Abstract: A signal tracking system including: one fixation element to be secured to a rigid body part of the patient surrounding a target body part, the fixation element further including a mapping element, one tracker element to be secured to the fixation element to track, in real time, the internal tracker, and a control unit including a memory to store an internal referential and one image displaying the target body part and one fixation element. The control unit is designed to define, inside the internal referential, at least one 3D frame position attached to the at least one fixation element, and to precisely locate each point of the target body part, the control unit is further designed to precisely localize, in real time, the internal tracker inside the target body part.

Abstract: A mechatronic device includes two arms extending from a base in a first direction and shaped to be handheld by an operator, the two arms having free ends forming a gripper and arranged to move closer together by rotation from a rest position to an active position, a motor housed in the base, an actuator mounted between the arms, and a means for controlling said actuator, the actuator connected to the motor so as to be driven in movement in translation in the first direction. The actuator also has a first contact surface that forms a cam with a respective second contact surface on each arm, the first contact surface remaining engaged with the second contact surface. The control means controls the movement in translation of the actuator to produce a movement in rotation of the arms that applies a chosen force of the gripper in its active position.

Abstract: A touch interface includes a display screen and detects an approach and a position of a user's finger with respect to the screen. The interface displays at least one first graphical element associated with a first touch selection zone and lying in a first region and at least one second graphical element superimposed on a second touch selection zone, and lying in a second region distinct from the first region. The interface estimates a trajectory of a point of the finger and a point of impact of the trajectory on the screen. The interface displaces, when the point of impact is detected in one of the regions, the graphical element of the region and the associated touch selection zone in the direction of the point of impact, and then, when the point of impact exits the region, restore the display of the graphical element to an initial state.

Abstract: A touch interface includes a display screen. The interface detects an approach and a position of a finger of a user with respect to the screen. The interface displays on the screen at least one graphical element associated with a touch-selection zone, surrounding an anchor point of the graphical element on the screen. The interface estimates a trajectory of a point of the finger and an impact point of the trajectory on the screen, and moves the graphical element in the direction of the impact point, when a distance between the anchor point and the impact point falls below a first threshold.

Abstract: Asynchronous information is provided by a sensor having a matrix of pixels disposed opposite the scene. The asynchronous information includes, for each pixel of the matrix, successive events 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 detection, the updating of the model includes 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.
