What This Patent Covers

This patent protects a haptic measurement device that uses dorsally-mounted vibrators and sensors to detect subtle finger vibrations upon contact, enabling high-precision acquisition of contact object information without obstructing natural fingerpad sensation. The rights are robust, having overcome examiner objections during prosecution, and broadly cover various application scopes and constituent elements of the technology.

Competitive White Space

While this patent broadly covers the haptic measurement device, white space exists in advanced AI-driven interpretation of the haptic data, integration with specific robotic end-effectors beyond finger mounting, and novel haptic feedback output systems that complement the input for a full closed-loop haptic experience.

ROI Calculation Logic

Assuming 5 skilled operators spend approximately 4,000 hours annually on quality inspection per manufacturing line, this technology could reduce inspection time by 25%. This translates to an estimated 1,000 hours/year (equivalent to ~1.5 full-time employees) in labor savings, valued at ~$80K/year (AI est.) in personnel costs. Factoring in reduced defect rates from improved quality, the total economic impact could exceed ~$150K/year (AI est.).
