Adaptive Step Count Measurement Using Dynamic Acceleration Thresholds

The patent applies dynamics by making the threshold value adaptive rather than fixed. The threshold determination unit dynamically adjusts the threshold based on detected acceleration characteristics (local maximum/minimum values) to match different movement states. This resolves the contradiction by allowing the system to maintain low complexity through automatic adaptation while achieving high measurement precision for both walking and running through state-specific threshold selection.

The patent changes the threshold parameter based on detected acceleration patterns. By monitoring local maximum and minimum acceleration values, the system identifies movement state characteristics and adjusts the threshold parameter accordingly. This parameter adaptation enables accurate step detection across different activities without requiring complex manual configuration, resolving the trade-off between simplicity and precision.

The system performs self-service by automatically determining appropriate threshold values without external intervention. The threshold determination unit autonomously analyzes acceleration data, identifies movement states through local extremum detection, and selects suitable thresholds. This self-adjusting mechanism achieves high measurement precision for different activities while maintaining operational simplicity, as the system handles the complexity internally without requiring user input or complex external control.

The patent implements feedback by continuously monitoring acceleration characteristics and using this information to adjust threshold values. The local maximum/minimum detection provides feedback about movement state, which feeds back to the threshold determination unit to select appropriate thresholds. This closed-loop approach enables accurate adaptation to different movement states while keeping the system relatively simple through automated feedback-driven adjustment.

The system maintains ease of operation while improving reliability through self-service automation. The threshold determination unit automatically adapts thresholds to match detected movement states without requiring user intervention or configuration. Users simply wear the device and move naturally, while the system autonomously adjusts parameters to ensure reliable step detection whether walking, running, or transitioning between activities.

The patent applies dynamics by making the threshold system adaptive rather than static. The threshold automatically changes based on real-time acceleration characteristics detected during different activities. This dynamic adaptation maintains operational simplicity for users while significantly improving measurement reliability across diverse movement patterns, as the system continuously optimizes thresholds to match current activity state.
