Computer Aided Design of Suspension Mechanisms

Automobile suspension mechanisms have to date been designed using two-dimensional graphic oriented methods. Computer-aided design has allowed many two-dimensional mechanisms to be designed much more accurately. However, this has not translated to suspension mechanisms because these mechanisms are not two-dimensional but instead three-dimensional.

Cost-effective Solutions for Audio Testing

The universal popularity of mobile devices presents potentially unprecedented growth for device makers. As the user base evolves, multimedia quality features increasingly as a major determinant in market dominance. Accordingly, integration of electro-acoustic components (i.e. receiver, speaker and microphone) into home use and industrial applications is becoming more of an industry mainstay every day. With audio quality thus recognized as a key consumer consideration, providers must maximize the effectiveness of audio testing in their manufacturing process. This article discusses how high-resolution dynamic signal acquisition modules can serve as a low-cost replacement for existing sound cards while meeting all testing requirements for high-profile mobile devices.

Power Monitoring

Microchip Technology (Chandler, AZ) introduced the MCP39F511 single-phase power monitoring IC designed for real-time measurement of AC power. It is designed for use in high-performance commercial and industrial products such as lighting and heating systems, smart plugs, power meters, and AC/DC power supplies. To address industry requirements for better accuracy across current loads, additional power calculations, and event monitoring of various power conditions, the IC provides popular standard power calculations combined with advanced features. The import and export of active energy accumulation, four-quadrant reactive energy accumulation, zero-crossing detection, and dedicated PWM output have been integrated on-chip, along with the ability to measure active, reactive, and apparent power; RMS current and RMS voltage; line frequency; and power factor.

Voltage Meter

Dean Technology (Carrollton, TX) announced the HVM40B digital voltmeter for measurement of positive or negative voltages up to 40,000 Volts. It features an LED display, solid-state design, and dual-range measurement providing resolution below 20 kV. Other features include retractable feet, optional tilt handle, and optional rack-mount hardware. Input impedance of 10 giga-ohms minimizes circuit loading. It conforms to UL and CSA standards, and comes with various worldwide power cords.
