摘要:
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.
摘要:
Asynchronous information is provided by a sensor (10) having a matrix of pixels disposed opposite the scene. The asynchronous information comprises, for each pixel of the matrix, successive events (ev(p, t)) originating from this pixel, that may depend on variations of light in the scene. A model representing the tracked shape of an object is updated after detecting events attributed to this object in the asynchronous information. Following the detection of an event, the updating of the model comprises an association of a point of the model with the event detected by minimizing a criterion of distance with respect to the pixel of the matrix from which the detected event originates. The updated model is then determined as a function of the pixel of the matrix from which the detected event originates and attributed to the object and of the associated point in the model, independently of the associations performed before the detection of this event.
摘要:
The invention relates to a device for generating a torque on an output member (3) in response to a torque setpoint, comprising: a first driving member comprising at least one motor (1) with a first power, or small motor, with a shaft (2) onto which the output member is connected; a second driving member including at least one motor (11) having a second power higher than the first power, or large motor, with a shaft (12) rotatingly connected to the output member via viscous coupling means (4); driving means (50) programmed for powering the second driving member (11) in response to a torque setpoint (M cons ) so that the viscous coupling means provide a viscous torque (M visq ) corresponding to the torque setpoint and, in parallel, to power the first driving member (1) so that it provides the additional torque between the torque setpoint and the viscous torque during the time necessary for the viscous torque to reach the value of torque setpoint.
