Patent number: 8384691Abstract: A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area.

Patent number: 8004499Abstract: A capacitive touch sensing system includes a touch surface and sets of substantially parallel electrodes arranged in relation to the touch surface. Each electrode set includes a primary electrode electrically connected to at least two sub-electrodes. The primary electrode is capable of producing greater capacitive coupling to a touch in proximity with the touch surface in relation to capacitive coupling of the at least two sub-electrodes. The sub-electrodes of the electrode sets are arranged in an interleaved pattern configured to increase an effective area of capacitive coupling associated with each electrode set.Type: GrantFiled: November 23, 2010Date of Patent: August 23, 2011Assignee: 3M Innovative Properties CompanyInventors: Bernard O.

Patent number: 7254775Abstract: Touch panel systems and methods are disclosed that can distinguish temporally overlapping touch inputs from single touch inputs so that valid touch position coordinates can be determined. Touch panel systems and methods of the present invention can distinguish overlapping touches by comparing signal magnitudes to specified thresholds, by comparing the rates of change of signal magnitudes or measured positions to determined parameters, by locating the proximity a calculated location to icons or other such active areas, and the like. Because touch panel systems and methods of the present invention can discriminate single touches from double touches, they can be used in multiple user applications such as multiplayer games as well as in applications that may be subject to rapidly successive or overlapping touch inputs.Type: GrantFiled: October 3, 2001Date of Patent: August 7, 2007Assignee: 3M Innovative Properties CompanyInventors: Bernard O. Geaghan, Robert S. Moshrefzadeh, Craig A. Cordeiro, Edward S. Hagermoser, James J. Hart, Paul M. Hatin, Karl P. Hauck, Richard A. Peterson, Jr., Stephen C. Schulz, Gordon F. Taylor
