Patent number: 8289639Abstract: An optical film structure for backlit displays having two films, both in prisms up configuration. The first film, closer to the light guide, has an array of generally symmetric 90-degree prisms facing the viewer. The second film, farther from the light guide, has an array of generally asymmetric prisms facing the viewer, with one face of the prisms inclined at about 45 degrees and the other face generally perpendicular to the plane of the backlight. The prisms of the first and second films may have an azimuthal angle between them, and may have different pitches from each other. The film structure recycles a portion of the light from the light guide, thereby helping to increase uniformity over the area of the display. The film structure also compresses the light emerging from the light guide, thereby providing a more sharply peaked brightness distribution for the viewer.Type: GrantFiled: November 20, 2008Date of Patent: October 16, 2012Assignee: 3M Innovation Properties CompanyInventor: Leland R. Whitney

Patent number: 8114327Abstract: An indirect bonding apparatus for orthodontic bonding procedures includes a tray having inner wall sections defining a channel for receiving the patient's dental arch. A number of orthodontic appliances are detachably connected to the tray along the channel, and each appliance includes a base for bonding the appliance to the tooth. The wall sections include at least one groove extending along the base of at least one appliance in order to provide a space between the wall sections and the patient's tooth structure when the tray is received on the patient's dental arch. The space hinders the flow of oral fluids such as saliva in directions toward the base in order to help ensure that the fluids do not adversely affect the strength of the resulting adhesive bond between the appliance and the tooth.Type: GrantFiled: September 24, 2009Date of Patent: February 14, 2012Assignee: 3M Innovation Properties CompanyInventors: David K.
