Abstract: An industrial extract, transform, and load (ETL) system extracts and transfers data from proprietary industrial systems and devices to cloud-level systems or other higher level applications. The industrial ETL system uses application connectors that are designed to interface with various types commonly used or proprietary industrial systems and devices—including but not limited to industrial controllers, open platform communications (OPC) servers, databases, MQ telemetry transport (MQTT) brokers, motor drives, telemetry devices, etc.—and to extract data from those systems in a manner that reduces the impact on those systems' core functionalities relative to conventional ETL approaches. The system's application connectors use the same technology stack to communicate with multiple different devices and systems that are commonly found in industrial software architectures.

Abstract: A method of operating a vehicle includes receiving brake sensor data indicative of measured actuator outputs of a decentralized brake system's brake actuators. For each brake actuator, a vehicle controller calculates: a normalized corner output using the measured actuator output and a commanded target output for that brake actuator, and a weighted average using the normalized corner output of that brake actuator and a vehicle-calibrated weight value determined from the vehicle's current speed and steering angle. The controller calculates an actuator error percentage as an absolute value of a mathematical difference between the weighted averages of the brake actuators, and detects an actuator fault when the actuator error percentage exceeds a vehicle-calibrated fault deviation threshold determined from the vehicle's current speed and steering angle.

In one embodiment, the system includes a membrane electrode assembly (MEA) that includes a polymer electrolyte membrane (PEM), an anode, and a cathode. First and second gas diffusion media are positioned adjacent the cathode and anode, respectively.

In use, hydrogen is electrochemically pumped across the MEA and collected in the hydrogen gas collector. The PEM is kept properly humidified by the humidifying membrane, which releases water into the second gas diffusion medium.

Abstract: An active cooling assembly is described. One embodiment of the active cooling assembly includes a fin configured to enable convective heat transfer to an airflow passing over the fin. A boundary layer accumulates between the fin and the airflow, and the boundary layer includes a region of heated air attached to a side of the fin.

The fin is coupled to a stationary arm, and the blade is coupled to a swing arm. The swing arm and a spring are driven at a resonant frequency by an actuator.

Abstract: A phase change material (PCM) is used as thermal storage for lighting systems. The PCM is placed in a thermally conductive container in close contact with the lighting system. As the PCM absorbs heat, it changes from a solid to a liquid state, but the temperature of the PCM is clamped at its melting point temperature. For LED-based systems, the PCM is selected to have a melting point such that the junction temperatures of the LEDs in the system are maintained at approximately their optimum operating temperature inside the lighting system housing. Because the thermal conductivity of the molten PCM is poor, a low thermal resistance heat flow path is provided from the PCM to the container.
