What This Patent Covers

This patent protects a method, device, and program for high-precision alertness estimation, specifically covering the combined use of deep learning for frame-by-frame and time-series image analysis, and ensemble learning for comprehensive estimation. The claims are robust, having successfully overcome a rejection notice and demonstrating strong patentability against nine prior art documents, ensuring a stable foundation for licensees to prevent imitation and secure long-term technological advantage.

Competitive White Space

This patent primarily covers visual-based alertness estimation. White space exists in integrating non-visual biometric data (e.g., heart rate, brainwave activity) for multi-modal alertness assessment, or developing predictive analytics for long-term fatigue management and personalized intervention strategies.

Economic Impact
~$150K/year (AI est.) in accident-related cost reduction per facility (est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

Implementing this technology could reduce dozing-off accident rates in the transportation industry by an estimated 5%. Assuming an average damage cost of ~$350K (AI est.) per accident (including material damage, personnel costs, and reputational loss), a company experiencing 10 accidents annually could achieve (~$350K (AI est.)/accident × 10 accidents) × 5% = ~$150K/year (AI est.) in cost savings. This represents a direct economic benefit from enhanced safety management and contributes to increased corporate value.
