A device for monitoring gases present in a breathing mask. A gas sensing element carried by the breathing mask senses the partial pressure of a gas present in the breathing mask and outputs signals corresponding to the sensed gas partial pressure. The gas sensing element may comprise a gas-sensing material configured to emit, in response to light excitation, an optical signal at an intensity corresponding to the partial pressure of a sensed gas.

A method for embedding a line in a substrate. A line embedding head in positioned relative to a surface of the substrate. The line from an output port in the line embedding head is output at an angle relative to the embedding head such that the line is embedded in the substrate.

A method for manufacturing an EMI suppression device includes formulating a dielectric material from a polymer composite material that includes a thermoplastic resin /thermosetting resin and a conductive filler. A sheet that comprises the polymer composite filler is prepared. The top surface of the sheet is then laminated with a conductive foil. The laminated sheet is cut into one or more sections, where each section has a laminated top surface and a middle section that comprises the polymer composite material.

An embedded material and an embedding apparatus and method. A compatible solute can be dissolved in a solvent. The object to be embedded can be coated with the solvent/plastic solution using, for example, addition and/or condensation polymerization. The solvent can be removed. The coated object can be inserted, snap fit, or submerged into a partially 3D printed substrate with or without the aid of ultrasonic embedding, thermal energy, joule heating, and/or the use of adhesives, and the 3D printing process resumes in order to fully embed the coated object within the 3D printed substrate.

The present invention concerns a reinforcing material comprising at least one fibrous reinforcement associated on at least one of its faces with a thermoplastic porous layer, said thermoplastic porous layer(s) representing at most 10% of the total mass of the reinforcing material, preferably from 0.5 to 10% of the total mass of the reinforcing material, and more preferably from 2 to 6% of the total mass of the reinforcing material, characterized in that said thermoplastic porous layer or each of said thermoplastic porous layers present comprises a so-called reactive thermoplastic polymer or consists of one or more reactive thermoplastic polymers, a reactive thermoplastic polymer carrying NH2 functions in an amount greater than 0.15 meq/g of reactive thermoplastic polymer and/or carrying COOH functions in an amount greater than 0.20 meq/g of reactive thermoplastic polymer.

The invention also concerns processes for manufacturing such reinforcement materials, preforms, processes for manufacturing composite parts and composite parts using such reinforcement materials.

A system is described for reinforcing a thermoplastic workpiece including a subject surface and an underlying workpiece body volume. At least one substantially linear Z-pin having proximal and distal pin ends longitudinally separated by a pin body is provided. The proximal pin end is in direct contact with the subject surface. An ultrasonic energy source applies ultrasonic energy to the Z-pin to ultrasonically heat the Z-pin and thus locally melt the workpiece material of the subject surface and/or the workpiece body to create a melted workpiece material. The proximal pin end and at least a portion of the pin body of the Z-pin are penetrated into the melted workpiece material to create an inserted Z-pin length. The inserted Z-pin length is maintained in the workpiece body volume by solidified melted workpiece material around the inserted Z-pin length to reinforce the workpiece. A method of reinforcing a workpiece is also provided.

A Z-pin including a first bi-metal structure having a first metal strip and a second metal strip bonded together, where the first and second metal strips have different coefficients of thermal expansion, and a second bi-metal structure having a third metal strip and fourth metal strip bonded together, where the third metal strip and the fourth metal strip have different coefficients of thermal expansion. The first and third metal strips are selectively secured together at at least one discrete location so that heating of the Z-pin causes the first and second bi-metal structures to deform relative to each other. The Z-pin is inserted into a composite laminate structure while it is in its uncured state, where curing of the composite structure causes the first and second bi-metal structures to deform relative to each other to lock the laminate layers together.

A wearable accessory capable of communicating data to actuators or from sensors is disclosed. The wearable accessory includes a conductor wire disposed in a moldable medium according to a predetermined pattern, the moldable medium being an electrically insulating material, the conductor wire terminating at an input and an output.
