Fascinating that there is a hand crank somewhere on the machine. However this example is a tiny bit off as the point of failure in all the cases they mention in the paper were external power. I was asking more about redundancies in the equipment itself.
- detaro 5y agoIf your machine relies on external power, that is something you must consider and design around.
- gillytech 5y agoFair point. I think this is cared for as all hospitals have backup power supplies and those supplies must be relied on. Last time I was in the hospital I saw red power outlets in the wall. I asked the nurse and she told me the red ones are hooked up to the emergency backup power.
- detaro 5y agoThere's almost guaranteed to be different levels to that too (e.g. allowed time for switch-over, interruptions, ... : emergency generators are far foolproof!), that need to be considered in the design. Emergency batteries in devices are not unusual.
