Abstract: A method of manufacturing large lens arrays from glass includes heating glass to take a form of a glass sheet of viscous liquid glass floating on liquid metal. Large lens arrays are made by the method and devices and systems are used for making the large lens arrays. The glass sheet has a lower surface in contact with the liquid metal and an upper surface on an opposite side of the glass sheet away from the liquid metal. The method applies a gas flow on the upper surface of the glass sheet to cause the upper surface of the glass sheet to form a pattern of convex lenses in response to local variations in a pressure profile of the gas flow; and cooling the glass sheet to solidify into a rigid, patterned glass sheet.

Abstract: Systems and methods described herein can non-destructively determine current produce quality. An evaluation system can, at a first time, receive image data of produce and identify a type of the produce using machine learning techniques. The produce can be sent to an end-consumer retail environment. A quality assessment system can, at a second time, receive, from a user device in the retail environment, a request for a current quality of a particular produce that includes scanned data of that produce. The quality assessment system can identify that produce, retrieve, from a data store, machine learning trained models for identifying quality features of that produce, determine, based on applying the models to the scanned data, a current quality of that produce, and transmit, to the user device, the current quality. The produce's price can also be dynamically adjusted based on the current quality of that produce.
