Abstract: Systems and methods for using machine learning models to predict an outcome of a product test are described. According to certain aspects, an electronic device may generate a machine learning model using training data indicating a set of results of a set of products tested according to a specific product test. The electronic device may access a set of inputs comprising a set of additional results of at least one additional product tested according to a modified product test, and input the set of inputs into the machine learning model. Based on an output of the machine learning model, the electronic device may predict whether the at least one additional product would pass or comply with the original specific product test.

Abstract: Systems and methods for using machine learning to assess eligibility for product certification are disclosed. According to certain aspects, a server computer may train a set of machine learning models using a set of training data, where the set of machine learning models may be specific to products and certifications for the products. The server computer may access product specifications associated with a set of products sought to be certified, and may analyze the product specifications using the an appropriate machine learning model(s), the output of which may indicate whether the set of products is eligible for certification, the set of products is ineligible for certification, or the product specifications need further review.

Abstract: A test apparatus for testing of a stop mechanism on a saw includes a support arm movable relative to a blade of the saw from a first position to a second position. The test apparatus also includes a simulation member coupled to the support arm. In the first position, the first end of the simulation member is offset from a portion of the blade of the saw, and in the second position, the first end of the simulation member is adapted to be in contact with the portion of the blade of the saw. The test apparatus further includes circuitry operatively connected to the simulation member to replicate an electrical property of a human finger such that contact between the blade and the first end of the simulation member triggers the stop mechanism of the saw.

Abstract: An apparatus for applying a primary coating and a secondary coating to an optical fiber is disclosed. The apparatus includes at least one pressurized source of primary coating, a first primary reservoir for applying a first layer of the primary coating to the optical fiber, a first primary die including a first primary land configured to size the first layer of the primary coating, a second primary reservoir for applying a second layer of the primary coating to the optical fiber, a second primary die including a second primary land, a pressurized source of the secondary coating, a secondary reservoir for applying a layer of the secondary coating to the optical fiber, and a secondary die including a secondary land configured to size the layer of the secondary coating.

Abstract: An improved optical fiber cable is fabricated from a core surrounded by a protective sheath having a radially-varying elastic modulus. The core comprises one or more longitudinally extending optical fibers. The protective sheath comprises least a first coating layer portion and a second coating layer portion. The first and second coating layer portions are comprised of a common coating material. A modifier is added to the coating material comprising the first coating layer portion. Likewise, a modifier is added to the coating material comprising the second coating layer portion. The addition of a modifier to the first coating layer portion and the addition of a modifier to the second coating layer portion cause the coating to have an elastic modulus that varies in a radial direction along radii extending outwardly from a center of the core of the cable. The core may be, for example, a single optical fiber, a bundle of optical fibers, an optical fiber ribbon, a stack of optical fiber ribbons, etc.
