Computer Security

So you’ve gone out and purchased a brand new laptop, and now you have plans of using that laptop in the workplace. Well, for anyone who has experience running a company, knows that laptops can be conduits for spyware and viruses. Once data is being processed, thought must go into who is capable of stealing it, where they might store it, how they could archive it, and how valuable the data is to the company.

Well, if you want to ensure you’re never in any unfortunate positions, then I suggest you check out my list of common mistakes most new computer users make.

 1. Connecting to an Unsecure Network

If the network is open, then it should be fine for you to connect to, right? I wouldn’t say that. You should always be suspicious of open networks, especially ones at hotels and airports. If it’s possible for you to connect to a network without using a password or agreeing to any terms, then there is a good chance you could be leading yourself into a trap.

 2. Opening Attachments from Unsolicited Emails

You want to check the content of your emails, if anything in it looks suspicious, or if the sender is asking you to do something that you do not feel comfortable doing then there is a good chance its spam.

Check the sender, if you’re not familiar with the person, then try searching for the email on any of the major search engines. If you’re at your workplace, then consider contacting your email administrator for verification on whether or not the email is spam.

3. Using Common Passwords

While the vast majority of people are wise enough not to fall into this trap, especially when signing up for services online, there are still many work colleagues that have a knack for using basic passwords, like their birthday or their username123.

You’ll want to re-work your password by combining uppercase letters, numbers and uncommon symbols. If you chose London as your password, then you could rejig it to something like L0nd3N. Even though it isn’t the most complex password, it would be much more difficult for a hacker to guess.

4. Not Making Backups

When it comes to archiving files, many end users make the common mistake of backing up data too infrequently. I can see how the lazy approach can be more comforting, but if your company files are that important to you, then you’ll want to ensure that they are backed up as often as possible, using a number of different mediums, such as the cloud, external hard drives, etc.

 5. Leaving Your Webcam Enabled

It’s a great idea for you to familiarise yourself with your webcam so that you can determine when it’s disabled or active. Hackers are very adept at hacking into your webcam, especially in the workplace, and they can even record meetings if you’re not careful. Covering the webcam with tape won’t do much since audio can still be recorded; it’s for this reason why you’ll want to ensure its disabled when not in use.

6. Searching the Deep Web

The deep web, unfamiliar to most internet users, is the shady part of it, not accessible from the major search engines like Bing and Google.

Work systems should be used for work only, there are many deep websites out there that will stick malicious code onto your computer and use that to track whatever you say and do.

7. Assuming Your Hard Drive Will Never Fail

In this world, there are two different kinds of computer users, those who have lost computer files and those who will eventually lose computer files. You want to back things up as often as you can. You also want to think about alternative media, like using an external hard drive to save certain confidential data onto it.

8. Using a Suspicious Thumb Drive

Everyone needs a place to store their work documents. If you’re in the office, it’s not uncommon for you to find a thumb drive lying around. My advice is not to use it, especially if you don’t know where it came from, that’s because there’s a good chance it could have a virus on it.

9. Using the Same Password across Accounts

It’s very important that you make a habit of changing your passwords. It’s not uncommon for end-users to keep the same password for many years. That is something you do not want to do.

For business-critical, sensitive data, you want to ensure that all passwords are changed at least once every three months.

Make sure all your accounts have different passwords. Having multiple passwords for your many accounts reduces the chances of all your accounts being compromised. With the increasing amount of cyber-attacks, the age of your password, along with its length and complexity are far more important today.

10. Agreeing to Install Anti-Virus Software

Have you ever visited a website that asked you whether or not you wanted to check your system for a virus? You may have asked how or why it knew you needed a virus scan. In most cases these prompts to install antivirus software are in fact attempts to install malicious software on your system.

Safety Valves

Why Use Safety Valves? Introduction to Safety Valves

A safety valve is one of the important mechanical devices used in several industrial applications to protect systems from overpressure. Excess pressure build-up in the system can cause explosions, fires, and damages to critical components and products. Safety valves are designed to stop these problems by reducing or removing excess pressure from the system. They are specially designed to be actuated by the fluid being controlled; hence, it works when pneumatic or electronic safety controls fail. Below, we have covered more about safety valves: types, working principles, applications, selection criteria, and everything in between. Safety Valve Working Principle The general working mechanism of safety is simple. When the pressure of a system exceeds the maximum allowable working pressure (MWAP), safety valves quickly open to remove the excess pressure before it even builds up. These valves are fast-acting, and they open fully until the system pressure comes back to normal. Most safety valves have a smaller inlet port and a larger discharge outlet. This ensures that any overpressure can be quickly corrected without damaging the sensitive machine parts. The detailed working principle of safety valves from opening to closing depends on the design and application of the valve. We've highlighted more on this below. Types of Safety Valves and Use Cases There are three main types of safety valves. These are: Spring-loaded safety valves Pilot-operated safety valves Safety valves with balanced bellows a. Spring-loaded Safety Valves This is one of the most common types where the valve is held closed by a spring, and the balance between the input force and the spring force determines the closing and opening of the valve. Most spring-loaded valves used in everyday applications come with a flat poppet valve, but those designed for specific liquids and gases come with varying valve shapes. Some even come with a lifting chamber that provides more lift, reducing the time it takes to eliminate the excess pressure in a system. Spring-loaded valves for vapor and gases often open before the MWAP is reached, and the valve is lifted at least 50% at the MWAP. The problem with this type is increased backpressure that interferes with the safety of the valve. Backpressure is defined as the pressure that builds upon the outlet of the safety valve as the fluid medium flows out. Most spring-loaded valves are available for pressure ranges between 1 bar and 1400 bar. Figure 2: (A) Expansion chamber, (B) Spring, (C) Disc, (D) Nozzle ring (E) Nozzle. b. Valves with Balanced Bellows This type of safety valve comes with metallic bellows that increase the poppet valve's surface area. The benefit to this is reduced backpressure hence more safe operation. The spring mechanism is also isolated from the fluid media; thus, there's no undesirable influence on the spring force. That said, most valves with balanced bellows are designed to handle backpressure not exceeding 16 bar. c. Pilot-operated Safety Valves A pilot-operated safety valve has its popper valve held onto the nozzle by the inlet pressure, helping avoid leaks or undesired openings. When the inlet pressure is lower than the maximum working pressure, the safety valve will always remain open. However, as soon as the inlet pressure goes beyond the response pressure, the valves open instantly, allowing the media to flow and reducing the pressure. As soon as the pressure comes back to normal, the valve closes. All three types of safety valves find applications in different industrial settings. Some of the common areas where safety valves are used include oil and gas, manufacturing, food processing plants, refineries, pressure booster systems, and more. Choosing a Safety Valve Before picking a safety valve in the flooded market, you should always consider the following: The response pressure or the maximum allowable working pressure. The backpressure at which the valve can operate without causing safety issues. The discharge capacity of the safety valve. The valve's operating temperature. Valve and sealing material. Besides the above factors, you should also check the certifications required for your specific industry. For instance, safety valves used in the oil and gas industry will vary significantly from those used in the beverage and food industry. Some of the common certifications and standards in the market include ASME, TUV, and ISO 4126. Summary A safety valve is an important mechanical device that helps solve the problems associated with overpressure. There are three main types of safety valves: spring-loaded valves, pilot-operated valves, and those with balanced bellows. When the inlet pressure is higher than the maximum allowable working pressure, safety valves open up to avoid pressure build-up. This, in turn, avoids damages, fires, explosions, and injuries. The right choice of safety valve will largely depend on your unique needs. Some of the critical factors to consider are response pressure, operating temperature, seal and valve material, discharge capacity, and backpressure. You may also want to do thorough research before choosing a safety valve from a given manufacturer. For instance, check the manufacturer's reputation, warranty, industry experience, customer reviews, etc. Read Also: The Fishing Industry Needs More Sustainability Awareness 8 Ways you can Improve Safety in a Workplace 7 Things to Do After a Car Accident in Fort Worth For Your Protection and Safety LPG Safety Tips and Precautions for your Home

brushless servo motor

Types of servo motors: The brushless servo motor

Essentially, a brushless servo motor is a machine capable of developing high torques in order to oppose any effort that tries to take it out of synchronism. The name brushless comes from the simple fact that it does not have brushes and this is a way to differentiate it from other types of servomotors. Compared with other types of motors, the inertia of a brushless servo motor is substantially less. Both these characteristics - important overloads and reduced inertias – are appreciated and useful features for movement control because they allow rapid accelerations and decelerations, as well as precise position control at high speeds. The most commonly used brushless servo motors in the industry, are those formed by a segmented stator in which the space filled with copper is almost double that in the traditional ones. This allows developing a greater power within a lower volume. Constructively, the brushless servo motor has a stator with a laminated core and a uniformly distributed three-phase winding. The rotor is constituted by a group of magnets fixed on the axis of the rotation. The shape of the rotors varies according to the design and can be cylindric or with outgoing poles. Due to the high centrifugal forces to which they are submitted during the acceleration process, the fixing of the magnets to the rotor has been one of the critical points in the construction of brushless servo motors. This has been solved by using mechanical fixings of different types glued together using special adhesives. In order to compensate for the greater amount of thread in the slots and its greater generation of heat, the free space of the winding is filled with heat-conducting resin. The rotor incorporates a series of permanent magnets that provide greater flow density and better performance. The positioning time is reduced thanks to the reduction of rotor inertia that allows reaching high speeds in short times. The Main Characteristics of this type of servo motor are: Performance and high torque Reliability of operation Low maintenance Great accuracy in speed and position control Very high-speed capacity Very low rotor losses Rotor with low inertia Closed construction, useful for working in dirty environments Wide range of powers (from 100 w to 300 kW) The main advantages of the brushless servo motor are given by the possibilities that this type of motor offers in the control of its speed and positioning. Moreover, the possibility of construction of brushless servo motors allows the adaptation of the same to diverse industrial applications. The brushless servo motors of compact structure, incorporate within it an encoder absolute which provides information on the status of the process to the controller. Those who work in a vertical position, incorporate a mechanical brake on which blocks the axis in case of lack of tension to avoid possible falls of parts in case of failure. Inside the brushless servo motor is included as an element for the control. The encoder is formed by an electronic circuit, in which a laser diode emits a beam of light, which is interrupted by the grooves of a metal foil, giving rise to a flashing signal. Each signal, through the corresponding connector cable, arrives at the control element for processing.
