Appeal No. 2001-1795 Application 08/825,196 invention is that the convergence angle of the ocular devices is fixed as a function of working distance which provides a highly stable configuration, resistant to vibration or impact and misadjustment during use. Representative claim 1 is reproduced as follows: 1. An ocular mounting assembly, comprising: an ocular support assembly providing interpupillary distance adjustment for a pair of ocular devices attached to the support assembly, each ocular device being initially rotatable with respect to the support assembly at respective regions of rotation, the relative rotation between the pair of oculars establishing a convergence angle; means for independently and permanently preventing the rotation of each ocular with respect to the support assembly at respective regions of rotation once a desired convergence angle has been achieved; and an adjustable clamp assembly rotatably attached to the ocular support assembly providing height and view angle adjustment of the ocular devices and allowing the ocular devices to be flipped up out of the way when not needed.
