Embedded
vision is poised to enable the next generation of electronic-system
success stories. Embedded vision got its start in traditional computer
vision applications such as assembly line inspection, optical character
recognition, robotics, surveillance and military systems. Read the
Xilinx approach here.
Reasonably priced sensors are now available in a variety of packages,
making them attractive for a wide variety of embedded system precision
sensing applications, including liquid level measurements. This article
from Maxim Integrated Products describes differences among modern
pressure sensors and emphasizes the benefits of recent advances in
microelectromechanical (MEMS) temperature-compensated, silicon pressure
sensors.
Today's multi-cell lithium battery designs in portable industrial and
medical equipment need a more accurate way to measure remaining battery
capacity. Texas
Instruments has introduced the first in a family of
multi-chemistry, multi-cell battery management gas gauge circuits using
the company's proprietary impedance track capacity measurement
technology.
China and the United States are the two countries most likely to come
up with "disruptive technology breakthroughs" with a global
impact in the next two to four years, according to a survey conducted
by auditor and consultancy KPMG (Amstelveen, Netherlands). Read China,
U.S. lead innovation, Europe nowhere, says survey.
