This paper describes a fabrication technology for embedding sensors into flex circuit with a partial glass carrier and the electrical test of the circuit. Two sensors with a device thickness of 20 μm have been embedded into the flex circuit. The total thickness of the flex including semi-additive structured metal layers did not exceed 50μm. To enable the acceleration sensor a degree of freedom to follow the excitation of the sensor a special release sequence was used to obtain a partial rigidness of the flex. With the definition of the overhang of the flex the acceleration sensor sensitivity and its resonance frequency can be adjusted. An FEM simulation has been performed to calculate the resonance frequency of the acceleration sensor and electrical measurement have been performed to validate the performance of the device.

Robust lane information is critical for lateral control system. It brings possibilities for control system to operate in strict conditions such as no lane mark detected and fuzzy lane mark because of camera limit. Also, due to the time-consuming image processing, the sample rate of lane information is always so low for control systems to make precise control. In order to deal with the problems mentioned above, IMU dynamic information is adopted and fused with the lane information from camera as a new method. It provides instant and more robust lane information for the lateral control system to operate beyond the limits of camera. A Model-in-the-loop(MiL) simulation based on PreScan-CarSim integration is built up to evaluate the performance of the proposed method. A comparison on Lane Following system(LFS) with/without sensor fusion when temporal failure of lane information occurs is made. It approves that the proposed method successfully provides accurate high sample-rated lane information and have LFS control the vehicle to travel inside the lane with less lateral deviation.

The National Aeronautics and Space Administration (NASA) is actively developing new electric and hybrid-electric aircraft propulsion technologies as part of the NASA Aeronautics Strategic Implementation Plan. The NASA X-57 "Maxwell" aircraft is the first all-electric, manned flight demonstrator using distributed electric propulsion technology, and is expected to establish greater efficiency and reduced emissions as compared to more conventional airframe and propulsion configurations. The X-57 project showcases these improvements with the understanding that the endurance and charging of the pure battery-electric storage system substantially reduce the effective range compared to conventionally-powered (internal combustion engine) aircraft. To address these technology limitations, NASA is investigating hybrid-electric fuel cell power systems for primary propulsive and secondary electrical power on aircraft as part of the Fostering Ultra-Efficient Low-Emitting Aviation Power (FUELEAP) project. The FUELEAP project is investigating integrating this power architecture into a variant (X-57-F) of the X-57 aircraft in order to improve endurance and reduce the time between flights. This paper presents the power system architecture design analysis, component descriptions, system performance, system modeling using Numerical Propulsion systems Simulation and other modeling tools, and strategies. Several design options and technology limitations are also discussed. These investigations are ongoing. © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.

Autonomous systems are able to make decisions and potentially take actions without direct human intervention, which requires some knowledge about the system and its environment as well as goal-oriented reasoning. In computer systems, one can derive such behavior from the concept of a rational agent with autonomy (“control over its own actions”), reactivity (“react to events from the environment”), proactivity (“act on its own initiative”), and sociality (“interact with other agents”) as fundamental properties \n[1]\n. Autonomous systems will undoubtedly pervade into our everyday lives, and we will find them in a variety of domains and applications including robotics, transportation, health care, communications, and entertainment to name a few. \nThe articles in this month’s special issue cover concepts and fundamentals, architectures and techniques, and applications and case studies in the exciting area of self-awareness in autonomous systems.

In this paper, we propose a rate adaptive compressed sensing for block-based DCVS framework, in which the sampling rate is estimated at the decoder side and can be sent back to the encoder via the return channel. The assignment of measurements rate (MR) is depending on the variance of the residual measurements between SI and the reconstructed CS frame. By comparing with the encoder-based scheme, the proposed scheme can achieve a comparable result with more stable and smaller transmission rate, which can briefly increase the transform efficiency as well as reduce the band width.

The development of embedded systems is currently experiencing a fundamental shift towards integrating more and more heterogeneous system building blocks into ever more complex composite systems. The aviation industry is especially hit by this development and suffers from a number of additional challenges such as long system life-times that are often significantly longer than those of individual microprocessors and other embedded devices. Since aviation software development is still often driven by the ongoing integration of new hardware it is about time to focus on a better componentization of avionic software systems. The new software architecture proposed in this paper is not only more maintainable than existing systems, it also allows for a semiautomatic integration of new hardware devices based on an automatic configuration and adaptation mechanism. As a result, airplane manufactures will be able to significantly reduce the (down) times required to integrate new software and therewith hardware into the cabin of an airliner. © 2011 IEEE.

The development of airborne software is driven by rigorous safety requirements. Hence, it needs to be certified for adhering to safety standards set by governmental agencies, based on different criticality levels. Additionally, quickly changing technologies and the resulting obsolescence of system parts increase the need for good changeability of avionic software. However, the design of current applications in the cabin of commercial airliners is mainly focussing on safety standards and on a good adjustment to the underling hardware platforms for performance reasons. Changeability has been widely neglected so far. We see component-oriented and strictly layered software architectures as a key enabler to overcome these challenges in the future. In this paper we discuss the fundamentals of a new architectural design for airplane cabin systems, integrating established design principles for modular enterprise systems with high-reliability requirements of aviation systems. Our proposed approach reduces module coupling as well as complexity and hence increases maintainability and changeability of aviation systems. Moreover, it is fully compatible with state-of-the-art aviation standards, such as ARINC 653.

In this paper we present a high temperature stable, capacitive RF MEMS switch based on a tungsten-titanium alloy. The evaluation of the temperature stability was done by annealing experiments up to 500C. Due to an intrinsic residual stress the switch features a large out of plane deflection. This allows the combination of high open-state isolation with a moderate pull-in voltage and with high restoring forces. Measurements of the high frequency performance in the 20 to 36 GHz range provided good results for insertion loss and isolation. ©2009 IEEE.
