[2023-10] CareNurse N1

Note: To protect commercial confidentiality, public information is limited.

Project Overview

CareNurse N1 is an integrated homecare solution for Amyotrophic Lateral Sclerosis(ALS, 渐冻症) patients, combining hardware terminals, cloud services, and mobile applications.

Key technical breakthroughs:

  • NIR facial detection under extreme head orientations (yaw>75°, pitch>35°, roll ±180°) with striped non-uniform lighting (caused by dual-frequency eye tracker illumination)
  • 98-point facial landmark localization based on the above scenario
  • Far-infrared body temperature measurement
  • Contactless NIR-based respiratory/heart rate monitoring

Since August 2021, we’ve progressed from concept to market-ready product through:

  • 4 proof-of-concept iterations
  • Deployment in 100+ households
  • Three PR campaigns generating 10M+ media impressions
  • Multiple international awards

Most significantly, our system has saved lives by enabling emergency alerts when patients experience suffocation episodes – a critical need given their inability to move or speak during such crises.

Roles & Achievements

Joined during the foundational phase with multi-faceted contributions:

  • Built audio event recognition system for alert triggering

Product Design

  • Spearheaded functional prototyping and hardware architecture
  • Directed UED for mobile applications

Operations

  • Owned user acquisition campaigns and partnership development with NGOs
  • Led key event planning and PR outreach

Secondary Roles
Project Management

  • Managed requirements scoping and development timelines
  • Ensured milestone deliverables

QA Engineering

  • Authored test cases and drove issue resolution cycles
