LONDON — Samsung Electronics Co., Ltd., plans to start sampling soon a CMOS image sensor (CIS) with 5 megapixel QSXGA resolution. Volume production of the device, targeted at mobile phones, digital cameras and camcorders, is expected to commence by the end of the year.

MANHASSET, N.Y. &#151 Artesyn Communication Products and Wind River Systems Inc. have joined forces to offer the Wind River platform for network equipment, running on Linux, for Artesyn's AdvancedTCA telecom blade servers.

Artesyn (Madison, Wi.) and Wind River (Alameda, Calif.) will work together to develop carrier-grade Linux and VxWorks board support packages (BSP) for Artesyn's telecom blades, beginning with the PowerPC processor-based KatanaQp AdvancedTCA blade. Wind River will provide validation services for the new BSPs.Both companies will work together to market the new products.Wind River Platform for Network Equipment, available with the latest mainstream releases of OSDL Carrier Grade Linux (version 2.0.1) and the Linux 2.6.10 kernel, combines Wind River's Eclipse-based Workbench development suite with a rich set of networking middleware. The platform makes it easy for telecom device developers to develop and deploy a complete range of network equipment applications, from core and enterprise to access and edge devices.Wind River is a pre-eminent supplier of real-time operating systems and has taken the lead in offering an integrated development and run-time environment for carrier-grade Linux,” said Todd Wynia, vice president of marketing at Artesyn, in a statement. Our high-availability AdvancedTCA blades, together with Wind River Platform for Network Equipment, provide an ideal foundation for building a broad range of high-availability telecom infrastructure systems.”

LONDON — Speaking at the annual meeting of the European Venture Capital Association (EVCA) here, Herman Daems, the outgoing EVCA chairman, called on the European Union to rewrite tax laws to make it easier for venture capitalists to invest across country borders, according to reports.

Daems said changes in international regulation could make Europe as competitive as the U.S., the reports said.

Separately, the EVCA outlined seven principles of good governance, including transparency, integrity and confidentiality.

At the end of the conference Sir David Cooksey, chairman of U.K. based venture capital company, Advent Venture Partners and founding chairman of the British Venture Capital Association, was elected as EVCA chairman for the period June 2005 to June 2006.

SAN JOSE, Calif. &#151 Worldwide polysilicon material shortages are worse than previously expected &#151 a development that could cause silicon wafer prices to increase by up to 5 percent in 2006, warned an analyst on Thursday (June 23).

And a possible increase in silicon wafer prices could also impact the global supply chain, causing prices for semiconductors to increase by one-half of 1 percent” in 2006, said Paul Leming, an analyst with Princeton Tech Research (Princeton Junction, N.J.).

As reported in May, prices for polysilicon jumped by about 25 percent, with product shortages expected to last until 2006 or 2007. The troubling supply trends for these materials could hamper the overall growth rates in the semiconductor and solar cell industries, according to analysts.

Första generationen Boeing utvecklade jumbojeten 747 1968. Konstruktionen var revolutionerande i fråga om passagerarkapacitet, komfort, räckvidd och motorteknologi. Flygplanstekniken i 747 kombinerade mekaniska och analoga system som kommunicerade genom särskilda vajrar, varierande strömstyrka och voltstyrka för att överföra information. Autopilotsystemet 747-200 bestod av över 20 separata datorer som skötte pitch, roll, gir, trim, gas och landningsfunktioner.

En fördel med detta var att om en dator slutade fungera var felet isolerat till endast en dator, och därmed var effekten inte så stor. Nackdelen var att systemen var så löst sammankopplade att autopiloten bara kunde användas vid några få tillfällen. Dessutom var flygbolagen tvungna att ha en mängd reservdatorer på lager. I slutet av 1960-talet var datorer en relativt ny produkt och de introducerades först inom kommersiellt flyg för att användas för navigation.

Navigation över långa avstånd ombord på 747 skedde med hjälp av ett system som inte gick att specialanpassa för olika ändamål och som byggts av Delco Electronics. Detta system, Inertial Navigation System (INS), var en riktig ingenjörspärla som först utvecklats för NASAs rymdprogram.

Systemet bestod av mekaniska gyron, analoga accelerometrar, analoga ”nätverk” och en dator som gjorde det möjligt att navigera för att flyga cirklar. Datorn inuti INS var en enkel aritmetisk och logisk enhet som kördes i hastigheten 3,0 MHz. Minnet, som hade storleken 6 kbyte, byggde på en litium-järnkärna och åtkomsttiden var runt 2-3 µs.

Tre INS-enheter installerades i varje 747 och det var nödvändigt att två var i funktion för att få flyga långa rutter. INS kunde köras med autopilot, men piloten var ändå tvungen att hålla uppsikt över flygplanets position väldigt noggrant eftersom noggrannheten hos en INS minskade när den använts en tid.
