1. Hardware & Physical Specifications
Engineered for 24/7 wearability, removing the friction of daily charging. We utilize industrial-grade components to ensure reliability in care environments.
Sensors: We utilize distinct sensor suites, including a Multi-axis Accelerometer, Gyroscope, and Optical Heart Rate (PPG) sensor.
Battery Life:
Ring: Up to 15 days between charges.
Wristband: 30+ days between charges.
Testing Condition: These estimates are based on a "Low-power monitoring mode" profile, assuming 24/7 wear with optimized data packet syncing. Actual battery life may vary based on alert frequency.
Water Resistance: Rated IP68. The device is sealed against dust and water, making it suitable for showering and bathing—critical areas where high-risk slips often occur.
Materials: The outer shell materials will be designed to minimize skin irritation during long-term wear.
Form Factor: The device features no screen. This is a deliberate design choice to maximize durability, extend battery life, and reduce the "cognitive load" often associated with smartwatches.
2. Connectivity & Infrastructure
Reliability where standard Wi-Fi fails. Care environments often present connectivity challenges, including thick walls (historic buildings) and complex layouts. The Haelo network is designed to overcome these challenges.
Redundancy: The system will be designed to include automatic Cellular Backhaul Redundancy. If the facility's internet connection fails, the hub switches to 4G/5G to keep the safety net active.
Coverage Validation: All B2B/Care Home installations undergo site-map validation to ensure coverage across complex layouts using unlimited hubs where necessary.
3. Predictive Analytics & Algorithms
Moving from generic thresholds to individual baselines. Haelo uses "Edge Computing" to process data on-device. This allows us to filter false alarms and preserve battery life before signals are sent to the cloud.
How We Establish Your Baseline
Falls often do not happen in isolation; they are preceded by subtle changes in health. We move beyond generic "thresholds" by building a personalized safety profile for every wearer.
Onboarding: We utilize a detailed questionnaire to establish an initial risk profile based on mobility and medical history.
The Learning Phase: Over the first 2–4 weeks of wear, the system collects sufficient data to build a completely distinct, personal user baseline.
Spotting Deterioration
Once a baseline is set, our algorithms monitor for specific deviations that may indicate a higher risk of falling or illness, utilizing:
Physiological metrics: Deviations in Resting Heart Rate (RHR) and Skin Temperature.
Behavioral metrics: Significant drops in daily activity levels or signs of lethargy.
Fall Detection Logic
Our AI models are trained to distinguish between "everyday gestures" (clapping, sitting down heavily) and genuine fall impacts.
Validation Status: Our algorithms are being developed in partnership with research labs to refine sensitivity and specificity.
4. Behavioral & Routine Analysis
Contextual safety beyond the fall.
Location Tracking: Utilizing the Bluetooth Mesh network, the system creates a digital map of the facility to assist staff in locating residents quickly.
Isolation & Wandering: The system analyzes step counts and location dwell-time to flag "unusually long periods in a room" or "wandering at night," which may signal cognitive decline or distress.
5. Validation Progress Log
Current pilot and research progress:
Current Status: Pilot Validation Underway.
Research Partners: We are collaborating with the University of Bath to validate our sensor data against clinical standards.
Real-World Testing: We are running pilots with Burleigh House Care Home to validate hardware durability and comfort in live care scenarios.
6. Privacy & Ethical Design
Safety without surveillance.
Hardware Privacy: The device contains no cameras and no microphones. It is physically impossible for Haelo to record audio or video.
Data Privacy: Sensor data is translated into "Abstract Signals" (e.g., "Impact Detected," "Motion: Normal") rather than raw intrusive feeds.
Encryption: All user data is encrypted in transit and at rest, adhering to best-practice data encryption principles.
7. Regulatory & Compliance
Security and standards roadmap.
Data Privacy: Our data architecture follows the principles of GDPR and UK GDPR, prioritizing user sovereignty and data minimization.
US Standards: We are developing our security protocols to support HIPAA alignment for future US healthcare partners.
Hardware Certification: Our hardware development roadmap targets full UK CA and CE compliance prior to commercial launch.
8. Comparative Methodology
How we calculate our comparisons. When comparing Haelo to other devices on our website, we use the following methodology and sources:
Vs. Apple Watch: Battery life claims (~18 hours) are based on official Apple Technical Specifications. We reference "Cognitive Load" regarding touchscreens as a barrier to entry for users with cognitive decline.
Vs. Traditional Pendants:
Abandonment Rates: The claim that "75% of users abandon pendants" is based on NIH/PMC studies regarding stigma and discomfort.
The "Long Lie": The statistic that "80% of seniors who remain on the floor for >1 hour did not use their alarm" is cited from BMJ (Fleming & Brayne).
Unwitnessed Falls: The claim that "60–80% of falls in care are unwitnessed" is based on research published in BMC Geriatrics.
9. Limitations (Safety Notice)
What Haelo does (and doesn't) do. No safety technology is 100% infallible.
Detection Probability: While we strive for high accuracy, automated systems cannot detect 100% of falls, particularly "soft falls" (e.g., sliding from a chair) which lack distinct impact patterns.
Connectivity: The device requires a functional connection to the Haelo Hub infrastructure to transmit alerts.
