Abstract: A life boat is disclosed having a hull, a propulsion system, and a conning system. The hull has an open or openable bow, a fore deck and a powered recovery ramp installed in or on the fore deck for deployment forwards of the bow for recovery of a casualty ahead of the bow of the life boat. The life boat may be unmanned and able to draw a survivor up on the recovery ramp and into the relative safety of the rescue deck area of the fore deck without human assistance. The life boat 1 may include a cabin area where the survivor can be given more protection from the environment.

Abstract: A binocular scanning laser ophthalmoscope (SLO) is used to track the fixational eye movement of each of the eyes of a subject. The binocular SLO may include right eye optics for imaging a portion of the retina of the right eye and left eye optics for imaging a portion of the retina of the left eye. Shifts in the imaged portion of the retina with respect to a reference image of the retina may be used to measure and track eye movement. The right eye optics and left eye optics may be separate imaging paths, each with its own bi-directional MEMS scanning mirror and Keplerian telescope. The use of the MEMS scanning mirrors minimizes the size and weight of the binocular SLO.
