  • Video headlight and cable
    Patent number: 6120161
    Abstract: A video headlight and fiberoptic cable which includes a light and camera assembly adjustably mounted on a headband for assuming a plurality of angular positions relative to the headband. The light and camera assembly includes a light unit closely positioned relative to a video camera unit so that the visual field of the camera unit lies within the lighted field from the light unit in all adjusted positions of the light and camera assembly. The light unit is connected to the forward end of the fiberoptic cable. The rearward end of the fiberoptic cable is connectable to a source of light. The one end of the fiberoptic cable has a flexible, but non-collapsible coupler which bends uniformly when the light and camera assembly is moved relative to the headband.
