2U Zhou Enlai CubeSat, developed with primary and middle school students
in China, is expected to launch on January 19. The satellite is named after the first
Premier of the People’s Republic of China, who held office from 1949 until 1976. A report
on the official Xinhua Net website said the CubeSat, constructed at Huai'an Youth Comprehensive
Development Base in Jiangsu Province, has been transported to Jiuquan Satellite Launch
Center, where a CZ-11 solid-fuel rocket will put it into orbit Friday. 'Twenty teenagers
who participated in the development project ..."
Tesla Model S reportedly on 'Autopilot' smashed into the back of
a fire truck parked at a freeway accident scene Monday morning, authorities said. The
union representing Culver City firefighters whose truck was hit around 8:30 a.m. on Interstate
405 in Culver City tweeted that the Tesla driver said he had been using Tesla's Autopilot
system, which performs automated driving tasks. The CHP and Culver City Fire Department
confirmed the southbound Tesla had struck the fire truck, but could not immediately ...
This is Part 2 of a 3-part series of articles on
atomic radiation that appeared in Electronics World magazine in 1969. The
first part, which dealt with various types of radiation and how they interacted with
matter, was posted a week or so ago. For instance ionizing versus nonionizing radiation,
where the former can cause cancer, the latter just burns you. This installment discuses
methods and equipment for detecting and measuring radiation levels. Ionizing radiation
detectors rely on having massive particles impinge on gas, solid, or liquid media and
causing a reaction that is visible or measurable by electronic means. Nowadays there
are highly ...
This quiz tests your awareness of the many
mergers and acquisitions that occurred in the RF, microwave, and analog electronics
industries during 2017. Mr. Raghav Kapur, of the everythingRF website, compiled
a good list of events with a short description of the transactions, so I used it to generate
this 10-question quiz. It was made using Google Docs. Winners receive a free subscription
to the RF Cafe website for a full month. Good luck ...
At least 10 clues with an asterisk (*)
technology-themed crossword puzzle are pulled from this past week's (1/15 - 1/19)

astronomy, etc. Enjoy!
"Researchers have developed the world's first
complementary electrochemical logic circuits that can function stably for long periods
in water. This is a highly significant breakthrough in the development of
bioelectronics. The first printable organic electrochemical transistors
were presented by researchers at LiU as early as 2002, and research since then has progressed
rapidly. Several organic electronic components, such as light-emitting diodes and electrochromic
displays, are already commercially available. The dominating material used until now
has been PEDOT:PSS, which ..."

the same experienced leadership team, but we will have a broader scope and an expanded
product portfolio. When Murata acquired Peregrine in Deceember 2014, they kept the Peregrine
brand name untouched. In the last few years, Murata has asked our team to extend our
reach, increase our intellectual property ...
"You don't have to be perfectly organized to pull
off a wave, according to scientists. Using a set of gyroscopes linked together, physicists
explored the behavior of a material whose structure is arranged randomly, instead of
an orderly lattice. They found they could set off one-way ripples around the edges, much
like spectators in a sports arena - a 'topological wave,' characteristic of a particularly
unusual state of matter. Using a set of
gyroscopes linked together, physicists explored the behavior of a
material whose structure is arranged randomly, instead of an orderly lattice. They found
they could set off one-way ..."
By now, most people involved with spread spectrum
communications are (or should be) aware that Hollywood starlet
Hedy Lamarr is credited
for being the first to suggest a frequency hopping scheme for secure communications.
If you do a Google search on Hedy Lamarr and spread spectrum, you see that except for
a few mentions on tech websites, it has only been in the news since the end of the last
decade. Scientific American magazine ran an article titled, "Hedy Lamarr: Not
Just a Pretty Face," in 2008. Google honored her in 2015 with a Doodle on their homepage.
"The most beautiful woman in the world," with the assistance of her co-inventor-composer
George Antheil ...

EIRP - effective isotropic radiated power - is
an important parameter when calculating both intentional and unintentional electromagnetic
emissions. EIRP is a vector quantity that accounts for both power (magnitude) and 3-dimensional
coordinates (direction). It includes antenna directivity that concentrates power in a
particular direction rather than distributing it equally in all directions (e.g., isotropically).
Effective radiated power factors in modulation type and power envelope shape as well.
Knowing how to measure that quantities can make the difference between ...

How Technology Is Changing the Manufacturing Workforce
Analog Devices announces the
LTC5562, a low power,
high performance active double-balanced mixer, capable of 50 Ω matching over a very
wide frequency range of 30 MHz to 7 GHz. This versatile mixer can be used in
either frequency upconversion or downconversion applications, with outstanding conversion
gain of 2 dB. The device runs on a single 3.3 V supply rail, drawing 40mA nominal
operating current. If lower power consumption is needed, the mixer can be configured
to operate as low as 15 mA, supporting a wide ...
As with most technologies that have been around
for decades, the fundamentals of
crystal filters have not changed with time. Materials and methods have changed, of
course, but the equivalent lumped element model (using resistors, capacitors and inductors)
of a crystal filter is essentially the same today as it was in 1969 when this article
appeared in Electronics World magazine. Open a first semester electronics circuits
textbook and the chapter on crystals will look much like this piece by Mr. Robert Kent,
of Damon Engineering. The use of crystal had a profound impact on filter design because
their extremely high "Q" factors ...

"Scientists from Duke University and Oak Ridge
National Laboratory have collaborated on a project that seeks to determine the atomic
mechanisms of a very rare type of
electric field. Everlasting electric fields have not been well-researched
at this point, but the findings in this new project are an impressive step forward. Researchers
hope to develop new materials that have similar properties, which could be used in a
variety of applications. Scientists uncovered the atomic properties by ricocheting neutrons
off the atoms of yttrium manganite. The material was heated to 3,000° Fahrenheit ..."
