Abstract:
A method for controlling rate matching in a communications system includes calculating a rate matching parameter containing a basic variable for an input bit string, and evaluating an additional parameter reflecting a current channel status of the transport channel receiving the input bit string. The input bit string generated in the upper layer is mapped to a physical channel of a Physical Layer by performing bit repeating or bit puncturing. If the bit repeating is executed on the input bit string on the basis of the first basic variable, and a second basic variable is calculated using the first basic variable and the additional parameter. A communication device to control rate matching between a physical channel and a transport channel includes a parameter calculator, an additional parameter generator, and a rate matching executioner to execute bit repeating or bit puncturing.

Provided is a wiper driving apparatus for an automobile. The wiper driving apparatus includes: a housing; a driving motor; a worm wheel installed in the housing to be rotated by the driving motor, connected to a wiper arm, and having protrusions formed on a surface thereof; and a clutch member eccentric with respect to the center of the worm wheel to be rotatably installed in the housing such that power supply to the driving motor is selectively turned on or off according to the position of the rotating clutch member relative to the housing, wherein the clutch member has an engagement unit which is caught by the protrusions of the worm wheel when the worm wheel is rotated in a first direction, and is not caught by the protrusions of the worm wheel when the worm wheel is rotated in a second direction. Accordingly, the wiper driving apparatus enables the clutch member to be disposed within the radius of rotation of protrusions without deviating from its normal track although the protrusions are rotated in a reverse direction.

Abstract:
A method for detecting an initial welding point of a welding robot regardless of any irregularity of a parent metal to be welded and the displacement thereof caused by fastening the parent metal. The method includes identifying a first directional vector oriented toward a virtual point given at a weld end part of a roughly taught welding start point and, identifying a second directional vector indicating a direction of a torch which is oriented toward a weld part and bisects an angle included between welding surfaces of the parent metal. Horizontal and vertical tracking directions are coincided with the direction of the second directional vector are determined when the second vector rotates in a positive(+) and negative(-) direction about the first directional vector, respectively. The torch is moved in the determined horizontal and vertical tracking directions until weld deposition occurs, and after weld deposition, the torch is moved to the determined positions on the basis of operation parameters. The torch is then moved in a direction opposite to a welding proceeding direction on the basis of the determined operation parameters and tracking the end of the parent metal. If the weld deposition occurs at an end of the parent metal, the torch is moved in the welding proceeding direction to return the torch to the initial welding point.
