  • Patent number: 7430167
    Abstract: A method and a system to adapt the load balancing of the incoming traffic over the planes of a parallel packet switch (PPS) on the basis of the monitoring of requests and acknowledgments exchanged between ingress port adapters and arrays of collapsed virtual output queues (cVOQ) situated within the plane switch cores is disclosed. According to the invention, at least one counter is associated, in each ingress port-adapter, to each individual switching plane or device to be monitored. Each of these counters is incremented when a request is sent to the corresponding individual switching plane or device and decremented when an acknowledgment is received from this individual switching plane or device. When the range of values taken by the counters of a same ingress port-adapter reaches a predetermined threshold, less (or none) incoming traffic is further transmitted to the individual switching plane or device associated to the higher value counter. An alarm signal is possibly raised too e.g.

  • Patent number: 7288443
    Abstract: P-type MOSFETs (PMOSFETs) are formed by encapsulating the gate with an insulator and depositing a germanium containing layer outside the sidewalls, then diffusing the germanium into the silicon-on-insulator layer or bulk silicon by annealing or by oxidizing to form graded embedded silicon-germanium source-drain and/or Extension (geSiGe-SDE). For SOI devices, the geSiGe-SDE is allowed to reach the buried insulator to maximize the stress in the channel of SOI devices, which is beneficial for ultra-thin SOI devices. Graded germanium profiles provide a method to optimize stress in order to enhance device performance. The geSiGe-SDE creates a compressive stress in the horizontal direction (parallel to the gate dielectric surface) and tensile stress in the vertical direction (normal to the gate dielectric surface) in the channel of the PMOSFET, therebyforming a structure that enhances PMOSFET performance.

  • Patent number: 7265019
    Abstract: A micro electro-mechanical system (MEMS) variable capacitor is described, wherein movable comb electrodes of opposing polarity are fabricated simultaneously on the same substrate and are independently actuated. The electrodes are formed in an interdigitated fashion to maximize capacitance. The MEMS variable capacitor includes CMOS manufacturing steps in combination with elastomeric material selectively used in areas under greatest stress to ensure that the varactor will not fail as a result of stresses that may result in the separation of dielectric material from the conductive elements. The combination of a CMOS process with the conducting elastomeric material between vias increases the overall sidewall area, which provides increased capacitance density.

  • Patent number: 7180966
    Abstract: A transition detection, validation and memorization (TDVM) circuit detects the position of a transition in a stream of serially transmitted binary data (bits) that are over sampled and generates a control signal indicating which sampled signal represents the best data. The incoming data stream is over sampled by the n phases of a multiple phase clock signal. Then n over sampled signals are fed into the TDVM circuit which includes a first section for detecting the transition at the positions of two consecutive sampled signals according to a specific signal processing, a second section for validating the transition position, and a third section for memorizing the validated transition position and generating a control signal that is used to recover the data.

  • Patent number: 7173600
    Abstract: To supply selection signals to multiplexed pixels efficiently. For a period from time t0 to time t2, first, during a period from time t0 to time t1, a pixel electrode A11 is driven by selecting scan lines Gn+1 and Gn+2, and next, during a period from time t1 to time t2, a pixel electrode B11 is driven by selecting only the scan line Gn+1. Moreover, during the period from time t1 to time t2, scan lines Gn+3 and Gn+4 are also selected, and thus a pixel electrode A12 is driven. After time t2, at least one of the scan lines Gn+3 and Gn+4 is not selected before the pixel electrode A12 is driven by selecting both of the scan lines Gn+3 and Gn+4 during a period from time t4 to time t5. Accordingly, the pixel electrode A12 can be preliminarily charged during the period from time t1 to time t2 and can maintain a potential preliminarily applied thereto until the pixel electrode A12 is driven during the period from time t4 to time t5.
