Now, this is just over the top really. Lawyers are very strange form of life on Earth (and beyond), i just get US 7750634 (H3Tec), and i have to say this is one of the most pointless texts i have chance to read so far (ok. USPTO have lot to offer, but this is among top ten for sure).
Frequencies given on page 19 are in MHz, not Hz, (and referenced to 2.3487 T field) it is easy to miss 6 orders of magnitude, just happens sometime. Nice figures of PCB, whit silkscreen and all, for something that can be cable modem or development system or...never mind. It uses "DSP processor chip, such as an AD 9850 chip in the SHARC series of chips produced by Analog Devices" (p.20), and "the frequency generator may be a chip such as an AD9850-CMOS, 125MHz Complete DDS Synthesizer manufactured by Analog Devices" (p.21). Somewhat unusual design choice, maybe just typo, or someone at AD drinks too much. But this is minor issue. Then goes this:
"The detection module uses the generated signal to create an excitation field and then may monitor for a corresponding elemental response coming from the target substance" (p.20) Nice, it can create very small intensity rapidly diminishing electric field between rods, EM radiation at these low frequencies will take something sized like submarine communication facility. Maybe ten miles long dowsing rod can help, not exactly handheld, but who care...NMR stuff not working like this anyway! In this patent, one small secret is undisclosed, part of circuit that will:
A. Produce switchable homogenous magnetic field of couple thousand Gauss over large area, to be used as a "polarizing field", or
B. Some controlled method to turn off Earth's own magnetism, and then listen to precession frequency.
(and, naturally, even then thing will not work)
And so on... What is the average cost of US patent procedure anyway? (I need sponsors to patent WARP drive, but i guess guys at USPTO already have few dozens )
Things like this will never end, ignorance is unbeatable, and its abundance starts to frighten me. Code red: C.R.A.P.
