Gadgets

Over the next year a whole host of brand new gadgets and exciting gizmos will arrive. Some will attempt to enhance our lives, whilst others will just want to keep us entertained, but all will interest and stimulate those who are interested in the latest technology. With that in mind, read on if you want to find out what is going to be big in the gadget world during 2010.

Power Mats
Most people will now be familiar with wireless internet connectivity and wireless peripheral tethering with Wi-Fi, 3G and Bluetooth coming integrated into many mobile phones and laptops. But wireless electricity transfer is a very different advance altogether. Power Mats are just one of the several new branded devices that are offering people the ability to recharge their battery-powered devices without the need for tons of different plugs and physical connection. At the moment devices like the iPhone, Nintendo DS and BlackBerry smartphones are supported, though you will need to equip them with a dedicated Power Mat receiver sleeve. You will also need the Power Mat itself, which can sit on any flat surface and charges devices fitted with compatible receivers whenever they are placed onto it. This uses inductive charging, which makes the system completely safe to touch and place non-electronic items on without fear of shock.

Pico Projectors
A decade ago it would have been incredible to display a mobile phone with a built-in digital camera, but now even the cheapest phones have them. In 2020 it is likely that most mobiles will also feature a built-in projector, capable of displaying video in a large format. Various companies are working on pico projector technology and some claim that the first mobile phones featuring integrated projection will appear in 2010. The portable entertainment and presentation possibilities this will create are impressive.

iPhone 4G
Expected to be released at some point in June 2010, the next generation of the iPhone will introduce even more power and versatility than its forebears. Rumours suggest that it will have an OLED screen, a 5 megapixel camera and even a touch sensitive case similar to Apple`s Magic Mouse technology for gesture inputs. Whatever happens, the whole of the mobile manufacturing industry will be looking to the iPhone 4G to see which trends it will create next.

Project Natal
Microsoft`s Xbox 360 is getting a brand new hybrid motion and video capture accessory this year, which has been undergoing development with the Project Natal moniker. It will allow for unprecedented immersion in rich gaming worlds and should rival the Wii in terms of how much physical energy you will need to expend when playing a game.

2010 should also be a good year for accessories, which piggyback on existing gadgets to make their mark. Expect the availability of the next generation in mobile networking technology, referred to as both 4G and LTE, to result in many mobile internet dongles with high speed connectivity to hit the market. Choosing between these and other accessories and gadgets can be difficult and to get the best deal price comparison is always advisable.

Introduction
Fundamentally, wireless computer speakers operate in the same way as all loudspeakers; an electronic audio signal is translated, by a process involving magnetism and electromagnetism, into the physical vibration of the loudspeaker cone, reproducing audible sound. The difference between wireless and wired speakers, of course, is that wireless speakers are not constrained by any form of physical connection to the source of the sound. Instead, a transmitter connected to your computer - often, nowadays, by USB (”Universal Serial Bus”) - provides a wireless link to the speakers, which can, therefore, be positioned to your liking around your listening space.

Wireless Computer Speaker Features, Benefits & Considerations
One of the great advantages of wireless computer speakers is that they can be truly “wireless” - unlike wireless home cinema speakers, which typically require mains power - operating on standard, alkaline AA, or AA, disposable batteries, or rechargeable batteries. This means that they can be positioned around your desktop, or throughout your home office, and beyond, without the need to be near a mains power outlet, and without trailing wires.

Wireless computer speakers are also available in a number of different configurations to suit specific applications. A so-called 2.1 channel wireless speaker system is capable of reproducing two main sound channels, plus an LFE (”Low Frequency Effects”) sub-channel, and therefore comprises two loudspeakers, plus a specialised loudspeaker, known as a subwoofer. Cables Unlimited Wireless Speakers, for example, are “two way” speakers, capable of operation on disposable or rechargeable batteries, and offering arrange of up to 150`. A 2.1 channel configuration is fine for everyday music, video clips, gaming, etc., but for a lifelike, immersive, listening experience, you may also like to consider a 5.1, 6.1, or 7.1 channel configuration. These configurations - provided, of course, that they are supported by the sound card in your computer - add extra satellite speakers, which can be positioned to the rear, and sides, of the listening position, so that sound emanates from a full 360°. Creative GigaWorks G550W Speakers, for example, offer 36 Watts RMS per channel, on each of 5 main sound channels, and a 130 Watts RMS subwoofer.

Wireless speakers are available in a number of slightly different forms, utilising RF (”Radio Frequency”), WiFi, or Bluetooth® technologies for “through the air” transmissions. These transmissions are typically in the 900MHz, or 2.4GHz, frequency bands of the radio spectrum, and may therefore be susceptible to other domestic devices, such as microwave ovens, cordless telephones, etc.. You may therefore need to give due consideration to any of these devices - and, indeed, any other 802.11 wireless devices - that you may already have in your home.

Digital cameras are designed to capture images via an electronic image sensor. It utilizes a form of removable storage called flash memory, one of the essential digital camera accessories. Flash memory is a non-volatile (no-power consumption) EEPROM (Electrically Erasable Programmable Read-Only Memory) type that can be re-used and re-programmed. It offers fast access time for reading information and images.

The first flash memory was invented by Dr. Fujio Masuoka in 1980 at Toshiba circa. The name flash was advised by Mr. Shoji Ariizumi (Dr. Masuoka’s colleague), reminding him of the camera flash.

A flash memory stores information in a number of memory cells, made from floating-gate transistors. It is made with a card case durable enough to withstand pressure, temperature and water. It can be inserted to a camera compartment. Images are taken and processed automatically. It has a range capacity of 128 megabytes to a number of gigabytes. More pictures can be stored in a high storage capacity memory.

Below are a few examples of flash memories:

CompactFlash
CompactFlash is a 50-pin digital camera memory card. It is used in many applications used to interface with PCs, PDAs and printers. Type I and Type II are the 2 physical sizes available. Some cameras accept only Type I. Type II is much thicker and has a higher capacity. One common Type TT cards is the MicroDrive memory card. It also has a built-in controller chip. This allows higher transfer rates on cameras with larger internal buffers.

CompactFlash was built something similar to Intel’s NOR-based flash memory. It became the oldest and most inexpensive formats in the market today. It is available in 512 MB (megabytes) to 100 GB (gigabytes) capacity. 1 GB and 16 GB are one of the popular choices in North America and Europe.

CF memory cards are the most desirable types because of its rugged design. It withstands more physical damage as compared to other portable storage devices. It lacks the write protection switch that other devices have in common.

Secure Digital (SD)
Secure Digital is one of the non-volatile memory card format widely used in digital cameras, computers and mobile phones. The slim and compact design is just about the size of a postage stamp. A decoder software of SD enables you to play music and video clips.
SD was developed by Matsushita, Toshiba and Scandisk. The card ranges from 4 MB to 4 GB. It has a physical size of 24 mm * 32 mm * 2.1 mm, providing both DRM to a SDMI standard.

SD cards are supported by the older MultiMediaCard (MMC). It has a transfer rate of 10-20 Mbytes. It supports at least three of the transfer modes. These include the One-bit SD mode (separate data channels, commands and transfer format), Four-bit SD mode (uses reassigned and extra pins) and the SPI mode (subset of the SD protocol use with microcontrollers).

Memory Stick
A memory stick is a kind of digital data storage launched by Sony last October 1998. It is designed for small digital products because of its compact design. The 8 MB memory stick is available in 4, 8, 16, 32, 64 and 128 MB storage sizes.

This type has a data transfer rate of maximum 20 MHz with a 10-pin connector type. An Erasure Prevention Switch can set lock to eliminate accidental erasing or recording of data. It also has original serial protocols for compatibility issues. It includes a family of Memory Stick PRO, Memory Stick Duo, Memory Stick Micro (M2) and the Memory Stick PRO-HG.

A digital camera is a device used to take photographs and videos. It can display and store thousands of images to capture great moments. Even the smallest sized ones are loaded with excellent features. Most manufacturers tend to make extraordinary designs for a more trendy and convenient look.

The first digital consumer-level cameras via serial cable had a number of models from different brands. There was the Apple QuickTake 100 camera produced in 1994. Kodak and Casio also released their own models in 1995. Sonys Cyber-Shot came out the following year. More designs are yet to be introduced in the market in the following years.

A typical level switch is a simple on/off indicator showing whether the liquid level in a vessel is above or below the switch’s location. Creative use of multiple switches allows a more precise picture of a tank’s contents.

Simulating Continuous Level Indicators

Many vessels are designed with only one or two level switches. Depending on the expected operation there might be a switch near the top to signal the tank is full and/or one at the bottom to let operators know the tank is nearly empty.

Instead of one or two level switches, vessels can be fitted with several switches each at a different level in the tank. As the tank is filled, switches are triggered in sequence as the level rises past each one. When the liquid level starts to fall, switches are deactivated from the top down. Signals from the switches can be routed to a control board to provide a stepped continuous level indicator that gives operators more information than a single switch could.

Mapping Trends

Rather than just knowing what the current level of liquid is, operators often need to know how that level is changing. Installing a series of level switches allows operators to track changes in liquid level as well as the level itself. They can see what direction the level is going and make any response necessary to maintain equilibrium.

These trends can be used in process control systems to make more precise adjustments to flow volumes or other operational parameters. The system can respond not only to the level in the tank but whether that level is increasing or falling. The more information the process control system has, the more efficiently it can respond to changing conditions in the system.

Complex Control Logic

In a simple control system, a safety valve might open once a level switch triggers indicating a tank is getting too full. When the level drops, the valve closes again. With more information, process control engineers can design control systems that can make more complicated decisions than “on/off”.

An advanced control system can examine the level and rate of change of liquid in a vessel and make decisions accordingly. To extend the example above, if the control system sees the tank is full but also sees the level is dropping, it is not necessary to open the emergency valve. On the other hand if the level is below the critical threshold but rising quickly, the valve could be opened early to deal with the overflow before it becomes a problem.

A level switch is a simple device but that doesn’t mean it isn’t capable of complex operations. Incorporating a network of switches into a process control system allows operations to run more efficiently and with finer control.

Gas grills have multiple varieties but they basically fall into 2 categories: charcoal grills and gas grills. Lately there are also electric indoor grills.

Although many people constantly compare the merits of gas grills and charcoal grills, the two remain traditional methods of grilling up to now. However, amongst the two, the most competitive and highly in-demand in the market are charcoal grills.

Charcoal grills come in a range of steel or custom designs. There are 55 gallon oil drums sawed lengthwise to their sides as their grill base and lid, to huge vehicle-sized grills made from brick which weighs almost a ton.

Barrel Grills
Assessing it in its primitive form, barrel grills look like 55 gallon steel barrels sliced in half on a lengthwise manner. Its hinges are attached in order for the top half to form the lid; thus, the bottom half acts as the charcoal chamber. For airflow control, the vents are cut into its top and bottom sections. The lid is attached to the chimney. Along the bottom portion of 1/2 of the grill, the cooking grids and charcoal grids are installed while its legs are attached to it.

Barrel grills, like kettle grills, are excellent for grilling and barbecuing. When it comes to barbecuing, one end of the barrel has piled-up lit charcoal while the food is placed in the other section of the barrel. Once you close the lid, the heat can be controlled through the vents. Since, barrel grills are an all-time favorite; you will find many basic and fancy designs available commercially.

Here are some of barrel grills sold in the market:

Kingsford 28.5-inch Barrel Grill wit Optional 5pc. Tool Set

Cart Grills
Charcoal-fueled cart grills look similar to typical gas grills. They are generally rectangular in design and they have a cooking grid, hinge grid as well as a charcoal grid. They are mounted onto a cart that has side tables and wheels.

Certain gas grills have their way of adjusting the heat. This is by moving the cooking surface upwards, having the charcoal pan face downwards, through venting or combing all three methods.

Cart grills, although quite expensive, usually feature an ash collection drawer. This ensures that ashes are easily removed wile you are cooking. Since cart grills have a rectangular design, they are also perfect for indirect cooking. With all the features of charcoal-fueled cart grills, they can make the art of charcoal grilling as convenient as that of gas grilling.

Each digital camera differs in features and capacities. It also comes in different sizes. Some are very compact just like the size of your cellular phone. The professional units are bulkier. There are some with high color quality while others have low color quality. There are also digital cameras that have higher memory capacity while others only can store a few picture.

Along with the many models and newer versions come the numerous digital camera accessories. One of the most common is the flash memory. It is a kind of storage data device inserted in the camera so it could take much more pictures. It comes in different capacities like 1GB or as high as 16GB. It can be inserted in card readers so you could transfer picture files from one device to another.

Memory cards are where you store your photos and videos while you have not yet transferred them to your computers. It is better that you buy the largest capacity possible because you will need it to store more than a hundred photos from your digital camera. You will need only one memory card if it is large enough.

Batteries and chargers are also very important. You need to have a spare battery so that you would not be caught in the middle of a special occasion without a spare if the current one runs out of charge.

The two way radio market can be a confusing place, especially if you are new to the market, and much of the jargon found when looking into an Icom, Vertex Standard or Motorola radio can lead to potential buyers purchasing a unit which is filled with features that they don’t really need or worse - missing features that they really do require.

The first thing people should look into when entering the two way radio market is whether they need to be on a licensed or unlicensed spectrum. In a nutshell, this means that some broadcast frequencies require a license to operate on, whereas others will not. The main advantage of licensed spectrum communications is that the licensed channels have fewer users on them than their unlicensed counterparts, meaning that they are less crowded and thus are less likely to suffer from cross-channel interference and other people intercepting your transmissions by accident and vice versa.

The main disadvantage of licensed spectrum communications is that they will often mean that your Kenwood, Icom or Motorola radio will cost more than a comparable unlicensed model, and obviously they will also need all other people in the communications group to be on licensed spectra as well, meaning that the outlay for radios could well turn out to be fairly large.

Whether or not you need to be on licensed spectra will depend entirely on the reasons you are purchasing your Vertex Standard, Kenwood or Motorola radio. If you are purchasing a handful of walkie-talkies to keep in touch with friends at a music festival where or on a college field trip, a licensed unit is an unnecessary expense; the cost of the radio plus the license is something that could well be cut down on by buying a cheaper, unlicensed model which will be better suited to an occasion such as this.

Ultimately, whether you need an unlicensed or licensed two way radio will depend entirely on your reasons for entering the market and the kind of requirements you have from your communications. Unlicensed spectrum radios are typically cheaper and will offer the advantages of a quick ‘pick up and go’ as they don’t require the process of acquiring a license for the frequency. However for more serious use, such as working security or organising a large scale event, it will be vital that transmissions get where they are supposed to be going with no concerns over interceptions or interference on the frequency and for this application, licensed units will be the way to go.

Whichever band you decide you need from your Icom, Kenwood or Motorola radio, making sure that you are aware of the differences between licensed and unlicensed communications devices can be the difference between spending a lot of money and time on an unnecessary feature or trying to save money and missing out on one that you or your business really needs.
