Latest Patents
One of his latest patents is focused on fault location methods and apparatus using current pulse injection. This invention involves a probe designed to sense the direction of flow of an injected current pulse along a conductor of a circuit under test. The probe is linked to an Automated Test Equipment (ATE), which triggers the injection of the pulse during a test sequence. This process helps identify faulty components connected to a circuit node. The probe can also function independently, injecting an approximately triangular-waveform current pulse that has a steep rising edge and a less steep falling edge. This design induces a voltage pulse that is asymmetric about the zero voltage level, allowing for the discrimination of the direction of current flow. Additionally, the probe may feature a single current injection contact positioned between the limbs of a bifurcated core for the pick-up coil.
