Take Care of Your Li-On Battery

Lithium-Ion batteries have a finite life; they slowly degrade from the day they are first made. The life of the battery will depend upon how you charge and discharge the battery and the temperature at which the battery is kept. A manufacturer will rate a Notebook battery to the point where it holds 50% of its original capacity. At this point you should consider replacing the battery.

  The energy is stored in these batteries through the movement of lithium ions. Lithium is the third lightest element, giving a substantial saving in weight compared to batteries using much heavier metals. However, the bulk of the electrodes are effectively "housing" for the ions and add weight, and in addition "dead weight" from the electrolyte, current collectors, casing, electronics and conductivity additives reduce the charge per unit mass to little more than that of other rechargeable batteries. The forte of the Li-ion chemistry is the high open circuit voltage in comparison to aqueous batteries (such as lead acid, nickel metal hybride and nickel cadmium).

  Transport lithium batteries with care. Because of the potential for short circuit and rapid discharge causing explosion, the air transportation of lithium batteries is strictly regulated. Any battery not installed in an electronic device may not be transported in either checked or carry-on luggage.

  Remember that the battery half-lifeis rated for a certain total number of charge/discharge cycles (see your User Manual or Quick Start Guide for the rating). For example, a battery that is rated for 3 hours and 500 charge/discharge cycles will still be considered as within specification, even if it only lasts for 1 hour 45 minutes after 500 charge/discharge cycles.

  Always ensure the battery is recharged as soon as possible after it becomes fully discharged. A battery will be permanently damaged if left for an extended length of time in a fully discharged state.

  Heat is the worst enemy of a battery. Allow plenty of air to circulate around the Notebook/Tablet PC, so that the battery is kept as cool as possible when charging and also when in use. If provided, use the integrated 'legs' under the Notebook to raise the notebook and improve air circulation.

  Do Not - Expose the battery to excessive heat or cold (i.e. outside the range of 10-35 degrees Centigrade ambient).

Do Not - Store the battery in a fully charged state (store batteries with about 50% charge).

 Do Not - Allow a nearly flat battery to be unused for more than a month or so. The battery will slowly discharge until it becomes fully discharged and this will permanently damage the battery cells.

Bose Cinemate GS Series II Review

If you hear or read about Bose'e Room filling Sound, they are talking about a room that is no larger than 12'x12'. I have the Cinemate in a 20X30 and you can barely hear it at the back of the room unless you turn it up so loud that you can't be in the fromt of the room. I wanted a 3D sound without a bunch of wires and speakers crowding the room and wires everywhere to trip over. Bose told me that they don't make a 2.1 system for a larger room. The closest they get is a Lifestyle System tht is three times the cost of the Bose Cinemate GS Series II.

Also there is no volume indicator on the Bose Cinemate , so you must guess at the setting or learn to count the number of off and on times the power light blinks( this is the volume change indicator. The Subwoofer at least has a volume control on it so you can get the ballance between base and voice to your liking. As far as the 3D effects, I can't hear them. ( they are supposed to be better in the Lifestyle models, but I wasn't going to lay down more money on a 2.1 systen than I paid for the top of the line LG 3D TV.

So unless you are willing to have speakers all around your room, you need to get used to the base rich sterio sound of the Cinemate. I have tried three different brands (one of them was Sony's new 550) so far and none give as good of room filling sound with just the front speakers and a sub woofer as my old TV which was a Sony KD series 60" lcd rear projection with high quality built in speakers way out to the side of the screen.

If you are going to spend the money for the Bose Cinemate GS Series II, you might as well try the Yamaha 5100 sound bar system with an external Subwoofer. In any event, do like I did and work with a retailer thet guarantees sadisfaction or a money back or exchange policy.

The 3D sound from just the front speakers and a sub is a lot harder to get than the retailers lead you to believe, at least this is what I am going through with a larger room with a Cathederal Celing.

Using Electric Linear Actuators in Wind Turbine Systems

Electric linear actuator is an ideal choice for wind turbine systems these days. The devices play an increasingly important role of meeting performance requirements and thus, enhance their efficiency. More and more designers today are turning to this type of actuator in order to control significant functions such as blade pitch control, rotor locking and blade locking. Let us discuss about their major role in detail:

Assists in pitch control

This is the most important role of electric linear actuators that make them ideal for wind turbine systems. Pitch control is indeed the most significant aspect of wind turbine operation. If the wind lifts up driving the rotor quicker, the blades are slightly pitched out. This brings the speed back down. On the other hand, if the wind falls, the blades can be pitched back into the wind. Pitch control systems are very complicated. Electric actuators play an important role of delivering the small changes in pitch. Apart from this, the devices also provide a blade locking function for locking the blade in position after it has been rotated. 

Improving the ergonomics of wind turbines

These days, designers are also making use of these devices for the purpose of improving the ergonomics of wind turbines.

But what exactly are the features that make electric linear actuators a preferred choice for wind turbine systems? Some of the important features associated with the devices have been listed below. These include:

Smaller size

The fact that the devices are smaller than their hydraulic counterparts helps in the optimization of overall space requirements.

Easy installation

It is very easy to install these devices. Maintenance requirements are also less. There is no need to change the fluids and any possibility of leaks. In addition to this, the devices are extremely easy to control.

High performance in extreme environmental conditions

The devices are capable enough to perform well in extreme environmental conditions in remote locations.  

Additional features

Other important features that have resulted in increasing use of these devices in wind turbine applications is their simple design, light weight, compact design, light weight and cost-efficiency.

All these features together make the electric linear actuators an ideal choice for wind turbine system.

Their increasingly important role in these systems has been helping individuals to a large extent.

LED Club Lights For A Totally Different Ambience

Presently the new and the in trend with nightclubs, bars and discos is the LED lighting. The LED club lights have become so fashionable that most people are opting for these over any other kind of lighting. So now if one thinks of a nightclub it isn't for the dark, ill-illuminated areas that have been presented in the by-gone years. With the versatility and the broad array of features offered by the LED club lights, each and every nightclub, bar and disco is expected to be a riot of colour with exceptional special effects.

So, why is that people appear to prefer LED club lights to regular standard ones? The reasons for this are the exceptional features that are available with the LED club lights:

Power efficient: Among the finest features that appear so appealing to nightclubs is the energy efficiency. As in contrast to the tungsten or the halogen lamps, the LED lights demand less energy and yet provide far better illumination as in contrast to the previously illumination sources. Thus, it is not unbelieveable that nightclub proprietors prefer LED lights to other sources of illumination.

Eco-friendly: Being eco-friendly is the most recent trend. Right from creating a structure to the type of illumination used, people are looking for environment friendly alternatives. Far more people are now worried about the environment which is why the LED club lights have become so fashionable presently. Not only do they need much less energy to work but these lights don't have any toxic chemical substances like halogens, mercury, and so forth, as a result obviously starting to be a a lot more eco-friendly option.

No warmth dispersal: Among the most typical difficulties encountered in most nightclubs is the warmth. The immense number of light sources especially the halogen and tungsten bulbs dissipate huge amounts of energy as a result making the place hot and uncomfortable. And to fight with this immense warmth it is essential to set up fans and AC that is an added expense. But now with the LED club lights this issue of too much warmth is easily managed because LED lights are "cool" sources of illumination and don't dissipate extra warmth.

Longevity: Finally, the finest and the most appealing characteristic besides being energy efficient is the longevity of the LED club lights. As in contrast to the other sources of illumination these lights provide 50 to 100 times far better service life and thus work for a longer time period.

Old is Gold: Traditional Unparalleled Servo Motion Control

 

The evolutionary concept of Servo Motion Control did not pass through any significant change over the last 50 years. The servo amplifier, being a part of a closed-loop control system is still used to control an assembly positioning system. The sensor less brushless motor controller used in a variety of electro-mechanical and electrical machines now-a-days is based on the traditional theory and algorithms of servo motion control.

 

A little insight into servo motion control: First we need to understand what a typical motor controller is and what it exactly does. It is a single or collection of device(s) governing in pre-determined manner to control the performance of any electrical motor. The controller itself includes a manual or automatic measure to start/stop, selecting as well as regulating the torque and the speed, selecting the direction of rotation. Some failsafe measures should also be there like protecting itself against overloads and other faults.

 

An electric motor controller can further be classified according to the type of motor to be driven. Servo amplifier is one of those types using error-sensing negative feedback in order to correct the performance and accuracy of a mechanism. It is a special kind of electronic amplifier used to power up electric servomechanisms following the algorithm of servo motion control. It monitors the feedback signal from the servomechanism and performs contiguous adjustments for deviation from any expected behavior.

 

The motor being used is not mandatory to be a servo motor. In case of a servo motor being used, the servo amplifier first receives a host command signal from the control unit, then amplifies it as usual, and finally transmits current to the motor for producing motion in it. In this typical case, a sensor is generally attached to the servo motor reporting its actual status back to the servo amplifier.

 

Sensorless brushless motor controller or commuted motors, on the other hand are powered by direct current and have electronic commutation measurement. The limitations of brushed motors like lower efficiency and susceptibility to mechanical wear and frequent need for servicing  have been overcome by the brushless type.

 

The servo motion control is just a technique that can be used both in good old servo amplifier and the modern-age relatively cheap and much efficient sensor less brushless motor controller systems.
