  • Publication number: 20060178958
    Abstract: Systems and methods are provided for data processing. In one implementation, a data processing system includes storage means for storing sets of account identifiers, each of the sets of account identifiers being assigned a set of control parameters. The data processing system may also include an account management system that stores account data of accounts that are identified by the account identifiers, interface means coupled to the account management system, and one or more sets of application programs that are adapted to process account data of accounts identified by at least one of the one or more sets of account identifiers using the set of control parameters assigned to the at least one of the one or more sets of account identifiers. The interface means may obtain the account data from the account management system on request of one of the application programs.

  • Publication number: 20060006141
    Abstract: Methods for fabricating a plurality of sensors on a flexible substrate, with each sensor having associated electrodes and at least one well include (a) providing a flexible substrate material layer having a surface area defined by a length and width thereof; (b) forming a plurality of sensor elements onto the flexible substrate material layer, each sensor element comprising at least one metallic electrode; (c) disposing at least one coverlay sheet layer over the flexible substrate sandwiching the sensor elements therebetween; (d) laminating the at least one coverlay sheet layer having an associated thickness to the flexible substrate; and (e) removing predetermined regions of the laminated coverlay sheet layer from the flexible substrate laycr to expose a portion of the underlying metallic pattern of each sensor element and to define a well with a depth corresponding to the thickness of the coverlay sheet layer.

  • Patent number: 6843899
    Abstract: Chemical sensors include a flexible substrate, a flexible lower electrode on the flexible substrate, and a patterned flexible dielectric layer on the flexible lower electrode opposite the flexible substrate. A patterned flexible upper electrode also is included on the patterned flexible dielectric layer opposite the flexible lower electrode. The patterned flexible dielectric layer and the patterned flexible upper electrode are patterned to establish a first current flow path between the flexible lower electrode and the patterned flexible upper electrode through the chemical, if present, upon application of voltage between the flexible lower electrode and the patterned flexible upper electrode. The flexible lower electrode also may be patterned to establish a second current flow path between portions of the patterned flexible lower electrode through the chemical, if present, upon application of voltage between the portions of the patterned flexible lower electrodes.

  • Patent number: 6627034
    Abstract: A method of forming a laminate structure comprises providing a first substrate and a second substrate each having first and second substrate surfaces respectively, and wherein the surfaces are present in an opposed spaced apart relationship; contacting at least one of the first or second substrate surfaces with a release material such that a portion of the first or second substrate surface is covered with the release material while the remainder of the first or second substrate surface is not covered with the release material; bringing the first and second substrate surfaces of the first and second substrates into contact with each other; and subjecting the substrates to conditions such that the portions of the first and second substrate surfaces not covered with release material become bonded to one another and a laminate structure is formed.
