  • Publication number: 20130079613
    Abstract: Method and System for providing a signal from an insulin pump, artificial pancreas, or another insulin delivery device as a source of information for improving the accuracy of a continuous glucose sensor (CGS). The effect of using insulin information to enhance sensor accuracy is most prominent at low blood glucose levels, i.e. in the hypoglycemic range, which is critical for any treatment. A system for providing a filtering/state estimation methodology that may be used to determine a glucose state estimate at time t-?. The estimation may be extrapolated to some future time t and then the extrapolated value is used to extract the blood glucose component. The blood glucose component of the extrapolation and the output of the CGS are weighted and used to estimate the blood glucose level of a subject.

  • Publication number: 20130058157
    Abstract: The present invention proposes an electronic memory device comprising a memory line including a memory domain. The memory line may contain a number of memory domains and a number of fixed domains, wherein each memory domain stores a single binary bit value. A multiferroic element may be disposed proximate to each memory domain allowing the magnetization of the memory domain to be changed using a spin torque current, and ensuring the stability of the magnetization of the domain when it is not being written. The domain boundary between the memory domain and one of its adjacent fixed domains may thereby be moved. An antiferromagnetic element may be disposed proximate to each fixed domain to ensure the stability of the magnetization of these. The value of each memory domain may be read by applying a voltage to a magnetic tunnel junction comprising the memory domain and measuring the current flowing through it.

  • Publication number: 20130020297
    Abstract: The surface of a material is textured and by exposing the surface to pulses from an ultrafast laser. The laser treatment causes pillars to form on the treated surface. These pillars provide for greater light absorption. Texturing and crystallization can be carried out as a single step process. The crystallization of the material provides for higher electric conductivity and changes in optical and electronic properties of the material. The method may be performed in vacuum or a gaseous environment. The gaseous environment may aid in texturing and/or modifying physical and chemical properties of the surfaces. This method may be used on various material surfaces, such as semiconductors, metals and their alloys, ceramics, polymers, glasses, composites, as well as crystalline, nanocrystalline, polycrystalline, microcrystalline, and amorphous phases.
