Bluetooth

Bluetooth is an industrial requirement for wireless personal area networks (PANs). Bluetooth provides a way to connect and swap information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are licensed and developed by the Bluetooth Special Interest Group.

Bluetooth is a radio standard and communications protocol mostly designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. The devices use a radio communications system, so they do not have to be in line of view of each other, and can even be in other rooms, as long as the conservative transmission is powerful enough.

Aberrations

A lens is a device for either concentrating or diverging light, usually produced from a piece of shaped glass. Lenses do not form perfect images, and there is always some degree of distortion or aberration introduced by the lens which causes the image to be an defective replica of the object. Careful design of the lens system for a exacting application ensures that the aberration is minimized. There are several different types of aberration which can influence image quality.

Automobile

An automobile (also motor car or simply car) is a wheeled traveler vehicle that carries its own motor. Most definitions of the term specify that automobiles are designed to run mostly on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.However, the term is far from precise.

The economics of personal automobile ownership go away from the initial cost of the vehicle and includes repairs, maintenance, fuel, depreciation, the cost of borrowing, parking fees, tire replacement, taxes and insurance.The capability for humans to travel rapidly from place to place has far reaching implications for the nature of our society. People can now live faraway from their workplaces, the design of our cities is determined as much by the need to get vehicles into and out of the city as the nature of the buildings and public spaces within the city.
