1Speed
If Bluetooth BR/EDR protocol is used for data transfer, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between Bluetooth BR/EDR and BLE protocols based on real-time conditions including device state, sensor data, and remote device characteristics. This dynamic adaptation allows the system to optimize the trade-off between transmission speed and power consumption by selecting the appropriate protocol for each specific situation.
Solution Approach 2:
The invention changes the operational parameters by selecting different Bluetooth protocols (BR/EDR or BLE) based on varying conditions such as battery level, motion state, and data type. This parameter change enables the system to adjust its transmission characteristics to match current operational requirements.
2Use of energy by moving object
If adaptive protocol selection is implemented, then power efficiency is improved, but device complexity increases
Solution Approach 1:
The biometric monitoring device is designed with multi-functionality by incorporating both Bluetooth BR/EDR and BLE interfaces, along with various sensors (motion, light, proximity) that can serve multiple purposes. This universal design allows the device to adapt to different conditions and optimize power efficiency without requiring separate specialized devices.
Solution Approach 2:
The system uses feedback from multiple sensors (accelerometer, gyroscope, light sensor, proximity sensor) to continuously monitor device state and environmental conditions. This feedback is processed to determine the optimal Bluetooth protocol for data transfer, enabling adaptive power efficiency management based on real-time device state.
3Adaptability or versatility
If multiple Bluetooth interfaces are used, then communication versatility is improved, but device complexity increases
