Cold Sore Remedies Cold sores are fever blisters caused by a virus. They are not the same as canker sores, even though the two are often mistaken for each other. Cold sores are caused by the herpes simplex virus (HSV), the same virus that also causes genital herpes.

Radiofrequency ablation Radiofrequency ablation. (Redirected from Radio frequency nerve lesioning) Radiofrequency ablation (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).

SR751 Smart RF (Radio Frequency) Repeater Module What is the SR751 Smart RF Repeater? The SR751 Repeater repeats X10 RF (Radio Frequency) signals. This is especially useful if you are trying to cover a larger area with any sort of X10 RF signal. Things like remotes, alarm systems and motions sensors really benefit from the RF Repeater. The unit also has an electrical pass-through at the bottom of the module so you don't even have to lose that outlet!

What is RF Testing? The RF part of the electromagnetic spectrum is generally defined as that part of the spectrum where electromagnetic waves have frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz).he frequency of an RF signal is usually expressed in terms of a unit called the hertz (Hz). One Hz equals one cycle per second. One megahertz (MHz) equals one million cycles per second. Different forms of electromagnetic energy are categorized by their wavelengths and frequencies.

RF Sensing of Humans in Urban Environments A potentially useful and technically feasible area of development is radio frequency (RF) sensors to detect and monitor human activities associated with bomb making and bomb delivery from a standoff distance. RF sensors provide unsurpassed range, 24-7 operation and good penetration through building walls. Human body and limb movements also result in unique microDoppler features that can be detected easily. There are a number of ongoing through-wall radar sensing programs funded by the US government.

Radio frequency However, mechanical RF systems do exist (see mechanical filter and RF MEMS). Although radio frequency is a rate of oscillation, the term radio frequency or its abbreviation RF are used as a synonym for radio – i.e., to describe the use of wireless communication, as opposed to communication via electric wires. Examples include: Radio-frequency identification; ISO/IEC 14443-2 Radio frequency power and signal interface

-   A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination.   For many years the modulated carrier wave was converted to a radio signal.

- With monopolar radio frequency treatments the RF energy is transmitted onto the skin using a single electrode, the opposing electrode is placed some distance away. Bipolar RF skin treatments are administered via an probe containing the two opposing electrodes.o recovery time is needed after a radio frequency treatment! You can just get up and go on with your daily routines. Results become apparent immediately but their maximum effect is visible some two months after the treatment cycle is over. Results last for years and treatments may be undergone again when necessary.
