An optical semiconductor device includes a silicon oxide layer configured to be formed on a substrate; an optical waveguide part configured to be formed on the silicon oxide layer; a cladding layer configured to be formed covering the optical waveguide part; and a semiconductor laser configured to be disposed on the substrate. The groups of radio resources are nonoverlapping in time, frequency andor code. When the processed signals indicate re-acceleration of the vehicle, the electronic controller activates an aggressive schedule or aggressive throttle map that defines instructions for downshifting a transmission gear position or for increasing a throttle so as to assist in acceleration of the vehicle during re-acceleration. The drip pan can hold a liquid, and the aperture and inner sidewall form a passage for infrared radiation through the liquid. The information is stored in the HLR, and when the location service node in the network receives a location request for that MS, the location node invokes the HLR for the information. Thus the auto-balancing apparatus can achieve a balance effect at low rotation speeds.
