A method and system for vacuum chamber integrity verification after chamber maintenance or venting. The method includes a computing system causing a measurement cycle that includes causing a pump to pump down pressure of the vacuum chamber for a set duration of time or to a target pressure; causing an isolation valve to isolate the vacuum chamber; receiving sensor data from an optical emission sensor; and analyzing the sensor data to determine whether the sensor data satisfies one or more sensor data criteria. The method further includes, the computing system, causing one or more repetitions of the measurement cycle until the sensor data meets the one or more sensor data criteria. The method further includes analyzing the sensor data that meets the sensor data criteria to determine at least one of vacuum chamber leak rate or vacuum chamber moisture content. The system includes the vacuum chamber, pump, isolation valve, optical emission sensor, and computing system.

The present invention relates to a device and method for inspecting and monitoring the seal integrity and/or seal strength of sterile medical packages, and more particularly, to a medical package sealer device having integrated vacuum decay or differential pressure testing allowing for real-time seal strength or integrity testing of each medical package sealed by the device. The present invention may also be described as a method for sealing and testing medical packages. By communicatively coupling the mass flow meter(s) to the processor of the herein disclosed device for sealing medical packages with integrated real-time seal integrity vacuum decay or differential pressure testing, each sealed package may be tested for a quantitative measure of air flow, and the quantitative measure of air flow may be recorded and stored in a searchable database, or used to provide a notification to an operator or to stop operation of the system. In this way, 100% of the medical packages sealed may be inspected for deviation from an established standard.

The present invention relates to a device (1) for detecting leaks for a motor vehicle battery pack, said device (1) comprising:a pneumatic circuit (100) comprising a plurality of valves (V.sub.1, V.sub.2, V.sub.3) and a pressure sensor (106);at least one connector (7) allowing to connect said pneumatic circuit (100) to at least one element of the battery pack; said device (1) being configured to carry out at least one procedure for detecting leaks on at least one element of the battery pack via said pneumatic circuit (100) and said connector (7).

The invention relates to methods for inspecting objects fed in a continuous flow, in particular packages or components, wherein an inspecting body is guided along an inspection segment together with an object and a response to an inspection of the object is detected by means of a sensor in order to determine if the object meets a quality criterion, in particular is tight or leaky or true to size or functional.

A system and method for measuring integrity of flexible containers is disclosed. The system uses a low mass flow transducer to monitor the flow of fluid into the flexible container. Based on this flow rate, the existence of an orifice in the flexible container may be detected. The system also includes a second flow path to the flexible container to allow for faster fill times. Greater flow rates are achieve through the use of a second high mass flow transducer or a calibrated bypass path. These alternate paths allow greater flow rates until the flexible container is determined to be nearly full, at which point all flow passes with the low mass flow transducer.

An apparatus (100) for testing suction cups (138) mounted on a track (162) is disclosed. The apparatus (100) comprises a base (102) comprising a first surface (104) and a second surface (106) opposite the first surface (104). The apparatus further comprises ports (108) penetrating the base (102) from the first surface (104) to the second surface (106) and vacuum sensors (112) pneumatically coupled to the ports (108). The ports (108) in the base (102) are arranged in a geometric pattern (110).
