  • Class AB Audio Power Amplifiers

    STMicroelectronics

    ST offers a complete class-AB product portfolio. As well as standard class-AB power amplifiers, ST proposes audio amplifiers in class SB (Single-ended Bridge) and SB-I (SB improved). As a result of their high efficiency, these classes reduce power dissipation by up to 50% compared to standard class AB, simplifying thermal management in current power sets. Moreover, ST has introduced a digital input to offer a clean sound, immune to external interferences. Amplifiers can now be directly connected to the DSP output without any signal conversion. ST also proposes amplifiers that are compatible with start-stop and hybrid engines.

  • Finite Element Analysis

    Response Dynamics Vibration Engineering, Inc.

    An understanding of structural dynamics is very important to sound Finite Element Analysis (FEA). We have been performing FEA analysis for over 30 years and in most cases we have used experimental data to guide our modeling. While our engineers have had undergraduate and graduate courses in FEA, it is the years of modeling and analysis of existing structures that has taught us the most by forcing a thoughtful analysis of the key structural dynamics and then going though the process of making adjustments to boundary conditions, expanding the dynamics of the model in places, and making simplifications and approximations where possible.

  • The Leading Measurement System for the Analysis of Porous Materials

    ELWIS - Autoneum Holding AG

    ELWIS (Evaluation of Light Weight Impedance System) offers a full and rapid characterization of porous materials based on the analysis of a single sample. The ELWIS system consists of the ELWIS-A and ELWIS-S components which can be used independently from each other although both applications are needed for a complete material simulation.ELWIS-A measures acoustic parameters that are needed to evaluate the acoustic performance of sound insulation and sound-absorbing multi-layer materials. An additional impedance tube for absorption measurements at higher frequencies is available for ELWIS-A.ELWIS-S measures structural parameters that are needed to simulate the dynamic and acoustic behavior of sound packages in the medium to low frequency range (including the "Poisson Ratio" for foam materials).ELWIS is very easy to operate: Thanks to its user-friendly software, the system can also be used to obtain reliable results by users with only limited experience in the characterization of porous materials.
