| Abstract | This research is focused on the development of a window protection system to prevent pollution of a glass, mirror, or camera lens. For this, a new method for efficient pollution prevention was designed and the characteristic evaluation for developing the system was partly performed.Formerly, the method of using an air purge was generally used for preventing pollution of a camera window. However, the conventional method often induces contaminations due to back flow of air purging. These pollutants can do crucial damage to the camera window and peripheral materials especially in clean room condition. And the conventional method always requires an air supply; therefore, it is difficult to apply the method where an air source cannot be supplied such as a traveling crane located at mountain altitudes. Moreover, the frequent air purging operation or maintenance-personnel intervention causes window surface damage.To solve the above-mentioned problem, an efficient concept for preventing such pollution is proposed in this research. Without air purging, we proposed a new method using repulsion induced by electrifying dirt or moisture to positive magnetic force with high-voltage charge and then injecting gas to the ITO (Indium Tin Oxide) coated window for generating positive ion. In support of the superiority of the designed method for pollution prevention of a window, key factors for permeability and photographing test were defined and partly evaluated as compared with the conventional method.To sum up, in this research, we aim to develop an efficient pollution preventing system for a camera window based on a new method through characteristic evaluation and stabilization of the designed system. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
