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 processing apparatus is provided. The processing apparatus includes a processing portion, an actuator, a casing, a preload mechanism, a force sensor, and a detection unit. The processing portion includes a cutting edge. The actuator is configured to cause the processing portion to vibrate microscopically. The casing is configured to accommodate the actuator. The preload mechanism is disposed inside the casing and configured to impart a preload to the actuator. The force sensor is disposed between the cutting edge and the preload mechanism. The detection unit detects a cutting force of the processing portion based on an output of the force sensor.
