    Abstract: Described herein are magnetic sensors (e.g., force sensors) as well as methods of making and using thereof The magnetic sensors can employ a soft magnetic composite (e.g a composite comprising a population of magnetic particles dispersed within an elastomeric resin) paired with a magnetometer. These sensors can overcome many of the traditional shortcomings that have hampered the effectiveness of existing compression sensors in certain applications, including large size, a lack of 3-dimensional sensing capacity, need for sensors to incorporate rigid components, and/or signal quality issues associated with the orientation or deformation of soft composites under compression.

    Abstract: The present disclosure provides systems and methods for extracting information from image data captured using an unmanned aircraft system (UAS). The disclosed systems and methods may capture image data using an imaging device mounted to the UAS, which may include a plurality of images of an environment. Each image may be associated with a particular area of the environment and a timestamp. The imagery may be used to construct one or more multi-temporal orthomosaics. The disclosed systems and methods may generate information representative of a dynamic evolution of an event impacting the environment over time based on the multi-temporal orthomosaic(s). The systems and methods may also calculate a rate of spread (ROS) of the event based on the information representative dynamic evolution of an event impacting the environment over time. In an additional aspect, techniques for synchronizing image data captured by the UAS to calibrated image data are disclosed.

    Abstract: The invention is directed to stable and labile crosslinked water swellable polymeric microparticles that can be further gelled by covalent crosslinking in a transamidation reaction, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker comprising PEI or other polyamine based tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker and swelling of the particle, so as to form a stable gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric microparticles are injected into a well and when the heat and/or pH of the well cause degradation of the labile crosslinker and when the microparticle expands, the tertiary crosslinker crosslinks the polymer to form a stable gel, thus diverting water to lower permeability regions and improving oil recovery.
