Title: Microactuator, head gimbal assembly with microactuator, and method of manufacturing head gimbal assembly
Inventor: YAO MING GAO
IPC: G11B21/21
Filed: 2007-07-25
Abstract: <P>PROBLEM TO BE SOLVED: To improve cost-effectiveness by increasing the displacement of a microactuator, while imparting excellent dynamic performance and shock resistance to an HGA (Head Gimbal Assembly).  <P>SOLUTION: The microactuator 20 is configured by including a base part and a metal frame 22 that has two arms facing each other and extending from the base part. At least two thin films PZT are separately loaded on the side surface of each arm so that the displacement of each arm may be increased by the synergetic effect if each arm and the thin film PZT loaded thereon is simultaneously displaced in accordance with driving signals applied to the thin film PZT 21. Moreover, because at least two thin films PZT are loaded on the side surface of each arm, the synergetic effect is generated, thereby achieving an increase in the arm displacement. The at least the two thin films PZT can be arranged on the front side of the same side of the arm, or be separately arranged on the front side of the outer side and/or the inner side.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a system, a method and a computer program product for compensating for crosstalk during the display of stereo content.  <P>SOLUTION: In use, display content is received for being outputted utilizing a display system. Such a display system inherently exhibits crosstalk, whereby an amount of left eye display content is displayed to a right eye of a user and an amount of right eye display content is displayed to a left eye of the user. Thus, before outputting the display content utilizing the display system, the display content is processed utilizing a graphics processor to compensate for the amount of the left eye display content to be displayed to the right eye of the user and the amount of the right eye display content to be displayed to the left eye of the user. In one embodiment where the crosstalk is a function of pixel location, the compensation may also be a function of pixel location.  <P>COPYRIGHT: (C)2008,JPO&INPIT
