20100162213 | SYSTEM AND METHOD FOR MESSAGE CHOREOGRAPHIES OF SERVICES - In one embodiment the present invention includes a computer-implemented method of evaluating interactions between processes. The method includes storing a message choreography meta-model that includes an interaction meta class and a constraint meta-class. The interaction meta-class relates to an exchange of a message between a sender and a receiver, and the constraint meta-class relates to an input to the interaction meta-class. The method further includes executing a user interface computer program with which a user creates a message choreography model between a first process and a second process. The message choreography model is based on the message choreography meta-model. The message choreography model includes interactions that conform to the interaction meta class, and includes constraints that conform to the constraint meta class. The method further includes executing a verification computer program that performs a verification of the message choreography model. The verification includes verifying absence of an inconsumable message. The method further includes executing a testing computer program that performs a testing based on the message choreography model. The testing validates on an existing implementation the message exchange execution described by the choreography. | 06-24-2010 |

20120003814 | Methods For In-Situ Passivation Of Silicon-On-Insulator Wafers - Methods and systems are disclosed for performing a passivation process on a silicon-on-insulator wafer in a chamber in which the wafer is cleaved. A bonded wafer pair is cleaved within the chamber to form the silicon-on-insulator (SOI) wafer. A cleaved surface of the SOI wafer is then passivated in-situ by exposing the cleaved surface to a passivating substance. This exposure to a passivating substance results in the formation of a thin layer of oxide on the cleaved surface. The silicon-on-insulator wafer is then removed from the chamber. In other embodiments, the silicon-on-insulator wafer is first transferred to an adjoining chamber where the wafer is then passivated. The wafer is transferred to the adjoining chamber without exposing the wafer to the atmosphere outside the chambers. | 01-05-2012 |

20110133055 | MICROSTRUCTURE PHOTOMULTIPLIER ASSEMBLY - The subject invention provides for a novel photomultiplier assembly, termed the Microstructure Photomultiplier Assembly (MPA), which enables the effective conversion of light signals (received at the front of the assembly) into readily-detectable electrical signals. The MPA comprises a photocathode (which converts light into electrons and which is located in front of or on the front surface of the assembly), followed by an electron-multiplying plate, or series of plates, each made from an insulating substrate which does not emit sufficient contaminants to poison the photocathode. Each plate is coated on the front and rear faces with a conductive layer. In addition, the front face of each plate is further coated with a layer of secondary electron-emissive material which, when struck by an incoming electron, can produce secondary electrons. Each plate is perforated with channels (with non-conducting walls) and the number and geometry of these channels is designed to promote the efficient transfer and acceleration of electrons through the channel, under an applied voltage differential across the plate(s). The number of plates placed in series is determined by the desired degree of electron multiplication. At the exit of the last plate, an anode is located to collect the electrons and generate an electrical signal that can be read by conventional electronics. The anode can be a simple anode or can be a position-sensitive anode. The spacing between the photocathode, the electron-multiplying plates, and the anode is selected to promote the efficient transfer and acceleration of electrons across the assembly, as well as to promote the efficient production of secondary electrons. The photocathode, electron-multiplying plate(s) and anode are all contained within a vacuum enclosure. | 06-09-2011 |

20090052903 | System and method for expanding PCIe compliant signals over a fiber optic medium with no latency - A system for expanding PCI Express (PCIe) compliant signals over a fiber optic medium with no latency. A standardized fiber optic transceiver is adapted to provide an optimal PCIe expansion over a fiber optic medium. Signal buffers are utilized to translate and fine-tune standardized PCIe traffic to a level of low voltage differential signaling (LVDS) that is comprehensible to a wide range of fiber optic transceivers over a wide range of interface bandwidths. The intended use for such a high-speed LVDS buffer is to strengthen and enable PCIe signals over metal (copper) cable or metal printed circuit board (PCB) traces for large PCBs, such as backplanes, server motherboards, etc. By disposing the PCIe buffer used for metal (copper) cable between the PCIe bus and the fiber optic transceiver, one can achieve the signal conditioning and translating required to allow PCIe signals to pass over the fiber optic medium. | 02-26-2009 |
