Researchers at the University of California at Berkeley have developed a solar cell that they say offers a higher level of energy-conversion efficiency that mimics light-emitting diodes. The scientists hope the technology will lead to solar cells with an efficiency of nearly 30%, closer to the theoretical limit of 33.5% efficiency.
Renesas Electronics has introduced three power devices with multiple silicon carbide diodes and power transistors in one package. The chips are intended for applications in air conditioners, servers and solar power generation systems.
Infineon Technologies introduced a line of switch-mode light-emitting diode driver ICs for applications in LED lighting. The chipmaker says the devices could be used in commercial, residential and street lighting.
Samsung Electronics says it has commenced volume production on a wafer-fabrication line that will turn out flash-memory chips and DRAM using a 20-nanometer process for smartphones and tablet computers. The chipmaker's capital investment in the line is expected to reach $10.2 billion.
Blogger Loring Wirbel questions International Data Corp.'s recent report on "intelligent systems," noting that the market research firm lumped any product with a networked microprocessor into the category. While it's hard to get engineers to agree on what is or isn't an embedded system, Wirbel argues that a system's use of Ethernet and Internet protocol is more important when it comes to defining embedded systems.
