A laser system and techniques which compensate for laser fluence drop off or losses of irradiation as an ablating laser beam is traversed on a curved surface. The ring gear has a gear portion formed on a first side surface thereof, which first side surface faces the input shaft and is positioned along the axis of the driving axles, for being operatively connected with the input shaft, and forms an axle hole through which an inner end of one of the right and left driving axles relatively rotatably passes. Moreover, the heat sink has a thickness of 500 \u03bcm to 2 mm, and may be formed to be thicker than the semiconductor substrate. If it is determined that the hardware graphics pipeline is operating in the programmable mode, programmable operations are performed on the fragment data in order to generate output. The dongle plugs into a data port on the vehicle and allows both the fob and the electronic device to communicate with the vehicle in order to control functions of the vehicle.
