  • Patent number: 8791444
    Abstract: Resistive random access memory (RRAM) using stacked dielectrics and a method for manufacturing the same are disclosed, where a setting power of only 4 ?W, an ultra-low reset power of 2 nW, good switching uniformity and excellent cycling endurance up to 5×109 cycles were achieved simultaneously. Such record high performances were reached in a Ni/GeOx/nano-crystal-TiO2/TaON/TaN RRAM device, where the excellent endurance is 4˜6 orders of magnitude larger than existing Flash memory. The very long endurance and low switching energy RRAM is not only satisfactory for portable SSD in a computer, but may also create new applications such as being used for a Data Center to replace high power consumption hard discs.

  • Patent number: 7215122
    Abstract: The subject invention relates to a method and apparatus for producing stimulated MRI data. In an embodiment, a remote-controlled “smart phantom” can produce simulated data. The simulated data can be acquired from a MRI system. The subject device can generate control signals and send the generated control signals to secondary coils/probes placed in the subject smart phantom. The control signals determine the current flow in the secondary coils/probes, which act as local spin magnetization amplifiers and thus produce regions of variable contrast to noise ratio. The control signals can be generated with various parameters, such as BOLD models, different levels of contrast-to-noise ratio (CNR), signal intensities, and physiological signals. Comparisons can be made with the widely-used simulated data by computers. Validation of the subject smart phantom can be performed with both theoretical analysis and data of human subjects.

  • Publication number: 20060233454
    Abstract: The subject invention pertains to a method of image intensity correction. The subject invention can utilize extrapolation for image intensity correction. The use of extrapolation can reduce the artifacts during intensity correction as compared to traditional methods of intensity correction. The extrapolation can be combined with, for example, homomorphic filtering methods, parametric estimation techniques, wavelet based method, and/or Gaussian smooth method, in order to reduce the artifacts generated by these methods and improve the quality of correction. The implementation of image extrapolation in accordance with a specific embodiment can utilize closest point method. The subject method can also use adaptive smoothing for image intensity correction. In an embodiment, the use of gradient weighted smoothing method can reduce, or eliminate, over-smoothing of bright spot regions. In a specific embodiment, the subject method can utilize gradient weighted partial differential equation (PDE) smoothing.
