Scooter (motorcycle)

A scooter or motor scooter is a motorcycle with step-through frame and a platform for the rider's feet. Elements of scooter design have been present in some of the earliest motorcycles, and motorcycles identifiable as scooters have been made from 1914 or earlier. Scooter development continued in Europe and the United States between the World Wars.

The global popularity of scooters dates from the post-World War II introductions of the Vespa and the Lambretta. These scooters were intended to provide low-power personal transportation (engines from 50 to 250 cc or 3.1 to 15.3 cu in). The original layout is still widely used in this application. Maxi-scooters, with engines from 250 to 850 cc (15 to 52 cu in) have been developed for Western markets.

Scooters are popular for personal transport, partly due to being cheap to buy, easy to operate and convenient to park and store. Licensing requirements for scooters are easier and cheaper than for cars in most parts of the world, and insurance is usually cheaper.

Diver propulsion vehicle

A diver propulsion vehicle (DPV, also known as an underwater propulsion vehicle or underwater scooter) is an item of diving equipment used by scuba and rebreather divers to increase range underwater. Range is restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed under exertion, and the time limits imposed by the dive tables to avoid decompression sickness. DPVs can have military application.

Structure

A DPV usually consists of a pressure resistant watertight casing containing a battery-powered electric motor, which drives a propeller. The design must ensure that the propeller cannot harm the diver, diving equipment or marine life, the vehicle cannot be accidentally started or run away from the diver, and it remains neutrally buoyant while in use underwater.

Application

DPVs are useful for extending the range of a diver that is otherwise restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed under exertion, diver fatigue, and the time limits imposed by the dive tables to avoid decompression sickness. Typical uses include cave diving and technical diving where the vehicles help move bulky equipment and make better use of the limited underwater time imposed by the decompression requirements of deep diving.

Poing

Poing may refer to:

Poing, Bavaria

Poing is a community in the Upper Bavarian district of Ebersberg, lying 18 kilometres (11 mi) east of central Munich.

Geography

Poing is approximately 20 kilometres (12 mi) NE of Munich and is serviced by the Munich S-Bahn (S2) and MVV Bus systems. Poing has two constituent communities named Angelbrechting and Grub. Poing is bordered on the east by Anzing and Markt Schwaben, Pliening in the North, Kirchheim to the West and Parsdorf to the South.

History

It is believed that Poing has been settled for more than 5,000 years. The ending on the community’s name suggests a Celtic origin.

Population development

Over the last few decades, Poing has developed rapidly from a small village into the second biggest community in the S-Bahn line 2 (S2) area (up to Erding) and into the second biggest community in Ebersberg after Vaterstetten. In 2006, it overtook the once dominant neighboring community of Kirchheim. The sharp rise in population is due to the many new building projects in the northern area of the city, to which no end is yet foreseen. Therefore, even more development projects are expected.

Poing (video game)

Poing is a freeware computer game, made by Paul Van der Valk, and released on the Amiga in 1992. It is a variant of the arcade games Breakout and Arkanoid but is presented in a horizontal orientation similar to the 8 bit computer game Krakout.

Description

Gameplay

The game is divided into stages, each containing a number of levels. Each level consists of a rectangular playing area, which contains an arrangement of blocks. The levels appear in a random order each game. In later versions this feature became optional.

In each level, the player controls a simple paddle, which is positioned on the left side of the playing area and can be moved up or down. The player uses the paddle to deflect strategically a ball, which can damage or destroy blocks on contact.

To complete a level, the right-hand wall of the playing area must be hit by the ball a number of times to break it, and then the ball must pass through the right-hand side, taking it to the next level. A 'Force' bar in the corner of the screen indicates the number of hits required. At the start of each level the wall needs to be hit 10 times, but powerups can damage or recover the wall.
