Publication number: 20170255817Abstract: A computer-readable recording medium storing a displacement determination program is disclosed. First and second face areas of a person are extracted, respectively, from first and second images captured by first and second imaging devices arranged at certain positions where first and second available ranges for detecting a gaze are overlapped. First and second feature points are detected based on light reflections in the first face area and the second face area being extracted. First and second gaze positions of the person are calculated based on the first and second feature points being detected. An arrangement displacement is determined from both or one of the certain positions of the first and second imaging devices based on a relative position relationship between the first and second gaze positions.Type: ApplicationFiled: January 17, 2017Publication date: September 7, 2017Applicant: FUJITSU LIMITEDInventors: HIDEKI TOMIMORI, Satoshi NAKASHIMA

Patent number: 9247892Abstract: A heartbeat signal method includes detecting first and second heartbeat signals, where the first and second heartbeat signals may be potential difference signals with respect to a reference potential. First and second average DC voltage values as voltage values of direct-current components in the first and second heartbeat signals are calculated. First and second average AC amplitude values as amplitude values of alternate-current components in the first and second heartbeat signals are calculated, and a correlation coefficient between the alternate-current component in the first heartbeat signal and the alternate-current component in the second heartbeat signal is calculated. An amplification factor is set to amplify the first or second heartbeat signal on the basis of the first and second average DC voltage values, the first and second average AC amplitude values, and the correlation coefficient.Type: GrantFiled: May 5, 2014Date of Patent: February 2, 2016Assignee: FUJITSU LIMITEDInventors: Hideki Tomimori, Satoshi Sano

Patent number: 9000931Abstract: A noise processing apparatus measures a first potential difference signal, between a first electrode and a second electrode that is used as a reference electrode, and measures a second potential difference signal, between the second electrode and a third electrode that is arranged on the steering unit in the apparatus. The apparatus calculates the difference between the intensities of the first potential difference signal and the second potential difference signal calculated at the predetermined intervals. The apparatus corrects the first potential difference signal or the second potential difference signal by using the calculated difference such that the intensities of the first potential difference signal and the second potential difference signal are canceled out.Type: GrantFiled: May 30, 2012Date of Patent: April 7, 2015Assignees: Fujitsu Limited, The University of TokyoInventors: Hideki Tomimori, Ken Sasaki, Yasuhiko Nakano, Satoshi Sano, Yoshio Ishida
