Abstract
According to one embodiment, a helmet is adapted to be worn on the head of a human wearer. An absorbing layer is adjacent to the helmet. The absorbing layer is configured to absorb at least a portion of a radio-frequency (RF) electromagnetic pulse. This RF electromagnetic pulse may originate from an explosion event, such as detonation of an Improvised Explosive Device (IED).
Claims16
A system for protection against traumatic brain injury, comprising:
- a helmet adapted to be worn on the head of a human wearer;
- a layer of dielectric material adjacent the helmet, the layer of dielectric material configured to absorb at least a portion of a radio-frequency (RF) electromagnetic pulse with a frequency of less than twenty gigahertz originating from an Improvised Explosive Device (IED) detonation, wherein the absorbing layer is configured to cover the ears of the human wearer;
- a visor coupled to the helmet and configured to shield the eyes of the human wearer;
- a coating adjacent to the visor, the coating configured to:
- reflect, refract, or absorb energy from the RF electromagnetic pulse away from the eyes of the human wearer, and
- reflect, refract, or absorb microwave electromagnetic energy away from the eyes of the human wearer;
- a face mask coupled to the helmet and configured to cover the jaw of the human wearer;
- and
- a second absorbing layer adjacent the face mask, the absorbing layer configured to absorb the RF electromagnetic pulse.
