To select the best suited IC for charging Li-Ion Battery it’s necessary to take into account and analyze several factors, for example realized product dimensions, USB compatibility and cost of production. This article tells how to make the optimal choice.
Tyco Electronics’ Industrial Type USB Connectors. Solutions for Rigorous Service Industry type applications quite often make requests for connections enhanced stability, mechanical strength and immunity. USB connectors are not exclusion. World leader producer of various connectors TE Connectivity (Tyco Electronics) delivers USB connectors for standard applications, as well as for rigorous service: with enhanced IP20 class mechanical strength and immunity with class IP65-67bayonet connection.
Frequency Synthesizers PLL Systems. Decreasing Noise and Ghost Signals Methods Phase locked loop (PLL) systems are widely used in many applications particularly in frequency synthesizers. Multicounter PLLs may considerably reduce phase noise level at small and high carrier detuning al well as parasitic components level. With correct circuit design and simulation methods PLL systems can provide characteristics necessary for applications with high requirements.
Testing Medicine Systems. LeCroy’s Solutions Up-to-date medicine systems such as innards visual diagnostic systems (for example magnetic resonance imaging system), monitoring ECG systems and many more become more and more complex. To develop and test medicine systems precise and multifunction devices are necessary. Such equipment offers LeCroy.
SimOne General circuit simulation. High Speed, High Precision Electronic circuits simulation is an essential part of electronic systems development process. SPICE algorithms that are commonly used for electronic circuits design are precise but their speed is low when designing large dimension circuits. Company Eremeks program SimOne permits electronic circuits simulation both with classic SPICE algorithms and original programming technologies and up-to-date numerical methods that severely increase computation speed while maintaining simulation high precision.
Certain Global Electronics Development Trends. Russian Industry Outlook The article considers analysis of the global electronics development principle directions on the basis of International Roadmaps composed by world organizations that provide data support for electronic producers

Speed capability of smectic liquid crystals (SLC) with ferroelectric properties is given. Potential unique characteristics and SLC displays application are studied.
Futaba OLED Displays – Flexible and Transparent OLED displays (Organic Light-Emitting Diodes) emerged at the information display market not long ago. Nevertheless they are found in auto industry, measurement equipment, consumer systems and many other systems. This article considers OLED diplays from one of their leading suppliers – Futaba.
Display Week at the Society for Information Displays (SID). Celebrating 50 Years! Author’s impressions of his visit to SID’s display weekю
Evolution of Display Systems Characteristics. Mission Control Centre Methods Main objective of spacecraft mission Information and reference provision systems is various data arrays necessary for making decisions organization for all specialists that take part in spacecraft control. A critical part plays the information display system efficiency that is estimated by a criteria set that numerically determine system degree of conformity to its objectives. The article considers display systems characteristics numerical estimation methods that where developed by Mission Control Centre to provide relevant information.
VCO or YIG? Selection Problem in the Process of Developing High Quality Synthesizer with PLL The key element of each frequency synthesizer with PLL is a VCO or a YIG generator. Achievement in designs on the VCO basis comparable with YIG generators phase noise levels is not a trivial task and to solve it you must have new structures and up-to date technologies, as well as skill to overcome various “secondary” difficulties.
LEDs bright Future. Exhibition and Conference Lightfair International. At the international exhibition and conference Lightfair International 2012 (LFI) devoted to this year innovations in lighting technologies there were generally introduced LED modules and lamps. Will the lighting industry continues to squash LEDs into existing lightings constructions or their unordinary characteristics will inspire new more smart devices? This article conceders exhibition and conference answers to these questions.
Organic LEDs. New Materials, New Technologies In spite of OLED technology evident success there are still many unsolved problems that more or less disrupt its fast and wide range commercialization. Today companies and research centers are extensively searching for more stable and more cheaper organic materials, are solving the problem of long-life performance or the neccessary brightness durability of organic materials used in displays, TV screens, lightning and solar cells.
