BLE Communication Unit Block Segmentation for Power and Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) standards do not effectively support the continuous transmission of second biological information, such as calorie intake and mental stress data, which results in power consumption issues and incomplete data transmission during disconnections.
Innovation Solution
The implementation of a unique communication profile that divides data into blocks of packets, allowing for efficient transmission and reception of larger data volumes by using characteristics with properties of read with no acknowledge and write with acknowledge, enabling successful packet retransmission and communication speed adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted continuously to maintain real-time property, then data completeness is improved, but power consumption increases
Solution Approach 1:
The patent segments data transmission into periodic intervals, transmitting data in blocks at predetermined timings rather than continuously. This allows the system to maintain data completeness for second biological information by periodically sending accumulated data, while reducing power consumption by keeping the communication unit in a low-power state between transmission intervals.
2Loss of information
If data volume is increased to transmit second biological information, then information completeness is improved, but transmission time increases
Solution Approach 1:
The patent merges multiple data packets into larger data blocks for transmission. By accumulating second biological information over predetermined periods and transmitting it as consolidated blocks, the system reduces the total number of transmission events required, thereby decreasing overall transmission time while maintaining complete information transfer.
Solution Approach 2:
The system performs preliminary data accumulation and formatting before transmission. Data is collected and organized into blocks during low-power intervals, so that when transmission occurs, the data is ready to be sent efficiently in larger volumes without requiring additional processing time during the actual transmission window.
3Productivity
If communication speed is increased to reduce transmission time, then productivity is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic communication cycles where the communication unit alternates between active transmission states and low-power idle states. During active periods, data is transmitted efficiently at higher speeds to maximize productivity. During idle periods between transmissions, the communication unit enters a low-power state, reducing overall power consumption while maintaining transmission efficiency when needed.

AI summary
An information processing device includes: an information acquisition unit which acquires information; and a communication unit which communicates with an external device via near field communication. The communication unit divides data of the information into a plurality of blocks, each including a plurality of packets, transmits the plurality of blocks with a first characteristic provided with a property of read with no acknowledge, and receives a receiving result of the blocks in the external device, with a second characteristic provided with the property of write with acknowledge.
