulse multiplier. The input impedance is smaller than the output impedance in the current-mode low-order filter. The frame has a hopper for receiving wet concrete and a curb shaping portion that shapes the wet concrete into a curb shape. When the obstacle detector detects the obstacle, the control unit determines whether or not the obstacle is present within a monitoring region, and when the obstacle is present inside the monitoring region, the control unit stops the electric motor for swiveling. Data is stored to a database and aggregated to generate trending information.
