Abstract: A dual release actuator for a vehicle seat includes a motor, a cable carrier configured to receive power of the motor, thereby rotating to selectively pull one of two different cables, a Hall sensor to sense rotation of the motor, and a controller configured to count a sensing pulse of the Hall sensor for controlling rotation of the motor.

Abstract: A method of transmitting a Physical Layer Convergence Procedure (PLCP) frame in a Very High Throughput (VHT) Wireless Local Area Network (WLAN) system includes generating a MAC Protocol Data Unit (MPDU) to be transmitted to a destination station (STA), generating a PLCP Protocol Data Unit (PPDU) by adding a PLCP header, including an L-SIG field containing control information for a legacy STA and a VHT-SIG field containing control information for a VHT STA, to the MPDU, and transmitting the PPDU to the destination STA. A constellation applied to some of Orthogonal Frequency Division Multiplex (OFDM) symbols of the VHT-SIG field is obtained by rotating a constellation applied to an OFDM symbol of the L-SIGfield.

Abstract: A method of analyzing bonded part durability test result data provides a guide line for how much the thickness of a steel sheet forming a bonded part may be decreased while maintaining original equivalent durability of the bonded part. The method includes steps of: calculating a reference durability lifespan approximation function capable of estimating a durability lifespan value of a bonded part using a thickness value of at least one of two steel sheets; calculating a target durability lifespan approximation function capable of estimating the durability lifespan value of the bonded part; calculating an inverse function of the target durability lifespan approximation function capable of deriving a thickness value of the at least one steel sheet; and calculating any target steel sheet thickness value by substituting any target lifespan value into the inverse function of the target durability lifespan approximation function.

Abstract: A drum brake system adapted to transmit force to left and right levers for evenly contacting the left and right shoes to the drum when the driver depresses the brake pedal. The force is transmitted from a wheel cylinder, thereby resulting in an effective braking action due to the even contact between the drum and the shoes, and an improvement of the durability of components by preventing a partial wear and tear of the shoes.
