Abstract: This disclosure provides methods and systems for reducing congestion in RoCEv2 networks. The method is configured to operate large-scale in data centers on traffic flowing from a sender node to a receiver node. The method described has three stages: a fast start stage, a transition stage, and a regulation stage. In the fast start stage, the sender sends data to the receiver at a fast initial rate. This may continue until the receiver observes a congestion event. When this happens, the sender reduces the data transfer rate as the method enters the transition stage. From a reduced rate, the method enters the regulation stage, where the rate is increased using a combination of a feedback control loop and an additive increase multiplicative decrease (AIMD) algorithm.

Abstract: An augmented reality (AR) node location and activation technique for use in an AR system in a process plant or other field environment quickly and easily detects an AR node in a real-world environment and is then able to activate an AR scene within the AR system, which improves the usability and user experience of the AR system. The AR node location and activation system generally enables users to connect to and view an AR scene within an AR system or platform even when the user is not directly at an existing AR node, when the user is experiencing poor lighting conditions in the real-world environment and in situations in which the user is unfamiliar with the AR nodes that are in the AR system database.

Abstract: An intrinsically safe (IS) luminaire disposed in a hazardous environment provides visible light and serves as a primary, auxiliary, back-up, and/or charging source of IS DC power for external devices disposed in the hazardous environment, such as process control devices and equipment. The luminaire includes a power converter that converts received power into DC power, an IS barrier that converts the DC power into IS DC power native to or utilized by a recipient external device, and a power distribution port via which IS DC power is delivered to the external device. In some configurations, the luminaire monitors communicates statuses, alerts, and/or other information corresponding to delivering IS DC power to one or more external devices to a host and/or portable communication device. The luminaire may include multiple IS barriers of same and/or different IS ratings, and may dynamically control activation/deactivation of the IS barriers and/or usages thereof.

Abstract: A smart luminaire system in which a primary luminaire controls and/or communicates with a set of one or more secondary luminaires may be disposed in a hazardous environment, such as an industrial process plant, manufacturing facility, oil refinery, etc. The primary luminaire may send driving commands to the set of secondary luminaires via an analog portion of a hybrid wired communication interface, and the driving commands may cause a driver of a second luminaire to energize on-board illumination source(s) at various intensities. The primary luminaire may send and/or receive administrative messages to/from the secondary luminaires via a digital portion of its hybrid wired communication interface. The smart luminaire system may be a stand-alone system, or may communicate with a controller or back-end system via a wireless communication interface of the primary luminaire, e.g., to receive control instructions and/or to send consolidated administrative messages on behalf of the smart luminaire system.

Abstract: A luminaire network improves energy efficiency, reduces light pollution, improves the robustness of luminaire control, and reduces maintenance time and costs by implementing intelligent and selective lighting control. For example, the luminaire network may automatically control dimming, light activation, light deactivation, static or dynamic luminaire grouping, and luminaire group control by implementing a hybrid control scheme that accounts for (i) local or global fixed schedules (e.g., based on time of day, worker schedules, etc.), (ii) detected daylight, (iii) detected motion of workers, and (iv) feedback from luminaires in the luminaire network. Further, one or more electronic devices (e.g., mobile devices) may couple to the luminaire network and may facilitate easy monitoring, configuration, and manual control of luminaires in the luminaire network, even when remotely connected to the luminaire network (e.g., via the cloud).

Abstract: An example system includes an electrical enclosure. The electrical enclosure includes an identification data module, an electrical sensor, an enclosure environment sensor, and a pilot light module. The pilot light module includes (i) a pilot light and (ii) a communication module. The communication module is coupled to the identification data module, the electrical sensor, and the enclosure environment sensor. The communication module is configured to determine a visual communication signal based on information received from one or more of the identification data module, the electrical sensor, and the enclosure environment sensor, and drive the visual communication signal via the pilot light. The visual communication signal indicates one or more operational parameters within the electrical enclosure. The system further includes a client device configured to receive the visual communication from the pilot light.
