STMicroelectronics Assigned Patent

STMicroelectronics, Inc., Coppell, TX, and STMicroelectronics S.r.l., Agrate Brianza, Italy, has been assigned a patent (11756582) developed by Pulici, Paolo, Lainate, Italy, Hogg, Dennis, Laguna Hills, CA, Bartolini, Michele, Carpiano, Italy, Sentieri, Enrico, Lodi, Italy, and Mammei, Enrico, Vittuone, Italy, for “system and method for disk drive fly height measurement.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system for determining a fly height includes a first head of a disk drive, a second head of the disk drive, a capacitive sensor circuit coupled to the first head and the second head, and a logic device coupled to the capacitive sensor circuit. The capacitive sensor circuit is configured to measure a first capacitance between the first head and the first disk, remove noise from the first capacitance using a second capacitance between the second head and the second disk, and based thereon determine a corrected first capacitance. The logic device is configured to determine the fly height between the first head and the first disk using the corrected first capacitance.”

The patent application was filed on 2022-05-11 (17/742202).
