Abstract:
A liquid supply apparatus includes: a chamber configured to contain a liquid; an injector disposed on a first side of the chamber and configured to spray the liquid; and a piston extending from a second side of the chamber toward an interior of the chamber, wherein the chamber includes a first area configured to store the liquid; and a second area between the first area and the injector, and wherein the piston is configured to selectively seal or transfer the liquid between the first area and the second area, and press the liquid in the second area to expel the liquid from the liquid supply apparatus.
Abstract:
There are provided a composition, a light-emitting device including the composition, and an electronic apparatus including the light-emitting device, wherein the composition includes a first compound including at least one pyrrole-containing condensed cyclic group and a silicon-containing group, and not including an electron-transporting moiety, and a second compound including an azine group including at least one nitrogen, and not including a silicon-containing group.
Abstract:
A walking assistance method may include measuring a current gait motion of a user, defining a state variable based on the current gait motion, setting a delay that is a feedback element for the state variable, and generating a torque profile based on the state variable and the delay.
Abstract:
Provided is an assisting torque setting apparatus and method, wherein the apparatus is configured to calculate an evaluation value of at least one index based on gait data of a user, set a stable assisting torque based on the evaluation value, set a basic assisting torque corresponding to a gait motion of the user based on the gait data, and set a final assisting torque based on the stable assisting torque and the basic assisting torque.
Abstract:
A walking assistance method and/or apparatuses configured to perform same are provided. A state variable may be defined based on a result obtained by measuring a gait motion of a user, and a torque profile may be generated based on the defined state variable, a gain and a delay. The generated torque profile may correspond to a torque profile to assist the gait motion, or a torque profile to provide a resistance to the gait motion.
Abstract:
A device according to one disclosed embodiment comprises: a control part which determines at least one target frequency of an MRI noise signal generated in an MRI device and generates a control signal for the determined target frequency; and an output part which outputs the control signal, wherein the target frequency is the frequency of the MRI noise signal to be controlled and the control signal is a signal in which at least one of the size and the phase of the MRI noise signal is changed.
Abstract:
Provided is a motion assistance apparatus including a fixing module to be attached to a waist of a user, a driving module provided in the fixing module to provide a torque to assist a motion of the user, a supporting module connected to the driving module to support a portion of a circumference of a leg of the user, and a controller configured to control the driving module to provide a torque to maintain a close contact between the supporting module and the leg of the user while the user is not walking.
