Patent number: 11965921Abstract: A measurement system and method tests for spurious emissions included in a signal transmitted from a mobile terminal in a shorter time than before. The system includes: a band division unit for dividing the measurement frequency band into a plurality of divided bands; a first spurious measurement control unit which causes a measurement device to measure the spurious emissions of the signal to be measured in each divided band and the peak power of the spear in each divided band; and a first pass/fail determination unit that determines whether or not pass determination criteria is satisfied. The first pass/fail determination unit determines whether the peak power does not exceed the threshold of the pass determination criteria in each divided band. The threshold value of the pass determination criteria is lower than the threshold of the standard determination criteria defined by the 3GPP standard.Type: GrantFiled: September 21, 2022Date of Patent: April 23, 2024Assignee: ANRITSU CORPORATIONInventors: Hiroaki Iida, Koki Iwata, Kayoko Horiuchi

Patent number: 9020199Abstract: A secondary curve, the ends of which coincide with the inner corner and the outer corner of the eye, is determined successively, and the total of the edge values of the pixels overlapping the secondary curve is calculated as an evaluation value. Next, a characteristic curve is generated on the basis of data made up of the calculated evaluation value and the Y-coordinate of the intersection between the secondary curve and a straight line passing through the center of a line segment whose ends coincide with the inner corner and the outer corner of the eye. Then, the reference positions for the upper eyelid and the lower eyelid of the eye are set on the basis of the result of an attempt to detect a pixel group occurring because of the red-eye effect in a search area defined on the basis of peaks in the characteristic curve.Type: GrantFiled: April 19, 2011Date of Patent: April 28, 2015Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Takashi Hiramaki, Atsushi Nakabayashi, Masayuki Usami, Tamiko Nishina, Hiroaki Iida
