Patent number: 8251930Abstract: A walking assistance device (1) has a body-mounted assembly (2) installed on the waist of a user (A), foot-mounted assemblies (3L, 3R) installed on feet, and leg links (4L, 4R) which connect the foot-mounted assemblies (3L, 3R) to the body-mounted assembly (2). The foot-mounted assemblies (3L, 3R) are provided with floor reaction force sensors (13L, 13R). Results obtained by multiplying the absolute values of floor reaction force vectors (three-dimensional vectors) detected by the floor reaction force sensors (13L, 13R) by a predetermined ratio are defined as target values of the magnitudes of the supporting forces transmitted to the leg links (4L, 4R) from the foot-mounted assemblies (3L, 3R). Actuators (20L, 20R) of the leg links (4L, 4R) are controlled such that the supporting forces having the magnitudes of the target values act on the leg links (4L, 4R) from the foot-mounted assemblies (3L, 3R) through the intermediary of joints (19L, 19R).Type: GrantFiled: June 5, 2006Date of Patent: August 28, 2012Assignee: Honda Motor Co., Ltd.Inventor: Tetsuya Ido

Publication number: 20120095373Abstract: A walking assistance device applies a walking assistance force from an electric motor to a femoral part of a user. The device comprises a communication unit and an operation switch enabling unit. The operation switch enabling unit disables an operation switch of the walking assistance device until the communication unit receives a signal from an external device even when a power switch is turned on, and enables the operation switch when the communication unit has received a signal from the external device while the power switch is turned on. Thus, unauthorized use of the walking assistance device is prevented, and operation of the walking assistance device is supervised with control parameters suited for the particular user. Also, the walking assistance device can be shared by a plurality of users, and each user can use the walking assistance device with pre-selected control parameters that optimally suit the particular user.Type: ApplicationFiled: September 22, 2011Publication date: April 19, 2012Applicant: HONDA MOTOR CO., LTD.Inventors: Takashi Hirata, Tetsuya Ido, Hideo Shimizu

Publication number: 20050105771Abstract: The object detection apparatus according to the invention detects an object based on input images that are captured sequentially in time in a moving unit. The apparatus generates an action command to be sent to the moving unit, calculates flow information for each local area in the input image, and estimates an action of the moving unit based on the flow information. The apparatus calculates a difference between the estimated action and the action command and then determines a specific local area as a figure area when such difference in association with that specific local area exhibits an error larger than a predetermined value. The apparatus determines presence/absence of an object in the figure area.Type: ApplicationFiled: August 30, 2004Publication date: May 19, 2005Inventors: Shinichi Nagai, Hiroshi Tsujino, Tetsuya Ido, Takamasa Koshizen, Koji Akatsuka, Hiroshhi Kondo, Atsushi Miura
