    Abstract: A thermal monitoring system includes at least one of an infrared sensor and a plurality of infrared sensors arranged in an array. Each infrared sensor has a resolution including a plurality of pixels. A controller is configured to create a thermal image of an area to be monitored based at least in part on the plurality of pixels of each infrared sensor. A thermal monitoring assembly includes an electrical panel including a plurality of electrical components located within the electrical panel. The at least one of an infrared sensor and the plurality of infrared sensors arranged in an array, either alone or in combination with additional sensors, are located inside the electrical panel. Methods of monitoring various parameters including a temperature of the plurality of electrical components located inside the electrical panel are also provided.

    Abstract: A control system for hazardous environments decreases flame paths, decreases punctures to the control system when installing interfaces, and increases safety. The control system may be characterized as a “one size fits all” controller that is able to automatically recognize a plurality of user interfaces. The controller has an enclosure to which the interfaces can be attached. The interfaces may interact with control electronics wholly contained in the enclosure using a variety of “wireless” mechanisms. Such mechanisms include reflecting light waves, infrared (IR) communication, radio-frequency identification, inductive coils, short-range wireless communication, camera images, piezoelectricity, and magnetism, and the like. The interfaces may include switches, indicator lights, smoke detectors, and the like.

    Abstract: A system includes a hot wire and a neutral wire configured to establish a closed circuit between a power source and a load. The system further includes first and second transformers as well as a sensor. The first current transformer is coupled to the hot wire and is configured to introduce a first test current, with a first polarity, into the hot wire. The second current transformer is coupled to the neutral wire and configured to substantially simultaneously introduce a second test current into the neutral wire. The second test current has the same polarity as the first test current. The sensor is configured to sense an asymmetry between the first and second test currents and is further configured to cause interruption of the closed circuit upon sensing the asymmetry.

    Abstract: An electrical system can include a diagnostic device that generates a first test signal. The electrical system can also include multiple energy transfer links coupled to the diagnostic device, where the first test signals flows through a first subset of the energy transfer links. The electrical system can further include a first monitoring device coupled to the first subset of energy transfer links, where the first monitoring device receives the first test signal from the diagnostic device through the first subset of the energy transfer links. The electrical system can also include a first electrical device coupled to the first monitoring device. The first monitoring device can implement a first test procedure based on the first test signal, where the first test procedure helps determine a first condition of the first electrical device.

    Abstract: A device can include multiple light loads, where each light load includes at least one light source. The device can also include multiple switches coupled to the light loads. The device can further include a controller coupled to the switches, where the controller actively operates the switches multiple times within each cycle to control delivery of power to the light loads. Active operation of the switches by the controller is performed on a dynamic schedule, where the dynamic schedule is based on multiple environmental conditions, and where the controller bypasses a forward voltage of the light loads when actively operating the switches.
