Abstract: Disclosed is a fan-out buffer which includes a first channel that includes a first delay circuit adjusting a first delay time of a calibration test signal depending on a first delay control signal, a second channel that includes a second delay circuit adjusting a second delay time of the calibration test signal depending on a second delay control signal, a first edge-to-pulse converter that detects a first edge included in a first time domain reflectometry (TDR) waveform of an output terminal of the first channel and generates a first start pulse signal including a first pulse, a second edge-to-pulse converter that generates a second start pulse signal including a second pulse, a stop pulse signal generator that generates a stop pulse signal including a first stop pulse, and a first delay control signal generator that calculates a phase difference generates the first delay control signal.

Abstract: According to one embodiment of the present invention, a knee brace comprises: an upper brace positioned at a thigh region of a wearer when the knee brace is worn; a lower brace positioned at a shin region of the wearer when the knee brace is worn; and a reciprocal hinge connecting the upper brace to the lower brace such that the lower brace is rotatable with respect to the upper brace.

Abstract: Provided is an anastomosis device including a first head holding a first anastomosis ring, a second head holding a second anastomosis ring, a first guide bar connected to the first head and switching a release position and a standby position to each other, wherein the first guide bar includes a first rotation groove, a second guide bar connected to the second head and switching the release position and the standby position to each other, wherein the second guide bar includes a second rotation groove, and a rotation driver moving approximately in a parallel direction to the first and second guide bars and including a first guide protrusion and a second guide protrusion, which move along the first and second rotation grooves, respectively.

Abstract: Provided is an anastomotic device including a first holder and a second holder for holding a first anastomotic ring and a second anastomotic ring, respectively, a first slave body which is connected to the first holder, and which has a first slave surface, a second slave body which is connected to the second holder, and which has a second slave surface, a first driving body which has a first driving surface sliding along the first slave surface, and which moves along a predetermined direction, and a second driving body which has a second driving surface sliding along the second slave surface, and which moves along the predetermined direction. The first slave body moves toward the second slave body and the second slave body moves toward the first slave body by the movements of the first driving body and the second driving body.
