Ruvi
The Sony Ruvi is an analog video and still video camera released in 1998. The Ruvi was considerably smaller than any other camcorder available at the time, at 124 mm × 66 mm × 44.1 mm and 380 g. This made the Ruvi small enough to keep inside a shirt pocket. ''Ruvi'' is an abbreviation of ''Recording Unit by Video''. The small size was achieved by making the tape essentially non-removable. A miniature "video cartridge" contained thirty minutes of Hi8 tape permanently loaded around a conventional helical scan record head. The head itself was part of the cartridge, negating the need for a loading mechanism. Although user-replaceable, the cartridge was intended to be a service part and not a form of removable media. The Ruvi contained several features that were considered innovative at the time of its release. The camera had high-density electronics packaging and a color-reflective LCD screen. The Ruvi also featured mechanical linkages for zoom optics. It could record up to 350 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Camcorder
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens. The earliest camcorders were tape-based, recording analog signals onto videotape cassettes. In 2006, digital recording became the norm, with tape replaced by storage media such as mini-HD, microDVD, internal flash memory and SD cards. More recent devices capable of recording video are camera phones and digital cameras primarily intended for still pictures, whereas dedicated camcorders are often equipped with more functions and interfaces than more common cameras, such as an internal optical zoom lens that is able to operate silently with no throttled speed, whereas cameras with protracting zoom lenses commonly thro ...

Still Video Camera
A still video camera (SVC) is a type of electronic camera that takes still images and stores them as single frames of video. They peaked in popularity in the late 1980s and can be seen as the predecessor to the digital camera. However, unlike the latter, the image storage in such cameras is based on analog technology, rather than as a digital file. Design The most common design has an image sensor and basic processing hardware similar to that of a consumer camcorder designed for analog television using the appropriate regional format (NTSC, PAL, or SECAM). However, instead of storing consecutive interlaced fields on tape to form a moving image, a single field or frame (combined from two fields) is extracted from the output video signal and saved on a rotating magnetic disk, typically a standard Video Floppy. During playback, the disk is spun at the frame rate of the video system with the field or frame being read repeatedly. This produces a conventional analog video signal that can ...

Helical Scan
Helical scan is a method of recording high-frequency signals on magnetic tape. It is used in open-reel video tape recorders, video cassette recorders, digital audio tape recorders, and some computer tape drives. History Earl E Masterson from RCA patented the first helical scan method in 1950 after stealing it from German engineer Eduard Schüller. Eduard Schüller developed an actually working helical scan method of recording in 1953 while working at AEG. With the advent of television broadcasting in Japan in the early 1950s, they saw the need for magnetic television signal recording. Dr. Kenichi Sawazaki developed a prototype helical scan recorder in 1954.

Removable Media
Expandable storage is a form of computer storage that is designed to be inserted and removed from a system. Some forms of removable media, such as optical discs, require a reader to be installed in the computer, while others, such as USB flash drives, have all the hardware required to read them built into the device, so only need a driver to be installed in order to communicate with the device. Using removable media poses some risks, including data theft and the introduction of malware. Examples of media that require a reader include: * Optical discs (Blu-rays, DVDs, CDs) * Memory cards (CompactFlash, Secure Digital, Memory Stick) * Floppy and Zip disks * Disk packs * Magnetic tapes * Paper data storage (punched cards, punched tapes) Some removable media readers and drives are integrated into computers, others are themselves removable. Removable media may also refer to some removable storage devices, when they are used to transport or store data. Examples include: * USB flash ...

Still Video Cameras
A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale. Stills have been used to produce perfume and medicine, water for injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol. Application Since ethanol boils at a much lower temperature than water, simple distillation can separate ethanol from water by applying heat to the mixture. Historically, a copper vessel was used for this purpose, since copper removes undesirable sulfur-based compounds from the alcohol. However, many modern stills are made of stainless steel pipes with copper linings to prevent erosion of the entire vessel and lower copper levels in the waste product (which in large distilleries is processed to become animal feed). Copper is the preferred materi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
