Abstract: This disclosure describes electrically powered fluid (liquid) pumps having an electric motor or actuator attached to a power source with a power sensor configured to measure the power draw of the motor while the pump is operating.

Abstract: Disclosed herein is an inflatable watercraft barrier in one example having an inflatable perimeter tube. Also disclosed is a diaphragm sealed to the perimeter tube to form the watercraft barrier between a watercraft and the water in which the watercraft barrier and watercraft float. In one example, a portion of the perimeter tube forms a gate portion which is at least partially selectively deflated so as to be denser than water, and therefore rotates about a gate pivot such that the watercraft may enter the watercraft barrier through the gate portion. Also disclosed is a water pump in fluid communication with the watercraft barrier so as to evacuate water from between the watercraft barrier and the watercraft.

Abstract: An arrangement and process of mitigating contaminants has a flow element intermediate a first space with contaminated matter (including contaminated gas) and a second space. Contaminated matter is drawn from the first space into the flow element and then urged into segregated contaminated gas and residual contaminated matter collected in the second space. Segregated contaminated gas is merged with gas from the second space to form mixed gas and treated to form primary treated gas which is directed to generate at least some of the drawing of contaminated matter from the first space into the flow element. Mixed gas can be treated by passing it through passages in the flow element coated with decontaminating agent and/or through a decontamination unit. The flow element allows for air flow to effectively act as a one-way barrier obstructing migration of contaminated matter from the second space back to the first space.

Abstract: Systems and methods for model based vehicle navigation are provided. In one embodiment, a navigation system: a strapdown navigation processor; a propagator-estimator filter, the navigation processor configured to input inertial sensor data and navigation corrections from the filter to generate a navigation solution comprising a vehicle velocity estimate and a vehicle attitude estimate; a vehicle physics model configured to perform calculations utilizing dynamics equations for a rigid body. The model inputs 1) vehicle state estimates from the navigation solution and 2) platform inputs indicative of forces acting on a vehicle platform. The model outputs a set of three orthogonal predicted translational acceleration measurements based on the inputs.

Abstract: An apparatus for treating contaminated fluid has a UV lamp within an elongate housing, typically rectangular shaped. Deflector baffles within the housing create a meandering pathway perpendicular to the lamp for exposing the fluid to the UV light along the entire length of the pathway. Fins create multiple channels in the pathway to substantially increase internal surface area contact with the fluid. A photocatalytic coating on the baffles, fins and internal surfaces of the housing is maintained within a pre-set radial distance, preferably within about 75 mm, from the lamp for optimal creation of a photocatalytic reactant. The fluid flowing along the pathway, including channels, is also maintained in close proximity to the lamp and has adequate time for exposure to the ultraviolet light and photocatalytic reactant for treatment before exiting the housing.

Abstract: Systems and methods for indexing and searching for digital media in a multi-player gaming network are disclosed. In a game module stored locally in each client device, a content editor application generates a user interface through which a player may create, or search for, a personal visual symbol. Search queries are processed to determine asset signatures and, based on the asset signatures, corresponding stored personal visual symbol data are identified.

Abstract: A fluid monitoring assembly includes a conduit having a wall defining a lumen for carrying fluid. A sensor mount is integrally formed with the wall of the conduit and extends generally transverse with respect to a longitudinal axis of the conduit, the sensor mount including an aperture defining an inner surface extending to the lumen. The assembly includes a sensor configured to be removably secured within the sensor mount, the sensor having an elongate body terminating at one end thereof in a sensing portion, the elongate body having a male projection on a portion thereof and configured to rest within the inner surface of the sensor mount. The assembly further includes a housing having first and second portions connected to one another, the housing defining an interior portion configured to encapsulate the conduit, at least a portion of the elongate body of the sensor, and the sensor mount.
