Rahm Sensor Development

High-risk events often go unnoticed when people are alone. In public safety facilities, medical distress, self-harm, and unresponsiveness can occur between routine checks. In senior living, falls and medical emergencies can go undetected in private rooms. Older adults living independently face similar risks at home. Existing solutions rely heavily on manual checks, wearable devices, or cameras that provide only part of the picture. There is a growing need for continuous, privacy-conscious monitoring that does not require individuals to wear, charge, or activate a device.

Rahm has developed an ambient monitoring platform that combines radar sensing, vision, and edge AI to continuously monitor physiology, movement, and behavior without physical contact. Our multimodal approach detects meaningful changes in human state and converts them into actionable alerts and documented events, helping staff and caregivers respond faster. The platform powers Cell-Guardian for public safety and Silver-Guardian for senior living, with future expansion into home monitoring. One technology platform serves multiple markets without requiring individuals to wear or interact with a device.

Cell-Guardian is commercially deployed across 12 public-safety facilities, with approximately 70 systems deployed and over $360K in purchase orders. The company has an immediate sales pipeline of $611K and an additional $1.74M in proposals. Silver-Guardian has entered the senior living market, with active pilot testing across two sites and six units deployed. Rahm is building on the team's previous success with VetGuardian, a non-contact vital signs monitoring platform acquired by Zomedica for $18M in 2023. Both Guardian products are supported by Rahm's patented sensing technology and ongoing FDA regulatory development.
