  • Patent number: 11806711
    Abstract: Various fluidic structures are described that may be implemented between two portions of material, at least one of which may be made of a flexible but inelastic material, such as Mylar. Such fluidic circuits may be configured such that applying a clamping pressure zone to such fluidic circuits and then moving the clamping pressure zone along the fluidic circuit and along a particular axis may cause the fluidic circuit to operate in a particular manner, thereby driving fluids contained within the fluidic circuit around the fluidic circuit according to a desired flow sequence.

  • Patent number: 11533392
    Abstract: Provided is a solid-state illumination system for use in a microscopy system utilizing a light sensor of a mobile phone camera module. The system includes a bright-field illumination source with an array of light-emitting diodes (LEDs). The array of LEDs is configured to produce transmission light within a range of view of the light sensor of the mobile phone camera module. The system also includes a dark-field illumination source including a ring of LEDs. The ring of LEDs is configured to produce light outside of the range of collection of the camera module lens. The system also includes a diffuser configured to diffuse the transmission light and a diffusive black material coupled to the diffuser. The diffusive black material is configured to pass through at least some of the transmission light while blocking reflections of the scattering light.
