Wireless Handover Accuracy via Optical Sensor Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional short-range wireless communication systems, such as Bluetooth, face errors in determining the approach distance due to environmental factors, leading to incorrect connection handovers between devices, especially when multiple devices are nearby.
Innovation Solution
A system comprising a first and second information processing apparatus, where the first apparatus receives packets from the second and determines if an acquisition request for wireless connection information should be sent based on received radio wave intensity, and the second apparatus uses sensors to detect objects before transmitting connection information, ensuring accurate handover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the range of propagation of radio waves is enlarged to prevent errors in distance measurement, then the reliability of connection handover is improved, but the information device may identify the approach of an object in an unintended location, worsening the measurement precision
Solution Approach 1:
The patent introduces an optical sensor as an intermediary detection means to verify object approach. The optical sensor acts as a mediator between the radio wave detection and connection establishment, providing an additional layer of verification to ensure the object is genuinely approaching the intended device before allowing connection handover, thus resolving the contradiction between reliability and measurement precision
Solution Approach 2:
The system uses the information device's own optical sensor to detect object approach, making the device self-verify its proximity status. This self-service mechanism allows the device to independently confirm whether an object is genuinely approaching without relying solely on radio wave intensity, thereby maintaining both reliability and measurement precision
2Ease of operation
If Bluetooth is used to exchange connection information, then the ease of operation is improved, but the measurement precision of approach distance deteriorates due to environmental factors affecting radio wave propagation
Solution Approach 1:
The patent merges Bluetooth communication with optical sensor detection into a unified handover system. The optical sensor detection is combined with the existing Bluetooth connection exchange, creating a composite verification mechanism that maintains the ease of Bluetooth operation while adding precision through optical detection of object approach
Solution Approach 2:
The optical sensor serves as an intermediary verification layer between the Bluetooth communication and connection establishment. It mediates the handover process by confirming genuine object approach before allowing Bluetooth connection information exchange, thereby improving measurement precision without compromising the ease of operation

AI summary
In response to receiving an acquisition request for acquiring wireless connection information from an external apparatus, it is determined whether or not a sensor for detecting a nearby object has detected an object. If it is determined that the sensor has detected an object, the wireless connection information is transmitted to the external apparatus. If it is determined that the sensor has not detected an object, the wireless connection information is not transmitted to the external apparatus.
