Next-Generation Child Presence Detection (CPD) Target — Now Upgraded
Building on a proven high-fidelity CPD target platform, the latest generation introduces enhanced sensory interaction and automation, enabling more comprehensive and efficient in-vehicle child detection testing.
Newly Added Capabilities
1. Eye-Gaze & Visual Interaction Control
Supports controllable eye and gaze behaviors, enabling richer and more realistic visual-based detection scenarios for camera and vision-fusion systems.
2. Acoustic Simulation
Integrated sound playback allows simulation of infant/child crying, distress calls, and help-seeking sounds, supporting audio-based and multi-modal sensing strategies.
3. Multi-Task Automated Execution
- Supports
up to 30 automated tasks in a single test sequence
- Single-task duration adjustable from
10 seconds to 18 hours
- Enables long-duration, unattended testing and significantly improves test efficiency and repeatability
Core Capabilities (Existing Platform Features)
1. High-Fidelity Vital Sign Simulation
- Realistic simulation of
child breathing and heartbeat with high temporal accuracy
- Multiple breathing patterns supported, including:
- Rapid breathing (awake / emotional states)
- Slow breathing (deep sleep)
- Irregular breathing and apnea-like abnormal sequences
- Micro-Doppler waveforms and spectral characteristics
closely match those of real children, optimized for millimeter-wave and radar-based detection
2. Radar Cross Section (RCS) Matching
- Scattering characteristics designed to closely replicate real child body responses across multiple frequency bands (e.g.,
9GHz / 24GHz / 60 GHz / 77GHz/ 140 GHz mmWave)
- 360-degree incidence angle calibration
, supporting radar detection from all in-cabin directions
3. Multi-Joint Behavioral & Posture Simulation
- Approximately
14 degrees of freedom, using modular actuators
- Supports limb motion, natural body movement, and posture variation for realistic behavioral modeling
4. Age-Specific Anthropometric Fidelity
- Covers four high-risk age groups:
0, 1, 3, and 6 years
- Body dimensions aligned with child anthropometric statistics, facilitating algorithm tuning and validation across representative age profiles
5. Broad Multi-Sensor Compatibility
Compatible with a wide range of in-vehicle sensing technologies, including:
- Millimeter-wave radar (60 GHz / 140 GHz)
- 4D imaging radar
- Ultra-Wideband (UWB)
- Wi-Fi sensing (e.g., 5.8 GHz)
- Vision systems (RGB cameras, infrared / low-light / night-vision)
