摘要:
Systems and methods for assessing and optimizing virtual microscope slide image quality are provided. In order to determine whether any of multiple virtual slide images has an out of focus area and is therefore a candidate for manual inspection or rescanning, various focus points used to scan each virtual slide image are used to calculate a best fit surface for each virtual slide image. The best fit surface is then used to determine whether any of the various focus points are outliers. If it is determined that a virtual slide image is associated with outlying focus points, it is identified as a candidate for manual inspection or rescanning.

Systems and methods for assessing and optimizing virtual microscope slide image quality are provided. In order to determine whether a virtual slide image has any out of focus areas and is therefore a candidate for manual inspection, the various focus points used to scan the virtual slide image are used to calculate a best fit surface for the virtual slide image. The distance of each focus point from the best fit surface is then calculated and the largest distance is compared to a predetermined value. If the largest distance from a focus point to the best fit surface is larger than the predetermined value, then the virtual slide image is designated as needing a manual inspection and possible re-scan.

An electronically activated gas cooktop control system, responsive to a touch-sensitive user interface, and capable of providing a predetermined range of cooking and simmer levels of BTU output, has two complementary heating modes of operation A first heating mode of operation is provided to produce a wide selection of simmer levels of BTU output, by electronically sequencing a solenoid-operated modulating gas valve “on” and “off”, at a predetermined level of flame. A second cooking mode of operation is provided by electronically modulating the level of flame, through use of a pulse-width-modulation (PWM) output signal to produce a wide selection of cooking levels of BTU output. An igniter system capable of insuring proper ignition of gas without generating harmful electromagnetic interference is also provided.

Systems and methods for standardizing one or more fluorescence scanning instruments to a reference system by separating the effects of drift and normalization. In an embodiment, a drift image comprising an image of a drift reference slide is captured by a system to be standardized. A drift measurement is calculated using the drift image. A first normalization image comprising an image of a normalization slide is also captured by the system to be standardized. A reference normalization image, also comprising an image of the normalization slide, is captured by a reference system. The first normalization image is compared to the reference normalization image to determine a gamma value and offset value for the system to be standardized.

A loader arm assembly for use in a packaging system, comprising an arm, a housing, and a load jam detector. The housing is operably connected to at least one motive mechanism, and is adapted for moving the arm to load product into a package. The arm has both a latched state and a released state with respect to the housing. The arm normally is in the latched state to load product into the package, and enters the released state to relieve pressure upon detecting the load jam condition. The arm includes a base plate and a loading head. The housing is formed with a guide passage that is adapted for receiving the base plate. The load jam detector preferably includes at least one detent adapted for holding the base plate with respect to the housing in the latched state. The detent preferably is formed by a tip of at least one plug extending through the housing to the guide passage. The tip is adapted for applying a holding force against the base plate. A first end of the base plate has at least one depression adapted for receiving the tip of the at least one plug in the latched state and for releasing the tip to slide on a surface of the base plate upon the application of a predetermined load pressure attributable to the load condition. The loader arm assembly is described and shown within a barrel cam loading mechanism that is incorporated into a continuous motion packaging mechanism, but may be used in other packaging systems such as a vertical cartoner or a sleever.
