20090183630 | APPARATUS AND METHOD FOR REDUCING PARTICLE CONTAMINATION IN A VACUUM CHAMBER - An apparatus and method for maintaining low gas velocity variation across a diffuser membrane during the vent-up of a vacuum chamber is disclosed. The diffuser membrane permeability and the pressure conditions across the membrane are chosen to minimize variation in gas flow velocity through the membrane during the vent-up cycle. This reduces re-distribution of particles from a vacuum chamber onto sensitive substrates in the vacuum chamber during vent-up from sub-atmospheric pressure to atmospheric pressure. | 07-23-2009 |
20090282979 | LOW-PROFILE SURFACE MOUNT FILTER - Embodiments of the present invention provide low-profile surface mount filters. One embodiment of the present invention includes a filter housing adapted to mount on a substrate block having a plurality of flow paths and a filter cavity defined therein. The filter cavity is defined to extend in a generally horizontal direction when the low-profile filter is in use. A first flow passage is defined to connect an inlet of the filter housing to a first section of the filter cavity and a second flow passage is defined to connect a second section of the filter cavity to an outlet of the filter housing. A filter assembly is disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and second section of the filter cavity. | 11-19-2009 |

20140324323 | AUTOMOTIVE COMBINATION SENSOR - Systems are provided for EGR mass and air mass estimation during steady state and transient operations. By utilizing a combination sensor comprising of a manifold absolute pressure sensing element and a differential pressure sensing element sharing a common pressure chamber with connections to the intake manifold, errors in EGR mass estimation may be reduced. | 10-30-2014 |
20150226108 | DUAL INLET AND OUTLET EXHAUST GAS RECIRCULATION COOLER FOR TURBOCHARGED ENGINE - Methods and systems are provided for a high-pressure exhaust gas recirculation (EGR) system of a parallel twin-turbocharged internal combustion engine. Using an EGR cooler with a single exhaust inlet and outlet to cool recirculated exhaust gas may increase the complexity and size of the engine package, along with adding unnecessary cost from extra ductwork to decrease the chance of turbocharger boost imbalance. To provide a way to reduce package size without affecting engine performance, an EGR cooler with two exhaust inlets and outlets is used to cool exhaust flows leading from two cylinder banks. | 08-13-2015 |
