Latest Patents

One of Dettmann's latest patents is a system for writing magnetic scales. This invention relates to a system for pulse magnetizing high-precision magnetic scales. The system comprises a shaped current conductor and a pulse current source that includes a capacitor bank, a transfer switch, and a control unit. The compact setup of the system is crucial for achieving a power circuit with low resistance, allowing for high pulse currents at supply voltages below 60 V. The transfer switch is designed as an H bridge with four switches containing equal numbers of MOS transistors connected in parallel. The short pulse times achieved using the MOS transistors enable the use of shaped current conductors, producing magnetized areas with very high precision. This inventive system provides a means for saving components, electric power, and time by a factor of up to 100.

Another significant patent is a length measurement system featuring at least one magnetic measuring rod. In this system, the direction of magnetization lies in the plane of the cross-section, which is perpendicular to the direction of measurement and forms a magnetization pattern. As one advances in the direction of measurement, the magnetization pattern rotates in relation to the starting end of the measuring rod. This results in a magnetic field whose direction continuously rotates as one moves along the measurement path. By utilizing at least one magnetic field sensor that responds to the direction of the magnetic field, the prevailing field angle for each position can be determined and clearly assigned to various positions within the length measurement system.
