Monitors sleep by smartbands and mobile applications

The sleep monitoring is one of the complaints that most employ smart bands to attract our attention but is certainly the most misleading because of the complexity to determine it from devices or whatever “wearables” translate “wearable / smart accessories”.

We have seen in the first part of this post different types of measurements that can make smartbands in physical activity. Now we look to see what can offer regarding MONITORING sleep.

Polysomnography against smartbands for registration Sleep

Attempting to monitor the time and sleep quality using devices such as smart bracelets is almost like trying to measure blood pressure and pulse just taking our fingers. Astandard polysomnography is done by recording at least the electroencephalogram (EEG), electrooculography (EOG) and electromyogram (EMG) of the chin . Also you can add other parameters such as registration of thoracic and abdominal movement, electrocardiogram, pulse oximetry, oxygen saturation, video monitoring, noise assessment to detect snoring or electromyogram lower limb depending on the purpose of the study. We

have two types of meters smartbands sleep by those who do it for  movement  and those who do it for information  multisensory . None include any of the 3 minimum records required by polysomnography, for them the results that we expect should not be too ambitious, though not all have to be entirely useless. I’ve tried both types of bracelets, but I have not had a chance to compare between them or with real polysomnography recordings, although others if they have done, let’s see ….

Monitors sleep by movement

Initially monitoring dream started with mobile applications that were put under the pillow and through an average application the movement doing in bed at night.Simplified mobile interpreted froma if you’re still’re asleep and if you move, is to wake up or do not have peaceful sleep …. Something completely inaccurate and that correlates very poorly with reality and with polysomnographic recordings. Also they do not give information about the quality and the phases of sleep. This type of monitoring is then extended to devices such as motion sensors under the mattress or pillow, cameras for the nightstand that monitor our movement and / or breathing.

Currently they used as a lure to smartbands as Fitbit, Up 2 and others. Do not befooled, information on sleep quality that give these enabled device including the combined records of heart rate  does not correlate with reality even remotely  and can induce excessive concern the quality of sleep if we make many minutes of fitful sleep. Only you can trust about the number of hours that tell you that you sleep (and I say more or less because not very long awakenings good measure). If you sleep enough hours and you wake up rested you do not have sleep problem whatever it says your SmartBand.

According to this little experience of this specialist in sleep neurologist who compared the medical record by polysomnography (the most accurate and the only one made by a device doctor), with several smart bands based on movement (older versions of Up and Fitbit) and a device with the clock multisensory information Basis Peak. The results were:

source Huffingtonpost

All the devices detected motion or movement combined with heart rate were too poor to evaluate the type of sleep and are most sold and advertised !!!

Instead the only one of the evaluated that used multisensory information, the smart watch  Basis Peak , gave a much more precise (not perfect) information on the type of sleep and awakenings but by no means can replace polysomnography, much less.

therefore these devices all we can hope for is to inform us of few hours spent in bed asleep in theory, and the approximate number of awakenings . Nothing more, do not give importance to things like fitful sleep or terms because not correlate with anything.

Sleep monitors based on multisensory information

These devices have several sensors that provide information and includes multisensory,  heart rate, motion detection, temperature and galvanic skin response that measures the sweat and moisture of the skin. I know there are only 2 activity bracelet  Up3 and Up4 Jawbone  (different from the previous chart was an older model), and the clock  Basis Peak . They are the only ones who approach detection sleep more precise without being accurate, automatically detect when we slept, provide information on the duration of sleep and try to tell the time in each sleep phase (REM, light, deep). Basis Ell also includes a graph of the movement we make, temperature and galvanic skin response searchable unlike Up3 and Up4. As you cansee not include records EEG, EOG or EMG polysomnographic studies, but still seem to make an approach to the stages of sleep and a better record of awakenings and time asleep.

Personally this month I tried the two together with the Fitbit Charge HR based only on the move. Fitbit Charge HR (and Charge 2)  gives a simple report and that serves almost nothing. Instead Up3 and Basis Peak apparently give a more precise information and try to differentiate REM sleep, light sleep, deep sleep. I could not use both at the same time so I do not know if they resemble in their results, something that would be nice to compare them with a polysomnographic recording.

What I have noticed is that both multisensory devices tend to interpret that I fell asleep earlier than he did (if you do not move much in bed can be half an hour awake and tell you were asleep), to detect less awakenings of real (for the same reason I suppose), and calculate pretty bad the duration of the same, several times I spent an hour and awake of the time interpreted that I had gone to sleep or REM sleep was even.
Anyway a general level I think we can target where we walk, how long we sleep and number of awakenings, at least the most important, all those who are too short not influence our quality of sleep, and have the potential to a check rudimentarily worse if we sleep when we are stressed, when we drink alcohol in the evening, or sleep better when we exercise for the day, do meditation or are on vacation. L os sensors multisensory improve enough dream interpretation regarding the motion, but still far from being accurate  at least in my experience  (and certainly not can be considered medical devices, nor intended), but if you want one is obvious you can only choose one of these two and to forget the rest of smartbands, apps or smartwatchs.

Other personal devices to monitor sleep

There are other devices designed to try to measure the quality and quantity of our sleep, from tape to put on the head, helmets with sensors of brain electrical activity, cameras watch us at night or plates are placed under the mattress or pillow. most accurate .. little but I have not had a chance to review them or try them, but remember, if based only on the move you can expect little from them. I hope to complete this task in the future with information about them. I leave you with the 3rd and last part of this entry. For more details visit fitpro.

The film Argentina on renewable energy project began using renewable energy

The animated feature international recognition that covers the main concepts of clean energy was exhibited at three locations in the Santa Fe. This time the projections were made outdoors thanks to the provision of photovoltaic panels. During spring functions will resume within the province.

With free admission, during the Wednesday, Thursday and Friday last week was screened at the santafecinas towns of Santa Isabel, Elortondo and Venado Tuerto, respectively, audiovisual production designed for children and adults about the benefits and importance of the renewable energies: “The Journey of Gaia”.

This is a film produced by the Undersecretariat of Renewable Energy Ministry of Energy and the Ministry of Innovation and Culture of the Province of Santa Fe that seeks to raise awareness about the urgency to change our energy consumption habits and bring the public the concept of renewable energies, environmentally friendly.

While the animated feature film was released mid last year, receiving in November SUN GOLDEN PETIT FICMA prize in Barcelona, Spain, as part of the International Festival of Environmental Film, again surprised after the novelty of his projection outdoors by photovoltaic panels and a battery bank.

This initiative is carried out by Cinergia Audiovisual Productions and is called Eco Cinergia. However the idea of carrying out outdoor events thanks to the use of solar energy is nothing new for this company founded in 2008 and has already made over 250 functions allowing more than 150,000 people enjoy this experience.

With regard to the continuity of projections “Gaia’s Journey”, from the Ministry of Energy report that activities will resume once you pass the winter, because it is outdoors events. It is estimated that during the spring to resume activity in northern localities of the province of Santa Fe. You can watch on putlocker.

An energy audit to reduce consumption of SEO / BirdLife

An energy audit as he has done Ecooo for SEO / BirdLife is a descriptive document and, at the same time practical. In addition to pointing ‘leaks’ also it offers solutions with a plan of measures ranging from simple and quick to the most costly in time and effort. The investment made to improve efficiency recovers thanks to  savings in electricity bills . The head of the building can consider an investment plan and calculate times in which what steps it will be taking and what savings will be receiving to have a return for the effort undertaken.

In the case of SEO / BirdLife, we will opt immediately for a series of measures that will allow reducing consumption by 25%, Asun Ruiz confirmed after examining the energy audit report. Install motion detectors for turning on and off lights, change the system of ballasts for fluorescent to a more efficient lighting, shading the terrace, adjust the operation of heat pumps and cooling and not allow electronic devices remain on  stand  by , because they consume even if they seem off, will serve for sensible savings of a quarter of the energy. And all thanks to a not very high economic investment.

The energy audit also a pleasant surprise in store. Our old building Melquiades Biencinto,  a brick building in 1925 , has obtained a general certification D, “a category that is above the average of conventional constructions” as explained Rodrigo Irurzun and Juan José del Valle, technical of Ecooo who have performed the analysis. This is because when SEO / BirdLife moved to this office conducted some reforms that improved the energy efficiency of the property and also because the implementation of Environmental Management System has been further enhancing our use of energy.

Explained and Ramón Martí, director of territorial coordination of SEO / BirdLife and responsible  environmental management in our NGO : “Remember that SEO / BirdLife pioneered environmental responsibility when in 2009  the first Spanish conservationist NGOs in getting AENOR certification  for its Environmental Management System ISO 14001 “standard. With such measures we ensure that efficient use of resources such as water, energy and office equipment is made and properly gestionaan waste and emissions, said Martí.

The bet for years for good environmental management of SEO / BirdLife has taken a le ap forward to insist on energy saving. First, we conducted a survey to members  in which the vast majority requested Advised to put renewable and almost 90% of them voted for solar as the most appropriate.With this social demand in hand, in 2013,  we signed an agreement with Ecooo to develop responsible renewable energy and to promote the transition to a cleaner and sustainable energy model. Therefore, we become producers of solar energy becoming an “action” in the  Solar Wave ~ Social Lebrija (Sevilla) . We are so  c otitulares of a photovoltaic plant  located on the roofs of schools and other municipal buildings in the Seville town. This also show our support for solar energy on deck, an example of  renewable energy charge based on consumption and decentralized production of electricity and minimal impact on the natural environment and that is the only type of photovoltaic development the betting seo bangkok, a company with a high cooperative component and environmental commitment.

The energy audit is just now making the next step in this agreement with Ecooo energy to reach excellence. And there is a final breakthrough that we are willing to give, as is the placement of photovoltaic panels producing electricity in our own headquarters. However,  the latest regulations of the electricity market and the energy system approved by the Government , which put enormous legal and economic barriers to consumption, are hindering this to take place. Our struggle is now trying to reverse these retrogressive Administration laws that are preventing democratization and improving energy.

How much power does Internet?

Internet is not only for pr0n, but we also facilitates life in a tremendous way. But surely you’ve ever stopped to think how much energy Internet.

 In dod approved 8570 baseline certifications they have some figures, and the truth is that it is a lot. Internet depends on a steady flow of electricity to operate not only our computers, smartphones and tablets, but more importantly, the servers. .

Servers are large computers that is responsible for receiving requests and send responses, either by sending the required data to another server or you have them.

The problem of energy consumption Internet

How much energy Internet

Work at all hours, and process information constantly: in 2013 already processed 28,000 GB per second , and this figure has only risen over time, but fortunately also have become fashionable other practices such as cloud services that reduce the consumption by up to 86% compared to what wouldconsume if all businesses had their own servers.

How much energy Internet

Many data processing involves high consumption. Internet in 2011 and accounted for 2% of global electricity consumption . But does that mean they are always processing and spending? No, actually a good number of servers do absolutely nothing, or only reach 10% of capacity, waiting for the time whenyou get a lot of requests.

In fact, much of the Internet to keep power consumption does not come from the servers, but what surrounds it: the ventilation . Server farms can reach temperatures that damage the processor, so it is vital to implement air conditioning systems to prevent it .

The result is that in the US alone, it is expected that by 2020 consumption of 140.000 million kilowatt hours each year . A figure that should take into account as Internet use also extends to developing countries.

ASO: The SEO of Applications

If you do SEO web, in mobile apps you have to do ASO.

How many apps you have installed on your smartphone? And in your tablet? How do you meet?

According to SEO specialist, more than 63% of searches come from facilities in major shopping apps: App Store and Google Play.

And how do we position ourselves for searches performed by users? The answer is ASO .

ASO stands for app store optimization and becomes more or less the same as the SEO web. ASO is the process of optimizing an app in order to get the first results appear when a user searches app stores. The more visibility you have a mobile application in the stores, the more likely to be found by users and therefore more likely to get downloads.


SEO, as we know all (or almost all), is the set of techniques that can be applied on a website so that it is positioned in the top search results on major search engines (Google). The ASO is based on the same concept, but led the mobile application stores.

The ASO process is like the SEO process: do not end with a single implementation. The process consists of ASO Keyword research, optimization of landing (record) of our app and monitoring. And back again!

Just as there are some SEO factors: on-page and off-page, we must work for the SEO work, there ASO factors: on-metadata and off-metadata , you also have to work to reach the top in App, said the brisbane seo expert


  • App name : The name of an app should contain the main keywords why we want to be found and also be striking.
  • Description : The description of an app, in the case of Google Play, you must include keywords (without spam) and, in the case of Apple, should be used as a marketing weapon to captivate users.
  • Keywords : For Google Play do not have field “keywords”, while Apple itself. Use it with care!
  • Developer Name : That the name of the developer include keywords is good. In addition, the old developer is also an important factor.The most senior developers have more “strength” to rank.
  • Icon : The icon does not affect directly the ASO. However, it is essential to draw the attention of users. It is usually the first thing fixing. Hire a good designer!
  • Screenshots : As with the icon, screenshots chosen for the tab will not cause an app better position, but a good selection of screenshots that users will “die” for installation.
  • Facilities : The more facilities and faster we get, the better positioned it will be the application. There are different ways to get facilities: own channels, press releases, reviews on websites / blogs, marketing campaigns app display networks, social media, influencers, email marketing, etc.
  • Uninstalls : It ‘s good that users install an app. What is not so good it is that the removal ratio is high. It is an indicator that the product (app) is not as good as it should be. Ratings and Comments: The famous stars! The positive feedback directly affect the ASO of an app.But beware, do not buy ratings! That could be understood as “Black Hat ASO” and is punishable by Google and Apple.
  • Social signals : In the case of Google Play, the more +1, the better. In the case of Apple, the more “likes” of Facebook, the better.
  • Linkbuilding : Gossips say that in the case of Google Play, the links you receive an application URL improve ASO … Is it true?


The ASO is a new discipline within digital marketing. However, few companies take this into account in their app marketing strategies. For this reason, we carry out a good ASO strategy will enable us to strike a blow on the table and apart from the competition .

Is a battery for e-cigarette safe?

You probably it has seen on the News , or seen it on the Internet. Stories of a man to the to your electronic cigarette you exploded in your hands. More recently, have emerged stories approaches of batteries type eGo fire or explode while they are loading. And lately is already coming to the dissemination of videos clearly false. Our batteries, our essential electronic cigar accessories, are based in the technology of ion of lithium. And due to the nature of the chemical, batteries of lithium rechargeable possess risk inherent, there is no doubt.


Technology of the battery not changed long during the years, but instead see the same batteries rechargeable in formats different more compact , and packed more firmly.This no only creates a battery more strong, by density chemical energy, but also more dangerous. The cigarettes electronic non the unique devices susceptible of explosions of its battery. Laptops and mobile phones also is they burned and explode its is makes them inappropriate.


A battery defective or used incorrect can overheating. This can do your cells from deteriorating and establish a chain reaction with other cells that make the battery explode. In a process called to thermal barrage, batteries of lithium can swell or exploit ultimate If not is take measures quickly.


They are electronic cigarettes nor its accessories. They are the batteries.


The danger inherent of the battery of lithium is the potential to ignite a fire. The l ITE has a high potential electro-chemical and so is use in many battery common. Thelithium has a bass weight Atomic, that reduces the mass of batteries. However is produces much energy while is move to the electrode, together with a large amount ofheat. Much more compact is the battery, higher it will be the chance of that overheating.


As all best electronic cigarette in the UK accessories must be careful when choosing them, various devices have outputs of power different and so require Accessories and modelsspecific it battery. Using a battery is too small for a particular device increases the risk of ventilation, overheating and can be reached at exploit.


While the lithium is extraordinary for the manufacture of cells electric, This makes that is deep reagents. The lithium is a Metal alkaline addition of sodium, andpotassium. These components are deep fuels and reagents up to the point that getting a pair of grams in water haran blast. So when it heats an lithium battery, the lithiumin it can speed the decomposition of the different units producing chain reaction.


As regards the cigarettes electronic, the explosion of batteries are they attribute to error user, no a malfunction of the devices or accessories by themselves.
For example, a battery will not be under the same requirement depending on the resistance of our cigarette. Resistances of electronic cigarettes are a fundamental part in the equation of power and consumption, wrong calculations can end badly.
As we said that batteries are prepared for the demands of cigarettes electronic and vapping low resistance or high power, but we must be aware that they are not harmless accessories.


These are some Tips from Security Basic for the use of a battery for e-cigarette:


  • For devices with battery fixed (eGos), only use the accessory charger provided by the manufacturer.
  • Not oncharge batteries.
  • Before of use mods mechanics and repairable, learning approaches of Ohm’s law.
  • Not stack battery in mods mechanics.
  • Be sure to of use the battery suitable for your device.
  • Not leave unattended batteries in cars, the Sun u other places where can be submitted to high temperature.


If ever listen to your battery making a noise whistling Remove the battery of the load or vapeo device and put it in a place insurance up which is cool. Get rid of it. Byou aterías tend to explode bass high pressure, no only because is are using in a cigarette electronic. 
In short the batteries are all insecure our common sense allows us to, do stupid things with them, is dangerous. Normal use allows safely vapping.

A New Perspective on Energy

Integrated systems for cooling, heating and power (CHP) for buildings incorporate multiple technologies for providing energy services to a single building or to a campus of buildings. Electricity to such buildings is provided by on-site or near-site power generators using one or more of the many options: internal combustion (IC) engines, combustion turbines, mini- or micro-turbines, and fuel cells. In CHP systems, waste heat from power generation equipment is recovered for operating equipment for cooling, heating, or controlling humidity in buildings, by using absorption chillers, desiccant dehumidifiers, or heat recovery equipment for producing steam or hot water. These integrated systems are known by a variety of acronyms: CHP, CHPB (Cooling, Heating and Power for Buildings), CCHP (Combined Cooling Heating and Power), BCHP (Buildings Cooling, Heating and Power), and IES (Integrated Energy Systems).

CHP systems provide many benefits, including:

  • Reduced energy costs
  • Improved power reliability
  • Increased energy efficiency
  • Improved environmental quality
The Southeast CHP Application Center (CHPCenterSE) was established in August 2004 for the U.S. Department of Energy (DOE). Its mission is to provide application assistance, technology information, and educational support in the Southeast United States.

The objective of this site is to provide you with information on CHP for buildings to facilitate your decisions relating to these systems. Information on the site has been organized to address anticipated needs of various user groups. Click on a link of your choice to learn about some of the basics, benefits, success stories and much more.
