ABS (Anti-Lock Brake System)

 ABS (Anti-Lock Brake System)




ABS helps the driver maintain steering control while braking hard. Wheel-speed sensors designed to detect wheel lockup can send a signal to a control unit that in turn can modulate the brake-line pressure to that wheel.

An anti-lock brake system, ABS, is a system which is designed to prevent you from “locking” up your brakes, or applying so much pressure to your brakes that the axle and your wheels themselves stop turning completely. When your wheels stop turning but your car is still moving too fast, you start to skid, and skidding causes you to lose total control over your vehicle, which is a dangerous prospect when traveling at high speeds.an anti-lock brake system doesn’t actually stop your car faster than a traditional brake system—in fact, it adds a small amount of distance. However, it does enable you to have control over your car, providing you the ability to possibly steer out of the way of an accident and avoid serious injury. Likewise, it increases the lifespan of your tires, your brake pads, your brake calipers, your wheels, and just about everything else on your car which braking can influence.

Traction control is a system designed to keep all four wheels on the ground rolling smoothly. If it detects that one wheel starts to spin irregularly, it will cut off power from your engine until it establishes stable traction again. This is designed to prevent you from skidding out of control by accidentally applying too much power. However, because both your ABS and traction control share a control module and self-diagnostic system, one can sometimes interfere with another. Sometimes an issue with your traction control light can cause your ABS light to come on as well, but other times the issue is with your ABS system. You’ll need to have your vehicle professionally diagnosed to figure out exactly what’s going on.


The anti-lock braking system (ABS) is now a standard safety system in all cars. Its purpose is to keep the driver safe by preventing the wheels from locking when you use the brakes. You are able to keep control over the steering and your vehicle won’t skid as a result of the wheels locking up.

There is a warning light on the dashboard which will come on if there is any problem with the ABS. This is a light that needs to be taken seriously because it is an early warning sign that your ABS needs to be inspected.

There is also a brake system light that will come on if there is an issue with the braking system. It lets you know that it is time to take your vehicle to our specialists to check over your car’s brakes and make any adjustments needed.



TWO THINGS TO KNOW ABOUT ABS SAFETY - 

1) On most vehicles the ABS system does a self-test every time you turn on the car. Once you start your vehicle, the light will briefly come on, and if the computer finds a problem, the light will stay on. If you notice the light flash immediately after starting the vehicle, then it's just a self-check.

2) The brake pedal will act differently when ABS is engaged. That pulsating you notice isn't caused by the adrenaline that you feel in a dangerous situation. It's the ABS system trying to make sure you the mechanical system does not lock up. Once you feel this pulsating, don't release the brake. That would be a signal to the brakes that the danger is over. Instead keep your foot on the brake pedal and let the ABS system do its work.


The sensor is located on the car's transmission and this is why it is sometimes called the transmission speed sensor. It sends information to your speedometer and your engine’s computer to tell the transmission when to shift.

What is 5G technology ?

Compared to 4G, 5G networks offer not only higher download speeds, with a peak speed of 10 gigabits per second but also substantially lower latency, enabling near-instantaneous communication through cellular base stations and antennae. There is one global unified 5G standard: 5G New Radio (5G NR) which has been developed by the 3rd Generation Partnership Project based on specifications defined by the International Telecommunication Union under the IMT-2020 requirements.

The demand for internet access, combined with the emergence of new technologies such as artificial intelligence, the Interne



t of Things (IoT), and automation, is driving a massive increase in the amount of data created. Data creation is growing exponentially, with volumes set to increase by several hundred zettabytes over the coming decade. The current mobile infrastructure was not designed for such a high information load and requires upgrading. 


At the same time, with its high speed, massive capacity, and low latency, 5G could help to support and scale several applications like cloud-connected traffic control, drone delivery, video chatting, and console-quality gaming on the go. From global payments and emergency response to distance education and mobile workforc, the benefits and applications of 5G are limitless. It has the potential to transform the world of work, the global economy, and people's lives.

fully autonomous cars have not been considered viable because of the length of time it takes for a vehicle to send and receive information. However, the low latency of 5G means we could see self-driving cars become more commonplace, with roads connected with transmitters and sensors that send and receive information to vehicles in 1/1,000 of a second. The reduced time is critical for AI and radar technology to interpret what they see (other cars, pedestrians, stop signs) and control the car accordingly. 


In telecommunications, 5G is the "fifth generation" of cellular network technology, as the successor to the fourth generation (4G), and has been deployed by mobile operators worldwide since 2019.


5G networks are cellular networks,[5] in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell communicate by radio waves with a cellular base station via fixed antennas, over frequencies assigned by the base station. The base stations, termed nodes, are connected to switching centers in the telephone network and routers for Internet access by high-bandwidth optical fiber or wireless back haul connections. As in other cellular networks, a mobile device moving from one cell to another is automatically handed off seamlessly.


The industry consortium setting standards for 5G, the 3rd Generation Partnership Project, defines "5G" as any system using 5G NR software—a definition that came into general use by late 2018. 5G continues to use OFDM encoding.


Several network operators use millimeter waves or mm Wave called FR2 in 5G terminology, for additional capacity and higher through puts. Millimeter waves have a shorter range than the lower frequency microwaves, therefore the cells are of a smaller size. Millimeter waves also have more trouble passing through building walls and humans. Millimeter-wave antennas are smaller than the large antennas used in previous cellular networks. The increased data rate is achieved partly by using additional higher-frequency radio waves in addition to the low- and medium-band frequencies used in previous cellular networks. For providing a wide range of services, 5G networks can operate in three frequency bands—low, medium or high.

Technology

Technology is the sum of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems (e.g. machines) applying technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems.

The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.

Technology has many effects. It has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products known as pollution and deplete natural resources to the detriment of Earth's environment. Innovations have always influenced the values of a society and raised new questions in the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics.

Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition.
