Abstract: The technology described herein relates to a vision module for a helmet mounted visual communication and navigation system. A vision module for a helmet mounted visual communication and navigation system may include a sensor directed out of a front portion of a vision module housing, a heads up display (HUD) combiner subassembly including two or more shells, a combiner glass, and a combiner mount frame, a cable connection interface, a laser configured to direct a laser beam out of a laser aperture in the front portion of the vision module housing, and one or more user control buttons. The two or more shells may be treated to minimize fogging and optical distortion for viewing of the combiner glass display. The sensors may include a thermal camera (e.g., a thermal imaging camera), a situational awareness sensor, and a biometric sensor.

Abstract: The technology described herein relates to thermal protection for a helmet mounted visual communication and navigation system. A thermal protection system may include a vision module heat sink configured to store heat dissipated from electronic components of a vision module, a compute module heat sink configured to store heat dissipated from electronic components of a compute module, and a compute module heat spreader near an electronic component of the compute module, wherein both the vision module heat sink and the compute module heat sink comprise a heat sink core at least partially filled with a phase change material. The system also may include a gasket configured to create a seal around an edge of a heat sink shell and a thermal sensor to provide data to be used to determine a remaining thermal reserve. The system also may include a cable housing configured to protect a cable from exterior heat.

Abstract: The technology described herein relates to a visual communication system for a helmet mounted visual communication and navigation system. A visual communication system may include a pointing laser on a vision module pointing forward in a direction of a user's point of view (POV), a rear communication light configured to project light in a backward direction from the user's POV, a graphical user interface (GUI) on a heads up display (HUD), and user control buttons configured to control the pointing laser, the rear communication light, and elements of the GUI. Users of such a visual communication system may include emergency response personnel and critical workers, and the GUI may display various vision modes directed to situations that may arise out of an emergency response, military, law enforcement, public safety effort or mission.

Abstract: The technology described herein relates to a balanced helmet mounted visual communication and navigation system. A helmet mounted visual communication and navigation system may include a vision module attachable to, and removable from, a front portion of a helmet by an attachment mechanism, a compute module attachable to, and removable from, a back portion of a helmet by another attachment mechanism, and a cable with an end for connecting to the vision module and another end for connecting to the compute module, the cable having a housing configured to house one or more wires. The vision module may include a sensor, a heads up display (HUD) combiner subassembly, and one or more user control buttons. The compute module may include an internal core subassembly with electronic and computing components for operation of the helmet mounted visual communication and navigation, a heat management element, and a power module.
