  • Publication number: 20260226953
    Abstract: At least one, preferably at least two bistable magnetic elements (1), which are adapted for magnetization reversal in the dynamic magnetic field of the reading device (2), are positioned in the material wear zone. The material loss is accompanied by a decrease in the number of detected bistable magnetic elements (1). The presence of the bistable magnetic element (1) is detected by the reading device (2) based on the evaluation of the magnetization reversal response of the bistable magnetic element (1), when typical, narrow local maxima (e) are searched for in the received signal. Advantageously, a magnetic field with triangular shape is used, which has essentially a linear increase in excitation, which conveniently separates the maxima of several bistable magnetic elements (1). The reading device (2) can be a permanent part of the system or it can be a portable device that is used during a service or inspection of the particular device.

  • Patent number: 12688378
    Abstract: A method for identifying an identification (ID) tag that includes at least one magnetically bistable element. The method comprises one or more steps, including transmitting, via an excitation antenna, an excitation signal to the magnetically bistable element. An additional step includes receiving, via a pick-up antenna, a response signal generated by the bistable element. An additional step includes analyzing the response signal to identify at least two peaks in the response signal. A further step includes generating an identification code based on the two peaks, with the identification code being representative of an identity of the bistable element.

  • Publication number: 20250224258
    Abstract: The system for physical quantity measurement and/or for position measurement with a bistable magnetic wire (1), which comprises excitation element (2) for creating of magnetic field and a sensing element (3). Within the range of the magnetic field of the excitation element (2), a bistable magnetic wire (1) is placed, which has a first end (11) and an oppositely placed second end (12). The bistable magnetic wire (1) is adjusted for magnetization by a single Barkhausen jump from the first end (11) to the second end (12) or vice versa, wherein the excitation element (2) and bistable magnetic wire (1) are placed in a mutual position with an asymmetric magnetic field with respect to the bistable magnetic wire (1), where the size of the magnetic field excited by the excitation element (2) at the first end (11) is different from the size of the magnetic field excited by the excitation element (2) at the second end (12).
