Active Signal Technologies was founded in 1996 by members of Lockheed Martin’s advanced sensor and solid-state actuator group, carrying that research background into specialized device development. The Maryland company’s work is especially associated with the Brain Acoustic Monitor, a portable system developed for noninvasive assessment of traumatic brain injury in military, hospital, and emergency-care settings. It also developed a noise-immune stethoscope for clinicians working in aircraft and other extremely loud environments.
