Abstract: A thermal management system includes a receiver configured to store a refrigerant fluid; a refrigeration system having a refrigerant fluid path that includes the receiver, and at least one evaporator disposed in the refrigerant fluid path. The refrigeration system is configured to receive the refrigerant fluid from the receiver through the refrigerant fluid path. The at least one evaporator is configured to receive the refrigerant fluid and to extract heat from at least one heat load having a specified thermal inertia that is in at least one of thermal conductive or convective contact with the at least one evaporator.

Abstract: An exemplary computing system for locating an object in an operational area is disclosed. The computing system having a server and plurality of edge devices. The edge devices having an image sensor configured to capture video data of the operational area from a specified location. The edge devices can process the video data to identify an object and generate a two-dimensional shape representative of the object, generate a vector from a lens of the image sensor through a center point of the two-dimensional shape; and determine relative position of the two-dimensional shape based on geospatial information of the edge device and the vector. The server and one or more of the edge devices receiving video data from a plurality of edge devices and generating a graphic, which defines a position of the object within the operational area based on the vector and location information of each edge device.

Abstract: A thermal management system includes an open circuit refrigeration circuit that has a refrigerant fluid flow path, with the refrigerant fluid flow path including a receiver configured to store a refrigerant fluid, a first control device configured to receive refrigerant from the receiver, a liquid separator, and an evaporator configured to extract heat from a heat load that contacts the evaporator, with the evaporator coupled to the first control device and the liquid separator. The system includes a pump having an inlet and an outlet, with the outlet of the pump coupled to the liquid side outlet of the liquid separator and a second control device that is coupled to an exhaust line, that is coupled to the vapor side outlet of the liquid separator through the second control device. In operation, the evaporator in the open circuit refrigeration circuit would be coupled to a heat load.

Abstract: A system for defending a network against one or more cyber-threats. The system can include a network bus that includes a first node and a second node, such that network traffic flows from the first node to the second node. The system can include an intrusion defense unit connected to the network bus, such that network traffic between the first node and the second node passes through the intrusion defense unit, wherein when a potential cyber-threat is detected in the network traffic, the intrusion defense unit is configured to engage an associated switch to filter the network traffic until the cyber-threat is neutralized.

Abstract: An exemplary system and method for generating a network diagram. The system includes a first interface for receiving one or more first datasets of network data. A processor configured to generate a first network diagram and identify changes in a network by overlaying one or more network diagram layers or a second network diagram on the first network diagram. The one or more network diagram layers corresponding to captured packets of the first datasets or of second datasets and the second network diagram corresponding to captured packets of the second datasets. A second interface for graphically displaying the network diagram by highlighting and/or animating one or more nodes and/or node connections based on at least one of the identified changes from the overlay.

Abstract: A computer-implemented method and system are disclosed for classifying an input data set within a data category using multiple data recognition tools. The method includes identifying at least a first attribute and a second attribute of the data category; classifying the at least first attribute via at least a first data recognition tool and the at least second attribute via at least a second data recognition tool, the classifying including: allocating a confidence factor for each of the at least first and second attributes that indicates a presence of each of the at least first and second attributes in the input data set; and combining outputs of the classifying into a single output confidence score by using a weighted fusion of the allocated confidence factors.
