A car security system is a comprehensive network of electronic and mechanical components which are designed to protect a vehicle from unauthorized access, theft, and vandalism. These systems typically include alarm sirens, immobilizers, keyless entry, central locking, motion detectors, and GPS tracking technologies. Car security systems function by detecting suspicious activities such as forced entry or vehicle movement and triggering alerts to deter intruders or notify the vehicle owner. As vehicle theft methods are evolving, modern security systems are being integrated with smart features such as biometric access, smartphone controls, and real-time tracking, making them essential for personal vehicle protection and insurance compliance.

A centrifugal chiller is a high-performance cooling system that removes heat from a liquid using the principle of centrifugal force. This technology works by using an impeller to compress refrigerant vapor, creating a pressure difference that facilitates heat transfer and effective cooling. One of the best features of centrifugal chillers is their efficiency. These systems are known for their ability to deliver large-scale cooling with minimal energy consumption, making them ideal for commercial and industrial settings. There are different types of centrifugal chillers, including air-cooled and water-cooled models, each designed to perform optimally under different environmental conditions and load requirements.

Cementless total knee arthroplasty (TKA), also known as uncemented or press-fit TKA, is a surgical procedure in which the knee joint is replaced with implants that do not require bone cement for fixation. Instead, these implants are designed to encourage natural bone growth, allowing the bone to grow into the implant and secure it in place. This method aims to achieve a more natural and durable bond between the bone and the implant over time.

A bulletproof helmet is a type of protective headgear designed to shield the wearer from ballistic threats such as bullets, shrapnel, and shell fragments. These helmets are primarily used by military personnel, law enforcement officers, and security professionals in high-risk environments. Unlike standard helmets, bulletproof models are constructed with specialized materials that can absorb and disperse the energy from projectile impacts, significantly reducing the risk of fatal head injuries.
