This device is a Schottky-type diode with a continuously variable barrier height (variable over 0.5V) and nominally a three terminal variable barrier diode. The technology can be either permanently or reversibly switched, with potential application in multiple-state information storage. It may also be used in the fabrication of standard two terminal...

The Pupillary Dilation Response: A Tool for Assessing Sensory Performance in Humans

This tool demonstrates a correlation between the magnitude of a person’s involuntary pupil dilation and their hearing. A subject’s pupil size increases when they hear a sound, and the magnitude of the pupil increase is proportional to the intensity of the sound. The Pupillary Dilation Response tool can use this correlation to test hearing in patients...

Off-Resonant Receive Coil with Integrated Amplifier for Magnetic Resonance Imaging

Researchers at the University of Oregon have developed a new technology for reception and amplification of magnetic resonance images. Signal reception in magnetic resonance imaging relies on radio-frequency receive coils, the design of which is the single most important factor determining image quality. In recent years the use of arrays of receive...
