Patent number: 9052745Abstract: A multi-monitor computer system includes a plurality of display devices communicating with at least one computing device executing an application management procedure. The application management procedure enables an application window available on one display device to be moved entirely to another display device by selecting the other display device from a dialog box displayed in response to a pointer-dragging input gesture on the application window.Type: GrantFiled: September 3, 2009Date of Patent: June 9, 2015Assignee: SMART Technologies ULCInventors: Douglas B. Hill, Michael Rounding, Daniel Mitchell, David Martin, Luqing Wang, Gregory Forrest

Patent number: 8576172Abstract: A touch system comprises overlapping coordinate input sub-regions defining a generally contiguous input surface. Each coordinate input sub-region generates pointer coordinate data in response to pointer contacts thereon. When a pointer contact is made on a region of a coordinate input sub-region that overlaps with an adjacent coordinate input sub-region, each overlapping coordinate input sub-region processes acquired images to derive pointer data and triangulates the position of the pointer using the derived pointer data. Thereafter, the triangulated positions generated by the overlapping coordinate input sub-regions are processed in accordance with defined logic thereby to determine the position of the pointer contact relative to the touch surface.Type: GrantFiled: November 30, 2011Date of Patent: November 5, 2013Assignee: SMART Technologies ULCInventors: Douglas B. Hill, Scott Yu Tseng Su, David E. Holmgren

Patent number: 8325134Abstract: A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.Type: GrantFiled: January 31, 2011Date of Patent: December 4, 2012Assignee: SMART Technologies ULCInventors: Douglas B. Hill, Gerald D. Morrison

Patent number: 6025657Abstract: A power operator for switchgear and the like is provided that is capable of either power or manual operation without the necessity of any decoupling or mode selection. The power operator is compact and easily affixed over a manual operating shaft of switchgear. The manual drive capabilities are always coupled for operation without any backdriving of the power source. The power operator includes a drive output affixed to the switchgear operating shaft, a manual operating shaft, and an arrangement for selectively coupling a power-driven input to the switchgear operating shaft. In a specific arrangement, the control arrangement of the power operator senses the position of the drive output and also senses the current drawn by the drive source. When controlling switchgear having a stored energy mechanism, operating positions are detected by sensing the tripping of the stored energy mechanism via the sensed current through the drive source.Type: GrantFiled: June 12, 1998Date of Patent: February 15, 2000Assignees: S&C Electric Company, S&C Electric Canada Ltd.Inventors: Steve Chung-Bun Lo, Todd W. Klippel, Douglas B. Hill, Terrence S. Kerr
