11105840 · 2021-08-31 · ·

Systems, methods, and devices for monitoring operation of industrial equipment are disclosed. In one embodiment, a monitoring system is provided that includes a passive backplane and one more functional circuits that can couple to the backplane. Each of the functional circuits that are coupled to the backplane can have access to all data that is delivered to the backplane. Therefore, resources (e.g., computing power, or other functionality) from each functional circuits can be shared by all active functional circuits that are coupled to the backplane. Because resources from each of the functional circuits can be shared, and because the functional circuits can be detachably coupled to the backplane, performance of the monitoring systems can be tailored to specific applications. For example, processing power can be increased by coupling additional processing circuits to the backplane.

Reconstruction of surfaces for additive manufacturing
10974460 · 2021-04-13 · ·

Tracking of measured depth with intervening depositing of one or more layers provides a way of improving the accuracy of surface reconstruction. For example, knowledge of the desired or expected thickness of each layer, in combination with the scan data is combined to yield higher accuracy than is available from scan data of a single scan alone. One application of such an accurate surface reconstruction is in a feedback arrangement in which the desired thickness of one or more subsequent layers to be deposited after scanning is determined from the estimate of the surface depth and a model of the object that is being fabricated, and by increasing accuracy of the surface depth estimate, the precision of the fabrication of the object may be increased.

Method and system for personalizing a vessel stent

For personalizing a vessel stent, images associated with a subject generated by various imaging modalities are aggregated. The images are then processed for identifying Regions of Interest (ROIs) and various parameters associated with the ROIs. Further, a model and a composition of the vessel stent to be administered to the subject to alleviate the condition in the vessel are computed. Thereafter, the model is verified for compatibility using information derived from patient stratification parameters. Upon successful verification of the model, a format of the model is generated that can be used directly for fabricating the vessel stent using additive manufacturing processes known in the art.
