  • Patent number: 6586133
    Abstract: A nano-battery or micro-battery produced by a process which includes the steps of providing a membrane with a plurality of pores, filling the membrane pores with an electrolyte, and capping the filled pores with electrodes in communication with the electrolyte to form nano-batteries or micro-batteries.

  • Patent number: 6471864
    Abstract: Highly porous, adsorbent biocatalyst beads of poly(hexamethyleneadipamide) or poly(caproamide) polymer having powdered activated carbon dispersed throughout the polymer and biocatalytic material, such as bacteria, located within macropores of the beads, are highly useful and relatively inexpensive polymeric beads, compared to similar known aramid beads, in removing organic and/or some inorganic contaminants from aqueous streams. The biocatalytic material consumes the organic and/or some inorganic contaminants which are adsorbed by the activated carbon and metabolizes the contaminant into harmless products, while continuously renewing the adsorptive capacity of the activated carbon.

  • Patent number: 6181647
    Abstract: A method to measure height of a vertical jump of a jumper. At least one switch is deactivated by the jumper stepping thereon. The switch is initially activated by the jumper jumping upward therefrom and thereafter deactivated upon return. A time period is measured while the switch is activated. The square of the activated time period is calculated and thereafter the result is multiplied by a constant to derive vertical jump height. Finally, the resultant vertical jump height of the jump is displayed.

  • Patent number: 6025128
    Abstract: A method for screening individuals at risk for prostate cancer progression is disclosed. The method is useful for evaluating cells from patients at risk for recurrence of prostate cancer following surgery for prostate cancer. Specifically, the method uses specific Markovian nuclear texture factors, alone or in combination with other biomarkers, to determine whether the cancer will progress or lose organ confinement. In addition, methods of predicting the development of fatal metastatic disease by statistical analysis of selected biomarkers is also disclosed. The invention also contemplates a method that uses a neural network to analyze and interpret cell morphology data. Utilizing Markovian factors and other biomarkers as parameters, the network is first trained with a sets of cell data from known progressors and known non-progressors. The trained network is then used to predict prostate cancer progression in patient samples.

  • Patent number: 5932082
    Abstract: An improved electroplating bath, complexing agent, product and method for producing nickel-rich nickel-iron alloys, such as Permalloy, having about 22% iron and 78% nickel. The improved electroplating bath contains a small amount of an organic amine complexing agent such as ethylenediamine or diethylenetriamine which increases the nickel/iron mass ratio of the deposit, causes nickel to be deposited in favor of iron, reduces the sensitivity of the deposit composition to the iron content of the bath and the applied current density. Further, the pH of the bath is adjusted to about 5.0 to stabilize the complexes and tartaric acid is added to complex ferric ion and thus prevent its precipitation. The organic amine complexing agents useful in accordance with the present invention are agents which complex with nickel and include ethylenediamine and diethylenetriamine each having at least two amine groups with each of the amine groups separated by two carbons.

  • Patent number: 5798463
    Abstract: A tensile test fixture for applying constant tensile forces to a tensile test specimen comprises two mounting grips, each mounted to one of two lever arms in a pivoted lever arm frame structure. One end of each lever arm is pivotally attached to a compression column while the other end of each lever arm is attached to one end of a force-applying assembly. The mounting grips are pivotally attached to their respective lever arms between the compression column and the force-applying assembly and are designed to hold opposite ends of a tensile test specimen. The force-applying assembly comprises stress and strain modules that are interchangeably installable into the force-applying assembly to selectively subject tensile test specimens to constant strain and constant stress.
