For power, if we can get a low power laser diode Tx. circuit, then we
can experiment on the use of a split transformer where the primary and
its core is in the hand held unit and the secondary and its core is in
the fixed Tx. unit. When the two cores meet, a high frequency
oscillation in the primary ferrite core, passes the electromagnetic
field into the secondary core to generate just the power required to
transfer the zipped package. I recollect, the EHT transformer of the B/W
television runs on the 15625 Hz. horizontal frequency and 4 to 5 turns
of ordinary wire around its ferrite core can generate voltage for the
CRT's filament.
I was looking for working solutions and found that some one else too has
thought of this technique in a similar way.
