Billions of people use cell phones and more than 80% of the world's population has access to cell phone service from cellular antennas. Wi-Fi signals permeate businesses, public areas and homes everywhere. the number of wire-less device is expected to rise sharply in the coming years, and many are concerned about potential health effects from cell phones, cellular antennas and Wi-Fi devices. Some cell phone users who suffered rare illnesses have filed lawsuits against cell phone companies, but the cases usually are lost due to lack of scientific evidence linking the use of the phones to the illnesses. While debates rage in communities over placement of cellular antennas, the consideration of health effects on residents is muted because the federal government's Telecommunications Act of 1996 prohibits local governments from considering health effects when making decisions about cellular antenna placement.
The law does not apply to Wi-Fi antennas and some municipalities reject municipal Wi-Fi deployments due to residents' health concerns. It generally is agreed that no studies conclusively demonstrate negative health effects from cell phones, cellular antennas and Wi-Fi devices, but skeptics claim that the technology is too new to have endured long-term studies on humans. Long-term studies that are underway may not provide results for decades.
So i find that law that was passed was very foolish how could a government not have any say about things that are or may be a health risk to people?
Ok share your thoughts with me and if you like you can answer one of my questions.
Are you concerned about cell phone, cellular antennas or Wi-Fi radiation?
Do you or anyone you know minimize use of cell phones or other wireless devices due to health concerns?
Do you think that the governments should be required to consider health concerns when making decisions about wireless deployments?
Tell me, would you live next to a cellular antenna?
Why or why not?

Tongue May Become Joystick to Control Devices
Ok so here's something interesting i read in my Computer
& Information System text book. They are considering using the tongue as a Joystick to control devices. The article stated that many people are paralyzed from their neck down due to spinal cord damage, however, these people still have control of their tongue due to the fact that the tongue is controlled by a cranial nerve and not the spinal cord.
So for these type of people the Georgia Institute of Technology's Tongue Drive system may be the input device that helps them control their lives. Ok so they are stating that in the Georgia Tech prototype the tongue is used as a Joystick. There is a magnet which is less than one-eighth of an inch wide which is surgically implanted under the tip of the tongue, and when a person moves his or her tongue, sensors on each cheek record the magnet's movements in one of six directions.
The directions are: left, right, forward, backward, single-click and double-click. The data is sent to a receiver on top of the person's head, which, in turn, transmits a signal wirelessly to a computer that controls an electronic device. Here is an example that was given, if the tongue moves forward and to the left, lights in the room could turn on or a wheelchair could roll forward. The article also stated that in a future development of the Tongue Drive System, it is been consider of also using the person's teeth as a keyboard. An individual tooth could be designated as a specific letter, so teeth could function, in effect as a keyboard.
So this article i found was pretty amazing the things that we can do with technology is so far advance. It is also amazing to see that someone is thinking about making the disables lives much better in this way they won't feel as helpless as they use to and some of them will be able to live on there own and do things for themselves.
So tell me guys what you think about this article share your advice and concerns. I would love to hear what you come up with also give this article a rating did you think that this device is awesome, dangerous or crazy.
Come let me know what you think!

Embedded Computers May Improve Quality of Life
The weather forecast may be close as your fingertips if plans to integrate embedded computers in everyday objects become a reality. Researchers are envisioning an umbrella with an embedded cell phone in the handle that will dial and then download the local forecast. The handle will glow green for good weather and flash red for imminent storms. Dancers can pin a small flower with an embedded motion-detecting computer to their clothes. When they move the embedded computer senses action and then synchronizes the tempo of music to this movement. Other embedded computers woven into can monitor heart and breathing rates. Wearing hidden embedded computers can help the elderly and people recovering from accidents and surgeries monitor their walking stride and pace. When their steps are uneven, the embedded computer can sound a warning and perhaps prevent a fall. Other embedded computers can give subtle feedback on the quality of physical activity.
Ok so this article has Advantages and Disadvantages, and everything has that but would you really want to have a computer with all the time?
This sounds crazy to me but that's just my opinion so tell me guys what do you think about this?
Share yours thoughts about this let me know what you think because i would love to hear your thoughts.

What is Computer & Information System?
Information system (IS) is the study of complementary networks of hardware and software that people and organizations use to collect, filter, process, create, and distribute data. The study bridges business and computer science using the theoretical foundations of information and computation to study various business models and related algorithmic processes within a computer science discipline.Computer Information System(s) (CIS) is a field studying computers and algorithmic processes, including their principles, their software and hardware designs, their applications, and their impact on society while IS emphasizes functionality over design.
Any specific Information System aims to support operations, management and decision making.In a broad sense, the term is used to refer not only to the information and communication technology (ICT) that an organization uses, but also to the way in which people interact with this technology in support of business processes.
Some authors make a clear distinction between information systems, computer systems, and business processes. Information systems typically include an ICT component but are not purely concerned with ICT, focusing instead on the end use of information technology. Information systems are also different from business processes. Information systems help to control the performance of business processes.
Alter argues for an information system as a special type of work system. A work system is a system in which humans and/or machines perform work using resources to produce specific products and/or services for customers. An information system is a work system whose activities are devoted to processing (capturing, transmitting, storing, retrieving, manipulating and displaying) information.
As such, information systems inter-relate with data systems on the one hand and activity systems on the other. An information system is a form of communication system in which data represent and are processed as a form of social memory. An information system can also be considered a semi-formal languagewhich supports human decision making and action.
Information systems are the primary focus of study for organizational informatics.
