What is ARINC 429?

ARINC 429 is a standardized data-bus protocol designed specifically for use in aircraft cockpits. Modern aircraft are extremely complex machines and cockpits often contain several different computerized systems. ARINC429 makes it possible for sophisticated avionics systems of different types and from different manufacturers to coexist and work together as a single cohesive unit in the aircraft cockpit setting.

From autopilot systems to navigation computers and GPS systems, from fuel management systems to cabin oxygen and climate controls, there are many different computer systems in the instrument panel and many of these must interface with each other in order to perform their functions.

Like a home or office network, ARINC 429 allows digital components to intercommunicate with each other via a standardized physical interface and data structure. To start with the ARINC standard describes specific universal connections for both power and data. This allows avionics and aircraft designers much more freedom to create new and innovative concepts for aircraft control systems. Furthermore, it allows new technologies in navigation and aircraft management to be easily retro-fitted into existing aircraft. The duties of aircraft maintenance and repair personnel are simplified from this "one size fits all" standardized interface as it removes any guesswork when installing such avionics devices.

ARINC 429 increases the safety of aircraft by reducing pilot workload. The system allows flight information to be used and displayed in many different ways. Airspeed information for example, is required by the autopilot system the flight navigation computer and the fuel management system. ARINC429 allows this information to be automatically transmitted from the sensor system to these control systems without requiring any input from the pilot. Furthermore the system is also used to monitor flight information to detect dangerous situations and the aircraft may be equipped to automatically respond to emergency situations. The autopilot for example, may be programmed to pitch forward if the aircraft appears to be entering a stall.

Like all aircraft systems, AIRINC 429 is also designed to be as robust and dependable as possible. With this in mind ARINC 429 cabling is shielded 78 ohm twisted-pair to reduce RF signal interference. A 10 volt allowable differential in signal communication allows reliable data transmission even with up to a plus or minus 5 volt over or under volt. This allows the system to continue operation in emergency situations and in the presence of extreme environmental conditions.

Our modern high-capacity high-efficiency airliners and cargo haulers would not be possible
without the advanced avionics made possible by the ARINC 429 system .

RFID - The Future

Radio Frequency Identification (RFID), technology of the future, has long established itself in our everyday lives. It is already deployed in various areas ranging from efficient inventory management and road-toll collection through to timing the performance of individual participants, in mass sporting events. With its enormous potential it is only right that RFID is now on everyone's lips.It builds a bridge between the physical world of a product and the virtual world of digital data. The technology thus meets the demands of companies cooperating with each other in a closely knit value chain and is also being deployed promisingly in all sectors of the economy. This way RFID will soon be considered an indispensable part of the value chain.



RFID - An Overview


RFID or Radio Frequency Identification is a system that uses radio waves to transmit an object's identity. There are several methods of identifying objects using RFID, but the most common is to store an ID or serial number that identifies a specific product along with other information, on a tag, which is a small microchip attached to an antenna. The antenna enables the chip to transmit whatever identification information it contains to a reader. The reader converts the radio waves from the RFID tag into digital information that software systems can use for processing.



Typically, when a reader reads a tag, it passes three things to a host computer system: the tag ID, the reader's own ID, and the time the tag was read. By knowing which readers are in which locations, companies can know where a product is, as well as what it is, and by tracking the tag data by time, they can know everywhere it's been.



Most industry analysts argue that RFID tagging is a transformational software development activity that will ultimately change the way businesses plan, price, distribute, and advertise products. But for the present, enterprise application vendors are extending their products to handle an expected boom in RFID data.



Until recently, a bar coded item used to sit on a retail shelf and did not generate any data until it was scanned by a bar code reader. And then the data was read only once. RFID, on the other hand, is a passive technology that does not require human interaction to scan. A reader can extract location and product description data from a tagged item every 250 milliseconds. Some readers are capable of reading data from 200 tags per second. The result is a data increase of more than one thousand times above traditional scanning methods.



With the rate at which the market competition is rising, inefficiencies in a company's value/supply chain and their continuous efforts to shore up internal security are driving the rising demand for RFID. The retail trade is playing a decisive part in the broad-based roll-out of RFID projects. RFID represents an all-encompassing structural business concept that far transcends simply superseding the bar code. Considering the current scenario, RFID systems are rapidly gaining significance. This holds especially in areas where they can be used to manage processes within the value chain. With this favorable situation, the market for RFID systems are likely to grow globally from EUR 1.5 bn to EUR 22 bn between 2004 and 2010 (average growth rate: +57% p.a.). During the same period, the RFID market in the EU-15 is expected to expand from EUR 0.4 bn to EUR 4 bn (+47% p.a.).



RFID is such an intriguing business concept, as it cuts inventory and supply chain costs through its implementation. The ultimate goal is for RFID to replace barcodes. RFID allows for individual product identification, not for product line identification like barcodes. If this takes place, individual products can be read letting stores locate those items if needed. Stores can also track when items leave the store allowing them to easily replace items when one is purchased.Furthermore, shipments can be easily and quickly sorted and accepted by the receivables department. With the reader, products can be received without even opening the pallet cutting logistical needs. Obviously RFID is a great tool for the supply chain and companies wishing to better track their products and inventory.



RFID will also serve as a supply chain management tool. It will replace manual processes for tracking supplies in warehouses and at loading docks, e.g. as a crate passes by, a networked RFID portal on a loading dock can transmit information about it to a backend system. This facilitates automated creation of shipping manifests and other data, whose generation currently involves some degree of manual labor. In principle, speedy data generation by RFID means that information about, say, a crate of oranges, can reach a destination even before the oranges are loaded onto the truck. In other words, RFID is a form of automation support for the supply chain management systems of today.



Metro and Wal-Mart were the pioneers when it comes to deploying RFID tags in the supply chain. Their suppliers are increasingly attaching RFID tags to cartons and pallets, mostly with conventional bar code labels on the front so that both procedures can be used complementarily. This level is expected to become ever more widespread in logistics in the coming years.



RFID current and future trends


RFID - smart radio tags - is the keystone of the emerging 'Internet of Things' that will connect objects and places. They will create many new opportunities for software software development and other businesses alike and also benefiting society at large.



Current trends indicate that the RFID market will grow fast in the coming years. With 1.02 billion tags sold in 2006, the value of the market, including hardware, systems and services, is expected to increase by a factor of six between 2007 and 2017.



Business applications using RFID such as transport and logistics, access control, real time location, supply chain management, manufacturing and processing, agriculture, medicine and pharmaceuticals, are expected to grow strongly. FID devices will also influence Government (e.g. eGovernment, national defense and security), and consumer sectors (e.g. personal safety, sports and leisure, smart homes and smart cities). RFID and bar codes will coexist for many years, although the former technology is likely to gradually replace the latter in some sectors.



Asset tracking applications will also see the most rapid growth in the next few years and will grow disproportionately as compared to the RFID market as a whole. Interoperability across various RFID systems, companies, and countries is critical for achieving wide-scale deployment of the technology.



Conclusion


RFID, in its broadest sense, does not only refer to next-generation barcodes, but to a compact class of wireless computing devices. There is a broad spectrum of radio-frequency technologies, including more highly functional (and expensive) technologies such as Bluetooth, mobile phones, and WiFi. The future holds for applications of RFID that go far beyond mere bar-coding. A ubiquitously RFID-tagged and networked world offers a transformational extension of the World Wide Web. It will become not just a World Wide Web of data, but also a World Wide Web of things.



The world will be very different once readers and RFID tags are everywhere. In an RFID-enhanced future, the benefits would accrue not just to businesses, but also to consumers.

New York Scaffold Law Protects New York Construction Workers

There is a great deal of misinformation concerning the New York Scaffold Law. The Insurance and Business Community are wrong when they say that construction workers who are “lax about wearing safety gear” and fall from a height and are injured can hold their employer liable under New York Labor Law Section 240, the “scaffold law.” The Court of Appeals ruled definitively in /Cahill v. Triborough Bridge and Tunnel Authority/ that if a worker has been informed about and given safety equipment and fails to use it “for no good reason,” the employer cannot be held liable under the scaffold law for any resulting injuries.

Indeed, under the scaffold law, if a worker is the sole cause for whatever reason of his or her injury, the owner or general contractor cannot be held liable. An owner or general contractor can be held liable for a worker’s injuries only if their failure to provide appropriate safety equipment for work at an elevated height, like harnesses and properly constructed scaffolding, was the cause of the injuries.

The authors are also wrong when they blame rising contractor liability insurance on the scaffold law. In recent years, contractor liability insurance premiums have risen just as fast or even faster in many states – and in some countries – that have no scaffold law. In the United Kingdom, contractors report that liability insurance hikes of up 300% and more are putting many of them out of business.

Enforcement of construction safety by the U.S. Occupational Safety and Health Administration has been weak and ineffective. Without the scaffold law, the numbers of construction worker injuries and deaths in New York would surely be greater.

Common Causes of Workplace Injuries to Be Aware Of While On-The-Job

Each year millions of Americans are injured in workplace accidents. Injuries are considered work related when they either occurred at work or your job contributed to the injury in some manner. Listed below are some of the most common causes of workplace injuries.

Lifting Injuries

Injuries due to workers lifting things cause more work absences than any other workplace accident. The most common injuries reported with lifting are back injuries, muscle strain, sprains, and in some cases more serious injuries.

Falling Objects

Workers who are injured by falling objects generally are people who work in warehouses or other facilities that have some type of overhead storage. Machinery that carry piles of crates, boxes, or other work related materials, such as a hi-lo, need to have workers operate them who are properly trained. Even with all possible safety precautions in place, accidents can and do happen. Being hit with a falling object can cause head injuries, neck injuries, back injuries, and in some cases, even death.

Heavy Equipment Accidents

Many people who work at construction sites and manufacturing plants come into contact with heavy equipment on a daily basis. A piece of heavy equipment can malfunction, or be improperly maintained causing thousands of injuries every year to American workers.

Slip and Fall Accidents

Some of the most frequent workplace injuries are a direct result of a slip and fall accident. Common causes of slips and falls at work are due to slippery floors, leaks from machinery onto the floor, torn carpeting, electrical cords, and other hazards. Injuries in a slip and fall can include head injuries, back injuries, broken bones, strains and sprains, and in very severe cases, death.

Auto Accidents

You don't have to be a truck driver to be a victim of a work-related automobile accident. Millions of workers are injured each year in car accidents while traveling back and forth to work events, meetings, and other work related functions. Auto accidents are the leading cause of workplace deaths.

Catastrophic injuries such as traumatic brain injury and spinal cord injury can happen in the blink of an eye and can change your life forever. Consult with workplace injury lawyers if you have been injured in an on-the-job accident.

DBA Degree Programs Are A Secure Education Choice For Solid Employment


A company's database is the heart and soul of client information. Databases store valuable information such as contacts, sales and income, financial statements and organizational plans for management, and to lose their database means a business can no longer function. Optimal care and maintenance of databases are becoming more and more important, as old accounts bog up space or the difficulty in retrieving information slows down productivity. Not only that, security in administration is a must in our high tech world, constantly under onslaught from viruses, hacker attacks and other subversive tactics meant to steal data and destroy competition. Proper care and effective management in handling databases and their administration is vital to any successful business that relies on computer technology to function, and a DBA degree program will help you acquire the necessary skills to become an integral part of an administrative team.

A DBA degree program involves learning the skills and getting solid training to be able to design, create and implement databases for important corporations and businesses. Knowing how to administer databases is also part of the practical, hands on training you'll acquire at educational facilities competent with information technology. Some institutions will include networking knowledge in the program so that you can effectively administer databases to their maximum potential. Learning the basics of networking and its application to database administration will help you become a valuable asset for multi-million dollar corporations or international businesses. Furthermore, a DBA degree will provide you with the analytical ability to troubleshoot and improve upon existing databases or design new ones that serve companies more effectively.

Security is a large part of working with databases and no company wants to discover that its database no longer functions, wiped clean thanks to an insidious virus. The popularity and ease of use of large capacity USB drives combined with curious human nature has made them a huge tool of those who would sabotage a company's functioning and databases are perfect places to strike. Learning how to protect against such threats and knowing effective backup and replication procedures to further safeguard a company's vital information is part of being a high quality database administrator. Only training will provide you with the abilities you need to meet today's standards of safety and archiving and a DBA degree program offers that know how.

Career opportunities are widespread for those who have the backup of accreditation and degrees. The investment of time and money in going after the training you need to become a valuable asset to any company is well worth the pay off, as businesses will offer strong employment packages to those who will help them protect their important information. What's more, a proper DBA degree program from a recognized educational facility will probably have employers come looking for you, rather than you having to pound the pavement with lesser skills. Colleges and universities also usually have career placement services available, with a bank of businesses looking for skilled people. The prospects of a strong, stable professional career are very good and the job market will open up to you, thanks to your newly acquired knowledge.

Finding a good, reputable educational facility to provide you with your DBA degree program is easy, as schools have developed websites with pertinent information for what you need. What's more, many schools offer different forms of financial aid or will help you locate sources to fund your education. Searching the internet turns up plenty of facilities with programs geared specifically to the information technology industry and you'll easily find a college or university that will give you the high quality education you need to be a contender in the database administration field.

Teacher Inservice Workshops And Professional Development Courses Are What University Teacher Training Should Be

Today's teachers are prepared for yesterday's students. The truth is that college and university teacher training has been stuck in the 1950's for the past 50 years. Content and testing have remained the central focus of teacher preparation, while students' behavioral and emotional problems became the central focus of the classroom. In essence, most teacher training programs prepare teachers to work with a student who no longer exists. Contemporary teacher training gives today's teachers yesterday's tools, leaving even the most talented educator sometimes feeling ill-prepared to cope with students of the 2000s who have moved far beyond a time of bobby sox and poodle skirts to cyber sex and nipple rings.

While it is unlikely that teacher college and university training programs will change dramatically any time soon, there is no harm in speculating about what the curriculum should look like now. Subjects that are currently covered only in teacher inservice workshops, professional development seminars and education conferences, should be routinely included as a major focus of professional training for educators. When this type of practical training is left to be an optional add-on that must be sought out, located, and often paid for with a teacher's own personal funds, it becomes far less likely that most teachers will ever update their skills. I know this is true because many participants of my popular Problem Student Problem-Solver Workshops (www.youthchg.com) tell me that they have to pay for their own training, beg for days off so they can attend, and sometimes even use vacation time or forfeit their pay when their school can't or won't fund the costs.

Putting aside those concerns for the moment, in an ideal world, what might teacher training programs cover beyond content and testing? Here are the top 5 critical things that teachers are never taught but may really need right now:

1. Give Teachers Basic Juvenile Mental Health Training

More and more students have serious mental health concerns yet most teachers don't know a conduct disorder from an attachment disorder. That's like not knowing the difference between arithmetic and spelling. When teachers don't know basic mental health information, it creates the perfect conditions for safety concerns to simmer and boil throughout the school and in the classroom.

2. Offer Teachers Real-World Violence and safety Training

Schools are more out of control than ever before. School shootings, gangs and bullies can pose enormous potential safety concerns yet few teacher training programs devote extensive course work to practical, preventative methods. Using character education-- the current violence prevention method of choice today-- to stem this type of violence is naive and ineffective. While character ed can work well with many students, it will always fail with some youngsters. With some populations, such as conduct disorders (who are an estimated 11-14% of students), empathy-based approaches like character ed will actually make the situation far worse. It is an approach better suited for Archie and Jughead, not the South Park kids.

3. Show Teachers How to Teach School Skills

Years ago, families reliably taught their offspring to show respect, arrive on time, dress appropriately, and to have an appreciation for the importance of school. Now, many families cannot or will not instill those beliefs and teach those skills. If families do not teach kids how to be students, then schools must perform this function. Until then, teachers are working with untrained, unmotivated students. Teachers need to be taught how to systematically train youngsters on all aspects of school functioning from punctuality to homework management, from how to raise their hands to how often to talk in class, and so on. Motivation should be given special attention, but typical contemporary teacher training includes almost no practical focus on that today.

4. Show Teachers How to Teach Coping Skills

Because families are more likely today than years ago to be fractured, abusive, troubled and otherwise impaired, teachers need to know how to manage the problems that result when family problems come to school with students. A special focus should be given to what methods work with school refusers, withdrawn kids, work refusers, depressed students, traumatized children, and students in crisis.

5. Show Teachers How to Teach Social Skills

If a student can't sit in a chair, talk one at a time, or keep his hands to himself, it makes it almost impossible to teach that child academic content. Yet today's teachers see dozens of socially maladjusted students each day. If parents cannot or will not train their offspring to have basic social skills, teachers must pick up the slack. A child who can sit in his chair, talk one at a time, and keep his hands to himself, is far more likely to be a teachable student. There are no shortcuts around the serious social skill deficiencies that educators cope with today. Until Susie can acquire at least minimal social skills, educating her may be impossible.

It is way past time to drag teacher training into the new millennium. If you are a teacher struggling to make sense out of your troubled, challenging students, the problem isn't you. The problem is that your professional training fits students who walked your corridors a whopping half century ago. If you want to learn the practical, updated, more effective methods that they didn't teach you in college, your only option now is to find an inservice course, workshop or professional development seminar that can upgrade your skills to fit contemporary youth.

Now You Can Keep Your Valuables Safe


The best place to hide anything is in plain sight! For this reason, diversion safes are the perfect place in which to hide your valuables. The Chicago Crime Commission has said that a burglar spends an average of 8 minutes in the victim's home. They are looking for easy items they can grab and then exit within a very short timeframe.

So, put the odds in your favor with hidden safes. With a hidden safe or a diversion safe, you can increase your odds of keeping your valuables and treasured items protected! Simply hide your valuables inside the diversion safe which is made from an otherwise ordinary object and put it in it's rightful place. No one will notice they are there. A regular object that is placed in a conspicuous location and doesn't look out of place, can fool burglars.

How do diversion safes or hidden safes work? The diversion safes are disguised as such things as genuine personal care items, genuine well-known household products and genuine food containers. Examples of these are a can safe, wall outlet, salt shaker, salad dressing jar, book, candle, flower pot diversion safe, beer and soda safe, etc. Some diversion safes also come in different titles and different brands. They are constructed to be undistinguishable from the genuine product and are even weighted to feel full. They look and feel like the real products, right down to the bar codes.

These hidden safes, once spread about your home, make it much harder to keep your valuables or money from being found by burglars and even friends and relatives who may have sticky fingers.

One of the biggest benefits of these safes is cost. The use of hidden safes in recommended hiding spots is an inexpensive alternative to the more highly priced safes you can buy for a whole bunch more money. Prices generally range from $8.95 to $20.00 which is way less than most conventional fireproof safes. Determined burglars can easily remove very heavy safes, even ones that are bolted down to the floor.

Help yourself and not the burglar; hide your valuables and treasured items in plain sight!

Forklift Safety Tip #2 - "Do Seatbelts Have To Be Worn?"

Forklift safety Tip #2 - "Do Seatbelts Have To Be Worn?"



The simple answer is yes.



You see, most new sit down type (counter balanced) forklifts come fitted with a seat belt and it is mandatory that they are worn. This said, it's common practice at many companies for operators to overlook wearing the belts and they're very rarely used.



In fact, quite often when we go into companies to do training, the supervisors, managers, and even the operators themselves don't realise that the forklifts have seatbelts.



Do All Forklifts Have Seatbelts?



Some forklifts have seatbelts and others don't, depending on the make and model you purchase. Basically, if it came standard from the manufacturer with a seatbelt then it must be worn. If it didn't come fitted with one from new, then none is needed.



The belts are only ever a lap sash type so they don't restrict the drivers from turning their shoulders to look backwards. Their main purpose is to keep the operator in the seat in case of a role over. When a forklift tips over sideways, one of the greatest risks is that the operator can end up under the machine so the belts are there to prevent this.



Why Don't Operators Like to Wear Them?



It is obviously a major pain for operators to put the belts on and off when ever they use the forklift and this is the main reason they're not usually worn. If an operator were to jump on and off of the forklift 30 times a day then you can imagine the inconvenience the belt can cause.



That's why many small to medium sized companies choose to turn a blind eye to the seatbelts and don't enforce the wearing of them.



The risk to you however is that if one of the forklifts happens to roll over and the driver isn't wearing the belt, they won't be covered by your company's insurance. The company will also have to answer to WorkCover/WorkSafe etc (depending which state you're in) for not ensuring that belts where being worn.



Drivers themselves can also incur personal fines from WorkCover inspectors for not wearing belts.



So What's The Solution?



More and more large companies are starting to strictly enforce the wearing of seatbelts. Some have even gone as far as having the forklifts wired up in such a way that they won't start or run unless the seatbelt is on.



Lets face it, putting a seatbelt on and off isn't really going to slow your drivers up that much. I strongly recommend taking a tough stance with your staff and enforce the wearing of seatbelts.



You're going to get some whinging and complaining from certain staff members at first but take it from me, putting up with a little whining is far better than having to call someones wife or husband after a serious workplace accident.



If you have any question relating to this or any other matter, please feel free to call me on 0416 209 798 or email me nathan@directforkliftsales.com.au
