A method of decoding a one-point algebraic geometric code of dimension k and length n, in which, in order to identify the position of the errors in a received word, the syndromes matrix S, of size \xd7, is defined, of which the elements Sij of each line i are calculated, for j between 1 and w, where the boundary w is a decreasing function, using the syndrome s of the received word. In exemplary embodiments the mobile device reads an identifier from the point-of-sale device through wireless technology such as RFID. Dogs can also harm themselves by biting sharp material used to manufacture most standard water sprinklers. The massage motor may be located within the housing, within the massage node, or there may be multiple massage motors located in each of the housing and the massage node.
