Abstract: A multispectral illumination device includes a main housing configured to be secured to a helmet and an illuminator head comprising a plurality of light sources, the plurality of light sources operable to emit light in multiple spectral regions. A selector is located on the main housing for actuating one or more of the light sources within the plurality of light sources that emit light in a selected one of the multiple spectral regions. A stalk passes through an opening in the main housing and has a first end coupled to the illuminator head and a second end opposite the first end received within the main housing. The stalk is slidable within the opening in the main housing to extend and retract the illuminator head toward and away from the housing, the stalk being slidable between a fully extended position and a fully retracted position.

Abstract: A battery pack receiver assembly for detachably securing a battery pack to a helmet mounted device comprises a frame comprising a first battery pack engaging feature for engaging the battery pack. An interface plate comprises a second battery pack engaging feature. The frame is slidably coupled to the interface plate and movable between battery pack retaining and releasing positions. A biasing member is configured to bias the frame toward the battery pack retaining position. The frame is manually movable to the battery pack releasing position by a user grasping the battery pack. The second battery pack engaging feature is configured to positively retain the battery pack when the frame is in the battery pack retaining position and disengage with the battery pack when the frame is in the battery pack releasing position. Preferably, the apparatus is configured to permit one-handed battery pack replacement without removing the device from the helmet.

Abstract: A headset mounting system comprises a side shroud configured to be attached to a side of a helmet, the side shroud including a mounting receptacle. A headset assembly has a mounting plug which is configured to be detachably coupled to the mounting receptacle. The mounting plug comprises a cylindrical stub having one or more lugs. A retaining collar is disposed within the mounting receptacle and has one or more slots formed therein. At least a portion of the mounting plug is configured to fit within the collar of the receptacle when the one or more lugs are aligned with the one or more slots. The plug is configured to be rotated within the collar so that the one or more lugs engage behind the collar to secure the plug within the receptacle. In a further aspect, a headset mounting interface is provided.
