Latest Patents

Among his notable patents, two standout inventions exemplify his expertise:

1. **Data storage device on-line adapting disturbance observer filter** - This patent discloses a data storage device featuring a head actuated over a disk with tracks defined by servo sectors. The invention generates a location of the head based on the servo sectors and produces a position error signal (PES), which indicates the difference between the target and measured locations of the head. The actuator control signal (ACS) is created in response to the PES, while a disturbance compensation signal (DCS) enhances performance by factoring in the PES and ACS. The DCS undergoes filtering through a series of band-pass filters, with a peak detection filter detecting frequency peaks to adjust the disturbance observer filter accordingly.

2. **Disk drive compensating for microactuator gain variations** - This patent describes a disk drive that consists of a head and a disk surface containing servo information. It incorporates a dual-stage actuator servo loop that employs a voice coil motor (VCM) and a microactuator to effectively control the head's movement across the disk surface. A position error signal (PES) is generated based on servo information, leading to a control signal that compensates for microactuator gain variations, ultimately enhancing the efficiency of disk operations.
