  • Publication number: 20100245051
    Abstract: A communication method for a noncontact RF ID system that uses a first waveform, a second waveform, and a third waveform, wherein the first waveform and the second waveform are formed by a basic waveform having one of a rising or falling state transition at the approximate center of the waveform, the third waveform is formed by a plurality of basic waveforms that have one state transition at the approximate center part of the waveform, and the third waveform generates one state transition only at the approximate center of the plurality of basic waveforms. In addition, communication is carried out by using the third waveform in place of the first waveform and the second waveform in the case in which communication is carried out using a first waveform and a second waveform and one state transition is generated outside the approximate center part of the basic waveform.

  • Publication number: 20040143497
    Abstract: An inputting terminal transmits encoded advertisement type information. A server receives the advertisement type information from the inputting terminal and stores the number of encoded advertisement type information receipts. A computer 20 calculates an advertisement effect according to the number of receipts and calculates an advertisement fee according to the calculated advertisement effect. By doing this, it is possible to provide an advertisement effect analyzing method having a function in which it is possible to understand the advertisement effect quantitatively and calculate the incentive according to the increase in the viewers of the advertisement by receiving information directly from the viewers that indicates that the viewer acknowledged the advertisement.
