Basic Barcode Reading Technology – Scanners, Readers and Wireless

The technology used to read barcodes is relatively simple, but there is little information available for the novice. This is intended to be an introduction to the scanning, processing and presentation of barcode information.   Musicskanner.com

Scanners

A scanner is a device that converts the image of a barcode into electrical pulses. There are four basic ways of doing this: contact wands, active non-contact (AKA laser scanners), and passive non-contact, which can be cameras or linear CCDs (charge coupled devices). All of these devices have similar outputs, strings of electrical pulses that mimic the white/dark and width of the bars. With the exception of cameras, a scanner will always include a light source, either LED or laser.

Wands are the simplest, but have the most limitations. A wand has a light source, focusing lens and a light detector. It has no moving parts, which makes it the most rugged of scanners, but it also means the operator must move the wand over the code. This takes some practice. The second major limitation: the wand must touch the barcode. A barcode under a plastic case or an overly-thick wrapper cannot be read by a wand.


Laser scanners
 have moving parts that are easily damaged. They consist of a laser light, a set of mirrors and a detector. At least one of the mirrors moves, which allows the laser beam to scan a code. Multiple mirrors can redirect the beam in many directions. A laser beam is very thin and this allows the scanner to read barcodes at long distances. They can also make multiple scans of the same code in very short periods. These properties make them ideal for retail stores and factory use where the distance between the barcode and the scanner can very from scan to scan.


CCD scan engines 
will contain a light source (most often LED), lenses and a linear CCD. The barcode is illuminated and the lenses focus the image on the CCD. Scanning is performed by reading the reading the charge levels on each of the CCD elements. CCD detectors can have 1024, 2048 or even more elements. Like a wand, a CCD scanner has no moving parts. These scanners do not make contact with the barcode, so they can work at a distance. Because of the need to focus the barcode’s image on the CCD strip, the distances within which a CCD scanner works is much more limited than for a laser scanner.


Camera scanners 
use an array of CCDs and lenses, and some them include a light source. They have lower-resolution detectors, which limits their use to special 2D matrix barcodes, unless close-up focusing is an option on the camera. Webcams and cellphones can be used in this way.


Light to data

The output of a scanner is a string of electrical pulses. Generally two voltages are used for the pulses, a high-state and zero. If viewed with the right equipment, the high & low states would map directly to the black & white bars of a code. The conversion is done by part of the reader, or in some applications by a keyboard wedge.

The pulse string is processed in several ways. The first is a look at the lengths of the pulses. Many barcodes use constant width bars and spaces, but the most common barcode, the UCC/EAN code, uses four widths. Each barcode type has a font. Most of them also have guard bars, which indicate where the code starts and stops. The guard bars may also give a clue as to the direction of the scan. The UPC barcode uses three bars at the ends and five in the middle. The guard bar patterns are not used for numbers or characters. So by noting the locations of the guard bars, the scanner can actually combine scans of the left and right sections to make a complete code.

Once the type of barcode has been identified, the pulse string is broken into groups of bars that form characters. When decoding a UPC, each character is four bars: 2 black, 2 white.

Once each character has been identified, there might be a check sum calculation to verify the complete code is valid. The UPC barcode performs a calculation determined by each digit’s position and compares that to the last digit of the code.


Data to information

The converted data is now in a digital form. This may be a coding pattern like ASCII or it might be keyboard codes. The former is standard for stand-alone readers, the latter more common in point-of-sale or office use.

Keyboard wedges that connect scanners to computers will use keyboard codes, so the computer accepts the input as if someone were typing the code.

wireless reader can either store the digital codes or transmit them to a central system. Many handheld, portable readers contain small amounts of memory that can store 100-150 barcodes before they need to be connected to a computer to download. Connections can be via USB or a serial port. In almost all cases, specialized software is required to read the data. Wireless readers that transmit to a central system do not need data storage, but they are limited in their range. This is most useful within a warehouse or a factory.


Making use of the data

If a barcode is not routed to a central computer, it needs to be displayed in a human-readable format. Devices that can do this are called portable data terminals (PDT).This is a bad term, because only the portable part is true. A portable data terminal is a free-standing barcode-reading system.

A PDT will contain a scanner, a processor, memory, storage and a display. Often, they are actually laptop or palm computers to which a scanner has been added. A few are purpose-built and optimized to read barcodes and translate that to useful, human-readable form. A PDT can contain tables or databases which allow it to look up scanned codes and tell the user what they represent and how many there are.

A PDT tends to be very expensive, because it has so many capabilities. Those based on laptops can cost several thousand dollars. Even palm devices can be $600-$1000 dollars once the scanner has been added. Businesses can integrate PDTs into their inventory systems, and some of the lower-cost devices can be placed in the hands of all of their field personnel. Items used while servicing customers’ equipment can be scanned on site and the information loaded into the main inventory system later for billing and inventory management.

Some purpose-built PDTs are small enough and inexpensive enough to be used as consumer devices. Given a scanner, storage and a display, consumers can use these devices to inventory their music, movie and book collections.

The inventories can be stored on their home computers or stored remotely, or both. Websites that cater to collectors can frequently convert barcodes to more useful information like titles, authors and composers. Small, pocket-sized devices designed for portability can actually be carried at all times, and used to check new purchases against items already collected, just by scanning codes.

 

How to Make a Your Own Custom Stretched Canvas For Fine Art Painting

Are you an artist looking for a way to save money and make a custom canvas stretcher at the same time? Many “starving artists” need to be as economical as possible when it comes to purchasing art supplies. One way to both save money and make a better quality canvas stretcher is to make it yourself and then stretch the canvas on the stretcher yourself. This is particularly true for art students who may be on an even tighter budget than your professional or amateur “starving artist”. Making your own canvas stretcher is also a good idea if you are making large canvases or special shaped stretchers that may not be available in art stores. Cheaper and better are two great reasons to make your own.  clamps lowes

EQUIPMENT;

1. Miter saw, manual or power miter saw (a saw that will cut a 45-degree angle)
2. Corrugated nails
3. Wood glue
4. Corner clamps
5. Hammer
6. Small 1-inch finishing nails
7. Canvas pliers
8. Canvas(unprimed)
9. Gesso
10. Light duty staple gun

Step 1. Make a sketch with the dimensions of your canvas and then calculate exactly how much wood you will need for the project.

Step 2. Take a trip to your local lumber store or Lowes or Home Depot. You will need to hand pick the 1″ X 2″ lumber which the stretcher will be made with. Make sure you choose good quality and straight pieces of white pine wood. Also hand pick some ¼-inch quarter round molding, the same length as the 1″ X 2″ lumber your selected.

Step 3. Glue the 1’4-inch quarter round molding to the top outside edge of the 1″ X 2″ wood so that one flat side of the quarter round is glued to the 2″ side of the 1″ X 2″ and the other flat side is flush with the 1″ edge. Nail the quarter round to the 1″ X 2″ with one-inch finishing nails.

Step 4. Cut the 1″ X 2″ with the quarter round attached, to the proper length using a mitre saw, cutting at a 45-degree angle. Cut four 1″ X 2″ pieces about 6″ to 12″ long (depending on the size of the canvas) for braces in the four corners. Cut these braces with a mitre saw at a 45-degree angle. Cut one 1″ X 2″ piece as a middle brace for the canvas; cut it at the regular 90-degree angle. This brace will be in the middle of the canvas, butted on each side to the inside edge of the stretcher frame.

Step 5. Now that you have all your pieces cut, you need to put them all together. If you have them, use four corner clamps to hold the corners together at a 90-degree angle while you glue and nail the corners together, using corrugated nails or equivalent fasteners. Let the glue dry, take the stretcher frame out of the corner lamps and attach the four corner braces and the middle brace using glue and corrugated nails or equivalent.

Step 6. Now you have your frame! Next step is to stretch the unprimed canvas onto the stretcher frame. The canvas should be about 4 inches larger than the stretcher frame on all four sides so that it will wrap around to the back side. Lay the unprimed canvas on the floor and center the stretcher on the canvas with the stretcher frame upside down with the quarter rounds touching the canvas. Starting in the center of each side of the frame, wrap the canvas around the back of the frame and staple to the back of the frame. Pull the canvas tight on the opposite center and staple. Continue this process going from the center to the corners stapling the canvas approximately one-inch apart.

Step 7. Now you have a stretched canvas! The final step is to tighten the canvas even more with hot water and then finally gesso the canvas. Boil some water on the stove, get a rag or a sponge and wet the entire surface of the canvas with the hot water. This will shrink the cotton material, making the canvas nice and taut on the stretcher, perfect for painting. Let the canvas dry and apply a coat of acrylic gesso to protect the canvas and to have a base layer of white paint which will make your colors more intense.

Step 8. Grab a cup of coffee, sit back and admire your awesome hand-made custom canvas. Now take a few minutes and contemplate how to compose your next masterpiece on your awesome new canvas!

Within the 1940s and 1950s, few participated in health willingly. Amongst those that did had been Jack LaLanne, Victor Tanny, Joseph Gold, Joseph Weider, and Les and Abbye “Pudgy” Stockton. These health pioneers, amongst others, drew folks to the seashore in Santa Monica, California-the unique Muscle Seaside. Guests got here to observe their feats of power and acrobatic shows. Increasingly viewers grew to become members, and these folks, initially on the perimeter, grew to become part of the cultural mainstream. Jack LaLanne, Vic Tanny, and Joe Gold all began fitness center chains with bodybuilding as their principal focus.

Long Flight Time and Why It Is Important in Drones

The amount of time a drone can fly is very important. This is one of the specifications that you need to check before you even think of purchasing a drone for whatever reason. Every drone is unique by itself. Drones have got the battery and motor combinations that affect the flight time very significantly and these are some of the things that you need to check. Sometimes the motor and battery determine the price of a drone and therefore the higher priced ones tend to offer a longer flight time than the others.

Importance of flight time

Having a poor battery and motor may not allow you to enjoy everything that comes with enjoying a drone to the fullest. Sometimes drones can be used to take aerial photos, especially when you are hosting an important function or a gathering of friends. Having a drone that can stand the whole event may be very interesting as it will be able to capture so much more throughout any function that you want. Choosing a drone that has reasonable flight time should be considered to avoid mishaps.

If you are using a drone commercially, then the duration of flight is very important too. This is due to the fact that you will be able to handle so much more per flying session. It may get a little weary if you have to keep on charging your drone every now and then. When the flight time is longer, your entertainment will be continuous. You should invest in great batteries for the drone. Get more information about   best drones for kids

Different scenarios and the best flight time

Entertainment

Image result for drones for kids

If the drone you are looking to purchase is for your entertainment, a 15 minute flight time is a good idea. This is mostly if you are not an advanced user. Such time should be adequate to keep you well entertained for a single session. Such drones are not expensive either and are the best if you want to learn more about how to fly a drone.

Aerial/Vlogging photography

Aerial photography and Vlogging are not really time consuming. For most users, 20 minutes should be enough. However, for someone who prides himself as an advanced operator or a person who is tech-savvy and wants a longer time, then 25 minutes or more isn’t as bad.

Filmmaking

If you are in professional cinematography or film making, the drones you need to use should be able to fly for a long time. Sometimes professionals have to rely on extra batteries as well as a charging hub. The combination tends to work really well. This is how they are able to have some power on drones throughout. Using drones is really important, especially where they have to get lots of footage.

Improving the flight time

If you feel that you are not getting enough from your drone, then you should try improving the flight time. You can actually buy a more superior battery than the one you already have. Before you make the purchase, ensure that the drone supports the battery. You can actually buy a couple of batteries to ensure you have power throughout.

 

Winter Sports Vs Summer Sports

Winter sports Vs summer sports, who will win? As you may already know seasons require different types of sports for the younger and older generation. It definitely depends in which state, area and country you live as well. The season and temperature require different types of sports. Let’s have a look at some sports you can perform in each season. SKY777

Winter sports:

Some classical winter sports are definitely, indoor swimming, gymnastic, basketball, ice hockey and indoor tennis. These sports can be performed at any given season, regardless of whether it is cold or not. People like indoor activities during the colder season because it simply helps them to stay fit and in shape during the entire year. Some people tend to only do sports in summer which leads to a non balanced lifestyle and health. If you want to become successful in the areas of health, profession, and sports you definitely need to do winter sports as well.

Summer sports:

People mean there are more summer sports than winter sports, so what is true? Well in summer you have the possibility to face many outdoor activities such as soccer, basketball, street hockey, beach activities, water sports, tennis jogging, hiking, climbing etc. There are probably as many possibilities in summer as there are in winter. The only difference is that we human beings tend to be lazy when it is cold outside. Summer sports help us to stay in shape and enjoy the sunny days during the hotter and warmer season. There are different kinds of activities you can perform that are single player and multiplayer. Playing soccer, basketball, and street hockey requires at least 2 players, better more. The fun and enjoyment factor is multiple times higher if you play with your friends, family and other people you do know. Doing sports alone is mostly boring and not appropriate. However, sports such as jogging and swimming can be performed by one person and don’t require a second person.

How do you know which winter and summer sports are going to be optimal for you? You simply have to try different activities to find the one that will match your flavor and tendency best. However, if you spend time with people you love, and aim to get in shape you probably won’t mind doing multiple sports at a season. Every sport has a different focus and trains different muscles. Just going to the gym might be too one-sided, so you should be motivated to do at least 3 sports at a time.

 

Property Values to Get Double Boost When the Real Estate Market Recovers

Property estimations are probably going to get a twofold lift when land advertises far and wide begin to recoup. This will happen on the grounds that two key factors that influence the valuation of salary delivering property will both move toward a path that will positively affect esteems. These two key elements incorporate property wage and capitalization rates (or top rates).

Examination of recorded developments of top rates for business property has demonstrated that top rates move in a counter-repeating style. As it were, the point at which the land advertise is breaking down with rising opportunity rates and falling rents, similar to the case today for some, land showcases around the world, capitalization rates tend to increment. More about parc esta condo

This bodes well since when the market is breaking down the danger of property estimation decreases is impressively higher. Given higher market chance, financial specialists are requiring and can anchor higher returns. Since capitalization rates speak to the wage return at the season of procurement, they have a tendency to go up when advertise chance increments. The legitimacy of this recommendation is evident today in numerous property markets, where top rates have risen impressively because of the quickly decaying economic situations over the most recent a half year.

Under a similar justification, when the market is reinforcing with declining opportunity rates and rising rents, top rates tend to diminish. The reason is that in a rising business sector financial specialists are more idealistic and they expect rents and property estimations to keep climbing. Given the lower danger of declining esteems and solid desires for future capital additions, financial specialists will buy property at costs that permit a lower starting salary return, bringing about lower advertise capitalization rates.

Property estimations advantage from bring down capitalization rates on the grounds that, as indicated by the immediate wage capitalization approach, property estimation can be assessed as the proportion of the property’s net working wage (NOI) over the market capitalization rate that applies to the particular property. Since the top rate is in the denominator of this recipe, it implies that keeping the NOI of a property consistent, the lower the market capitalization rate the higher the property estimation.

At the point when the land showcase begins to recuperate, the estimations of wage delivering properties will profit from bring down top rates, as well as from higher property salary. A recuperating land showcase is portrayed by rising rents. Rising business sector rents increment the pay winning capability of a property bringing about a higher net working wage. As showed before, net working salary is in the numerator of the property-estimation recipe utilized by the immediate wage capitalization approach. In this manner, keeping market top rates steady, an expansion in the net working pay of a property will bring about a higher valuation.

As of now land advertises far and wide are enduring the results of the worldwide money related and monetary emergency. The International Monetary Fund predicts that most economies will balance out or come back to development by 2010 or 2011. The planning and quality of the financial and property advertise recuperation will contrast from nation to nation. In any case, when that time comes and land markets begin to recoup, property estimations are probably going to get a twofold lift, as rental rates begin to rise and top rates begin to fall.

How to Ensure Your Roof Is Ready Before Installing Solar Panels

It’s an exciting experience when you finally decide to switch to solar energy. After plenty of research, you’ve determined that you want to invest in solar panels. You’re so excited that you’ve already started to research solar installers in your area. Still, one little question currently holds you back from making the move to solar: “What else should I do before asking for a quote?” Connecticut solar company

We suggest checking to make sure your roof is as ready for a solar panel installation as you are. There are three important questions you consider before you make the move to solar energy:

  • What does your roof look like?
  • What is the condition of your roof?
  • How much shade does your roof get throughout the day?

Your answers can help you determine if it’s time to get quotes for solar panels. Let’s dig into each question, shall we?

What Does My Roof Look Like?
A quick inspection of your roof is a big first step in determining whether it’s ready for a solar panel installation. There are three major factors you should consider:

  • The age of your roof
  • The roofing material
  • Potential obstacles for solar panels

Age of the Roof

The older your roof, the more likely it is that you’ll need to do some work before you invest in a solar array. If your roof will need to be replaced within the next 10 years, it’s best to replace it before solar panels are installed. This will save you from having to remove and reinstall them when the roof is replaced.

Roofing Materials

While solar panels are routinely installed on metal and asphalt roofs, some roofing materials, such as slate and Spanish tiles, require more care when installing solar panels. If your roof is made of a delicate material, you should talk to a professional roofer for their recommendation on mounting panels on your roof.

Potential Obstacles

Solar panels need to be laid down in straight rows. This means obstacles, such as vents and dormers, can limit how many panels can fit on your roof. A good solar consultant can potentially design around these obstacles, but it can still impact your overall solar potential.

What is the Condition Under My Roof?

Depending on the condition of your roof, you may need to replace it before you install new panels. Inspect your roof for the following signs:

  • Damaged rafters or trusses
  • Leaks or stains in the attic or on walls
  • Mildew
  • Dark, “dirty-looking” spots on the roof

If your roof is showing any of these signs or hasn’t been replaced in the past 10 years, consider getting a roof repair estimate from a professional. Shop around and see what you can find. If the area you want to install panels is inaccessible, consult your home’s blueprints for the structure of your roof.

How Much Shade Does My Roof Get?
Shade from trees and other buildings can limit the production of your system. Because of this, it’s best to avoid installing panels in shady areas on your rooftop, if possible. If necessary, trees can also be trimmed to optimize unshaded area on your roof. Use Project Sunroof to see an estimate of how much sunlight your roof sees each year and which areas of your roof would be best for panels.

Make Sure Your Roof is Ready for Solar Panels
A little preparation can make a big difference for your solar energy system. By considering three simple questions about your roof, you can put your panels in the best position for maximum production.
