Document Cameras
Document cameras, also known as visual presenters, visualizers, digital overheads, or docucams, are real-time image capture devices for displaying an object to a large audience. Like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, in essence, high resolution web cams, mounted on arms so as to facilitate their placement over a page. This allows a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches. Theoretically, all objects can be displayed by a document camera. Most objects are simply placed under the camera. The camera takes the picture which in turn produces a live picture using a projector or monitor. Different types of document camera/visualizer allow great flexibility in terms of placement of objects. Larger objects, for example, can simply be placed in front of the camera and the camera ...

Blended Learning
Blended learning, also known as technology-mediated instruction, web-enhanced instruction, or mixed-mode instruction, is an approach to education that combines online educational materials and opportunities for interaction online with physical place-based classroom methods. Blended learning requires the physical presence of both teacher and student, with some elements of student control over time, place, path, or pace.Friesen, Norm (2012).تیتبصتبخهثبتخهسثتبخسثبخهسثتبسثبخØ"Report:Defining Blended Learning"/ref> While students still attend brick-and-mortar schools with a teacher present, face-to-face classroom practices are combined with computer-mediated activities regarding content and delivery. It is also used in professional development and training settings. Since blended learning is highly context-dependent, a universal conception of it is difficult. Some reports have claimed that a lack of consensus on a hard definition of blended learning ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio-visual
Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions. Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. Components Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of these components are faulty or missing, the system may not demonstrate optimal performance. Wiring is a skill that not only requires proper cable rating selection based on a number of factors, including distance to the main rack, frequency and fire codes, but wires should also be out of sight, behind the walls and in the ceiling, when possible.

Carl Zeiss AG
Carl Zeiss AG (), branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) he laid the foundation for today's multi-national company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue (Industrial Quality and Research, Medical Technology, Consumer Markets and Semiconductor Manufacturing Technology) in almost 50 countries, has 30 production sites and around 25 development sites worldwide.

Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsurgery
Microsurgery is a general term for surgery requiring an operating microscope. The most obvious developments have been procedures developed to allow anastomosis of successively smaller blood vessels and nerves (typically 1 mm in diameter) which have allowed transfer of tissue from one part of the body to another and re-attachment of severed parts. Microsurgical techniques are utilized by several specialties today, such as general surgery, ophthalmology, orthopedic surgery, gynecological surgery, otolaryngology, neurosurgery, oral and maxillofacial surgery, plastic surgery, podiatric surgery and pediatric surgery. History Otolaryngologists were the first physicians to use microsurgical techniques. A Swedish otolaryngologist, Carl-Olof Siggesson Nylén (1892–1978), was the father of microsurgery. In 1921, in the University of Stockholm, he built the first surgical microscope, a modified monocular Brinell-Leitz microscope. At first he used it for operations in animals. In Nove ...

Photokina 1988
Photokina (rendered in the promoters' branding as "photokina") is a trade fair held in Europe for the photographic and imaging industries. It is the world's largest such trade fair. The first Photokina was held in Cologne, Germany, in 1950, and since 1966 it has been held biennially in September at the Koelnmesse Trade Fair and Exhibition Centre in Deutz. The final Photokina under the then-current biennial cycle took place in 2018. Initially, the promoters planned to start a new annual cycle in 2019, with future shows to be held in May, but they later decided not to begin the new annual cycle until 2020. The worldwide outbreak of the Coronavirus disease 2019 and its effect on the imaging industry made Koelnmesse decide to cancel both Photokina 2020 and Photokina 2021. Many photographic and imaging companies introduce and showcase state of the art imaging products at Photokina. Similar trade shows The show has two main competitors, both of which are annual shows held in differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecture Recording
Lecture recording refers to the process of recording and archiving the content of a lecture, conference, or seminar. It consists of hardware and software components that work in synergy to record audio and visual components of the lecture. It is widely used in universities and higher education in the UK and Australia to provide support for students. 71% of institutions replying to a UCISA survey in 2016 indicated that this technology was available in their institution. Where lecture recording is done at scale the recording system may be integrated with the timetabling system and the collection of metadata may be automated. Hardware Hardware is used to capture the lecturer's voice along with the video of the lecturer. Sometimes, the lecturer may use visual aids to support their speech, such as slide shows, which are presented to the audience with some kind of projector. In this case, such slide shows can also be recorded. Once captured, the data is then either stored directly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
