Abstract:
Disclosed herein is a method of converting and reconstructing a signal, including: at a data generator, acquiring signal-analyzed data from an original signal, wherein the signal-analyzed data includes at least one feature point acquired from the original signal; transmitting and receiving the signal-analyzed data and at least one reference data corresponding to the signal-analyzed data; and reconstructing the original signal based on the signal-analyzed data and the at least one reference data to acquire a reconstructed signal.
Abstract:
A muscular strength assisting apparatus may include: a wearing unit configured to enclose a part of a user's body; a tightening unit configured to pull the wearing unit in one or both directions; and/or a control unit configured to drive the tightening unit to tighten the part of the user's body on which the wearing unit is located, when it is determined that muscular contraction occurs at the part of the user's body on which the wearing unit is located. A method of controlling a muscular strength assisting apparatus may include: determining whether muscular contraction occurs at a part of a user's body that is enclosed by a wearing unit; and/or driving a tightening unit pulling the wearing unit in one direction or both directions to tighten the part of the user's body on which the wearing unit is located when it is determined that the muscular contraction occurs.
Abstract:
A walking assistance method may include: computing an amount of exercise of a user based on a biosignal of the user; adjusting a pattern of an assist parameter based on the amount of exercise; and/or generating a force corresponding to the amount of exercise, based on the adjusted pattern. A walking assistance apparatus may include: a pattern adjuster configured to compute an amount of exercise of a user based on a biosignal of the user; and/or a driver configured to generate a force corresponding to the amount of exercise based on a pattern of an assist parameter based on the amount of exercise.
Abstract:
A three dimensional (3D) imaging system capable of effectively displaying a 3D image suitable for a user by use of different cameras, and an image reproducing method thereof, the 3D imaging system configured to have different cameras freely selected without restriction while enabling the placement of the cameras thereof to be changeable according to the disposition of eyes of the user, so that a 3D image is generated and displayed from a stereo image adapted to the user, and by using the by-user generated 3D image, various contents services including a real time broadcasting, a Contents on Demand (COD), games, and a video communication are provided to a user, so that the fatigue or dizziness of a user is reduced, and the optimum perception of 3D sense is provided.
Abstract:
Disclosed herein is a wearable robot for assisting a wearer's intended motion, including: one or more links configured to support the wearer; one or more joints unit configured to connect the links to each other; a controller configured to determine the wearer's intended motion, and to calculate at least one torque based on the wearer's intended motion; and a driver configured to generate the calculated torque in the joints. According to the wearable robot, a wearer's intended motion may be determined in real time based on a velocity of the wearer's center of gravity. At this time, by using a pressure sensor, reliability of the motion determination may increase. Also, joint movements may be effectively controlled according to the wearer's intended motion.
Abstract:
Disclosed are a joint protection apparatus and a control method thereof. The joint protection apparatus includes a support unit, to which different support frames are coupled via a hinge, a fastening adjustment unit coupled to the support unit to provide fastening force required to fasten the support unit to a human body, a sensing unit configured to sense motion of the different support frames, and a controller configured to decide a motion region in which the motion sensed by the sensing unit is included and to decide the fastening force of the decided motion region.
Abstract:
There are provided a wearable robot and a method of controlling the same. The method includes obtaining a joint angle and a joint angular velocity of a plurality of joints, calculating a target joint angle of one joint among the plurality of joints using a joint angle and a joint angular velocity of at least one joint among the other joints, calculating assistive torque to be applied to the one joint using the calculated target joint angle, and outputting the calculated assistive torque to the one joint.
Abstract:
Disclosed herein are a walking assistance apparatus including a drive portion capable of adjusting tension of a fixing portion, and a method of controlling the same. The walking assistance apparatus includes a support portion which applies assist power to assist walking to a human body, a fixing portion which is arranged at one end of the support portion to enclose the human body and fixes the support portion on the human body, a drive portion including at least one motor which adjusts tension of the fixing portion, and a control portion which adjusts a driving direction of the at least one motor during rotation of the support portion in order to prevent the fixing portion from rotating by assist power applied through the support portion.
Abstract:
Provided is a method of controlling a wearable robot, the method including: measuring a ground reaction force (GRF) exerted on a wearer's soles; calculating a time variation rate of the measured GRF; measuring the wearer's knee joint angle; and detecting a time point at which the calculated time variation rate of the GRF and the measured knee joint angle cross each other.
