  • Publication number: 20190212210
    Abstract: A device for indicating violation of a temperature limit of an item is provided. The device is positionable near the item and includes a sensor configured to change its state permanently when the temperature limit is violated. The change in sensor state is machine-readable to provide a permanent indication of the temperature limit violation. The sensor includes a reservoir for storing a fluid that changes phase from a solid to a liquid when the temperature limit is violated and a channel in fluid communication with the reservoir for receiving flow of the fluid in liquid phase from the reservoir. The sensor is arranged to allow flow of the fluid in the liquid phase such that the state of the sensor is permanently changed. The sensor is further configured to prevent the fluid flow from permanently changing the sensor state until activation of the sensor from a resting state. A system and method for detecting violation of a temperature limit of an item using the device is also provided.

  • Publication number: 20190201912
    Abstract: A magnetic separation device for immunoassay using a two-sided plate for multi-well microplate separation via a flat side containing a magnetic block and a back side of magnetic microplate structure containing a matrix of permanent magnets. The present invention relates to a multi-purpose magnetic separation device that has two sides of magnetic separation function. The flat side of magnetic separation device includes magnet block, metal or plastic sheet on top surface and a pin to secure the assay plate. The back side of magnetic separation device is a multi-well structure that includes a plurality of permanent magnets placed in the spaces between the adjacent wells. There are different magnetic configurations for the multi-well structure, which ensures that each well is pulled by at least one strong permanent magnet. These strong permanent magnets are polarized laterally, i.e., its magnetic flux line points toward the side of the well.

  • Patent number: 9933926
    Abstract: A system for efficiently displaying medical data to a user. For one or more of the image series, the system displays a thumbnail image representing the image series in a secondary segment of a display. In response to a selection of one of the displayed thumbnail images the system displays in the secondary segment a positioning grid with multiple sections, each section representing a section of a separate primary segment of the display that does not overlap the secondary segment. In response to a selection of one of the sections in the positioning grid the system updates the display to cause an image in the image series corresponding to the selected thumbnail image to be displayed in the section of the primary segment of the display represented by the selected section of the positioning grid.
