This paper puts forward a new design idea of single lens according to the principle of optical triangulation. The minitype laser triangle probe is designed on the basis of the common direct laser triangulation whose light path is improved. A beam splitter lens is introduced to the path,and the focusing lens and imaging lens are into one. The beam splitter lens, detector and focusing lens are co...
The scaling laws associated with the miniaturization of planar inductively coupled plasmas (ICPs) are investigated. The applications for miniature ICPs include microelectromechanical systems (MEMS) for chemical analysis. Langmuir probe and microwave interferometry measurements of three ICPs with coil diameters of 5, 10, and 15 mm show that electron density typically falls in the range of 10 10 ...
MINIATURIZATION OF THE FREON COMPRESSOR: THE BELLOWS PUMP James L. Kamm University of Toledo Thermal Engineering Company Toledo, Ohio All indicators point to the decade of the 1980's as the years of conservation. Whatever the technological "fix" of the future that will bring endless and sufficient energy supplies, if one exists, it will not be available within this time framework. Conservation ...
One of the undesired effects of software evolution is the proliferation of unused components, or components unlikely to be used by a given subset of the applications. As a consequence, the size of binaries and libraries tends to grow. One of the major trends of today’s software market is the porting of applications on hand-held devices or, in general, on devices having a limited amount of resou...
he future of miniaturization of wireless networks is described from the viewpoint of today’s trends in miniaturization, such as microelectromechanical systems and nanotechnology, along with the move away from computer processing–centric systems to distributed networks. The complexity, convergence of technologies, and connectivity of the remote wireless sensor known as the “mote” are discussed i...
Filter is very essential component in wireless communication system. Since need of compact devices is increasing day by day, Filter plays very important role in developments of such devices. In this paper, multiband micro strip stepped impedance resonator band pass filters operating in range of 1 to 10 GHz are designed. A series capacitively coupled series micro strip line resonator is modified...
Extensive studies of vertebrates have shown that brain size scales to body size following power law functions. Most animals are substantially smaller than vertebrates, and extremely small animals face significant challenges relating to nervous system design and function, yet little is known about their brain allometry. Within a well-defined monophyletic taxon, Formicidae (ants), we analyzed how...
In this paper a novel structure of metamaterial is proposed in order to miniaturize a rectangular microstrip patch antenna. The metamaterial is composed of two nested split octagons which are located on a 10 mmx10 mm Rogers RT/duroid 5880 with 0.7874 mm thickness and dielectric constant of 2.2. A 3X5 array of such metamaterials is placed on the patch antenna substrate. By using this metamateria...
