Latest Patents

Among his latest patents is a system for adjusting a magnetic sensor to detect the presence of ferrous objects. This proximity detector utilizes a Hall-effect flux sensor positioned between two magnets. The opposing magnetic fields create a null flux field at the sensor's sensing plane. When a ferrous object comes close, it disrupts this null point, allowing the sensor to generate a signal indicating the object's presence. Another significant patent is for a magnetic accelerometer designed to detect sharp lateral rocking movements in an unbalanced washing machine tub. This device features a fixed and a movable magnet that respond to vibration forces. When the vibrations exceed a certain threshold, the movable magnet activates a miniature switch, signaling an alarm condition.
