<p>A portable ionizer 100 worn in the vicinity of the human face (for example, by a necklace 12) diffuses negative ions in the facial area of the wearer. As a consequence of this capacity to focus the ion flux, fewer ions trust be produced by the source to obtain the benefit to the wearer. The necklace ionizer 100 is given a pleasing external appearance and a useful purpose, such as an advertising display 2. The negative ions are generated by a high-voltage alternate frequency ion generating needle 8. A control module including a power management system, a transformer, and a multiplier is used to minimize power drain on a rechargeable battery 6. Other features of the power management system include an LED display shut-off, battery voltage cutoff, management of needle life, and management of power supply drain time through frequency modulation or voltage control. A control interface and a method of advertising a service are also claimed.</p> |
