Abstract: A fluid check-valve for venting gas from a fluidic system comprises a retention body defining a fluid aperture having an upstream side and a downstream side, a hydrophilic porous material held by the retention body and disposed to cover the fluid aperture, and a hydrophobic porous material held by the retention body and disposed to cover the fluid aperture and adjacent the hydrophilic porous material. One face of the hydrophilic porous material is in fluid communication with the upstream side of the aperture, and one face of the hydrophobic porous material is in fluid communication with the downstream side of the aperture. The hydrophilic porous material is configured to retain liquid from the upstream side to hinder passage of gas from the downstream side to the upstream side, and the hydrophobic porous material is configured to hinder passage of liquid from the upstream side to the downstream side.

Abstract: A platform, web application, system, and methods are disclosed for creating digital 3D scenes having digital 3D objects and for creating images of the digital 3D scenes. The platform can be communicatively coupled with the web application. The platform can apply a multi-stage method to convert high-fidelity digital 3D objects into low-fidelity digital 3D objects, store a mapping between them, and transmit low-fidelity digital 3D objects to the web application. The web application can include user interfaces for manipulating low-fidelity digital 3D objects to create low-fidelity digital 3D scenes. The platform can automatically convert low-fidelity digital 3D scenes received from the web application into high-fidelity digital 3D scenes and create high-fidelity 2D images.

Abstract: An intelligent water-monitoring system includes a water-monitoring device installable inline with a building water system (e.g., at an inlet of the system). A plurality of sensors of the water-monitoring device are configured to sense properties of the building water system, such as water pressure and water flow. The water-monitoring device has a valve and a controller configured to automatically shut the valve in response to sensed data indicating a possible problem in the building water system. The intelligent water-monitoring system may include an app executable by a computing device to display information based on the sensed data.

Abstract: A computer-implemented method for alerting a user to the presence of a fault in an electromechanical system in a railway infrastructure, the method comprising: receiving electrical usage data indicative of the value of an electrical usage parameter associated with the electromechanical system; receiving temperature data indicative of the present temperature of the electromechanical system; determining, based on a predetermined relationship between the electrical usage parameter and the temperature, whether or not the value of the electrical usage parameter is indicative of a fault in the electromechanical system and if so, issuing an alert to indicate the presence of the fault.
