Abstract: Embodiments relate to a RF localization system that determines the position of a RF source of interest (RFSOI) relative to the RFLS. The RFLS includes man-portable nodes that communicate via a self-organizing WAN. Each node includes a communications device conductively coupled to antenna elements oriented in each nodal cardinal direction and battery each communicatively coupled to a control circuit(s). The control circuit is configured to: establish the WAN; capture RSSI values for each antenna element; determine the position of the RFSOI relative to the node; when not functioning as a primary node, transmit the determined position to a primary node or a computing device that's external to the WAN for processing; and when functioning as a primary node, determine the relative position of the RFSOI relative to the plurality of nodes using the received determined position. The primary node determines the position of the RFSOI relative to the nodes.

Abstract: A system for cooling plungers which operate in high pressure pumps. The system uses a plunger having a blind bore formed therein. The blind bore may receive a number of different objects, some of which are fixed to the plunger. A heat exchanger may be installed within the blind bore. The heat exchanger may have internal passages or openings which allow for the circulation of fluid within the blind bore, thus cooling the plunger. The heat exchanger may be formed of a material having a higher thermal conductivity than the material used to form the plunger. This allows the heat exchanger to cool the plunger more effectively than if the plunger were solid or filled with an empty air space. The heat exchanger may be sealed within the bore of the plunger, or exposed.

Abstract: A network intrusion system for a protected network includes a ruleset module configured to receive metadata for rules. The metadata describes, for each of the rules, a set of associated network vulnerabilities. The ruleset module is configured to access vulnerability information describing a set of cumulative vulnerabilities that each is present in at least one network device within the protected network. The network intrusion system includes a rule management module configured to, for each rule of the plurality of rules: identify the set of associated network vulnerabilities described by the metadata for the rule, determine whether there is a match between any of the set of associated network vulnerabilities and the set of cumulative vulnerabilities, and, in response to determining that there is no match, transmit a first command signal to a network security module. The first command signal instructs the network security module to disable the rule.

Abstract: An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.

Abstract: A system in a water body uses buoyant force of gaseous Hydrogen and Oxygen to generate electrical power with one or more turbines that includes power resulting from the buoyant force while transporting the Hydrogen or Oxygen to a higher elevation, without loss of electrons, for conversion to electricity at the higher elevation. Conversion of Hydrogen and Oxygen to water through a Hydrogen Fuel Cell or by burning at the higher elevation may generate additional steam power, hydropower, or purified water. Portable submersible modules may transport the system below or above the water to and from the base of a plumbing portion of the system. The amount of gaseous fuel energy available at the higher elevation is not detrimentally impacted by the generation of electricity by the turbine.

Abstract: A method for measuring a neural response to a stimulus. Measurement circuitry is settled prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.
