摘要： The present invention discloses a method for measuring a mode field diameter (MFD) of a single-mode fiber using an optical integration technique employing a gradually variable aperture. The method transforms, according to Petermann II definition, an integral operation in a formula of an MFD of a single-mode fiber into elementary arithmetic operations to be performed on a mean square value of the numerical aperture of the fiber. By using an optical integrator having a gradually variable aperture, the mean square value of the numerical aperture of the single-mode fiber can be precisely measured by one of the following three methods: translation, rotation and beam splitting, thus accordingly solving the MFD of the test fiber. The aforementioned measurement an MFD of a single-mode fiber is characterized by precision, high speed and convenience, and can be widely applied in various applications, such as measurement standards, automated test equipment, and engineering instruments.

摘要： A method and apparatus for rounding a sharp edge of a model of an object is disclosed whereby a ball is propagated in a desired direction along the edge to be smoothed. The position of the ball at each point in its propagation is noted and, as a result, a virtual tunnel through which the ball passed may be constructed. Points on the sides of the surface of the object in proximity to the sharp edge are then projected onto the virtual tunnel by connecting with a line each point in proximity to the sharp edge to the center of the tunnel. New projected points are created at each position on the surface of the tunnel where the lines intersect that surface. The original points along the sharp edge are then hidden or deleted and the points along the virtual tunnel are connected via well-known surface reconstruction methods. In this way, a sharp edge of a triangle mesh model are advantageously smoothed.

摘要： A travel information server estimates travel demand with mobility data. The server identifies activity types of users based, at least in part, on mobility data of the users. The mobility data has been collected over time and indicates at least locations and corresponding times at the locations. Travel information is generated with the mobility data for each of the activity types. The travel information for a first of the activity types is adjusted based, at least in part, on travel-related event data that corresponds to the first activity type to generate an adjusted travel information for the first activity type. The travel-related event data indicates an event that potentially influences travel for a short term computing an estimated travel demand with a combination of the adjusted travel information for the first activity type and the travel information for at least a second of the activity types.

摘要： Self-interference cancellers are provided. The self-interference cancellers can include multiple second-order, N-path Gm-C filters. Each filter can be configured to cancel self-interference on a channel of a desired bandwidth. Each filter can be independently controlled using a variable transmitter resistance, a variable receiver resistance, a variable baseband capacitance, a variable transconductance, and a variable time shift between local oscillators that control switches in the filter. By controlling these variables, magnitude, phase, slope of magnitude, and slope of phase of the cancellers frequency responses can be controlled for self-interference cancellation. A calibration process is also provided for configuring the canceller.
