Window Shutter
A window shutter is a solid and stable window covering usually consisting of a frame of vertical stiles and horizontal rails (top, centre and bottom). Set within this frame can be louvers (both operable or fixed, horizontal or vertical), solid panels, fabric, glass and almost any other item that can be mounted within a frame. Shutters may be employed for a variety of reasons, including controlling the amount of sunlight that enters a room, to provide privacy, security, to protect against weather or unwanted intrusion or damage and to enhance the aesthetics of a building. Depending on the application, and the construction of the window frame, shutters can be mounted to fit within the opening or to overlap the opening. The term window shutter includes both interior shutters, used on the inside of a house or building, and exterior shutters, used on the outside of a structure. On some styles of buildings it is common to have shutters to cover the doors as well as the windows. Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roller Shutter
A roller shutter, security shutter, coiling door, roller door or sectional overhead door is a specialized type of door or window shutter consisting of multiple horizontal slats, bars, or web systems interconnected through hinges. The mechanism involves lifting the door to open it and lowering it to close. In the case of larger doors, an automated, motorized system may be employed. This versatile design offers comprehensive protection against various elements, including wind, rain, fire, and theft. When utilized as a shutter in front of windows, it serves as a formidable deterrent against vandalism and thwarting burglary attempts, reinforcing the security of the enclosed space. Applications Roller shutters have many applications including doors for vans, Garage (house), garages, kitchens, schools, prisons and warehouses. They are also commonly used as window blinds in some European countries, such as Italy, Germany, France and Spain. These shutters serve as insulation in locati ...

Hurricane Shutter
Hurricane coverings, commonly known as shutters, are used in hurricane mitigation to protect houses and other structures from damage caused by storms. Hurricane shutters are used to prevent windows from being broken by flying objects during a storm. Although the negative pressure caused by high-speed wind flowing over a building roof can cause the roof to fail with the building envelope intact, broken windows allow the air pressure to rise inside a building, creating an even greater pressure difference and increasing the likelihood of roof failure. Shutters are frequently constructed from steel or aluminium, but homeowners sometimes use the low-cost alternative of plywood. The shutters are affixed to the outside of the building with screws, hurricane clips, or a track system. Advanced shutters may be motorized, and they may fold away when not in use. Types of hurricane coverings Three major types of shutters are known alternatively as panel systems. They are usually made of pl ...

Shutter (photography)
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp. A shutter of variable speed is used to control exposure time of the film. The shutter is constructed so that it automatically closes after a certain required time interval. The speed of the shutter is controlled either automatically by the camera based on the overall settings of the camera, manually through digital settings, or manually by a ring outside the camera on which various timings are marked. Camera shutter Camera shutters can be fitted in several positions: * Leaf shutters are usually fitted within a lens assembly (''central shutter''), or more rarely immediately behind (''behind-the-lens shutter'') or, even more rarely, in front of a lens, and s ...

Signal Lamp
Signal lamp training during World War II A signal lamp (sometimes called an Aldis lamp or a Morse lamp) is a visual signaling device for optical communication by flashes of a lamp, typically using Morse code. The idea of flashing dots and dashes from a lantern was first put into practice by Captain Philip Howard Colomb, of the Royal Navy, in 1867. Colomb's design used limelight for illumination, and his original code was not the same as Morse code. During World War I, German signalers used optical Morse transmitters called ', with a range of up to 8 km (5 miles) at night, using red filters for undetected communications. Modern signal lamps produce a focused pulse of light, either by opening and closing shutters mounted in front of the lamp, or by tilting a concave mirror. They continue to be used to the present day on naval vessels and for aviation light signals in air traffic control towers, as a backup device in case of a complete failure of an aircraft's radio.

Movie Projector Shutter
A movie projector (or film projector) is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors (see also digital cinema). Many projectors are specific to a particular film gauge and not all movie projectors are film projectors since the use of film is required. Predecessors The main precursor to the movie projector was the magic lantern. In its most common setup it had a concave mirror behind a light source to help direct as much light as possible through a painted glass picture slide and a lens, out of the lantern onto a screen. Simple mechanics to have the painted images moving were probably implemented since Christiaan Huygens introduced the apparatus around 1659. Initially, candles and oil lamps were used, but other light sources, such as the argand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Shutter
A remote camera, also known as a trail camera or game camera, is a camera placed by a photographer in areas where the photographer generally cannot be at the camera to snap the shutter. This includes areas with limited access, tight spaces where a person is not allowed, or just another angle so that the photographer can simultaneously take pictures of the same moment from different locations. Remote cameras are most widely used in sports photography. 35 mm digital or film, and medium format cameras are the most common types of cameras that are used. Uses and practices Remote cameras are used by photographers to take more pictures from different angles. Remotes are very popular in sports and wildlife photography. Cameras are often placed in angles that a photographer cannot physically be during a shoot. Sport use examples include behind the backboard at a basketball game or overhead in the rafters of an arena during a hockey game. Placement Remote cameras placed in sus ...

Bradbury–Nielsen Shutter
A Bradbury–Nielsen shutter (or Bradbury–Nielsen gate) is a type of electrical ion gate, which was first proposed in an article by Norris Bradbury and Russel A. Nielsen, where they used it as an electron filter. Today they are used in the field of mass spectrometry where they are used in both Time-of-flight mass spectrometry, TOF mass spectrometers and in ion mobility spectrometers , as well as Hadamard transform mass spectrometers (a variant of TOF-MS). The Bradbury–Nielsen shutter is ideal for injecting short pulses of ions and can be used to improve the mass resolution of TOF instruments by reducing the initial pulse size as compared to other methods of ion injection. Theory of operation The concept behind the Bradbury–Nielsen shutter is to apply a high frequency voltage in a 180° out-of-phase manner to alternate wires in a grid which is orthogonal to the path of the ion beam. This results in charged particles only passing directly through the shutter at certain times in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
