In an example, an expected sky condition is calculated for a geographic location, a time of day, and a date based on a mathematical model. A predicted distribution of direct and interreflected solar radiation within the environment is calculated based on the expected sky condition. Measurement data from one or more photosensors is obtained that provides measurements of an initial distribution of direct and interreflected radiation within the environment, including radiation from solar and electrical lighting sources. A target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting is determined, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, to achieve the target distribution of direct and interreflected radiation within the environment. Output parameters are set to one or more devices to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment, including diffusion characteristics of the materials between environments.

Exemplary embodiments are provided of wireless emergency stop systems. In an exemplary embodiment, a wireless emergency stop system includes a machine safety device wired to a machine stop circuit for stopping operation of a machine when the machine stop circuit is activated. The machine safety device includes a wireless communication interface. The system also includes multiple personal safety devices. Each personal safety device includes a wireless communication interface for wireless communication with the machine safety device, and an emergency stop switch. The emergency stop switch is configured to, when activated, transmit an emergency stop signal to the machine safety device to trigger an emergency stop of the machine. The machine safety device is configured to maintain wireless connections with more than one of the multiple personal safety devices at the same time. Example methods of operating a wireless emergency stop system are also disclosed.

A sensor node with a mounting assembly and methods of using the same for affixing a sensor node to a machine to detect, isolate, and diagnose machine faults are discussed. An exemplary mounting assembly includes a base with a substantially centered through hole, and a fixation member operatively to pass through the through hole and engage the base. The sensor node includes a circuit board with circuitry to sense information of machine characteristic. The circuit board defines a guide hole concentrically aligned with the through hole on the base to allow the fixation member to pass through said holes. The base can be fixed directly to the machine by the fixation member, or via a mounting pad. A network of sensor nodes may communicate with a cloud-based computing device that provides a cloud-based service to detect a machine fault or to diagnose a fault type.

Processing systems and methods for receiving captured data of a data source attached with an expression of a relationship between the data source and a well construction system. The expression of the relationship between the data source and the well construction system is matched with an expression in a relationship descriptor including a description of a well construction system physical layout. The relationship descriptor also includes respective expressions of relationships between data sources and locations, equipment, and/or components of the well construction system. The expression in the relationship descriptor is one of the respective expressions. Secondary information is determined based on the captured data and the matched expression in the relationship descriptor.
