The invention relates to methods and systems for generating negative controls for arrays. In an embodiment, the invention includes a method for generating a negative control probe sequence for an array including randomly generating a plurality of candidate negative control probes, screening the candidate negative control probes for sequence similarity to biologically occurring sequences, and screening the candidate negative control probes for one or more of base composition properties, primary structural features, secondary structural features, or thermodynamic characteristics. In an embodiment, the invention includes an apparatus for generating a negative control sequence for an array. The apparatus including a memory store and a programmable circuit in electrical communication with the memory store, the programmable circuit programmed to randomly generate a plurality of candidate probe sequences, screen the candidate probe sequences for sequence similarity to biologically occurring sequences, and screen the candidate probe sequences for one or more of base composition properties, primary structural features, secondary structural features, or thermodynamic characteristics.

Methods, systems and machine-readable instructions for processing an electronic document are described. In one aspect, logical blocks that were extracted from the electronic document, including a text block comprising text lines each encompassed by a respective bounding rectangle, are received. Edges of ones of the bounding rectangles are extended to at least one boundary without changing layout relationships among the logical blocks in the electronic document. A text layout boundary is generated from extended and unextended edges of the bounding rectangles. A description of the text layout boundary is stored in a machine-readable medium.

A connector assembly for a planar sensing element of an exhaust gas sensor is shown, with a method for assembling. There is an opposed pair of ceramic clamshells which retain terminals, each terminal mates to corresponding contact pads of the planar sensing element. A spacer is positioned between clamshells and a seal. A retainer clip binds the ceramic clamshells. These components are contained within an upper shield, upon assembly. The spacer creates a hinge point between the clamshell devices, allowing insertion of the sensing element without abrasion or scraping of the contact pads against the terminals The retainer clip, with radially extending tabs, keeps the opposed pair of ceramic clamshells under compression upon the sensing element when assembled, due to an interference fit with the upper shield of the sensor.

Methods, systems and computer readable media for downloading data to file depository managed on a server. A user locates a remote server that hosts a file to be downloaded to the file depository using a web browser. A download request is submitted to the download queue, wherein the download queue is executed to download the file into the file depository. The system checks remote FTP sites and updates its file depository at specific intervals set by users and downloads the latest version of its file and archives old versions. The system allows users to upload files from the file depository to remote servers and updates the file depository if the file transfer was successful. All file transfer history for downloads/uploads may be viewable by client users.

A resistor assembly, comprising: a housing body having a recess defined by a peripheral edge; a pair of channels disposed in the peripheral edge, the pair of channels extending from the recess and through the peripheral edge; a trim resistor element disposed in the recess, the trim resistor element comprising a nonconductive support surface, a pair of conductive pads disposed on the nonconductive support surface, the pair of conductive pads being disposed in a spaced relationship on the nonconductive support surface, and a trimable resistive film disposed on the nonconductive support surface, the trimable resistive film being in electrical communication with each of the pair of conductive pads at separate locations to provide a conductive path between the pair of conductive pads through the trimable resistive film; a pair of lead wires, each lead wire comprising an electrically insulative sheath disposed about a metallic wire, each lead wire further comprising a terminal section formed of an exposed metallic wire stripped of the electrically insulative sheath, wherein each wire is arranged with the housing body such that the insulative sheath is received in one of the pair of channels and the terminal section extends into the recess to make electrical contact with a respective one of the pair of conductive pads; a housing top fixed to the housing body, the housing top having a first top portion and a second top portion, the first top portion overlying a portion of the pair of lead wires and clamping the electrically insulated sheath within a respective one of the pair of channels and the terminal section against a respective one of the pair of conductive pads, the housing top further comprising a second top portion, the second top portion having an opening defined by a perimeter, the opening overlying and exposing the trimable resistive element and the perimeter overlying a portion of the trim resistive element to retain the resistive element within the recess.
摘要:
An electrical connection is made by connecting a metal element to a second element to which the electrical connection is desired to be made by means of a conductive material disposed onto one or both of the metal element and the second element so as to contact and disperse about or through the metal element thereby providing both an electrical and a mechanical connection. The metal element may be a strip or pad with openings or knurls formed such as by stamping, a wire that is flattened and knurled, or a mesh material such as a wire mesh. In a preferred embodiment, the conductive material is a metal capable of withstanding harsh, high temperature environments, such as a noble metal. In another preferred embodiment, the second element is a ceramic element, preferably with a noble metal conductive pad thereon, to which the metal element is attached.

Systems and techniques to allow a user to design and manage business solutions. The business solution management system (150) comprises a portal layer (112), an application layer (104) and a data repository (106). The portal layer (112) comprises at least first and second agents (204, 208). The application layer (104) comprises at least first and second software applications (220, 224). The first and second agents (204, 208) provide user interfaces to the first and second software applications (220, 224). The first software application (220) is operable to allow a user to design a business solution with user parameters and user-selectable, pre-defined business process objects and pre-defined technology objects. The second software application (224) is operable to allow a user to manage the business solution. The data repository (106) comprises the pre-defined business objects (316) and pre-defined technology objects (314).
