Provided is a method of detecting the R peak of an electrocardiogram (ECG) signal using an adaptive median filter. The method includes allowing an ECG signal (hereinafter, referred to as a first ECG signal) received from an ECG signal measuring apparatus having a predetermined sampling rate to pass through an adaptive median filter, calculating a difference value between the first ECG signal and a signal (hereinafter, referred to as a second ECG signal) passing through the adaptive median filter, extracting R peak candidate groups by applying a maximum filtering size and an adaptive threshold applicable in the adaptive median filter to the calculated difference value between the first and second ECG signals, and detecting an R peak candidate group having a maximum value among the R peak candidate groups as an R peak.

Apparatus and method for detecting R peak of ECG signal using adaptive median filter

Provided are an apparatus and method for detecting ventricular depolarization (QRS) of an electrocardiogram (ECG). The apparatus includes an input unit configured to receive an ECG signal, a memory configured to store a program for detecting R and ventricular depolarization using the ECG signal, and a processor configured to execute the program, wherein the processor detects a QRS interval and an R-peak using a first-order derivative filter and a max-filter.

Apparatus and method for detecting QRS of ECG

An automatic hair implanter is capable of continuously performing hair transplantation work by applying a structure of a conventional manual hair implanter. The automatic hair implanter (hair transplantation device) comprises a rotating magazine therein, and several needle modules are stored in the magazine. Two pushrods, which are positioned on a rear portion of the device and capable of translational motion, play a role of pushing a needle and a shaft, which constitute a needle module, forward. The needle and the shaft may be moved backward by a spring positioned inside the magazine.

Modular automatic hair implanter

The present disclosure relates to a hair implanter with an automatically retracting needle, and more specifically, to a hair implanter with an automatically retracting needle configured to automatically move a needle backward by a force of a spring when the needle is moved forward to a predetermined position to allow hair transplantation work to be smoothly performed.

The present invention relates to a method for manufacturing a bone graft material using 3D printing of a DLP system. The method includes (1) dispersing a powder material including calcium phosphate-based ceramics in a solvent; (2) recovering the calcium phosphate-based ceramics by removing the solvent from a solution in which the calcium phosphate-based ceramic material is dispersed in Step 1; (3) producing a photocurable resin composition by adding a binder resin including a crosslinking agent and a photoinitiator to the calcium phosphate-based ceramics obtained in Step 2; (4) performing 3D rapid prototyping on a bone graft material molded body from the composition for a bone graft material produced in Step 3 by 3D printing of a DLP system; and (5) debinding and sintering organic materials remaining in the bone graft material molded body subjected to prototyping in Step 4.

The present invention provides a follicle transfer and transplantation method based on FUE, which provides a follicle extraction punch for transferring and transplanting a follicular unit of a scalp and loads a follicular unit, extracted by the follicle extraction punch, to the follicle extraction punch itself or transfers the extracted follicular unit to a separate needle, thereby enabling a hair transplantation operation to be relatively quickly and accurately performed.

Follicle transfer and transplantation method based on follicular unit extraction

Provided is a manual follicle-transplanting hair transplanter for increasing a graft survival rate. The manual follicle-transplanting hair transplanter includes a needle member having a lower end containing a follicle to be transplanted and having a head having a larger diameter than a portion below the head at an upper end thereof, a rod member inserted into the needle member and having a push portion having a larger diameter than a portion below the push portion at an upper end thereof, an inner body configured to contain the needle member and limit downward movement of the needle member, and an outer body configured to contain the inner body and limit upward movement of the needle member. The needle member is automatically withdrawn when a compressed spring disposed in the inner body expands and pushes up a lower surface of the head.

Manual follicle-transplanting hair transplanter for increasing graft survival rate

Provided is an automatic hair transplanter for transplanting follicles including a housing having a space therein and having an aperture in a front surface, a cartridge installed behind the aperture and having a plurality of holes containing each of needle and rod assemblies, a cartridge driver configured to sequentially cause centers of the needle and rod assemblies to correspond to the center of the aperture by causing the cartridge to make a rectilinear motion or a rotary motion, a needle-and-rod assembly pressurizer configured to pressurize the back end of a needle and rod assembly whose center corresponds to the center of the aperture, and a manipulator having a switch for controlling operations of the cartridge mover and the needle-and-rod assembly pressurizer.

Automatic hair transplanter for transplanting follicles

Disclosed are an apparatus and a method for controlling a room lamp of a vehicle. The present invention relates to collecting information associated with the vehicle and information associated with an ambient environment using a global positioning system (GPS) or a controller area network (CAN) and then controlling the room lamp using at least one of turn-off of the room lamp, change of an irradiation angle of the room lamp, and adjustment of illumination of the room lamp based on the collected information.

Apparatus and method for controlling room lamp of vehicle

Provided is a method for mobile sensor node roaming in an environment of first and second adjacent wireless sensor networks having a plurality of sensor nodes. The method includes the steps of: periodically performing energy detection scan and active scan operations, at the mobile sensor node forming an association with a parent node of the first wireless network, and obtaining energy values of selected channels and link quality indications (LQIs) for the channels; when the sensor node moves to the second wireless sensor network, periodically performing energy detection scan and active scan operations, at the sensor node, and obtaining energy values of selected channels and link quality indications (LQIs) for the channels after movement; comparing, at the sensor node, the energy values and link quality indications (LQIs) of the selected channels before and after movement.
