Publication number: 20120066624Abstract: A method and apparatus provides for controlling movement of one or more graphical user interface (GUI) objects such as a cursor and/or a window. In one example, the method and apparatus applies a warp operation to the GUI object that uses display content information to determine where to move the cursor and/or window. The destination position of the GUI object is determined based on content identification information associated with display content such as name, serial number or label that identifies the display content. The display content may be any visible object to be displayed on the display screen, including but is not limited to, windows, taskbars, sidebars, docks, program launchers, icons, controls, and background (wallpaper). The warp operation may be an immediate relocation of the GUI object to the destination position without any user intervention during the relocation.Type: ApplicationFiled: September 13, 2010Publication date: March 15, 2012Applicant: ATI TECHNOLOGIES ULCInventors: Lawrence S.

Publication number: 20120066640Abstract: Apparatus provides for providing multi-mode warping of graphical user interface (GUI) objects, such as but not limited to a pointing object (e.g., cursor) and a window. In one example, the apparatus includes logic operative to provide a user interface that allows a user to select different warping modes. In one example, a user may select a pointing object warping mode and/or a window warping mode. In the pointing object warping mode, the apparatus applies a warp operation to one or more pointing objects that uses display content information to determine where to move the pointing object. In the window warping mode, the apparatus applies a warp operation to one or more windows that also uses display content information to determine where to move the window. The destination position of the GUI object is determined based on content identification information associated with display content such as name, serial number or label that identifies the display content.Type: ApplicationFiled: September 13, 2010Publication date: March 15, 2012Applicant: ATI TECHNOLOGIES ULCInventors: Lawrence S.

Patent number: 7528790Abstract: Techniques are provided to prevent undesired and/or unauthorized analysis and access to electronic components designs. A shield can be utilized to prevent invasive and/or non-invasive analysis methods such as the use of x-rays to determine the structural configuration and/or component makeup of an embedded antenna. In addition, a damageable material that can be utilized alone or in conjunction with the shield is also provided. When attempting to access the antenna and/or components included therein, any inappropriate force or exposure to certain elements, such as heat, will cause the material and the antenna and/or the components therein to be damaged or melted beyond a point of useful recognition for the entity. Furthermore, thin films can be utilized to construct one or more portions of the antenna to the same effect. In addition, the antenna and/or components can be configured for actively reconfiguring a resonant frequency of the antenna.Type: GrantFiled: June 12, 2007Date of Patent: May 5, 2009Assignee: Ethertronics, Inc.Inventors: Laurent Desclos, Seung-Woong Choi, Jun-Ho Park, Sung-Ki Jung, B.
