Patent number: 11960149Abstract: Provided is technology that makes it possible to measure visual behavior with respect to objects that are at different distances in the depth direction, while reducing burden on a subject. A method for measuring visual behavior of a subject to design an eyeglass lens includes: a step (a) of ascertaining a head rotation amount that is generated by the subject in a sagittal plane of the subject when gazing at each of a plurality of gaze points that are set at predetermined distances different from each other in a forward depth direction; and a step (b) of determining an eyeball rotation amount that is generated by the subject when gazing at each of the plurality of gaze points, based on the head rotation amount.Type: GrantFiled: September 30, 2021Date of Patent: April 16, 2024Assignee: HOYA LENS THAILAND LTD.Inventors: Eiichiro Yamaguchi, Toshiaki Sonehara, Ayumu Ito

Publication number: 20180354362Abstract: An accelerator pedal assembly of a vehicle can include a pivotable arm including a moveable end that is movable through a plurality of pedal positions from an initial position to a fully engaged position. The accelerator pedal assembly can also include a pedal connected to the moveable end of the pivotable arm. The accelerator pedal assembly can further include a reaction force control assembly connected to the pivotable arm and configured to apply a reaction force to the pivotable arm. The reaction force control assembly can include a first mode in which the reaction force increases as the pedal position approaches the fully engaged position in accordance with a first relationship, and a second mode in which the reaction force increases as the pedal position approaches the fully engaged position in accordance with a second relationship that is different from the first relationship.Type: ApplicationFiled: June 9, 2017Publication date: December 13, 2018Inventors: Yoshinori KUNIMURA, Akihiko KOIKE, Ayumu YAMAGUCHI

Patent number: 9927830Abstract: A reaction force output device includes: a motor that is a drive source that creates a reaction force; a reaction force output shaft that interlocks with an output shaft of the motor to rotate; and an interlocking arm that transmits output torque of the motor which is input to the reaction force output shaft to an operation pedal. A torque limiting mechanism, which limits the transmission of torque that is equal to or greater than a specified value between the reaction force output shaft and the interlocking arm, is interposed between the reaction force output shaft and the interlocking arm.Type: GrantFiled: September 17, 2014Date of Patent: March 27, 2018Assignees: Honda Lock Mfg. Co., Ltd., Honda Motor Co., Ltd.Inventors: Hiroyuki Kouzuma, Kohei Hirotani, Hideto Nebuya, Ayumu Yamaguchi, Go Suzaki, Kohei Maruyama

Patent number: 9475386Abstract: A vehicle accelerator pedal apparatus including: a pedal-side arm supported, so as to allow rotation toward the front and rear of the vehicle, by a support shaft in a housing; a pad in the pedal-side arm that can be operated by stepping; and a reaction force application mechanism for applying reaction force to the pedal-side arm. The reaction force application mechanism includes a drive source for generating the reaction force, and a transmission member for transmitting the reaction force generated by the drive source to the pedal-side arm. The reaction force application mechanism is arranged higher than the housing. The pedal-side arm has an extension part that is extended on the opposite side from the pad across the support shaft, and from the pedal-side arm to the transmission member.Type: GrantFiled: October 4, 2013Date of Patent: October 25, 2016Assignee: Honda Motor Co., Ltd.Inventors: Yosuke Horiuchi, Hideto Nebuya, Motomasa Suzuki, Ayumu Yamaguchi, Mitsunori Hirai, Kiyohiro Mando
