Abstract: Proposed are a gait measurement system and method using a LiDAR adjacent to a floor. More specifically, the system includes a walking path for a measurement subject to walk, a LiDAR sensor device installed on the floor at a side of the walking path and configured to scan the walking path, and a gait analysis part configured to use a signal detected by the LiDAR sensor device to analyze a gait of the measurement subject walking on the walking path. The method includes collecting scanning data obtained by the LiDAR sensor device scanning the walking path on which the measurement subject is walking, analyzing the scanning data to specify foot positions of the measurement subject, and using the specified foot positions of the measurement subject to analyze at least one selected from a group of step length, the number of steps, and gait speed, from changes in the foot positions.

Abstract: Provided is a patient monitoring system using recognition of a code, the system including: a patient measurement device configured to measure vital information of a patient, and generate measurement data as the code and display the code; a user terminal configured to recognize the code displayed on the patient measurement device, and transmit the measurement data obtained through the recognition of the code to a server; and the server configured to collect and store the vital information of the patient collected by the patient measurement device, and monitor the vital information to provide monitoring data to the user terminal.

Abstract: A multi-channel pulse oximeter system is proposed. The system includes a measurement part for measuring PPG signals in a light transmission method in six places on a human body, including both earlobes, both fingers, and both feet, an analysis part for comparatively analyzing the six PPG signals measured by the measurement part, and a result provision part for providing analysis results of the analysis part, wherein the measurement part is configured to include first and second measurement parts respectively mounted on both of the earlobes of the human body, third and fourth measurement parts respectively mounted on a distal end of any one of left fingers and a distal end of any one of right fingers of the human body, and fifth and sixth measurement parts respectively mounted on a left toe and a right toe of the human body, the first to sixth measurement parts measuring the PPG signals.
