If I'm not mistaken, if you patent a device (aparatus) you can't be so
vague in the patent wording and have to submit a prototype too... 
doesn't that mean that if my device doesn't in any way resemble the
prototype I'm clear from patent infrigement?

The isssue on patenting an algorithm/software (not a device) is
a completelly different issue as we know.
