    Abstract: A method and a vector network analyzer compensate for unequal source match and load match of a test port of the vector network analyzer. The method characterizes the source match and the load match, computes a delta-match factor from the characterized source match and load match, and uses the delta-match factor to compensate for the difference. The method compensates S-parameter data for a device under test measured by the vector network analyzer. The vector network analyzer comprises a computer program that, when executed by a controller, implements a calibration compensation.

    Abstract: The invention relates to the removal of electronic noise from mass spectra which are scanned as single spectra and added together to give a sum spectrum. The invention consists in removing the noise in the single spectra and not in the sum spectrum since ion signals and electronic noise can only be distinguished in the single spectra.

    Abstract: A method and system are disclosed for automatically generating embroidery designs from a scanned image. An embroidery data generating mechanism generates accurate embroidery designs. The embroidery data generating mechanism first reads an image data file, which contains bitmapping information generated from a software scanning tool, the information being related to an embroidery pattern that has been scanned. The scanned pattern is broken up into pixels, each pixel in the scanned image having a bitmap associated with the color of the pattern. Each unique color in the scanned pattern has its own unique bitmap. The embroidery generating mechanism also includes a segmentation mechanism and a chain-encoding mechanism which perform operations to enhance the quality of the bitmapped information and to separate regions of the scanned image into objects. A distance transform evaluation mechanism classifies each object as being either a thick object or a thin, predominantly regular object. Additional mechanisms further interpret the objects into entities such as regular and singular regions and compute optimum sewing paths for embroidery data generation.

    Abstract: A legged mobile robot is adaptively controlled in its attitude against variable external forces to continue the operation without inversion. When the legged mobile robot kicks an object having a certain mass, such as a ball, the robot is to be prevented from being fallen down by the reactive force from the object. Even if the mass or the repulsion coefficient of the object kicked is unknown, the operation of kicking the object at a sufficiently low speed is carried out at the outset to predict the reactive force produced on actual kicking in order to predict the reactive force produced on actual kicking. The result is that the stability in attitude can be maintained on kicking at an arbitrary speed. The legged mobile robot is able to take part as one of the players in athletic games, such as soccer games, in which each player performs his or her role as the or she is subjected to an external force.

    Abstract: In a wire cut electric discharge machine, a correction block is inserted into a corner of a movement path where the wire electrode is moved by the electrode moving device. The correction block does not correspond to the contour of the workpiece to be machined. When it is necessary to change machining condition such as the voltage to be applied to the wire electrode before and after the corner, a changing position to change the machining condition is set on the correction block.
