    Temperature Sensor for Housed Electronics

    Temperature Sensors

    Even in programmable options, temperature sensors are of a great benefit to anyone who has a 120 mm fan kit and wants to only run it when necessary to save on electricity. This is a great “green” addition to any setup. Many wonder how IC temperature sensors compare to other types; to include RTD, thermocouples and more.

    The best feature of them is the ease of integration with any 120 mm fan kit as well as the many other size fans that are provided by distributors. In addition, they are the low cost solution. Any limitations are not a concern when it comes to electronic system protection applications. This is because they have a smaller temperature range.

    Simple Sensors for Simple Systems

    These sensors can make it easy for anyone to add protective elements to any system. Temperature once the 120mm fan is install depends on many things. Among them are air flow, thermal resistance, ambient temperature and output power. Fans reduce amp temperature but there is always the issue of noise.

    That’s why installing a sensor is smart. It makes the 120 mm fan kit only run when the temperature is that high that forced-air cooling is required. In turn, this minimizes noise output. The result of a well-designed system is reduced noise, and in most cases the fan won’t even be needed unless the components are being overused. When mounting the sensor, the best spot is on the other side of the circuit board, or away from the heat sink.

    The sensor should be mounted in a place that provides good correlation with die temperature. If the heat sink is mounted against one side of the printed circuit board, mounting the sensor on the other side of the circuit board works well. IC1 consists of a temperature sensor, a 1.25 V voltage about, and a dual comparator.

    Finding the Right Products

    There are many suppliers that give both the 120 mm fan kit, mounting supplies, filters, temperature sensors, cords and everything one needs to build the perfect setup at home. Often times, they come at deep discounts when ordered in bulk. However, if they are needed singly that is welcome too.

    Further, the experts that run these supply stores that are found in brick and mortar locations as well as online are usually happy to help anyone to choose what they need. No one should be hesitant to delve in and start building the perfect cooling system to protect their components whether in a residential or commercial setting.

    Cloud Backup Solutions

    The biggest problem is that a majority of companies still use old traditional methods. Backing up their systems to external hard drives which they store in an office or safe, not the ideal situation. In the event of a fire or flood, it is possible that not only the computers get damaged, but the safe is compromised, affecting the drives inside, which again means you lose everything.

    Computer disasters are known to cost companies thousands each and every year, which is why you need to be prepared. It doesn’t matter if you have a small work from home office or you run a large corporation, the importance of backing up your system is exactly the same.

    Another problem that is seen with traditional methods of backing up systems is that team members will set an hour aside at the end of each week, backing up their files for the week. While this is diligent, it’s not good enough. In the event of something going wrong with the computer, you will have lost an entire weeks’ worth of work. If all the systems are infected or suffer the same fate, then you lose a weeks’ worth of work off each and every computer in the office. As you can imagine, this is hours of work and possibly thousands of potential income.

    The cloud backup solutions are a leading choice for many companies today who want to ensure that their information and data is safe and secure at all time. This is an affordable solution, which enables you to pay for what you need. For smaller companies you will find that you can use a set amount of storage space online that you need, adding more space as the business grows. It’s a type of modular system, which caters to companies of any size with complete ease.

    The benefit to cloud backup solutions is that you can access the data you have stored at anytime from anywhere. This means that if you get home and realise you forgot to draw up an important invoice or document, you can do it in the comfort of your home at your own personal computer with the log in information you have been provided.

    All you need to use cloud backup storage is an internet connection. This means you can access the data off your phone, tablet or computer at any time. This is very advantageous for managers and directors of companies that want to continue working after hours, but still leave the office.

    Further when you use this type of solution you will find that the backup is stored off site, this reduces the risk of the all your data being destroyed in the event of a fire or other disaster. With the information backed up away from the office, you have complete peace of mind that it will be there when you need it.

    Further you will find that the system is automatic. Not risk of your system not being backed up for days on end. As a document is saved or a report is drawn, the system will automatically back it up to the system, so you know your backup is always current.

    Using BIM Services

    Key characteristics of BIM

    BIM refers to Building Information Modelling, which takes imaging and documentation of buildings to a whole new level. These take into account sophisticated software as well as programs that are not limited to the primitive 2D images that were prevalent in the past. The advantage of using BIM services is that the whole of the building product lifecycle is catered to at the click of a few buttons. You can look at the whole gamut of design of buildings and then storage of the data in a secure manner with options for dynamic change and thereon helping in the production and actuation of the building into reality.

    Intelligent Design

    BIM services are very advantageous to building design and implementation because it considers what are known as intelligent design and storage facilities. In a traditional 2D image, you could do only so much with reference to data storage and modification. But BIM gives a dynamic modelling option wherein you can look at not only the building and its interiors in a dynamic manner, but the whole eco-system of buildings, surroundings and landscape around are integrated in a very savvy manner.

    Marketing attributes

    BIM is also of great use in marketing and advertising of building, especially when it comes to commercial, as well as residential buildings. Consumers are no longer satisfied with a simple brochure that gives a 2D image of the prospective office, retail space or an apartment. They want dynamic and slick computer-based representations of the proposed building that is effective in giving a beautiful image from all angles that are indeed the best advertising proposition that a building marketer could expect.

    Network Time Servers

    Scheduled System Backups

    Maintaining a routine monthly schedule of successful data back ups is critical to every organization. If systems become out of sync, fail to back up correctly, or at all, it can pose as a liability to your organization. Backups are vital for making sure your system and network remains stable and secure from outside attack.

    Accelerate Your Network

    If your organization uses a wide area file system with multiple users contributing to documents, it can be difficult to figure out which version of a document is the most current. A network accelerator is a type of time server that keeps the time synchronized between multiple devices and users so that multiple people can collaborate on a project, even in real time.

    Network Management

    Should something go wrong with your network, the first place to turn to find out what went wrong is the system log. This log is a key piece of troubleshooting and diagnosing problems. However, if these logs are not synchronized, it can take much longer to find the problem and repair system functioning and performance.

    Intrusion Awareness and Analysis

    In the event that someone is able to hack into your network, you will want to know how the network became compromised and what data might have been accessed by the intruder. This is only possible if your router and service logs are accurately time stamped. Usually, hackers will delete these system logs, however, if they do not and your time data is inaccurate, hackers will have more time and opportunities to exploit the network.

    Regulatory Compliance

    Sometimes, regulatory agencies such as HIPAA and GLBA, as well as others, require your data and transactions to be accurately time stamped. This can aid in the transparency of your business operations, and help speed things along in the event of an audit.

    Misconceptions About Church Tech

    1. “The church does not use Technology.”
      One of the greatest uses of technology was the application of the printing press to mass produce copies of the Holy Bible. Johannes Gutenberg, considered the inventor of the printing press. used technology to mass produce books and quickly spread knowledge in 15th century Europe. The Gutenburg Bible is an early use of church tech to spread the gospel.
    2. “Older congregants will not embrace technology.”
      This is a commonly held belief based largely on assumptions. Not only is this not true, but a study by Dunham and Company showed that online giving among those over 65 was equal to that of those younger. Senior Americans have traditionally been late adopters of technology. But according to the Pew Research Center. Seniors are embracing technology at a surprising rate. In 2013, 59% were internet users.
    3. “Technology will be our problem”
      Technology itself is not bad, but it also is not foolproof. It’s all in how it is applied. The problem comes when church tech becomes a substitute for human interaction. People and churches require physical connection and human interaction for survival. Church tech should encourage and enhance, but not replace, the human part of the church experience.
    4. “All technologies are created equal” and
    5. “It doesn’t cost anything.”
      Because of open source technology, an increasing number of tools and apps are available free or at a very low cost.

    VPN Authentication and Encryption

    Something you have – can be a key card, a security pass, drivers licence, a passport or similar. The possession of one of the above items is usually enough to confirm the identity of the holder. The problem with this is that the device can be lost or stolen, and sometimes used by other persons.

    Something you know – a password, pass phrase or some other known information that can be used to calculate function from a secret message.

    Something you are – A physical characteristic of your body such as your finger print, the retina print of your eye or your DNA.

    Encryption is a means of taking some plain readable text into a cipher text utilizing some form of algorithmic mapping. The intended receiver of such a cipher text must have the means to reverse the process by knowing the same algorithm, but an attacker cannot know the process.

    Encryption systems must use mathematically complex algorithms so as to provide a good enough deterrent from attackers to be able to use some brute force method of calculating the algorithm in use. Two common methods of encryption are Symmetric Encryption Systems and Public Key Encryption Systems:

    Symmetric encryption simply uses an identical key for encryption of the plain text and decryption of the cipher text. and decryption at both ends. The encryptor applies the key to the plain text data which results in a cipher text. The decryptor reverses the by applying the same key to the cipher text to reveal the plain text data. The most common symmetric encryption system is the Data Encryption Standard (DES), of which there are several variations.

    Public Key Encryption systems are a lot more complex than symmetric encryption systems such as DES and depend upon mathematical functions that are often referred to as “trap-door” functions. They involve complex mathematical formulae which normally involve exponentiation to high powers, modular arithmetic and the products of large prime numbers. The algorithms yield an encryption mechanism and an encryption key which can be made public and a decryption algorithm and decryption key that is kept secret. The mathematics of the algorithms is so complex that it is not possible to deduce the decryption mechanism from the encryption mechanism alone.

    Digital Signatures

    To construct a Digital Signature, public key encryption systems must be in place. The construction of the Digital Signature entails applying a hash function to the message by concatenation of the message with a known secret key and then applying a mathematical function which will produce a fixed length output known as the digest. The digest is then encrypted with the public decryption key which produces a signature that can be appended to the message to verify that the message is from the genuine source.

    The receiver recalculates the hash function and compared with the signature after applying the public key. If the two match, then because only the originator could have known the hash function and the private key, the message must be genuine.

    Message Digest algorithms use Hash functions to map many potential inputs to each of a large number of outputs. What is normally produced is a fixed length field, typically a few hundred bits in length. A secret key is shared between sender and receiver and by concatenating this with a message for transfer, the digest is produced.

    MD5 (Message Digest 5) is probably the most common hash function used, and it produces a 128 bit digest which is often appended to the header before the packet is transmitted. Any change in the message will cause the digest to change, and even the source and destination IP addresses can be used together with the message contents when creating the digest, which validates the addresses.

    Another popular hashing algorithm is SHA (Secure Hash Algorithm) that produces a 160 bit digest ensuring greater security than MD5.

    It doesn’t matter how long the digest is, an identical digest will always result for an identical packet. But anyone wishing to attack the system could monitor exchanges and determine which packets sent in what ever order would result in some known result. This result could therefore be reproduced by replay of the messages. This is known as a collision attack.

    HMAC (Hash-based Message Authentication Code) can be used to combat collision attacks by including two calculated values know as ipid and opid, which are initially calculated using the secret key for the first packet and recalculated for subsequent packets. The values are stored after each packet and recovered for use in the calculation of the digest for the next packet. This ensures that the digest is always different even for identical packets.

    A Digital Certificate is produced using some known information such as name, address, mother’s maiden name, house number, National Insurance number, or indeed anything. This information is appended to the public key and then used as part of the hash function to create the digest which is then encrypted using the private key through a secure encryption system such as RSA or AES.

    A Digital Certificate can be validated by passing it through the public encryption process with the public key for the user to yield the digest. This can be compared with the calculation of the digest from the claimed identity of the user and their public key. If the two calculations yield the same result then the certificate is valid. Digital certificates are appended to messages to verify the authenticity of the source of the message.
