Smart Band Hydration Tracker Using Accelerometer-Based Sip Detection

The patent introduces an accelerometer as an intermediary device that indirectly measures fluid intake by detecting orientation changes and motion patterns of the bottle, rather than directly contacting the liquid. This mediator translates physical bottle handling into measurable data without requiring complex fluid sensors.

The patent replaces complex mechanical fluid contact sensors with a simpler accelerometer-based system that uses motion and orientation detection. This substitution eliminates the need for specialized liquid-contacting components while maintaining measurement capability through algorithmic analysis of bottle handling patterns.

The patent extracts the sensing function from the liquid-contacting domain and places it in the air-exposed domain. The accelerometer remains outside the liquid, mounted on the bottle exterior, eliminating degradation from liquid exposure while preserving the ability to infer consumption through motion analysis.

The accelerometer serves as an intermediary that indirectly measures consumption without contacting the liquid. It detects bottle orientation and motion patterns that correlate with drinking behavior, providing reliable data without the reliability issues of liquid-contacting sensors.

The patent creates a universal tracking system where the accelerometer and processing algorithms can be applied to any bottle or liquid container. The system detects general motion and orientation patterns that are common across different container types, making the solution adaptable to various containers without requiring specialized designs.

By replacing container-specific mechanical sensors with a general-purpose accelerometer and software algorithm, the system achieves versatility across different container types. The algorithm adapts to various bottle shapes and sizes by analyzing fundamental motion patterns rather than requiring container-specific calibration.
