Abstract: A road surface scanning device and method for scanning a section of road in order to acquire road surface data, which in turn can be used to create a mathematical model of the road. In one embodiment, the road surface scanning device includes a frame, a carriage movably mounted to the frame, a scanner movably mounted to the carriage, and a pair of electric actuators that can move the scanner across the road surface. Information from adjacent scanner passes are electronically stitched together and, in a similar manner, information from adjacent surface segments are electronically joined to form a mathematical model of the road. Various techniques can then be used to process the road surface data and prepare it for use by other software applications.

Abstract: In a vehicle with a radio, a transmission, a brake, a throttle, a vehicle speed and a power antenna, a method of controlling the power antenna comprising the steps of: (a) determining whether the radio is in an on state; (b) determining if the transmission is one of: (i) in a neutral state and (ii) in an unengaged state; (c) determining if the brake is in an off state; (d) determining if the throttle is in an idle state; (e) determining if the vehicle speed is below a predetermined threshold; and (f) responsive to the determinations, if the radio is in the on state, the transmission is in one of: (i) the neutral state and (ii) the unengaged state, the brake is in the off state, the throttle is in the idle state and the speed is below the predetermined threshold, automatically retracting the power antenna, thereby preventing possible damage to the antenna by the automatic car wash.
