The electronic cigarette is not new. People who buy electronic cigarette knows that this product has been in the market for years now. Despite some sectors apparently trying to shoot the product down from the shelves, the popularity of elect Active shredder safety technology for the small office. Shreds 15sheets per pass into 5/32" x 1-1/2" cross-cut particles (Security Level3). Patented SafeSense® Technology stops shredding when hands touch thepaper opening. Designated shredde

A visual presenter (also known as document camera) is an information and communication technology presentation for teaching in the classrooms. It can be directly connected with PC or interactive whiteboard, projector or LCD screen. It is one of the most adaptable presentation tools for teaching of today’s times. It can show any kind of material , i.e. photographs, books or 2D-3D objects quickly and also provide high resolution output for videos, projectors, monitors and interactive whiteboards or video-conferencing.There are three types of visual presenter available in the market:Desktop Visual PresenterPortable Visual PresenterGooseneck Visual PresenterThe desktop has a large operating surface area, can be operated without a computer and portable visual presenters are especially useful for the view between teachers and students to be maintained unhindered. The gooseneck visual presenter provides flexibility, which can be attached to a microscope that helps in showing small objects into a larger view.Usage in Arts and CraftsVisual presenter is not restricted to cater a particular subject. Its flexibility enables to use the device for different purposes. Hence, teachers can use this device for their respective subjects. Likewise, in case of arts and crafts classes, if teachers want to make a sculpture of a seashell wind chime while making the wind chime and an instructor wants to drill a tiny hole in each shell. It can be shown to a large number of students with ease, by putting your hands under the camera lens. It will be promptly visible to the students sitting at any corner or place in the classroom. Teachers as well as students enjoy the class session without any interruption.Use for Laboratory materialFor subjects like physics, here, students need to know about various apparatuses in physics lab like a prism, a lens and a mirror. Visual presenters are able to show small parts of apparatus, i.e. vernier caliper, screw gauge. It lets us show the small parts of vernier caliper namely outside jaws, sliding strip and depth probe in giant form on the display screen very easily. It helps the student seeing the image easily without exerting the eyes.Another important apparatus of physics lab is screw gauge which is also known by micrometer. The name itself suggests measuring the small lengths. Teachers do not need to worry about showing the minute details to the students. Having a Visual presenter, helps in displaying the small details at ease. Any microscopic objects, slides and celestial body can also be shown to every student effortlessly by attaching the head of a visual presenter to microscope.For instance, prism, which is a three-dimensional object of solid shape. While discussing the terms of prism with image correctly. Sometimes, students irritate teachers by saying, “Ma’am, we could not understand the concept clearly”. Can you please illustrate one more time? Wait a minute; Teachers have visual presenters that save the lecture with audio-video recording for innumerable queries, can be shown anytime. In the same way, students can be acquainted with the concave and convex mirror with its rules of reflection with focal point diagrams more precisely.Most of the students face problems in ray diagrams; it needs practice for a couple of times. A visual presenter makes it easier to understand quickly and correctly by way of animated representation of ray diagrams for concave or convex mirrors, enable them to imbibe the concepts for a lifetime. It also helps the students for illustrating the same for practical. Similarly, the light rays of the lenses to converge or diverge as they pass can be understood more effectively with the assistance of animated representation through visual presenters. Here, teachers can clear the concepts for a number of times; teachers do not need to draw diagrams again and again, due to the suitability of the recording function.Visual presenters can also be used in biology labs 3-D objects, i.e. flowers, leaves, and specimens. Students can understand the working of the surgical and dissection tools like blades, forceps, scalpels, tissue punches for dissection activities and its storage. Such tools can easily be known by putting the tools under the camera, the image of the tool will clearly be visible to the large number of students. Teachers can easily show the structure related to chemistry lab likewise, atomic bond angles. Visual presenters are also helpful in understanding the angles between the bonds and their molecular structure- linear, trigonal planar, tetrahedral, octahedral and trigonal pyramidal with 3-D representation and bond angles.In order to understand the molecular structure effectively, use a diagrammatic representation of bonds as sticks or lines for 2-D molecular structures through a visual presenter. The space filling models or CPR models which show atoms in color scheme in representations, wherein the molecule is represented by overlapping spheres representing the atoms. If a teacher tries to show it by hands, everyone will not be able to see it clearly. If try by using a visual presenter, can expect good response from the students side. The clear picture will give more clarification among students by converting the hardest session into much more eased-out.Students get hard times, when it comes to understanding mathematics. For better understanding the Pythagoras theorem can be understood by using charts or models. By using visual presenters, teachers can make the whole phobic session into more fun and understandable. Students tend to relate more when they study with the help of diagrams. Actually, it makes the concept more practical that how the mathematical concepts can be applied in an interesting way. Everyone knows when a teacher makes a graph for some mathematical equations, it takes a lot of time, sometimes becomes untidy that students hardly understand it and keep mum while the teacher completes it. Students become hesitant to clear the queries because of improper graph. Ready-made charts or textbook content can be put under the camera lens of visual presenters. It will show the proper image to each and every student in a clear manner. On the whole, everything looks interesting and pragmatic. Seemingly, it is giving meaning to the education system where teachers and students tend to correlate with the concepts by infusing fresh ideas. Visual presenters have the capability to create interest for the students as well as for teachers.
