A leak detection and recovery system for use with DRA equipment. The system is intended to reduce the risk of a chemical release into the environment, namely the soil, ground water, and waterways. The system may provide clean collection of leaked DRA, early detection of DRA leaks, immediate notification of DRA leaks, and re-use of leaked DRA through clean recovery with no hazardous waste disposal.

A battery assembly heat insulating container includes a box body and a lid body. The box body has an opening on its upper surface, and contains a battery module formed by connecting a plurality of battery cells in series or in parallel. The lid body is placed on the upper surface of the box body. The battery assembly heat insulating container is adapted to provide heat insulation between an external space and an internal space formed by the box body and the lid body and configured to contain the battery module. A circuit member configured to detect leakage of active material from the battery module is provided at the bottom of the box body.

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.

Methods and apparatus for detecting and measuring gas flow are disclosed in which lidar distance information, acquired during the detection of gas using a lidar sensor, is used together with prevailing wind data to determine local wind data for the leak location. This local wind data, which may comprise one or more vectors or a 3D wind model, is used in the determination of flow rate.

A leak detection system for detecting leaks in pressurised containers, the system comprising a leak test conveyor for moving each container and an accumulation tunnel through which the leak test conveyer extends, wherein the accumulation tunnel and the leak test conveyer together define at least one enclosed accumulation volume, each enclosed accumulation volume being sized to accommodate only a single container, thereby to allow gas leaking from the single container to accumulate, and a gas sensor for sensing accumulated leaked gas from the single container.

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.

A device (1; 2; 3; 4; 5) is provided for carrying out an integrity test on a sample of disposable components. The device has a medium chamber (10) with an inner chamber (11) that is bounded to the outside, for the purpose of receiving a culture medium. The device also has a sample holder (20) in which the sample (100) can be arranged in such a way that the sample (100) at least partially bounds the medium chamber (10) to the outside. The medium chamber (10) has a vent line (19) that is arranged on a side of the medium chamber (10) facing away from the sample holder (20).
