Glucose Meter ... Since approximately 1980, a primary goal of the management of type 1 diabetes and type 2 diabetes mellitus has been achieving closer-to-normal levels of glucose in the blood for as much of the time as possible, guided by HBGM several times a day. The benefits include a reduction in the occurrence rate and severity of long-term complications from hyperglycemia as well as a reduction in the short-term, potentially life-threatening complications of hypoglycemia...

Mobile Phone Features ... The common components found on all phones are: A battery, providing the power source for the phone functions. An input mechanism to allow the user to interact with the phone...

Camera Phone ... Most camera phones are simpler than separate digital cameras. Their usual fixed focus lenses and smaller sensors limit their performance in poor lighting...

History Of Mobile Phones ... Mobile phone history is often divided into generations (first, second, third and so on) to mark significant step changes in capabilities as the technology improved. Pioneers of radio telephony By 1930, telephone customers in the United States could place a call to a passenger on a liner in the Atlantic Ocean...

Telephone Tapping ... In the United States, under the Foreign Intelligence Surveillance Act, federal intelligence agencies can get approval for wiretaps from the United States Foreign Intelligence Surveillance Court, a court with secret proceedings, or in certain circumstances from the Attorney General without a court order. Under United States federal law and most state laws, there is nothing illegal about one of the parties to a telephone call recording the conversation, or giving permission for calls to be recorded or permitting their telephone line to be tapped...

Mobile Phone ... In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones...

3G ... Several telecommunications companies market wireless mobile Internet services as 3G, indicating that the advertised service is provided over a 3G wireless network. Services advertised as 3G are required to meet IMT-2000 technical standards, including standards for reliability and speed (data transfer rates)...

Japanese Literature ... The 10th century Japanese narrative, Taketori Monogatari, can be considered an early example of proto-science fiction. The protagonist of the story, Kaguya-hime, is a princess from the Moon who is sent to Earth for safety during a celestial war, and is found and raised by a bamboo cutter...

Stereoscopy ... Wheatstone originally used his stereoscope (a rather bulky device) with drawings because photography was not yet available, yet his original paper seems to foresee the development of a realistic imaging method:...

View Camera ... The bellows is a flexible, accordion-pleated box, which encloses the space between the lens and film, and has the ability to flex to accommodate the movements of the standards. The front standard is a board at the front of the camera which holds the lens and, usually, a shutter...

Single-lens Reflex Camera ... Prior to the development of SLR, all cameras with viewfinders had two optical light paths: one path through the lens to the film, and another path positioned above (TLR or twin-lens reflex) or to the side (rangefinder). Because the viewfinder and the film lens cannot share the same optical path, the viewing lens is aimed to intersect with the film lens at a fixed point somewhere in front of the camera...

History Of Photography ... The novel Giphantie (by the French Tiphaigne de la Roche, 1729–74) described what can be interpreted as photography... Early History: Development of chemical photography Monochrome process The first permanent photograph was an image produced in 1826 by the French inventor Joseph Nicéphore Niépce...

Film ... It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry. Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them...

Film Format ... Other characteristics usually include the film gauge, pulldown method, lens anamorphosis (or lack thereof), and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ...

Optics ... Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice...

Digital Photography ... Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing...

Photography ... But in an article published on February 25 of the same year in a German newspaper called the Vossische Zeitung, Johann von Maedler, a Berlin astronomer, had used the word photography already... The word photography derives from the Greek φωτός (phōtos), genitive of φῶς (phōs), "light" and γραφή (graphé) "representation by means of lines" or "drawing", together meaning "drawing with light"...

Film Crew ... Crew are distinguished from cast, the actors who appear in front of the camera or provide voices for characters in the film. Crew are also separate from producers, those who own a portion of either the film company or the film's intellectual property rights...

Holography ... The holographic recording itself is not a plain image – it consists of an apparently random structure of either varying intensity, density or profile. Overview and history The Hungarian-British physicist Dennis Gabor (Hungarian name: Gábor Dénes), was awarded the Nobel Prize in Physics in 1971 for "for his invention and development of the holographic method"...

Telephoto Lens ... Telephoto lenses are sometimes broken into the further sub-types of medium telephoto: lenses covering between a 30° and 10° field of view (85mm to 135mm in 35mm film format), and super telephoto: lenses covering between 8° through less than 1° field of view (over 300mm in 35mm film format). Construction If a camera lens were to be constructed from a single lens of 500 mm focal length, then when the lens is focused on an object at infinity, the lens will be 500 mm away from the focal plane where the film or sensor is...

Shutter (photography) ... Other mechanisms than the dilating aperture and the sliding curtains have been used; anything which exposes the film to light (for a specified time) will suffice. The time for which a shutter remains open (exposure time) is determined by a timing mechanism...
