  • Patent number: 7173179
    Abstract: A solar co-generator for producing both heat energy and electricity is disclosed. A solar concentrator directs sunlight into a container lined with solar cells and filled with a thermal transfer fluid. The fluid is transparent with respect to certain wavelengths of light that may be converted to electricity by the solar cell, but is opaque with respect to longer wavelengths, particular the infrared band. The infrared portion of the sunlight heats the thermal transfer fluid, which then transfer that heat through a storage facility using a heat exchange mechanism. The thermal transfer fluid increases the efficiency of photovoltaic generation by preventing heating of the solar cells due to infrared radiation. The thermal transfer fluid may be a mixture containing barium sulfate and a suspension of zinc sulfide phosphors. A fluorescing anti-reflective coating may be applied to the solar cells to further increase efficiency.

  • Patent number: 6993377
    Abstract: A method of analyzing electrocardiogram (EKG) data for use in the diagnosis of heart disease, prognosis of cardiac conditions, and the monitoring of heart disease therapies is disclosed. The method utilizes a wavelet-based multifractal analysis with one or more of (1) a discrete wavelet smoothing step to remove the effects of abnormal beats; (2) “Levy flight” analysis to detect the frequency of abnormal beats known to adversely affect the multifractal (MF) analysis; and (3) MF alpha analysis, a multifractal extension of monofractal short term (ST) alpha analysis. The invention further comprises an EKG test battery comprising Levy flight anomalous beat/beat cluster screening, followed by (ST) MF alpha analysis and MF Holder analysis (when validated by the Levy flight analysis). The wavelet smoothing step can also be used to classify human EKGs by observing the effect of sequential smoothing on the MF Holder coefficient.

  • Patent number: 6802919
    Abstract: A method for sealing a container comprising a cup and lid is disclosed. The cup has a lip with a raised sealing bead along its length. During sealing, the raised sealing bead compresses, thereby stretching the adhesive layer on the lower portion of the lid out of the way and forming a direct welded seal with the heat-resistant layer of the lid. The adhesive to either side of the sealing bead forms an adhesive seal between the lid and the remaining portion of the lip. This type of double seal is particularly effective in forming a durable, consistent seal when product is present on the lip of the container. The welded seal is also well suited to situations when the cup may be warped or the sealing bead is otherwise caused to be higher along some portion of its length than along other portions.
