The present disclosure relates to a laundry treatment machine. A laundry treatment machine according to an embodiment of the present disclosure including an inverter to convert the DC voltage from the converter into an alternating current (AC) voltage based on a switching operation and to output the converted AC voltage to the drain motor; and a controller to control the drain motor to operate at any one of a first speed, a second speed less than the first speed, and a stop when the washing tub motor is accelerated. Accordingly, according to the operation of the washing tub motor, it is possible to efficiently drive the drain motor.

Laundry treatment machine

The present disclosure relates to a laundry treatment machine. A drain laundry treatment machine according to an embodiment of the present disclosure: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a drain motor; an output current detector to detect an output current flowing in the drain motor; and a controller to control the drain motor to rotate at a speed lower than a first speed when the output current flowing in the drain motor decreases in a state where a speed of the drain motor is the first speed. Accordingly, it is possible to reduce a pressure in a vortex chamber of the drain pump during dewatering.

Disclosed herein is a surgical operation by wire (SOBW) type surgical operation apparatus including an end effector configured so as to remove or minimize configurations of a mechanical cable. The SOBW type surgical operation apparatus includes: a body part; an extension part having one end connected to the body part; and an end effector formed at the other end of the extension part, and receiving electrical energy transferred through the body part and the extension part and converting the electrical energy into mechanical energy.

Surgical operation by wire type surgical operation apparatus

Disclosed herein is a surgical robot control apparatus, in which a control stick member is connected to an upper surface of a base member, pivots and rotates around a connection portion, and is provided with a rotary button control member, a mode switching button member, and a control member which can be operated with the thumb. Thus, the surgical robot control apparatus can realize multiple functions. A surgeon can grasp the control stick member to easily control operation of a surgical robot and can perform other work using the other hand. Thereby, when performing surgery, the surgical robot control apparatus remarkably reduces the fatigue of the surgeon, thereby providing a surgical environment that is convenient and safe; and which provides maximized efficiency. Further, the surgical robot control apparatus can increase the safety of a patient using a safety device based on a buttons, software, and hardware while performing surgery.

Provided is a system and method for evaluating laser treatment, for converting the attribute of a laser beam and numerically evaluating proficiency of a laser treatment operator by processing data obtained by photographing the converted laser beam so as to use the evaluated data as training data. The laser treatment evaluating system includes an attenuation unit for attenuating intensity of a laser beam transmitted through a transmissive plate, a camera for photographing the laser beam transmitted through the attenuation unit, and an image data processing apparatus connected to the camera, for processing an image captured by the camera, tracking a trajectory of a laser beam on the transmissive plate, and calculating a distribution state of spots on which the laser beam on the transmissive plate is emitted.

System and method for evaluating laser treatment

Disclosed herein is a maneuverable capsule endoscope. A capsule body is input into an internal organ to take images of the inside of the internal organ. A fan unit is mounted on the body. A fan position-changing device changes a direction in which the fan unit discharges fluid. The fan unit is mounted inside a duct without damaging the inner wall of the internal organ. When input into the internal organ, the capsule endoscope can concentrically take images of a specific portion inside the internal organ, and can freely take images of a portion that is intended to be photographed.
