Design is a balance struck between style, functionality, technology, and construction (often as a compromise). But what makes a design “elegant”? The iPod is inarguably an elegant design, but then again so is the standard wooden mousetrap. This month we’re running some articles on design and comments on “elegant” design. Let us know if you agree with the authors or add comments of your own at www.ecnmag.com/designtalk-elegant-design.aspx
With a life cycle of 3,000 operations, ITT Interconnect Solutions' Universal Contact stamped contact uses pre-loading and anti-lift designs and comes with dome contact points and “side wings”. Addressing solderless component interconnection applications
Capable of running in many .NET frameworks, National Instruments’ Measurement Studio 8.5 software includes user interface controls, such as ASP.NET Web Forms, ASP.NET scientific, and ASP.NET AJAX server. The ASP.NET AJAX-compatible programming comes with NI-DAQmx and NI-SCOPE .NET driver support, as well as advanced network variable communication functions and memory-optimized analog waveform read operations. The Microsoft Visual Studio 2008
Designed to address advanced automation applications, Technosoft’s TMC-3D 8-axis motion controller includes a digital servo drive to control up to 8 Technosoft intelligent drives (including itself) via CAN-bus
One issue facing design engineers is echnology selection. Choosing a device today is more than just an exercise in packaging and pin out, there are often multiple technologies and/or methodologies to choose from. Here is a collection of viewpoints from a group of engineers on how they select tech.
Researchers at TU Delft (Netherlands) and the FOM Foundation for Fundamental Research on Matter have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.
Able to drive 4-wire DC fans and blowers, Control Resources’ SmartFan Cirrus-6 fan speed controller accepts commands from a custom or an I2C interface. The controller handles tach pulses from 6, 12, 24, or 48 VDC fans
Consolidating multiple sensor functions in a single 14-pin LGA ECOPACK SMT package, STMicroelectronics’ FC30 sensor provides 3D orientation as well as click detection to recognize mouse-button controls. Accepting a nominal 2.5V at 0.3 mA, the 3.0 × 5.0 × 0.9-mm device exhibits an accuracy of ±3 degrees with a max acceleration of 10,000 g for 0.1 ms. Features of the RoHS-compliant
Microchip Technology announced the MRF24J40MA FCC-certified Radio-Frequency (RF) transceiver module which services the 2.4 GHz unlicensed Industrial, Scientific and Medical (ISM) short-range wireless frequency band for the IEEE 802.15.4/ZigBee specification or proprietary wireless-protocol
Provided in a BGA package with a footprint 1.1 mm² and a height of 0.5 mm, a family of Hall Effect ICs from ROHM Electronics are presented as the smallest devices of their type (a 1.6 × 1.6 × 0.6-mm package is also available). Features include compensation and push-pull CMOS logic output circuitry , as well as integrated dynamic-offset cancellation.
Giving off even heat to the contents within, Omega Engineering’s DRUM-DHW-55 Series of OMEGALUX drum heaters wrap around a 55-gallon drum and have a built in thermostat calibrated from 10 to 218°C. The spring-and-hook devices are resistant to mechanical damage and attack from many chemical substances. The drum heaters have a built-in electrically electrically-grounded metal screen and
Populated with the NXP LPC3250 microcontroller, the phyCORE-LPC3250 ARM9 based Single Board Computer (SBC) can operate in ultra-low-power mode down to 0.9V. Targeting demanding embedded applications, the 70 × 58-mm device includes power management, an FPU, and SD/SDIO, USB OTG, and Ethernet connectivity
Generating 0.5 to 3.5 Vp-p high amplitude waveforms, the MU181020A-013 Variable Data Output option from Anritsu Company configures with the MP1800A/MT1810A Signal Quality Analyzer/PPG to eliminate the need for an external amplifier
Giving an engineer the ability to monitor and report rotational speed, Orion Fans’ DC fans trigger a 5-V TTL or an “open collector” alarm signal to indicate that they have stopped or slowed significantly. The UL/cUL- and TUV-approved devices have a 2 period-per-revolution square-wave frequency and can
Delivering up to 2,000 W in a 5.5" × 10.7" × 1.6" package, the UFE series of programmable AC/DC front-end power supplies from Emerson Network Power yield a power density as high as 22 W/in³. Up to three supplies can deploy on a single 1U high 19"rack for up to 6 kW of available power, and up to 4 kW of redundant power. The power supplies can also be stacked up to 6U high
