Catching The Geocache

Geocaching is the new craze fuelling the choice of places to visit of many tourists now. Geocaching employs Global positioning system (GPS) technology; small items of low value are hidden by tourists and then it is the turn of another group or tourist to find it. http://Geocaching.com is the website that geocachers use to communicate, when one makes a cache s/he records it there for others to find. Whoever finds it leaves something in turn. Items are simple and housed in a waterproof usually plastic container. It could be anything a CD, some trinkets, computer games key chains or books.

Getting into geocaching is not difficult; one gets registered on http://geocaching.com, buys a GPS system, buys a ticket or willing to drive and gets started. The GPS system which uses satellite signals to place the user at location anyway in the world to a few meters accuracy on a screen as well as how to arrive at other locations using their latitude and altitude measurements. By getting information about hidden caches from http://geocaching.com the player can then enter the coordinates for the hidden treasures around the area he is at and determines how to locate; once located he leaves something behind something and makes a record on the website.

A GPS system can be bought form any store that deals in open air equipment. GPS systems need not be expensive, but the more sophisticated ones are. Geo-caching needs tact and care need to be taken by cachers. Some cachers have been stopped by police for acting suspiciously in an attempt to hide their cache. They also need to take care not to be noticed by the public as caches have been "muggled', meaning vandalised or stolen by those who do not understand the game. When a geo-cache hunter finds a vandalised or stolen cache they make a record on the cachers' website and the original owner is alerted by email that then can replace, repair or delete the cache.

Other interesting ways to p-lay this game do not include a physical cache to be found but the players have to use the coordinates offered of the location and email back details of the place. A virtual cache requires a player to email back a name or date on a plaque or a picture of self at location, earth-cache needs details of the fossils or geology at the place and a webcam cache needs the player to take a picture of self using a public webcam at location.

Some geo-cachers travel overseas for cache hunting but some keep it local. It is an interesting activity that can be built into any holiday or adventure. It just makes it more interesting and is motivating.

Types Of Mobile Display Technologies

Author: Lijo George

A handset might seem to be just a device that lets you zaiK on a cellular network, but actually, there is a lot you need to know about handsets before you go out and buy one. What do you need? What kind of form factors are available? What about the battery? Then, there's the camera to be considered. Also, if a mobile phone is to be really mobile, you need to consider connectivity options. Then there are accessories to jazz up your phone -We round off this chapter with descriptions of a few especially desirable phones.

Display Types

Not only do mobile phone displays show caller information, menu options, contacts, etc., mobile phone displays these days need to be capable of displaying thousands of colours so that high-end features such as images and video playback offer the desired user experience. The followingis a brief on the various types of display technologies in use for mobile phones.

LCDS

LCD displays utilise two sheets of polarising material with a liquid crystal solution between them. Crystals in this suspension are naturally aligned parallel with one another, allowing light to pass through the panel. When electric current is applied, the crystals change orientation and block light instead of allowing it to pass through, turning the crystal region dark.There are two main types of Liquid Crystal Displays: STN and TFT.

STN

Super Twisted Nematic LCDs use the passive matrix screen technology, which has no active or controlling element inside the display cell. Pixels are controlled by energising the appropriate row and column drive lines of the matrix from outside the display, resulting in a slow frame rate. STN screens have limited colour range and viewing angles (~15 degrees max).

TFT

With Thin Film Transistor (TFT) LCDs, each pixel is controlled by one to four transistors. Typically one transistor is used for each of the RGB colour channels. Because of this direct control technique, TFT screens are also called Active-Matrix LCDs.TFT technology provides more accurate colour control, allowing it to display more colours and also offer a wider viewing angle range than other types of LCDs.

OLED

OLED stands for Organic Light Emitting Diode. OLED is a flat-panel display technology that is now being used in a variety of devices. Apart from mobile phones, you can also find OLED screens on portable audio players, car audio systems, PDAs and digital cameras. The basic property of OLEDs was discovered in 1985, over a decade before the first displays were seen. Ching Tang, a Kodak researcher, noticed that an organic material glows green if you pass an electrical current through it.An OLED is made by placing a series of organic thin films between two conductors. They operate on the attraction between positively and negatively charged particles. When voltage is applied, one layer becomes negatively charged relative to another transparent layer. As energy passes from the negatively charged layer to the other layer, it stimulates organic material between the two, which emits light visible through a layer of glass. There must be blue, red, and green light-producing organic material to produce the different colours. Because screens using OLED technology produce light themselves, they do not require a backlight as compared to LCD screens. This means that OLED displays require less power and also can be made very thin. Without any other source of illumination, OLED screens can display bright images that are viewable from almost any angle.Like LCDs, OLEDs also come in passive-matrix and active-matrix flavours.Passive-matrix OLEDs are made up of a matrix of electrically-conducting rows and columns making pixels. Between the rows and the columns are the organic layers. On the other side is the substrate, the material which gives the electricity. The more cur-rent applied, the brighter the display.In Active-matrix OLEDs, there is a TFT back plate instead of rows and columns. This controls the brightness of each pixel. There are two TFT arrays per pixel: one to start and stop the charging of the capacitor, and one to provide a constant electrical current to the pixel. Active-matrix OLEDs consume much lower power than passive-matrix ones.OLEDs have the following advantages over LCD or plasma displays: New-age displays: OLEDs can bring in new types of displays, like ultra-thin, flexible or transparent displays.

Power efficiency:

Since OLED screens do not require a back-i hey require much less power compared to other types of displays. This makes OLED a far better choice for portable devices.

GPS Handheld Devices - Breakthrough Technologies Give You a Path From a Higher Power Right In The Palm Of Your Hand

By: Korbin Newlyn

A GPS or Global Positioning System was in the beginning produced and controlled by the U.S. Department of Defense. Prior to it being utilized for commercial-grade reasons, the satellite system was utilized by the military for day-and-night navigation for earth, sea and air operations. As the GPS became extensively utilized for commercial purposes, its operations extended to allow for surveillance and movement of individuals, map making, forestry, mineral exploration, tracking down of endangered wildlife in their natural habitation and much more.

In the beginning, the Global Positioning System functioned on prominent computer systems but finally; it has developed into something more pocket-sized - the handheld GPS. The beneficial news about the handheld GPS is that it operates just like the GPS in more elaborate devices and it give the the user the ability to produce information anywhere and anytime he or she may choose. Handheld GPS have now earned such a following that there are numerous individuals all over the world that invariably depend upon the handheld GPS to assist them in navigating across the earth and find places which are even outside the navigation and location discovery ability in just the recent past.

Popular Handheld GPS Models

There are numerous handheld GPS models that are accessible in the market today. One of the more popular models of handheld GPS is the Garmin GPSMAP 60CSx, which is believed as the quickest when it comes in locking in to satellites. This handheld GPS is outfitted with a 2.6 inch color screen, a barometric measuring device, an electronic compass and an extra Geocaching menu. Nonetheless, despite the fact that this handheld device is filled with many functions, it merely weighs around seven ounces and could last for roughly 18 hours utilizing two AA batteries. The Garmin GPS is rubberized and is water resistant. If you aim to wade or swim on your journey, you could rely on this handheld GPS to come through.

The other well known handheld GPS is the Magellan eXplorist XL. This handheld GPS is features a 3.5 inch color screen which can still be viewable when subjected to sunlight. The big screen of the Magellan would give you a benefit when watching the maps and acquiring the data you need. Even so, the downside of the Magellan GPS is that unlike the Garmin GPS, it does not feature an altimeter or electronic compass. This handheld GPS also weighs approximately 12 ounces, which is quite heavy in comparison to the Garmin. The battery life of the Magellan is around 15 hours with the usage of four AA batteries.

GPS or Global Positioning Satellite technology was once the exclusive province of the United States Government. That has drastically changed in recent years. Read on to learn more.
