A helmet mounted display (HMD) system comprising a display pod having a light wave optical element. The display pod is designed to be attached to a base plate located above the brow of a helmet using opposing hook and loop-style fastener pads or alternatively, a pair of locking disks. The mounting position of the display pod is adjustable within three degrees of freedom, including lateral positioning along a plane that is co-planar to a mounting surface for the display pod, as well as rotation about an axis that is perpendicular to the mounting surface. The HMD system is adapted to compensate for variations in mounting position using a bore sighting adjustment.

Apparatus and method for mounting and calibrating a helmet-mounted display

Embodiments of methods, devices and systems are presented for communicating information in an explosive environment. An explosion proof video and data communication module includes features that prevent the generation of a spark or other ignition sources that could ignite explosive dust, gas or vapors in the air. The explosion proof video and communications relay modules may operate independently or as a group to provide real-time information, situation awareness, functionally and responsiveness for personnel that are in explosive environments.

Method and system for providing explosion proof video and communication relay module

A helmet that can comprise a helmet body comprising an energy absorption layer and an outer shell, A first opening can be formed through the outer shell and extend into the energy absorbing layer, the first opening comprising a perimeter. A first sleeve can be disposed at least partially within the first opening, the first sleeve comprising a first end comprising a first flange coupled to the outer shell and extending beyond the perimeter of the first opening, and a second end opposite the first end comprising a base disposed over the energy absorption layer, A camera can be coupled to the first sleeve and exposed through the first opening. The helmet can further comprise the first sleeve comprising a depth greater than a width or a length. The first flange can be directly coupled to an outer surface or an inner of the outer shell.

Helmet with integrated electronic components

A head-mounted navigation system may include an image sensor configured to sense one or more objects forward of a person and to generate image information representative of the one or more objects. A bearing sensor may be included and configured to detect bearing and to generate bearing information representative of the bearing. Securing apparatus may be included and configured to secure the bearing sensor to the person. The securing apparatus may be configured to secure the bearing sensor to the torso of the person, such as to his or her back. A processing system may be included and configured to receive the image information and/or the bearing information and to generate display information representative of the one or more objects and/or the bearing. A display may be included and configured to receive the display information and to display visual information representative of the one or more objects and/or the bearing. Head gear may be included and configured to mount on the head of the person and to position the display along a sight path of the person.

Head-Mounted Navigation System

The invention provides a system and process in which more than only one category of information must be made available in an optically simultaneously recognizable form to a person in a portable system (17) for protecting and/or guiding persons in dangerous situations, firefighters or rescue teams in buildings. The system includes an infrared camera (12) for recording data, especially heat image data; an energy supply device, especially a battery; at least one interface (18) for transmitting data; and at least one display device (16), especially a monitor and/or a warning light, for visually displaying data. At least one exit finder (13) and/or at least one gas sensor (14) and/or at least one motion detector is also provided. The data determined by the at least one exit finder (13) and/or by the at least one gas sensor (14) and/or by the at least one motion detector and the heat image data of the infrared camera (12) can be displayed on the display of the at least one display device (16) such that the visually displayed data and visually displayed heat image data are visible by the person within a field of vision.

System for protecting and/or guiding persons in dangerous situations

An abnormality detection support device, suitable for a case where rescue operations are made under situations that visibility is disturbed by smoke due to fire, includes an infrared camera, a display which, at least when the infrared camera is in use, comes to be positioned in front of a user's eyes and reproduces an image taken by the infrared camera thereon and a face protector or a helmet, on which the infrared camera and the display are provided, and the infrared camera and the display are arranged to be within an outline of the user's head in a front view when the device is put on the user. The present invention can, therefore, provide the abnormality detection support device which enables an operator to work with both hands available while directly watching the infrared image even under a circumstance that smoke or the like due to occurrence of fire disturbs the field of vision of the operator, and has excellent usability.
