Abstract: Techniques are described herein for selecting, curating, normalizing, enriching, and synthesizing the results of user experience (UX) tests. In some embodiments, a system receives input defining or modifying a theme schema for classifying results of user experience tests. Responsive to receiving the input, the system trains a themer model based at least in part on example classifications in a training dataset, where the classifications map results to themes within the theme schema. When a new set of results for a user experience test is received, the trained machine learning model may generate a set of predicted themes to classify the test results. The output of the model may be used to render user interfaces and/or trigger other actions directed to optimizing a product's design.

Abstract: Techniques are described herein for selecting, curating, normalizing, enriching, and synthesizing the results of user experience (UX) tests. In some embodiments, a system identifies a set of expectation elements associated with one or more UX tests. An expectation element may specify, using unstructured data that does not conform to a schema, an expectation for a user experience and a respective outcome for the user experience. A themer model may generate predictions that map the respective expectation elements to a theme from a theme schema, which may include a plurality of themes. A selector model may generate selection scores for the expectation elements. The predicted themes and selection scores may be used to render user interfaces and/or trigger other actions directed to optimizing a product's design.

Abstract: A vehicle monitoring device includes a camera or other optical sensor configured to be disposed at a trailing end of a first vehicle system. The camera or other optical sensor is configured to output one or more images or video of a field of view behind the first vehicle system. The monitoring device also includes a controller configured to receive output from one or more sensors and to activate the camera or other optical sensor to output the one or more images or video based on the output from the one or more sensors. The output from the one or more sensors indicates one or more of a change in movement of the first vehicle system, a temperature, an acoustic sound, or movement of a second vehicle system.

Abstract: In examples provided herein, upon receiving notification of a computational task requested by a package to provide an experience to a user, a remote node management engine identifies computing nodes for performing the computational task and determining available processing resources for each computing node, where a computing node resides at networked wearable devices associated with the user. The remote node management engine further selects one of the computing nodes as a primary controller to distribute portions of the computational task to one or more of the other computing nodes and receive results from performance of the portions of the computational task by the other computing nodes, and provides to the selected computing node information about available processing resources at each computing node.

Abstract: A method of making colloidal crystals using seed programmable atom equivalents (PAEs) and growth programmable atom equivalents (PAEs) for at least two stage growth. The seed and growth PAEs each include nanoparticles functionalized with oligonucleotides with sticky ends. Seed PAEs have sticky ends adapted to hybridize to each other to form a first duplex, and growth PAEs have sticky ends adapted to hybridize to a respective ones of the seed PAEs and to each other to form second, third, and fourth duplexes. Using base mismatches in the sticky ends of the growth PAEs and a two stage cooling, the first duplex having a higher melting temperature than the other duplexes nucleate the seed PAEs as seeds in a first stage and remaining duplexes form in a second lower temperature stage for growth on the seeds.

Abstract: Fiber optic amplification in a spectrum of infrared electromagnetic radiation is achieved by creating a chalcogenide photonic crystal fiber (PCF) structure having a radially varying pitch. A chalcogenide PCF system can be tuned during fabrication of the chalcogenide PCF structure, by controlling, the size of the core, the size of the cladding, and the hole size to pitch ratio of the chalcogenide PCF structure and tuned during exercising of the chalcogenide PCF system with pump laser and signal waves, by changing the wavelength of either the pump laser wave or the signal wave, maximization of nonlinear conversion of the chalcogenide PCF, efficient parametric conversion with low peak power pulses of continuous wave laser sources, and minimization of power penalties and minimization of the need for amplification and regeneration of pulse transmissions over the length of the fiber, based on a dispersion factor.

Abstract: A monitoring system for monitoring drain pipe and/or plumbing fixture clogging in a plumbing system is disclosed. The monitoring system includes a monitoring unit that attaches to a drain pipe using a noninvasive attaching system, such as a hook and loop material. The monitoring system provides a warning and/or controls a shut-off valve when a blockage is detected in the drain pipe or the plumbing fixture. A handheld sensor device is also disclosed for inspecting a plumbing system. The handheld device has a handheld case, a detection circuit within the case, an acoustic or capacitive sensor, a display, and an audible alarm. The sensor communicates with the detection circuit and is connected to the case by a flexible connector so that the sensor can be easily positioned and held on the exterior surface of a drain pipe. The handheld device provides a visual and/or audible indication of the presence of liquid within the drain pipe.

Abstract: An asset management system includes a database with a plurality of tables each containing a plurality of fields of information, selected of the fields in one table corresponding to fields in at least one of the other tables with lines of communication so that activation of a selected field in one of the tables will enable activation of a corresponding field in one of the other tables, and each table may contain one or more fields which are linked together with corresponding fields in other tables and permit linking back and forth between fields.

Abstract: The invention is a method of joining two belt ends together, either laterally or longitudinally, and the resulting belt. The two ends can be of two different belts being joined, a short section added to replace a damaged section of a belt, or two ends of the same belt. Moreover, the belt or belts can be damaged or intentionally cut in preparation of their joining. The belt ends are stripped of their rubber or elastomeric coating that covers the cord core, and the ends can be fashioned in any shape such that one belt end complements the other end when abutted. The ends are joined and a new rubber layer is then bonded to the belt above and below the cord core.

Abstract: The invention is a method of splicing two damaged ends of a conveyor belt together such that the resultant spliced belt is stronger than typical splice methods. The damaged belt is cut apart and the ends are prepared so that the ends may be spliced together. The belt ends are stripped of the rubber coating that covers the cord core through cutting or abrading the coating away. The belt ends can be prepared in any fashion from blunt end cuts to stepping the cut of the core such that the steps of one end of the belt complement the steps of the other end of the belt. The prepared belt ends are mated together and sewn. A new layer of rubber is then placed over the sewn portion of the belt. The new layer of rubber is then vulcanized, through either hot or cold vulcanization techniques. The resultant sewn and vulcanized belt is a stronger belt than a belt repaired by only mechanical or vulcanization methods.

Abstract: The present invention describes a tensioner that automatically increases the effective torque on the support arm over time. The tensioner is comprised of a torsion cam engaging the support arm of the scraper blade assembly, a torsion cable engaging the cam, a tension rod with a spring surrounding the rod secured to the torsion cable. Over time, as the scraper blade wears down and the spring force decreases, the torsion cam is slowly rotated to increase the torque arm of the invention and thereby increase the effective torque on the support arm and compensate for the decrease in spring force. This invention may be adapted for use with any existing scraper blade assembly.
