Patent number: 10753746Abstract: A digitizer system includes a substrate with indicia that uniquely define local areas of the substrate. A multi-mode sensor device, such as a stylus, may sense radiation emitted from the features, and selectively switch to a mode of operation that can sense the indicia and determine therefrom the location of the stylus relative to the substrate.Type: GrantFiled: December 13, 2012Date of Patent: August 25, 2020Assignee: 3M Innovative Properties, Inc.Inventors: Bernard O. Geaghan, Michael W. Dolezal

Patent number: 8459807Abstract: Techniques are described for forming microlens sheeting having composite images that appear to float with respect to the plane of the sheeting. As one example, a method comprises forming one or more images within a sheeting having a surface of microlenses, wherein at least one of the images is a partially complete image, and wherein each of the images is associated with a different one of the microlenses, wherein the microlenses have refractive surfaces that transmit light to positions within the sheeting to produce a plurality of composite images from the images formed within the sheeting so that each of the composite images appears to float with respect to the plane of the sheeting, and wherein forming the one or more images comprises forming the one or more images such that each of the composite images is associated with a different viewing angle range.Type: GrantFiled: June 17, 2008Date of Patent: June 11, 2013Assignee: 3M Innovative Properties CompanyInventors: Sammuel D.

Patent number: 5658656Abstract: A method of using a material as an acoustical barrier in an ambient medium. The material comprises microbubbles having average outer diameters of 5 to 150 microns, bound together at their contact points. The material is characterized by either a porosity of 20 to 60 percent, or by voids between the microbubbles which have characteristic diameter within an order of magnitude of the viscous skin depth of the ambient medium, as calculated at 1 kHz; an air flow resistivity of 0.5.times.10.sup.4 to 4.times.10.sup.7 mks rayls/meter, and an attenuation of sound comparable to mass law performance. The microbubbles can be sintered into direct contact with each other, or one of many types of binder material can be used to support the microbubbles within a composite material.Type: GrantFiled: August 3, 1995Date of Patent: August 19, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Leland R.
