Wavelength Selective Switch (WSS) is an optical networking device that dynamically routes, adds, drops, or redirects specific wavelengths in fiber-optic communication networks without converting optical signals into electrical signals.

Smart bras are an emerging category of wearable technology that combines traditional undergarments with advanced sensors and connected features. These garments are designed to monitor various physiological indicators such as heart rate, breathing patterns, body temperature, posture, and physical activity. By integrating electronic components into comfortable fabrics, smart bras provide users with real-time data that can be accessed through mobile applications or connected devices.

The growing interest in health monitoring and fitness tracking has contributed to the development of smart bras across different applications. In sports and fitness, they help users track workout intensity and performance metrics without the need for additional wearable devices. Some advanced models are also being explored for healthcare purposes, including monitoring cardiovascular health and detecting changes in body conditions.

Drone Light Shows are a modern form of aerial entertainment that use coordinated fleets of illuminated drones to create dynamic patterns, animations, and visual storytelling in the night sky. These shows have rapidly gained popularity as a sustainable and technologically advanced alternative to traditional fireworks displays, offering precise choreography, lower noise, and reduced environmental impact.
