The present invention concerns a composite article comprising a plurality of layers, wherein at least one of the layers is a defective polymeric layer. The defective polymeric layer has at least one artificial defect, in the form of a volume of air confined by walls made of said defective polymeric layer, and by layers adjacent thereto. The invention further provides the use of a composite article for calibrating equipment and a method for making such a composite article.

Method for making composite articles with artificial defects

A strain gauge including: a system including a transmission coil, a magnetostrictive material layer and a receiver coil wherein an alternating transmission signal is applied across the transmission coil and an induced signal is induced in the receiver coil, the intensity of the detected signal across the receiver coil being a measurement of strain, wherein frequency of transmission signal is near to a resonance frequency of the system.

Magnetostrictive type strain sensing means and methods

The present invention provides a method for determining whether or not moisture appeared in a hidden place during a period T, the method comprising: (i) introducing to the hidden place a moisture sensitive element; the moisture sensitive element comprising: a) a dielectric substrate coated or impregnated with an intrinsically conducting polymer and b) probes connecting the substrate to a resistance meter; (ii) measuring and recording the electrical resistance of the substrate at two or more times during the period T; (iii) determining whether or not moisture appeared in the hidden place during the period T according to the changes in the electrical resistance of the moisture sensitive element that occurred during period T. The present invention further provides method and system for alerting against a possible appearance of corrosion in a hidden place, a moisture sensor for use in the method or system, and a method for producing a substrate comprised in such a moisture sensor.

Method for detecting hidden corrosion and a sensor for use in the same

A dental implant which contains a bi-cortical anchor apparatus for insertion into a jawbone, the anchor apparatus including a tool receptor for interacting with a tool which facilitates insertion of the apparatus. An implant member arranged for insertion into a jawbone, the member containing a cervix to secure a dental prosthesis and a through conduit to support an anchor apparatus. A complementary system including an implant member and a template, the latter meshing with and helping align the implant member. A method for inserting the implant member into a bore in the jawbone. The method includes drilling a channel in the jawbone through a drill-bit guide channel and inserting a bi-cortical anchor apparatus through the channel and through a conduit of an implant member, anchoring at least two portions of the anchor apparatus.
