Abstract
Abstract An apparatus for controlling the illumination of optical examination devices adapted to be connected to the distal end of a light conducting cable connected at its near end to a source of light, which apparatus permits control of illumination of the distal end of the cable. The apparatus includes a housing connected to the distal end of the cable and adapted to receive optical examination devices. A filter support mounts a plurality of filters within the housing for selective movement in and out of the path of light eminating from the distal end of the cable. The filter support is moved by operating a positioning control on the housing which is mechanically coupled to the filter support. In operation, the optical examination device is mounted to the housing which serves as a handle for it, and the illumination of the device is selected by operating the positioning control with the same hand that holds the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
An apparatus for controlling the illumination of optical examination devices adapted to be coupled to a source of light through a light conducting cable connected at its near end to said source of light, said apparatus comprising: a housing coupled to said light conducting cable at the distal end thereof; a plurality of filters; and means within said housing for mounting said filters for selective movement into and out of the path of light eminating from the distal end of said light conducting cable; positioning means mounted to said housing for movement relative thereto; and means for coupling the movement of said positioning means to said filter mounting means so that said filters can be moved in and out of said light path by moving said positioning means.
Claim 2
Independent Claim
128 words
An apparatus for controlling the illumination of optical examination devices adapted to be coupled to a source of light through a light conducting cable connected at its near end to said source of light, said apparatus comprising: a housing coupled to said light conducting cable at the distal end thereof; a plurality of filters; and means within said housing for mounting said filters for selective movement into and out of the path of light eminating from the distal end of said light conducting cable; positioning means mounted to said housing for movement relative thereto; and means for coupling the movement of said positioning means to said filter mounting means so that said filters can be moved in and out of said light path by moving said positioning means.
Claim 3
Dependent Claim
57 words
An apparatus according to claim 1 wherein said mounting means is a disc mounted for rotation about a first axis which is eccentric with respect to said light path, said disc including means about its circumference adapted to retain said filters, said filters being moved in and out of said path of light by rotating said disc.
Claim 4
Dependent Claim
70 words
The apparatus of claim 2 wherein said positioning means is a ring mounted for rotation about a second axis not aligned with said first axis, said coupling means comprising: a plurality of teeth spaced along the inner circumference of said positioning ring; and means on the circumference of said filter disc for meshing with said teeth, so that the rotation of said positioning ring is transmitted to said filter disc.
Claim 5
Dependent Claim
27 words
An apparatus in accordance with claim 3 wherein said housing is cylindrical and serves as a hand grip, said positioning ring being mounted coaxially with respect thereto.
Claim 6
Dependent Claim
40 words
The apparatus of claim 4 further comprising detent means for stopping the rotation of said filter disc in a plurality of predetermined positions, in each of which positions a different one of said filters is aligned in said light path.
