| 20090304094 | Dual Carrier Modulation Soft Demapper - An Orthogonal Frequency Division Multiplexing (OFDM) communication system with a transmitter and a receiver. The transmitter is arranged to transmit channel estimation sequences on each of a plurality of band groups, or bands, and to transmit data on each of the band groups or bands. The receiver is arranged to receive the channel estimation sequences for each band group or band to calculate channel state information from each of the channel estimation sequences transmitted on that band group or band and to form an average channel state information. The receiver receives the transmitted data, transforms the received data into the frequency domain, equalizes the received data using the channel state information, demaps the equalized data to re-construct the received data as soft bits and modifies the soft bits using the averaged channel state information. | 12-10-2009 |

| 20110274666 | METHOD OF ENGRAFTING CELLS FROM SOLID TISSUES - A method of repairing diseased or dysfunctional organs or of establishing a model system of a disease state is provided. For repairing diseased organs, the method involves engraftment of cells from healthy tissue of the diseased or dysfunctional organ admixed with gel-forming biomaterials and nutrient medium, signaling molecules and extracellular matrix components that can be made insoluble rapidly upon transplantation to form a graft. In this way, the graft mimics the complexity of the native microenvironment with a minimum number of components that allow transplantation of cells to successfully engraft, expand and then rebuild part or the entirety of the diseased or dysfunctional organ. In the case of using grafting methods for establishing a disease model, diseased cells may be transplanted in the biomaterials and into experimental hosts. | 11-10-2011 |
