A fluid chamber is defined between the fluid barrier and the outlet, and the apparatus comprises means for detecting a change in condition in the fluid chamber indicative of a change in volume of the seal element of the sealing device.

The disclosure relates to a method for determining a size of a leak in a fuel tank system. The method includes: starting an internal combustion engine; calculating a stoppage time for a vehicle and/or a temperature difference between the fuel in the fuel tank system and the environment; and checking whether at least one of a plurality of diagnostic conditions is fulfilled. A first diagnostic condition is fulfilled when the stoppage time is longer than a predetermined minimum stoppage time. A second diagnostic condition is fulfilled when the temperature difference is smaller than a predetermined maximum temperature difference. Additionally, when at least one of the plurality of diagnostic conditions is fulfilled, the method includes: evacuating the fuel tank system; recording a time profile of the pressure in the fuel tank system; and determining the size of a leak based on the recorded time profile of the pressure.

An inspection method for inspecting the water resistance of an electronic device is provided, including providing a vacuum generator, using the vacuum generator to pump air out of the electronic device, stopping the pumping of air out of the electronic device when the air pressure in the electronic device is less than a predetermined pressure value, measuring the air pressure in the electronic device as a first pressure value after the pumping of air out of the electronic device has been stopped for a predetermined time, calculating the pressure difference D by subtracting a second pressure value from the predetermined pressure value, calculating the pressure difference d by subtracting the second pressure value from the first pressure value, and determining whether the electronic device is waterproof or not according to the pressure differences D and d.

The present disclosure provides systems and methods for controlling a semiconductor manufacturing equipment. A control system includes a sensor unit capturing a set of data related to a gas pressure in the equipment, a sensor interface receiving the set of data and generating at least one input signal for a database server, and a control unit. The control unit includes a front end subsystem, a calculation subsystem, and a message and feedback subsystem. The front end subsystem performs a front end process to generate a data signal. The calculation subsystem performs an artificial intelligence analytical process to determine, according to the data signal, whether a malfunction related to the gas pressure has occurred and generate an output signal. The message and feedback subsystem generates an alert signal and a feedback signal according to the output signal and transmits the alert signal to a user.
