US Digital - Resolution, Accuracy, and Precision of Encoders
Three important concepts deserve attention: Resolution, accuracy, precision.
At first glance, it may seem that all three mean roughly the same thing. You may wonder if they’re interchangeable; indeed, many people speak of them as if they are. After all, if an encoder has high resolution, doesn’t that mean it’s accurate? And if it’s accurate, then it has to be precise, right? (Please note: the answer to these last two questions is a firm no.) In fact, the terms are independent of each other. Each refers to a specific encoder characteristic, and they are not interchangeable.
To clear up any confusion, download the free whitepaper to learn what resolution means for incremental encoders, noting any differences for linear and absolute encoders. Following that the author moves on to accuracy, and finishes with precision. Along the way, you'll get tips on how to use knowledge about each term to make the best encoder selection, and how to calibrate a system once the encoder is in place.
Accelerating Innovation in Automotive Design
Learn how real-time 3D and VR are radically transforming the car industry.
Download this whitepaper to learn how To match the fast pace of automotive design, OEMs have made big strides in speeding up development timelines from concept to showroom. Nonetheless, competitive and economic pressures are compelling manufacturers to compress ramp-up time even further. Optimizing 20th-century production processes will not be enough to develop the vehicles of tomorrow. Learn why manufacturers must not just optimize, but thoroughly transform the way they design, engineer, build, market and deliver mobility.
Optimizing Your Business through Broad Based Automated Information Systems
We have used the old adage Time is Money forever at just about every level of management looking to sum up the complex path to success. This still applies in today’s business models, however, leading and industry changing businesses have recognized now that access to instant insight is profit.
Successful leaders and their organizations understand the key information components that yield improved profit through real time information availability and the rapid decisions conceived from this information. In many cases automated information collection and rapid access to it is the core reason these organizations dominate their field today and will continue to do so in the future.
Tactile and optical measurement techniques each have their strengths, and there are certainly measurement tasks that require only one of the two.
In systems designed for automated precision measurement, users are typically balancing accuracy of measurement, speed of operation, and cost to purchase and operate. The need for tradeoffs and sometimes-difficult choices will always be with us, but the introduction of multisensory measurement throughout the last several decades, along with subsequent improvement in its capabilities, offers opportunities for improvement in all three areas.
There are two available contact-scanning technologies: passive and active. Passive scanning probe heads use springs to hold the stylus in its neutral position and strain gauges to measure deflection.
Both record surface data based on the movement of a stylus connected to a scanning head. The difference is what goes on inside the scanning head. The distinction between touch-trigger (single point) measurement and scanning is well known. Touch trigger has been described as a “woodpecker” approach measure a point, move to another location, measure again, and repeat until the job is done. The surface or feature condition between the points that are actually measured may be estimated by interpolation, but significant deviations can be missed. Also, because each measurement is a discrete operation and the measuring head must be repositioned to measure the point, the process can be very slow. Scanning, on the other hand, is accomplished with a fluid and continuous movement that can quickly and accurately measure hundreds or thousands of points along a path as the stylus moves across a surface. But while all scanning technologies offer advantages over single-point measurement, all scanning probe heads are not the same.
An overview of system level design for wireless communications equipment.
This white paper presents an overview of system level design for wireless communications equipment. It will be useful not just to those involved in the development of new communications systems, but also to designers of new products using existing systems, or anybody seeking to develop new architectures and/or components to reduce product cost and/or size. It also describes the benefits and implications of developing highly integrated System on a Chip (SoC) solutions, which dominate in today's high volume communications products.
Read what Tara Meinck, Application Engineer with Spirol Int’l Corp. USA says about ensuring bolted joint integrity.
Compression Limiters are used to protect plastic components in bolted joints and maintain a threaded fastener’s clamp load by eliminating plastic creep. To function properly, bearing surface beneath the bolt’s head must extend over the Compression Limiter to contact the plastic component. If this bearing surface is too small, the host component may not be retained by the bolt resulting in a poor joint.
