The invention relates to a damping device for opposing a reaction in response to the advance of a manual control member (28), said device including at least one chamber containing a magneto-rheological fluid, one or two means for generating a magnetic field (6.1, 6.2) that can be adapted in the magneto-rheological fluid in order to modify the apparent viscosity thereof, a mobile member (4) capable of translation for shearing the magneto-rheological fluid and to be mechanically connected to the manual control member (28), said mobile member (4) including a blade with a longitudinal axis (Y) including holes and/or recesses and/or protrusions.
摘要:
The invention relates to a method and a device for locating interaction on a large surface enabling it to be rendered touch-sensitive. The method according to the invention is based on modelling of the distribution of stresses between capacitive sensors distributed over the surface and estimation of the position closest the interaction by seeking a minimum cost associated with the proximity of sensor measurements to established models.

This display device (10) having a deformable surface comprises: - a plurality of actuators having mobile elements (26, 28) that can be moved so as to deform the deformable surface, these mobile elements being distributed in the space occupied by the deformable surface, and - a set (42x, 42y) of position sensors for sensing the position of at least one touch, said position sensors likewise being distributed in the space occupied by the deformable surface, and - an elastic flexible membrane (40) placed against the mobile elements (26, 28), extending through the space occupied by the deformable surface and able to accompany the deformation of the latter. Furthermore, the set of sensors (42x, 42y) is secured to the elastic flexible membrane (40) and distributed in a regular manner in the space occupied by the deformable surface so as to form an array of electricity conductors that are able to accompany the deformations of the elastic flexible membrane (40).
摘要:
The invention relates to a touch-sensitive partition wall or household furniture item (10) comprising a surface (14) that can be touched by a user. The invention also comprises a matrix array (S) with rows (16) and columns (18) of sensors disposed against or in the surface (14) that can be touched, and a connection interface (20) for connecting the matrix array (S) of sensors to an electronic control system (22). The connection interface (20) can be programmed for the individual activation/deactivation of each row (16) and column (18) of the matrix array (S) of sensors.
摘要:
An ultrasonic motor comprising a rotor (18) shaped at least partially spherically and two actuators (2, 2') each comprising an element made from a piezoelectric material in the shape of a plate comprising at least one contact edge (4, 4') in contact with the rotor (18), said actuators (2, 2') also comprising, on one of the faces of same, electrodes intended to bias piezoelectric materials in a bending mode and in a longitudinal mode. The contact edges (4, 4') are concave and are formed by an arc of a circle of which the radius substantially corresponds to the radius of the surface of the rotor (18), said arc of a circle extending angularly according to a predetermined angle such that the bending mode and the longitudinal mode in which the piezoelectric material is biased are at the same frequency.
