RFID Embraces The Cloud

One of the biggest advantages of using Radio Frequency Identification in industry and logistics today is the visibility it can provide into the process. With the use of Cloud Computing, that visibility can be achieved with greater flexibility and lower cost.

Cloud Computing provides a means of leveraging shared IT infrastructure and standardized software modules to collect and present RFID data without having to develop, maintain and most importantly, finance a redundant and load balanced infrastructure. Cloud applications also provide visibility and access anytime, anywhere, and on any device.

Get it in Writing?

I recently attended the RFID Journal Live 2011 trade show and conference in Orlando, FL. I really like this event because it brings together a diverse group of vendors, academics and customers in a setting that promotes open, honest discussions. These discussions are about not only technology, but also the state of the markets RFID serves, including aerospace, medical/heath care, defense, supply chain/retail and manufacturing, the process of RFID, like developing your ROI and even the “how to” parts of it all.

I would highly recommend attending this event to anyone seriously looking to implement RFID, especially at an organizational level. You will gain insight into the advantages of the RFID value proposition and the visibility capability all in one place, at one time.

Industrial Identification – Barcodes

Written by: Andrew Bollinger

In the realm of manufacturing and industrial automation, the need to easily track products and collect information about their whereabouts has been a problem faced by many businesses. The complexities surrounding the details of successfully identifying and recording products’ information have traditionally been solved by implementing codes on the product’s label or package.  The most widely use code today is the one-dimensional barcode. While advances in one-dimensional code reading have continued to improve, new hardware, code readers, and symbology have made an emergence and are proving to be a more reliable means to track information.

Industrial Sensing Fundamentals – Light/Dark Operate

A key step in choosing an industrial sensor is to understand the operating mode of the sensor. With digital photoelectric sensors, the input and the output are characterized by one of two sensing terms: Light Operate or Dark Operate. Light Operate (LO) describes a condition in which a photoelectric sensor’s output energizes its load when the sensor “sees” a sufficient amount of light; in other words, no target is present or detected by the sensor. Dark Operate (DO), the complement of LO, is a condition in which the sensor output energizes its load when the target is present.

Industrial Sensing Fundamentals – Back to the Basics: NPN vs PNP

What’s the difference and why should anyone care? If you’re confused by the terms PNP and NPN, then hopefully this post will shed some light on the differences between the two.  In the context of this post, they refer to the construction of a sensor’s transistor and whether it has a p-type or n-type semiconductor.

When it comes to wiring a sensor, you can think of the “N” as standing for “Negative” and the “P” as standing for “Positive”. With respect to sensors, an NPN device is one that can switch the negative side of the circuit while a PNP device switches the positive side.

The next question to ask is, what direction do you want the current to flow?

Block Vs. Tubular Photo Sensors

We do periodic training for our products and company as many industrial suppliers do. These trainings are typically for new hires, distribution staff and sometimes just to refresh our own minds. As a part of the photoelectric sensor training segment, we try to introduce the many different types of sensors we sell. But the most common types typically fall into two categories: Block or Tubular body types. And inevitably the question gets asked: “which one should I specify to the customer?” Great logical questions, but unfortunately no simple answer.

Finding Good Machine Vision Resources Isn’t So Hard Anymore

Share

Finding information that is not biased or a shrouded sales pitch for a companies products can sometimes be a difficult proposition in today’s open communication society. The world of machine vision is no exception. So when seeking un-biased information, sometimes it can seem like the deck is stacked against you.
