Abstract: Method for visual tracking of at least one object represented by a cluster of points with which information is associated, characterised in that it includes steps to: receive (E1) data representing a set of space-time events, determine (E2) the probability that an event in the set belongs to the cluster of points representing the at least one object, for each event in the received set, determine (E3) whether or not an event belongs to the cluster of points as a function of the determined probability for the event considered, for each event in the received set, update (E4) information associated with the cluster of points for at least one object, for each event for which it was determined in the previous step that it belongs to the cluster of points, calculate (E4, E5) the position, size and orientation of the at least one object as a function of the updated information.

Abstract: A device, having first and second motor units, for generating a torque on an output member in response to a torque setpoint. The first motor unit includes at least one motor of a first power, or small motor, having a shaft to which the output member is connected. The second motor unit includes at least one motor of a second power higher than the first power, or large motor, having a shaft rotationally connected to the output member via viscous coupler, and computer programmed, in response to a torque setpoint, to power the second motor unit so that the viscous coupler provides a viscous torque conforming to the torque setpoint. Further, in parallel with this, the first motor unit is powered so that it produces the additional torque between the torque setpoint and the viscous torque until the viscous torque reaches the value of the torque setpoint.

Abstract: A method of making a metal electrode on the surface of a hydrophobic material (7), the method comprising the steps of: [1] bringing one end of a capillary (5) containing a fluid that includes particles of metal dissolved in a solvent close to a zone of the surface of the material (7); and [2] illuminating said zone by means of laser radiation (3) so as to have the effects of causing a drop of fluid to flow from the capillary, of depositing the drop on the zone, of evaporating the solvent contained in the drop, and of annealing the metal particles on the surface of the material in order to form the electrode.

Abstract: The invention relates to a device for generating a torque on an output member in response to a torque setpoint, including a first motor unit including at least one motor of a first power, or small motor, having a shaft to which the output member is connected, a second motor unit including at least one motor of a second power higher than the first power, or large motor, having a shaft rotationally connected to the output member via viscous coupling means, and servo-control means programmed, in response to a torque setpoint (Msp), to power the second motor unit so that the viscous coupling means provide a viscous torque (Mvisc) conforming to the torque setpoint and, in parallel with this, to power the first motor unit so that it produces the additional torque between the torque setpoint and the viscous torque until the viscous torque reaches the value of the torque setpoint.
