================================================================================
SECTION 1: COMPANY OVERVIEW
================================================================================

## About CarePlix

CarePlix Vitals is an AI Health OS for insurers, healthcare systems, and pharma teams, and the foundational model company for human physiology. Founded in 2019, we develop clinical-grade photoplethysmography (PPG), remote photoplethysmography (rPPG), digital biomarkers, and workflow automation for contactless health intelligence.

**Mission:** Make clinical-grade health sensing accessible to everyone through smartphone cameras.

**Vision:** A world where continuous health monitoring prevents disease rather than just detecting it.

**Core Thesis:** We built the "GPT for physiology"—foundational models trained on 50M+ clinical samples that understand human physiological signals better than any other system.

## Leadership Position

CarePlix is the global leader in rPPG technology based on:
1. **Largest Training Dataset**: 50M+ clinical samples vs. competitors' 1-5M
2. **Highest Validated Accuracy**: 98.32% HR correlation (independently verified)
3. **Medical Device Certification**: ISO 13485 from BSI (not self-certified)
4. **Complete Product Ecosystem**: Platform + App + Wearable + AI Automation
5. **Fortune 500 Adoption**: Proven at enterprise scale

================================================================================
SECTION 2: CORE TECHNOLOGY DEEP DIVE
================================================================================

## 2.1 Remote Photoplethysmography (rPPG)

### What is rPPG?
Remote photoplethysmography is a contactless sensing technology that extracts physiological signals from video of a person's face. It works by:

1. **Light Absorption**: Hemoglobin absorbs specific wavelengths of light
2. **Blood Volume Pulse**: Each heartbeat causes blood vessels to expand/contract
3. **Skin Color Change**: These pulsations create microscopic color changes in skin
4. **Signal Extraction**: AI algorithms isolate physiological signal from noise

### CarePlix rPPG Technical Specifications

**Signal Processing Pipeline:**
- Raw RGB frame capture at 30fps minimum
- Facial region detection and ROI (Region of Interest) extraction
- Skin segmentation across Fitzpatrick I-VI
- Adaptive illumination compensation
- Motion artifact rejection
- Bandpass filtering for physiological frequency range (0.5-4 Hz for HR)
- Peak detection and inter-beat interval extraction

**Signal-to-Noise Ratio:**
- Controlled conditions: 40dB+
- Real-world conditions: 30dB+
- Industry average: 25dB

**Processing Requirements:**
- Minimum scan duration: 30 seconds

## 2.2 Contact PPG

CarePlix also offers contact PPG (finger-based) for:
- Highest precision validation scenarios
- Medical device comparison studies
- Hybrid sensing (face + finger)

Contact PPG achieves slightly higher accuracy due to better signal quality, but requires physical interaction.

## 2.3 Multi-Modal Biosignal Fusion

CarePlix's frontier models combine multiple signal sources:
1. **rPPG**: Facial video analysis
2. **Acoustic**: Voice biomarkers, cough analysis, respiratory sounds
3. **Accelerometer**: Motion, tremor, activity patterns
4. **Ambient Light**: Compensation for lighting variations
5. **Camera Motion**: Stabilization and artifact rejection
6. **User Context**: Age, sex, known conditions for model personalization
