Publication number: 20090178704Abstract: A solar electric module having a layered construction including a light redirection layer and light transmitting materials that encapsulate the solar cells of the module. The solar electric module provides for weight mitigation and/or moisture control features. The weight mitigation feature provides for the use of weight mitigation layers to reduce the volume of glass in a transparent top cover, while providing an increased distance between the light redirection layer and the transparent top cover. The increased distance supports increased spacing between solar cells. The moisture control feature provides perforations in a metallic coating layer and/or light redirection layer to support migration of moisture into and out of the encapsulating layers. The light redirection layer can be an asymmetric redirection layer (for example, light scattering layer) or a symmetric redirection layer (for example, a diffractive optical element).Type: ApplicationFiled: February 4, 2008Publication date: July 16, 2009Inventors: Juris P. Kalejs, Michael J. Kardauskas, Bernhard P. Piwczyk

Patent number: 7154481Abstract: A touch sensing method and a touch sensing device are described for sensing a location of a touch. When the touch sensing device is touched, a first conductive layer disposed on a supporting layer is deflected toward a second conductive layer. The touch location is determined by sensing the change in capacitance at the location of the touch. A change in capacitance at the touch location is sensed by driving one of the conductive layers with an electrical signal referenced to the other conductive layer and measuring the current flow between the conductive layers. The sensed change in capacitance is greater than a change in the external capacitance of the touch sensor.Type: GrantFiled: June 25, 2002Date of Patent: December 26, 2006Assignee: 3M Innovative Properties CompanyInventors: Elisa M. Cross, Robert S. Moshrefzadeh, Anthony F. Chernefsky, Frank J. Bottari, Craig A. Cordeiro, Stephen C. Schulz, Michael J. Kardauskas

Publication number: 20040123895Abstract: A diffractive structure for responding to incident radiation includes a substrate having a diffractive surface and a coating layer disposed over the diffractive surface, the coating layer having an index of refraction substantially different from that of the substrate. The diffractive surface comprises a three-dimensional pattern selected to diffract incident radiation with substantial efficiency into one or more diffraction orders other than the first order and to redirect the diffracted radiation from the structure in at least two directions at angles that are greater than a critical angle required for total internal reflection. In application of the diffractive structure to solar cell modules, a diffractive structure disposed in spaces between plural solar cells redirects incident radiation from the area within the spaces onto the solar cells, thus concentrating solar radiation onto the cells.Type: ApplicationFiled: October 22, 2003Publication date: July 1, 2004Applicant: SunRay Technologies, Inc.Inventors: Michael J. Kardauskas, Bernhard P. Piwczyk
