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.
