Patent number: 11678837Abstract: The objective of the present invention is to provide a hardness meter which estimates hardness in a stable manner regardless of a compression strength. A hardness meter includes: a movable portion which is continuously pressed against an object to be measured; a sensor which outputs an output signal reflecting a reaction force at a part of the object to be measured; a motive force mechanism that causes the movable portion to perform a piston motion; a hardness estimating portion which estimates the hardness of the object on the basis of an alternating current component of the output signal, generated by the piston motion; a position estimating portion which estimates a measurement position information by shooting with a camera; and a hardness map display portion which maps and displays the hardness on a schematic diagram of the surface of a living body based on the measurement position information.Type: GrantFiled: April 22, 2022Date of Patent: June 20, 2023Assignee: Maxell, Ltd.Inventors: Yuko Sano, Akihiko Kandori, Mitsuo Okimoto, Shigemitsu Ando, Mitsunobu Watanabe

Patent number: 11619572Abstract: An object of the present invention is to provide a durometer enabling a contact portion in contact with an object to perform smooth piston motion. The durometer includes a main body unit including a movable unit pressed continuously against an object to be measured, a first sensor outputting acceleration information corresponding to an acceleration of movement of a contact part of the object to be measured in contact with the movable unit in a pressing direction, a second sensor outputting reactive force information corresponding to a reactive force at the contact part of the object to be measured in contact with the movable unit, a motor, a crank mechanism driven by the motor and causing the main body unit and the movable unit to perform piston motion, and at least one buffering member disposed on a periphery of the main body unit.Type: GrantFiled: July 13, 2021Date of Patent: April 4, 2023Assignee: Maxell, Ltd.Inventors: Akihiko Kandori, Yuko Sano, Yuhua Zhang, Shigemitsu Ando, Mitsunobu Watanabe, MItsuo Okimoto
