PUSH FOR POWER EFFICIENCY - FORCES CHANGES IN SERVER-CENTER HARDWARE AND SOFTWARE

- INDUSTRY INITIATIVES, SUCH AS THE GREEN GRID AND CLIMATE SAVERS, HAVE SET THE AMBITIOUS GOAL OF HALVING DATA-CENTER ENERGY USAGE BY 2011. TO ACHIEVE THIS OBJECTIVE, THE INDUSTRY MUST SHIFT TO THE USE OF DIGITAL-POWER CONTROL AND MANAGEMENT AT THE AC/DC- AND DC/DCPOWER- SUPPLY LEVEL. A SHIFT TO DC-BU
INDUSTRY INITIATIVES, SUCH AS THE GREEN GRID AND CLIMATE SAVERS, HAVE SET THE AMBITIOUS GOAL OF HALVING DATA-CENTER ENERGY USAGE BY 2011. TO ACHIEVE THIS OBJECTIVE, THE INDUSTRY MUST SHIFT TO THE USE OF DIGITAL-POWER CONTROL AND MANAGEMENT AT THE AC/DC- AND DC/DCPOWER- SUPPLY LEVEL. A SHIFT TO DC-BUS-POWER DISTRIBUTION WITHIN THE DATA-CENTER INFRASTRUCTURE ALSO SHOWS PROMISE.

Testing the FlexRay automotive bus

- BY JOHNNIE HANCOCK • AGILENT TECHNOLOGIES
IN RECENT YEARS, THE EVENT-DRIVEN CAN (CONTROLLER-AREA-NETWORK) SERIAL BUS HAS BECOME THE COMMUNICATIONS BACKBONE FOR AUTOMOTIVE ELECTRONICS, PROVIDING THE INTERACTION BETWEEN THE MANY SEPARATE SENSORS AND ACTUATORS, AND THE ECU. HOWEVER, AS COMMUNICATIONS SPEEDS HAVE INCREASED AND AUTOMOTIVE ELECTRONICS HAVE EXPANDED INTO MORE— AND MORE SAFETYCRITICAL— AREAS, THERE HAS BEEN A SHIFT IN THE TECHNOLOGY.

Location systems find their way in the world

- BY GRAHAM PROPHET • EDITOR
SAY THE WORD LOCATION AND MANY ENGINEERS’ INSTANT REACTION IS TO THINK OF SATELLITEBASED GPS. BUT A NUMBER OF OTHER TECHNOLOGIES ARE EMERGING TO PROVIDE LOCATION INFORMATION AT SCALES THAT RANGE FROM GLOBAL DOWN TO CENTIMETRIC. MOBILE SYSTEMS THAT KNOW WHERE THEY ARE, AND FIXED SYSTEMS THAT KNOW THE WHEREABOUTS OF THEIR MOBILE ASSETS, UNDERPIN A BROAD RANGE OF NEW PRODUCT CONCEPTS.
