As intelligent cabin systems increasingly focus on occupant monitoring and child presence detection, ivsafes has further advanced its flagship CPD (Child Presence Detection) target. Designed specifically for evaluating in-cabin sensing systems, the 2025 version of CPD introduces a major upgrade in breathing simulation technology, now featuring nine programmable breathing control modes. These enhancements enable highly realistic simulation of a wide range of physiological conditions—crucial for the validation and development of next-generation child presence detection algorithms

In contrast to the previous generation, which featured only static, fixed-pattern respiration simulation, the upgraded CPD dummies incorporates nine programmable dynamic breathing modes, enabling precise emulation of physiological variability under diverse real-world conditions:

These programmable modes allow the simulation of conditions such as restlessness, deep sleep, irregular breathing, and apnea—providing more rigorous testing scenarios for perception systems under fluctuating or low-signal conditions.

Equipped with high-precision actuators and proprietary infant physiological modeling algorithms, the upgraded CPD can generate realistic micro-movements with real-time characteristics and micro-Doppler shifts. Breathing patterns can be programmed to simulate:

: Awake or agitated state

: Deep sleep or resting state

: For robustness testing under weak signals

: Introduces natural biological variability to improve AI generalization under nonlinear conditions

The generated micro-Doppler and phase variation signals closely replicate the thoracic motion of real children.

Our proprietary control engine generates rich breathing signal sequences in real time. Each frame of output has physiological meaning, making it ideal for algorithm training, edge case analysis, and robustness verification.
