Patent number: 10864104Abstract: Method of using a shape-formable apparatus. A shape-formable apparatus can include an envelope defining a chamber, a port positioned to fluidly couple the chamber with ambience, and at least two locking sheets positioned in the chamber in an at least partially overlapping configuration. Each locking sheet can include a major surface, and at least a portion of each locking sheet can be patterned to include solid regions and open regions, the solid regions being movable with respect to one another within the major surface.

Patent number: 10434618Abstract: An apparatus can comprise a body and a first portion. The first portion can be coupled to the body and moveable therewith. The first portion can comprise a rigidifying material and a layer. The rigidifying material can be positioned in a chamber defined by an envelope formed of a gas-impermeable material. A pressure within the chamber can be variable between at least a lower pressure state and a higher pressure state. In the higher pressure state the material is relatively flexible, and in the lower pressure state the material can be relatively less flexible than in the higher pressure state. The layer can be manipulatable by the rigidifying material. More particularly, the layer can have a first state when the pressure within the chamber is in the higher pressure state. In the first state, the layer can be formable by the target surface to take on a desired shape that can be substantially a match of the target surface.Type: GrantFiled: March 17, 2017Date of Patent: October 8, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Thomas R.

Publication number: 20170285457Abstract: A sparse patterned mask for use in a laser ablation process to image a substrate. The mask has a plurality of apertures for transmission of light and non-transmissive areas around the apertures. The apertures individually form a portion of a complete pattern, and a plurality of apertures from one or more masks together form the complete pattern when the masks are imaged. Making a mask sparse provides for a path to remove debris from the substrate during the laser ablation process. Multiple interlaced sparse repeating patterns can create a more complex pattern with repeat distances larger than the individual patterns.Type: ApplicationFiled: June 21, 2017Publication date: October 5, 2017Inventor: Thomas R.

Patent number: 9335015Abstract: The disclosure generally relates to concentrating daylight collectors and in particular to concentrating daylight collectors useful for interior lighting of a building. The concentrating daylight collectors generally include a cassegrain-type concentrator section that provides for a full-tracking solar collector with one moving part and with a high efficiency of coupling of collected solar irradiation to a stationary duct. In some cases, the disclosed concentrating daylight collectors can be used more conventionally, such as for directing sunlight onto a photovoltaic cell for generation of electrical power, or an absorbing surface for extraction of thermal energy.Type: GrantFiled: January 18, 2013Date of Patent: May 10, 2016Assignee: 3M Innovative Properties CompanyInventors: David G.
