Publication number: 20250229814Abstract: A method and apparatus to detect breaks in tracks and/or detect the presence of a vehicle, such as a train, in a monitored section of the track or rail. Embodiments of the present invention measure the change in track inductance associated with a track or rail break. Electrical shunts are connected between the rails at spaced-apart intervals (for example a shunt can be placed every mile). At least two different frequencies of alternating current are generated and fed into the segments of rail (for example at or near a mid-point between the shunts). If a rail break occurs, the total inductance of the rail at that segment will change. Using two or more frequencies allows a rail break to be differentiated from environmental rail-to-rail and rail-to-earth leakage.Type: ApplicationFiled: April 2, 2025Publication date: July 17, 2025Applicant: Athena Industrial Technologies Inc.Inventor: Paul D.

Publication number: 20220234632Abstract: A method and apparatus to detect breaks in tracks and/or detect the presence of a vehicle, which can include for example a train, in a monitored section of the track or rail. Embodiments of the present invention measure the change in amplitude and/or phase angles. Electrical shunts are connected between the rails at spaced-apart intervals. At least two different frequencies of alternating current are generated and fed into the segments of rail (for example at or near a mid-point between the shunts). If a rail break occurs, the total inductance of the rail at that segment will change.

Patent number: 9030195Abstract: An apparatus is provided for sensing anomalies in a long electrically conductive object to be inspected. The object may be a pipeline, or other hollow tube. The apparatus may have a magnetic field generator, and an array of sensors spaced about the field generator. As relative motion in the longitudinal direction occurs between the apparatus and the object to be inspected, the moving magnetic field, or flux, passed from the field generator into the object to be inspected may tend to cause eddy currents to flow in the object. The sensors may be spaced both axially and circumferentially to permit variation in magnetic flux, or eddy current divergence, to be sensed as a function of either or both of axial position relative to the wave front of the magnetic field (or, effectively equivalently any other known datum such as the radial plane of the midpoint of the field generator), and circumferential position about the periphery of the apparatus as measured from an angular datum.Type: GrantFiled: December 20, 2007Date of Patent: May 12, 2015Assignee: Athena Industrial Technologies, Inc.Inventor: Paul D.

Patent number: 8463548Abstract: An apparatus is provided for assessing the location of a drill bit underground. The apparatus includes an acoustic sound generator that is driven by the drilling mud supplied to the drill bit. The sound generator a characteristic string of pulses, which may be termed a signature or key. The key is repeated over and over. Monitors (i.e., sensors) at the surface listen for this key. The key is distorted by the inconstant angular velocity of the drill bit. Thus the observed data do not precisely match the key. On the basis of numerical algorithms, a digitally revised reference signal or key, is identified to map the known reference key onto the best fitting observed data. The correction factors are then applied to map the modified reference key onto the data observed at other sensors of an array of sensors mounted on the surface.Type: GrantFiled: July 23, 2008Date of Patent: June 11, 2013Assignee: Athena Industrial Technologies, Inc.Inventor: Paul D.

Patent number: 8274279Abstract: An apparatus and method are disclosed for detecting flaws in electrically conductive materials by observing properties of the back-EMF of the eddy current field generated by driving magnetic flux through the object to be examined. The input signal may include sweeps at several frequencies, and may do so at one time under the principle of wave superposition. The sectorial observations of eddy currents summations may be compared to a known datum for a defect free material, the presence of anomalies in eddy field back EMF divergence tending to provide an indication of an irregularity in the underlying eddy field, and hence in the underlying material itself. The portable unit may have a number of different configurations depending on the nature of the object to be examined, be it a flat or large radius plate, a flange, a rail, or some other structural element.Type: GrantFiled: October 16, 2007Date of Patent: September 25, 2012Assignee: Athena Industrial Technologies, Inc.Inventor: Paul D.
