Abstract: Diamond bodies and methods of manufacture are disclosed. Diamond bodies are formed from at least a bimodal, alternatively a tri-modal or higher modal, feedstock having at least one fraction of modified diamond particles with a fine particle size (0.5-3.0 ?m) and at least one fraction of diamond particles with coarse particle size (15.0 to 30 ?m). During high pressure-high temperature processing, fine particle sized, modified diamond particles in the first fraction preferentially fracture to smaller sizes while preserving the morphology of coarse particle sized diamond particles in the second fraction. Diamond bodies incorporating the two fractions have a microstructure including second fraction diamond particles dispersed in a continuous matrix of first fraction modified diamond particles and exhibit improved wear characteristics, particularly for wear associated with drilling of geological formations.

Abstract: A comparing module receives first data regarding surroundings of a vehicle from a plurality of sensors in the vehicle, receives second data regarding the surroundings from the plurality of sensors after receiving the first data, compares the first data to the second data, and determines a first difference between the first data and the second data based on the comparison of the first data to the second data. A perception module generates a first set of perception results based on the first data, generates a second set of perception results based on the second data, and determines a second difference between the first data and the second data based on the first set of perception results and the second set of perception results. A diagnostics module determines whether one of the sensors or the perception module is faulty based on a combination of the first difference and the second difference.

Abstract: This document describes techniques and systems that enable radar-based gesture enhancement for voice interfaces. The techniques and systems use a radar field to accurately determine three-dimensional (3D) gestures that can be used instead of, or in combination with, a voice interface to enhance interactions with voice-controllable electronic devices. These techniques allow the user to make 3D gestures from a distance to provide a voice input trigger (e.g., a “listen” gesture), interrupt and correct inaccurate actions by the voice interface, and make natural and precise adjustments to functions controlled by voice commands.

Abstract: Systems and methods of the present disclosure enable a processor to automatically detect duplicate data entries by receiving data entries associated with a user, where each data entry includes a value, a time, an entity identifier, and a location. Pairs of similar data entries are determined by matching the entity identifier and the location pairs data entries. Candidate duplicate data entries are determined based on a proximity in time between data entries of the similar data entries. For each candidate duplicate data entry, a feature vector is generated including the entity identifier, location, value and time, and each feature vector is submitted to a duplicate classification model to automatically determine duplicate data entries from the candidate duplicate data entries, the duplicate classification model being trained according to a historical dispute entries.

Abstract: The disclosed invention provides starting compositions for making lignin hybrid polymers, reactions of lignin and polymer precursors to manufacture lignin hybrid polymers, and final lignin hybrid polymers produced. The most important process requirement is the compatibility of lignin and polymer precursors. Lignin and the polymer precursors must be compatible to assure that the lignin and polymers precursors react and produce a lignin hybrid polymer with useful properties. The lignin hybrid polymers can be in the form of a polyol, a thermoplastic resin, or a thermoset resin. The lignin hybrid polyol, thermoplastic resin, or thermoset resin can be used in a wide range of products including, but not limited to, coatings, adhesives, sealants, elastomers, binders, thermoset resins, thermoplastic resins, and polyurethane systems.

Abstract: Reuse of a thread-local return data structure to prevent a return data structure from being allocated every time asynchronous functions return. The system returns thread operation from the asynchronous function back to the caller function in a manner that the return data structure can be reused for future asynchronous function returns within that same thread. To do so, the system first accesses data that was generated by the asynchronous function in response to the caller function placing the function call to the asynchronous function. To determine if reuse is appropriate, the system determines that the caller function will use the return data structure as populated only once. If so, the system populates the reusable thread-local return data structure and returns that data structure to the caller.

Abstract: A system for reducing a search area for identifying correspondences identifies an overlap region within a first match frame captured by a match camera. The overlap region includes one or more points of the first match frame that are associated with one or more same portions of an environment as one or more corresponding points of a first reference frame captured by a reference camera. The system obtains a second reference frame captured by the reference camera and a second match frame captured by the match camera. The system identifies a reference camera transformation matrix, and/or a match camera transformation matrix. The system defines a search area within the second match frame based on the overlap region and the reference camera transformation matrix and/or the match camera transformation matrix.
