  • Patent number: 9814403
    Abstract: A method of predicting substance levels from EEG data is disclosed. The method includes analyzing EEG data to obtain the average power for each of a plurality of predetermined frequency bands and calculating a value from the average powers derived for each frequency band, said value being calculated by combining the average powers for each frequency band by dividing and/or multiplying according to a predetermined order. The method further includes obtaining an estimate of the hormone level from the equation Y=bX+C, where Y is the substance level to be predicted, X is the value and b and C are constants, wherein the substance is selected from hormones, neuro transmitters and bio markers.
    Type: Grant

  • Patent number: 6515061
    Abstract: A paste composition having a high thermal conductivity and a relatively low viscosity is used to provide a thermal conductive connection between an electronic component and a cooling device to increase the heat transfer rate between the component and the device cooling the electronic component. The paste composition comprises a non-aqueous dielectric carrier, thermally conductive filler particles and a specially defined dispersant comprising the self-condensation reaction product of a hydroxy fatty acid, the reaction product having an acid number of about 30-100. A 12-hydroxy stearic acid self condensed reaction product is the preferred dispersant.

  • Patent number: 6228511
    Abstract: This invention relates generally to a structure and process for thin film interconnect, and more particularly to a structure and process for a multilayer thin film interconnect structure with improved dimensional stability and electrical performance. The invention further relates to a process of fabrication of the multilayer thin film structures. The individual thin film structure is termed a compensator, and functions as both a ground/reference plane and as a stabilizing entity with regard to dimensional integrity. The compensator is comprised primarily of a metal sheet having a metallized via pattern and high-temperature stable polymer as an insulator.

  • Patent number: 5976710
    Abstract: A multilevel high density interconnect structure of a semiconductor device or package including a substrate having at least one conductive feature therein, a film of a polyimide composition on the substrate and selected from the group consisting of a cured product of a polyamic acid and a cured product of a polyamic ester. The polyamic acid is prepared by reacting a stoichiometric excess of a linear aromatic diamine and aromatic dianhydride to form a first reaction product where the molar ratio of said diamine to said aromatic anhydride is in the range from 100:97 to 100:99.5 and then reacting the first reaction product with an aromatic anhydride. The polyamic ester is prepared by reacting a stoichiometric excess of a linear aromatic diamine and an aromatic diester diacyl chloride to form a second reaction product where the molar ratio of said diamine to said diester diacyl chloride is in the range from 100:97 to 100:99.5 and then reacting the second reaction product with aromatic anhydride.

  • Patent number: 5773561
    Abstract: The present invention relates generally to a new adhesive comprising a vinyl containing siloxane-containing polyimide for use in TSM capping of electronic package assemblies with adhesive capability of providing a seal band width of less than 4mm and even less than 2mm, solubility in non-toxic and environmentally safe solvents and durable adhesive properties and to a method for making the polyimides, a method for using the polyimides to make electronic packages and electronic packages made using the adhesive. The preferred vinyl-containing siloxane containing polyimide is a block type polymer containing blocks of a dianhydride-aromatic diamine oligomeric reaction product joined by non-vinyl/vinyl containing siloxane diamine forming links.
