Abstract: Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a polymer material comprising at least one thermoplastic polymer, at least one polymer precursor, or any combination thereof, and a plurality of piezoelectric particles dispersed in at least a portion of the polymer material. The piezoelectric particles may interact non-covalently with at least a portion of the polymer material, be covalently bonded to at least a portion of the polymer material, and/or be reactive with at least a portion of the polymer material. The compositions may be extrudable and formable into a self-standing three-dimensional structure upon being extruded. Additive manufacturing processes may comprise forming a printed part by depositing the compositions layer-by-layer.

Abstract: The present disclosure is directed to systems and methods of coordinating threat detection and mitigation among a fleet of trusted devices. As described herein, cybersecurity is a growing concern of many individuals and organizations, especially for those that use multiple electronic devices.

Abstract: Methods and systems for automatically predicting the probability of regulatory compliance approval based on data contained in a data structure. A data structure can be configured to include data collated and collected from one or more regulators (e.g., regulatory agencies) and one or more value chain participants. Such data is inclusive of data indicative of actual approval-request results of applications for regulatory approval by one or more regulators and variable weights assigned to different data elements. A prediction can be then made as to the probability that an application for regulatory approval by a value chain participant will be approved by a regulator based on the data collated and collected and contained in the data structure. This approach predicts the probability that an application for regulatory approval by a value chain participant will be approved and also predicts what is missing for a regulatory approval application.

Abstract: A computer-implemented system and method for entity tracking and identification is provided. A tracker associated with an entity is tracked. Communication is continuously attempted between the tracker and a tracking device associated with an individual in custody of the entity. During one of the attempted communications, an absence of the tracker is determined by identifying a time of the attempted communication and applying a time threshold to the time for the attempted communication. The absence of the tracker is identified when no communication has been established with the tracking device within the time threshold. The entity is classified as missing when the absence of the tracker is determined.
