Global Industrial Robotics Market to Reach 204 Thousand Units by 2017, According to New Report by Global Industry Analysts, Inc.

San Jose, CA (PRWEB) February 27, 2012

Follow us on LinkedIn – Robotic technologies have undergone sea changes, over the decades, goaded on by the need to automate the workforce and achieve zero-error tasks/operations. Incremental technology developments in chip design have transformed robots into smaller, more intelligent and less inexpensive marvels of mechatronic engineering. Convergence of robotics with cognitive science, artificial intelligence, and information technology is now helping bring closer to reality multi-dimensional intelligent robots. Robotics today is an established manufacturing technology given its reliability in enabling an automated workflow environment and capability in serving a variety of applications in large, small and medium enterprises. Growing acceptance of robotics by the workforce and change in employee perception on the use of robots, from what was earlier perceived to be a threat to their employment, to now being looked at as a key facilitating technology, has increased the adoption of robots. The manufacturing industry therefore remains a major end-use market for industrial robots. Within this sector, automotive manufacturing is a key application area. Robots have made rapid strides in the automotive manufacturing sector over the years, contributing significantly towards increasing the efficiency and productivity of automotive manufacturing, especially in application areas such as painting, welding and parts placement.

Against this backdrop, the market for industrial robotics remains sensitive to manufacturing/engineering activities and industrial production. Given the widespread diffusion of industrial robots, especially assembly line robots, robot investments in large companies are already a part of the capital structure. Being a capital expenditure, market for industrial robots is also dependent on the health of the capital goods sector. Capital rationalization processes, like the ones witnessed during the 2007-2009 recession, therefore tend to negatively impact robot installations rates in industries, such as, automotive, consumer goods, semi-conductor & electronics and rubber & plastic, among others.

EUs industrial sentiment currently remains torn between optimism and pessimism given the mixed signals emanating from the volatile manufacturing data in Spain and Italy and the encouraging industrial performance in Germany. Bearish market sentiments however indicate that an escalation in the euro crisis could precipitate a slowdown in global business in the event of the debt crisis spreading to the banking system in the United States. This in turn could cripple interbank lending activities. Also the shift from fiscal government stimulus to anti-crisis austerity and spending cuts as a measure to tame the towering public debt scenario can likely impact capital expenditure in manufacturing industries in debt affected economies by limiting borrowing and reducing investments in capital goods. Reduced ability of the government to fund capital expenditure can impact both domestic and foreign financed projects thus indirectly influencing spending on factory related capital equipment including industrial robots.

Despite the challenges ahead and uncertainties over the continued economic stability in Europe and in the United States, most market indicators for the immediate-term future feature a largely positive outlook for the manufacturing industry in the year 2012. Manufacturing production which continued to recover from 2010 through 2011 is expected to continue into the year 2012. For instance, in Germany industrial/manufacturing output is holding well as indicated by the country’s yet strong export market, a key reason for the country’s superior handling of its debt crisis in comparison with Greece, Portugal, Spain and Italy. Although industrial output in developing countries is expected to outstrip the same in developed countries, average annual gains witnessed in these countries nevertheless continues to remain encouraging. Given the yet unclear signs of a possible decline in industrial production either in Europe or in the international market, factory investments are expected to lead the rebound in capital goods.

While lethargy in industrial automation, particularly in US, Europe and Japan, continues to stabilize growth patterns in these countries, increased adoption of robotics will drive strong gains in the developing countries. China especially is expected to witness the maximum growth driven by rising labor costs and issues related to manufacturing efficiency and safety. Also, the growing clout of Chinese automakers in the global market is creating strong demand for robots in the domestic auto industry. Given that China remains an export oriented economy, increased spending by the Chinese government to ensure development of domestic manufacturing processes is generating strong demand for robots in packaging and palletizing applications in addition to automotive applications.

Demographic changes over the next decade, such as, aging and retirement of the current workforce will create large gaps in the workforce thus creating demand for automation and industrial robotics. In addition, shortages and exorbitantly high cost of labor for risky jobs will further unleash a search for electronic alternatives as replacements for human personnel. Unlike popular perception that labor shortages are pronounced only in the developed countries, China interestingly of late has been witnessing massive labor shortages in dangerous construction sectors, and at factories with appalling work conditions. Expansion in end-use applications is also poised to drive growth in the marketplace in the upcoming years. For instance, advantages of automation, which hitherto was focused on and reaped by the automobile industry, will now witness other industrial sectors, such as, plastics & rubber and food and beverage handling and processing, wax in popularity as lucrative end-users of robotics in parallel with the automotive industry.

As stated by the new market research report on Industrial Robotics, Europe represents the largest market worldwide. Driven by continuous shifting of manufacturing bases into Asia-Pacific, the region is forecast to witness the fastest growth, trailing a projected CAGR of 21.4% over the analysis period. Growth in the world market in general will be driven by technology advancements and the ensuing commercialization of new-age industrial robots with advanced capabilities and features. This in turn will present a range of possibilities and capabilities that were hitherto unimaginable thus attracting tremendous opportunities in diverse industry segments. Use of robotics in assembly line production is poised to score the maximum gains during the analysis period.

Major players in the marketplace include ABB Limited, Adept Technology, Inc., Denso Wave Incorporated, Evolution Robotics, Inc., FANUC Corporation, iRobot Corporation, Kawasaki Robotics (USA) Inc, KUKA Roboter GmbH, Panasonic Welding Systems Co., Ltd., Nachi-Fujikoshi Corporation, Rockwell Automation Inc, ST Robotics, STAUBLI Corporation, YASKAWA Electric Corporation, among others.

Electronic Waveform Lab Releases a Major Upgrade of its Flagship Pain Management and Rehabilitation Product: The H-Wave® Instrument

The H-Wave® Instrument

Huntington Beach, CA (PRWEB) February 16, 2012

The device is used in clinics and can also be prescribed for home use where patients can treat themselves. The company first introduced the electrotherapy device in 1981. Since that time H-Wave® has built its reputation as one of the most unique and effective rehabilitative treatments in the country. With the growing concern of abuse and side effects associated with prescription drug use an effective alternative such as H-Wave has been growing in popularity. Published research has shown that the technology of H-Wave® represents a paradigm shift in electro-therapeutic treatment and numerous objective benefits have been observed.

The newest generation of the H-Wave® (Model H4) Instrument is smaller, lighter, and more durable than previous models. It is also easier to use, improving compliance. The new device can be set into pre-set mode in which the patient only has access to the frequencies/modes that they need. For clinicians or advanced users, the device can be used in Manual Mode allowing users to access a larger range of frequencies/modes. A new digital timer also allows for better tracking of treatment times. The unit boasts larger and easier to control dials (especially for those that might have hand injuries/weakness).

The new “No Load Trip” feature turns off the device and alerts the user when a lead/electrode connection is broken or insecure. This eliminates the possibility of a wire unplugging from an electrode and directly contacting a patent’s skin and causing discomfort.

The unit’s battery life has increased to 10+ hours, more than double the life of the previous model. The unit also carries an improved charging indicator which prevents overcharging or hurt internal battery pack. Also, a more environmentally friendly NiMh rechargeable battery pack can be replaced by the user without sending the device in for repair.

The unit has proven its effectiveness in professional sports and clinical use. According to Gary Vitti, the Head Athletic Trainer for the Los Angeles Lakers, “I just finished my thirteenth year with the Los Angeles Lakers and I wanted you to know the H-Wave® continues to be my electro-modality of choice for pain” Joseph DiGivonna of NovaCare Rehabilitation also writes “I have used your device on approximately 100 patients over the course of the past 18 months. I have personally thought it to be the single most effective modality in my arsenal.” The first H-Wave H4 sold was to the 2010-2011 Superbowl Champion Green Bay Packers who own more than 20 portable H-Wave devices that are in constant use.

The H-Wave® Instrument now retails for $ 3,300, a moderate increase over the previous model. The unit can also be rented for $ 330 per month with rental applying towards the purchase price. Electronic Waveform Laboratories continues to offer a full money back guarantee on the new unit.

Article by Kingston Y. amadan

When most people think of electronics, they think of audiovisual devices like cameras, computers, TVs, and recorders. Spy electronics also encompass all of things. The main difference is that while all of the above items are mainly used for entertainment purposes, spy electronics are meant to be used in surveillance. These electronics can be very technologically advanced, and some of them can be so well disguised that others do not even realize that they are being watched or listened to.

Spy electronics are necessary to make the whole surveillance profession work. After all, if you do not have recording equipment, or equipment to recover the recordings, then it is no good. You cannot perform effective surveillance. Additionally, electronics in places like command centers and control rooms are what coordinate the efforts of individual pieces of electronic equipment and they also direct the surveillance efforts. In today’s world, the professional needs electronics to be an effective bounty hunter or private investigator.

Spy electronics are not only necessary for people like PIs and bounty hunters. The military makes extensive use of these things. Indeed, their electronic spy devices include things like unmanned spy planes and prototypes for other high tech equipment. Police and government intelligence agencies also make heavy use of spy electronics. Wiretaps and the equipment to listen into fall into the category of electronics. Other forms of surveillance, such as cameras and other listening devices are also necessary.

Other spy electronics that also perform useful functions include TVs and other screens that display information and computers that keep track of tracking devices and maps. Additionally, computers can direct remote cameras to find new angles and they can also record information and display it a way that is more useful to the user. There is no doubt that computers are becoming very important pieces of electronic equipment that can be used for surveillance purposes.

Without spy electronics the possibilities for evidence and intelligence gathering. Whether for national security or for your divorce case would be much more limited. Technology has made it possible with a variety of advancements to find out just about anything that you might need to know to help you maintain your quality of life. And it is all made possible with information gathered and analyzed with the aid of spy electronics.

A consumer electronics company sells 6.7 million MP3 players per month at a price of $ 100 apiece; when the price is lowered to $ 80, the company sells 10.2 million players per month. How many MP3 players can the company expect to sell per month at a price of $ 75?

Best answer:

Answer by Stephen P
Since there’s no other information given, you might as well assume that demand is given by a linear function.

Let D be the demand and P the price. Then D(100) = 6.7 and D(80) = 10.2. The slope is (10.2-6.7)/(80-100) = -0.175. So using the point-slope formula, the line is
D(P) = -0.175 (P-80) + 10.2.

When P=75, the demand is
D(75) = -0.175 (-5) + 10.2 = 11.075 million.

Electronic Typewriters – Tips When Purchasing One

 With the many functions that computers and computer software now serve, many people don’t feel the need for a typewriter. However, electronic typewriters are still widely used in the workplace and serve many functions, particularly in offices.  While the computers of today can do almost everything but vacuum your floors, electronic typewriters are still the chosen piece of equipment for printed forms, envelopes, carbon copies, labels as well as many types of checks in financial institutions.

 What Type of Typewriter Do You Need?

 When looking for a typewriter, you’ll find there are manual, portable and electronic typewriters available with some of the most known brands being Royal, Brother, Smith-Corona, IBM to name just a few. Most business places choose electronic typewriters for their basic office needs. Electronic typewriters can be purchased online as well as in most office supply stores. Because of the wide use of computers and word processing programs, electronic typewriters can now be purchased for very affordable prices.

]]>

 When choosing electronic typewriters, the most important thing is to keep in mind what your needs are going to be as well as the budget you have or want to work within. If you don’t have plans for using the electronic typewriter often, you aren’t going to need a lot of extra functions but if it will be used regularly, you may need some of the extra features. Some of the things you may need to consider when deciding what type of electronic typewriter you need include the paper width you’ll be using, the amount of projects you’ll be doing, what type of projects they’ll be, if you’ll need a lot of different fonts and if you’ll need to make corrections on your documents.

 Features To Look For in Your Electronic Typewriter

 With those factors in mind, you’re ready to go shopping for a good electronic typewriter. If you shop online you’ll find more electronic typewriters available but won’t have the one-to-one contact with a salesperson that can explain each feature of electronic typewriters. “Window shopping” online will be able to give you a good idea of what to expect as far as features per price when you do begin shopping for electronic typewriters. However, here are some of the most common things to look for when you’re finally ready to purchase your electronic typewriter.

 Correction Features: Although we like to think we’re not going to make mistakes, they do happen so better look at electronic typewriters prepared to make corrections for you. Pitch Selection & Font Choices: It’s better to have more fonts on your electronic typewriter than you need than less and extra fonts generally come with most electronic typewriters. Usually 10 point and 12 point pitch is common in most electronic typewriters and are the most commonly used. Page Width: Occasionally you may be doing wider documents so it’s best to be prepared. Memory: Many of the newer electronic typewriters have memory feature and this is an excellent feature and worth having, especially if you’ll be typing a lot of repetitive documents with minimal changes.

Dirty Electronics : Solder a Score @ ICA London

Dirty Electronics : Solder a Score @ ICA London 16th to 20th Feb 2011.

The composer and instrument maker John Richards takes up temporary residence in the gallery with Solder and Score, a unique participation opportunity for visitors to the ICA. Over the course of five days workshop attendees will build a large patchwork quilt-like instrument and co-write a musical score with John, culminating in a group performance and auction. Referring to his process as Dirty Electronics, Richards conjures electronic phenomena at odds to those found in today’s mass produced digital culture and utilises characteristics such as designer trash, hand-made, ready-made, hacked, bent, fedback and kitsch in the process.
For Live Weekends: Notation and Interpretation, the proposed workshops will immerse attendees in the interplay between process and performance beginning on the workbench, co-devising the modules that will form the ‘instrument’ and then extending onto the stage. The workshops will be informed by a musical score written especially for Dirty Electronics by sound artist Nicholas Bullen (founder member of Napalm Death and Scorn and a frequent collaborator with artist Mark Titchner).

The amount of electronic waste that we produce each year is growing at an ever increasing rate, with the rise of cheap consumer electronics and yearly advances in technology, coupled with our overall desire and demand for the latest and greatest electronic device that is going to make our lives so much better using it, than the previous version. Well, what happens to the old, the broken and thrown out electronics? It becomes electronic waste, normally in the past, this was like most other types of waste and was used as land fill, unknowingly or knowingly many of these devices included materials such as lead, mercury, sulphur or cadmium to name a few, that are considered hazardous, or dangerous, so putting this material into landfills by the thousands of tonne loads was causing un-repairable damage to the earth they were put in.

Human conscience however has changed over the decades, especially when it was seen that there was the possibility of making a dollar or two, so with that came the era of recycling. It was realized that materials used in electronic devices such as gold, silver, copper, tin, aluminum, iron, nickel and plastics just to name a few, could be processed and removed from electronic waste and sold to be used in many different ways, this is the modern day gold miner of sorts. Now there is a drive on throughout the world and the United States to recycle electronic waste, there has been many laws passed throughout the United States that require electronic waste to be processed differently to normal waste to stop it from getting processed into landfills, this in turn boosts the recycling drive.

90% (ninety percent) of electronic waste in the United States is sold and exported to China and Nigeria, which makes these countries look like the modern gold miners and protectors of earth, but is that the truth?

There is currently a silent battle going on in the world and it’s the world of counterfeit electronic components, the battle is raging between the counterfeiters who are successfully able to get their poor quality products into supply chains and the electronic component suppliers who have to keep up to date with who is supplying them their components and having a strict quality control system to find and stop the flow of counterfeited products from getting into the supply market and causing problems when used in manufacturing devices.

One of the biggest counterfeiting production types is harvesting. This is the process of removing components from electronic waste, rebranding or remarking the components and selling them off as new. One of the biggest producers of counterfeited electronic components is China.

Let’s now look at the equation we have The United States whom sells 90% of its electronic waste to one of the biggest producers of counterfeited electronic components who uses one of the largest counterfeiting production types, the harvesting of components from electronic waste.

Is selling most of the electronic waste produced in the United States to China such a good idea?

Very, very expensive. The cost I believe would be the highest, you dont even mention, which is the Research and Development of all the electronics that would be needed. Plus licensing costs of parts you get from other companies, costs to buy all the required parts, costs to manufacture, costs of factories to produce, etc. Very expensive.

What do you think? Answer below!

An electric current is usually thought of as a flow of electrons. When two ends of a battery are connected to each other by means of a metal wire, electrons flow out of one end (electrode or pole) of the battery, through the wire, and into the opposite end of the battery. An electric current can also be thought of as a flow of positive “holes.” A “hole” in this sense is a region of space where an electron might normally be found but does not exist. The absence of the electron’s negative charge can be thought of as creating a positively charged hole. In some cases, an electric current can also consist of a flow of positively charge particles known as cations. A cation is simply an atom or group of atoms carrying a positive charge.

The ampere (amp) is used to measure the amount of current flow. The unit was named for French mathematician and physicist André Marie Ampère who founded the modern study of electric currents. The ampere is defined in terms of the number of electrons that pass any given point in some unit of time. Since electric charge is measured in coulombs, an exact definition for the ampere is the number of coulombs that pass a given point each second.  In order for an electric current to flow, a number of conditions must be met. First, a potential difference must exist between two points. The term potential difference (or voltage) means that the force created by a group of electrons in one place is greater than the force of electrons in some other place. The greater force pushes electrons away from the first place and toward the second place.

Potential differences usually do not occur in nature. In most cases, the distribution of electrons in the world around us is fairly even. Scientists have invented certain kinds of devices, however, in which electrons can be accumulated, producing a potential difference. A battery, for example, is nothing other than a device for producing large masses of electrons at one electrode (a point from which electric current is sent or received) and a deficiency of electrons at the other electrode. This difference accounts for the battery’s ability to generate a potential difference, or voltage.

A second condition needed in order for a current to flow is a path along which electrons can travel. Some materials are able to provide such a path, and others are not. Materials that permit a flow of electric current are said to be conductors. Those that block the flow of electric current are called nonconductors or insulators. The metal wire connecting the two battery poles in the example cited earlier provides a path for the movement of electrons from one pole of the battery to the other. The conductivity of materials is an intrinsic (or natural) property based on their resistance to the movement of electrons. The electrons in some materials are tied up in chemical bonds and are not available to conduct an electric current. In other materials, large numbers of electrons are free to move, and they transmit a flow of electrons easily.

Electrical resistance (or resistivity) is measured in a unit known as the ohm (Ω). The unit was named in honor of German physicist Georg Simon Ohm, the first person to express the laws of electrical conductivity. The opposite of resistance is conductance, a property that is measured in a unit called the mho (ohm spelled backwards). The resistance of a piece of wire used in an electric circuit depends on three factors: the length of the wire, its cross-sectional area, and the resistivity of the material of which the wire is made of. To understand the effects of electrical resistance, we may think of water flowing through a hose. The amount of water that flows through the hose is similar to the current in the wire. Just as more water can pass through a fat fire hose than a skinny garden hose, a fat metal wire can carry more current than a skinny metal wire. For the wire, the larger is the cross-sectional area, the lower is its resistance and the smaller the cross-sectional area is, the greater will be its resistance.

A similar comparison can be made with regard to length. It is harder for water to flow through a long hose simply because it has to travel farther. Similarly, it is harder for current to travel through a long wire than through a short wire. Resistivity is a property of the material of which the wire itself is made and differs from material to material. Let us imagine filling of a fire hose with molasses rather than water. The molasses will flow more slowly simply because of its viscosity (stickiness or resistance to flow). Similarly, electric current flows through some metals (such as lead) with more difficulty than it does through other metals (such as silver).

In most cases, the path followed by an electric current is known as an electric circuit. At a minimum, a circuit consists of (1) a source of electrons (such as a battery) that will provide a potential difference and (2) a pathway on which the electrons can travel (such as a metal wire). Here we may recall that potential difference (or voltage) refers to a greater force of electrons in one place than in another; that greater force propels electrons toward the place with the lower force.

For any practical (or useful) application, a current also requires (3) an appliance whose operation depends on a flow of electric current. Such appliances include electric clocks, toasters, radios, television sets, and various types of electric motors. In many cases, electric circuits also contain (4) some kind of meter that shows the amount of electric current or potential difference in a circuit. Finally, a circuit is likely to include (5) various devices to control the flow of electric current, such as rectifiers, transformers, condensers, and circuit breakers. Appliances may be placed into an electric circuit in one of two ways. In a series circuit, current flows through the appliances one after the other. In a parallel circuit, an incoming current is divided up and sent through each separate circuit independently.

An important advantage of parallel circuits is their resistance to damage. Suppose that any one of the appliances in a series circuit is damaged so that current cannot flow through it. This breakdown prevents current from flowing in any of the appliances. Such a problem does not arise with a parallel circuit. If any one of the appliances in a parallel circuit fails, current still continues to flow through the other appliances in the circuit. The principle and mathematical relationship governing the flow of electric current in a circuit was discovered by Ohm in 1827. Ohm’s law states that the amount of current (i) in a circuit is directly related to the potential difference (V) and inversely related to the resistance (r) in the circuit. In other words, i = V/r. What Ohm’s law says is that an increase in potential difference or a decrease in resistance produces an increase in current flow. Conversely, a decrease in potential difference or an increase in resistance produces a decrease in current flow. The more complicated an electric circuit becomes; the more difficult it becomes to apply Ohm’s law.

The field of electrical engineering is burdened with a strange problem that developed more than 200 years ago. When scientists first studied the flow of electric current from one place to another, they believed that the flow was produced by the motion of tiny particles. Since the electron had not yet been discovered, they assumed that those particles carried a positive charge. Today we know otherwise. Electric current is a flow of negatively charged particles: electrons. But the custom of showing electric current as positive has been around for a long time, and it is still widely used. For that reason, it is not uncommon to see electric current represented as a flow of positive charges, even though we have known better for a long time.

The type of electric current described thus far is direct current (DC current). Direct current always involves the movement of electrons from a region of high negative charge to one of lower negative charge. The electric current produced by batteries is direct current. Interestingly enough, the vast majority of electric current used for practical purposes is alternating current (AC current). Alternating current is current that changes the direction in which it flows very quickly. In North America, for example, commercial electrical power lines operate at a frequency of 60 hertz. (Hertz is the unit of frequency.) In a 60 hertz line, the current changes its direction 60 times every second. Other types of alternating current also are used widely. Outside of North America, a 50 hertz power line is more common. And in airplanes, alternating current is usually rated at 400 hertz.
