2BUGI-SMKJ-ISleep health monitor

manual Product Introduction Positioning and Core Technology Shenmou Technology's Carnation Smart Monitor integrates sensor technology, AI algorithms, and a health database to provide 24/7 accurate monitoring of heart rate and respiration without contact or radiation, achieving seamless health protection. Core Functions and Health Management Based on LSTM neural network analysis of HRV and sleep quality, it provides early warnings of sleep apnea and arrhythmia risks, generates weekly/monthly reports, and offers health recommendations. It models the baseline period (1-30 days), dynamic period (31-90 days), and inter- vention period (91+ days) to construct a closed loop of monitoring, early warning, intervention, and tracking. Application scenarios and differentiat- ing advantages For home-based elderly care, post-opera- tive rehabilitation, and sub-healthy individuals, high precision and privacy are ensured through multi-terminal synchro- nization; invisible monitoring is integrated into daily scenarios, practicing "invisible technology, visible health," and reshaping the standards of intelligent health moni- toring.

FCC 47CFR §2.1091 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of the human exposure to radio-frequency (RF) radiation as specified in 1.1307 (b) Limits for Maximum Permissible Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm²) Limits for Occupational / controlled Exposures 300 - 1500 -- -- F/300 3.0-30 1842/f 4.89/f *(900/f²) 1500 – 100000 -- -- 5.0 Limits for General population / Uncontrolled Exposure 300 - 1500 -- -- F/1500 1.34-30 824/f 2.19/f *(180f²) 1500 – 100000 -- -- 1.0 F= Frequency in MHz Friss Formula Friss Transmission Formula: Pd = (Pout * G) / (4*pi*r²) Where Pd = power density in mW/cm² Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = Distance between observation point and the center of radiator in cm If we know the maximum gain of the antenna and the total output power to the antenna, through calculation, we will know MPE value at distance 20cm.
