Title: Eye movement tracking system - uses IR beam and TV camera to register reflections from cornea and retina
Inventor: PERNIER JACQUES
IPC: G06T7/00
Filed: 1977-02-28
Abstract: The eye is illuminated by a beam of infrared light whose axis is colinear to the optical axis of a television camera. The reflection of the beam on the retina actuates the appearance on the camera photosensitive surface of a brilliant image of the pupil whose shape is approximately circular. The reflection of the same beam from the cornea causes the appearance on the camera photosensitive surface of an even more brilliant image, in the form of a spot of much smaller dimensions than the pupil image. The video signal produced by the camera is analysed so as to determine the position of the centre of the pupil image, and the position of the centre of the reflected corneal image. Back positions are determined with respect to the frame of the televised image so as to calculate from the positions, two components defining the position of the axis of the gaze.

Actuators ensure that the position of the coupling axis (14) of this lock socket can be temporarily blocked in relation to the door element. One of the locking elements is connected with arrangement by means of which the socket (6) is aligned with the coupling axis of the locking pin (5).
Patent FR-2361163-A1 (FR)
IPC: B05B11/00
Filed: 1977-04-26
Abstract: The device comprises a pump which has an actuating member (4) which can be pressed downwards, a two-part pump piston (5, 6) with a valve (13) mounted on the inner piston (6) and a pump cylinder (7) into which the intake line (15) for the nebuliser liquid opens out. Furthermore, a reservoir (22) closed by a valve (21) is connected to the pump cylinder (7). The liquid taken in each time the pump piston (5, 6) is raised is pressed into the reservoir (22) the next time the pump piston is moved downwards, which reservoir expands elastically counter to the effect of a spring (23). For nebulising, the actuating member (4) is moved down completely; the valve (13) on the pump piston (5, 6) opens the reservoir valve (21) and is thereby opened itself. By virtue of the spring (23), the entire reservoir contents can escape via an annular gap (8) and the spraying nozzle (10). By virtue of the reservoir (22), a multiple of the pump volume can be sprayed at one time.
