Abstract

A method and device for determining the existence of a leak in a package includes generating an AC high voltage with DC high voltage offset in a circuit. A package is placed between an inspection electrode and a detection electrode, which are located within the circuit. The inspection electrode applies the AC high voltage with the DC high voltage offset to the package. Current flow through the package is then detected by the detection electrode. A detection board then processes the current flow and sends the processed signal to a programmable logic controller which determines if a leak is present in the package. If a leak is present, a signal is sent to a display to notify a user.

Abstract

The current invention mitigates the problem of incorrect determinations of leaking packages during vacuum decay leak detection testing. As described in this disclosure, a testing chamber used for vacuum decay leak detection testing is exposed to interferences when not under vacuum or at low pressure conditions between testing cycles. By measuring one or more exposure time intervals immediately preceding a present test cycle, it is possible to improve detection of leaking packages by adjusting raw measured pressure gathered during vacuum decay leak testing based upon the length of exposure times and create corrected pressure data used to improve vacuum decay leak detection.

Abstract

A method and system of testing for package leaks by a test system is disclosed. The test system includes a vacuum source and a test chamber in which a package is received for testing. A package is placed in the test chamber, and a vacuum is drawn on the test chamber by the vacuum source. A predetermined pressure level in the test system is detected, and based upon the detection of the predetermined pressure level, the test system determines when to stop drawing the vacuum. The test chamber is isolated from the vacuum source based upon the determination, and subsequently the test system detects the presence or absence of a leak in the package based on pressure measurements in the test chamber. A timer may be used to determine the delay in isolating the test chamber from the vacuum source after detection of the predetermined pressure level.

Abstract

An airborne ultrasonic testing system includes two sets of ultrasound transmitters and receivers, an ultrasound frequency generator, a computer analyzer, and a controller. The ultrasound transmitters and opposing receivers are fixedly mounted at oblique angles from a support. A seal-receiving slot is defined between the transmitters and receivers, and is sized to receive a sealed edge portion of a container to be tested. The ultrasound transmitters preferably emit respective ultrasound streams that encounter a top surface of a sealed edge portion of the container at an angle between approximately 0-45 degrees, and most preferably, approximately 45 degrees. The angle of ultrasound emission of the first transmitter may be inverse of the angle of emission of the second transmitter. The signal response of each pair of receivers can be processed individually or combined to produce a summary test result of the two measurements that eliminates systematic variation associated with material variation.
