Patent number: 9251556Abstract: The present invention provides a display control method and system, and a display device. The method includes acquiring a status value of a display buffer; comparing the status value of the display buffer with a preset warning value of the display buffer; and adjusting a value of a depth of outstanding bus commands according to a comparison result. In the embodiments of the present invention, a status value of the display buffer is compared with a preset warning value of the display buffer, where the status value of the display buffer reflects a change to a current load; it may be determined whether a status value of the display buffer corresponding to the current load is normal according to a comparison result; and a value of a depth of outstanding bus commands is adjusted accordingly, effectively resolve a data real-timeness issue, and ensure that an entire system efficiently runs.Type: GrantFiled: May 24, 2013Date of Patent: February 2, 2016Assignee: Huawei Technologies Co., Ltd.Inventors: Zhe Li, Jun Huang, Jiayin Lu, Jianbo He

Patent number: 6791786Abstract: An actuator control system for a two-stage actuator system of a disc drive has a first, or primary, stage actuator consisting of a voice coil motor that positions the head relative to a disc and a microactuator that alters the actuator system without operation of the voice coil motor. A control loop includes a controller responsive to seek commands to operate the voice coil motor, thereby moving the head relative to the disc. An active damping circuit is coupled to the head to operate the microactuator to damp resonance modes of the actuator system.Type: GrantFiled: December 11, 2000Date of Patent: September 14, 2004Assignee: Seagate Technology LLCInventors: JianBo He, Joseph Cheng-Tsu Liu, Kevin Gomez, Tao Zhang

Patent number: 6541931Abstract: A system for positioning a read/write head having a voice coil suitable for coarse control and a piezoelectric transducer (PZT) suitable for fine control. A voice coil control signal and a PZT control signal are generated from a position-indicative signal, both receiving power via a shared supply having a nominal rectified voltage V1. In a preferred method, control signals are both applied to the voice coil and PZT when amplified so that each has a saturation voltage smaller than |V1|.Type: GrantFiled: May 15, 2001Date of Patent: April 1, 2003Assignee: Seagate Technology LLCInventors: Hai Thanh Ho, Margot A. LaPanse, Charles Leon McHenry, Jianbo He
