Yes, one of my guesses was 'Threshold Sensitivity'... but to me that sounds
redundant. You set a threshold or you set a sensitivity, a threshold
sensitivity doesn't seem right to me, but then again this was 60+ years ago,
maybe the concepts were a bit different. I am kind of hoping for a bit
better identification of what it might be off of.
