20140182050 | FUNCTIONAL PROTECTIVE MATERIAL, IN PARTICULAR FOR USE IN PROTECTIVE CLOTHING - The invention relates to a functional protective material, in particular having a protective function with respect to chemical poisons and/or biological toxins and/or chemical and/or biological hazardous materials, such as warfare agents, wherein the functional protective material has a multi-layer structure that comprises a planar, in particular textile, substrate material and a membrane that is associated with the substrate material, in particular connected to the substrate material, wherein the membrane in itself is permeable to air and water vapor and therefore is provided with a plurality of micropores preferably distributed substantially evenly over the membrane surface. According to the invention, an operating parameter of the membrane can be changed in such a way that the membrane assumes two different operating states, wherein in the first operating state the micropores of the membrane are open and in the second operating state, the micropores of the membrane are at least predominantly closed. | 07-03-2014 |

20130060490 | METHOD FOR DETERMINING THE TORQUE AND/OR ANGULAR SPEED OF A ROTATING SHAFT AND A DEVICE FOR CARRYING OUT SAME - A method allowing the reliable and accurate calculation of the torque of a shaft using two phonic wheels and a sensor, the method including correlating the signal resulting from a rotation or one sixth of a rotation with the signal resulting from the subsequent rotation or one sixth of a rotation. The length of time between two passages of teeth is calculated by interpolating the cross-correlation function using least squares interpolation. | 03-07-2013 |

20150320568 | VERTEBRAL IMPLANT, DEVICE FOR VERTEBRAL ATTACHMENT OF THE IMPLANT AND INSTRUMENTATION FOR IMPLANTATION THEREOF - This disclosure provides various vertebral implants, devices for attaching a vertebral implant and implantation instrumentations. In some embodiments, the implant includes a first body and a second body, each having a face with shapes and dimensions mating that of the other body and forming mutual fitting means, thus allowing assembly of the bodies by sliding along a sliding axis. In some embodiments, a locking means is retained in one of the bodies and an abutment portion may move from an open position allowing sliding for the assembling of the bodies to a closed position locking the bodies in assembly by the contact between the abutment portion, by contact with an abutment of the other body, the abutment being oriented angularly to the sliding axis and the abutment portion passing from the open position to the closed position elastically by flexure or torsion. | 11-12-2015 |

20140238773 | METHOD AND SYSTEM FOR PNEUMATIC CONTROL FOR VIBRATOR SOURCE ELEMENT - Method, source array and source element that generate seismic waves. The source element includes an enclosure having an opening covered by a piston; a local supply accumulator fluidly communicating with an interior of the enclosure, a pressure of the fluid inside the local supply accumulator being larger than a pressure of the fluid inside the enclosure; a local supply valve located between the local supply accumulator and the enclosure and configured to control a flow of the fluid from the local supply accumulator to the interior of the enclosure; and a controller configured to control the local supply valve such that the pressure inside the enclosure does not fall below a first preset value based upon an ambient pressure of the enclosure while seismic waves are generated. | 08-28-2014 |
