Title: A biofuel cell using wastewater and active sludge for wastewater treatment
Inventor: PARK HYUNGSOO
IPC: H01M8/16
Filed: 2000-03-17
Abstract: The present invention provides a biofuel cell using wastewater as a fuel.  Electrochemically active microorganisms present in wastewater and active sludge sued in the present invention oxidize organic substances present in wastewater. Electrons generated from the oxidation are discharged outside of the microorganism cell and transferred directly to the electrode, thereby allowing electric current to be generated while allowing wastewater to be purified. The biofuel cell using the electrochemically active bacteria according to the present invention allows an electric energy of up to 0.22 mA  to be generated, and also enables COD of the wastewater used as a fuel to be decreased from 1900 ppm to 55 ppm. Moreover, an efficiency of the biofuel cell is varied depending on the king and concentration of wastewater.

Inventor: PATTERSON HUBERT A
IPC: G08B13/24
Filed: 2001-08-21
Abstract: An electronic article surveillance (EAS) system and method utilizing two transmitted signals to generate and detect a marker signal is provided. The first signal is set at or near the resonance of the marker so its energy can  be transmitted and stored in the marker. The second signal is a low frequenc y magnetic field that changes the resonant frequency of the marker. Because th e marker's resonant frequency is constantly varying in repsonse to the low frequency magnetic field, the marker's response to the first transmitted signal also changes. As a result, the marker performs a modulation on the first transmitted signal. Detection of a sideband of the modulated signal indicates the presence of the marker within an interrogation zone formed by the two transmitted signals. Multiple interrogation zones can be implemented  by transmitting multiple low frequency signals, one low frequency signal for  each interrogation zone.
