The present invention provides a skin care device which performs optical care and thermal care in one device and minimizes noise that may occur in the skin measurement sensor, the device comprising: a housing for forming an outer appearance; a heat transfer bracket disposed at one end of the housing; a light source unit mounted on one end of the housing; a light transfer bracket including a light permeable material and fixed to the housing to cover the light source unit; a skin measurement sensor extending through a first hole formed in the light transfer bracket to protrude outward; and a first substrate mounted with the light source unit and spaced from the skin measurement sensor.

Skin care device

Disclosed is a skin care device which performs skin care under the condition that it is attached to a user's face, performs both skin care using light and skin care using microcurrent, and prevents electrical interference between light source elements and microcurrent elements. The skin care device includes a non-conductive flexible substrate, at least one light source element provided on the flexible substrate, microcurrent elements provided on the flexible substrate, an insulating layer provided with first holes to expose the at least one light source element and second holes to expose the microcurrent elements, and a conductive layer including a plurality of conductive parts, each conductive parts contacting each microcurrent element through each second hole, and the conductive parts are divided so as to be spaced apart from one another and are provided with third holes to expose the at least one light source element.

An electromotive walking assistance device includes a drive unit including a plurality of wheels and a motor for driving at least on portion of the plurality of wheels, a sensor unit sensing a distance from a user, a manipulation unit sensing a user's manipulation, and a controller controlling the motor based on a signal of the distance from the user and a signal of the user's manipulation.

Electric walking assistant device

A medical robotic system and method for controlling the system are provided to precisely measure contact force during the minimally invasive surgery. In one embodiment, a medical robotic system includes an input device, a robotic arm assembly, a surgical instrument operably coupled to the robotic arm assembly, the surgical instrument including a contact detection unit configured to detect a contact of the surgical instrument with tissue of a patient, a current measurement unit configured to measure a joint current in the robotic arm assembly, a position/velocity measurement unit configured to measure a joint position and a joint velocity in the robotic arm assembly, an external force calculation unit configured to calculate size and direction of a contact force caused by the contact of the surgical instrument to the tissue based on the joint currents, positions and velocities measured when the contact is occurred and measured when the contact is not occurred.
