| 20090190791 | Acoustic transducer comprising a plurality of coaxially arranged diaphragms - An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage. | 07-30-2009 |

| 20100278145 | Label Switched Packet Transfer Device - A device for connecting base station(s) to a cellular label switched network in a cellular network. The cellular network includes: base station(s), the connecting device(s); cellular label switched network(s); and service area(s). The base station(s) communicates with mobile terminals using wireless technology. The wireless technology uses a protocol layer architecture that includes at least one of the following: a wireless physical layer; a wireless medium access control protocol layer; a radio link control layer; and a network layer. The connecting device(s) include: a first interface to connect to the base station(s); a second interface to connect to cellular label switched network(s); and a label forwarding layer that: forwards packets between base station(s) and cellular label switched network(s); attaches label(s) to packets and removes label(s) from packets. A service area divided into a multitude of cells through which mobile terminals can move through and communicate with base station(s). | 11-04-2010 |

| 20090074980 | Method and apparatus to color vinyl slats - A method and apparatus for coloring slats utilizes a roller, such as an Anilox roller, and enclosed doctor blade subassembly for metering an amount of colorant transferred to the object, and a felt-wiper subassembly for removing colorant from a roller, such as a discharge roller. The doctor blade subassembly includes a pair of side plates located at opposing ends of a doctor blade to enclose a portion of the roller and prevent colorant from building up on a side of the roller while the colorant is being applied to the roller and as excess colorant is being scraped off by the doctor blade. The felt-wiper subassembly includes a wiper blade and a felt insert that combine effectively to remove colorant that is deposited on a roller, such as a discharge roller, that contacts the object once the colorant has been transferred to the object. | 03-19-2009 |

| 20090110732 | BIORESORBABLE COMPOSITION FOR REPAIRING SKELETAL TISSUE - Bioresorbable compositions for treating skeletal tissue are disclosed. The biomedical compositions are formed from a polylactide polymer, a polyglycolide polymer, or a poly(lactic-co-glycolic acid) polymer having a relatively low molecular weight. For instance, the average number molecular weight of the polymer is generally less than 10,000, such as from about 500 to about 5,000. Fumarate groups are incorporated into the low molecular weight polymer that provide crosslinking sites. If desired, ethylene oxide groups and ceramic particles may also be incorporated into the polymer for producing compositions having a variety of properties. For example, the biomedical composition of the present disclosure can be used to treat soft skeletal tissue or to treat hard skeletal tissue. The biomedical compositions are biodegradable and can contain various therapeutic, beneficial and pharmaceutical agents that may be released during degradation of the polymer. | 04-30-2009 |
