Any machine that can forever without any extra energy given to it, is a perpetual motion machine obviously such machines requires energy to get than moving, but non thereafter. Every inventor, designer and scientist dreams of making such a machine which has the potential of solving most of the energy problems of this world. But the fact remains that it is impossible to develop such a machine. Because at some point of their working they violate either the first or the second law of thermodynamics. Still many hopeful inventors over a period of ti ....etc

Describe the worlds first Trans-Pacific and Trans-Atlantic realtime switching and streaming transmission of uncompressed 4K motion pictures. This demonstration, of an advanced networked media application, conveyed the 23rd Kyoto Prize events, held on Nov. 10 and 11, 2007, from Kyoto, Japan to Stockholm, Sweden in real-time with life-like image quality. Multiple live 4Kstreams from different cameras were switched over the network into a single uncompressed stream at the directorâ„¢s request, and transmitted to Stockholm via 10 G bit Ethernet ....etc

ABSTRACT
This paper presents methods for moving object detection in airborne video surveillance. The motion segmentation in the above scenario is usually difficult because of small size of the object, motion of camera, and inconsistency in detected object shape etc. Here w ....etc

Human Motion Regeneration using Sensors
Human motion analysis is receiving increasing attention from computer vision researchers. This interest is motivated by a wide spectrum of applications, such as athletic performance analysis, surveillance, man-machine interface, content-based image storage and retrieval, and video conferencing. Three major areas related to interpreting human motion are motion analysis involving human body parts, tracking of human motion using single or multiple cameras, and recognizing human activities from image sequen ....etc

The ultrasonic detector is a popular device for detecting motion in a free space. it is not as versatile as the passive infra-red type mainly due to its restricted range, usually only about 9 meters max. It can be used in situations and environments which mould be unsuitable for the infra-red type as it is not affected by temperature chances.The human ear can hear sounds of frequencies between 20Hz and 20KHz (20,000Hz). Sound waves do exist above 20KHz but me cannot hear them, these very high sounds are called ultrasounds or ultrasonics. Imagin ....etc
