    摘要: Some embodiments include memory arrays. The memory arrays can have global bitlines extending along a first horizontal direction, vertical local bitlines extending perpendicularly from the global bitlines, and wordlines extending along a second horizontal direction which is perpendicular to the first horizontal direction. The global bitlines may be subdivided into a first series at a first elevational level, and a second series at a second elevational level which is different from the first elevational level. The global bitlines of the first series can alternate with the global bitlines of the second series. There can be memory cell material directly between the wordlines and the vertical local bitlines. The memory cell material may form a plurality of memory cells uniquely addressed by wordline/global bitline combinations. Some embodiments include cross-point memory cell units that have areas of about 2F2.

    摘要: A Compact Orthogonal Field Sensor for emitting two orthogonal electro-magnetic fields in a common space. More particularly, a replacement inductor for existing NMR (Nuclear Magnetic Resonance) sensors to allow for NMR imaging. The Compact Orthogonal Field Sensor has a conductive coil and a central conductor electrically connected in series. The central conductor is at least partially surrounded by the coil. The coil and central conductor are electrically or electro-magnetically connected to a device having a means for producing or inducing a current through the coil and central conductor. The Compact Orthogonal Field Sensor can be used in NMR imaging applications to determine the position and the associated NMR spectrum of a sample within the electro-magnetic field of the central conductor.

    摘要: An ultra-low magnetic field NMR system can non-invasively examine containers. Database matching techniques can then identify hazardous materials within the containers. Ultra-low field NMR systems are ideal for this purpose because they do not require large powerful magnets and because they can examine materials enclosed in conductive shells such as lead shells. The NMR examination technique can be combined with ultra-low field NMR imaging, where an NMR image is obtained and analyzed to identify target volumes. Spatial sensitivity encoding can also be used to identify target volumes. After the target volumes are identified the NMR measurement technique can be used to identify their contents.

    摘要: A radio-frequency tunable atomic magnetometer for detection of nuclear quadrupole resonance (NQR) from room temperature solids, including detection of nitrogen-containing explosives placed external to a sensor unit. A potassium radio-frequency magnetometer with sensitivity of 0.24 fT/Hz1/2 operating at 423 kHz is provided. The magnetometer detected a 14N NQR signal from room temperature ammonium nitrate (NH4NO3) in the zero-applied field limit. Results demonstrate first time detection of NQR with an atomic magnetometer, providing that a cryogen-free atomic magnetometer, with intrinsically frequency-independent sensitivity and easy tuning capabilities, can be an attractive new tool for detecting magnetic resonance signals in the kHz to MHz range. Low intensity magnetic fields are measured using an alkali metal vapor, by increasing magnetic polarization of the vapor to increase its sensitivity, then probing the magnetic polarization of the vapor to receive an output, and determining characteristics of the low intensity magnetic field from the output.
