AP Diving
AP Diving or Ambient Pressure Diving, formerly known as A.P.Valves, is a British manufacturer of diving equipment at Water-Ma-Trout in Helston, Cornwall, England. They produce a range of scuba and surface-supplied diving equipment including buoyancy compensator jackets and the Inspiration range of electronically controlled closed circuit diving rebreathers. The firm started in 1969 making a valve to allow a diver to breathe from a stabiliser jacket buoyancy compensator's inflation cylinder. They progressed to making divers' adjustable buoyancy life-jackets and stabiliser jackets, and then other diving equipment such as rebreathers. and diving accessories etc. They often exhibit at diving trade shows. Product lines *"Inspiration" rebreathers have been in production since 1997. The earliest model, now known as the Inspiration classic, reached the end of its product support life in April 2017 after 20 years.

Underwater Diving Equipment Manufacturers
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ways and often inaccessi ...

Engineering Companies Of The United Kingdom
Engineering is the practice of using natural science, mathematics, and the engineering design process to Problem solving#Engineering, solve problems within technology, increase efficiency and productivity, and improve Systems engineering, systems. Modern engineering comprises many subfields which include designing and improving infrastructure, machinery, vehicles, electronics, Materials engineering, materials, and energy systems. The Academic discipline, discipline of engineering encompasses a broad range of more Academic specialization, specialized fields of engineering, each with a more specific emphasis for applications of applied mathematics, mathematics and applied science, science. See glossary of engineering. The word '':wikt:engineering, engineering'' is derived from the Latin .

Rebreather Makers
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantial unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, while also eliminating the bubbles otherwise produced by an open circuit system. The latter advantage over other systems is useful for covert military operations by frogmen, as well as for undisturbed observation of underwater wildlife. A rebreather is generally understood to be a portable apparatus carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supply ...

European Underwater Federation
The European Underwater Federation (EUF) is an umbrella organisation representing the interests of scuba diver training organisations operating in both the Voluntary sector, not for profit and Business, for profit sectors within Europe. Purpose and scope EUF seeks to be the peak consultative body within Europe in respect to all matters that concern recreational diving activities, particularly those concerning legislation, regulation and safety. By virtue of the knowledge and experience of its corporate members, it claims an area of competency within recreational, cultural and sporting underwater activities in matters such as the conduct of diving activities (including competitive activities), access to diving sites, training, all aspects of diving equipment, treatment of diving injuries, teaching and the use of recreational diving techniques by professional persons. It claims no expertise in areas involving commercial or military diving. Members The EUF has a membership cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backwards Compatible
In telecommunications and computing, backward compatibility (or backwards compatibility) is a property of an operating system, software, real-world product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. Such breaking usually incurs various types of costs, such as switching cost. A complementary concept is ''forward compatibility''; a design that is forward-compatible usually has a roadmap for compatibility with future standards and products. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel represented by one signal. With the introduction of two-channel stereo FM radio, many listeners had only mono FM receivers. Forward compatibility for mono receivers wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving (other), diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have Physiology, physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness ...

Buoyancy Compensator (diving)
Buoyancy (), or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may be also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the displaced fluid. For this reason, an object with average density greater than the surrounding fluid tends to sink because its weight is greater than the weight of the fluid it displaces. If the object is less dense, buo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
