A drill bit having features rendering it particularly effective in cutting holes in carboresin laminates of the type used in the aircraft industry. The multifunctional thermal conducting andor radiating particle is composed of a core and a shell, wherein the core includes a core particle having a lower thermal conductivity than that of a particle included in the shell, and the shell includes high-thermal conductive particles each having a higher thermal conductivity than that of the core particle. In exemplary embodiments of the invention, the improved pointing device may be operated at least in part by, for example, several of a user’s fingers, by a foot, or by a user’s eyes. An electronic circuit is mounted within the first chamber. The method of the present invention includes the steps of offering used goods, owned by an actual seller, for sale over an internet exchange portal; selling a right to market the used goods to a virtual seller; marketing the used goods over the portal under direction of the virtual seller; identifying an actual buyer; and selling the used goods to the actual buyer. To reduce artifacts and improve quality, several steps are implemented including spatial variation extraction, determining if a block is flat or textureedge, classifying the pixels as texture or noise, detecting a dominant edge, checking the spatial variation of neighboring blocks, generating base weights, generating filter coefficients, filtering pixels and adaptive enhancement.
