Patent number: 11161357Abstract: An information processing apparatus includes an acquisition unit, a decision unit, a determination unit, and a change unit. The acquisition unit acquires a measurement result regarding a printing medium characteristic value. The decision unit decides a candidate for a printing medium type based on the acquired measurement result, and a reference characteristic value of each of printing media types set in advance to identify a type of the measured printing medium. Information associated with the printing medium type to be printed is input. The determination unit determines whether to change the reference characteristic value of the printing medium type associated with the input information based on the measurement result and the printing medium type associated with the input information. Wherein, when the determination unit determines to change the reference characteristic value, the change unit changes the reference characteristic value of the printing medium type based on the measurement result.Type: GrantFiled: February 21, 2020Date of Patent: November 2, 2021Assignee: Canon Kabushiki KaishaInventors: Takehiko Kasamatsu, Yuki Igarashi, Koji Suda, Fumikazu Nishikawa, Yasushi Morimoto, Keiko Harada, Ryoma Ono

Patent number: 10205587Abstract: Provided is a wireless communication system which enables wireless communication in which crosstalk due to multiple access is canceled while using a large number of inexpensive wireless terminals. In order to generate an interference component, an analysis data sequence is generated by applying a Hilbert transform, by a Hilbert transform, to a subcarrier data sequence obtained by extracting a target subcarrier wave component from a finite length data sequence, while a carrier phase difference ? is estimated by using the regression analysis by a carrier wave phase estimation unit. After rotation calculation configured to return the analysis data sequence by the carrier phase difference ? is performed, conversion into an angle is performed. Further, a multiplication by a desired odd number of multiplication is performed, and then an inverse Hilbert transform is applied.Type: GrantFiled: April 24, 2017Date of Patent: February 12, 2019Assignee: KYOWA ELECTRONIC INSTRUMENTS CO., LTD.Inventors: Jin Mitsugi, Yuki Igarashi, Haruhisa Ichikawa, Yuusuke Kawakita, Kiyoshi Egawa
