VAN NUYS, Calif.--(BUSINESS WIRE)--IEE, manufacturer of enhanced displays for military applications is under contract with Boeing Defense, Space & Security to design and develop an upgrade to the F-15 Passive Attack Display (PAD) for compatibility with the Advance Display Core Processor (ADCP) II. The PAD uses an ARINC 818 fiber optic interface to receive video from, and exchange messages with the ADCP II. The ADCP II facilitates the centralization of a number of critical display functions, such as the consolidation of multi-window configurations into one complete screen image for distribution to display units. This addresses the need for the ever-increasing amount of information available to operators to improve situational awareness. The F15-PAD upgrade features twelve programmable discreet interfaces, each of which can be provisioned by the ADCP II to three different types of inputs and outputs. These discreets can be used for other aircraft functions, giving the PAD a built-in service life extension. “This flight-qualified avionics display with the new ARINC 818 circuit card assembly adds a high performance digital video feature to the stable of IEE products,” said Tom Whinfrey, CEO of IEE Inc. “Not just for ADCP II compatibility,” he adds, “ but for any other avionics mission computer.” In addition to the ARINC 818 interface and programmable discreets, the upgraded PAD features an enhanced Built in Test (BIT). Celebrating its 70th anniversary, Industrial Electronic Engineers, IEE, is a trusted provider of enhanced displays for military, industrial and retail applications. From rapid prototyping of custom designs to full-scale production runs, IEE’s factory in Van Nuys, CA produces innovative displays with advanced features like multi-mode backlighting, optically bonded touch screens and lightweight, ruggedized enclosures. IEE’s direct control of critical process steps reduces costs, decreases production lead times and improves life cycle management. IEE display products are found in virtually every environment and application worldwide. For more information: visit

The aim of this study is to propose a complete instrumentation and signal processing method able to detect the presence of a person seated on the rear bench of a vehicle. The sensor is based on a piezoelectric film (EMFI sensor), designed to detect mechanical vibrations. In order to avoid confusion between humans and heavy objects or empty seats, the authors focused on the extraction of a biological signature from the acquired signals. This physiological pattern was extracted using an original wavelet denoising algorithm and was used further as a matched filter, in order to detect human presence in the vibration signals. Physiologically significant features were extracted from the output of the (on-line) filtering process and fed further-on into a classical Bayes-based classifier. After training, the proposed method yielded very promising results, the output of the classifier being almost error-free for different acquisition conditions (stopped and on-road vehicle, new and artificially aged sensor). © 2012 The Institution of Engineering and Technology.

This paper investigates the GMRES iterative method performance for solving the sublinear problem associated to the DAEs solution present in power system stability analysis in time domain. It is shown that the unpreconditioned GM-RES fails due to a phenomenon known as "stagnation". It was used an incomplete factors preconditioner with threshold - ILUT, unsuccessfully. Through the preconditioner image matrix (original power system Jacobian matrix) condition number, it was checked its bad condition, resulting, therefore, in a low quality preconditioner, justifying the GM-RES failure. The image matrix was then preprocessed (scaling, normalizing and reordering) improving its characteristics acting positively over the preconditioner quality. After these actions, the GMRES solved efficiently the linear systems associated to each numerical experiment, all presenting bad conditioned original Jacobian matrices.

In many domains such as automotive and avionics, the size and complexity of software systems is quickly increasing. At the same time, many stakeholders tend to be involved in the development of such systems, which typically must also be configured for multiple customers with varying needs. Product Line Engineering (PLE) is therefore an inevitable practice for such systems. Furthermore, because in many areas requirements must be explicit and traceability to them is required by standards, use cases and domain models are common practice for requirements elicitation and analysis. In this paper, based on the above observations, we aim at supporting PLE in the context of use case-centric development. Therefore, we propose, apply, and assess a use case-driven configuration approach which interactively receives configuration decisions from the analysts to generate product-specific (PS) use case and domain models. Our approach provides the following: (1) a use case-centric product line modeling method (PUM), (2) automated, interactive configuration support based on PUM, and (3) an automatic generation of PS use case and domain models from Product Line (PL) models and configuration decisions. The approach is supported by a tool relying on Natural Language Processing (NLP) and integrated with an industrial requirements management tool, i.e., IBM DOORS. We successfully applied and evaluated our approach to an industrial case study in the automotive domain, thus showing evidence that the approach is practical and beneficial to capture variability at the appropriate level of granularity and to configure PS use case and domain models in industrial settings. © 2016 Springer-Verlag Berlin Heidelberg

The aim of this work is to study the impedance characteristics at the electrode-electrolyte interface of the PMMA coated probe dipped in different percentages of adulterated (tap water) milk and propose a relevant equivalent circuit model for each adulteration using curve fitting program. The modeling of the probe with lumped element as well as distributed element is obtained using LEVMW software and the best-fit model is estimated. Also mathematical modeling of electrical equivalent circuit is derived and comparison of simulated data with experimental data of impedance of PMMA coated probe dipped in sample milk is done. © 2010 IEEE.

We present a novel method to adjust the beam tilt angle and tune the axial focus of an electrowetting on dielectric liquid microlens encapsulated by parylene film. The lens system consists of four control electrodes with two immiscible spherical liquid lenses of different refractive indexes encapsulated by a flexible polymer. To tilt the incident beam, the lateral position and curvature of the inner lens were modulated by ac voltage applied to the electrodes. The measured lateral position and curvature of the inner lens allowed us to estimate the position of the focal point. The tunability of the tilt angle was increased by ±2.13° at an applied voltage of 45.3 Vrms when using thin dielectric layers. The resolvable image was 80% and 68% of the aperture diameter for 20 and 50 L&S/mm, respectively, assuming that the critical modulation transfer function value was 50% for quality imaging. © 2015 IEEE.

The aim of this work is to study the impedance characteristics at the electrode-electrolyte interface of the PMMA coated probe dipped in milk and milk adulterated with different amount of urea and to propose an electrical equivalent circuit model for each adulteration using curve fitting program. The modelings of the probe with lumped parameters as well as distributed elements are obtained using LEVMW software and the best-fit model is estimated. The analytical expression of impedance is derived for the estimated electrical equivalent circuit and simulated using MATLAB. Finally the impedance value obtained by simulation is compared with experimental value obtained from LCR meter. © 2011 IEEE.
