Abstract: A massage pin for skin blood circulation promoters has a lower end to/from which a silver conductor having stable electrical resistance is coupled or separated by a user of a skin blood circulation promoter, as needed. The massage pin includes: a coupling portion formed at an upper end of the massage pin and press-fitted into a circuit board disposed between a main body and a cover of a blood circulation promoter, the coupling portion being formed of a conductive rubber. An exposed portion extends from a lower end of the coupling portion and is exposed outside through a massage pin-passage hole formed through the cover. The exposed portion has a downwardly tapered connection portion extending from a lower end thereof and includes a silver conductor detachably coupled to the connection portion. The conductor has a reception portion open at an upper portion thereof.

Abstract: Provided is a method of encoding and decoding texture coordinates of 3D mesh information. The method of encoding texture coordinates in 3D mesh information includes the steps of: setting an adaptive quantization step size used for quantizing the texture coordinates; quantizing the texture coordinates using the adaptive quantization step size; and encoding the quantized texture coordinates.

Abstract: A method and apparatus for encoding and decoding three dimensional (3D) mesh information, especially, for outputting data in a decoding process with the number of digits of original data are disclosed. One embodiment of the present invention comprises 3DMC mesh data encoding at a transmitting end for counting the number of digits of original data and generating a 3DMC packet including an encoded original data and the digit number, transmitting the 3DMC packet to a receiving end, and 3DMC mesh data decoding at the receiving end for reconstructing and outputting the encoded original data based on the number of digits. According to one embodiment of the invention, the fidelity of data reconstruction is increased.
