Submersible systems (even when incorporated in a submersible vehicle), as follows, and specially designed components therefor:
(a) Automatically-controlled atmosphere-regeneration systems specially designed or modified for submersible vehicles which, in a single chemical-reaction cycle, ensure carbon dioxide removal and oxygen renewal;
(b) Systems specially designed or modified for the automated control of the motion of a submersible vehicle using navigation data and having closed-loop servo-control(s) so as to:
(1) Enable the vehicle to move within ten metres of a predetermined point in the water column;
(2) Maintain the position of the vehicle within ten metres of a predetermined point in the water column; or
(3) Maintain the position of the vehicle within ten metres while following a cable on or under the sea bed;
(c) Underwater vision systems, as follows
(1) Television systems (comprising camera, lights, monitor and signal transmission equipment) specially designed or modified for remote operation with a submersible vehicle, having a "limiting resolution", when measured in the air, more than 500 lines, using IEEE Standard 208/1960 or any equivalent standard;
Technical Note:
"Limiting resolution" in television is a measure of resolution usually expressed in terms of the maximum number of lines per picture height discriminated on a test chart.
(2) Systems specially designed or modified for remote operation with a submersible vehicle employing techniques to minimize the effects of back-scatter, such as range-gated illuminators;
(d) Remotely controlled/articulated manipulators specially designed or modified for use with submersible vehicles and having any of the following characteristics;
(1) Systems which control the manipulator using information from sensors which measure force or torque applied to an external object, distance from an external object, or tactile sense between the manipulator and an external object;
(2) Controlled by proportional master-slave techniques or by using a dedicated stored-programme computer; or
(3) Capable of exerting a force of 250 Newtons or more or a torque of 250 Newton-metres or more and using titanium based alloys or fibrous and filamentary composite materials in their structural members;
(e) Photographic cameras and associated equipment specially designed or modified for use underwater, having a film format of 35 mm or larger, and capable of any of the following:
(1) Film advancement of more than 5 frames per second;
(2) Annotating the film with data provided by a source external to the camera;
(3) Taking more than 250 full frame exposures without changing the film;
(4) Autofocusing specially designed or modified for use underwater; or
(5) Operating at depths of more than 1,000 metres;
(f) Light systems specially designed or modified for use underwater, as follows:
(1) Stroboscopic lights capable of:
(i) Light output energy of more than 150 joules per flash; or
(ii) Flash rates of more than 5 flashes per second at a light output energy of more than 10 joules per flash;
(2) Other lights and associated equipment, capable of operating at depths of more than 1,000 metres;
(For underwater "robots", see Item IL 1391).
