Abstract:
The present invention relates to a massage device comprising: a support, and a plurality of massage elements, each projecting a distance outwardly from the support and having a rounded massaging surface, characterised in that at least some of the massage elements project outwardly from the support by a first distance, and at least others of the massage elements project outwardly from the support by a second distance, whereby the first and second distances are different. The present invention provides a massage device comprising a massage surface consisting of closely packed massage elements set at different heights. The massage elements are provided by hemispheres each having a rounded upward facing massage surface, that interface with the skin to trigger a powerful unwind and relaxation response from the strained area of contact and peripheral to it. The device is a passive massage device without moving parts.
Abstract:
A method for estimating posture of robotic walking aid(1) includes: providing a motor controller(50), a motor encoder(71) and a motor(70) on right and left hip joints, and right and left knee joints of the robotic walking aid(1), providing an inertial sensor(60) on upper body(40) of the robotic walking aid(1), wherein the motor controller(50), the motor encoder(71), the motor(70) and the inertial sensor(60) are coupled to a control unit(80); installing the robotic walking aid(1) on a user; inputting the lengths of the upper body(40), two thighs, two shanks, two feet of the robotic walking aid(1) to the control unit(80), wherein the upper body(40), two thighs, two shanks, two feet form a plurality of points; obtaining an angle of the upper body(40) corresponding to a reference frame with the inertial sensor(60); obtaining angles of those joints with those motor encoders(71); and calculating 3 dimensional coordinates of each point with a motion model.
Abstract:
A method and apparatus for calculating a torque of a walking assistance device, the method including receiving a measured joint angle, obtaining a gait parameter with respect to a transition among a predetermined number of gait states based on the joint angle, obtaining a gait cycle based on the joint angle, and obtaining an output torque based on the gait cycle and the gait parameter, is provided.
Abstract:
A wearable action-assistance device is provided with which an assistant can intuitively perform settings for operation of the device while assisting a wearer during walking and without leaving the wearer. An operation unit (140) includes a display (141), task selection buttons (142), joint buttons (143), a stop button (144), a start button (145), arrow keys (146) and a confirmation operation button (147). As shown in the drawing, the joint buttons (143) are operation buttons for displaying assistive force settings and operating states relating to each joint on the display (141). The joint buttons (143) consist of a left hip joint button (143a), a left knee joint button (143b), a right hip joint button (143c) and a right knee joint button (143d), and the respective joint buttons are disposed on the upper left, lower left, upper right and lower right of the operation unit (140).
Abstract:
A working posture holding device (10) includes: a lower back holding part (11) that holds a lower back of a user; a leg part (12a) that supports the lower back holding part, the leg part being rotatably connected to the lower back holding part, the leg part extending along a leg region of the user; a foot part (13a) that is connected to the leg part, the foot part contacting a ground to support the overall working posture holding device; a fixing part (14a) that fixes the leg part and the user to each other; and a locking mechanism (15a) that switches a state of the leg part between a "variable" state where a distance between a connection part to the lower back holding part and a connection part to the foot part is variable, and a "locked" state where the distance is fixed, wherein when the locking mechanism sets the leg part to be in the locked state, the lower back holding part holds a lower back of the user to hold a standing posture of the user and, when the locking mechanism sets the leg part to in the variable state, the user is able to walk.
Abstract:
A lower extremity exoskeleton (100), configurable to be coupled to a person, includes two leg supports (101, 102) configurable to be coupled to the person's lower limbs, an exoskeleton trunk (109) configurable to be coupled to the person's upper body, which is rotatably connectable to the thigh links (103, 104) of the leg supports (101, 102) allowing for the flexion and extension between the leg supports (101, 102) and the exoskeleton trunk (100), two hip actuators ( 145, 146) configured to create torques between the exoskeleion trunk (109) and the leg supports (101, 102), and at least one power unit (201) capable of providing power to the hip actuators (145, 146) wherein the power unit (201) is configured to cause the hip actuator (145, 146) of the leg support (101, 102) in the swing phase to create a torque profile such that force from the exoskeleton leg support (101, 102) onto the person's lower limb during at least a portion of the swing phase is in the direction of the person's lower limb swing velocity.
