| 20100162780 | METHOD AND APPARATUS FOR DEPOSITING AGENTS UPON AND WITHIN BIO-CHAR - Methods and apparatuses for depositing agents relatively deep within pores of bio-char. Bio-char is first produced in an airtight oven by heating biomass feedstock. The bio-char is then cooled and steam is diffused into the pores of the bio-char. The steam-laden bio-char is immersed in a liquid bath containing soluble agents that are to be deposited in the pores of the bio-char. The liquid bath cools the char to below the condensation temperature of the steam, whereupon the condensing steam generates a partial vacuum within the pores, drawing the liquid into the pores. The bio-char is then removed from the liquid bath and dried so that the liquid within the pores evaporates, leaving behind the soluble agent. Accordingly, the invention yields bio-char that has soluble agent embedded relatively deep within its pores. | 07-01-2010 |

| 20100060173 | Wireless lighting system for staircases and passageways - The invention discloses an illumination system having a first proximate detector with a first zone detector, which is capable of detecting the passing of a human body. Also part of the proximate detector is a first transmitter that is capable of sending a signal upon the activation of the first zone detector. The invention also has a first staircase illuminator capable of illuminating a first staircase area. Once the first zone detector is activated, the first transmitter sends a signal to a receiver on a second staircase illuminator, which is capable of illuminating a second staircase area. A second zone detector is included that is capable of detecting the passing of a human body, which also causes a second transmitter to send a signal to a receiver on the first staircase illuminator or any other staircase illuminator that is part of the illumination system. Included also is the second staircase illuminator that is capable of illuminating the second staircase area. Therefore, briefly, when a person passes near the first proximate detector, the first zone detector is activated and a signal is sent from the first transmitter to the receiver, causing the receiver to direct the second staircase illuminator to illuminate the second staircase area, while the first staircase area is being illuminated by the first staircase illuminator. By the same token, when a person passes near the second proximate detector, the second zone detector is activates and a signal is sent from the second transmitter to the receiver on a third staircase illuminator, which triggers an illumination of a third staircase area, or back to the receiver on the first staircase illuminator. The process of transmitting, receiving and illuminating may continue for as long as there are devices within the illumination system that have not yet been illuminated. | 03-11-2010 |

| 20100238981 | INTERFERENCE CANCELLATION IN VARIABLE CODELENGTH SYSTEMS FOR MULTI-ACESS COMMUNICATION - A receiver employs low-rate processing to synthesize the effect of high-rate interference in a received multi-rate signal.
