| 20090028733 | Compressor Valve Plate Assembly with Integrated Gasket - A valve plate assembly is provided including a plastic plate having a plurality of apertures therethrough, including at least one suction passage and at least one exhaust passage. A suction reed valve is disposed over the suction passage and an exhaust reed valve is disposed over the exhaust passage. A cylinder gasket is molded to a first side of the plastic plate and is adapted to seal around a cylinder of a cylinder housing. The cylinder gasket is recessed in a groove in the plastic plate. An end cap gasket is molded to a second side of the plastic plate and is adapted to seal against an end cap of a compressor. The end cap gasket is recessed in a groove in a second side of the plastic plate. The reed valves contact the plastic plate and are, therefore, quieter than a reed valve that is operated against a metal plate. The integration of the gasket into the recessed grooves of the plastic valve plate eliminates potential leak paths that exist with current designs. The use of a plastic valve plate also greatly reduces the weight and cost of the valve plate assembly. The valve plate assembly also provides an assembly which can be shipped to a customer in one piece for easier handling and installation. | 01-29-2009 |
| 20090050462 | INTEGRATED CONDUCTIVE RADIO BUTTON - An integrated conductive button, includes a housing and a printed circuit board mounted in proximity to the housing. The printed circuit board includes at least one electric contact portion disposed thereon and a button member is supported by the housing and includes at least one elongated post having a conductive elastomeric material disposed on a tip of the at least one elongated post. An elastomeric web skirt surrounds the at least one elongated post and is disposed against a seat surface of the housing. Upon pressing the button member, the elastomeric web skirt buckles to allow the conductive elastomeric material on the tip of the elongated post to contact the at least one electric contact on the printed circuit board. | 02-26-2009 |

| 20120027026 | SCALABLE INTERCONNECT MODULES WITH FLEXIBLE CHANNEL BONDING - The present application discloses apparatus and methods for increasing channel utilization for a high-speed serial interface of an integrated circuit (IC). A new circuit architecture is disclosed which provides circuitry that may be programmed flexibly to support a multitude of different channel bonding schemes. In accordance with one aspect of the invention, the new architecture decouples the granularity of control-signal channel bonding from the granularity of data-aggregation channel bonding. This advantageously allows optimization of configurations for both types of channel bonding. In another aspect of the invention, the logical boundaries of bonded user channels are decoupled from the physical boundaries of the PCS modules. This decoupling advantageously eliminates a rigid constraint of previous architectures. | 02-02-2012 |
