Fanless Embedded Computer How to Used Fanless PC

0

As a quick answer to what is an embedded computer, we can say that it functions as part of a complete device rather than as a standalone machine. Such computers perform highly specialized tasks. Digital signage, industrial automation, and in-vehicle computing are just some of the applications for embedded PCs.

If you think about computers, you might see something different. The first thing that comes to mind is probably fanless embedded computer a rectangular box with cords sticking out. The sides of these consumer PCs are also cut with vents to allow airflow to cool the internal components.

Computer systems have changed radically in size and design as technology has advanced. Nowadays, commercial embedded computers bear little resemblance to their desktop tower counterparts. However, perhaps even more importantly, the way in which industry utilizes computers has evolved. Today, computers are used for things that seemed impossible not long ago, such as the Internet of Things (IoT). How exactly does an embedded PC work? How does it compare with consumer-grade tower computers in form and performance?

Industrial PC vs. IoT Gateway vs. Embedded Computer

An embedded system can be defined as any computer system that is embedded into another system. As we move forward in time and technology, the embedded systems become ever smaller and more sophisticated. Embedded systems are becoming more common, from the little computers in our cell phones to the super computers used in medical implants.

Embedded computing is the combination of computer hardware and software that is incorporated into products that help with their functionality. It is closely linked to the Internet of Things (IoT), in which physical objects become connected to the network and can be monitored and controlled remotely.

Appliance PC – What Is It?

We call our products “Appliances” because many of our clients use our products to complete one specific task or operation. Creating a dedicated device to do one thing well requires very customizable, ultra-reliable hardware that can be configured to the exact requirements of the given application.

The appliance PC has the same features as an embedded PC (specialized I/O, fanless, ventless chassis, small form factor). Rather than being designed to be incorporated into another device, the appliance PC is engineered for standalone operation.

The appliance PC is the perfect solution for needing a dedicated PC to perform a single task in a high-reliability environment. The appliance PC is a self-contained computer that includes all the features and components required to perform a specific task. You plug the appliance PC into the power, network, and any other required connections, and you are ready to go.

The appliance PC is designed to be a perfect tool for performing specific tasks such as: Security / Surveillance A surveillance system with a dedicated appliance PC can be used in a number of ways. The appliance PC will do its job without the need for a monitor, keyboard, or mouse. The appliance PC is also tranquil. It does not produce the loud fan noise of an embedded PC.

Embedded Computers: What Are They Used For?

A self-contained PC that is part of a larger system is what we mean by “embedded computer” at OnLogic. In addition to data collection devices used in solar arrays and navigation equipment on NASA’s planetary rovers, our embedded computers power digital signage displays and modern interactive kiosks. You probably passed right by several embedded computers in your travels today. Perhaps you weren’t even aware of them. Thousands of devices and systems that we use on a daily basis are powered by batteries.

Batteries are the power source for many embedded computer systems. When they’re finished with their useful life, the batteries need to be replaced. This process can take several hours or days depending on the battery type. How much time is spent in a typical day using embedded computers? Let’s say you work at a retail store with an electronic cash register. Every transaction processed by the register needs to be recorded.

Your embedded computer system also controls digital signs in the store. These signs display information about the products being sold, the prices of those items, and other details about the store. The digital signs are part of the same system as the cash register. That means that your embedded computer system must constantly monitor the cash drawer and record every purchase.

A lot of people assume that home improvement is just too overwhelming to bother tackling. If you are open-minded, that isn’t true. The following article can help you achieve your home improvement goals.

If you are purchasing a home, consider hiring a professional home inspector. It is always good to have a professional and neutral opinion on the home you are interested in buying. Having a professional that is neutral will also be beneficial to both parties.

Use a porch light with a motion sensor to cut down on your electric bill. You can turn the light on manually, and on many models, you can also adjust its sensitivity. Use a

Does your vinyl floor covering have a bubble in it? If so, then pop it! You can usually cut into it to let the air out. This will make the bubble go away. After this you need to insert some glue to keep the floor sealed. Get the glue that comes inside a syringe to help you complete this job.

When doing home improvement work, one of the most important tools to have is a drill. It will allow you to make holes of different sizes so that you can screw things together, and it can allow you to drive in screws with various attachments. It’s best to have a cordless battery powered drill with at least 9 volts and 1/4, 1/8, 1/16, and 1/32 inch drill bits, and attachments for driving flat-head and Phillips screws.

Don’t buy expensive supplies. Instead, shop around and look for the best deals on home improvement materials. It can be expensive to install new flooring, and you should shop around for the best prices. Seek prices and quotes from discount suppliers and local home improvement centers.

You can change the appearance of your appliances in the kitchen more affordably than you might think. Although stainless steel is popular these days, it’s pointless to get rid of a working refrigerator just because you don’t like the color. Appliance spray paint is available in a variety of colors at any home supply store. Your kitchen can have a whole new look with just a few hours of painting.

Connecting PVC pipes requires specific PVC adhesive and PVC primer. These exact items must be used, as other types of adhesives are likely to leak. There shouldn’t be water on the outside of the pipe.

Gutters, downspouts and chimneys sometimes get overlooked during yearly maintenance and home improvements. It is vital to look at these areas and repair them if necessary. Chimneys can catch on fire if they aren’t cleaned regularly, and clogged downspouts or overflowing gutters can cause water damage.

It is important to develop a plan before beginning any home improvement project. Procrastinating until start day can be disastrous, as it can result in hasty decisions and bad judgments. The project will run much more smoothly if everything has been planned ahead of time.

If you are looking to create a sense of tranquility in your rooms, choose light and airy colors, such as light purple, light green or light blue. Use the light fabrics, such as linen or cotton, rather than dark brocades and heavy fabrics. Potpourri or scented candles can add an inviting warmth to a home.

If an older person lives with you, you should plan your house in a way so that it’s safe for them to live in. Adding some railing to the home is an example of how you can improve safety in a home. Installing bars for holding onto when walking around are also a great idea.

A lot of homes lose a considerable amount of heating and cooling through the windows in their home. By glazing your large, picture windows, you can significantly cut back on the loss of heat and cold air. Your home will be more comfortable inside, and your energy bills will decrease.

The Museum owns 482,000 pieces of art, but it also has the Musée National Eugène-Delacroix, the sculptures in the Tuileries and Carrousel gardens, and the ‘MNR’ (Musées Nationaux Récupération, or National Museums Recovery). The pieces were discovered after the Second World War and are kept at the Louvre until their real owners can be identified.

Interactive maps in French, English, Spanish and Chinese offer the best viewing experience on smartphones but are also compatible with computers and tablets. Thanks!

  1. The National Gallery

You can search, browse, and view the art on the website of the National Gallery in London, which has a collection of over 2,400 pieces. There is no shortage of art treasures with iconic works by some of Europe’s most renowned artists. The gallery offers behind-the-scenes views of restoration and conservation projects

There’s also a virtual tour of 18 rooms available via Google Street View. A VR headset from Oculus lets you explore the Sainsbury Wing, which houses more than 270 paintings you can see up close and personal.

  1. The New York Metropolitan Museum of Art

The Metropolitan Museum of Art in New York City is one of the most visited art museums in the United States. As part of its ‘Experience the Met, Anywhere’ campaign (complete with its own hashtag, #MetAnywhere), the museum has released a digital digest that gives you access to its international collection.

You will find sections such as Met Kids (which includes a video on making clay pots), Primer (to get a basic understanding of key themes and timelines), audio guides, among others. This gives you an idea of what the Met has to offer and should keep you entertained for a long time. A 360° video of the Met’s incredible architecture was highlighted for us.

  1. Whitney Museum of American Art

One of the most beloved art institutions in the United States, if not the world, is the Whitney Museum of American Art. The museum displays American artwork from the 20th and 21st centuries. It is housed in a Brutalist building by Marcel Breuer (now the Met Breuer) before moving to a purpose-built building by Renzo Piano in the West Village.

The Whitney Museum has digitized its entire collection so that visitors can view over 25,000 artworks, including photographs, films, books, paintings, textiles, and performance art. The Times They Ain’t A Changing, Fast Enough! is an outstanding work. It depicts Philando Castille, who was shot and killed by police while driving his car, by Henry Taylor, 2017.

  1. The Smithsonian National Museum of Natural History

The Smithsonian Institution, the world’s largest research and museum complex, has an excellent virtual tool. Three floors of the museum are open for exploring, including the Hall of Fossils, Insect Zoo, and Geology.

Engineered Wood Flooring of Different Types with Advantages

0

It is very likely you have heard of “engineered flooring” if you are in the market for a wood floor. But, how does engineered engineered wood flooring wood flooring work, and why might you want to consider it? Our next topic will examine why many people prefer engineered wood flooring over solid wood flooring when considering a wood floor.

Designed and built according to scientific principles is the definition of Engineered in the dictionary

Engineered flooring is built and designed to meet specific requirements. Wood that has been grown from a tree is no longer a natural floor. Here’s what that means.

What is Construction of Engineered Wood Flooring

Decorative layers must be real wood in order to qualify as engineered wood floors. While laminate flooring has a printed decorative layer, engineered floors can only have a natural decorative top layer. Laminate floors are made from real wood. A core of HDF is made from wood chips, but the decorative surface is not made from real wood.

It is possible to use different types of real wood for the decorative layer. A thicker top layer typically has a longer lifespan and can be sanded more times. However, it is also important to note that a thicker top layer can add to the costs.

The core board is the next component of engineered flooring. This is the foundation for the decorative layer to adhere to. The core board is very important. It provides strength and stability to the overall floor. The core is made from materials that are considered more stable than solid wood flooring when exposed to changes in moisture and heat. There are various types of core boards used in engineered wood flooring.It is arranged with total thickness first and then tops layer. The total thickness of the panel is 18mm, and the top layer is 5mm of real wood.

Different Types of Engineered Floors

The most common type is a multi-ply engineered wood floor. Engineered wood floors have a similar feel to solid wood floors. This provides extra resistance to cupping and overexpansion. Normally, the thickness is between 13mm and 20mm. However, stability is ensured in wide widths up to 350mm due to the extra strength in the plywood core.

Three-ply engineered flooring is another popular option. Despite its excellent resistance to cupping and overexpansion, this product feels fantastic when installed. Typical total thicknesses range from 12-18mm. Our recommendation is to use 3-ply cores for boards up to 200mm in width. Unfortunately, the core is not as strong as a multi-ply core and can be unstable when installed on wide plank wood floors.

Engineered flooring with HDF cores is less common. However, their versatility is allowing them to become more popular. Installation is fast and straightforward with DIY-friendly click installation systems since the core works well with them. In addition, due to the strength of fiber cores in high-density flooring, the total thickness can often be lowered, facilitating the transition between flooring types.

Advantages Of Engineered Products

It is obvious that engineered wood flooring has natural characteristics since it is made of real wood. But engineered wood flooring has other advantages as well.

  • A higher level of stability is beneficial to older homes that are susceptible to larger heat and humidity changes.
  • A higher level of stability also allows for larger installations.
  • The underlayment of engineered wood flooring can be used to improve insulation and leveling.
  • The choice in Engineered Flooring has increased due to its popularity.
  • The extra stability allows these floors to be installed using click systems.
  • This greatly reduces the risk of cupping.

Engineered flooring can be installed with an adhesive. Engineered flooring is also very versatile. It can be installed in areas with a lot of moisture. There are many different types of engineered flooring. The most common types of engineered flooring are laminate, vinyl plank, and parquet. Engineered flooring is available in a variety of thicknesses. Most types of engineered flooring are offered in 1/4-inch, 3/16 inch, and 1/2 inch thick.

Is A Parallelogram A Rectangle–Or Does a Rectangle Form a Parallelogram?

0

The rectangle and the parallelogram are both quadrilaterals, which means that they are both polygons with four sides. The question is, do rectangles count as parallelograms? On the other hand, are parallelograms regarded as rectangles? Here is a quick review of the different properties of both parallelograms and rectangles to help you understand them better.

The parallelogram is a quadrilateral that has:

·         Two pairs of parallel sides

·         Two pairs of opposite sides that are coincident

A rectangle is a quadrilateral that has:

·         Four right angles

·         Two different pairs of opposite sides

Rhombuses are quadrilaterals that have:

·         Four sides of equal length

·         Two pairs of equal opposite angles

is a rectangle always a parallelogram
is a rectangle always a parallelogram

Properties of a Rectangle vs. a Parallelogram

There are four right angles in a rectangle. These angles are all congruent with one another. In the rectangle, the vertices join the adjacent sides at a 90° angle, indicating that the opposite sides are parallel lines. A rectangle has all of the properties of a parallelogram since it has two series of parallel sides and two sets of opposite sides that are both congruent. For this reason, a rectangle is always a parallelogram.

It is important to note, however, that not all parallelograms are rectangles. An example of a parallelogram that does not have four right angles can be seen below. In the next section, we will discuss these shapes properties.

Properties of a Rectangle vs. a Rhombus

We defined a rhombus above, which is the shape pictured above. In view of the similarity between a rhombus and a rectangle, let’s talk about the similarities between the two shapes.

Besides, a rectangle may not always be a rhombus. There are two sets of congruent sides on a rectangle whereas there are four congruent sides on a rhombus.

Can I ask if rhombuses are always parallelograms? Yes, they are always parallelograms! It is true that the two pairs of opposite angles of a rhombus are always equal, just as the two pairs of opposite angles of a parallelogram are always equal. In other words, a rhombus is just a special case of a parallelogram that happens to also have congruent angles on all four sides.

Is a Rectangle a Parallelogram?

All quadrilaterals have a certain property, whether they are rectangles, parallelograms, or rhombuses.

A parallelogram is a quadrilateral that has:

·         Two pairs of parallel sides

·         Two opposite pairs of sides that are congruent

A rectangle is a quadrilateral that has:

·         Four right angles

·         Two pairs of opposite sides that are congruent

The characteristics of a rhombus are:

·         Four sides of equal length

·         Two pairs of equal opposite angles

In addition to the types of quadrilaterals we have described here, there are many other types of quadrilaterals. As a result, you now know the answer to the question “Is a rectangle a parallelogram?”.” A rectangle is always a parallelogram. It is not necessarily the case that a parallelogram is always a rectangle.

Is WhatsApp Safe – Here’s Everything You Need to Know About the Privacy & Policy

0

It launched in 2009 and was acquired by Facebook in 2014. Recently, WhatsApp has been gaining popularity for its encryption features, which make its chats more secure than others.

WhatsApp states on its website, “From day one, we built WhatsApp to enable you to stay in touch with friends, share essential information during natural disasters, reconnect with separated families, or seek a better life.” WhatsApp allows you to share some of your most personal moments, which is why we built it with end-to-end encryption. Having your communications end-to-end encrypted will prevent your messages, photos, videos, voice messages, documents, and calls from falling into the wrong hands.”

What is the actual security of your communications?

Read on to learn what WhatsApp actually is, if it’s safe, private, and secure, and if you should be worried that your WhatsApp information could get hacked.

WhatsApp: What Is It?

This free messaging app and voice-over-IP service are also known as WhatsApp Messenger. It was launched in 2009 as a free messaging service for international communication. After being acquired by Facebook in 2014, it became more popular among businesses and private entities rather than just international conversations. The platform is used by about 1.5 billion people worldwide.

WhatsApp lets users send and receive totally encrypted text messages, voice messages, voice, and video calls, as well as share locations, documents, images, and other messages with the added safety measure of end-to-end encryption.

It means that, unlike most other apps, like Snapchat for example, which definitely keeps a record of all your selfies somewhere in the Cloud, WhatsApp does not store any of the messages sent on its own servers. However, at the moment the messages sent can be viewed only by the person who sent them and the person(s) they were sent to.

Only the sender and the recipient of a message can see the contents of end-to-end encryption. In addition, this applies to all calls, messages, and files exchanged on the app.

Is WhatsApp Safe?

WhatsApp has earned a reputation as safe, secure, and private due to its end-to-end encryption feature. Does that hold true?

WhatsApp is inherently safer than other messaging apps since it uses end-to-end encryption. You can use Facebook Messenger, Instagram Messages, Snapchat, and even regular iMessage. However, it isn’t foolproof either…

It is important to remember that WhatsApp still asks for your contacts when you set up an account, even if your files and messages are encrypted. However, despite its encryption measures, your personal information is still at risk. Sure, it is lower than most, but it is still at risk.

WhatsApp also tracks the amount of time you spend on the app. WhatsApp still aggregates certain information about how you use the app, even though your files are encrypted. What gives? I guess all apps do that.

Is WhatsApp Private?

WhatsApp is filled with features that make it private – the end-to-end encryption means that messages and file exchanges are private between the sender and the receiver. Other than one exception, WhatsApp does not store any messages on it servers.

Messages that have not been delivered. Since WhatsApp uses WiFi to send messages, sending any message – including an international one – is free since it relies on an internet connection, not a cellular connection. However, if a message fails to send (for whatever reason), it will be stored on WhatsApp’s server… but only until it is delivered.

The service also offers privacy settings that can be customized. It also includes customizing your profile’s visibility so others can see if you are active or not. However, WhatsApp is owned by Facebook. The app tracks how often you use it (and for how long), and it shares this information with Facebook.

Does this information remain private? No. No app is truly private.

Lines Of Symmetry – How to Explain Symmetrical Shapes to Children

0

As part of our series on math’s we will focus on answering the question “What is a line of symmetry? And what is its significance and what are its purposes?” as well as giving you all the information you need to help your child understand this small section of the math’s curriculum! Make sure you scroll all the way to the bottom of the blog so that you can find some practice questions for your child to test their skills.

For example, if you cut an apple into two equal halves, then that apple piece is said to be in symmetry with the one next to it. The second example that I would like to give is that if we cut an equilateral triangle into two equal halves, then the two triangles that form after the intersection are right-angled triangles. For line symmetry there are a few more examples, such as square, rectangle, circle, which can also be considered.

Throughout this blog, we will be providing information and resources designed to help parents, teachers, and caregivers to support home learning and find resources to support home learning during the Covid-19 epidemic and beyond.

Introduction of Line of Symmetry

The line of symmetry is an imaginary line that exactly cuts a shape in half.  This means that if you fold the shape along the line, both halves of the shape would match up exactly. In the same way, it would not change the shape if you decided to place a mirror along the line.

There are four lines of symmetry in a square, as shown in the following illustration.

The symmetry of an equilateral triangle consists of three lines.

Symmetry Lines in Different Symmetrical Shapes

We will be teaching your child about the different shapes and their respective lines of symmetry, but for now, let’s look at some of the most common shapes.

what are lines of symmetry

Learning About Symmetry in Primary School

A teacher might ask the child to draw lines of symmetry on the following shapes provided to him or her in Year 2 as an introduction to symmetry. The most common way to make it easier for children to be clear is to give them a cutout shape which they can fold in half so that they can see clearly that both sides of the shape are the same:

Children are asked in Year 4 to identify lines of symmetry in two-dimensional shapes that have been presented in different orientations. The students will need to be aware that shapes can have more than one symmetry line. It may be asked of the students to examine these regular shapes and consider how many lines of symmetry they can find in them. In this instance, it is helpful for them to cut out the shapes and fold them in half, then look at how many folds have been made.

You may also ask the students to classify shapes according to various properties, such as line symmetry. It is possible to give the students a collection of shapes and ask them to place them into a Carroll diagram in the following manner:

The children in the fifth grade begin to reflect shapes in a mirror line. It may be necessary for students to complete the shading in a shape after reflecting it in a mirror line, or for them to draw half of a shape after reflecting it with a mirror line. The shape is usually provided on squared paper in order to allow the students to complete the shape accurately.

Reflected shapes in a mirror line

There will also be an exercise where the children will be given a quarter of a shape and will then be asked to reflect it in two mirror lines, such as:

As an alternative, they can be shown a shape with shaded squares reflected from two mirror lines, and asked to complete the shading of the squares.
