Micron-sized subwavelength structured photonic sensors could allow critical thermo-mechanical phenomena in manufacturing processes to be monitored, while offering opportunities for fundamental understanding and better control of manufacturing processes. To implement these novel sensors into real manufacturing processes, the micro photonic sensors can be embedded at critical locations in metallic structures, which are still heavily used in hostile manufacturing environments. This paper presents the study of design, fabrication, and testing of integrated microring sensors. Various thin film optical materials were studied. Single ring resonators were designed. A new approach to fabricate metal embedded microring sensors was developed. Sensors fabricated on silicon wafers were tested and the Q factor was measured to be around 2000, the free spectrum range (FSR) was about 5 nm. Preliminary results of metal embedded sensors are also presented.

Recent developments in integrated microphotonics have led to unprecedented potential toward robust sensor enhancements for manufacturing systems. These micron-sized subwavelength structured photonic sensors could allow critical thermomechanical phenomena in manufacturing processes to be monitored while offering immunity to electromagnetic interference, resistance to hostile environments, multiplexing capabilities, and high rates of data collection. To implement these novel sensors into real manufacturing processes, the microphotonic sensors can be embedded at critical locations in metallic structures, which are heavily used in hostile manufacturing environments. This paper presents the study of design, fabrication, and characterization of integrated microring sensors. Various thin film optical materials were studied and single ring resonators were designed. A new approach to fabricate metal embedded microring sensors was developed. Metal embedded optical microring temperature sensors were characterized. The Q factor of the metal embedded microring sensors was measured to be around 2000, while the free spectral range was about 5.2nm. The temperature sensitivity of the metal embedded microring sensor was 24.2pm∕°C.

The Cost

Abstract Advanced jet training still relies on old concepts and solutions that are no longer efficient when considering the current and forthcoming changes in air combat. The cost of those old solutions to develop and maintain combat pilot skills are important, adding even more constraints to the training limitations. The requirement of having a trainer aircraft able to perform also light combat aircraft operational mission is adding unnecessary complexity and cost without any real operational advantages to air combat mission training. Thanks to emerging technologies, the JANUS project will study the feasibility of a brand-new concept of agile manoeuvrable training aircraft and an integrated training system, able to provide a live, virtual and constructive environment. The JANUS concept is based on a lightweight, low-cost, high energy aircraft associated to a ground based Integrated Training System providing simulated and emulated signals, simulated and real opponents, combined with real-time feedback on pilot’s physiological characteristics: traditionally embedded sensors are replaced with emulated signals, simulated opponents are proposed to the pilot, enabling out of sight engagement. JANUS is also providing new cost effective and more realistic solutions for “Red air aircraft” missions, organised in so-called “Aggressor Squadrons”.

It is widely recognized that industrial production inevitably results in an environmental impact. Energy consumption during production is responsible for a part of this impact, but is often not provided in cradle-to-gate life cycles. Transparent description of the transformation of materials, parts, and chemicals into products is described herein as a means to improve the environmental profile of products and manufacturing machine. This paper focuses on manufacturing energy and chemicals/materials required at the machine level and provides a methodology to quantify the energy consumed and mass loss for simple products in a manufacturing setting. That energy data are then used to validate the new approach proposed by (Overcash et.al, 2009a, and 2009b) for drilling unit processes. The approach uses manufacturing unit processes as the basis for evaluating environmental impacts at the manufacturing phase of a product’s life cycle. Examining manufacturing processes at the machine level creates an important improvement in transparency which aids review and improvement analyses.

Auch kleinere Unternehmen mit komplexen Herstellungsprozessen müssen heute in der Kleinserie die Effizienz und Geschwindigkeit in der Produktion erhöhen. Zentraler Bestandteil ist dabei eine schlanke Fertigungssteuerung in einem ganzheitlichen Produktionssystem. Der Fachbeitrag zeigt, wie auch bei hoher Komplexität wesentliche Ansätze der „Lean Production“ genutzt werden, um die Produktion von Ingenieurkeramiken durch die intelligente Vernetzung bereichsspezifischer Methoden zu optimieren.   Today, even small companies with complex manufacturing processes in low-volume production have to improve efficiency and speed in manufacturing. A core aspect is lean manufacturing control within an overall production system. This article shows how the main approaches of Lean Production can be applied even to a highly complex environment. The intelligent integration of specific methods for each control unit helps to enhance the production of ceramics.

The paper considers ways of increasing labour productivity in manufacturing radioelectronic system components. We used systems engineering methods to develop a new approach to describing manufacturing processes that makes it possible to reduce assembly duration. We present a promising technology for describing a manufacturing process in small-lot production using digital 3D modelling and a Lego -like approach to design building instructions for children's construction sets.

Vibration Data

The continuous development of information and telecommunication technologies has led to the possibility of transferring data and information between people in real time, in just a few seconds, which has led to the emergence of new approaches to data collection. An example is crowdsourcing (networked mass of people), which involves collecting a large amount of defined data from a large number (mass) of people through the Internet, that is, embedded sensors in smart devices. These are most often mobile phones and then it is about the concept of mobile crowdsourcing – which is more widely accepted under the term crowdsensing. This paper shows how smart devices (mobile phones or tablets) can collect vibration data that occur while driving in road traffic – and still be used to detect irregularities in road infrastructure (potholes, bumps, etc.) in real conditions.

Base Station Antennas

This work aims to study and design base station antennas with metallic electromagnetic band gap (EBG) materials able to create a sectoral radiation pattern presenting at least a beamwidth. The use of metallic structures offers a new approach to industrial partners seeking to reduce costs and facilitate design procedures. A new method allowing the improvement of both the directivity and the bandwidth by using a printed antenna array is studied.
