The invention pertains to optical fiber transmission systems, and is particularly relevant to optical transport systems employing Raman optical amplifiers. By utilizing this thin film with specific properties the sealers may be operated at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The first flange is in contact with the body and extends away from the body. The frame’s articulations allow the splint to fit the curve of the dental arch and to adapt to irregularities in the teeth’s position. The compressed downsampled data can be used to generate a frame at the reduced resolution. To achieve said objective, an antenna electrode is provided on the surface of the main body, a grounding electrode is provided on the back face, and a signal electrode is provided on the circumferential face, the antenna electrode being different in length at the X axis from the Y axis.
