Patent number: 8298323Abstract: The present invention provides a system and method for transmitting information between a device within a housing to a second device, preferably a test or monitoring unit, outside of the housing. There are numerous issues associated with transferring information from within a sealed housing to an external device. In some cases, the use of wires inside the housing may be impractical, due to internal conditions, such as fluid flow, pressure or temperature. In one embodiment, the antenna of the external RF reading device is electrically connected to the dome of the housing. In another embodiment, the device within the housing is electrically connected to a housing component. In another embodiment, the gasket is used to pass information from within the housing to an external device.Type: GrantFiled: January 3, 2012Date of Patent: October 30, 2012Assignee: EMD Millipore CorporationInventors: Michael T. Grzonka, Michael Joens, Aaron Burke

Patent number: 8152912Abstract: A method for determining the charge state of a particle filter installed in the exhaust gas line of an internal combustion engine comprises the following steps: determining the exhaust gas volumetric flow in the flow direction of the exhaust gas downstream of the particle filter (2), detecting the pressure present in the exhaust gas line (1) in the direction of flow of the exhaust gas prior to the particle filter (2), comparing the exhaust gas volumetric flow determined hinter the particle filter (2) with the detected pressure present upstream of the particle filter (2) and evaluating the results of the comparison with consideration to the exhaust gas back pressure of the uncharged particle filter (2) and the exhaust gas back pressure caused by the particle filter charge, said pressure being higher than the uncharged filter. Further described is a corresponding device for reducing the particle emissions of an internal combustion engine.Type: GrantFiled: March 6, 2009Date of Patent: April 10, 2012Assignee: HJS Emission Technology GmbH & Co.

Patent number: 8128728Abstract: A system and process for gas homogenization is disclosed. This has application in the areas of generation of gas and its conversion to electricity in downstream applications. The homogenization system minimizes variance in the gas characteristics (composition, flow, pressure, temperature), thereby rendering a steady stream of gas of consistent quality to the downstream machinery. This homogenization system can be adjusted to optimize the output gas stream for specific end-applications, or to optimize the output gas stream for different input feedstocks. This ensures that overall conversion efficiencies are maximized while keeping the process cost-effective. Such a uniform, steady output gas stream has a wide range of applications in the broad areas of generation of electricity (e.g. using internal combustion engines and combustion turbine engines), chemical synthesis (e.g.Type: GrantFiled: May 7, 2007Date of Patent: March 6, 2012Assignee: Plasco Energy Group, Inc.Inventors: Andreas Tsangaris, Margaret Swain
