The invention relates to an accumulator module (26) comprising a moisture-proof housing (28), in which a plurality of accumulator cells (31) is disposed, the contacts of which are electrically interconnected and which are routed to external contacts (30) of the accumulator module (26) disposed at the outer face of the housing (28). To be able to detect a short circuit between the external contacts (30) of the accumulator module (26) in the simplest and most efficient manner possible, it is proposed that a protection device (35) is disposed inside the housing (28), which protection device comprises a detection device (36), which is designed to detect a short circuit between the external contacts (30). Furthermore, the invention relates to a swimming and diving aid (10) comprising such an accumulator module (26).

An electronic device includes a circuit board having a signal detection terminal disposed on a first surface thereof and a ground terminal disposed on a second surface thereof and extending vertically so that the first surface and the second surface face each other in a horizontal direction, a monitoring terminal connected with the signal detection terminal, and a microcontroller unit (MCU) determining whether there is submersion by monitoring a voltage at the monitoring terminal. According to the present embodiments, it is possible to prevent hypersensitivity-induced misdetection due to condensation and dew. It is also possible to stepwise respond to submersion and determine whether the monitoring circuit normally operates to precisely detect submersion.

An electronic device according to various embodiments of the present invention may comprise: a housing; an interface connected to the housing or exposed through the housing and comprising at least one configuration channel (CC) pin; a circuit disposed inside the housing, comprising a current generator and a comparator, and electrically connected to the interface; a processor disposed inside the housing and operatively connected to the interface and the circuit; and a memory operatively connected to the processor. The memory cause the processor, when executed, to detect moisture corresponding to the at least one CC pin on the basis of the comparator while the at least one CC pin is connected to the current generator and to control at least one switch disposed between the current generator and the at least one CC pin, in response to detection of the moisture, thereby conducting switching such that the at least one CC pin is not connected to the current generator. Other embodiments are also possible.

A telecommunications cabinet (100) for enclosing telecommunications equipment (110) of a telecommunications network, the telecommunications cabinet comprising: an electric water pump (140); a water detector (160), wherein the water detector is configured to cause activation of the electric water pump upon detecting water; a power supply (150) for powering the electric water pump; and a fluid conduit (170), coupled to the electric water pump, extending from within the cabinet to an outside of the cabinet via an aperture (180) in the cabinet so as to convey water out of the cabinet.

A method for protecting a server from damage by a liquid leak from a liquid-cooling unit of the server is provided. The server further includes a liquid leak sensor unit, a programmable logic circuit, and a power supply unit that supplies main power and standby power for the server. When a liquid leak is detected, the liquid leak sensor unit generates a main-power-off signal to the programmable logic circuit that causes the power supply unit to stop outputting the main power accordingly. The liquid leak sensor unit sends a total-power-off signal to the power supply unit to stop supply of the standby power after the power supply unit has stopped outputting the main power.

Provided is an electric connection box with which proactive measures can be taken by liquid inflow monitoring. The electric connection box includes a housing where an electronic component is mounted. The housing is provided with a detection part detecting liquid inflow.

An electronic device comprising a Printed Circuit Board (PCB), a battery for supplying power to the PCB and at least one moisture detection sheet mounted on the PCB and the PCB shuts off power from the battery in response to detected electrical current conduction via the at least one moisture detection sheet.

Methods and apparatuses for detecting when an electronic device, preferably a portable electronic device (PED) in some embodiments, has been exposed to moisture, and inhibiting the flow of electrical power to the electronic device when the moisture is too high or increasing too fast are disclosed. Embodiments sample air within the device, measure the moisture in the sampled air, inhibit the connection of electrical power to the device if the moisture exceeds a threshold, and permit the connection of electrical power to the device if the moisture is below a threshold. Some embodiments measure the moisture in the ambient air to improve effectiveness. Other embodiments allow resetting of a tripped condition. Other embodiments include constant sampling of air from within the device to assist drying, and inhibiting application of power to the device until the device is sufficiently dry. Still other embodiments interrupt power from the battery within the device.

Embodiments are directed to apparatuses used with a computer-implemented method for controlling power flow to an electronic device, including: receiving a transmission from a service processing device, the transmission to trigger an open switch between the electronic device and a power supply; and causing an open switch to occur through use of an interlock mechanism. Embodiments provide a temperature-driven interlock mechanism and moisture-driven interlock mechanism.

Systems, devices and methods for sensing moisture within an electronic device are disclosed. A device may include a housing and a display defining and exterior of an electronic device and an interior of the electronic device. Further, the device may include an integrated circuit (IC) within the electronic device and comprising a control element. The device may also include a moisture sensor such as an inductive sensor, a capacitance sensor, or both. The moisture sensor, which may be part of the IC, together with the control element may sense moisture within the electronic device
