Apple files patent for true wireless charging technology
Authored by: tinkerghost on Saturday, December 01 2012 @ 07:58 AM EST
The patent for communications satellites was denied based on Arthur C Clarks
books description of them.

You patented WHAT?!?!?!

National Electric Code
Authored by: artp on Saturday, December 01 2012 @ 11:26 AM EST
Power and signal wires shall be run in separate conduits and
separate chases. This reduces the chance of interference
between the two. It doesn't bother the power lines at all,
but it introduces a whole bunch of undesirable gibberish
into the signal lines.

Also, the Instrument Society of America mandates twisted
pair wires for signal transmission in order to reduce cross-
talk between different sets of wires, which could have
disastrous results for whatever is waiting for those
signals.

So this technology (?) is already enshrined in our nation's
standards. We just called it a bug before. I sure wish that
the USPTO could read.

Apple files patent for true wireless charging technology
Authored by: Ronny on Saturday, December 01 2012 @ 11:35 AM EST
The key words here were "Nicola Tesla", not "Robert
Heinlein".

You are right that simply describing a problem (for example, wireless
electricity transmission) does not make a solution to that problem
unpatentable.

Tesla demonstrated wireless transmission of electricity in the nineteenth
century. Demonstrated in that he had a working implementation, based just as
Apple's patent on electrical induction. (Apple call it Near Field Magnetic
Resonance, but that's just another term for the same thing.)

This doesn't render Apple's patent invalid, it just means that they don't have a
monopoly on wireless charging in general. From what I see of the patent, its
main contribution is that you can extend the "charging field" out to
some sort of external base station.

The Heinlein reference was to indicate that the technology was not merely old
when my grandfather was a twinkle in his mother's eye, but that the implications
of the technology have been long since been examined.

I do wonder how those who think that nearby power lines and mobile phones can
cause cancer would react to these devices.

Wireless charging has been around for years and is used in things like
pacemakers, as well as some home appliances such as electric toothbrush. The
difference with this is it uses near field RF energy. I don't know if that is
enough of a difference to make it a new invention. There's also the question of
efficiency in the power transfer. Generating RF, even at low frequency, and
coupling it to a receiver has efficiency issues which mean significant power is
wasted.

Actually the oldest reference to starship warp engines I have seen is from John W. Campbell Jr, The Mightiest Machine (1947) and Islands of Space (1956)

Heinlein didn't just mention waterbeds, he described how they worked, to
sufficient degree that someone "skilled in the art" could build one.
In _Expanded Universe_ (and maybein _Worlds of Robert A. Heinleim_, but I don't
have that), he describes not only how he invented it, but that his description
in _Stranger in a Strange Land_was sufficient to prevent it from being
patented.

Remember that Heinlein was also an engineer by trade.
