In this article, an analytical model for current-induced vortex core displacement is developed. By using this model, one can solve the equations of motion analytically to determine the effects of the adiabatic and nonadiabatic spin-torque terms. The final ...
The invention relates to an immobilizing device for a toothed wheel suitable for the field of horology where it can be part of a direct- or indirect-impulse escapement, in particular in a wristwatch. This immobilizing device (1, 2, 3, 4, 5, 6) comprises: — ...
In the frame of the development of a very high speed synchronous drive, a DC/DC converter is studied. In this context, this paper presents the comparison between two two-commutation-cell topologies. A multichannel and a multilevel converter are formally co ...
This paper presents a method to dynamically filter the position and the speed of a linear actuator during its closing. A previous paper presented position detection without external sensor but, by simply deriving it, the corresponding speed was not usable ...
In the scope of haptic touch feedback actuators, we discuss the phenomenon of creating the haptic experience by squeezing the air film between the user finger and the actuator. The focus is given in the modeling of the squeeze film effect. An existing anal ...
Objective: Vascular prostheses currently used in vascular surgery do not have the same mechanical properties as human arteries. This computational study analyses the mechanisms by which grafts, placed in the ascending aorta (proximal) and descending aorta ...
The development of very high-speed motors has evolved fascinatingly in the last few years. Due to their speed, their low weight and their high power density, the need for such motors has recently increased for various different applications. Among them, su ...
The idea is to integrate a rotating or linear motor in a touring ski binding and automatically adapt the heel height according to the slope the user is mounting. This would avoid multiple painful movements of the skier to raise or lower the heels. The slop ...
This paper presents preliminary results in the frame of the development of a very high speed synchronous drive with a rated power of 6 kW at the rated speed of 180 krpm taking place in the context of a university-industry partnership. Due to the very high ...
