Abstract: The disclosure describes techniques for detecting a crack or defect in a material. The technique may include applying an electrical signal to a first electrode pair electrically coupled to the material. The technique also may include, while applying the electrical signal to the first electrode pair, determining a measured voltage between a second, different electrode pair. At least one electrode of the second, different electrode pair is electrically coupled to the material. The technique may further include determining a corrected measured voltage by suppressing a thermally induced voltage from the measured voltage and determining whether the material includes a crack or other defect based on the corrected measured voltage.

Abstract: An armor piece may include a tested material. The armor piece also may include a plurality of electrical contacts distributed about and electrically connected to the tested material. The armor piece further may include a non-volatile memory (NVM) device. The NVM device may be hardened against exposure to x-ray radiation. The NVM device may be configured to store control voltages associated with respective electrical contacts of the plurality of electrical contacts.

Abstract: A measurement system may include a set of drive electrical contacts including a force electrical contact and a return electrical contact electrically coupled to a tested material, a measurement electrical contact electrically coupled to the tested material, a return node, a voltage source, and a control module. A circuit path between the voltage source and the return node may include a fixed resistor and the tested material. The control module may be configured to cause the voltage source to apply a voltage signal to the force electrical contact, cause a voltage drop across the fixed resistor to be measured, cause a measured voltage to be measured using the measurement electrical contact, determine a measured equivalent impedance of the tested material associated with the measurement electrical contact based on the voltage drop across the fixed resistor and the measured voltage, and determine whether the tested material includes a crack or other defect based on the measured equivalent impedance.

Abstract: A data communication apparatus, system, and method are described. The data communication system comprises a transceiver disposed on an entrance port to an enclosure, such as an underground enclosure. The transceiver includes a housing, the housing mountable to the entrance port, wherein the transceiver is configured to communicate with a network outside of the underground enclosure. The data communication system also includes a monitoring device disposed in the underground enclosure that provides data related to a real-time condition within the underground enclosure. The data communication system also includes a sensor analytics unit to process the data from the monitoring device/sensor and generate a processed data signal and to communicate the processed data signal to the transceiver.
