  • Patent number: 11099551
    Abstract: Example implementations described herein involve a system for maintenance predictions generated using a single deep learning architecture. The example implementations can involve managing a single deep learning architecture for three modes including a failure prediction mode, a remaining useful life (RUL) mode, and a unified mode. Each mode is associated with an objective function and a transformation function. The single deep learning architecture is applied to learn parameters for an objective function through execution of a transformation function associated with a selected mode using historical data. The learned parameters of the single deep learning architecture can be applied with streaming data from with the equipment to generate a maintenance prediction for the equipment.

  • Publication number: 20180341876
    Abstract: Equipment uptime is getting increasingly important across different industries which seek for new ways of increasing equipment availability. Detecting faults in the system by condition based maintenance (CBM) is not enough, because at the time of fault occurrence, the spare parts might not available or the needed resources (maintainers) are busy. Therefore, prediction failures and estimation of remaining useful life can be necessary. Moreover, not only predictions but also uncertainty in the predictions is critical for decision making. Example implementations described herein are directed to tuning parameters of deep learning network architecture by developing a mechanism to optimize for accuracy and uncertainty simultaneously, thereby achieving better asset availability, maintenance planning and decision making.

  • Patent number: 9261496
    Abstract: Provided herein are microfluidic devices that can be used as a 3D bioassay, e.g., for drug screening, personalized medicine, tissue engineering, wound healing, and other applications. The device has a series of channels {e.g., small fluid channels) in a small polymer block wherein one or more of the channels can be filled with a biologically relevant gel, such as collagen, which is held in place by posts. As shown herein, when the device is plated with cells such as endothelial cells, new blood vessels grow in the gel, which is thick enough for the cells to grow in three dimensions. Other channels, e.g., fluid channels, allow drugs or biological material to be exposed to the 3D cell growth. Cells, such as endothelial cells, can be cultured and observed as they grow on the surface of a 3D gel scaffold, where e.g., rates of angiogenesis can be measured, as well as intervascularization and extravascularization of cancerous cells.
