Abstract: Curable compositions include a non-aromatic epoxy-functional epoxy resin adduct, a non-aromatic epoxy resin, and a non-aromatic anhydride-based curing agent. The epoxy resin adduct is the reaction product of a reaction mixture including a polyfunctional thiol and a poly functional epoxy resin. The cured composition has an Izod Impact Test (Notched Izod) test method (ASTM D256) value of at least 40 J/m and is color stable such that upon exposure to an acid bath in accordance with the Acid Bath Test Method, exhibits a ΔE 94 color change of less than 1.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining causal models for controlling environments. One of the methods includes obtaining data specifying baseline probability distributions for each of a plurality of controllable elements; maintaining a causal model; repeatedly performing the following: selecting control settings for the environment based on the causal model and values for a particular internal parameter of the control system that are sampled from a range of possible values; selecting control settings for the environment based on the baseline probability distributions; monitoring environment responses to the control settings selected based on the causal model and the control settings selected based on the baseline probability distributions; determining, for each of the possible values, a measure of a difference between a current system performance and a baseline system performance; and updating how frequently each of the possible values is sampled.

Abstract: A heads-up display includes a windshield with a standardized wedge profile and an embedded reflective polarizer and a display. The reflective polarizer is disposed between, and spaced apart from, opposing outermost first and second major glass surfaces of the windshield. The heads-up display forms a virtual image for viewing by the eye of a passenger. An image emitted by the display may include a first image ray emitted from a predetermined region of the display and incident on the outermost first major glass surface of the windshield at an angle of incidence greater than about 60 degrees, with at least 90% of the incident first emitted image ray polarized in a plane of incidence of the first emitted image ray.

Abstract: A system including a polymeric sheet. The polymeric sheet comprises a base sheet having a first surface and a second surface opposite the first surface and a multiplicity of spaced rails projecting from the first surface of the base sheet. The rails comprise a stem portion attached to and substantially upright from the first surface of the base sheet and a top portion on the distal end of the stem opposite the base sheet. The top portion comprises a first surface opposite the base sheet and a second surface facing the first surface of the base sheet. Additionally, the rails have a length greater than the width of the stems. The first surface of the base sheet, the second surface of the top portion and the surface of the stem defines a cavity with walls, and an adhesive coated on at least a portion of the cavity wall.

Abstract: A method and associated system provides automated abrasive paint repair using automated abrasive paint repair devices that selectively sand, buff, and polish a substrate in response to received instructions generated by a controller. The controller receives coordinates of each identified defect in the substrate along with parameters describing characteristics of each defect, selects a sanding process, a buffing process, and/or a polishing process based on empirically derived rules established by skilled/expert human operators and the received parameters. The controller outputs instructions to cause the automated abrasive paint repair devices to execute the selected sanding process, buffing process, and/or polishing process using the received parameters. The empirically derived rules and parameters may be stored in a lookup table and/or updated by a machine learning module.

Abstract: A cooling film for use in passively cooling an antenna includes an antisoiling layer secured to a first major surface of a reflective microporous layer. The reflective microporous layer comprises a first fluoropolymer and is diffusely reflective of electromagnetic radiation over a majority of wavelengths in the range of 400 to 2500 nanometers. The film can also include an infrared-absorptive layer secured to a second major surface of the film opposite the first major surface, and the infrared-absorptive layer is optionally metallized. The film is shaped into a self-supporting three-dimensional structure, such as fins, and a thermally conductive material is inside the structure and secured to a portion of the antenna, either the front side of the antenna for the non-metallized film or the back side of the antenna for the metallized film.

Abstract: Augmented reality-based training systems that can dynamically construct and render AR content based on physical attributes of a user to train the user to correctly fit one or more articles of a personal protective equipment (PPE) onto the user's body. In some examples, an AR system includes a display and a computing device having a memory and one or more processors. The memory can include instructions that, when executed by the processors, simulate a fitting of PPE to a worker. The system can capture an image of a worker, select a digital model of the PPE, determine alignment of the PPE to the worker, and output for display augmented reality content that includes a composite image of the worker overlaid with the digital model of the PPE in accordance with the determined alignment.
