Patent number: 12321326Abstract: Processing circuitry is configured to obtain a data structure that defines a plurality of conversions of data between pairs of fields; perform a search to identify a plurality of paths from a source node of the data structure to a destination node of the data structure, wherein the source node corresponds to a first field of the fields and the destination node corresponds to a second field of the fields; convert, for each path of the plurality of paths, transforms represented by corresponding edges of the path to a sequence of transforms that conform to a solver format; process the sequence of transforms for each path to determine whether all paths of the plurality of paths are equivalent up to an equivalence relation; and output an indication of whether all paths of the plurality of paths are equivalent up to an equivalence relation.Type: GrantFiled: December 17, 2021Date of Patent: June 3, 2025Assignee: SRI InternationalInventors: Bruno Dutertre, Susmit Jha, Huascar Sanchez, Patrick Lincoln, Eric M. Pearson, Richard Dean, Ian A. Mason

Patent number: 8410678Abstract: Described is a micro-fabricated charged particle emission device including a substrate and a plurality of charged particle emission sites formed in the substrate. A path extends between each emission site and a source of liquid metal. Each path is coated with a wetting layer of non-oxidizing metal for wetting the liquid metal. Exemplary non-oxidizing metals that may be used to make the wetting layer include gold and platinum. The wetting layer is sufficiently thin such that some liquid metal is able to flow to each emission site despite any chemical interaction between the liquid metal and the non-oxidizing metal of the wetting layer.Type: GrantFiled: February 28, 2012Date of Patent: April 2, 2013Assignee: SRI InternationalInventors: Christopher E. Holland, Paul R. Schwoebel, Charles A. Spindt, Eric M. Pearson, Victor M. Aguero

Patent number: 6879162Abstract: Described are a method and system for dispensing a fluid. A fluid-dispensing device includes a substrate and a plurality of nozzles formed in the substrate. Each nozzle has an open-ended tip and a fluid-conducting channel between the tip and a source of fluid. A non-conducting spacer is on the substrate and electrically isolates a gate electrode from the substrate. The gate electrode is located adjacent to the tip of at least one of the nozzles to effect dispensing of the fluid in that nozzle in response to a voltage applied between the gate electrode and the nozzle or fluid in the nozzle. In one embodiment, the gate electrode includes a plurality of individually addressable gate electrodes used for selectively actuating nozzles.Type: GrantFiled: October 31, 2002Date of Patent: April 12, 2005Assignee: SRI InternationalInventors: Victor M. Aguero, Elizabeth J. Brackmann, Jose P. Joseph, Christopher E. Holland, Charles A. Spindt, Paul R. Schwoebel, Eric M. Pearson

Patent number: 5381362Abstract: A high-speed, high-throughput matched optical filter for processing data that allows for rapid reprogramming to change the reference signal or signals. A coherent time-domain optical memory system includes a coherent time-domain optical storage material (18) and a laser (16) for providing pulses of optical radiation in coherent time-domain optical storage relation with the storage material. One or more reference signals are first stored in the material by modulating one or more of the laser pulses with the reference signals and writing these pulses on the storage material (18) in close succession with their associated write pulses as is customary in coherent time-domain optical memories. The reference signals are phase encoded before they are stored. Another laser pulse modulated with the signal to be processed is then applied to the storage material. The echo signal induced by this signal pulse takes the form of the correlation of the reference pulse with the signal pulse.Type: GrantFiled: July 30, 1993Date of Patent: January 10, 1995Assignee: SRI InternationalInventors: Xiao An Shen, Yu Sheng Bai, Eric M.
