EDEN PRAIRIE, Minn., May 30 /PRNewswire-FirstCall/
-- NVE Corporation ( NASDAQ:NVEC )
said that it has been notified by the U.S. Patent
and Trademark Office (USPTO) that two patents are
expected to be granted today. The patents are titled "Two-Axis
Magnetic Field Sensor" and "Superparamagnetic Devices."
The Two-Axis Magnetic Field Sensor is patent number
7,054,114, and is the grant of a patent under the
application published by the USPTO as number 2004-0137275.
The invention is for a spintronic device that can
detect the magnitude and orientation of magnetic
fields. Applications for such devices might include
Magnetoresitive Random Access Memory (MRAM), or military,
industrial, and medical sensors.
The Superparamagnetic Devices patent is number 7,054,118
and is the first patent granted from the application
published by the USPTO under number 2004-0023065.
Other patents are possible based on this application,
although there can be no assurance if or when additional
patents will be granted.
Superparamagnetism is the magnetic state of a material
between highly ordered parallel spins (ferromagnetism)
and randomly ordered spins (paramagnetism). The superparamagnetic
effect occurs in ferromagnetic particles smaller
than a critical value or at temperatures higher than
a critical temperature. In conventional storage systems
such as disk drives, superparamagnetism can be undesirable
because it limits storage density. The NVE invention
utilizes the superparamagnetic effect to improve
the accuracy of spintronic sensors where a small
sensed field is sufficient to order the spins in
a superparamagnetic material. More accurate sensors
would be useful in a number of applications including
military, medical, and biosensor.
The grants will bring NVE's U.S. patent total to
38. The company has more than 100 patents worldwide
issued, pending, or licensed from others. Links to
the new patents and NVE's other U.S. patents can
be found at the "About NVE" section of the company's
Website ( http://www.nve.com/ ).
NVE is a leader in the practical commercialization
of spintronics, a nanotechnology that many experts
believe represents the next generation of microelectronics.
NVE licenses its MRAM intellectual property and sells
spintronic products, including sensors and couplers,
to revolutionize data sensing and transmission.
