So when we look at the action of these four radiances that are used in commerciality, ultrasound, magnetic field, infrared laser and color LEDs, you will see that the action of these radiances primarily occur at the level of individual cells. So infrared laser and magnetic field support each other in providing energetic stimulus for the entire healing process. Color LEDs with the laser provide a regenerative message, a very specific type of information to the cell to start to initiate this process of regeneration. And finally, ultrasound together with magnetic field, they stimulate the metabolic processes so that this diseased cell with very slow and sluggish metabolism can now accelerate. So the structure can be built much faster. And the beauty of this process, when you apply all of these four radiances is that they act completely synergistically. In other words, you cannot compare action of individual radiance. If you take only infrared laser or if you take only magnetic field and all the ultrasound, you cannot compare them because when you combine them and all of them are acting at the same time in the same volume of tissue, these effects are strengthening and multiplying each other. And this is where the synergy comes up. And why it's important, it gives us a benefit of using a very low energetic output. So if you compare, let's say, a laser in a Delta device to something that you know as a, for example, low-level laser therapy device and our single individual device, they will have to use a very -- a high-power laser, whereas with Delta device, we're using extremely very low power, and this is because we have the synergy, this mutual support of individual radiances. And most importantly, all of these radiances do not override the natural functioning of the body.
