Known problems with subsubmenus(The submenus are visible all the time, the subsubmenus are those that drop down.) The intended behaviour of the subsubmenus is that they appear on hover and disappear again as soon as the cursor leaves. This happens on browsers that use HTML as defined by the internationally agreed standards (W3C). Microsoft has chosen to deliberately ignore the standards (see dedicated page), so Internet Explorer gives slightly different behaviour. We have tried to fix this several times with different javascript tweaks, but without full success. If you find a fix for this that does not violate the HTML standards, then please email me with it! Menus don't disappear when the cursor leaves the boxHowever, they do disappear when the cursor hovers over another subsubmenu item. This is the best solution we have found for Internet Explorer while staying with the standards. If the subsubmenu list is in your way, hover over another submenu item that has a shorter subsubmenu list. Menus never disappear once extendedIf you use Internet Explorer AND have ActiveX enabled, then the subsubmenus never disappear. This can be solved by your disabling ActiveX on your machine. If you get the popup window saying that some ActiveX content has been blocked, don't allow it but leave it blocked. |
Robot of the WeekSurgery wormAn aid for heart surgeons
Minimally invasive surgery (MIS) replaces the wide incision used for classic operations with a few small incisions, through which the tips of robot arms are inserted: one holding a camera and others holding surgical tools. These arms are controlled by the surgeons carrying out the operation. Our surgery worm is an articulated arm designed for heart surgery, more precisely Coronary Artery Bypass Grafting (CABG). The articulated snake-like forearm can carry various tools along twisting paths, minimising impact on the patient. This reduces patient trauma, postoperative pain and recovery time The fixture is a good example of a Micro Electro Mechanical System (MEMS), with force-actuation and shape-control being intrinsic properties. A prototype of the surgical instrument has been machined in Paris and will be tested in vivo. We are currently developing new task-oriented end-effectors, such as a self-operating sewing rig able to operate with a single thread. The surgery worm was developed by a collaboration between the PMAR Lab of EURON member 95, the University of Genova, Italy, and the LRP laboratory of the University of Paris 6, France.
