    Abstract: A method may include forming a mask layer on top of a first dielectric layer formed on a first source/drain and a second source/drain, and creating an opening in the mask layer and the first dielectric layer that exposes portions of the first source/drain and the second source/drain. The method may include filling the opening with a metal layer that covers the exposed portions of the first source/drain and the second source/drain, and forming a gap in the metal layer to create a first metal contact and a second metal contact. The first metal contact may electrically couple to the first source/drain and the second metal contact may electrically couple to the second source/drain. The gap may separate the first metal contact from the second metal contact by less than nineteen nanometers.

  • Publication number: 20200327403
    Abstract: An all-optical neural network that utilizes light beams and optical components to implement layers of the neural network is disclosed herein. The all-optical neural network includes an input layer, zero or more hidden layers, and an output layer. Each layer of the neural network is configured to simulate linear and nonlinear operations of a conventional artificial neural network neuron on an optical signal. In an embodiment, the optical linear operation is performed by a spatial light modulator and an optical lens. The optical lens performs a Fourier transformation on the set of light beams and sums light beams with similar propagation orientations. The optical nonlinear operation is implemented utilizing a nonlinear optical medium having an electromagnetically induced transparency characteristic whose transmission of a probe beam of light is controlled by the intermediate output of a coupling beam of light from the optical linear operation.

  • Patent number: 10164873
    Abstract: Systems and methods utilize an all-or-none switchover to prevent split-brain problems in a Multi-Chassis Link Aggregation Group (MC-LAG) network. A standby node in the MC-LAG network can perform the steps of remaining in a standby state responsive to a loss of adjacency with an active node, wherein, in the standby state, all standby links between the standby node and a common endpoint are non-distributing; monitoring frames transmitted by the common endpoint to the standby node over the standby links; and determining based on the monitoring frames whether all active links between the active node and the common endpoint have failed and entering an active state with all the standby links distributing based thereon.

    Abstract: An air-fuel parameter control system includes an injector, an air-fuel parameter sensor, a fuel film parameter calculation module, an air-fuel parameter prediction module and a fuel injection calibration module. The injector injects fuel into an intake manifold. The air-fuel parameter sensor detects a detected air-fuel parameter in an exhaust pipe. The fuel film parameter calculation module calculates a fuel film parameter relating to a fuel film accumulated the intake manifold based on the detected air-fuel parameter, an amount of the injected fuel and an amount of air flowing into the engine. The air-fuel parameter prediction module predicts a predicted air-fuel parameter based on the detected air-fuel parameter and the fuel film parameter. The fuel injection calibration module calibrates the amount of the injected fuel based on a difference between a reference air-fuel parameter and the predicted air-fuel parameter.

  • Patent number: 8904820
    Abstract: A wearable dining utensil comprises a rigid function portion for engaging food, a holder for holding the dining utensil, a shapeable connector having a third linking part and a fourth linking part for fixing a bendable portion, and a fifth linking part having an outlet for linking with the fourth linking part. One end of the rigid function portion also serves as a male linker and the opposite end has a first linking part. One end of the holder serves as a female linker for linking with the male linker, and the opposite end has a second linking part. When the female linker is linked with the male linker, the dining utensil forms a loop, and when the outlet is linked with the fourth linking part, the dining utensil forms a regular utensil. According to various connecting profiles, the dining utensils can form a bracelet, necklace or an ornament.
