    Abstract: In one embodiment, a data processing device includes power port units for connection to network devices. Each power port unit is selectively configurable to operate as either (i) a Power Source Equipment port unit to provide power to a network device, or (ii) a Powered Device (PD) port unit to sink power from a network device. The device also includes a processor. In response to a power supply failure, the processor is operative to poll at least two network devices to determine if they are able to supply power, receive a response from each of the at least two network devices, and configure at least two power port units as PD port units to sink power from the at least two network devices. At least part of the received power is transferred from the at least two power port units via a power summing node to at least one local load.

    Abstract: Techniques are presented herein to operate a light fixture as in an emergency mode in order to verify that the light emitted by the light fixture when operated in the emergency mode complies with emergency operating policies, as well as to detect failures. The light emitted by the light fixture in emergency mode may be measured and adjusted to optimize the runtime of the light fixture in the emergency mode. The light fixture is connected to a lighting control system via a control network which supplies electrical power to charge an onboard battery of a light fixture and to operate the light fixture. The light fixture may be caused to operate in the emergency lighting mode when a main electrical power supply is interrupted or when performances of the light fixture and of the onboard battery are tested.

    Abstract: In one embodiment, a plurality of digital displays is connected to a backup power source and to a control computer having a processor and a memory. The memory is configured to communicate with the processor and has instructions that, in response to execution by the processor, cause the processor to determine if an emergency exists. If it is determined that an emergency exists, the processor will send a signal to the plurality of digital displays that includes instructions for the digital displays to enter an emergency mode.

    Abstract: Presented herein are methodologies to on-board and monitor Internet of Things (IoT) devices on a network. The methodology includes receiving at a server, from a plurality of IoT devices communicating over a network, data representative of external environmental factors being experienced by individual ones of the plurality of IoT devices at a predetermined location; generating, using machine learning, an aggregated model of the external environmental factors at the predetermined location; receiving, at the server, a communication indicative that a new IoT device seeks to join the network at the predetermined location; receiving, from the new IoT device, data representative of external environmental factors being experienced by the new IoT device; determining whether there is a discrepancy between the external environmental factors of the new IoT device and the aggregated model; and when there is such a discrepancy, prohibiting the new IoT device from joining the network.
