  • Publication number: 20140121010
    Abstract: Computer system to facilitate video gaming comprising a processing unit and a computer readable medium coupled to the processing unit comprising instructions executable by the processing unit. Instructions are for a video game that receives first input events triggered by operation of first input devices used to navigate the video game. Instructions are for input adaptation module to facilitate playing the same video game using the second input device that is free from facility to provide the first input events using the first input devices. The input adaptation module receives second input events triggered by operation of the second input device used to navigate the game. It generates the first input events from the second input events, based at least upon the game-specific translation mapping between input events receivable from the second input device and input events receivable from the first input devices. Associated method is also provided.

  • Publication number: 20110236363
    Abstract: Disclosed herein is a system and method for producing T cells from stem cell populations. Specifically exemplified herein is a culture system and method that produces CD4 cells and/or T cell subtypes from a CD4 lineage using a sample of hematopoietic stem cells. Adult hematopoietic precursor/stem cells (HPC) are progenitors to all lineages of immune cells. There has been limited success in generating functional CD4 T cells with this convenient culture system. Also disclosed herein is a novel stromal cell line expressing DL1, interleukin-7 (IL-7), and FMS-like tyrosine kinase 3 ligand (Flt3-L). This improved culture system can greatly facilitate the study of late T cell development and enables immunotherapeutic applications.

  • Patent number: 7766961
    Abstract: Bifurcated delivery assemblies provide bilateral access to first and second branch lumens extending from a main body space or lumen in a patient. One or more interventional devices are combined with the delivery assemblies for delivery s into one or both of the branch lumens. Bilateral renal stenting or embolic protection procedures are performed using the combination delivery/interventional device assemblies. Fluids may also be injected or aspirated from the assemblies. A bifurcated catheter has a first fluid port located on one bifurcation branch, a second fluid port located on a second branch of the bifurcation, and a third fluid port positioned so as to be located within a vena cava when the first and second ports are positioned bilaterally within first and second renal veins.
