Microsoft Silverlight Microsoft Silverlight is a web browser plugin that provides support for rich internet applications such as animation, vector graphics and audio-video playback. Silverlight competes with products such as Adobe Flash, Adobe Flex, Flex , Adobe Shockwave, JavaFX, and Apple QuickTime. Now in betatesting, version 2.0 brings improved interactivity and support for .NET languages and development tools. Silverlight was developed under the codename Windows Presentation Foundation/Everywhere (WPF/E). It is compatible with multiple web browser products used on Microsoft Windows and Mac OS X operating systems. Mobile devices, starting with Windows Mobile 6 and Symbian (Series 60) phones, will also be supported. A third-party free software implementation named Moonlight is under development to bring compatible functionality to GNU/Linux.Silverlight provides a retained mode graphics system, similar to WPF and integrates multimedia, graphics, animations and interactivity into a single runtime. It is being designed to work in concert with XAML and is scriptable with JavaScript. XAML can be used for marking up the vector graphics and animations. Textual content created with Silverlight would be more searchable and indexable than that created with Flash as it is not compiled, but represented as text (XAML). Silverlight can also be used to create Windows Sidebar gadgets for Windows Vista. Silverlight supports playback of WMV, WMA and MP3 media content across all supported browsers without requiring Windows Media Player, the Windows Media Player ActiveX control or Windows Media browser plugins. Because Windows Media Video 9 is an implementation of the SMPTE VC-1 standard, Silverlight also supports VC-1 video, though still only in an ASF file format. Furthermore, the Software license agreement says VC-1 is only licensed for the "personal and non-commercial use of a consumer". Silverlight does not support playback of H.264 video. Silverlight makes it possible to dynamically load XML content that can be manipulated through a DOM interface, a technique that is consistent with conventional Ajax techniques. Silverlight exposes a Downloader object which can be used to download content, like scripts, media assets or other data, as may be required by the application application.. With version 2.0, the programming logic can be written in any .NET language, including some common dynamic programming languages like Ruby and Python. A Silverlight application being edited in Microsoft Visual Studio.Silverlight applications can be written in any .NET programming language. As such, any development tools which can be used with .NET languages can work with Silverlight, provided they can target the Silverlight CoreCLR for hosting the application, instead of the .NET Framework CLR. Microsoft has positioned Microsoft Expression Blend versions 2.0 and 2.5 for designing the UI of
Silverlight 1.0 and 2 applications respectively. Visual Studio 2008 can be used to develop and debug Silverlight applications. To create Silverlight projects and let the compiler target CoreCLR, Visual Studio 2008 requires the Silverlight Tools for Visual Studio which is available as a beta release
Hyper LAN Recently, demand for high-speed Internet access is rapidly increasing and a lot of people enjoy broadband wired Internet access services using ADSL ( Asymmetric Digital Subscriber Line) or cable modems at home. On the other hand , the cellular phone is getting very popular and users enjoy its location-free and wire-free services. The cellular phone also enables people to connect their laptop computers to the Internet in location-free and wire-free manners. However ,present cellular systems like GSM (Global System for Mobile communications) can provide much lower data rates compared with those provided by the wired access systems, over a few Mbps(Mega bit per second).Even in the next generation cellular system, UMTS ( Universal Mobile Telecommunications System), the maximum data rate of its initial service is limited up to 384 kbps; therefore even UMTS cannot satisfy users’ expectation of high-speed wireless Internet access. Hence, recently, Mobile Broadband System (MBS) is getting popular and important and wireless LAN (Local Area Network) such as ETSI (European Telecommunication Standardization Institute) standard HIPERLAN (High PErformance Radio Local Area Network) type2 (denoted as H/2) is regarded as a key towards providing high speed wireless access in MBS. H/2 aims at providing high speed multimedia services, security of services , handover when roaming between local and wide area as well as between corporate and public networks. It also aims at providing increased throughput of datacom as well as video streaming applications. It operates in the 5 GHz band with a 100 MHz spectrum. WLAN is W-ATM based and is designed to extend the services of fixed ATM networks to mobile users. H/2 is connection oriented with a connection duration of 2 ms or multiples of that. Connections over the air are time-division multiplexed . H/2 allows interconnection into virtually any type of fixed network technology and can carry Ethernet frames, ATM cells and IP packets. Follows dynamic frequency allocation. Offers bit rates of 54 Mbps.
Body Area Network (BAN)
A Body Area Network is formally defined by IEEE 802.15 as, "a communication standard optimized for low power devices and operation on, in or around the human body (but not limited to humans) to serve a variety of applications including medical, consumer electronics / personal entertainment and other" [IEEE 802.15]. In more common terms, a Body Area Network is a system of devices in close proximity to a persons body that cooperate for the benefit of the user. This paper discusses several uses of the BAN technology As IEEE mentioned, the most obvious application of a BAN is in the medical sector, however there are also more recreational uses to BANs. This paper will discuss the technologies surrounding BANs, as well as several common applications for BANs. At the end of the paper we will briefly discuss the challenges associated with BANs and some solutions that are on the horizon. BAN technology is still an emerging technology, and as such it has a very short history. BAN technology emerges as the natural byproduct of existing sensor network technology and biomedical engineering. Professor Guang-Zhong Yang was the first person to formally define the phrase "Body Sensor Network" (BSN) with publication of his book Body Sensor Networks in 2006. BSN technology represents the lower bound of power and bandwidth from the BAN use case scenarios. However, BAN technology is quite flexible and there are many potential uses for BAN technology in addition to BSNs.
Intel MMX Technology
The Intel MMX™ technology comprises a set of instructions to the Intel architecture (IA) that are designed to greatly enhance the performance of advanced media and communications applications. These extensions (which include new registers, data types and instructions) are combined with the Single Instruction, Multiple Data (SIMD) Execution model to accelerate the performance of applications such as motion video, combined graphics with video, image processing, audio synthesis, speech synthesis and compression, 2D and 3D graphics, which typically use compute-intensive algorithms to accomplish the purpose. All existing soft wares that don’t make use of this technology will also run on the processor without modification. Presented below is an elementary treatise on this technology in a programmer’s point of view. The MMX™ register set consists of eight 64-bit registers . The MMX™ instructions access the MMX™ registers directly using the register names MM0 through MM7. These registers can only be used to perform calculations on the MMX™ data types; they can never be used to address memory. Addressing of MMX™ instruction operands in memory are handled by using the standard IA addressing modes (immediate, register mode etc.) and the general purpose registers.
Transparent Electronics Post under Electronics, Instrumentation at Friday, January 21, 2011 Posted by Anoop M S Transparent electronics is an emerging science and technology field focused on producing ‘invisible’ electronic circuitry and opto-electronic devices. Applications include consumer electronics, new energy sources, and transportation; for example, automobile windshields could transmit visual information to the driver. Glass in almost any setting could also double as an electronic device, possibly improving security systems or offering transparent displays. In a similar vein, windows could be used to produce electrical power. Other civilian and military applications in this research field include realtime wearable displays. As for conventional Si/III–V-based electronics, the basic device structure is based on semiconductor junctions and transistors. However, the device building block materials, the semiconductor, the electric contacts, and the dielectric/passivation layers, must now be transparent in the visible –a true challenge! Therefore, the first scientific goal of this technology must be to discover, understand, and implement transparent high-performance electronic materials. The second goal is their implementation and evaluation in transistor
and circuit structures. The third goal relates to achieving application-specific properties since transistor performance and materials property requirements vary, depending on the final product device specifications. Consequently, to enable this revolutionary technology requires bringing together expertise from various pure and applied sciences, including materials science, chemistry, physics, electrical/electronic/circuit engineering, and display science.
