Simple measures avoid common scams on the internet, including against mature people. Learn about actions that provide digital security for seniors.

New technologies are important tools to facilitate the daily lives of the population and it is not for nothing that the Central Bank found, in the Financial Citizenship Report 2021, that “the access of the elderly to the financial system increasingly passes through digital”. In this scenario, the dissemination of measures to ensure digital security for the elderly becomes even more relevant.

According to the same Central Bank document, the increase in digital solutions available by financial institutions has also reached the longest-lived. The covid-19 pandemic ended up intensifying this reach, “both due to the need caused by social distancing (…) and the launch of solutions, such as Pix, which reduced the technological barrier faced with more intensity by this part of the population”.

However, the popularization of digital solutions also reveals the challenges of people 60+ who tend to have more difficulty with learning new tools.

But it is important to know that with some measures it is possible to improve digital security and avoid the main scams on the internet, in order to generate the true inclusion of mature people in the new digital financial products.

After all, what is digital security?

Digital security is, in simple terms, the adoption of rules and procedures with a single purpose: to protect users from vulnerabilities in systems and networks from possible cyber crimes.

Such infractions revolve around the search for improper access to personal, financial and other confidential data , whether for theft, obtaining an unlawful advantage in credit negotiations or even to threaten users with extortion and other actions.

The great challenge of digital security is directly related to the popularization of the internet and the massive use of the network. Currently, there are millions of connected devices and the preparation of criminals is increasingly elaborate.

Therefore, in view of the digitization of society, in general, digital security is essential for safe access for all.

How important is digital security for seniors?

Through the internet, using a cell phone, tablet or computer, it is possible to perform a series of services, which makes the routine more comfortable and safe.

Retirees and pensioners, for example, have access to managed security services in the palm of their hands , without having to go to a physical branch for service. Therefore, they can track payments, request services and much more, thanks to platforms like Meu INSS and SouGov .

On the other hand, the growing evolution of digital users also incurs risks for virtual security, mainly due to the lack of recognition of the importance of the proper use of the internet for digital security.

There are several criminal practices that can result in the theft of personal data, financial information, as well as values in bank accounts and even taking undue loans on behalf of third parties. Given this, it is crucial to understand that digital security is indispensable, especially for the 60+ population.

Therefore, although there is an enormous ease in the routine of these people, thanks to the use of the internet, it is vital to observe certain practices to protect personal information and property.

7 precautions to avoid digital scams

Recent data from the Central Bank also showed that, in line with the rest of the population, the elderly also began to use mobile devices (such as cell phones and tablets) more and less to access the internet in recent years.

However, regardless of the medium used, following some general tips are essential with regard to digital security for the elderly. Below are 7 tips for using the internet safely.

1. Beware of personal data

The sharing of personal information on the internet should be avoided, being restricted to trusted sites and platforms that offer digital security requirements . This is because this type of carelessness can facilitate scam applications, such as hacking into social media accounts, identity theft, signing loan agreements, etc.

This kind of care also applies when it comes to buying online. To avoid having data accessed improperly, it is important to check the security attributes of the pages, which must have the “HTTPS” security seal.

In addition, it is also necessary to analyze the connection, given that public networks and computers or smartphones with viruses are subject to invasions. Thus, any data entered using a public internet network can be easily intercepted.

2. Password creation and management

The password is nothing more than a code to access digital accounts, whether banking or shopping sites and social networks. However, when it comes to financial services, care is even greater with them, given that malicious people can access victims’ balances remotely, if the password has fallen into the wrong hands.

In order not to generate greater opportunities for this type of crime, it is very important to choose passwords correctly. Therefore, dates of birth, telephone numbers or identification documents, as well as sequential letters and numbers , should be avoided as a password .

In addition, using password managers can make life even easier for users on the internet: this type of tool gathers all passwords in one space, including access codes for social networks, banks, credit cards, among others. In this way, managers function as “safes” that keep access information to different platforms safe, without the need to memorize all of them.

The security of managers is linked to the encryption system; through the manager itself, it is enough for the user to memorize the so-called “master password”.

3. Double authentication on digital platforms

Dual authentication or two-factor authentication, as it is also known, is another useful digital security feature for seniors. The procedure makes it difficult to access accounts improperly, even if the password has been leaked, for example.

Basically, this system consists of sending a PIN code for login authorization, either by email or SMS, on registered devices. In general, lost, stolen or hacked cell phones tend to be more fragile if this feature is disabled. Consequently, third parties may have access to profiles on social networks, as well as bank accounts.

On the other hand, by keeping the information of the second factor enabled , it will be possible to inhibit access to any type of information or personal data. It is worth noting that among the most common mechanisms, 2FA stands out. Through it, the interested party informs his access password and the service sends an SMS or e-mail containing the code for user authentication.

4. Use biometrics

Another way of digital protection is using the biometric system. Like double authentication, this procedure consists of a mechanism that allows access to a specific application or digital platform through biometric recognition of both the fingerprint and the face or vocal timbre.

This is a very secure and sophisticated method , since its characteristics prevent unauthorized access, as it is less exposed to possible vulnerabilities — after all, each individual has unique biometric information. Therefore, this system is considered very efficient.

5. Do not open links from strangers

A very common criminal practice is known as phishing or phishing scam and is associated with the main forms of fraudulent access to email accounts, financial applications and profiles on social networks. This type of scam consists of sending false messages both via email and social networks (mainly WhatsApp).

This scam is characterized by sending messages containing “baits” to draw the user’s attention and make him perform some action, even if it puts him at risk. When attracted by the criminal through these messages, the victim usually informs sensitive data such as bank accounts, passwords and other confidential information.

6. Do not transfer money without checking first

Payment and money transfer has become a very common practice, even more so with the institution of Pix , an instant and no-cost payment method created by the Central Bank in 2020.

Through the internet it is possible to pay slips and make electronic transfers between accounts with a few clicks. In the case of bank slips, this type of payment is more used by those who do not have a bank account or even do not have a credit card.

7. Use only secure networks

Finally, another fundamental point in digital security for the elderly is the use of internet networks. Many establishments offer free Wi-Fi to consumers.

However, what few people know is that this type of public network is not secure, especially for carrying out financial transactions , as well as accessing sensitive data — such as passwords for social networks, bank accounts and credit cards.

Thus, it is necessary to perform such actions using a secure internet connection. If not possible, an alternative is to use the mobile data of the cell phone. In addition, using computers that are shared by many people, such as library or work PCs, to access sensitive information is not recommended.

Generative AI, instead of copying or recognising predefined patterns based upon rules, uses complex algorithms based often on neural networks to create original content.

These developments have been made possible by the huge advances in machine learning, a branch of AI which involves teaching computers how to learn using data. Data collection, model-training, learning from data, examining model output, and adjusting parameters are all part of this process. The development of neural networks, a type of computational training model inspired by the brain, has been made possible through machine learning. These models are built from interconnected virtual “neurons” that are organized into “layers” to process data. This system allows a model to be taught how to balance different parameters in order to recognise patterns and learn them, as well as make predictions and complete tasks. Deep learning is another name for this subset of machine-learning.

Deep learning focuses on training artificial neural networks with multiple layers to represent complex data. The term ‘deep’ refers to the depth of the neural network, meaning the many layers of inputs or outputs. This system has been highly successful in solving tasks like image recognition (recognising images/faces/patterns), natural language processing (ChatGPT-like models which can understand and generate human-like responses, most often used to power chatbots) and speech recognition (used for voice assistants or transcribing speech to text) among others.

BLDC Motor Controller Design Principles

Published

7 months ago

April 25, 2024

sylvia J

BLDC (Brushless DC) motors are widely used in various applications, from consumer electronics and appliances to automotive and industrial systems. To control the speed and direction of BLDC motors, specialized motor controllers are required. At Integra Sources, we specialize in designing custom BLDC motor controllers that meet the unique requirements of our clients’ applications.

What Is a BLDC Motor Controller?

A BLDC motor controller is an electronic device that controls the speed, direction, and torque of a BLDC motor. It consists of a microcontroller or digital signal processor (DSP) that generates the control signals for the motor’s power electronics, including the power transistors or MOSFETs. The BLDC motor controller also includes feedback sensors, such as Hall effect sensors or encoders, to provide feedback on the motor’s speed and position.

Key Design Principles of BLDC Motor Controllers

Sensorless vs. Sensored Control: BLDC motor controllers can be classified into two main types: sensorless and sensored control. Sensorless control relies on the back electromotive force (EMF) of the motor to determine its speed and position, while sensored control uses external sensors, such as Hall effect sensors or encoders, to provide feedback. The choice between sensorless and sensored control depends on factors such as cost, complexity, and performance requirements.
Commutation Techniques: BLDC motors require electronic commutation to control the timing of the motor’s winding currents. There are several commutation techniques used in BLDC motor controllers, including trapezoidal (six-step) commutation and sinusoidal (vector) commutation. Trapezoidal commutation is simpler and more cost-effective but may result in lower efficiency and torque ripple. Sinusoidal commutation provides smoother and more efficient motor operation but requires more complex control algorithms and hardware.
Control Algorithms: The control algorithm used in a BLDC motor controller determines how the motor’s speed and torque are regulated. Common control algorithms include open-loop control, closed-loop speed control, and closed-loop position control. Open-loop control provides basic speed regulation but does not account for variations in load or motor parameters. Closed-loop control algorithms use feedback from sensors to adjust the motor’s speed and position in real time, providing precise control over the motor’s operation.
PWM (Pulse-Width Modulation) Techniques: PWM is used to control the average voltage applied to the motor windings, thereby controlling bldc motors. There are several PWM techniques used in BLDC motor controllers, including six-step commutation PWM, sinusoidal PWM, and space vector modulation (SVM). These techniques vary in complexity and efficiency, with space vector modulation offering the highest level of control and efficiency.
Overcurrent and Overtemperature Protection: BLDC motor controllers must include protection features to prevent damage to the motor and controller in the event of faults or overloads. Overcurrent protection limits the motor’s current to prevent overheating and damage to the motor windings. Overtemperature protection monitors the temperature of the motor and controller and reduces the motor’s power if it exceeds a safe threshold.
