Abstract: Disclosed is a mat, method, and program for measuring a golf posture that are capable of measuring a golf club swing speed. The golf posture measuring mat capable includes a sensor unit sensing a pressure corresponding to a golf posture of a user and a trajectory of a head of a golf club, a control unit analyzing the golf posture of the user and a swing speed of the golf club based on a sensed signal of the sensor unit, a display unit displaying analysis data analyzed by the control unit, and a storage unit storing the analysis data and reference data. A plurality of sensors in the sensor unit are arranged one-dimensionally or two-dimensionally on a mat plate. Each of the plurality of sensors includes a single sensor including one among a capacitive pressure sensor, a resistive pressure sensor, and a hybrid pressure sensor, or includes a composite sensor including two or more among the capacitive pressure sensor, the resistive pressure sensor, and the hybrid pressure sensor.

Abstract: Disclosed herein are a method for welding electrode taps of a secondary battery which improves insulation defects generated during welding between the electrode taps and lead parts and an electrode assembly manufactured thereby. The method for welding electrode taps includes performing main welding to connect electrode taps protruded from electrode plates provided in a battery and lead parts electrically connecting the electrode taps to external terminals and having a lead film on the surfaces thereof and, in main welding, a welding part is formed in a partial section of an overlapping region between the electrode tap and the lead part, and a non-welding section is formed between the welding part and the lead film.
