Codes and markings, from best-before and lot dates to EAN or data-matrix barcodes to serial batch numbers and various unique identifiers, are there to ensure traceability and product safety, to protect consumers and to avoid counterfeiting. There are many different print techniques that manufacturers can choose, such as continuous inkjet, thermal transfer or laser coding. All of these techniques have their advantages and challenges.
The approach described in this application note from Linear Technology uses four DC/DC µmodule regulators in parallel to increase output current while sharing the current equally among each device. This solution relies on the accurate current sharing of the µmodule regulators to prevent hotspots by dissipating the heat evenly over a compact surface area. The solution casts no thermal shadow on its surrounding components, further optimising thermal performance of the entire system.
In this paper, EMKA provides detailed information regarding the various materials used in the design and specification of a sealing profile, their properties and the various national and international testing methods and standards relevant to sealing profiles — a tabular format is used where appropriate. This covers comparative features of common rubber/synthetic rubber materials; comparative vulcanisate properties of NR and other SRs; fluid immersion national and international test ...
Ribbed wooden decking is common in many public and domestic gardens. However, it does not provide slip prevention as once the decking has been exposed to the elements, particularly without regular cleaning, the moss and mildew build-up will cause the surface to become extremely slippery. This application note from Heskins addresses the question of how to prevent slippery decking.
In a recent discussion with a system designer, the requirement for his power supply was to regulate 1.5V and deliver up to 40A of current to a load that consisted of four FPGAs. This is up to 60W of power that must be delivered in a small area with the lowest height profile possible to allow a steady flow of air for cooling. The power supply had to be surface mountable and operate at high enough efficiency to minimise heat dissipation. Such a solution requires an innovative design, ...
The argument over the pros and cons of whether or not to install heated water safety showers has possibly run its course with the ANSI.Z358.1-2009 standard now recommending 15 minutes of tepid water drench time for all emergency showers. In this technical article, Janet Dickinson, operations manager at Showers and Eyebaths Services, looks at what emergency safety showers are available that meet current standards.
According to Showers and Eyebaths Services, it is a good idea during milder conditions to conduct an annual service, inspection and compliance assessment for every on-site safety shower, eyewash station and — just as importantly — supply pipe. Ensuring that your emergency showers and eyebaths are fit for purpose and ready to withstand the winter freeze is essential to avoid further problems that may occur when the temperature drops.
Photomultipliers (PMTs), avalanche photodiodes (APDs), ultrasonic transducers, capacitance microphones, radiation detectors and similar devices require high-voltage, low-current bias. Additionally, the high voltage must be pristinely free of noise. This application note from Linear Technology describes a variety of circuits featuring outputs from 200V to 1,000V with output noise below 100µV measured in a 100MHz bandwidth.
As this Rittal-sponsored white paper explains, competitiveness in a global economy requires continuous innovation and accelerated go-to-market cycles, as well as agility in deploying resources. This is particularly true for midsize companies that have to leverage technology to gain an advantage over peers and larger corporations.
The medical device industry has always been dependent upon product innovation to drive growth. With today’s aging global population and expectations for living to an older age, the medical device industry is poised for a sustained period of extreme growth fuelled by a level of innovation that is scheduled to accelerate. Most companies are growing. Nearly all are innovating at an increasing pace. The common challenge is how medical device manufacturers and their suppliers can simultaneously ...
There are three main standards currently in use which directly relate to the purity of the compressed air quality and testing requirements for industry. As this article from Beko Technologies explains, the most commonly used standard is the ISO8573 series and in particular ISO8573-1:2010.
Technical article: a new rotating voice coil motor for Meteosat third-generation satellites download
The goal of this paper from Cedrat Technologies is to present the motor that meets the requirements of the Meteosat third-generation satellite system.
Companies want to raise the bar on innovation from incremental improvement to the kind of innovation that shows up in the annual report.
This application note forms Linear Technology’s eighth circuit collection publication. Topics include a JFET-based DC/DC converter powered from 300mV supply; a bipolar transistor-based 550mV input DC/DC converter; a floating output, variable potential battery simulator; and more.
Multi-degree-of-freedom (DoF) mechanisms are widely required in micro or macro manipulation fields as well as in optronics functions. Commonly available mechanisms may be divided into two main categories. The first is industrial robots (serial or parallel). These offer a large range of motion in rotation and translation. Their resolution is usually limited in the sub-millimetre range.
