OSHKOSH, Wis. – The Winnebago County Sheriff’s Office is crediting in-cell health monitoring technology with helping staff identify and respond to a serious medical emergency at the Winnebago County Jail.

On May 15, 2026, a 61-year-old man was taken into custody on a Wisconsin Department of Corrections probation and parole warrant. Due to his level of intoxication, he was first sent to a local hospital for medical clearance before being booked into the Winnebago County Jail later that afternoon. Because of his condition, he was placed alone in a single cell in the jail’s booking area – a cell equipped with video monitoring and a Reassurance Solutions ReassureSense, a contactless radar-based device that continuously monitors movement, heart rate and respiration.

Jail nursing staff checked the man’s vitals that evening and found them within normal range. Overnight, however, the Vital Sensor detected a heart rate that had dropped below a safe threshold, automatically triggering an alert and turning the cell’s status to orange on the jail’s monitoring dashboard.

Staff responding to the alert opened the cell and checked on the man, who initially said he was fine and laid back down. During that brief exchange, however, deputies noticed other areas of concern and immediately called for jail medical staff. Between the sensor alert and what staff observed in person, the man was sent for further medical evaluation. He was transported to a local hospital, where doctors determined he was experiencing severe alcohol withdrawal (a condition that can be fatal without treatment) and admitted him for several days before he was discharged.

XK-300 (ReassureSense) is part of the Reassurance Solutions monitoring platform, which uses FDA-cleared radar technology to track heart rate, respiration and movement without any physical contact with the person being monitored. The system installed in April of 2025, is designed to alert correctional staff to subtle changes in vital signs that might otherwise go unnoticed between routine checks, particularly during the hours when intoxication, withdrawal or other medical conditions are most likely to become dangerous.

Jon Lloyd, president of Reassurance Solutions, said cases like this one reflect the purpose behind the technology.

“Alcohol withdrawal is one of the most dangerous and most overlooked emergencies that happens in a booking area. It doesn’t always look like a crisis from the outside, which is exactly why continuous monitoring matters. In this case, the sensor caught a change in this man’s heart rate that staff could not have seen on their own, and that gave them the chance to step in before it became a tragedy. This is exactly the kind of outcome we built this technology to make possible, and it’s a credit to the Winnebago County Sheriff’s Office and their staff that they acted on it immediately.”
