摘要： 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.

摘要： 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.
