Publication number: 20200085073Abstract: Food products and systems and methods for their production involve microfiltration (“MF”) of fluid skim to form a MF retentate, combining the MF retentate with cream and subjecting the combination to ultrafiltration (“UF”) to form a UF retentate. Prior to UF, the composition is formed of non-acidified components. Following UF, the UF retentate is acidified and forms a food product including a high solids content. The solids content may be further increased using evaporation. The resulting cheese or cheese base contains a lower whey protein ratio in a fat:casein:whey protein ratio compared to systems and methods that do not employ MF.Type: ApplicationFiled: November 22, 2019Publication date: March 19, 2020Inventors: Thomas Alexander Glenn, III, Clint Garoutte, Kang Hu, Jason Thompson, Orlando Maldonado

Patent number: 10155369Abstract: The present disclosure relates to a method for debonding a pair of bonded substrates. In the method, a debonding apparatus is provided comprising a wafer chuck, a flex wafer assembly, and a set of separating blades. The pair of bonded substrates is placed upon the wafer chuck so that a first substrate of the bonded substrate pair is in contact with a chuck top surface. The flex wafer assembly is placed above the bonded substrate pair so that its first surface is in contact with an upper surface of a second substrate of the bonded substrate pair. A pair of separating blades having different thicknesses is inserted between the first and second substrates from edges of the pair of bonded substrates diametrically opposite to each other while the second substrate is concurrently pulled upward until the flex wafer assembly flexes the second substrate from the first substrate.

Patent number: 10104731Abstract: A dimmable driver for an LED light fixture allows multiple types of dimmers to be used with the light fixture. The dimmable driver may be disconnected from one type of dimmer and subsequently connected to another type of dimmer without having to replace or otherwise adjust the driver for each dimmer. Multiple types of dimmers may be connected to dimmable driver at the same time and the dimmable driver may use dimming signals from one or several of these dimmers. In some embodiments, the dimmable driver is configured to accommodate a step dimmer, a 0-10 V dimmer, and a phase-cut dimmer. Other dimmers and dimming protocols may be accommodated by the dimmable driver in alternative embodiments. Such an arrangement maximizes flexibility for lighting specifiers, contractors, and distributors while minimizing potential errors, costs, delays, and obsolete inventory.Type: GrantFiled: December 8, 2015Date of Patent: October 16, 2018Assignee: ABL IP Holding LLCInventors: Feng-Kang Hu, Hangyang Wang, Feng Chen, Towfiq Chowdhury, Charles J.
