Sentences with phrase «of radio frequency energy»

Not exact matches

Phones aren't chemicals, so they're not on the official Prop 65 list, but the California Department of Health still warns that the radio frequency energy they emit might cause cancer.

The main concern people have about cell phones is that they emit radio - frequency (RF) energy, a type of radiation.

So it may seem scary that the California Department of Public Health has issued guidelines to help people «decrease their exposure to the radio frequency energy emitted from cell phones.»

If you provide energy in the form of radio waves, these tiny magnets can switch orientation and give off a resonance frequency that changes predictably based on the strength of the magnetic field.

When a radio - frequency electric pulse is applied to one end of such a tube (Anderson and Alexeff use fluorescent lamps), the energy from the pulse ionizes the gas inside to produce a plasma.

Designing radio technology into computing systems requires the use of mathematical equations and scientific methods to solve real - world problems that affect our customers such as radio frequency interference or battery life due to transmission of energy.

«If you could measure the frequency of this radio signal, you could measure the energy potentially much more accurately than you can with any other method,» Furse says.

The system, built by L - 3 Communications in Woburn, Mass., emits beams of radio - frequency energy that are tuned to reflect well off human skin.

Radar pulses (short bursts of radio - frequency energy) emitted from a ground - based transmitter are reflected by a meteor's trail.

As the US space agency announced on Wednesday, the Van Allen space probes have detected a new, artificial bubble surrounding Earth that was the result of the interplay between very low frequency (VLF) radio communications and high - energy radiation particles.

«A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high - energy radiation environment around the Earth,» explained Phil Erickson, assistant director at the MIT Haystack Observatory in Westford, Massachusetts.

«A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high - energy radiation environment around the Earth,» Phil Erickson, one of the scientists involved, said in a statement.

Filling out the entire electromagnetic spectrum, in order of low - energy and low - frequency to high - energy and high - frequency, we have: radio waves, micro waves, ROYGBIV, ultra violet, x rays, and gamma rays.

Voyager emits specific low level radio frequency energy that blocks cancer cells from dividing by blocking the dis - assembly of microtubule, leading to aberration, multi-nucleation and interruption of mitotic spindle activity during cell division, at metaphase

Vintage clocks are used to play with time, and radios connect sound and frequency to the unseen energy of «radio waves» while «space age» TV antennas both send and receive messages.

There are non zero probabilities that by 2030 we might have some or all of (i) thin film solar cells with 40 % efficiency installed for $ 1 / watt, (ii) «batteries» with at least five times the capacity of lead acid and one fifth of the weight, (iii) boring old solar thermal plants with no drama plugging away, (iv) there may be some one using solar cells in space sending power to earth as radio frequency energy.

But that could be changing in the near future, as some small low - energy IoT devices could be powered by the virtual «electrosmog» that surrounds us all the time - the radio frequency (RF) transmissions of the wireless and mobile networks that are broadcast around us.
