An apparatus and method of generating personal fonts is provided, which can modify a trace of handwriting inputted by a user into an elegant one and generate diverse personal fonts in accordance with user’s style of handwriting. For each candidate motion vector, encoding distortion is determined between a macroblock and a reconstructed macroblock by determining discrete cosine transform coefficients of the macroblock and quantizing the discrete cosine transform coefficients. More, specifically, the valves of the present invention may be used to control the flow of a blasting media into an air stream as part of a blasting apparatus for treatment of a surface. During use, the combined effect of the resonance of the second resonator element and of the feed line and ground plane is to cause the antenna structure to resonate in the third operating frequency band. The at least one ensnarement feature is disposed at least partially proximally relative to the guide feature. The method is particularly suitable for brewing a tea containing capsule.
