Abstract: An ultrasonic inspection apparatus for an ultrasonic inspection system for inspecting a railway track, the ultrasonic inspection system for attaching to a bogie for pulling over the railway track, comprising a framework for attaching to the bogie, a sled for inspecting a rail, the sled carrying an array of ultrasonic transducers for detecting flaws in the rail, the system further comprising a water subsystem for ensuring fluid coupling between the sled and the rail, automatic lateral position rectification subsystem for keeping the sleds centered over the railway tracks as the train moves along the track, the ultrasonic transducers in data communication with a computing system in a wagon over the bogie for analyzing and mapping the flaws in the rail, wherein at least one pair of ultrasonic transducers is mounted in the same housing thereby shortening the length of the sled to be irrigated.

Abstract: Aspects of the invention may be related to a computer system and a computerized method of controlling a marine vessel. Embodiments may include: receiving, by a controller, a position of the marine vessel from a positioning system; receiving, by the controller, geographical data, from at least one database, the geographical data may include at least a map of seabed depths; receiving, by the controller, a heading direction and speed of the marine vessel; calculating, by the controller, a safety zone ahead of the marine vessel based on the position, the heading direction and the speed of the marine vessel; identifying a location of a critical seabed depth inside the safety zone based on the received, the geographical data; and changing, by the controller, a state of a propelling unit of the marine vessel when a critical seabed depth was identified inside the safety zone.
