CMR Releases Desktop Magnetic Printer for
Advanced Magnetics Assemblies
Correlated Magnetics Research (CMR) has released the desktop
version of its precision magnetizer. The Mini MagPrinter is targeted
toward product design and prototyping with customized magnets
made possible by CMR's new magnetics technology. The Mini MagPrinter system includes CMR's Polymagnet Catalog of pre-engineered magnetic functions, and the design software to customize
magnet strength and behavior.
The Mini MagPrinter is a
rapid-prototyping magnetization system that "prints"
arrays of magnetic regions
onto a single piece of magnetic material to produce a
Polymagnet. A Polymagnet is
a patterned magnet tailored
to perform novel magnetic
functions that designers can
integrate into consumer and industrial products. Each Polymagnet
is a system of smaller magnets, both north and south poles, that
are imprinted by the MagPrinter. A conventional magnet can be
turned into a Polymagnet by placing the magnet into the MagPrinter, choosing a pattern from the Polymagnet Catalog and re-programming the magnet to exhibit a number of different functions.
The Mini MagPrinter produces Polymagnets on the strongest Neodymium magnets, flexible materials, ferrites and specialized materials such as samarium cobalt.
"CMR's first MagPrinter made programmable magnet systems
possible by defining magnets in software for variable strength,
reach and function. Defining a magnet in software is a huge improvement over conventional magnets, which are defined simply by
their size and grade," said Andy Keane, president and CEO of Correlated Magnetics Research. "Our new desktop MagPrinter will do for
magnetics what 3D printing systems did for mechanical prototyping. Designers now have a powerful prototyping tool for programmable magnetics in an affordable desktop system that is perfect for
consumer and industrial engineering teams."
Polymagnet applications range from advanced functions not
possible with conventional magnets to very high strength magnets
for traditional attachment. With more sophisticated patterns, Polymagnets behave as magnetic springs, latches or connectors that
self-align with very high precision. When used for attachment, a
Polymagnet concentrates the strength near the surface of the magnet. This not only increases the attachment strength more than five
times that of a conventional magnet, but it also reduces the risk
to magnetically sensitive electronics and the accidental attraction
of nearby metal or other magnets. All of these behaviors can be
customized using CMR's Polymagnet design software.
Bruker Installs Compact 900 MHz Actively
Refrigerated Magnet for NMR Spectroscopy
Bruker Corp. has announced the successful installation of an
Ascend Aeon 900 magnet, the first compact, single-story NMR
magnet with active refrigeration at the University of California,
San Diego (UCSD). The Aeon technology integrates advanced
refrigeration technology into the magnet design, thus providing
independence from the periodic cryogen refills customary with
traditional NMR magnets.
The Ascend Aeon 900 is a liquid nitrogen-free, superconducting
magnet system with helium reliquefaction technology. It enables

long-term, carefree operation
without user maintenance and
with essentially helium-consumption-free operation. Whereas
traditional 900 MHz magnets require two-story laboratories, the
new compact Ascend Aeon 900
magnet can be placed in singlestory labs due to advancements
in superconductors, jointing technologies and novel magnet designs. Researchers with restricted
laboratory space can now benefit
from the sensitivity and dispersion of ultra-high field solid-state
NMR with this first ever singlestory 900 MHz magnet. The reduced height and minimum stray
magnetic fields of this magnet
maximize siting flexibility and reduce site preparation costs.
With the introduction of Aeon technology for 400 to 700 MHz
NMR magnets earlier this year, and now the Ascend Aeon 900, Bruker
continues to respond to concerns regarding potential Helium shortages and increasing Helium costs. Ascend Aeon magnets achieve this
by combining the latest active-shielding technology with Bruker's advanced, proprietary refrigeration designs, featuring integrated lowvibration cryo-coolers for reliable long-term operation.
The University of California, San Diego purchased the Ascend
Aeon 900 magnet together with Bruker's AVANCE III HD NMR spectrometer to provide NMR capabilities at the UCSD Biomedical Technology Research Center (BTRC) for Molecular Imaging of Proteins.
The instrument will be used for the development and application
of high-resolution solid-state NMR spectroscopy to proteins in biological supramolecular assemblies, especially membranes. The Collaborative and Service activities of the BTRC ensure that the instrument is available to the UCSD biomedical research community.
New Miniature, 3.3 V Linear Hall-Effect Sensor IC
Allegro MicroSystems, LLC has introduced a linear, Hall-effect sensor IC specifically designed for applications that require medium accuracy in a very small package. Allegro's A1304 is a factory trimmed
one-time programmable (OTP-ROM)
3.3 V linear Halleffect sensor integrated
that eliminates the
need for customers
to program the device to compensate
effects on sensor
device has been
designed for both consumer and industrial markets, and consequently
supports an industrial temperature range of -40°C to 85°C.
Allegro's A1304 has a typical programmable sensitivity level of 4
mV/G ±6 percent. Sensitivity and QVO TC are blind blown (trimmed)
at the factory for improved accuracy relative to other low cost linear IC's from Allegro (A1301/02). A1304 device complements Al-
