I’ve had my iPhone for over a year now, and I love the apps on the phone. There’s no better way for me to pass the time now, whether I’m riding on the train or waiting for an appointment to begin.

The games continue to improve, as updates and new versions are constantly released. Some of them are incredibly addicting. I’ve never paid money for an iPhone app, so the ones that I mention here are all free games that you’ll have no problem downloading and enjoying if you have the phone. Let’s take a look at my top three.

If you’ve never played Paper Toss, I would recommend downloading it. It’s a free game, so you have nothing to lose by trying it out. All you have to do is take a crumpled piece of paper and throw it into a garbage across the room.

The best part about this game is the enemy that stands in your way. The enemy here is an office fan that blows your paper in different directions. Since you can see its speed in advance, it becomes a challenge to accurately get the throw right.

Have you ever played that game in a bar where you have to touch the differences between pictures? If you have, you’ll probably enjoy ESPN’s game, which is just like this. It’s called Camera Man and you’ll basically be doing the same thing, only on your phone.

This game might keep me occupied more than any other. Sometimes I’ll sit down for hours at a time with this game.

3. Scramble. This game is just like Boggle, only you can play it online against over 100 people all at once. I love the idea of competing against others, which makes this game extremely addicting once you take the pride factor into consideration.

Try any of these games out. Based on their overall popularity, I have a feeling you’ll enjoy them very much.

Mechanical energy is an area of science that is making strides every day. The study of how actuators produce mechanical motion by converting various forms of energy into mechanical energy is a source of great exploration. Science finds new ways to make use of actuators every day including for medical purposes. Many scientists believe that the more they study these seemingly simple machines, the more they will discover ways of helping mankind.

The way in which a linear actuator works is that there is a motor that rotates a drive screw using a synchronous timing belt drive. Some linear actuators can also use a worm gear drive or direct drive. Which ever the choice, the turning of the screw pushes a drive nut along the screw, which in turn pushes the rod out and rotating the screw in the opposite direction will retract the rod. According to the Association of Sciences, the drive screw is either an ACME or ball thread or is belt-driven which is what gives the machine its motion. A cover tube protects the screw nut from environmental elements and contamination thus allowing for the machines use continually without the chance of it getting gummed up. Radial thrust bearings permit the screw to rotate freely under loaded conditions and gives the linear actuator its strength.

Linear actuators usually serve as part of motion control systems. These days most are run by computers. Control systems, a device that you find linear actuators in, move or control objects. This is made possible by the actuators.

Actuators are used heavily in robotics and industrial robotics. The energy used to power them can come from a variety of sources such as: pneumatic, electrical, mechanical, and hydraulic.

Linear motion is when an object moves in a straight line. This is the basic concept that drives the linear actuator. One has to stop and consider when choosing a linear actuator which type they need to fit the purpose of their project. Some things to keep in mind are the speed, stroke length and load rating of the actuator. Programmability of the actuator is also a factor especially when the application will be one that requires specialized detail. A linear actuator can be used in just about any forum. Ask yourself some questions when attempting to choose the right one for your project such as are there particular safety mechanisms required, environmental concerns to be addressed or space issues?

Television technology has certainly evolved from the old models of the 60′s and 70′s. In fact, today Plasma TV’s have slim flat panel designs which produce realistic pictures with high contrast ratios and vibrant colors. Although developed in the 60′s, the technology behind plasmas did not gain mainstream acceptance until the late 1990′s.

Plasma technology was first developed for computer monitor systems in the early 1960′s and the first companies to bring this technology to the retail market were Fujitsu and Phillips. Moreover, the first units for sale in the US were more of a status symbol since they debuted with a hefty price tag of over $10,000. However, today’s refined production techniques allow plasma units to retail for a much lower and accessible price.

A plasma TV is a specific type of flat panel television set that uses numerous tiny cells sandwiched between two screens. The cells contain a mixture of noble gasses that are turned into a plasma gas when subjected to an electric current. Moreover, the phosphors in the gas excite to produce light and the whole plasma unit is usually less than 4 inches thick and 32 inches or larger. Manufacturers have yet to produce a cost effective plasma TV that is less than 32 inches.

Color in a plasma TV is produced by coating each of the individual cells with a material called phosphors. When the gases are converted to plasma they produce photons which in turn excite the phosphors to generate color.

The picture on a regular television set is made up of thousands of individual pixels and it is no different for plasma TV’s. Every pixel on a plasma unit is subdivided into three sub pixels with a coating of either a red, green or blue colored phosphor. The three colors are used in traditional cathode ray tube televisions which is why a plasma TV can closely replicate the colors of older models. Blending red, green and blue together also allows the plasma system to create just about any tone imaginable.

Pulse-width modulation regulates the intensity of the phosphor coating on each sub pixel and it works by controlling the amount of current that flows through the thousands of individual cells. Moreover, internal controls activate the pulses at a rate of thousands of times per second and the varying intensity allow for the incredibly sharp and vivid colors that are associated with plasma televisions.

With respect to contrast ratio, plasma TV’s typically offer the highest ratio in comparison to LCD and DLP televisions. Contrast ratio is an important feature in determining the overall quality of the picture because it is a measure of the ratio between the highest white and the darkest black.

Plasma television has come a long way since its inceptions in a California laboratory over thirty-five years ago. When plasma TV’s first hit the retail market the initial cost made it more of a status symbol rather than a fixture in most households. However, as demand grew production methods were eventually refined to make these devices much affordable to the masses.

Retirement comes with a benefit and a drawback: more time and less money. The discovery of the Internet has changed the way we lead our lives. We can pay our bills online, go shopping online, do our banking online, and even make a date online!

It is important too for the retired person to sign up with an online stock broking firm that has been around for a while.

Sure, online stock trading is a wonderful thing for the retired – but it is not for everyone, the impetuous can lose money quickly. Think long and hard before you decide to opt for buy stock online, and be sure that you really know what you are doing!

Therefore, in summary, retirees can use their newly-found free time to investigate the stock market free by finding leads in newspapers, magazines and news programmes. These leads can then be followed up by online research using a free online stock investing account.

These hunches can then be tracked using a dummy or trial portfolio, sometimes called a ‘watch list’. After you have gained sufficient confidence, you can go ‘live’ by opening an active online stock investing account.
