A surgical device for ultrasonic ablation and RF cauterization includes a forceps member having at least one prong, the prong being formed as an electrode. The methods to determine the optimal trajectory of the control variables are discussed. By irradiating a second laser beam, region, on which particles were, is activated in the same manner as the region, on which particles are not, and p+-type collector layer is formed uniformly. The respective pairs of rotor magnets are arranged on the outer and inner cylinders while being spaced apart from each other by a predetermined interval. Through these embodiments, a flexible stringing member can dampen and dynamically narrow the pocket, enhance ball retention, increase passshot accuracy, and satisfy pocket-forming preferences. Initial device set up and installation, the viewing of device operation, the editing of various settings, and the viewing of historical energy usage information are made simple and elegant by virtue of the described form factor, display modalities, and user input modalities of the device.
