Power management ICs are used to manage power requirements and to support voltage scaling and power delivery sequencing in power electronic devices. They are the key components in any electronic device with a power supply, battery, or power cord and they optimize power usage. The power management ICs that are used in smartphones are referred to as smartphone power management ICs.
Description
Party Balloons are air-tight bags made out of latex a light material or foil that can be inflated with air or other gas. The ordinary air, or other gases such as helium, can be forced into them for expansion purposes. Latex balloons are available in all kinds of shapes, sizes, and colors to delight children and adults at birthday parties and other festive occasions or used as a tool of advertisement.
Description
A hookah is a smoking device with a single or multi-stemmed instrument for vaporizing and smoking flavored tobacco, called shisha, whose vapor or smoke is passed through a water basin—often glass-based—before inhalation. There are two kinds of hookahs: the traditional ones that you see in hookah bars and newer hookah pens (e-hookahs). Health risks of smoking hookah include exposure to toxic chemicals that are not filtered out by the water and risk of infectious disease when hookahs are shared.
Description
Lidar (also called LIDAR, LiDAR, and LADAR) is a surveying method that measures distance to a target by illuminating that target with a pulsed laser light, and measuring the reflected pulses with a sensor. Differences in laser return times and wavelengths can then be used to make digital representations of the target. The name lidar, sometimes considered an acronym of Light Detection And Ranging (sometimes Light Imaging, Detection, And Ranging), was originally a portmanteau of light and radar. 
Lidar is popularly used to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. The technology is also used for control and navigation for some autonomous cars. Lidar sometimes is called laser scanning and 3D scanning, with terrestrial, airborne, and mobile applications.
In this report, we mainly study radar sensors which used in the automotive industry.
