Abstract: This disclosure relates to the inspection of train wheels while mounted on a train that is moving on a railroad track. A magnetostrictive EMAT transducer is built using an RF Coil, a static biasing magnetic field, and a strip of highly magnetostrictive material. This magnetostrictive EMAT transducer is subsequently attached to a rail on the track so the wheel tread of the moving train can contact and apply downward pressure on the magnetostrictive EMAT transducer. A mechanism under the transducer provides enough counterforce to pressure-couple the transducer with the tread of the wheel. Once the transducer is ultrasonically coupled with the wheel, an ultrasonic instrument sends a pulse to the transducer generating a Shear Horizontal wave that travels circumferentially following the tread body. The Shear Horizontal wave generated with this magnetostrictive strip EMAT transducer penetrates deep into the wheel tread and permits detection of both surface and internal defects.

Abstract: A water level detection method via video recognition, includes steps of obtaining an image of a water level gauge from a camera; wherein the water level gauge includes multiple two-dimensional barcodes; and determining a water level according to the two-dimensional barcodes. When a body of water partly covers the water level gauge, the body of water would cover some of the two-dimensional barcodes, leaving the rest of visible two-dimensional barcodes corresponding to the water level. When the water is clear, the two-dimensional barcodes underwater would be visible yet at the same time indecipherable due to distorted barcode scales. This way, the present invention is able to avoid accidentally counting two-dimensional barcodes underwater, and thus more accurately and robustly detect water levels.
