Abstract: Systems and methods for monitoring an animal include receiving a plurality of biological parameters of the animal from a plurality of biological sensors, receiving location parameters of the animal from at least one location sensor, receiving weather parameters corresponding to ambient weather conditions proximate the animal from at least one ambient weather sensor, and comparing at least one of the parameters generated by the sensors with data representing at least one signature corresponding to the animal to determine if there is an irregular parameter. In response to an irregular reading/parameter being identified, then determining if the identified irregular parameter is related to a health condition of the animal and if the identified irregular parameter is not related to the health condition of the animal, then determining if the identified irregular parameter is related to an illegal activity.

Abstract: The application discloses a compact, multiport converter for interfacing photovoltaic (PV) panels to an energy storage system of a CubeSat. The multiport converter includes a series of connected half-bridge modules, fed by PV panels, that supplies the energy storage system. Further, a control strategy allows the multiport converter to extract a maximum amount of solar power from PV panels under varying irradiation conditions. One example multiport converter includes a multiple-input multiple-output converter that achieves a smaller footprint by utilizing a single inductor for transferring energy. Some aspects also enhance a fault-tolerance capability of CubeSats using a new EPS architecture, for example, by providing independent converters for maximum power point tracking of PV panels. The fault-tolerance capabilities are further enhanced by a new power-down mode for generation and load-side converters. Additionally, certain aspects include an ability to provide a power-reset of the CubeSat from a ground station.

Abstract: This invention relates to methods and systems for determining whether a reference point in a location system has changed used measurement residuals determined from an exchange of messages between reference points. In one embodiment a method of determining whether the location of a first one of a plurality of reference points used in a location system has changed is provided. The reference points each have a known initial position and the method includes the steps of: sending a wireless message between a second reference point and the first reference point and recording the times of sending and receipt of the wireless message; estimating from the recorded times, an estimated distance between the first reference point and the second reference point; comparing the estimated distance to the actual distance between the known initial positions of the first and second reference points to determine a measurement residual; and determining, using the measurement residual, whether the location of the first reference point has changed.

Abstract: Methods and systems are disclosed to determine a permeability value and a permeability image of a rock. The process can include determining labeling of a 3D segment of a rock. The labeled segments can be determined using, for example, computer vision and machine learning and can be used to determine a grain size of a 3D rock segments. The grain size value can be used to determine a permeability value for the 3D rock segment. The permeability value of the 3D rock segment can be used to determine the heterogeneous permeability of the rock.
