It’s no secret that we live in an automated world that seems to be moving at a mile a minute in terms of how fast the technology behind the automation moves. Most of us tend to admire the way things around us move and work, but for those who work in industries that manufacture these ‘things’, they are more concerned with the ins and outs of the electro-mechanical assemblies that are the heart of our automated environment.
So, you may be asking yourself, “What exactly are electro-mechanical assemblies?” It’s a good question with a basic answer but not near enough time to describe the scope with which these little mechanical miracles make our lives easier. Per The Engineering Council out of London, these types of “devices convert electrical energy into mechanical movement”. Basically, electricity creates movement which, in turn, leads to a function taking place. An example of this would be the robotic arms heavily used in manufacturing.
Even if you’re not completely familiar with the engineering behind all of this, getting the basics down is good knowledge to have in your back-pocket. Here are three things you need to know about electro-mechanical assemblies:
Machines versus Products – Manufacturers of electro-mechanical assemblies often look at what they do as more than provide a product to a customer. Depending on the complexity of the project, they may use the word ‘machine’ to better describe what they’re bringing to the table.
Hardware and Software Changes – A top-notch manufacturer does right by its customers by maintaining records of previous projects. Having records allows a manufacturer to knock-out a customer order if there are no changes from a previous project, but it also allows both the customer and manufacturer to look over specs from before & see what options are available for current & future needs.
Up-to-Date Manufacturing Design Techniques – If there is one thing to know about electro-mechanical assemblies, it’s that you need to work with a manufacturer that not only has quality & experience recognized across a number of industries, but also actively pursues licensing and certification relevant to the products it provides. The manufacturer must also actively keep up with trends in manufacturing processes and strive to provide state-of-the-art service to its customers.
Electro-mechanical assemblies are seemingly omnipresent in nearly all areas of society purely because of the amount of automation we as individuals insist upon. As technology advances and the needs of the individual grow, so too must the ability for manufacturers of electro-mechanical assemblies to keep up with demand. In order for your business to remain relevant in your specific industry, it will be vital to choose the right manufacturer that not only understands your current needs but is also equipped to exceed your expectations & prepare your business for the future.
A barcode scanner is an electronic tool, which could be used to read and output a host of ‘printed barcodes’ to the computer. It comprises a lens sensor, lens and light source for translating the optical impulses into electrical impulses. Barcode scanners are made of decoder circuitry that analyses a barcode’s image data that is provided by the sensor and sends the content of the barcode to the output port of the scanner.
Different Types of Barcode Scanners
There are various kinds of barcode scanners that are based on the technology employed or the housing design.
The Barcode Scanners Classified on the Basis of Technology Used
o Omnidirectional Barcode Scanners: The omnidirectional barcode scanner makes use of a series of curved or straight scanning lines of different directions in starburst form. These scanners generate beam patterns in different orientations permitted them to read the barcodes to these readers at various angles. Many use the polygonal single rotating mirror and a medley of differently fixed mirrors for generating complicated scan patterns.
o Laser Scanners: The laser barcode reader work in the same way as the pen type barcode readers except that they make use of the ‘laser beam’ for the light source. They make use of the rotating prism or the reciprocating mirror for scanning the laser beam forth and back across barcode reader.
o Pen-Type Scanners: The pen-type barcode readers comprise the photodiode or the light source which is placed side by side on the pen tip or wand. The photodiodes measure the light intensity that is reflected back from the light source as pen tip crosses space and each bar in printed code. The photodiode produces the waveform which is used for measuring the space and bar width in the barcode.
Barcode Readers Based on the Housing Design
o Handheld Scanner: This type of scanner is available with the handle as well as the trigger button for turning on ‘light source’.
o Stationary Scanner: The stationary scanners are table or wall-mounted. These barcode readers are widely used at ‘checkout counters’ of the supermarkets as well as the other retailers.
o Fixed-Position Scanner: The fixed-position scanner is the industrial barcode scanners that are used for identifying products during logistics or manufacture. These barcode readers are used on the conveyor tracks for identifying pallets or cartons needed for routing to a different shipping location or process. The holographic scanners are joined by another application to the check weigher for reading the ‘barcodes’ of any placement or orientation and then weighs the specific package. Such systems are widely used in farm automation or factories for shipping and quality management.
o PDA scanner: The Auto-ID PDA or the PDA scanner are basically built-in barcode readers or are attached barcode scanners.
o Automatic reader: The automatic barcode reader is the back office tool used for reading the barcode documents at a speed of 50,000/hour.
o Wireless or Cordless Scanner: The wireless barcode scanner is battery-operated and is not connected to the main electricity. It is used for transferring data to a connected device such as the PC.
These are the various barcode readers, which find wide application in the various industries.
Over a period of time, computers have become an indispensable part of businesses. Installation of computers, their support and maintenance are services all organizations require. As businesses grow, the number of computers in the organization also increase. It becomes imperative to establish a systematic way to connect these computers so that they function in a hassle-free manner. Therefore, computers are interconnected in various ways. This is the concept of a computer network.
What is a computer network?
A computer network can be understood as a number of computers connected together to share resources. The most common resource shared is the internet. Other resources can be printers, file servers, etc. The computers in the network may be connected through an Ethernet cable or wirelessly through radio waves.
Now we will see how the individual computers in a network are connected:
Computers connected in a network are referred to as nodes.
In this case, there is a central node from which connections are provided to individual computers. In this case, even if there is any problem with a particular cable, the other computers can continue to function undisturbed. On the flipside, this type of connection requires a lot of cabling.
In this case, all the computers are connected by a single cable. The information that is intended for the last computer needs to travel through all the nodes. The chief benefit is that it requires minimal cabling. However, if there is any fault in the cable, all the computers are affected.
In this topology, all the computers are connected through a single cable. The end nodes are also connected to each other. The signal circulates through the network to reach the intended recipient. In case, a network node is configured incorrectly or there is some other issue, the signal will make numerous attempts to find the intended recipient.
Collapsed Ring Topology:
In this case, the central node is a network device known as the hub, router or switch. This device runs in a ring featuring plugins for cables. And, each computer is independently connected to the device through individual cables.
Each organization chooses its own topology of the computer network to ensure a streamlined functioning of their computers. Once the computers are connected, offices also have separate cabling closets, which is essentially a space containing a switch device that connects to the network.
There are a number of computer network companies that provide the services of installation, maintenance, and support services ensuring smooth and streamlined functioning of your systems.
