Publication number: 20220170215Abstract: A device for fixing and positioning a rail monitoring element on a rail web of a rail having a rail foot, the rail web, and a rail head, includes a clamping device which can be fastened to the rail. A pressing ram is for pressing the rail monitoring element against the rail web. The pressing ram can be pressed against the rail web when the device is in the mounted state by means of force generated by a force element. A holder is for receiving the force element.Type: ApplicationFiled: February 16, 2022Publication date: June 2, 2022Applicant: Thales Management & Services Deutschland GmbHInventors: Kassen Oldewurtel, Kai Schicker

Patent number: 11345376Abstract: A method for assembling a strain gauge arrangement for an axle counter, includes: a strain sensor element; a carrier, to which the strain sensor element is fastened; and a railroad track structure to be monitored. When the carrier is fastened to the structure at least a part of it is kept in an elastically deformed state. The carrier is embodied with a first carrier piece opposing a second carrier piece. The strain sensor element is fastened to the first carrier piece with a first fixing point, to the second carrier piece with a second fixing point, and to neither the first nor the second carrier piece with a central section between the fixing points. At least the part of the carrier is elastically braced by means of a bracing element for when adhesively bonding to the structure to be monitored. Thereafter the bracing element is removed.Type: GrantFiled: January 22, 2021Date of Patent: May 31, 2022Assignee: Thales Management & Services Deutschland GmbHInventors: Kai Schicker, Kassen Oldewurtel, Rainer Klemm, Florian Muschaweckh, Lars Hoffmann

Patent number: 10926782Abstract: A strain gauge arrangement for an axle counter has a strain sensor element, a carrier and a railway line structure that is to be monitored. At least one part of the carrier is maintained in an elastically deformed state by the structure when the carrier is secured to the structure. The carrier is formed from a first carrier piece and a second carrier piece, which lie opposite one another at a distance from one another. The strain sensor element has one first fixing point fixed to the first carrier piece, and one second fixing point fixed to the second carrier piece, and a middle section mounted between the fixing points which are not fixed to the first or second carrier piece. The strain gauge arrangement is simple to handle and a drop can be reliably detected and a strain state of the strain sensor element can be predetermined more easily.Type: GrantFiled: March 21, 2020Date of Patent: February 23, 2021Assignee: THALES MANAGEMENT & SERVICES DEUTSCHLAND GMBHInventors: Kai Schicker, Kassen Oldewurtel, Rainer Klemm, Florian Muschaweckh, Lars Hoffmann

Patent number: 10858021Abstract: A method for determining the speed of a rail-bound vehicle, includes the following method steps: detection of a reference element, wherein the first detection device generates a first detection signal when the reference element passes the first detection device; detection of the reference element, wherein the second detection device generates a second detection signal when the reference element passes the second detection device; conversion of the detection signals into digital detection pulses; determining the time difference between the two detection pulses; wherein an XOR signal is generated in an XOR gate by linking the first and the second detection pulse using an XOR logic; and the duration of the XOR signal is determined; and wherein the time difference between the two detection pulses is determined by halving the duration of the XOR signal. The speed can be measured with higher accuracy when using an existing infrastructure without additional assembly work.Type: GrantFiled: March 14, 2018Date of Patent: December 8, 2020Assignee: THALES MANAGEMENT & SERVICES DEUTSCHLAND GMBHInventor: Kassen Oldewurtel
