Do Laser At-Home Systems Really Work, and more

As I’m writing this post, I am appreciating the hot weather we are getting this month here in Oregon. It is not every day that we reach ninety or so until we get to June. To-morrow I am headed for my next laser appointment, and to stay on the safe side, I am staying away from the sun until I can get approval from the operator who will be administering the treatment.
So, the first question is, do laser at-home systems really work as well as the professional ones? Like electrolysis, people are trying to invent portable versions of the real thing, claiming that it’s light-weight flexibility will allow you to treat all areas without having your hands and arms getting tired. They also say that these devices can be used anywhere, any time. Already there are systems that use Alexandrite and diode lasers, but some may still use Ruby (no longer used) or intense pulse light configurations, thereby making it harder to use on people with different skin-hair combinations. Some are using broadband laser technology, which is the best that one can get because they can be made to use in any kind of circumstance. Currently, the most popular items being marketted today are the No!No! System, the Tria Beauty system, the Remington and Silk’n systems. For the purposes of this post, however, I will discuss the Tria and NoNo. A good blog article talks about the other systems in more detail: http://­www.beyondtalk.net/­home-hair-removal/­#comment-41942
No!No claims that it can treat all skin and hair types, but many people, as you will see in this video, said that it was like using a lighter on their skin and buffing the result with a large sandpaper. http://youtu.be/NaSiTMLzUSE
I should point out that treated hair roots should be left to grow and fall out on its own. Manipulating the hair can be painful and will also result in other problems with the hair follicles.
To find out what was real and what wasn’t, I decided to do some investigating to see how the mechanism of action worked for these types of items, and compare them to professional machine configurations. You might be thinking, after having read my previous post, that it would be nearly impossible to install a five-hundred-pound machine in your house with an examining table when you could just rest in your own bed and use a smaller version of the same system. I had the opportunity to test out the Tria Laser Precision, and I examined the technical specifications on the back of the manual to look at the numberings as well.
The Tria Beauty Laser Hair Removal Precision that I tested was equipped with three treatment levels, which determined the pulse intensity and duration that it would administer. On low, the device emitted a pulse that lasted about a hundred twenty-five milliseconds. On mediumm, the pulse was about two hundred fifty milliseconds long, and on high, five hundred. However, this device could not burn any hairs on or underneath the skin because it was not using the recommended configuration of three pulses, with an adjustable duration and delay counter. For this reason, the Tria did not cause burnt hair odour.
I tried to use this device with a numbing gel called Greencaine, but the result was that the contact sensor, located underneath the treatment window was blocked, so that it caused the device to send out flashes even if it wasn’t placed on the skin.
This unit only had one button, which was used to activate it for the first time, power it up, shut it off, and change the treatment levels. The only way I could tell which treatment level it was set to was by placing it on my skin and feeling the pulse, which would not be the best way unles I wanted to risk getting burned. It would be useful if Tria made it more accessible by making it possible to hear the tones. For example, a low tone would indicate that you had it on low, and a high tone would mean that you had it on high.
I was surprised that the unit came with a USB cable, which made me wonder if it was possible to hack into it and change its parameters, but when I plugged it into my laptop, my computer didn’t make any sound to let me know that a new device was plugged in. Instead, it started charging the unit.
The Tria Beauty Laser Hair Removal Precision was shaped like a cylinder, with a rounded treatment window that was curved, making it easier for one to put on their skin. It also came with a cooling fan, which was turned on immediately when I unlocked the unit with the skin sensor, also located underneath the treatment window.
When I looked over the No!No quickstart guide, it stated that topical preparations and any other skin products should not be applied prior to treatment. The thermal discharge can spark many flammable objects like nitrous oxide and other analgesic items. It also indicated that having a stubbly area to work with would be preferred than an area full of hair.
I asked myself this question. Is it possible for an experienced laser operator to use a professional laser system and treat themselves with it? Yes, they can, according to my laser operator.
So, what kind of configuration do these lasers use? Take a look at the web site to learn about the different kinds of configurations that are out there. I don’t know if it lists any particular manufacturers that make state-of-the-art systems, but you can at least begin from there. http://www.realself.com/question/whats-best-laser-hair-removal
From what I can see, the No!No uses special thermicon tips, which are capable of administering thermal energy within the infra-red spectrum–I may be wrong on this, but here is another link that can explain more. It’s not a professional resource, so I cannot guarantee that it will suffice. http://www.slideshare.net/KennGee/the-thermicon-effect-a-nono-hair-removal-secret-find-out-how-it-works
It’s primary focus is compressing the heat into as much as possible before delivering the pulse to the hair. I am convinced that the No!No is no more painful than lighting hair on fire, especially since their web site claimed that the procedure would be painless, but nothing is painless unless a person was immune to pain itself. Another disadvantage of the No!No is that it is so small that I cannot imagine that it would last long if one were to use it for quite a while. The thermicon tips certainly don’t last long at all. If you wanted to replace your tips, you would end up having to buy an entirely new No!No system. I do not recommend this product to anyone, unless they wanted to test it and make modifications to it. Like always, cheaper things tend to work better than more expensive things, since the primary focus is on making money, not on the actual treatment. No!No is able to make your hair burn and smoke and give you that familiar burnt hair smell. Hair is made up of proteins, just like meat, and this is one of the reasons why this kind of material releases aroma particles into the air that we breathe when it is set on fire.
Why do we have different skin colours and types than other people? If you look back at the time you studied anatomy and physiology of the skin, you might remember that sunlight is mainly the reason people adapt, and depending on the regions of the world, people will have more resistance to ultraviolet radiation than others. Obviously, people with darker skins have better resistance than those who have lighter skins. Those with higher melanocytes produce more melanim, which gives the skin a tan. Those with fair skins do not produce as much melanim, and therefore they would burn more easily. Human skin is never black and white, according to Neil Harbisson’s Human Colour Wheel. It is always between red and yellow, or light and dark shades and tints of orange. Bone structures and shapes are also dependent on racial backgrounds, all of which get genetically predisposed into future gametes. So, light amplification by stimulating and emitting radiation uses compressed photons to target only the dark areas, but at the same time, leaving the light ones intact. With newer equipment, broadband lasers and IPL’s can go deeper into the skin and target dark and light hairs, and a somewhat dark or olive-coloured skin combination. For a person to understand this concept, one must know a bit of physics involving how atoms and molecules work, and a bit of chemistry in terms of nuclear fusions and eventually come up with a raport between the client and the laser technician.
As stated in Mom, I need to Be a Girl, electrolysis and laser hair removal are more of an art practice than science, but I would say it is both, hence the term STEAM (science, technology, engineering, arts and mathematics).
Next up, do state-of-the-art machines and at-home systems have the same amount of power? No. State-of-the-art machines are capable of doing serious damage if the power was turned to the max, and its intensity can be so strong that people would be able to see the flash for more than several miles away. People are already using lasers as weapons against enemy planes to blind the pilots in hopes of bringing them down. The at-home systems only use enough power to treat areas and not cause accidental or intentional harm to oneself or others. So the question is, why would one need so much power to treat hair with a monstrous device? Many systems are already becoming more portable, especially those that weigh more than six hundred kilos on wheels. Some professional technicians can bring their equipment home and treat the client instead. http://www.innerbody.com/careers-in-health/how-to-become-a-laser-hair-removal-technician.html
Like electrology, a person has to undergo training to become a certified electrologist and or laser operator. If you are a self-motivated individual who is capable of administering your own treatment, go for it. I heard a lot about people doing self-surgeries and self-administrations in the medical industries and many have been successful despite the fact that professionals frowned upon them. No one should tell a person what they can and can’t do, since they are not that person to begin with. Only they can tell what their abilities and disabilities are. Some may require another person to do it for them simply because it just takes too much work. Doctors cannot legally diagnose themselves and their families. They usually need a fellow doctor to diagnose illness for them. One reason people don’t do a good job is because people spend time looking rather than using their other senses. As blind people, we learn to use those other senses. One of the things I learnt was that feeling outrules seeing.
I digressed big time in that last section, so I’ll get back on topic. People say that using both electrolysis and laser systems have side effects. There are many reasons why there are possible side effects, but I am convinced that many of these are preventable. Some are because the person is not responding well to the treatment. Some are caused by mutations of both skin and hair problems that make up the cells of skin and hair, which can lead to serious problems if not treated. The side effects are endless, and there are so many risks factors that can lead to each one that it will take forever for me to write down each one and explain its’ possible origin here. Suffice it to say that people should normally be fine after a treatment, as long as they are in good health and if the operator does the job well. Long-time operators will have a lot more experience than newer ones. Take a look at this article From The New York Times:
Laser Hair Removal’s Risks
The treatments can cause severe burns and disfiguring injuries, and a rising percentage of lawsuits involve operators who are not physicians.
http://well.blogs.nytimes.com/2014/01/06/laser-hair-removals-risks/
A quick question that popped into my mind was, why does it take eight weeks before you can get another treatment done, when you only have to wait a week or two at a time when using an at-home device? I suspect that this difference has to do with the fact that the professional machines have a lot more power than the little ones, as stated above.
Can laser surgery be used to remove ingrown eyelashes or such in other parts of the body? Normally, I would not recommend that laser surgery be used on the eyes because you would have to be put under, and it would also be extremely painful. Electrolysis was invented when the doctor found out that it had a great effect for visible ingrown eyelashes. For invisible ingrown eyelashes, however, surgeons would have to use a small beam that would hopefully destroy the damaged area using CO2, Argon, Xenon, or such laser gasses. The latter can be used to treat other skin anomalies, such as spider veins, anti-ageing, etc.
So, how do we know what is best for us? I believe in the KISS principle, so I intend on making this post as simple as possible for the average reader to understand. There are a few things that I will explain which hopefully makes sense when you picture it in your mind. Laser works in terms of wavelength and heat intensity. What does it mean when someone says, this is set to seven hundred fifty-five NM with three pulses that covers a large area. I should point out that the larger the light guide, the more effective and the lower the energy you will need to perform a successful treatment. This is because if you used a smaller light guide, there is a chance that scattered light would escape the target area, and you would have to repeat on the area more frequently with a higher setting. If you used one big pulse of energy, this could damage the skin than if smaller, more rapid pulses were administered, which would build up heat underneath the skin for the hair to burn. Lasering is not painful, but it is uncomfortable because of the very close heat. If the heat became too intense or if the hairs were very thick, then yes, it could be painful. This is because dark hairs will be absorbing the heat more than anything else. Light guides have a filter that only permit the red light to be administered through the glass, but the resulting flash becomes white in our eyes. If you ever used a magnifying glass to burn leaves or to kill bugs, the glass provides a similar principle. The sun’s energy gets compressed in the glass and it would project the result on the other side. Imagine large mirrored solar panels, with sunlight pouring down on large boilers. The concentrated energy from the sun heats up the water, which causes turbines to spin, which results in generating electricity.
to know how wavelengths work, imagine one straight line with two points. Think about geometry, when you studied lines, and how you learnt if they were finite or infinite. To the left is point A, and to the right is point B. If you don’t already know, a nanometre is smaller than a micrometre, which is smaller than a millimetre, a centimetre, a decimetre, and a metre. There is usually a scale, or increment that is used as a way to demonstrate how many nanometres you have passed before you get to the next point. Below that line, you will see wavy lines that repeat over and over as it makes its way to the end of the line. The number of repitition determines the frequency of that particular wave. Since most laser systems use red light, this would be around four hundred thirty billion cycles per second, or such in one wavelength, wel over forty-two octaves higher than sound waves. Not to mention that light is electromagnetic and sound is mechanical. The length of this wave is able to start and stop at the desired target without going too deep into the skin to where it could do more damage.
In conclusion, I would not say that all systems are suited for everybody, and that includes home systems as well. Laser hair removal is definitely becoming more popular, a lot more than electrolysis because of how easy it is to zap hairs with light and or heat. As I said before, I believe it is up to the person who is self-motivated to learn how to operate and complete the necessary guidelines to become a beautician and being able to administer treatment on themselves and on others. Many people aren’t willing to help others, as I said before, according to John Locke’s philosophy, so it is important that we balance out how selfish or how unselfish we should be.

I hope that you have found these links useful and I hope you are able to make decisions that work best for you in the future. Remember, everyone is different, but there will always be commonality between people who share the same passion.

Overview

Perhaps you are blind or visually impaired, and have found it hard to memorize the key combinations on the flute just by having someone tell you. Why not have written down into an accessible fingering chart that can be easily understood by the blind? This documentation will take you through some ways you can make your flute playing more successful. Now who says that vision is required to play this instrument? No one. No one says you have to have vision to play the flute. It is just the matter of how charts are accessible. For this documentation, we will be discussing the C Standard Flute, which can be divided into three parts and packed into a one-foot case. If you are unsure about what symbols mean, refer to the reference section of this manual.
People have been trying to make charts accessible; some books claim to have charts that have numbers, which can be easily understood. This is not the case. We are going to use a different format which is simple and is meant for the blind.

Assembly

For the first time, you may not know how to set your flute together. Follow these steps so you get to learn how to set it up. When you look at the parts, you will see a lot of different things. The springs on the body is called the Bohm mechanism. This allows keys to either move independently, or to move together. You need to be careful not destroying the mechanism and or the keys.

The head

The first thing you want to work with is the head joint. The head joint, or the head, is the left part of the flute. It has the blow hole inside. For practice, why not play a tone by blowing across the hole, like when you blow across a bottle to make a sound. If you are successful in playing the note, you may be able to play the flute once assembled. Take the head and follow the next step.

The Body

When you have gotten the head, you will be unsure as how you will put the two parts together. There is a way to tell which part of the body you want to insert the head. On one side of the flute you will feel two ring-like circles. This is where you want to put the head into. Slowly put it in, be careful not to grab the keys of the flute, and slowly turn it till the hole is aligned with the keys. You may want to angle it more towards the springs, just so you can get used to the feeling and be able to play easier.

The Foot

The foot is the last part of the flute you need to put together. This part is easy to figure out where to go since the head and one side of the body is taken. So, that leaves you with the opening on the right. To make sure you put the foot in the right way, make sure the pinky keys are facing left towards the head of the flute. Now insert the foot piece and you should have a fully assembled flute.

Before You Read

Here are things you need to know before you continue to the chart below. The symbols used will be represented in table form. This section will explain these symbols and what they are used for. Some symbols relate to music, some others are related to the new combination system.

The symbols used in music will be described below.

Name of symbol Description
C#-Db C-Sharp or D-Flat
D#-Eb D-Sharp or E-Flat</td
F#-Gb F-Sharp or G-Flat</td
G#-Ab G-Sharp or A-flat
A#-Bb A-Sharp or B-flat

The symbols are related to the new combination system and will be shown below.

Name of Symbol description
* If a note can be changed just by changing the way you blow, and keep the same fingering, there will be a * (star) sign in front of the note. Example: *G. There will be octave numbers so you can tell which octave you can go up. Refer to the harmonics table for more instructions.
TBb Thumb with Bb key. The thumb key has a little key underneath it. It looks like an upside down l.
Pinky1 the very first pinky on the left of the foot joint.
Pinky2 the second pinky key to the right of the first pinky key on the foot joint.
Roller the roller is slightly above the second pinky key on the foot joint.
Nob1 the first button-like key on the left nearest the head joint. Note: You will hardly use this key. It is used for fast trilling’ between C and D.
Nob2 the second button-like key to the right of the first key. Note: You will hardly use this key. It is used for fast trilling between C and Eb.
Left Pinky

the left pinky key is located below one of the combination keys on the body. This key has a bar-like shape. When pressed, a pad will open behind the flute.

The Chart

The chart will be given in table form, the notes on the left, and the combinations on the right for both fingering methods explained below. They will be in a table you can navigate with your screen reading software. Most screen reading programs allow you to navigate one column to the left, one row down, one column to the right, or one row up. You can also move by cell. Let us say you want to know what the combination for D is. you would get to the table, then you will go down to the third row, because the first row is the header, the part that tells you what is in each column. Move to the first column. To look up the combination for that note, you will either move right one or two cells to the right. Here are some commands used to navigate by table.

alt+ctrl+left: moves one cell one column to the left.

Alt+ctrl+right: move one cell right one column.


Alt+ctrl+up: moves one cell up one row.


Alt+ctrl+down: moves one cell down one row.



Note: this will work within a table only.

All numbers will start from left to right. If there are any keys that involve thumb and pinkies, those will be the first before the actual combination. The first two keys, which move together when you press on either one of them, will count as two different keys. The first one is not a key. All the others will be separate.

Here is a general position to hold your flute. Place your left hand index finger on the second key. Skip one key, and place your middle finger on the fourth key. You now place your ring finger on the fifth key. You should now have 1, 2, and 3. You fingers should be facing towards you. For the right hand, you skip the two keys, and put your index finger on the eighth key. Put your middle finger on the ninth key, then add your ring finger on the tenth key. You should have 4, 5, and 6. Your fingers face away from you this time. Here is how this would look to someone using the normal fingering.
2, 4, 5, and 8, 9, 10. To make sure you know you are putting your fingers on the right places, you need to know where you are going to place your left index finger, since there are two keys that move together. You put your finger on the second key, which will be 2 on the standard chart.

Flute Disassembly

To disassemble the flute, follow the steps as when you were assembling the flute, except this time you will be taking it apart. If you need to clean your flute, be sure to do each part individually. When done, put each part into its right compartment in the case if it has it. Some cases may have different compartments than others.

I would like to thank everyone who took part in this project and I hope it is successful with blind individuals. Your support will not only be help to me, but help to anyone who is struggling to learn the combinations all at once. This is a good way to sit down in front of a computer and make a simple table like combination fingering chart.
There may be some parts that you may not understand, but I have put a lot of effort to explain in great detail about how the flute works.
Thanks so much for your support!

***A note to blind and visually impaired users***

It is always a good idea to see a band instructor to make sure you are not missing anything important such as blowing differently
to make different notes. Playing the flute should not be hard if you have had experience with blowing bottles. It is the matter of you changing the way you purse your lips to change notes. To produce low notes, loosen your lips. For higher notes, tighten your lips more and overblown into the hole. Just experiment and find the best way to blow solid notes into it.

Harmonics

We would like to add another table which will describe what will happen if you encounter notes that are different when you have a fingering for a different note. This is what we call harmonics. Harmonics may sound a little sharper or flatter than regular tones just by a few microtones that they are hardly noticeable. There will be a table describing each note going chromatically just to give you an idea of what other notes you can expect when you have the fingering. We will use octaves to indicate where on the piano it would be at. Note: middle C is called C4 because it is the fourth octave. The top row will have the original notes and below that will be other rows that will contain its harmonics going up.

Original note C4 C#/DB4 D4 D#/Eb4 E4 F4 F#/Gb4 G4 G#/Ab4 A#/Bb4 B4 C5
First Harmonics C5 C#/Db5 D5 D#/Eb5 E5 F5 F#/Gb5 G5 G#/Ab5 A5 A#/Bb5 B5 C6
Second Harmonic G5 G#/Ab5 A5 A#/Bb5 B5 C6 C#/Db6>

D6 D#/Eb6 E6 F6 F#/Gb6 G6
Third Harmonic C6 C#/Db6 D6 D#/Eb6 E6 F6 F#/Gb6 G6 G#/Ab6 A6 A#/Bb6 B6 C7
Fourth Harmonic E6 F6 F#/Gb6 G6 G#/Ab6 A6 A#/Bb6 B6 C7 C#/Db7 D7 N/A N/A
Fifth Harmonic G6 G#/Ab6 A6 A#/Bb6 B6 C7 C#/Db7 D7 </A N/A N/A N/A N/A

As you see, there are many different possibilities when you are playing harmonics. You only use harmonics when you want to quickly change from one note from another without having to change fingerings. Do not get confused with normal notes. Depending on your head joint, and the size of the tone hole and instrument, some harmonics may be sharper or flatter than normal notes. We hope this gives you a good idea of how the flute works.
Good luck playing!
