International Laser Display Association
The International Laser Display Association (ILDA) is the worldwide non-profit trade association and is dedicated to advancing the use of laser displays in art, entertainment and education. It was founded in August 1986. ILDA sponsors an annual conference and the annual ILDA Awards for artistic and technical achievement in laser shows and displays. While increasing public awareness of laser light shows, the ILDA is also an association that provides a base for laser display companies. The ILDA does not perform laser light shows itself, but its members primarily consist of laser light show hosts or companies that sell equipment and services. Members of the company can work with each other, not as competitors, but as colleagues with whom they can collaborate. Being associated with ILDA, members can have professional backing that will supply information on new technologies regarding safety issues and improved display performance. ILDA History ILDA was founded on August 16, 1986, at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Lighting Display
A laser lighting display or laser light show involves the use of laser light to entertain an audience. A laser light show may consist only of projected laser light beam, beams set to music, or may accompany another form of entertainment, typically musical performances. Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection. This inherently more focused beam is also extremely visible, and is often used as an effect. Sometimes the beams are "bounced" to different positions with mirrors to create laser sculptures. Function Scanning Laser scanners reflect the laser beam on small mirrors which are mounted on galvanometers to which a control voltage is applied. The beam is deflected a ce ...

CDRH
The Center for Devices and Radiological Health (CDRH) is the branch of the United States Food and Drug Administration (FDA) responsible for the premarket approval of all medical devices, as well as overseeing the manufacturing, performance and safety of these devices. The CDRH also oversees the radiation safety performance of non-medical devices which emit certain types of electromagnetic radiation, such as cellular phones and microwave ovens. The current head of the CDRH is Jeffrey Shuren, who took over in January 2010. Regulatory classes CDRH splits medical devices into three classes with different regulatory requirements: Class 1 devices include everyday items such as toothbrushes which are unlikely to cause serious consequences if they fail. Manufacturers are required to follow what are called "general controls" which closely match ISO 9000 requirements. In addition to the general controls, Class 2 devices require a premarket notification. This process, commonly known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DB-25
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems. Description, nomenclature, and variants A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. D-sub connectors have gender: parts with pin contacts are called ''male connectors'' or ''plugs'', while those with socket contacts are called ''female connectors'' or ''sockets''. The socket's shield fits tightly inside the plug's shield. Panel mounted connectors usually have #4-40 UNC (as designated with the Unified Thread Standard) jackscrews that accept screws on the cable end connector cover that are used for locking the connectors together and offering mechanical strain relief, and can ...
