Officials said the fear is that if every student was equipped with one of the emergency devices, there could be police and firefighters called to the school every day for no reason.
But Crystal Ricardo said her son's safety is worth fighting the district over.
"I bought this device so my son can be protected when he's not around me," she said.

LifeLog was a project of the Information Processing Technology Office of the Defense Advanced Research Projects Agency According to its bid solicitation pamphlet, it was to be "an ontology-based (sub)system that captures, stores, and makes accessible the flow of one person's experience in and interactions with the world in order to support a broad spectrum of associates/assistants and other system capabilities." The objective of the 'LifeLog' concept was "to be able to trace the 'threads' of an individual's life in terms of events, states, and relationships."

Thank you, Tetra!
Your words ring true as well. We are moving towards events right now that are going to be down right frightening, but if we learn to step back from fear before those events happen, we will have better control over ourselves with whatever the situation may be and keep level heads. Keeping cool in a bad situation saves more lives than succumbing to fear.
Thanks again for contributing wise information.
Electromagnetic radiation or electromagnetic fields, commonly known as EMFs, are all around us. EMFs are found everywhere that electricity is in use and around any object that has an electric charge. EMFs are invisible lines of force that surround all electrical devices and wiring. Any time an electric current runs through a wire or an appliance, it produces an EMF. Electromagnetic radiation from Extremely Low Frequency (ELF), Radio Frequency (RF), and Microwave Frequency emissions are harmful to all living things.
Before humans harnessed electricity, the only electromagnetic radiation we were exposed to came from the forces of nature, from gamma rays and sunlight to the magnetic field of the earth. Many of today’s technological applications use or produce electromagnetic energy.
For the last century, technology has been a blessing to all human beings. The newly developed innovations and inventions have reduced the time needed to accomplish our goals and drastically improved the overall quality of our lives. Familiar examples include electrical lighting and appliances, computers, computer monitors, and microwave ovens, radios, TVs, and cellular phones, broadcast stations, surveillance systems and communications satellites.
Many writers and even researchers have already embraced the enormous and wonderful effects of this technology on our lives. The first warning of the dangers of this technology occurred in 1972 when the Soviet Union reported strange health effects in switchyard workers who were regularly exposed to high levels of EMF. Since then, scientists have been questioning whether this technology is causing more harm than benefits, not only for humans, but also for every living thing including animals and plants. This is because of the association of electromagnetic fields with increased behavioral changes and health problems such as epilepsy, leukemia, cancer, brain tumors, and other serious disorders. Many scientists and physicians suggest a link between these disorders and long-term exposure to EMF.
There has long been a scientific debate amongst researchers and it seems that for every study, which supports this link, there is an equally contrary finding in another study. Yet, in a 1989 report to the Congressional Office if Technology Assessment, Dr. Janet Healer stated: “Studies over the last fifteen years have demonstrated unequivocally that under certain circumstances, the membranes of cells can be sensitive to even fairly weak externally imposed low frequency electromagnetic fields. Extremely small signals can trigger major biochemical responses critical to the functioning of the cell.” Enough evidence has been reported to date to at least justify further investigation into the possible health effects of the electromagnetic radiation.
Yet, the government, electric utility and communications industry, and manufacturers maintain that there’s not enough evidence to make them take action. This is the same thing that was about asbestos for years until it was proven to be harmful. Tobacco companies still insist that smoking does not cause cancer. (Is this still true?) Lead manufacturers denied that lead added to paint was a hazard to children and it took fifty years before it was removed from paint and longer before it was removed from gasoline. The utility and communications industry are wealthy and powerful organizations and there is a danger that scientists who accept funds from them will have their public position biased by their financial support.
In 1990, the Environmental Protection Agency (EPA), the federal agency charged with warning the public about health problems in the environment, conducted a comprehensive review of available EMF studies and published a report recommendation that power line ELF’s be declared a probable carcinogen, and radio waves and microwaves be declared possible carcinogens. The White house and the Air Force declared that the report should not be published on grounds of national security and that it would alarm the public. The report was put on hold until the administration of the EPA changed the conclusions tbrain101.info...Electro Magnetic Field (EMF)

The Fermi Paradox
It may be that alien civilizations are detectable through their radio emissions for only a short time, reducing the likelihood of spotting them. There are two possibilities in this regard: civilizations outgrow radio through technological advance or, conversely, resource depletion cuts short the time in which a species broadcasts.
The first idea, that civilizations advance beyond radio, is based in part on the "fiber optic objection": the use of high power radio with low-to-medium gain (i.e., non-directional) antennas for long-distance transmission is wasteful of spectrum, yet this "waste" is precisely what makes these systems conspicuous at interstellar distances. Humans are moving to directional or guided transmission channels such as electrical cables, optical fibers, narrow-beam microwave and lasers, and conventional radio with non-directional antennas is increasingly reserved for low-power, short-range applications such as cell phones and Wi-Fi networks. These signals are far less detectable from space. Analog television, developed in the mid-20th century, contains strong carriers to aid reception and demodulation. Carriers are spectral lines that are very easily detected yet do not convey any information beyond their highly artificial nature. Nearly every SETI project is looking for carriers for just this reason, and UHF TV carriers are the most conspicuous and artificial signals from Earth that could be detected at interstellar distances. But advances in technology are replacing analog TV with digital television which uses spectrum more efficiently by eliminating or reducing components such as carriers that make them so conspicuous. Using our own experience as an example, we could set the date of radio-visibility for Earth as December 12, 1901, when Guglielmo Marconi sent radio signals from Cornwall, England, to Newfoundland, Canada. Visibility is now ending, or at least becoming orders of magnitude more difficult, as analog TV is being phased out. And so, if our experience is typical, a civilization remains radio-visible for approximately a hundred years. So a civilization may have been very visible from 1325 to 1483, but we were just not listening at that time. This is essentially the solution, "Everyone is listening, no one is sending."
More hypothetically, advanced alien civilizations evolve beyond broadcasting at all in the electromagnetic spectrum and communicate by principles of physics we don't yet understand. Some scientists have hypothesized that advanced civilizations may send neutrino signals. If such signals exist they could be detectable by neutrino detectors that are now under construction. If stable wormholes could be created and used for communications then interstellar broadcasts would become largely redundant. Thus it may be that other civilizations would only be detectable for a relatively short period of time between the discovery of radio and the switch to more efficient technologies.
One counter to this argument is that although broadcast communication may become difficult to detect, other uses for radio such as radar and power transmission cannot be replaced by low power technologies or fiber optics. These will potentially remain visible even after broadcast emission are replaced by less observable technology.
A different argument is that resource depletion will soon result in a decline in technological capability. Human civilization has been capable of interstellar radio communication for only a few decades and is already rapidly depleting fossil fuels and confronting possible problems such as peak oil. It may only be a few more decades before energy becomes too expensive, and the necessary electronics and computers too difficult to manufacture, for us to continue the search. If the same conditions regarding energy supplies hold true for other civilizations, then radio technology may be a short-lived phenomenon. Unless two civilizations happen to be near each other and develop the ability to communicate at the same time it would be virtually impossible for any one civilization to "talk" to another.
Critics of the resource depletion argument point out that alternate energy sources exist, such as solar power, which are renewable and have enormous potential relative to technical barriers. For depletion of fossil fuels to end the "technological phase" of a civilization, some form of technological regression would have to invariably occur, preventing the exploitation of renewable energy sources.

Fascinating information and thanks for adding it.
From what I've observed, EMF do upset our bodies. I've also noticed that trees close to power lines and towers appear to be dying.
One thing that bothers me is that it's practically impossible to get away from manmade sounds unless you go deep, deep into the woods. The fact that we're composed mostly of water, I believe that these frequencies upset the molecules in our bodies causing several different problems. All one has to do is watch the water experiments the Japanese scientist conducted and observed how chaotic noises caused the water molecules to change into weird shapes, while classical music and natural sounds caused the molecules to make natural shapes like snow flakes. I believe a lot of this goes back to sacred geometry and if the molecules within our bodies are kept in unnatural formations, we have health problems and psychological issues.
Alas, we must all realize by now that everything is connected and we're all becoming just as unbalanced as the Earth is. It's a shame what humans have done. I honestly believe that we're too smart for our own good.
