An approach is provided in which an emergency electrical distribution system detects an environmental alert invoked by an environmental sensor located in a particular location of building structure. The emergency electrical distribution system selects specific electrical source connections in proximity to the environmental sensor and, in turn, terminates electrical power to selected specific electrical source connections.

An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.

Disclosed is the glove worn by a user for incapacitating an individual. The glove includes a housing configured to cover palm and fingers of the user, the housing having a palm side layer for covering the front part of the hand and a backside layer for covering the back part of the hand; a circuit control unit configured on the backside layer having an anesthesia electrical wave generator for generating anesthesia electrical wave for incapacitating the individual; a power source configured on the palm side layer to power the circuit control unit; wherein the palm side layer having a first cutting resistance layer to protect the user's hand from foreign particles; a flexible electrode layer configured on at least one portion of the first cutting resistance layer to transfer the generated anesthesia electrical wave received from the anesthesia electrical wave generator to the individual; a pressure sensor configured beneath the cutting resistance layer to activate the flexible electrode layer only on exceeding pre-stored pressure value while grasping the individual by the user; and a first knitting cloth layer configured to be the innermost layer next to the palm of the user; wherein the backside layer having a backside leather layer configured to protect user's hand; and a second knitting cloth layer configured to be the innermost layer next to the back of the hand of the user.

A shut-off circuit interrupts the flow of power to the system circuit of a portable device, when liquids are detected within the portable device. Liquid sensors are placed proximate to the ports of the portable device. The ports may admit the flow of liquids, so the liquid sensors may detect the passage of liquids into the portable device. If the liquid sensors detect liquids entering the portable device, a shut-off circuit interrupts the flow of power from the battery to the system circuit.

A protection monitoring system is provided that includes a protection fault handler. The protection fault handler includes a protection fault indicator. The protection fault handler is configured to activate the protection fault indicator upon indication of a protection fault signal. Moreover, the protection fault signal is indicative of a critical fault which has occurred in a protection system monitored by the protection monitoring system. The protection monitoring system also includes a user inhibit handler. The user inhibit handler includes a user inhibit indicator. Moreover, the user inhibit handler is configured to activate the user inhibit indicator upon indication of a user inhibit signal. Furthermore, the user inhibit signal is indicative of a user-enabled alarm inhibit or a user-enabled bypass.

A moisture sensor includes one or more electrodes and sensor circuitry configured to detect the presence of moisture by detecting a change in an electrical measurement of the one or more electrodes. In response, the sensor may signal a component to perform an action. In some examples, capacitance and/or resistance between a pair of electrodes may be monitored, such as a pair of electrode sheets or meshes positioned in passage of a device that are separated by a gap. In various examples, a first electrode may be mounted cantilever to a second electrode and the presence of moisture between the electrodes may pull a free end closer to the second electrode. In some examples, the presence of moisture may cause bridging of a gap between two or more electrodes to complete or corrosion of a portion of an electrode to result in a change of resistance that can be detected.

This application relates to a moisture ingress sensor. In particular, this application relates to a moisture ingress sensor that can detect liquid ingress into an electronic device. The moisture ingress sensor can include a resistor, an N-channel MOSFET, an operation amplifier, comparators, and an AND logic gate. The moisture ingress sensor is configured to provide a lower power means for accurately detecting moisture in an electronic device. Multiple areas of the electronic device can include the moisture ingress sensor in order to optimize the detection of moisture for at a variety of regions of the electronic device. Additionally, the electronic device can record signals from the moisture ingress sensor and shut down components of the electronic device that could be affected by the detected moisture. Furthermore, the moisture ingress sensor can be tuned to detect one or more types of liquids.
