Device for evaluating the creasing of the skin in vivo

A confocal microscope equipped with a light source, a rotary disk having holes, a highly sensitive image receiver or camera, an immersion lens, and a contact endpiece for contacting the skin and in which is engaged at least a lower part of the lens. The endpiece includes a central opening and abuts the skin about the central opening. The microscope allows for relative axial displacement of the contact endpiece relative to the lens.

Apparatus for in vivo observation of the microscopic structure of the

The process permits appreciation of variations in time of characteristics, particularly dimensions or coloration or other characteristics, of a zone of or the whole of a person. Use is made of a video camera to take an image at a given moment in time of the zone of or the whole of the person; this image is recorded in an image analyzer in order to store it; at a later time the original image is recalled and, with the aid of this recalled image, the person is placed in a position as close as possible to the position occupied when the image was made at the first moment in time, a second image is taken at the later time of the zone of or the whole of the person with the aid of the video camera, and these images are measured in the image analyzer.

Process and installation for the appreciation of variations in time of

A bayonet drive coupling comprises a barrel and end fitting to be connected by a first bayonet coupling and a spindle and sleeve to be connected by a second bayonet coupling. The second bayonet coupling comprises a slot having a straight entry portion and an oblique second slot portion to receive a pin of the spindle, whereby axial movement of the sleeve is actuated as the pin moves along the second slot portion.
