Abstract: A mounting device may include a top plate including a cone-shaped center portion, a flange coupled to the cone-shaped center portion, a number of apertures defined in the flange, and a number of fasteners engaged with the apertures to couple the top plate to a surface of a structure. The flange seals a bottom side of the top plate to the surface of the structure. The flange includes a seal coupled to the bottom of the flange. The cone-shaped center portion has a convex paraboloid shape. The flange includes at least one surface that is parallel to a surface of the structure, and a transition between the cone-shaped center portion and the flange forms an angle. The top plate has a diameter sufficient to displace a load greater than 50 pounds over the surface of the structure.

Abstract: The present invention is directed to a system and method for verifying roll roundness of a cylindrical object and more particularly for verifying the roundness of rolls of papers used for newspaper printing. According to the present invention, a roll rotator is configured with a plurality of ultrasonic sensors, which are activated when a roll of paper is lifted and rotated by the roll rotator. The roll of paper is rotated an entire revolution and a plurality of distance measurements are taken at each sensor. As the readings are taken, a filter algorithm may be applied to remove values that are too far out of range, such as values which are representative of a torn wrapper or other defects in the covering surface of the roll. Once the readings have been taken, an average of the readings is calculated and the roundness algorithm compares each reading with the average for each of the sensors.

Abstract: The present invention relates to a security device for fixing to a surface to allow relative movement of the device and the surface to be detected, and a connector for such a device.
