What Are The Advantages Of Using Electronic Tilt Sensors In Off-road Vehicles

Posted on by blogger

Off-road vehicles are designed to perform the most difficult tasks in often in the most extreme outdoor conditions. In industries like construction, forestry and agriculture, vehicles often have to navigate on uneven surfaces and slippery terrain whilst lifting and manoeuvring heavy and uneven loads. This can present difficult challenges for the drivers of these vehicles: for many vehicle operators, the chances of tipping or rolling the vehicle over are high, so obviously safety is a paramount concern. However, electronic sensing technology is now available which makes the vehicle drivers job easier and safer. As these electronic sensors can detect the vehicles operating condition and alignment, the safety of the operator is greatly increased.

Tilt Sensors Monitor the Safe Horizontal Alignment of Vehicles
Off-road vehicles often have to work in extreme conditions, where rugged terrain and heavy moving machine parts can quickly shift the balance of a vehicle. A shift in the dynamics of the vehicle or an uneven transfer of weight or dangerous alignment can cause hazardous conditions for the vehicle operator. Electronic sensors can help operators to monitor the horizontal alignment of vehicles. Tilt sensors can precisely detect even the slightest angle variation. Tilt sensors can give the driver accurate information about the exact road-grade angle, the boom angle, the platform angle and the crane-level angle. Armed with this important information, an operator can then take action to avoid a potentially disastrous situation.

Tilt sensors, however, need to sturdy and resilient. They have to be able to withstand the extreme shock, vibration, and all the harsh elements associated with outdoor use. Moreover they also have to be able to cope with direct exposure to chemicals, dirt, moisture, sunlight, and electrical interference. Therefore tilt sensors have been designed so that they are capable of resisting these elements and are able to perform in extreme environments. They are able to do so because of certain special design features like:

Compact housings rated for IP67 protection which encase and protect the electronics from chemicals and liquid ingress,
UV-resistant plastic and metal housings which prevent damage from exposure to sunlight,
Noise-immune technology which enables the sensors to ignore conducted and radiated electrical noise.
Outputs protected from short-circuits and overloads which eliminate damage during installation,
LHighly flexible cables, which are armoured to resist chemicals and perform at temperatures as low as 40 F.

Sensing technologies
There are two very different, yet highly effective sensing technologies that can be applied to verify the horizontal alignment of off-road vehicles: electrolytic tilt sensing and micro electromechanical sensing. (MEMS)

Electrolytic tilt sensing
Electrolytic tilt sensing technology can measure the tilting of a reference plane in two axes, by measuring the tilt angle with reference to the earths ground plane, using an accelerometer. At the centre of the sensors core are measuring cells surrounded by fluid or liquid. These measuring cells monitor ant change in the liquids conductivity to detect angle variations and deviations.

MEMS sensing technology
The second technology is micro electromechanical sensing (MEMS). When a vehicle lifts or tilts, the movement is transferred to the beams of the sensor that deflect to take the inertial force of the mass. The change in capacitance is proportional to the tilt of the sensor, which is ultimately then converted to a change of voltage and transferred as an analogue value to the driver of the vehicle. The use of MEMS sensors incorporating this technology are better suited to applications where a single-axis wide tilt angle (90) and lower precision (1) are needed.

Sell Electronics Online, For Free

Selling things online is a great way to make some extra money from home, but setting up an e-commerce store isn’t for the faint hearted. It requires a huge investment of time and money, and you can end up with nothing to show for it in the end. If you want to make some easy money online, there is one way that you can do it without having to pay a cent, or invest more than a minute of your time.

It might sound too good to be true, but it isn’t. The used electronics market is huge on the internet, and used electronics dealers always need fresh stock. This means that if you’re one of the millions of people with unwanted cell phones, iPhones, laptops, or other devices in your home, you can make a ton of extra cash by learning to sell electronics online. There are some serious advantages to doing this versus holding on to your old electronics:

– Since you already own the things you’ll be selling, you won’t need to lay out a lot of money for stock the way you would with an e-commerce shop.
– Since you’ll be selling your devices to a dealer, you won’t need to deal with customers directly.
– When you sell electronics online, you get money in just a few days.
– Since you’ll be selling things through another company’s website, you won’t need to pay for things like web space or site designers.
– Holding on to your electronics doesn’t do anything for you. You’re unlikely to ever use them again, and you won’t get any money for them if they’re just hanging around your home.

So, how do you sell electronics online without having to pay anything? You do it through a used electronics dealer’s website. These companies will pay you money for your unwanted devices, no matter what kind of condition they’re in. Even a broken device, like a smartphone with a cracked screen or an iPad that just won’t turn on, is worth some money to the right person. Instead of having to be the one to find that right person, you can put your old, broken, or unwanted electronics into the hands of someone who will.

On a used electronics dealer’s website, you can get a price quote in twenty nine seconds. All you need to do is know your device’s brand and model, and have a good idea of what kind of working order it’s in. Be honest! You’ll be quoted more for a device that’s in perfect working order, but your device will be inspected once it’s received by the company. When you sell electronics online, you’ll be paid for the condition your electronics are actually in, so it’s in your best interest to tell the truth on the company’s website.

If you like the offer, the next step is to continue with the transaction by requesting a free mailer from them. You’ll be sent a special box or padded envelope that is already stamped with the necessary postage. So, not only to you not have to pay for stock to sell electronics online, you don’t need to pay for shipping, either. When your mailer arrives (most likely in a few days, depending on postal service in your area), you simply use it to mail your electronics in to the used electronics dealer.

The last step to sell electronics online is to wait to be contacted by the company buying your devices. They will confirm the condition and model of your electronics, and discuss payment options with you. In most cases, you’ll be able to take your payment as an online transfer, through a service like PayPal. If you prefer, you may also be able to take it in the form of a check or money order. You’ll get your payment a few days after that, and your electronics will be resold.

E-commerce sites are a great idea, but not everyone has the money and energy to invest in them. Instead of having to sell electronics online yourself, why not rely on experts in the field of selling electronics? Turn your unwanted devices over to the right company, and you’ll get to walk away with some fast cash with little to no effort.

A Brief Introduction To Nextbase Protable Dvd Players

Posted on by blogger

Key Features

One of the most important, if not the most important, components of a portable DVD player is its display, or screen. The size, and other characteristics, of the screen determine the quality not only of what you actually see, but also the overall dimensions, and weight, of a portable DVD player. Most LCD (Liquid Crystal Display) screens, nowadays, are TFT (Thin Film Transistor), or active matrix, in design, and offer bright, colour rich, results, even in conditions of bright ambient light. The Nextbase N2 SDV47 model, for example, is a tablet style portable DVD player, with a 7 inch, TFT display, while the Nextbase DVM235 model features a pop up, 3.5 inch, TFT display.

Screens as small as 4 inches, and as large as 17 inches, measured diagonally, are available, with 7 inches being typical. Do remember, however, that while a larger screen can be easier on the eyes, if you intend to view for long periods, the player, itself, and its batteries will, by necessity, also be larger, and heavier.

It may be that you wish, at some point, to connect a portable DVD player to your existing home entertainment system. If this is the case, connectivity is important, and you should look for the highest quality output connections appropriate to your system. These may include S-video, and coaxial, or optical audio outputs. You may also be looking for support of true digital surround sound, in the form of Dolby Digital, or DTS; Dolby Digital is an industry standard for commercial DVD recordings.

About Nextbase

Nextbase is a Hong Kong based manufacturer of high end audio/video products, with over 15 years experience in the portable DVD player industry. The company strives to incorporate new electronics technology into its range of exciting and innovative products, employs a strict quality guarantee system, in accordance with international standards, and has formed strategic partnerships with other leading players within the industry.

Conclusion

If you are planning to use a portable DVD player in a moving vehicle or in any other environment where it is likely to be subject to vibration, or the occasional shock, it is good idea to invest in a model that has skip protection. Similarly, there may be other considerations, particular to your circumstances, which mean that some features are more important than others. A portable DVD player with a large screen, for example, is fine, but may not be very convenient if you have difficulty fitting it into your bag, or briefcase, and disappointing, if its battery life is only an hour, or so.

Tips for Storing Computers and Electronics in Self Storage

Posted on by blogger

While household items like furniture are very straightforward to put into self storage, what do you do about electronics and computers? These delicate items must be carefully packed and stored to prevent damage. While water is obviously hazardous, extreme heat and cold can also damage electronics.

Here are some tips to keep your electronics safe in storage.

Why Should You Avoid Storing Electronics?

Before we discuss the best ways to store electronics, it’s important to understand why you should avoid putting electronics into self storage at all, if possible. When the weather gets hot, the temperature inside storage units skyrockets, just like a car, unless the unit is climate controlled. This can easily destroy sensitive electronics, including computers and flat-screen televisions.

Choosing the Right Storage Unit

Most self storage facilities have several types of units to choose among. With electronics, you will always want an indoor climate controlled storage unit. The temperature in these units remains between 50 and 80 degrees with central heat and air, which prevents corrosion or cracks that damage electrical components.

Moisture control is just as important as temperature control when you choose a self storage company. Choose a company that uses a dehumidifier to keep out dampness if you live in a humid climate.

Tips for Safe Electronics Storage

Always begin by backing up all important information and storing it elsewhere. Take the tapes out of any VCRs or devices, and the CDs and DVDs out of drives and players. Equipment should be covered with cotton sheets or canvas — never plastic — to allow air to circulate. Plastic should never be used, as it traps in moisture. If you can, store your devices in their original boxes.

While your storage unit is empty, add pallets or boards to raise your electronics off the floor. Use cardboard or bubble wrap to protect screens, scanners or monitors and mark all glass parts as fragile to avoid placing any heavy or sharp objects against them.

If you have any questions about how to safely store your electronics, check with the self storage facility manager. You may also want to ask about storage insurance, particularly if you are going to store valuables. Above all else, remember that you should never store anything that you can’t replace. Think carefully about storing electronics, as they are at a greater risk of being damaged in storage from the elements and no one wants to pay to store something that is no longer functioning.

Electronic Control Module Tuning With The Unichip Q

Posted on by blogger

The up to date Sequential Electronic Fuel Injection Control System is made of sensors which observe the actual engine requirements, the Powertrain Control Module (PCM) which operates the particular system primarily based on return signals from these electrical feedback sensors, as well as actuators which are powered under the control of the actual ECM.

The ECU (Engine Computer) carries out activities such as fuel injection control, idle air control, and spark ignition control.

In addition, the Powertrain Control Module is loaded with many different diagnostic test settings which usually streamline trouble shooting any time a new trouble code appears.

The two most common calibraion tables that you need to manipulate or modify is undoubtedly the timing map and as well fuel map

Ignition timing control

The ignition power transistor placed located in the ignition main circuit turns ON and OFF in order to regulate the main current rate to the ignition coil. This controls the ignition timing so that it will generate the optimal ignition timing with regard to the engine performing conditions. The actual ignition timing is determined by the ECM (aka The Blackbox) as a result of rotational speed, air flow, engine coolant temperature (ECT), and atmospheric pressure.

Injector control

The injector open milliseconds (MS) as well as injection timing remain controlled so that the perfect air to fuel mixture is delivered to the engine to correspond to the continually-changing engine operating conditions. A correctly scaled injector is mounted in the intake port of each cylinder. Petrol is sent while under pressure (around 55 psi) coming from the gasoline tank to the actual fuel injectors through the fuel pump motor, with the actual pressure being regulated by the fuel pressure regulater at around 55 psi. The controlled fuel is then distributed evenly to each one of the injectors. Sequential fuel injection is usually performed one time for every cylinder per two rotations of the crankshaft. On a four cylindr engine the firing order will be 1-3-4-2. Each cylinder has a dedicated gasoline injector. This is known as multiport injection. The ECM (Engine Computer) provides a richer air/fuel mixture by carrying out “open-loop” control when the engine is cold or operating under high load conditions in order to maintain engine performance.In addition, when the engine is under normal operating temperature after warming-up, the ECM manages the air/fuel mixture using the heated Lambda sensor signal to handle “closed-loop” control. The closed-loop feedback accomplishes the theoretical Air-fuel mixture ratio where the catalytic converter can obtain the absolute maximum clean-up operation.

Using the Unichip Q-plus you will have total control over these variables to make alterations to the timing and fuel calibrations. The Unichip PnP has 24 RPM sites between 100 RPM and 24000 RPM and 13 load sites between closed throttle full throttle position. This equates to 312 available tuning points for each map. In turn the Unichip PnP is going to interpolate in between each speed and load site 16 times which gives a decent resolution densed map.

UniQ is Unichips most recently released software package for tuning engine ECU’s. This software program is a revolutionary change from old style DOS model which had been in operation for over a decade. Take the Unichip Tuning software for a test drive and see for youself.
