In an electronic device, a pulse rate measuring unit measures user’s pulse rate. The pressure restrictor comprises a cylindrical member of a given diameter and length. Input streams from each endpoint are uncompressed, resized, and scaled to fit the segment in the layout for particular endpoints, and then encoded by a sub-encoder into a sub-encoded stream according to the compression parameters. The invention relates to specific scenting compositions comprising, in a cosmetically acceptable medium:a) at least 0.
