A system includes a nuclear reactor having a plurality of fuel rods of radioactive decay material distributed within and embedded within a heat exchange matrix. A plurality of coolant tubes is distributed within and embedded within the heat exchange matrix, interspersed with the plurality of fuel rods. The heat exchange matrix is configured to conduct heat from the fuel rods to the coolant tubes.

Nuclear-based heat and power for low-earth orbit (LEO) and deep space missions

A system and method for performing time-dependent reliability prediction of a printed circuit board (PCB) embedded in a sensor that monitors the health (viz., performance) of operating equipment subject to different environmental stressors. The method includes developing a digital twin (DT) of the physical PCB, generating sensor data, transmitting the sensor data, and receiving sensor data and historical conditional data by the twinning module, wherein the historical condition data includes known failure data of one or more electronic components of the circuit board based on an internal condition or and external condition. The method further includes embedded physics-based reliability models informed by inputs from the sensor data and the historical conditional data, generating a real-time failure prediction signal based on the physics-based reliability models, and reporting the real-time failure prediction signal. The circuit board may include printed circuit boards (PCBs), particularly additively-manufactured printed circuit boards (AM-PCBs).

Digital twins (DT) for circuit board reliability prediction

A sensor system for a passenger conveyance system includes a multiple of 3D sensors mounted to a movable structure within a vertical shaft and/or a horizontal shaft and a processing module in communication with the multiple of 3D sensors, the processing module operable to identify an obstruction within the horizontal or vertical shaft.

Detection and control system for elevator operations

A two-phase liquid/inert gas flow inerting fire suppression system is provided having improved liquid fire suppressant distribution within the inert gas flow. The system includes a flow distribution network having a first pipe interconnected with a second pipe at a flow splitting tee. A liquid flow redistribution device is disposed in the first pipe upstream with respect to fluid flow of the flow splitting tee.
