Headset mounted apparatus mounting a visor with interchangeable filter sets
First Claim
1. A portable examination apparatus comprising:
- a head mountable frame;
an illumination source mounted on the frame, the illumination source configured to illuminate a tissue with radiation;
an illumination filter in operative relation with the illumination source, wherein the radiation generated by the illumination source passes through the illumination filter before illuminating the tissue;
a detector mounted on the frame, the detector configured to collect radiation emanating from the tissue illuminated with the illumination source;
a detection filter in operative relation with the detector, wherein the radiation emanating from the tissue passes through the detection filter before being collected by the detector; and
a selectably operable visor, wherein the visor includes a visor screen that incorporates the illumination filter and the detector filter.

Abstract
A portable apparatus having a source, a detector and a filtering element placed a known distance from the source and/or the detector. One embodiment of the apparatus is a headlamp having an illumination source, a camera, and two eye pieces. The headlamp has an adjustable headband for positioning the headlamp on the head of the user and a protective cover for interacting with the camera, eye pieces, and/or illumination source. The protective cover preferably includes multiple sets of filtering elements such that motion about or along an axis changes the filtering elements interacting with the camera, eye pieces, and/or the illumination source.

12. A medical examination apparatus comprising:
-
a head mountable frame; an illumination source mounted on the frame, the illumination source configured to illuminate a tissue with radiation; an illumination filter in operative relation with the illumination source, wherein the radiation generated by the illumination source passes through the illumination filter before illuminating the tissue; a detector mounted on the frame, the detector configured to collect radiation emanating from the tissue illuminated with the illumination source; a detection filter in operative relation with the detector, wherein the radiation emanating from the tissue passes through the detection filter before being collected by the detector; two eye pieces mounted on the frame, the eye pieces configured to visualize the radiation emanating from the tissue illuminated with the illumination source; a pair of eye piece filters in operative relation with the eye pieces such that the radiation emanating from the tissue passes through the eye piece filters before passing to the eye pieces; a selectably operable visor, wherein the visor includes a visor screen that incorporates multiple sets of filtering elements, each set of filtering elements includes the illumination filter, the detector filter, and two eye piece filters; and a positioning mechanism for positioning a selected set of filtering elements such that the selected illumination filter is aligned with the illumination source, the selected detector filter is aligned with the detector, and the selected eye piece filters are aligned with the eye pieces. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A portable medical examination apparatus comprising:
-
(a) a head mountable frame; (b) an illumination source mounted on the frame, the illumination source configured to illuminate a tissue with radiation; (c) a detector mounted on the frame, the detector configured to collect radiation emanating from the tissue illuminated with the illumination source; (d) a pair of eye pieces mounted on the frame, the eye pieces configured to visualize the radiation emanating from the tissue illuminated with the illumination source; (e) a visor incorporating a first and a second set of filtering elements in a visor screen, wherein each set of filtering elements includes an illumination filter, a detection filter and two eye piece filters; and (f) a mechanism for reciprocating the visor screen between a first position and a second position, wherein when the visor screen is in the first position the illumination filter of the first set of filtering elements is aligned with the illumination source such that the radiation generated by the illumination source passes through the illumination filter of the first set of filtering elements before illuminating the tissue, the detection filter of the first set of filtering elements is aligned with the detector such that the radiation emanating from the tissue passes through the detection filter of the first set of filtering elements before being collected by the detector, and the pair of eye piece filters of the first set of filtering elements is aligned with the pair of eye pieces such that the radiation emanating from the tissue passes through the pair of eye piece filters of the first set of filtering elements before passing to the eye pieces, and when the visor screen is in the second position the illumination filter of the second set of filtering elements is aligned with the illumination source such that the radiation generated by the illumination source passes through the illumination filter of the second set of filtering elements before illuminating the tissue, the detection filter of the second set of filtering elements is aligned with the detector such that the radiation emanating from the tissue passes through the detection filter of the second set of filtering elements before being collected by the detector, and the pair of eye piece filters of the second set of filtering elements is aligned with the pair of eye pieces such that the radiation emanating from the tissue passes through the pair of eye piece filters of the second set of filtering elements before passing through to the eye pieces. - View Dependent Claims (20, 21, 22, 23, 24, 25)
