In wireless-communication and bio-medical technologies, no device can be brought to market without proof that it satisfies safety standards related to Specific Absorption Ratio (SAR). In the case of hand-held devices such as cellular phones, the concern is often about power density absorbed by the brain. In other applications, such as radio transmitters, Magnetic Resonance Imaging (MRI) , or medical implants transmitting data wirelessly, electromagnetic power can be absorbed by any organ. Ensuring that safety standards are met is essential for any equipment manufacturer. In this white paper, we will show how this can be done with ANSYS HFSS

Switched Mode Power Supplies (SMPS) generate Electromagnetic Interference (EMI) by virtue of their inherent design characteristics. Internal SMPS circuits can generate undesirable emissions that are rich in harmonics and cause electrical interference both internally to the circuit in which the power supply is installed, and to other electronic equipment in the vicinity of the emission source. This paper examines the rules and regulations governing control of EMI, discusses types of noise generated by SMPS, and provides basic guidance for EMI mitigation.

The use of additive fabrication processes is what differentiates direct digital manufacturing (DDM) from conventional manufacturing methods, and it is from these technologies that unique advantages and opportunities arise.

With an integrated motor/drive system, units can be daisy-chained off a single power supply, dramatically reducing the cabling and associated installation costs.

Customers might not know of all the requirements at the start of a project, so it may be wise to leave a little expansion room for additional memory or function keys, or providing a color display even though the project may not explicitly call for it.

Sensortechnics’ LBA differential pressure sensors measure ultra low air or gas pressures from 25 Pa (0.1 in H2O) full scale. The sensors are based on a new and innovative MEMS technology which integrates a micro-flow channel within the silicon sensor chip. At the same time the sensors use the proven principle of inferring differential pressure from a thermal mass flow measurement.

Traditional pneumatic directional valves use either a poppet, spool or sliding plate operating principle. The most common design is the spool principle as it offers a good balance of reliability and durability, versus cost, for many industrial automation applications.

About a decade ago, the debate about Single-Use Systems (SUS) vs. traditional stainless-steel was just a whisper: reusable steel was favored because it was the system that process designers and users had relied on for years.

Power engineers have challenges with designs becoming more complex as the performance and capabilities of integrated circuits continue to increase. Digital solutions can help solve these issues, as digital power management addresses system level efficiency in bringing products to market more quickly. The technology also provides enhanced communication and the ability to monitor, control, and configure, minimizing system power and energy consumption.

Between 1980 and 2005, 281 combustible dust explosions killed 199 American workers and injured 718 more. A white paper prepared by Newson Gale Inc. provides the numbers and background data on the incidence of such accidents in terms of materials involved and those processes most vulnerable, plus guidelines for preventing static sparks, the most common ignition source of such incidents.


Detection & Shielding Of Noise In Stepper Motor Systems

Flex circuit design vs. PCB flex circuits still only account for about 15% of the overall printed circuit market. So it’s understandable that there are still questions about the design of a flex circuit vs. traditional printed circuits boards. Designers are warned that the design of a flex circuit is different, but it’s not that difficult and adding this knowledge to your experience toolbox is not as daunting a task as it may seem.

When faced with the challenge of reducing cost without sacrificing quality, damping greases can be useful tools in a design engineer’s bag of tricks.

Powder and bulk solids manufacturers have always had an inherent problem: once product is developed, it needs to be moved. Whether it is through a hopper or feeder system or merely transporting the material, the product needs to be moved. This sounds easy enough, but it can be very complex.
