- Prototype development spanned over a year, indicating the speaker's dedication and perseverance despite initial setbacks.
- Facing skepticism from peers, including laughter and advice to concentrate solely on medical practice, the speaker remained committed to their goal of helping others through innovation.
- The speaker's childhood aspiration to impact many lives as a doctor was a driving force behind their determination to overcome challenges in medical device creation.
6. 🧠 Learning from Curiosity: Embracing 'Grand Waste'
- The philosophy of 'grand waste' posits that while small waste remains waste, grand waste can transform into something valuable, encouraging the pursuit of curiosity and diverse interests.
- The speaker recounted personal experiences of losing track of time during spontaneous activities, such as traveling or taking time off for focused study, showcasing deep engagement in curiosity-driven pursuits.
- Despite being the sole employee for the first two years of founding a company, the speaker iterated on different prototypes using a 3D printer, highlighting a relentless pursuit of innovation.
- Technical challenges were a constant, with sensor adjustments affecting sound quality and changes in preamps or power amps altering frequency characteristics, illustrating the complexity of product development.
- Financial constraints were significant, requiring the speaker to personally seek funding from investors nationwide due to high patent and development costs, demonstrating resilience and resourcefulness.
- Security challenges arose while transporting prototypes during air travel, with equipment often flagged as potential security threats, adding to the logistical hurdles.
- Even when prototypes failed during investor demonstrations, the speaker's ability to communicate a shared vision helped secure investment, emphasizing the importance of vision and communication skills.
- The journey involved trial and error and numerous improvements, supported by a community of people, highlighting the collaborative nature of innovation and success.
7. 🔬 Research Focus: Heart Sounds and Beyond
- The research focuses on three themes: temple sounds, sound quality, and visualization.
- Temple sounds are studied alongside heart sounds to enhance understanding through AI learning, involving simultaneous acquisition, storage, and playback.
- Sound quality research emphasizes capturing the low and soft heart sounds within the human audible range of 20Hz to 2000Hz, aiming for improved accuracy.
- The technology has received approval from the Ministry of Health, Labour and Welfare, highlighting its advanced frequency characteristics.
- Sound quality improvements are crucial for precise heart sound capture and analysis.
8. 🔍 Visualizing Heartbeats: Technology Meets Tradition
- A palm-sized device wirelessly connects to a PC to capture heart data, providing an 8-second waveform report post-examination.
- AI estimates severity and risk levels using alphabetic characters and numerical probabilities, allowing for quick assessment.
