Real-Time Fall Risk Detection

P.A.L.S. uses RPLIDAR C1 sensors to continuously map your living environment. When a pet enters a zone where an older adult is present or moving, the system calculates fall risk in real time — and alerts caregivers instantly.

Every room is unique. P.A.L.S. learns the spatial layout of the home and identifies which zones — stairs, kitchens, nighttime pathways — present the highest co-presence risk.

  • 360° continuous LiDAR sweep, updated 10× per second
  • 🐾
    Distinguishes pets from humans — no false alarms from furniture or shadows
  • 📱
    Instant push alerts to caregivers via mobile app and Alexa voice notification
  • 🔒
    All data processed locally — privacy-first architecture, nothing stored in cloud

01 📡
LiDAR Sensing Layer
RPLIDAR C1 · UART

Rotating LiDAR sensors mounted discreetly in each room capture full 360° point-cloud data, detecting objects as small as a household cat with centimeter accuracy.

02
Edge Processing
ESP32 · ESP-NOW Protocol

Ultra-low-latency ESP32 microcontrollers process spatial data at the edge, communicating wirelessly via ESP-NOW to the master base station — no WiFi required for core detection.

03 🧠
AI Risk Classification
AWS Lambda · Custom ML

A machine learning model trained on fall-incident patterns classifies co-presence risk in real time. Context-aware: nighttime and high-traffic zones receive heightened sensitivity.

04 🗣️
Voice Integration
Alexa Skill · "Pet Aware"

The certified "Pet Aware" Alexa Skill delivers natural-language alerts and daily summaries. Families can ask Alexa for status updates or configure alert thresholds using voice commands.

05 📲
Caregiver Alerts
Push Notifications · Mobile

Designated family members and professional caregivers receive instant push alerts when high-risk co-presence is detected — with room location and contextual risk data included.

06 🔐
Privacy-First Design
No Cameras · No Audio

P.A.L.S. uses only LiDAR point-cloud data — never cameras or microphones for spatial sensing. No identifiable information is stored. Dignity is not optional; it is engineered in.

From Sensor to Safety

"The presence of a beloved pet should bring joy, not risk. P.A.L.S. exists so that no older adult ever has to choose between the companionship of their animal and their own safety."

— Dr. Melissa Mansfield, PhD, NAPG-C · Founder, The Gerontechnology Group

Alexa, is Frida
in the kitchen?

The "Pet Aware" Alexa Skill makes P.A.L.S. conversational — designed for older adults who prefer speaking over tapping. No app needed, no learning curve.

User "Alexa, ask Pet Aware where Frida is."
Alexa "Frida was last detected near the kitchen entrance. Your fall risk in that zone is currently moderate. Would you like me to alert your caregiver?"
User "Yes, please notify Maria."
Alexa "Done. Maria has been notified and will receive a full sensor report. Stay safe — I'm always watching for Frida."
