| 20110223644 | Device for fuel and chemical production from biomass-sequestered carbon dioxide and method therefor - A process and apparatus for sequestering carbon and converting it to fuel, such as methane, and/or materials, such as fermentation substrates, biopolymers, bioplastics, oils, pigments, biochar, metals, such as mercury, chromium and arsenic, fibers, proteins, vitamins, fertilizers and animal feed. The apparatus comprises a deep well carbon-sequestering bioreactor coaxially located within a deep well anaerobic bioreactor. Carbon is sequestered into a photosynthetic biomass or a heterotrophic biomass, which is subsequently digested by an anaerobic biomass containing methanogenic microbes, whereby methane is a digestion product. Alternatively, the biomass can be subjected to physical-chemical treatment to produce oil and other useful byproducts. | 09-15-2011 |

| 20080252424 | Stochastic Communication Protocol Method and System For Radio Frequency Identification (Rfid) Tags Based on Coalition Formation, Such as For Tag-To-Tag Communication - Data carriers (such as RFID tags) are formed into clusters of data carriers. Each cluster has at least one bridge data carrier that can communicate with a bridge data carrier of another cluster, thereby allowing data carriers in each cluster to communicate directly or indirectly with each other using a stochastic communication protocol method. Direct tag-to-tag communication capability is provided between data carriers in each cluster and/or between clusters. The data carriers can backscatter and modulate a carrier wave from a source, thereby using the backscattered and modulated carrier wave to convey data to each other. | 10-16-2008 |
| 20090085749 | SYSTEMS AND METHODS FOR WIRELESSLY MARKING MEDIA - A media marking transponder system includes a media fastener and a wireless transponder circuit coupled to the media fastener. The antenna for the wireless transponder circuit has a first effective length when no piece of media is fastened to the media fastener and a second, different effective length when at least one piece of media is fastened to the media fastener. | 04-02-2009 |
| 20090189816 | NEAR-FIELD AND FAR-FIELD ANTENNA-ASSEMBLY AND DEVICES HAVING SAME - Systems, methods, and devices wirelessly communicate in a near-field region and a far-field region. A device may include a near-field antenna and a far-field antenna. The device may be configured to selectively operate in a near-field mode, employing the near-field antenna, and/or in a far-field mode, employing the far-field antenna, and/or in a joint mode, employing both the near-field antenna and the far-field antenna separately or concurrently. One type of device may be a wireless communications data-reader device configured for both near-field and far-field communications. Another type of device may be a wireless communications data-provider device configured for both near-field and far-field communications. | 07-30-2009 |
| 20090231142 | SYSTEM AND METHOD FOR DETERMINING RFID TAG PLACEMENT - In systems and methods for determining the placement of radio-frequency identification (RFID) tags, a tag reader communicates with one or more RFID tags at different locations of a target object. The tag reader determines which of the different locations is a preferable location for placing an RFID tag by detecting the transmission power level or other value required to communicate with the RFID tag at each of the different locations. | 09-17-2009 |
| 20090251288 | METHOD AND APPARATUS FOR RFID TAG DETECTION AND CHARACTERIZATION - This disclosure discloses methods and apparatus for detecting and characterizing radio-frequency identification (RFID) tags. | 10-08-2009 |
