High Tech Night Vision And Helmet Sensors

The Gen II Helmet Sensor finally brings a screening capability to potential head and brain injuries.

When a soldier goes through a concussive event, such as an IED explosion, he or she often does not remember exactly what happened. The event is so sudden, and the jolt so intense, that there are cases where the soldier has walked away, thinking he was unharmed, only to learn later that he has suffered a traumatic brain injury.

The new Gen II Helmet Sensor takes away the guesswork by recording the forces that affected the soldier during the concussive event.

The helmet-mounted sensor records, measures and stores linear and rotational accelerations to the helmet. It even measures the overpressure generated by an explosive event. This information will help with regard to early detection of traumatic brain injury, and will help experts compile information that could lead to better detection and improved diagnosis of concussive events.

Though the unit is not a medical device, the data it collects will be very useful to the medical community in providing treatment of traumatic brain injuries.

The Gen II sensor has a USB port for charging its battery (good for one year) and for transferring its data to a laptop computer. It weighs approximately 2.14 ounces and can store up to 1 gigabyte of data.

But that’s not all!

The AN/AVS-6 Aviator’s Night Vision Imaging System (ANVIS) is a third-generation, helmet-mounted, direct-view, image-intensification device that enables aviators to operate more effectively and safely during low-light and degraded battlefield conditions.

The low-light sensitivity represents a 35 to 40 percent improvement over the earliest ANVIS. Additionally, the gated power supply enables operation at significantly higher light levels than any of the previous designs. All ANVIS systems are capable of operating for 24 hours on a pair of AA batteries.
