Active rectification converts AC to DC with low distortion at low voltages. It is used for circuits handling low levels of AC, such as AM sensing. Synchronous rectification is used in alternators. Active devices like transistors and op amps can be used for active rectification. H-bridge can be used for full-wave rectification and bi-directional drive. […]
Active suspension is a computer-controlled system that adjusts the firmness of a vehicle’s ride through computer-activated shocks. It uses magnetic fluid material and traction sensors to detect changes in road conditions and improve handling. The first fully active suspension system was introduced in the early 1990s. Some cars have preset active suspension systems with different […]
Australia has no active volcanoes due to its lack of plate boundaries. Although evidence suggests it had active volcanoes in the past, it has since drifted away. The closest active volcanoes are in Papua New Guinea, Indonesia, the Philippines, and New Zealand. The last recorded eruption in Australia was 5,000 years ago. Mauna Kea in […]
Mercedes-Benz introduced the Active Body Control (ABC) system in 1999, which continuously monitors and corrects the car’s positioning to prevent rolling or losing control. It has three main components: sensors, a microprocessor, and hydraulic servomechanisms. The success of the ABC system led to its integration into other Mercedes-Benz vehicle classes. Since 1978, Mercedes-Benz, a German […]
Mercedes-Benz developed the Active Body Control (ABC) system for over 20 years before introducing it in their CL class vehicles in 1999. The system uses sensors, a microprocessor, and hydraulic servomechanisms to correct the car’s positioning and prevent rolling or loss of control. It has since been integrated into other Mercedes-Benz vehicle classes. Since 1978, […]
Active packaging protects goods during packaging and sale, preserving freshness and providing information. It is used for all products, including pharmaceuticals and food, and extends to bulk shipments. It complies with regulations and benefits both producer and consumer. Sometimes referred to as smart packaging or smart packaging, active packaging is an approach to developing packaging […]
Active exercise requires a person to exert force to complete a movement, while passive exercise involves another person moving the patient’s limbs. Most exercises in gyms are active, while physical therapy involves both simple and assisted active exercises to build muscle and improve cardiovascular performance. The goal is to get muscles to remember how they […]
Active recovery involves low-intensity exercise after high-intensity training to aid in restoring the body to a resting state, minimizing soreness, and increasing stamina and strength. It also has positive effects on mood and cognitive ability. In exercise, active recovery is the process of using low-intensity exercise as a cool-down after some form of training. One […]
An active monitor is a computer on a token ring LAN that supervises and maintains the network by watching other computers, generating empty token frames, and setting a clock to keep all computers in sync. It is crucial for the network’s functioning and is elected through a process of election. An active monitor, in computer […]
Active yogurt cultures aid digestion and may have other health benefits. They are added to pasteurized milk to ferment it into yogurt, with the most common bacteria being Streptococcus thermophilus and Lactobacillus bulgaricus. Look for the National Yogurt Association seal to ensure live cultures, and frozen yogurt needs 10 million cultures per gram. Yogurt products […]
Staying active benefits people of all ages, improving physical fitness, mental alertness, and overall well-being. Exercise can prevent diseases such as Alzheimer’s, heart disease, and cancer. Even activities that stimulate the brain, like reading and socializing, can benefit health. A brisk half-hour walk five times a week can provide health benefits and be easily incorporated […]
ActiveMovie was a streaming media technology for Windows® that allowed users to access streaming video directly from Internet Explorer®. It was replaced by DirectShow® and included in the Microsoft® DirectX® collection of programs. The primary format used was ASF, which held information for retrieving audio and video information. ActiveMovie is a type of streaming media […]
Active vacations combine physical activity with tourism, allowing visitors to interact with new environments. They can focus on one sport or include a variety of activities, and appeal to a wide range of people. Commercial travel makes it easier to participate, with programs designed for novices and families. The phrase “active vacation” can be broadly […]
Active Directory is a Microsoft software technology that provides centralized management of computer networks and security. It uses LDAP for directory structure, Kerberos for authentication, and DNS for IP addresses. Objects are divided into resources and security principles, and the system is organized into forests, trees, and domains with organizational units for distributed management. Information […]
Active travel involves using the human body as a transportation machine, such as walking or cycling. It is commonly used for commuting and can have health and environmental benefits. However, the layout of urban and rural areas can make it difficult. Active travel can also refer to vacations that involve energetic activities. Active travel is […]
Active Desktop was a feature in older versions of Windows and Internet Explorer that allowed HTML content to be displayed on the desktop. It was disliked by users and has been dropped in newer versions. It played a role in the Microsoft antitrust lawsuit. Newer versions have similar features with better integration. Active Desktop® is […]
Active stretching involves contracting the agonist muscle to relax the antagonist muscle and increase flexibility. It is recommended as a progression to passive stretching, which can activate the muscle spindle reflex. Similar methods include PNF and resistance stretching. Active stretching is an exercise technique intended to increase flexibility in a muscle by activating a reflex […]
Maintaining an active lifestyle doesn’t have to be expensive or complicated. Regular exercise, modifying habits, and incorporating physical activity into leisure time or volunteering can all help. Walking for 90-150 minutes a week is a simple and cheap way to stay healthy, and leisure activities like dancing or walking the dog can also be beneficial. […]
Active matrix technology is used in laptops and notebooks for high-quality, low-power displays. It uses thin film transistors to create a more precise and dynamic image compared to passive matrix displays. The term was coined in 1975 by Dr. Peter Brody. Active matrix is a technology used in flat panel liquid crystal displays in notebooks […]
Active objects are a design pattern used in computer programming to ensure that a service is always available in a multi-threaded system. They allow for input processing without blocking concurrent processes and are wrapped in a publicly accessible interface called a proxy. This creates a design pattern where objects send messages to active objects and […]
