Sprint and Select Engineering Services (SES) have teamed to launch a device called AID – Automated Injury Detection - that signals first responders immediately when a law enforcement officer wearing an "officer down" vest is shot or stabbed. The AID Sensor Panel inserts into the body armor without any modification.

AID transmits an alert message that contains the officer's ID, the location of the attack shown on a map with GPS coordinates, the location of the injuries (front, back, upper chest, lower chest, upper back, lower back), as well as other medical information such as blood type and allergies. The data is sent via the Sprint cellular network to all other designated officers on the network.
