Before I read the next response from Gil, I noticed that the human nervous
system satisfies these conditions.
I was thrown by "device," but once I started thinking outside the brain, it
made sense to me.
This did not occur to me until I saw the list of questions that Gil
compiled.
event-based (synapses firing, triggers from sensors, receptors, etc.)
embedded and network for sure
concurrency intensive operations for sure (thinking about coordinated
activity among the many functions of the human body)
minimal hardware requirements (hard to interpret here, depending on how we
split hairs on what constitutes hardware: excluding wetware, meatware,
what-have-you, the condition is satisfied).
I wouldn't say there was a TinyOS, but that wasn't described as one of the
requirements,actually -- only that it require minimal hardware!

Subject: RE: [unrev-II] A small quiz
The lack of context in this sentence leads the reader to make a number of
assumptions which very often are implicit. We can see that answers range
from the brain to multi-tasking operating systems.
Since many possible contexts exist, it is tempting to use an IBIS
discussion. I started a text bases discussion reproduced below. I ran out of
time and inspiration after a while and since IBIS is supposed to be
collaborative, this could be taken on by others. Notice however, that Henry
didn't ask what device X is, but what device X does. The answers, including
mine at first, focused on what the device is. What can we learn from this?
Device X "is an event based operating environment designed for use with
embedded networked sensors. It is designed to support the concurrency
intensive operations required by networked sensors with minimal hardware
requirements."
Question: What do you think Device X does?
Question: What is "an event based operating environment"?
Idea: could we replace environment with system?
Argument: No difference between this device and Windows, MacOS,
Linux
Question: What are "embedded networked sensors"?
Question: embedded in what?
Idea: In kitchen appliances
Idea: In cell phones and PDAs
Question: What's a networked sensor?
Idea: A device that gives some information about the
environment and is linked with other sensors
Question: Why do we need networked sensors?
Question: Why it is so especially proficient at doing it?
Idea: Because whoever promotes this device claims that sensors need
minimal hardware to be networked through this device.
Question: How can we make sure this claim is valid?
Question: What are the competing products for this device?
Question: What are the consequences of using this device?

Nice and warm, Eric.
