Latest Patents

Itzke's latest patents showcase his ingenuity and technical expertise. The first patent is a **current measuring device with Hall sensors** designed to generate an output current proportional to the current being measured. This device incorporates at least two Hall sensors strategically arranged on a circular path and oriented towards a center point. Its innovative design features an adding circuit that sums the measurement signals from the Hall sensors, along with a subtracting circuit to eliminate any offsets. The device is powered by a voltage-controlled current source and utilizes a current supply featuring a toroidal coil with a paramagnetic or diamagnetic core, complemented by a DC/DC converter for the Hall sensors.

The second patent, titled **method for measuring a current and current-measuring device**, involves a unique arrangement of flux-gate field sensors and Hall sensors. These sensors are symmetrically positioned on separate circumferential paths, allowing adjacent placement to capitalize on their respective sensitivities. This arrangement increases measurement accuracy, as the flux-gate sensors have a sensitivity that is 5 to 20 times greater than that of the Hall sensors. This method not only determines current intensity based on sensor data but also utilizes strategic evaluations to enhance measurement reliability.
