    摘要： A routing plane includes an authentication packaging system that receives client authentication information, as part of a request from a requesting client that is to be routed to a target service. The authentication packaging system combines the authentication information with assertion information indicative of an assertion as to the identity of the routing plane, using an entropy, such as a signing key. The authentication package is attached to the request and is sent to the target service. The target service validates the authentication package based on the entropy and authenticates the routing plane based on the assertion information and performs authentication processing based on the authentication information.

    摘要： A system for measuring solder paste stencil aperture positions and sizes is provided. The system includes at least one camera configured to acquire images of the stencil and an alignment target. A motion system generates relative motion between the at least one camera and the stencil. A controller is coupled to and controls the motion system. The controller is configured to analyze the images to generate aperture information relative to the stencil. The aperture information is provided to automatically program a solder paste inspection system. Other features and benefits that characterize embodiments of the present invention will be apparent upon reading the following detailed description and review of the associated drawings.

    摘要： A process analytic system includes an analytic sensor configured to sense a characteristic of a fluid. The process analytic system also includes measurement circuitry coupled to the analytic sensor and configured to generate an indication of the characteristic of the fluid. The process analytic system includes a processor coupled to the measurement circuitry and configured to receive the indication of the characteristic of the fluid and calculate a sensor-related output based on the indication of the characteristic of the fluid. In addition, the process analytic system includes a diagnostics component configured to determine a rate of degradation of the analytic sensor based on the sensor-related output and a reference value, wherein the rate of degradation is compared to a pre-selected threshold.

    摘要： A colorimetric analyzer includes a reaction chamber configured to receive a sample and at least one reagent. A measurement cell is operably coupled to the reaction chamber. The measurement cell has an illumination source and an illumination detector spaced from the illumination source such that illumination from the illumination source passes through the reacted sample to the illumination detector. A controller is coupled to the illumination source and the illumination detector. The controller is configured to generate an analytic output based on a signal from the illumination detector. A fill conduit is operably interposed between the reaction chamber and the measurement cell. The fill conduit is configured to reduce bubbles.
