A process for identifying the location of a break in a scan chain in real time as fail data is collected from a tester. The membrane is responsive to acceleration forces and is configured to produce a signal as a result of deflections in the membrane caused by acceleration. A control voltage source controls a DC level control circuit within the video amplifier such that the video signal is amplified and DC level shifted to align the video signal with down stream circuitry. The relevance measure is used to weight the data associated with each of the words in the task-independent training data. Purge air first enters the coating material flow path after the purge air enters the handgrip portion. The sleeve is pivotal between a first position which covers the device and a second position which exposes the device.
