Abstract
United States Patent No.6,754,472
Methods and apparatus for distributing power and data to devices coupled to the human body are described. The human body is used as a conductive medium, e.g., a bus, over which power and/or data is distributed. Power is distributed by coupling a power source to the human body via a first set of electrodes. One or more devise to be powered, e.g., peripheral devices, are also coupled to the human body via additional sets of electrodes. The devices may be, e.g., a speaker, display, watch, keyboard, etc. A pulsed DC signal or AC signal may be used as the power source. By using multiple power supply signals of differing frequencies, different devices can be selectively powered. Digital data and/or other information signals, e.g., audio signals, can be modulated on the power signal using frequency and/or amplitude modulation techniques.

What's the point of this patent?


To stifle the free use of very basic and trivial knowledge? To extort undue compensation from those that actually would solve the problem with a REAL working model that does something usefull?

Patents and their laws can be a real road block to inovation and progress. They hand them out like candy for the silliest things...
