Latest Patents

Wolfe's latest patents include innovative systems designed to improve fault detection and proximity sensing in magnetic disk drives. One of his notable inventions is the "Flex over suspension fault detection under a write gate for magnetic disk drives." This system employs a flex over suspension fault comparator that compares a predetermined reference threshold to a positive delta of a disk drive write head data stream, providing a positive or negative fault indication. Additionally, a max/min buffer detects the polarity of the read/write head, applying a positive buffered delta to the fault comparator. A transition-free window detector triggers the fault comparator to output a fault indication when a transition-free window of zero-value data bits is detected, ensuring accurate fault validation.

Another significant patent is the "Proximity sensing system," which is a data storage system that detects the location of a head relative to magnetic media. This system includes arms, a preamplifier circuit, and a proximity sensing system that transmits input sense signals and processes them to determine the head's location accurately.
