Title: Innovations by Ali Piranfar in Data Integrity Assurance

Introduction

Ali Piranfar is an accomplished inventor based in Boise, ID (US). He has made significant contributions to the field of data integrity, particularly in disk drive technology. His innovative approach addresses critical issues related to power failures in disk drives.

Latest Patents

Piranfar holds a patent for "Data integrity assurance in a disk drive upon a power failure." This invention involves a disk drive package that includes read/write circuits, a disk drive mechanism, and a microprocessor. The microprocessor is designed with a dedicated function input and an interrupt input. The dedicated function input is accessible through an external connector, while the interrupt input has no direct external access. The microprocessor examines the dedicated function input upon power-up to determine if it has been enabled. The disk drive package is enhanced with a circuit that connects the dedicated function input to the interrupt input. A power supply provides a power fail imminent signal to the dedicated function input, which triggers an interrupt in the disk drive's operation. This ensures that any write to disk in progress is completed before a power failure occurs.

Career Highlights

Piranfar is currently employed at Hewlett-Packard Company, where he continues to innovate and develop new technologies. His work has had a significant impact on the reliability and performance of disk drives in various applications.
