생체 신호 모니터 및
혈압 예측 시스템
Customer : ETRI
Software : LabVIEW, Python
Hardware : NIBP(Non-Invasive Blood Pressure)
AD Instruments, Attachable Bio-signal Patch(ECG, BCG, Temp, Gyro, Acc)
Description
This system measures real-time ECG (electrocardiogram),
BCG (cardiotocography), and body temperature data using
an attachable bio-signal patch. and measures blood
pressure noninvasively using NIBP (noninvasive blood
pressure). The time difference between the R peak of the
ECG and the J peak of the BCG (R-J interval) is analyzed to
derive a prediction equation. In the future, machine
learning models will be integrated to improve the
prediction accuracy.

simple defect in the solenoid valve controller but also infers and diagnoses the type of product defect
Hall Thruster
Test System
Customer : KARI
Software : LabVIEW
Hardware
- NI PXIe System (PXIe-4300, PXIe-4310)
- Power Supply (ODA, Magna, Matusada)
Description
Hall thruster test evaluate the performance of Hall Effect
Thrusters (HET), which accelerate ions using electric and
magnetic fields.
These tests verify that the HET delivers the required thrust and efficiency for spacecraft propulsion by precisely measuring thrust, electrical characteristics, and plasma conditions.
This software controls multiple power supplies (Anode, Coils, HC Heater,Keeper) in precise sequences and uses NI PXIe system for accurate voltage and current measurement, optimizing efficiency, accuracy, and safety in propulsion testing.
