Patent number: 10347278Abstract: A data storage device is disclosed comprising a first actuator configured to actuate a first head over a first disk comprising a first plurality of tracks defined by first servo sectors, and a second actuator configured to actuate a second head over a second disk comprising a second plurality of tracks defined by second servo sectors. The first actuator is controlled based on the first servo sectors in order to first write data to the first disk, and the second actuator is controlled based on the second servo sectors in order to second write data to the second disk. The first writing is inhibited when a shock signal generated based on a shock sensor exceeds a first shock threshold, and the second writing is inhibited when the shock signal exceeds a second shock threshold different from the first shock threshold.Type: GrantFiled: October 24, 2018Date of Patent: July 9, 2019Assignee: Western Digital Technologies, Inc.Inventors: Toshihisa Kiyonaga, Peng Huang, Junya Takeda, Edward C.

Patent number: 9583030Abstract: A display drive circuit of the invention has: an initial-color-gamut-apex-coordinate-storing unit capable of storing initial color gamut apex coordinates; a user-target-color-gamut-apex-coordinate-storing unit capable of storing user target color gamut apex coordinates; a saturation-expansion-coefficient-deciding unit for deciding expansion coefficients of saturation data based on the initial and user target color gamut apex coordinates; and an expansion unit for expanding saturations of display data based on the saturation expansion coefficients. The expansion coefficients of saturation data are decided based on the initial and user target color gamut apex coordinates, and saturations of display data are expanded according to the expansion coefficients. Thus, the degree of expanding the saturations can be controlled for each color gamut or each of R, G and B color properties of an LC display panel.Type: GrantFiled: December 23, 2013Date of Patent: February 28, 2017Assignee: SYNAPTICS JAPAN GKInventors: Yoshiki Kurokawa, Yasuyuki Kudo, Hiroyuki Nitta, Kazuki Homma, Junya Takeda
