  • Standard Digital Multimeter - Auto Ranging

    MM39 - Martindale Electric Co. Ltd

    The MM39 is an auto-ranging multimeter with a large rotary switch for easy selection of the required test, even when wearing gloves. There are two test buttons, one to lock the range and the other to hold the results which are displayed on a 3½ digit LCD screen.

    The main test functions are AC voltage and DC voltage and current and resistance. The MM39 measures both AC and DC voltage between 0.1mV to 600V and AC and DC current between 10mA to 10A. There is a diode test and an audible continuity test which sounds at less than 25Ω.

  • 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.
