Symbolic Techniques for Model Code Optimization: FMI Applications

Since its inception, the FMI standard has become the primary method for model transfer and co-simulation, providing a smooth, error-free technique for design engineers to deliver their work without manual integration or resorting to other proprietary tools. At the same time, advanced symbolic technologies have emerged that provide extremely fast auto-generated code for the implementation of dynamic system models and enable advanced analysis applications. This paper describes symbolic techniques employed under the hood for dynamic system model formulation and optimized code generation. One application where the FMI standard has been used is for generating a functional mockup of an automatic transmission from MapleSim, and implementing it in dSPACE's SCALEXIO to perform a full-vehicle, real-time simulation.

Assisting An Aging Population: Designing Medical Devices With Force Sensing Technology

With the geriatric population on the rise, design engineers are challenged with designing responsive, noninvasive, user-friendly medical devices that cater to the needs of an older generation. Patients are looking for cost-effective, easy to use assistive tools that help them regain independence and confidence in their everyday life. Force feedback is a key feature for many of these devices that provide the user and doctor with great insight that ultimately results in better quality of life for the patient. Medical devices with force feedback allow design engineers to create innovative products that differentiate them from the competition.

Spectrum Analyzer Fundamentals – Theory and Operation of Modern Spectrum Analyzers

This primer examines the theory of state-of-the-art spectrum analysis and describes how modern spectrum analyzers are designed and how they work. That is followed by a brief characterization of today's signal generators, which are needed as a stimulus when performing amplifier measurements.

Receiver requirements for a TDOA-based radiolocation system

Emitter location based on measuring the time difference of arrival (TDOA) at multiple receiver sites has been available for several decades. In the past, the greatest challenge lay in time-synchronizing the various spatially separated receiver sites. Extremely complex methods were needed to precisely synchronize multiple receivers. Without adequate synchronization, the results of this location method are unusable because even small synchronization errors lead to significant errors in emitter location. For example, when using a single sensor, an error of 100 ns in measured time means an error of 30 m in the estimated distance. When using multiple sensors, the errors are additive and lead to unusable location results.

Introduction into Theory of Direction Finding

Applications of direction finding While direction finding for navigation purposes (referred to as cooperative direction finding) is becoming less important due to the availability of satellite navigation systems, there is a growing requirement for determining the location of emitters as the mobility of communications equipment increases:

dB or not dB? Everything you ever wanted to know about decibels but were afraid to ask...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels.
