In order to better extract identifying features in the sound spectra of helicopter-radiated noise, a new feature extraction algorithm based on empirical mode decomposition (EMD) was proposed. Simulation results showed that the EMD algorithm can emphasize a signal's instantaneous characteristics and that the residual trend information was the mutative trend of the original signal. The proposed algorithm combined the characteristics of the EMD algorithm and spectrum composition of helicopter-radiated noise. Application of EMD to the signal analysis in transform domain (frequency domain) allowed effective extraction of the continuous spectrum. Using the smoothing filter method, when choosing the optimal α value the extracted continuous spectra are hysteretic to some extent. To overcome this disadvantage, the proposed algorithm can adaptively extract a signal's continuous spectrum, and the extracted continuous spectrum has no lag. In addition it can provide gain for a line spectrum, which can supply more useful information for subsequent target identification.

A voltage controlled oscillator (VCO) used for high precision tracking resolver-to-digital converter (RDC) has been designed based on the technology of constant-voltage charge balancing oscillator. The time-series circuit and the device parameters of VCO have been designed to satisfy RDC special characteristics. High linearity VCO (less than 0.25%) has been implemented, and the voltage-controlling gain can be adjustable. Its layout has been finished, and can be widely applied to other ASIC.

With the wide application of embedded technology and its products, much attention has been turned to the development of program to improve the safety and reliability of embedded devices. In this paper, we present a construct program of embedded trusted computing environment based on QEMU virtual machine architecture. The proposed program, simulates functions of trusted cryptographic modules by software, can not only fully consider the characteristics and design constraints of embedded systems, but also does not require additional hardware. Results from an implement of prototype system on the platform of Godson-3A are presented. It is concluded that the proposed program can prevent the destruction of malicious codes and improve the safety and reliability of embedded devices with making full use of available hardware and software resources. © 2014 IEEE.

Adaptive dynamic surface control was proposed for the uncertain DC-DC buck converter system with input constraint. The introduction of first-order filters allows the algorithm to be implemented without differentiating any model nonlinearities and suffering from the 'explosion' problem. By introducing an auxiliary control variable to ensure controller output within the specified range, an effective controller design method was developed. The proposed control law can guarantee the uniform ultimate boundness of all signals in the closed-loop system via Lyapunov synthesis, and make the tracking error converge to less neighborhood nearby origin. Numerical simulations are provided to illustrate the validity of the proposed control method.

Interactive Electronic Technical Manual (IETM) is the latest form of technical data. Now, the manner and efficiency of IETM generation can not meet the requirements. In order to solve the above problem, and reduce the manual workload and possible error by human, the manner of IETM generation based on Logistics support analysis record for materiel (LSAR) was proposed. Data characteristics of LSAR and the content model of IETM based on S1000D was analyzed, and the manner of IETM generation based on LSAR was also verified. © 2012 IEEE.

For the complicated digital bus device testing, there are two approaches: dedicated bus instrument and general-purpose digital IO instrument. The dedicated bus testers provide more advanced capability including exercising the bus, injecting errors, fully characterizing specification compliance for design validating and verification phase. This paper presents a modular solution based on the general-purpose digital IO instrument. By using built-in architectural elements such as the deep onboard memory, hardware handshaking, and an algorithmic engine, test engineers can increase the performance, modularity and simplification of test system. © 2012 IEEE.
