  • Publication number: 20230400457
    Abstract: A disposable bioassay diagnostic cartridge for performing enzyme-linked immunosorbent assay for a single patient in whole blood and plasma where the cartridge has a plurality of wells. The cartridge includes a pipette tip with internal sidewalls disposed in one well of the plurality of wells, the internal sidewalls being pretreated and coated with antibodies, a reagent mixture disposed in another well of the plurality of wells, the reagent mixture comprising at least one reagent selected from the group consisting of pH stabilizer, ionic catalyst control agent, ionic intracellular inhibitory control agent, detergent, negative control agent, chelating agent, and biocide preservative, antibody, and conjugate stabilizing agent. At least a chromogenic substrate and visualizing reagent disposed in an integrated cuvette of the plurality of wells. It also includes the detection of the hemoglobin amount in the blood sample so a correction for plasma amount in a sample can be performed.

  • Publication number: 20230343493
    Abstract: In some embodiments, a multi-layer electrical device can include multiple electrodes connected to respective terminals, with at least two selected terminals being configured to allow movement relative to each other to accommodate a change in separation distance of the respective electrodes resulting from a change in temperature, and to allow a solder to provide a connection therebetween when the multi-layer electrical device is soldered on a mounting surface. In some embodiments, the multi-layer electrical device can further include a layer having a temperature-dependent electrical property implemented between each neighboring pair of electrodes.

  • Publication number: 20220373566
    Abstract: This invention relates to a method and apparatus for determining the activity of coagulation factors in dilute capillary whole blood, citrated whole blood and citrated plasma. It also includes the detection of the hemoglobin amount in a whole blood sample so a correction of the clotting time can be performed thereby making the clotting time values independent of hemoglobin and hematocrit effect.

  • Patent number: 8160392
    Abstract: Methods and systems can allow a user to avoid the inconvenience of selecting which of several computational photography techniques to apply when blending images. Instead, the user's workflow can be simplified in some cases and/or the image processing software can be less confusing to the user. For example, the user may import a set of images to image editing software. The software can automatically suggest a computational photography technique or techniques to apply to the set of images identified by the user. For example, the software may determine that the set of images comprise a stack or that the set of images comprise a panorama and suggest an appropriate technique for confirmation by the user. The software may apply the computational photography technique without the need for user intervention.

  • Patent number: 7764539
    Abstract: A spin-transfer MRAM is described that has two sub-cells each having a conductive spacer between an upper CPP cell and a lower MTJ cell. The two conductive spacers in each bit cell are linked by a transistor which is controlled by a write word line. The two CPP cells in each bit cell have different resistance states and the MTJ cell and CPP cell in each sub-cell have different resistance states. The MTJ free layer rotates in response to switching in the CPP free layer because of a large demagnetization field exerted by the CPP free layer. An improved circuit design is disclosed that enables a faster and more reliable read process since the reference is a second MTJ within the same bit cell. When RMTJ1>RMTJ2, the bit cell has a “0” state, and when RMTJ1<RMTJ2, the bit cell has a “1” state.
