Abstract: Provided is a deep dimming control method and a driver control circuit for controlling brightness to a plurality of LEDs, that includes a controller which generates a first pulse width modulation signal, and a second pulse width modulation signal is used to switch between closed loop control and open loop control of the light intensity of the LEDs, and at least one comparator configured to receive the first PWM signal or the second PWM signal from the controller. The comparator compares the first PWM signal to a measured output current signal and regulates the output current to the LEDS in the closed loop control until a predetermined output dimming level is reached. Upon reaching the predetermined output dimming level, the controller generates the second PWM signal to another comparator, and the output current is maintained at a preset value determined by calibration during the closed loop control.

Abstract: An asset inspection system includes a robot and a server. The server receives a request for data from the robot, wherein the requested data comprises an algorithm, locates the requested data in a database stored on the server, encrypts the requested data, and transmits the requested data to the robot. The robot is configured to collect inspection data corresponding to an asset based at least in part on the requested data and transmit the collected inspection data to the server.

Abstract: A lighting control system includes control devices each configured to be coupled with one or more lighting devices. Each of the control devices includes sensor(s) configured to measure a characteristic of an environment, and hardware circuitry configured to connect with a network for one or more of remotely controlling operation of the one or more lighting devices, communicating the characteristic that is sensed, or monitoring information received through the network. The hardware circuitry of the control devices are configured to operate between different operational modes to perform different functions to control the one or more lighting devices based on the characteristic that is measured by the one or more sensors, based on the information received via the network, or based on both the characteristic that is measured and the information received via the network. The system also includes switching hardware configured to change the operational mode of the control devices.

Abstract: According to some embodiments, a system may include an additive manufacturing platform that provides additive manufacturing capability data (e.g., a printer model number, a printer resolution, etc.) to a model customization platform. The model customization platform may receive the additive manufacturing printer capability data and retrieve, from an additive manufacturing model data database, a primary engineering model associated with an industrial asset item. The model customization platform may then create a customized version of the primary engineering model in accordance with the additive manufacturing printer capability data and the primary engineering model. The customized engineering model can then be transmitted to the additive manufacturing platform (e.g., to be printed to create the industrial asset item).
