  • Patent number: 11932365
    Abstract: An apparatus that facilitates search and rescue, for example, in open water. The apparatus comprises a substrate with a particular geometry and a perimeter. The apparatus further comprises a cover positioned atop the substrate with the cover also having a particular geometry and perimeter, which correspond to the geometry and perimeter of the substrate. An air-tight seal seals the substrate perimeter to the cover perimeter and creates a sealed internal region. A liquid-releasable vessel holding an illuminable dye located in the sealed internal region, along with an activator that is also located in the sealed internal region. When the liquid-releasable vessel releases the illuminable dye, the illuminable dye reacts with the activator, thereby resulting in illumination of the illuminable dye. The liquid-releasable vessel comprises an opening with a release mechanism (e.g., clamp, etc.).

  • Patent number: 9725762
    Abstract: Systems and methods for processing sample processing devices. The system can include a sample processing device comprising a detection chamber, a motor configured to rotate the sample processing device about an axis of rotation, and an optical module operatively positioned relative to the sample processing device and configured to determine whether a selected volume of material is present in the detection chamber of the sample processing device. The method can include rotating the sample processing device about an axis of rotation, and determining whether a selected volume of material is present in the detection chamber, while rotating the sample processing device. In some embodiments, determining whether a selected volume of material is present can be performed by optically interrogating the detection chamber for an optical property of the material.

  • Patent number: 8931331
    Abstract: A system and method for volumetric metering on a sample processing device. The system can include a metering reservoir, and a waste reservoir positioned in fluid communication with a first end of the metering reservoir to catch excess liquid from the metering reservoir that exceeds a selected volume. The system can further include a capillary valve in fluid communication with the second end of the metering reservoir to inhibit liquid from exiting the metering reservoir until desired. The method can include metering the liquid by rotating the sample processing device to exert a first force on the liquid that is insufficient to move the liquid into the capillary valve, and rotating the sample processing device to exert a second force on the liquid that is greater than the first force to move the metered volume of the liquid to the process chamber via the capillary valve.
