According to some embodiments, a system for determining a characteristic of a bulk lading of a railcar comprises a sensor (e.g., infrared, radio, electrical, optical, etc.) operable to determine a characteristic of a bulk lading; a controller communicably coupled to the sensor and configured to control sensor operations; and a display communicably coupled to the sensor and configured to display a representation of the determined characteristic of the bulk lading. In particular embodiments, the sensor may detect a moisture content of the bulk lading or a foreign substance in the bulk lading. At least one of the sensor, the controller, and the display may comprise a power source. At least one of the controller and the display may be wirelessly coupled to the sensor.

The invention is directed to a non-destructive method of detecting whether a coating or deposit (30, 34) of (a) SiO.sub.xCy or SiN.sub.xC.sub.y and/or (b) of SiO.sub.x is present on or near a surface of an article (12), such as a disposable thermoplastic medical article. The method includes impinging infrared light (216) having a wave number in at least a portion of a desired range onto at least a first surface being examined for the presence of the one or more coatings or deposits. At least a portion (224) of the infrared light impinged on the first surface is collected (at 222) and the response output, which may include for example the maximum intensity and/or peak area of the collected infrared light at an infrared spectroscopy peak, is used to indicate the presence of the one or more coatings or deposits.

This invention comprises a system and a method for inspecting the inside of delayed petroleum coking vessels to identify deformations, detect and determine the severity of other defects, and visually observe the inside of the inspected vessel.

An apparatus (1) for optical inspection of parisons (2) intended to be blow moulded to form containers, where the parisons (2) are made of plastic material and have a side wall (201), a closing bottom and a mouth end (202) having on its outside surface a screw thread (205) and an identification code (207) in relief, comprises: a conveyor (3) equipped with a plurality of receiving elements (4) configured to transport corresponding parisons (2) along a predetermined path where, in an inspection station located along the predetermined path, each parison (2) is positioned with its axis (208) aligned with a longitudinal reference axis; a stationary camera (7) mounted in such a way that its viewing axis (8) coincides with the longitudinal reference axis in order to see the interior of the parison (2); an illuminator (9) positioned around the viewing axis (8) of the camera (7) in order to irradiate the outside surface of the mouth end (202) of the parison (2) positioned in the inspection station. The camera (7) has a wide-angle lens and is configured to capture an image of an inside surface of the mouth end (202) of the parison (2) positioned in the inspection station, representing the screw thread (205) and the identification code (207) of the parison (2), shown in transparency.

An inspection device for use in a fluid container includes a hull adapted to be received in the fluid container and a control mechanism carried by the hull.
