Abstract: Augmented reality (AR) devices, systems and methods are provided to argument captured images of objects of interest. Image data can be obtained for an object of interest by an imaging device of an ear-worn device worn by a user. Augmenting information is generated to augment onto an image of the object. The augmented image is adjusted based on the detection on whether the object is in a field of view (FOV) of the imaging device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a process of manufacturing a product. In one aspect, the method comprises repeatedly performing the following: i) selecting a configuration of input settings for manufacturing a product, based on a causal model that measures causal relationships between input settings and a measure of a quality of the product; ii) determining the measure of the quality of the product manufactured using the configuration of input settings; and iii) adjusting, based on the measure of the quality of the product manufactured using the configuration of input settings, the causal model.

Abstract: A tool for forming a dental restoration includes a mold body configured to provide a customized fit with at least one tooth of a patient. In some examples, the mold body defines an aperture configured to align with a portion of a surface of a tooth. The aperture is sufficiently large to allow placement and flow of restorative material over the desired portion of the surface of the tooth to be restored. The mold body is configured to combine with the at least one tooth of the patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored.

Abstract: The present disclosure provides copolymers prepared by polymerizing a first monomer comprising at least one C?C and/or at least one C?C; and a second monomer of Formula (B): wherein at least one first monomer and/or at least one second monomer comprises a latent-fluoride moiety (e.g., pentafluorophenyl). Upon contacting the copolymers with a nucleophile (e.g., a thiol) and/or a base, the latent-fluoride moiety may release fluoride ions, which may in turn degrade the copolymers by cleaving the O—Si bonds. The copolymers may be useful for drug delivery, or as degradable (e.g., biodegradable) polymers, adhesives, coatings, or structural materials.

Abstract: A tool for forming a dental restoration includes a mold body configured to combine with a tooth of a patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth. In some examples, the portion of desired tooth structure defines an interproximal surface of the tooth. The mold body may include, in some examples, a base member configured to provide a customized fit with at least one tooth of the patient to attach the mold body to the at least one tooth, and an interproximal member extending from the base member and configured to be disposed between adjacent teeth of the patient when the base member is fit over the at least one tooth. The interproximal member defines a surface of the mold cavity.

Abstract: A microbial detection device and methods of use are provided. The device comprises a water-proof pouch that includes a first wall portion, a second wall portion, and a porous membrane filter disposed in the pouch between the first and second wall portions. The filter membrane divides the pouch into first and second compartments. A dry, cold water-soluble gelling agent is adhered to the pouch in the first compartment and an absorbent pad is disposed in the second compartment. A release liner removably adhered to the first adhesive layer.

Abstract: The present disclosure provides compositions comprising: a) a copolymer prepared by a method comprising polymerizing in the presence of a metathesis catalyst: i) a first monomer, wherein each instance of the first monomer is independently of the formula: or salt thereof; ii) a second monomer, wherein each instance of the second monomer is independently of the formula: or a salt thereof; iii) optionally a third monomer, wherein the third monomer is different from the first monomer and the second monomer; and iv) optionally a reprocessing catalyst; and b) optionally the reprocessing catalyst; wherein the reprocessing catalyst is a Brønsted acid, Lewis acid, Brønsted base, Lewis base, or a salt thereof; provided that the composition comprises at least one of the reprocessing catalyst of iv) and the reprocessing catalyst of b). The compositions may be reprocessed (e.g., remolded) under elevated temperature and/or elevated pressure.
