Abstract: A system for performing the method of this invention includes a leader having a robot arm able to articulate about first axes and supporting an end effector. A follower includes a robot arm able to articulate about respective second axes. Servo motors articulate the leader arm about the first axes and the follower arm about the second axes. A user interface allows a user to jog the arm of the leader and to program movement of the arms for automatic execution such that the end effector reaches predetermined positions. A controller, operatively connected to the servo motors and the user interface, controls operation of the servo motors, moves the arm of the leader in accordance with the programmed movement, and moves the arm of the follower such that it tracks or mirrors movement of the leader.

Abstract: A golf club head includes a body, an upper cap and a support plate. The body is hollow, having an opening in an upper wall, and the opening has an annular combining surface. The upper cap is positioned on the body and closes up the opening. The support plate is positioned in the body, having two recessed end surfaces to fit with the inner edge of the opening, with one recessed end surface located near a striking face of the body to prop up sidewise the striking face so that the striking face may have strength enough to endure shocks at the moment of striking a ball. The support plate has an intermediate curved portion flush with the top of the annular combining surface. The upper cap is adhered with the annular combining surface and the curved portion of the support plate. Then the club head is reinforced in its combined strength to prevent it from disfiguring and to lessen its cost.

Abstract: The present invention generally relates to encoding/decoding method and device used for remote controller, which utilizes baud rate to encrypt data for transmission. The encoding device of the present invention comprises an encoder for encoding an identification code into an encrypted code; an interpreter for interpreting the un-encoded portion of the identification code and the encrypted code into a transmission signal. Wherein, when the encrypted code is in a first base, the plain code corresponding to the encrypted code will be transmitted with a first baud rate; and when the encrypted code is in a second base, the plain code corresponding to the encrypted code will be transmitted with a second baud rate.

Abstract: The invention is a power-saving method for driving light-emitting diode, and the device employing the method is a matrix display screen that comprises a driving circuit, a memory, and a light-emitting diode. When the display screen performs scanning process, one of the output data and the internal data of the memory is checked. If the data being checked is zero, the execution of scanning a predetermined row of the screen is postponed for one period so that no action is taken. Postponing will achieve a power-saving function for the display screen comprising the light-emitting diode.

Abstract: A servo spot welding control system and method to efficiently weld a pair of workpieces together. The system includes a robot movable about the workpieces, a weld gun, servomotors, a transformer, and a controller. The weld gun is mounted on the robot and includes at least two pairs of electrodes.

Abstract: A method of determining position information of a workpiece relative to a robot includes the ability to move the workpiece into a variety of orientations relative to the robot during the touch sensing location procedure. The position information is then used for performing a robot operation including coordinated motion. A coordinated reference frame is defined with respect to a moveable positioner that supports the workpiece. Known kinematic relationships between the positioner and the robot are used to control operation of the robot within the coordinated reference frame throughout the touch sensing location procedure. By moving the workpiece relative to the robot during the touch sensing location procedure, a greater variety of workpieces can be processed and relatively complicated workpiece configurations can be accurately determined. The robot operating parameters are modified according to the determined position information.

Abstract: A carrier plate for forming a plug contact of an electrical connector assembly includes a plurality of contacts (1) and carriers (2, 3) connecting the contacts together. Each contact forms a body (11) and several tails (12) extending from the body. Each body comprises an upper portion (13) and a lower portion (14) having the same shape. A hole (16; 16′) is disposed in the upper and lower portions proximate the tails for guiding the carrier plate during a bending process and for inspecting the qualty of the contact after the bending process is complete. The carriers connect the tails together for facilitating manufacture of the contacts and reducing costs.

Abstract: A method of controlling movement of a robot includes moving only the wrist portion about two of the wrist axes to achieve a repeated and cyclical movement, such as a back-and-forth movement of the tool relative to a preselected path. Since only the wrist is moved, the range of available tool positions can be determined. In most instances, the desired position of the tool as it deviates from the path is outside of the range of available tool positions, given that only the wrist will move. The method of this invention includes determining a target position within the range of available positions that best corresponds to the desired position of the tool. A unique inverse kinematics solution, which includes fixing one of the wrist axes, is used to determine the wrist orientation required to place the tool into the target position.
