Thanks Derek, glad to see 4k data looks ok, I have a few questions before our meeting this evening:
1. Overall, after the HTHH test, the pump PQ curve “rotated” to a “higher flow lower pressure” shape, though the "area under curve” is probably similar to
initial test. This indicates that the actuator has changed shape— even after it’s been cooled down to room temperature. Any inspection data on this?
2. Have you plotted some "Q vs noise” or P vs noise” curves for these 20 pumps to see if there is a correlation between noise and performance?
3. Are pumps in this lot using a new batch of pzt material compared to previous 4core modules?
4. Have you ever tried to use one PZT core, and package it in both “machined” housing and “molded” housing, to confirm that the packaging of the
cores is indeed the cause of performance increase?
