My Monkeys story concerns a Bosch instant-on hot water (natural gas) heater, which was made in Portugal, of all places.
The thing needs pampering … the electronics and solenoid need pre-warming with a light bulb for an hour or so before usage, now accomplished with a timer. Even then, it doesn’t work more than 80 percent of the time.
The interim solution has been to install a small five-gallon electric tank inline but AFTER the Bosch, which has a number of benefits, such as eliminating the filling of the hot water lines with cold water every turn-on (as it takes about 10 seconds of the tap running full in order
to activate the Bosch). Thus quick on-and-off usages of hot water (such as brushing ones teeth, rinsing hands, etc) don’t result in pulses of hot and cold water.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
