摘要： A method of diagnosing a pneumatic system that (1) pressurizes the system to a first inflation pressure, (2) ceases the pressurizing for a settling-in time period, (3) measures a settled-in pressure after the settling-in time period, (4) measures a decayed pressure after a decay time period, (5) determines a determined rate of decay of the pressure in the system over the decay time period, and (6) compares the determined rate of decay to a first stored decay rate.

摘要： The invention relates to a method for detecting leakage of a hollow component, comprising the steps of sealing said hollow component (1, 31), creating a pressure difference P1 and P2 between said hollow component interior and an adjacent compartment/enclosure (2, 32), putting a tracer gas in one of the hollow component or said compartment/enclosure, waiting for an enriching time T and then carrying out a step of transferring, via a non-selective or selective restriction (6, 7; 49), the content of said hollow component or said compartment/enclosure (2; 32) into which tracer gas has not been put, in order to concentrate, in a volume downstream of said restriction (6, 7; 49), the tracer gas that said content may possibly contain, and then in looking for the presence of tracer gas in said volume. The invention also relates to an installation for implementing the method.

摘要： Systems and methods of detecting leakage and other issues with electrical battery housings are provided. By using an air compressor to alter the air pressure within a battery housing, a processor may detect an abnormal rate of change in the air pressure within the battery housing as compared to a rate of change of an ideal battery housing.

摘要： A device is disclosed herein. The device comprises a housing, a gas, an antenna, and a control module. The housing defines and hermetically seals an interior cavity. The gas is contained within the interior cavity of the housing at a pressure greater than atmospheric pressure. At least a portion of the antenna is within the interior cavity of the housing. The control module is operably coupled with the antenna to transmit an incident radio wave into the interior cavity of the housing and receive a reflected radio wave within the interior cavity of the housing. The control module is configured to determine a resonance frequency of the interior cavity of the housing based on, at least partially, the reflected radio wave, and determine the pressure of the gas contained within the interior cavity of the housing based on, at least partially, the resonance frequency of the interior cavity of the housing.

摘要： This application describes methods for responding to a storage vessel leakage event and the implementation of one or more assemblages of components to provide remediation of the leakage event. This application also describes methods of teaching storage vessel leakage remediation for responders and how to use the method of responding to storage vessel leakage event in combination with the one or more assemblages of components.

摘要： Disclosed is a bag including: a first envelope having at least one fill and/or discharge orifice for a biopharmaceutical fluid and a fill and/or discharge tube associated in a fluidtight manner with the fill and/or discharge orifice, a second envelope within which the first envelope is located, and a spacer element. The first envelope, the second envelope, and the spacer element form a coherent whole, in particular during use of the bag, and the fill and/or discharge tube traverses the second envelope by a fluidtight connection, the fill and/or discharge inlet being located outside the second envelope.
