Patent number: 10860746Abstract: A system and method is provided for a cryptographic primitive and authentication protocol comprised of micro-cavity resonators at optical wavelengths. A micro-cavity resonator is illuminated with an optical challenge signal and the cavity returns an output response that is dependent on the input signal. Digital signal processing is performed on the output signal to generate a corresponding digital representation. This process is repeated for variations of the input signal with its digital output being stored in a database. A user or object claiming an identity presents a token to the system. The system selects a subset of the available challenge-response pairs and presents the challenges to the token. The system compares the digitized responses with the original responses expected for that token. The system will approve or deny the claimed identity corresponding to the presented token.Type: GrantFiled: April 7, 2017Date of Patent: December 8, 2020Assignee: The Johns Hopkins UniversityInventors: Amy C. Foster, A. Brinton Cooper, III, Mark Foster, Brian C. Grubel

Patent number: 10124962Abstract: A roll-formed steel slat for use in a reciprocating floor slat conveyor system. The roll-formed steel slat is formed in a manner so as to have an upper, load-carrying surface, and a pair of downwardly depending side legs. Each side leg terminates in a foot. One foot is vertically offset from the other to provide a “hold-down” function that prevents the slat from vertically rising as the slat reciprocates back-and-forth.Type: GrantFiled: May 14, 2018Date of Patent: November 13, 2018Assignee: Keith Manufacturing Co.Inventors: Daniel W. Jackson, Randall Mark Foster, Nathan Keeley, Victor Matthews, Scott Delamarter
