Re: Case sensor
Not Computer related but one of the engineering companies that I worked for had a Refrigeration department which did installs and maintenance of commercial equipment and the occasional domestic job when work was slow.
Some of the fridges used a coolant that would on occasion separate out and lose effectiveness. This was fixed by loading the fridge into the back of the works van and going for a drive around The vibration / acceleration / deceleration would churn everything up and hey presto one working fridge.
