Title: Sighting apparatus for determining the direction of a light beam
Inventor: ALAIN BOUTIER
IPC: G01P21/02
Filed: 1989-12-21
Abstract: The apparatus preferably comprises a theodolite, a telescope (16) with an objective (11) and a target (12) coaxial with a sighting axis (V'V), rotating about an elevation axis (S'S) and an azimuthal axis (A'A). The sighting no longer relies on the subjectivity of an operator through an eyepiece, since the apparatus includes optoelectronic means (3, 4X, 4Y) which are partially fixed on the telescope and receive a spot (TA) from an incident light beam (F) for determining the coordinates (BX, BY) of the energy density centre of the spot in a reference frame (X'X, Y'Y) defined with respect to the sighting axis (V'V). The precision of the location is increased by a factor of 10 compared to the prior art and the safety for the operator is improved. The apparatus can be used for lining laser beams in a three-dimensional laser velocimeter.

Patent FR-2678597-A1 (FR)
Inventor: PHILIPPE GARREC
IPC: B25J18/02
Filed: 1991-07-03
Abstract: An actuator providing substantial energy savings by using a reversible mechanical system. In particular, the actuator uses a power recovery system, particularly a screw (2) and nut (4) system, e.g. a ball-type system, wherein the pitch of the screw (2) is coarse (above 5 DEG ), or a smooth shaft system. A number of motors (9) may be placed at the ends of the screw or inside it when it is hollow. The reversibility of the coarse pitch screw/nut system allows a large portion of the electrical energy to be fed back to the supply grid or stored in a capacitor (14) during load deceleration phases. The actuator has many uses, particularly in robots.
