Heartbeat Signal Delay Mixing for Continuous Light and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to effectively express and transmit the feeling of heart beating using heartbeat signals such as heartbeat sound, electrocardiogram, and pulse wave, as direct conversion into optical or vibration signals results in instantaneous pulses, making it difficult to convey the sensation of heart beating.
Innovation Solution
A processor-based system generates a heartbeat output signal by adding delay signals to the heartbeat signal, controlling light emission or vibration, ensuring the signal is attenuated at a prescribed rate to create a continuous optical or vibration output that mimics the heart beating sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heartbeat signals are directly converted into optical or vibration signals, then the conversion process is simple and direct, but the resulting instantaneous pulses fail to express and transmit the feeling of heart beating
Solution Approach 1:
The patent applies preliminary action by generating multiple delay signals in advance before the final output. The heartbeat signal is processed to create several delayed versions (first delay signal, second delay signal, etc.) that are then combined. This preliminary processing of the signal through delay and attenuation allows the system to reconstruct a continuous heart beating sensation rather than instantaneous pulses, resolving the contradiction between simple conversion and effective sensation transmission.
2Loss of information
If multiple delay signals are generated and added to the heartbeat signal, then the feeling of heart beating is effectively transmitted, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the heartbeat signal processing into multiple distinct delay signal components. Each delay signal is generated with a specific delay time and attenuation rate, allowing the complex task of creating a continuous heart beating sensation to be broken down into manageable segments. These segmented delay signals are then systematically combined, making the complex processing task more controllable and implementable.
Solution Approach 2:
The patent employs periodic action through the use of delay signals that are generated at regular intervals and repeated periodically. The delay signals are created with specific delay times that correspond to the periodic nature of heartbeats, and they are continuously regenerated in a periodic manner. This periodic generation and combination of delay signals effectively transmits the rhythmic feeling of heart beating while maintaining a structured and manageable processing approach.
3Stability of the object's composition
If the heartbeat signal is attenuated at a prescribed rate, then a continuous optical or vibration output is created, but the energy consumption increases
Solution Approach 1:
The patent applies parameter changes by systematically varying the attenuation rate parameter across multiple delay signals. Each delay signal is assigned a different attenuation rate (first attenuation rate, second attenuation rate, etc.), creating a gradient effect that contributes to the continuous output. This parameter variation allows the system to achieve smooth, continuous optical or vibration output that mimics the natural decay and sustain of heartbeats, while the structured approach to parameter changes helps manage energy consumption through optimized signal processing.

AI summary
A heartbeat information transmission device includes a processor, and a memory including instructions that, when executed by the processor, cause the processor to perform the following processing. The processing includes: acquiring a heartbeat signal based on a heartbeat of a heart; generating a plurality of delay signals repeated for each delay time while attenuating the acquired heartbeat signal at an attenuation rate; and generating a heartbeat output signal for controlling at least one of a light emission or a vibration, the heartbeat output signal being obtained by adding the generated plurality of delay signals to the acquired heartbeat signal.
