  • Patent number: 11009464
    Abstract: Methods, apparatuses, and computer program products are provided where fluid, such as a blood sample, is entered into a microfluidic channel in a microchip where the microfluidic channel possesses a micro/nanopillar array for sorting molecules by size. When the fluid passes through the micro/nanopillar array it is separated into particles of interest or particles not of interest or both. When particles of interest are lit by a light source via a first waveguide in the microchip connecting the light source to the microfluidic channel, then lighted particles of interest can be detected by an optical detector via a second waveguide in the microchip connecting the optical detector to the microfluidic channel. The information from the optical detector can be analyzed further by connecting the microchip to a mobile computing device with its own processing abilities or abilities via the internet or cloud.

  • Patent number: 10898897
    Abstract: Techniques relate to forming a sorting device. A mesh is formed on top of a substrate. Metal assisted chemical etching is performed to remove substrate material of the substrate at locations of the mesh. Pillars are formed in the substrate by removal of the substrate material. The mesh is removed to leave the pillars in a nanopillar array. The pillars in the nanopillar array are designed with a spacing to sort particles of different sizes such that the particles at or above a predetermined dimension are sorted in a first direction and the particles below the predetermined dimension are sorted in a second direction.

  • Publication number: 20200250584
    Abstract: The present invention provides a modeling method for a smart prognostics and health management system. The method comprises a new tree establishing step, a dual-branch modeling step, and a model adaptive optimization step. As monitoring data increases, a golden model can be selected as a benchmark for optimization decision from prediction hypothesis models constructed by the dual-branch modeling step. This benchmark is used for next prediction. A prediction result of the system is caused to meet an expected target value. The present invention provides a computer program product for the smart prognostics and health management system at the same time. The above-described modeling method for the smart prognostics and health management system is completed when the computer program product is executed.
