20120247034 | ENCLOSURE FOR A PLEASURE POOL, WHICH COMPLETELY OR PARTIALLY ADOPTS THE SHAPE OF A ROTUNDA - The invention relates to an enclosure for a pleasure pool, which is completely or partially in the form of a rotunda and which comprises a plurality of rotary angular roof elements. The aforementioned rotary angular roof elements form an angular portion of the rotunda and rotate about the same vertical axis, each element comprising a frame framing at least one cylindrical filler panel. The frame includes a lower circular edge that rests on the ground and an upper edge from which at least two sections extend towards the rotation shaft, which sections join so as, together with the upper edge, to form a frame for an angular portion of the roof-forming filler panel. The roof elements are mounted to rotate about the same vertical axis in order to move between an open position and a closed position. The enclosure is characterised in that each frame framing a cylindrical filler panel is provided with a section (C, C) that is curved in relation to the axis of rotation of the element and which is disposed in the internal portion between the lower edge and the upper edge, forming a handrail. The invention is suitable for pleasure pool covers. | 10-04-2012 |

20140312817 | ELECTRONIC CIRCUIT AND METHOD FOR TRIGGERING A SEMICONDUCTOR SWITCH - An electronic circuit comprises at least one semiconductor switch mounted with its switching path in series with an inductive load to be triggered, and at least one freewheeling element that interacts with the semiconductor switch during switching phases and is also mounted in series with the load. A control unit controls a control connection of the semiconductor switch with a variable control current as a function of the time profile of a voltage measured at the freewheeling element and/or as a function of the time profile of the voltage measured at the switching path. A method for triggering a semiconductor switch of such a circuit, triggered by a variable control current for switching, the control current predefined as a function of the time profile of a voltage measured at the freewheeling element and/or as a function of the time profile of the voltage measured at the switching path. The electronic circuit according to the disclosure is advantageously used for triggering semiconductor switches of a bridge inverter circuit, in particular for operating an EC motor. | 10-23-2014 |
