20100217392 | REINFORCED PTFE MEDICAL BARRIERS - Systems, methods and devices usable in the repair of a bone defect are described. A portion of a bone defect is covered with a multilayered membrane that includes a reinforcing layer. A member of the reinforcing member is fastened to an area of bone and soft tissue is secured about the membrane. The membrane facilitates healing of the defect. One membrane comprises a plurality of layers that includes a binding layer and a PTFE layer which has a textured surface and a substantially smooth surface. The textured surface provides a top surface of the membrane and the substantially smooth surface contacts bone. | 08-26-2010 |
20110060420 | PTFE COMPOSITE MULTI-LAYER MATERIAL - A composite multi-layer material may generally comprise a d-PTFE material combined with an open structured material (either resorbable or non-resorbable) creating a composite multi-layer material. Attachment of the layers may be accomplished by stitching layers of material, exertion of hydraulic or other pressure, application of a biocompatible adhesive or heat, or some combination of the foregoing. Use of a d-PTFE, unexpanded material has multiple alternative uses, including without limitation, placement on the visceral side of a hernia that may minimize or even eliminate the incidence of abdominal adhesions. Alternatively, the material may be used to create tubing sufficient as a graft for treating abdominal aortic aneurysms. | 03-10-2011 |

20140111349 | METHODS AND APPARATUS FOR EVALUATING DOWNHOLE CONDITIONS WITH RFID MEMS SENSORS - A radio frequency identification (RFID) tag can include a die attached to an inductive-capacitive (LC) circuit including a capacitive element coupled to an inductive element. The LC circuit can have a resonant frequency that varies according to properties of fluid proximate the RFID tag. The RFID tag can further include a coating material disposed around the die to form an outer surface of the RFID tag. The coating material may have a thickness over a portion of the LC circuit, to permit a conductivity property of a fluid proximate the outer surface to affect the resonant frequency of the LC circuit such that the resonant frequency shifts to a second resonant frequency. Additional apparatus, systems, and methods are disclosed. | 04-24-2014 |

20140354443 | METHODS AND SYSTEMS FOR DETECTING RFID TAGS IN A BOREHOLE ENVIRONMENT - Sensor assemblies are deployed in a borehole for a well, such as an oil well or other hydrocarbon recovery well. The sensor assemblies may be coupled to a casing string (e.g., the exterior of the casing), and detect RFID tags or other properties of material (e.g., fluids) in an annulus surrounding the casing string. During cementing or other operations, RFID tags may be used to track fluids. RFID detection circuits may be used to scan at different frequencies, and corresponding results may be compared by various means and processes to determine the presence of RFID tags. | 12-04-2014 |

20110269114 | YEAST GROWTH MAXIMIZATION WITH FEEDBACK FOR OPTIMAL CONTROL OF FILLED BATCH FERMENTATION IN A BIOFUEL MANUFACTURING FACILITY - The present invention provides novel techniques for controlling biofuel production processes. In particular, estimated yeast activity values are determined by yeast activity sensors. These estimated yeast activity values are used to bias predicted yeast activity values from an inferential dynamic predictive model. The biased predicted yeast activity values are in turn used to control a fermentation sub-process of the biofuel production process, while also be used to update the inferential dynamic predictive model, to maximize yeast activity in the fermentation sub-process. Maximizing yeast activity and yeast growth in the fermentation sub-process leads to the maximization of biofuel production in the biofuel production process. | 11-03-2011 |
20120003623 | NONLINEAR MODEL PREDICTIVE CONTROL OF A BATCH REACTION SYSTEM - The present invention provides novel techniques for controlling batch reaction processes. In particular, a parametric hybrid model may be used to parameterize inputs and outputs of batch reaction processes. The parametric hybrid model may include an empirical model, a parameter model, and a dynamic model. Critical quality parameters, which are correlated with, but not the same as, end-of-batch quality values for the batch reaction processes may be monitored during cycles of the batch reaction processes. The quality parameters may be used to generate desired batch trajectories, which may be used to control the batch reaction processes during the cycles of the batch reaction processes. | 01-05-2012 |
