Everybody knows what a thermographic camera is. Movies as “Predator”, the formula 1 broadcast, etc. have helped people to know this technology. CARTIF has been using it, during last years, in construction and infrastructure inspection.
My intention is not to tell you again, what everyone already knows, but talking about some myths and misconceptions that people have regarding its use.
Thermography is based on that any object with a temperature above zero kelvins emits infrared radiation, which is not visible to the human eye. This radiation depends on the object temperature, thus knowing the said radiation; it is possible to obtain the temperature.
A thermographic camera not only acquires this radiation (emitted radiation), but also the reflected and the transmitted radiation. Moreover, there are other parameters beyond the object temperature involved, so the temperature determination is not easy.
Thermographic camera have software which is able to calculate the object temperature in a transparent way to the user. If the operator relies too much on the said software and he doesn’t know well what he is doing, then issues might appear. A non-experienced operator may make some mistakes. In this post, we would like to clarify some misconceptions about thermography that general public has:
1. Thermal imaging cameras can see below the surface of a target. FALSE. The camera only sees the surface of a target and calculates the temperature
2. All types of materials can be easily measured with thermal imaging cameras. FALSE. The temperature information is given in the emitted radiation, but the imager also “sees” the reflected and transmitted components. Most materials are opaque to infrared, so we can usually ignore the transmitted energy. However, many materials (with low emissivity) reflect infrared radiation, thus these materials are difficult to be measured using a thermal camera.
3. Thermal imaging cameras should never be used in the daylight. FALSE. Infrared thermal imaging cameras do not detect visible light. They are only sensitive to infrared radiation, but it is easier to control reflected radiation at night, so it is advisable doing thermal inspection during that period of time.
4. Knowing the emissivity of the inspected object is not necessary. FALSE. This is the most important factor the camera must know to correctly calculate the temperature.
2. Detection of tiny motors in pro cyclist bikes Femke Van den Driessche, one of the favorites at the Under-23 Women’s World Championships in Belgium, was found to be racing with a mechanical motor this past January by the UCI. This is known as the first mechanical doping in cycling history.
3. Orthopaedic diagnosis Researchers at UPM confirm the usefulness of infrared thermography (IRT) for detection and early diagnosis of orthopaedic injuries.
A research group of Thermography Unit from the Faculty of Sciences for Physical Activity and Sport (INEF) at Universidad Politécnica de Madrid (UPM) in collaboration with CEMTRO has carried out a study to establish the capacity of infrared thermography (IRT) to discriminate injuries and to evaluate its applicability in emergency trauma scenarios.
Results show that this technology is a great support tool to correctly identify the presence or absence of injuries in a particular body part.
4. Pest control Some tests have concluded that it is possible to use thermography in order to pest detection, due to the correlation between the presence of insects and humidity. Furthermore, some anomalies detected on thermal images might be caused by some insects such as termites.
5. Breast cancer prevention using thermography This method is based on detect temperature changes in thermal images. Cancer creates blood vessels when it starts to develop. This process, which is known as angiogenesis, produces heat, so a thermal camera could detect this heat long before cancer can develop.
In my last post, published last week, I made a collection with the most interesting definitions of “Internet of things” or this “connected world” accesible for everyone without discrimination because of economic, social or functional diversity reasons.
At the sprint by connect everything and everyone, in the disability world, the called: “connected home” and orientation and mobility are de winner. These two aspects make life easier to people with disabilities.
In the framework of the “connected home”, the options of applying Internet of Things in the improvement of the quality of life are very spacious. Here, there are some examples:
• Philips Hue lighting system eases the communication between people with hearing disabilities, using lights to notify the person different signs and sound warnings that they may not listen. This system provides an open software platform, which facilitates its use from external applications adapted to each user.
• Brands such as Miele and Bosh announced the inclusion of intelligence and connection with smartphones in their appliances, both for the same control to offer other types of services (recipes, shopping list). Control of electrical appliances to drive, even voice, can be a big advantage for people with motor difficulties, because the use of the conventional controls could be a problem for them.
• The project SANDS(CARTIF) offers the possibility of the electrical appliances to adapt to the tastes of users automatically. Users only have to express their opinion. Appliances from users with similar profiles, communicate with each other to share recipes that are combined by the machine itself according to each user. SANDS, as in the previous case, allows the configuration and commissioning of electrical appliances from a network application. Automatic adaptation of the recipes could help people with memory problems, or cognitive disabilities to use appliances according to your tastes without having extensive knowledge of the commands.
To facilitate mobility and orientationwe have projects such as:
• AT&T and Permobil wheelchair, with wireless. Users share information about their status and situation through a secure cloud. You can also modify aspects like the position of the chair.
• A “Search for parking” systems, as the Viarium Technology, provides information to people with disabilities related to parking.
• Danok of Konectik is an application that uses iBeacon sensors and technology to provide information about the environment. This application is especially useful for blind people and people with cognitive disabilities.
• The Aditium Kango project, using cards NFC for tracking schoolchildren during their route to school. This project can also be useful for older people and people with cognitive disabilities or mental illness.
• The connected headset, Oticon Opn, uses Wi-Fi connectivity and recipes based on TWITTERFEED (IF This Then That) in addition to the traditional functionality, to allow deaf people can set it up to receive alerts such as a bell, or the activation of a smoke detector.
In short, we can see that road to “interconnection of all” can be closer thanks to advances in the IoT.
Nikola Tesla was a visionary engineer and physical of the 19th century. He devoted much of his life to wireless energy transmission, as have done with radio. He was the first that imagined a connected world which he described with these words: “Anyone, at sea or earth, could receive news or particular messages from anywhere in the world, with a simple and inexpensive device in your pocket; the Earth would seem to an immeasurable brain, capable of emitting a response from anywhere”.
The now called Internet of Things (IoT) is not a big step toward “immeasurable brain”? For those who are dedicated to new technologies, should we be motivated in order to not excluding anyone from this connected world, either for economic, social or functional diversity reasons?
“Internet of Things” is an expression that today has many descriptions, but we can say that is a term invented in 1999 by Kevin Asthon, co-founder of MIT and creator of a global standard system to RFID and others sensors. He used the IoT term to describe a system where Internet is connected to the physical world through ubiquitous sensors.
One of the most formal descriptions belongs to Cluster of European Research Projects (IERC, 2009): “Internet of Things (IOT) is an integrated part of Future Internet and could be defined as a dynamic global network infrastructure with self-configuring capabilities based on standard and interoperable communication protocols where physical and virtual “things” have identities, physical attributes, virtual personalities and use intelligent interfaces, and are seamlessly integrated into the information network”.
Recently, Diego Soriano (CENTAC) described IoT concept in a more friendly way: “IoT is the technology that allows using joint, simple and cheap form, many electronics elements connected to the Internet”
If we combine these ideas with these technological aspects: • The large number of available sensors and wearables and in design phase. • The use of technologies such as Big Data and Cloud, to analyze, management and store generated data by these devices.
IoT provide enough elements to create products and systems capable of making our lives easier. They are able to interact with the world around us without having to connect to it via cables (alerts in our smartphones, tablet or bracelet from others devices, ability to interact with appliances and security elements in our home from a different location, …). As we will see below this “make our lives easier”, IoT can be especially useful and meaningful for people with disabilities and can imply an advance in their independence.
On the one hand, the general products existence provides application in different fields to different collectives, and, on the other hand, we have specific solutions for disabilities people that, as we always say, they will evolve by quality life to everyone. Compare it with the evolution of accessible architecture.
The following week, we will go on analyzing the different applicances of IoT in the dissability world. In addition of the “connected home”, we will see some specific examples which are already in the market.
We cannot speak about Mediterranean diet without the presence of olive oil in our dishes. This fruit juice plays an essential role in the gastronomy of our country.
Extra virgin olive oil, virgin olive oil, olive oil, olive-pomace oil…all of these products are obtained from olives, each one of them has their characteristics, but what differentiates one from another and how we can choose it?
The process of olive oil production, physico-chemical parameters and in the case of virgin oils, the sensory quality (evaluated with an expert taster panel) are used to classify the olive oil.
If we speak about tasting or sensory analysis of a product, it can think and not without reason, in a subjective process and under many errors in their implementation, ambiguous or subject to interpretation expressions. But sensory analysis is a scientific discipline used to evaluate the organoleptic characteristics of food, and it has been used for many years like a method to measure, analyze and understandhuman reactions to the organoleptic characteristics of food by the senses. Data from a sensory analysis are evaluated by a panel of tasters trained for it and are statistically treated in order to minimize errors and make objective results.
In the case of tasting olive oil for classification as extra virgin olive oil, virgin oil or lamp oil, it is carried out by a panel of experts, which will also be authorized by bodies of the member states, to carry out official control of the country.
The tasting test is carried out under a specific regulation developed by the International Olive Oil Council, in which the tasters follow a profile sheet with positive attributes and some negative attributes that are valued on a scale of 10 cm. The tasting test is carried out in a glass for oil specific and the oil samples shall be kept in the glasses at 28ºC±2ºC throughout the test, this temperature has been chosen because it makes it easier to observe organoleptic differences than at ambient temperature.
In the method for the organoleptic assessment are detailed the number of samples, amount of oil, explanation of vocabulary, etc.. to assessing the virgin olive oil.
The positive attributes that are valued in oil are fruity, bitter and pungent, these attributes will depend on the variety of olive, the degree of maturity of the same, and the time they have been harvested.
The negative attributes are determined by the following attributes:
1. Fusty/muddy sediment Characteristic flavour of oil obtained from olives piled or stored in such conditions as to have undergone an advanced stage of anaerobic fermentation, or of oil which has been left in contact with the sediment that settles in underground tanks and vats and which has also undergone a process of anaerobic fermentation.
2. Musty-humid-earthy Characteristic flavour of oils obtained from fruit in which large numbers of fungi and yeasts have developed as a result of its being stored in humid conditions for several days or of oil obtained from olives that have been collected with earth or mud on them and which have not been washed.
3. Winey-vinegary. Characteristic flavour of certain oils reminiscent of wine or vinegar.
4.Acid-sour. This flavour is mainly due to a process of aerobic fermentation in the olives or in olive paste left on pressing mats which have not been properly cleaned.
5. Rancid Flavour of oils which have undergone an intense process of oxidation.
6. Frostbitten olives. (wet wood) Characteristic flavour of oils extracted from olives which have been injured by frost while on the tree.
On the same tab tasting the taster may indicate other negative attributes such as a heated or burnt, hay-wood, rough, greasy, vegetable water, brine, metallic, esparto, grubby and/or cucumber.
To be considered extra virgin, the oil shall not have any defect and the fruity attribute must be greater than 0; if the oil has a defect (less than 3.5 on the scale) and the median of the fruity attribute is above 0, would become a virgin oil; and if the oil was very defective in sensory quality is classified as lampante virgin olive oil and should be refined for consumption.
In most cases as consumers, we will not be able to distinguish all of these attributes, but it’s all about training your palate, have good sensory memory and taste, taste and taste different oils. And whenever we want to enjoy quality oil, choose an extra virgin olive oil, where we can appreciate the variety of olive, the time of harvest the fruit, nuances of smells and flavors of the harvested area. Not all olive oils are the same … taste, let’s try and enjoy the liquid gold.
The first post about Industry 4.0 indicated the need for key technologies that would make possible the 4th industrial revolution. These key tehcnologies have been called “digital enablers“. Each industrial revolution has had its “enablers”. The first one was made possible by inventions like the steam engine or mechanical loom. The second came started with breakthroughs like electricity or the car assembly line. In the third, disruptive technologies such as robotics, microelectronics and computer networks made their debut.
This post is intended as a shopping list to review those technologies considered highly relevant and key for this fourth revolution. Each brief description is linked to an extended information covered inside our Blog. In next posts we will complete the descriptions to have an overview of the full range of technologies:
Virtual / Augmented Reality: provides information to the operator adapted to the context (e.g. during a maintenance operation) and merged with their field of view.
IoT: internet for virtually any object, in this case, the ones we can find in a factory: a workpiece, a motor, a tool…
Traceability: seeks the monitoring of manufacturing operations (automatic and manual), products as well as the conditions that were used to create them (temperature, production speed…)
Predictive maintenance: an optimized way to perform maintenance in order to avoid unexpected stops and unnecessary waste because of periodic maintenance operations.
Artificial vision: provides the production process visual context information for quality control or assistance in manufacturing (e.g. automatic positioning of a robot to take a piece).
Big Data: generates knowledge and value from manufacturing data as well as other context data (e.g. demand for similar or related products)
3D Printing recreates of a three-dimensional copy of: existing parts, spare parts or prototypes with the same or different scale for review or testing.
Cloud Computing leverages on internet computing resources to undertake storage and processing of large data sets (e.g. Big Data) without the need of investment in own IT infrastructure.
Cybersecurity as physical and logical security measures used to protect infrastructure (manufacturing in this context) from various threats (e.g. a hacker, sabotage, etc).
Cyber-Physical Systems as any complex system consisting of a combination of any of the above technologies seeking improved performance, in this case, of manufacturing.
The strength of these digital enablers is not in their individual features but in their ability to come together. We as engineers love to look for the latest technology trend and then found a problem or area for its application. But to succeed in this revolution, it is necessary to face real challenges within the factories, using innovative solutions, and why not, combining several of the digital enablers shown above. Moreover, this terminology creates a common framework that facilitates a dialogue between technologists and manufacturers for undertaking successful projects seeking to optimize the factory.
If we think, for example, to optimize maintenance operations in a factory, the “predictive maintenance” will be one of the first enablers that comes to our mind. Also, this technology solution will benefit from a connection to a “Cloud computing” system where sensors’ data coming from different factories will be analyzed generating better diagnosis and predictions of the production assets under monitoring. In this type of cloud solutions, however, the security of information transmitted must be ensured via appropriate “Cybersecurity” mechanisms. We will, therefore, generate an Industry 4.0 cybersecure, multi-site, predictive maintenance solution.
The list of presented technologies doesn’t intend to be final. Also, technological evolution is continuous and incredibly fast. Like we have mentioned, the combination of different digital enablers generates a wide range of industry 4.0 solutions. In next posts we will discuss more scenarios where digital enablers can answer to different challenges in manufacturing.
We could read some time ago, as a headline in a national newspaper, that the Chairman of Repsol, Antonio Brufau, literally stated that “It is false that the electric car has zero emissions” and “(…) emissions must take into account not only CO2 emitted by the vehicle, but those produced during manufacture“. With this headline and without realizing, the Chairman of REPSOL was advocating for considering the life cycle of a product to make environmental self-declarations. The fact is that this generalized doubt about the relationship between the electric car and the CO2 cannot lead us to think that it is not one of the most environmental mobility options because it is, what happens is that we should be meticulous when it comes to talk about the environmental performance of products.
One of the first examples of using life-cycle thinking assesment (LCA) in the late 60s, in the USA, when Coca-Cola® decided to explore alternative containers besides the glass bottle through this approach. And this concept arose from a very logical way, due to the emerging companies’ demand for distributing environmental loads, nobody liked being the most pollutant. Companies began to ask about an extended responsibility in this regard and through methodologies such as Life Cycle Assessment (LCA), one of the most internationally recognized and accepted methods to investigate the environmental performance of products throughout their life cycle, it could be verified that the associated environmental impacts with the manufacturing stage were not the most relevant in some cases.
Let’s see an example to summarize this issue. Imagine a conversation between Mary Ecological and Mary Nosy:
Mary Ecological: “Have you seen the garlands I have placed for the party? they are made of recycled paper because I am an ecological woman, you know“ Mary Nosy: “They are lovely, where did you buy them?” Mary Ecological: “In a Chinese online shop, extremely cheap”
A Life Cycle Assessment (LCA) applied to these garlands would probably have confirmed us that Mary Ecological is attributing to herself a label that is not true. To buy a product in China can cause that an item made of recycled paper may have a hidden environmental price that is “disguised” using a more environmentally friendly raw material within the manufacturing process. And from the moment we are free to choose what we buy, as consumers, we are sharing the environmental responsibility with the industry, let´s keep this in mind.
When a company asks for what is the environmental profile of its product and / or process, CARTIF always advises to apply this methodology because the obtained results are a detailed environmental picture of the life cycle of its process, product or service (suppliers included), with the consequent opportunity to identify critical points and reduce costs, both environmental and economic. We have been able to check it many times in many of our projects. It doesn’t matter if we are a consumer or a product manager, to take a life-cycle approach to the environmental impact of the products we are acquiring, producing or selling, is essential to make decisions and to put in clear terms our environmental performance.
For this reason, the Chairman of Repsol said the principle of only considering the stage of use in an electric car to confirm that it does not emit CO2 is incorrect. Although it is perhaps the most significant phase (in fuel-consuming vehicles too), the assessment must be extended to its life cycle which, obviously, includes CO2 emissions from electricity production. Strictly speaking, we should either clarify that the electric vehicle does not emit CO2 during the stage of use or apply the LCA considering its life cycle (CARTIF has already done it) so that, based on the results, to generate environmental headlines.
We love the environmental assessments well done and undertaking rigorous environmental claims. Ask us and we’ll tell you how to do this!
