A follower element flowmeter which includes a hollow enclosed toroidal path around which a follower element travels in response to a flowing fluid. A pair of sensors are located adjacent to the fluid inlet and outlet to sense the passage of the follower element. The transit times of the follower element from inlet to outlet and from outlet to inlet is determined. The internal torus is described by juxtaposed housing halves one of which contains the fluid inlet and one, the fluid outlet. The halves are constructed so as to be relatively rotatable such that the distance between the inlet and outlet may be varied to adjust the calibration of the flowmeter.

An improved, self-contained, remotely controlled color television system is disclosed. The system utilizes a small head mounted television camera which is adapted to transmit a picture of the operations carried on by the wearer of the camera to be remotely viewed and/or recorded by a third party. The focusing and aiming of the camera is remotely controlled from a console equipped with controls and a television monitor. An illumination system is provided which utilizes a dual beam, the convergence and elevation of which is controlled by the wearer. The illumination is fixed to the head mounting so as to follow the head movements of the wearer. The dual beam of the illumination system enables the area desired to be illuminated by the wearer to be so illuminated virtually without shadows and without interference to his field of view. The video image reproduced by the system is of a high quality which makes it quite useful for teaching and demonstrating such things as delicate surgical procedures of the type often found in dental, abdominal, cardiovascular and neurosurgery. Control of the illuminaton system by the wearer enables him to work without distraction caused by remote control of the illumination system. A second stationary mounted camera may be added to this system to provide additional coverage.
