Latest Patents

One of Howell's latest patents is titled "Machine learning informed control systems for extrusion printing processes." This invention provides systems and methods for controlling a material extrusion device to extrude a filament of an ink. The extrusion printing control system collects measurements from sensors that represent the internal state of material extrusion processing during the filament's extrusion. Additionally, it captures an image of the filament as it is extruded. The system applies a classifier to the collected image to generate an image-derived state characterizing the filament. Based on both the internal state and the image-derived state, the system estimates a derived state using a model. It then determines control parameters to achieve the desired quality of the filament by minimizing a cost function based on various factors. Finally, the control parameters are provided to the controller of the material extrusion device.

Another significant patent is "Optical authentication of images." This invention outlines systems and methods for generating authentication information for an image using optical computing. When a user photographs an object, the optical authentication system receives light reflected and/or emitted from the object. The system also receives a random key from an authentication server. It converts the received light to plenoptic data and uploads it to the authentication server. Furthermore, the system generates an optical hash of the received light using the random key, converts this optical hash to a digital optical hash, and uploads it to the authentication server. The authentication server then verifies whether the upload time is within a certain threshold from the random key's sending and whether the digital optical hash was generated from the same light as the plenoptic data.
