Abstract:
A motion assistance device has a biological signal detection means for detecting a biological signal from the wearer of the device; a motion assistance device installation member having a drive source for applying torque acting to the wearer by use of each joint of the wearer as a rotating shaft; a control means for controlling the drive source to generate torque corresponding to the biological signal detected by the biological signal detection mean; a drive torque estimation means for estimating the drive torque generated by the drive source; a joint angle detection means for detecting angular displacement of a joint; and a parameter identification means for substituting the drive torque estimated by the drive torque estimation means and the angular displacement detected by the joint angle detection means into an equation of motion to specify the wearer-specific dynamics parameter, the equation relating to the entire system and including wearer-specific dynamics parameter. The control means controls the drive source according to a predetermined control method, based on the equation of motion into which the dynamics parameter identified by the parameter identification means is substituted.
Abstract:
A massage machine for massage a user in a way that the rhythm and melody of a music source is taken in with as much fidelity as possible and the sequence of accents is more effectively arranged according to them. The massage machine has a massage mechanism (4, 5) for giving the body of the user a mechanical stimulation by driving motors (5a, 10, 11) and a controller (13) for controlling the operation of the motors. The controller (13) has a waveform converter (18) provided with waveform converting circuits such as a smoothing circuit, a differentiating circuit, an integrating circuit and adapted to convert the waveform of an acoustic signal inputted from a sound source (A) and a specific frequency band signal selector (17) provided with a low-pass filter, a high-pass filter, and a band-pass filter. The operation of the motors is controlled by control signals outputted from the waveform converter (18) and the specific frequency band signal selector (17).
Abstract:
A chair type massaging device being capable of treating the forearm of a subject in case of need, having no portion above the armrest that interferes with the placement of the arm when the forearm is not treated, and allowing the subject to take a free posture; and a forearm massaging machine used in this chair type massaging device. Therefore, the massaging device has a detachable member (38) installed on an armrest (5) for movement along guide rails (37), with a fitting groove (39) formed in the detachable member (38). A forearm massaging machine (7) constructed to be capable of grasping the forearm of a subject by a fixed support (46) and a gripper (47) to apply a pressing stimulus to the forearm is provided with a fitting projection (40). The forearm massaging machine (7) can be removably mounted on the armrest (5) by removably fitting the fitting projection (40) in the fitting groove (39).
Abstract:
The invention relates to a vehicle seat for a motor vehicle in which the seat cushion (2) and the seat back (3) are each provided with a number of elements (4), which can be pressurized and which can be controlled by a controller (5) in order to obtain different massage effects. The elements (4) that can be pressurized are cushion-like elements, which are small compared to the surface of the seat contour and which can each be separately controlled via lines (6) in order to alter the seat contour in an essentially punctiform manner.
Abstract:
An object of the present invention is to provide a massaging apparatus that faithfully incorporates rhythm or melody of a music source and perform massage with accents arranged more effectively based on these. A massaging apparatus of the present invention comprises massaging mechanisms (4, 5) that give mechanical impulses to a body by driving motors (5a, 10, 11), and a control device (13) that controls operations of the motors. The control device (13) comprises a waveform converter (18) having a waveform converting circuit for converting a waveform of an audio signal input from a sound source (A), such as a smoothing circuit, a differentiating circuit, or an integrating circuit, and a specific frequency band signal selecting unit (17) having a low pass filter, a high pass filter, and a band pass filter. In accordance with a control signal output from the waveform converter (18) and the specific frequency band signal selecting unit (17), the operations of the motors are controlled.
