Smart Archery Bow Sensor Fusion for Real-Time Shot Learning

The smart bow system is divided into separate functional modules: accelerometer module for measuring linear acceleration, gyroscope module for measuring angular velocity, processing circuitry module for data analysis, and user interface module for feedback. Each module operates independently but communicates through standardized interfaces, allowing the complex system to be managed through modular architecture.

The integrated sensor system serves multiple functions simultaneously: it monitors drawing action, detects shot release, measures bow orientation, tracks vibration characteristics, and provides real-time feedback. This multi-functionality consolidates what would otherwise require separate systems into a single unified platform, improving measurement capabilities while managing complexity through shared hardware resources.

The processing circuitry operates in periodic cycles rather than continuously. It samples sensor data at specific intervals during drawing and release phases, performs analysis only when needed (e.g., when shot completion is detected), and enters low-power states during idle periods. This periodic operation maintains reliable skill monitoring while significantly reducing average power consumption compared to continuous processing.

The system automatically detects when processing is needed based on sensor threshold crossings (such as detecting when the bow has completed its draw cycle or when release occurs). This self-triggered operation eliminates the need for continuous monitoring and allows the processing circuitry to remain dormant until actual archery actions occur, optimizing the balance between reliability and power consumption.
