An electronic device includes a sensing unit, a storage, and a processor. The sensing unit detects whether the electronic device has entered a liquid, and upon sensing that the electronic device has entered a liquid, senses a number of environmental parameters of the liquid. The processor obtains the number of environmental parameters of the liquid from the sensing unit and determines whether any of the number of environmental parameters exceed a predetermined value, and judges, when any of the number of environmental parameters exceed the predetermined value, that a waterproof warranty on the electronic device is voided.

A system is provided for collection, detection and containment of leaked liquid. The system may include a spout connected to a liquid cooling manifold for channeling liquid. The system may also include a collection tray positioned under the spout and configured to contain the liquid from the spout. The system may further include a leak detection rope having a first end coupled to the liquid cooling manifold, a middle portion extending along the spout, and a second end placed inside the collection tray for detection of liquid.

In one embodiment, the disclosed apparatus is a process cooling-water isolation system used in a process tool. The system includes an isolation valve coupled between a water supply and an inlet of one or more components in a process-module water-cooling circuit. An open device allows cooling water to flow to the one or more components, while a close device prevents cooling water from flowing to the one or more components. At least one water-leak sensor is coupled to the close device to detect a water leak within the process tool. A check valve having an inlet port is coupled to an outlet of the one or more components, and an outlet port is coupled to a water-return reservoir. The check valve prevents water from back-flowing from the water-return reservoir into the one or more components. Other apparatuses and methods are disclosed.

A water heater includes a leak detection system that is integrated with the water heater. The leak detection system includes a channel that extends circumferentially around the water heater. In one example, the channel is built into the water heater. In another example, the channel is formed by a sensor bracket that is coupled to the water heater. Further, the leak detection system includes a sensor assembly that is configured to detect water that leaks from the water heater. The sensor assembly includes a leak sensor and/or a wicking tube. The wicking tube is disposed around at least a portion of the leak sensor. Further, the wicking tube is disposed in the continuous channel and extends circumferentially along the water heater to create a circumferential area of leak detection around the water heater.

A detector for a laboratory liquid distribution system is presented. A detector system for a laboratory liquid distribution system comprising such a detector, a laboratory liquid distribution system comprising such a detector and/or such a detector system, a laboratory automation system comprising such a laboratory liquid distribution system and a use of such a detector are also presented.

A sensor assembly for detecting material loss of a vessel transporting flowing media, the sensor assembly having at least one sensor positioned between a pair of annular plates such that the radially innermost surface of the sensor is in open communication with the flowing media. A series of parallel resistors spaced along the sensor and transmit a signal. As the material of the annular plates is worn away by corrosion and/or erosion, the outermost resistor becomes exposed to the flowing media and breaks the circuit as to that resistor, thus changing the signal.

An apparatus for detecting leaks in a battery includes a plurality of cells, each which include a pair of conductive leads bracketing a polymer seal, and a wireless measurement and communication chip (chip) configured to perform capacitive measurement, showing a change in capacitance when bridged by ionically conductive species or when a wick is suffused with an electrolyte.

In some respects, concepts disclosed herein generally concern systems, methods and components to detect a presence of a liquid externally of a desired primary flow path through a segment of a fluid circuit, e.g., throughout a cooling loop. Some disclosed concepts pertain to systems, methods, and components to direct seepage or leakage of a liquid coolant toward a lead-detection sensor. As but one example, some disclosed liquid-cooled heat exchangers incorporate a leak-detection sensor, which, in turn, can couple with a computing environment that monitors for detected leaks, and, responsive to an indication of a detected leak, invokes a task to control or to mitigate the detected leak.

A nonmetallic conductive geotextile and a geocomposite. The nonmetallic conductive geotextile comprises a geotextile and a nonmetallic conductive structure, the nonmetallic conductive structure comprising one of carbon nanotube, graphene, superconductive carbon black or a combination thereof, wherein the nonmetallic conductive structure may be conductive coating which is coated onto the surface of the geotextile; the nonmetallic conductive structure may also be a conductive fiber, and when producing the geotextile, the conductive fiber is added and connected into the geotextile to form a nonmetallic conductive blended geotextile; the nonmetallic conductive structure may also be a conductive sewing thread, and when producing the geotextile, the conductive sewing thread is sewn onto a nonwoven fabric at regular intervals to form a nonmetallic conductive geotextile; and the geocomposite comprises a geonet and the nonmetallic conductive geotextile bonded to one surface or two surfaces of the geonet.

A fluid measuring device includes a measuring head device having a measuring head with separated and electrically insulated electrodes and measuring head contacts each connected to a respective electrode. A measuring circuit includes terminal contacts each connected to a respective measuring head contact. The measuring circuit includes a current source for pulsed energizing of the measuring head connected to the terminal contacts.
