    摘要: The invention provides a phase calibration module, calibrating phase mismatch between microphone signals output by a plurality of microphones of an array microphone. In one embodiment, the phase calibration module comprises a subband filter, a delay calculation module, and a delay compensation filter. The subband filter extracts a high frequency component and a low frequency component from each of the microphone signals to obtain a plurality of high-frequency component signals and a plurality of low-frequency component signals. The delay calculation module calculates delays between the low-frequency component signals. The delay compensation filter then compensates the low-frequency component signals for phase mismatches therebetween according to the calculated delays to obtain a plurality of calibrated low-frequency component signals.

    摘要: A dual-stage switching system for lithographic machine includes a wafer stage to be operated in an exposure station and another wafer stage to be operated in a pre-processing station. The two wafer stages are provided on a base, with four 2-DOF driving units capable of moving along X direction and Y direction being provided along the edge of the base, and the wafer stages being disposed in a space surrounded by the four 2-DOF driving units and suspended on an upper surface of the base by air bearings. Each of the 2-DOF driving units includes upper and lower linear guides and a guiding sleeve, with the upper and lower linear guides being installed vertical to each other in their corresponding guiding sleeve. Two adjacent 2-DOF driving units cooperatively drive the wafer stage) to move in the X direction and Y direction.

    摘要: A magnet arrangement for creating a magnetic field. The magnet arrangement includes a first magnet having a first surface defining a first pole and a second surface defining a second pole opposite the first pole, and a second magnet having a third surface defining a third pole and a fourth surface defining a fourth pole opposite the third pole. The second surface has a higher magnetic flux density than the first surface. The third surface has a higher magnetic flux density than the fourth surface. The second magnet is spaced from the first magnet to define a first gap between the second surface and the third surface. Magnetic field lines of the magnetic field run from the first surface to the second surface, from the second surface to the third surface through the first gap, and from the third surface to the fourth surface.

    摘要: A micro stage with 6 degrees of freedom used in super-precise processing and sensing equipment fields is disclosed. The micro stage has three sets of electromagnetic driving units arranged in a horizontal plane for driving the micro stage to obtain movements within the horizontal plane with 3 degrees of freedom in X, Y and θz directions and three electromagnetic driving units arranged in a vertical direction for driving the micro stage to obtain additional movements with 3 degrees of freedom in Z, θx and θy directions. Direct driving by electromagnetic force is used in the invention. The invention is also applicable in super-precise processing and sensing fields for achieving 6 degree-of-freedom motions. The micro stage, which operates on the basis of Lorentz Law, provides a linear relation between the output pushing force and the input electrical current.

    摘要: Web page load time production and simulation includes determining an original page load time (PLT) of a webpage and timing information of each web object of the web page in a scenario. Each object is also annotated with client delay information based on a parental dependency graph (PDG) of the web page. The time information of each web object is further adjusted to reflect a second scenario that includes one or more modified parameters. The page loading of the web page is then simulated based on the adjusted timing information of each web object and the PDG of the web page to estimate a new PLT of the web page.
