Publication number: 20240134969Abstract: Additive manufacturing's reliance on embedded computing renders it vulnerable to tampering through cyber-attacks. Sensor instrumentation of additive manufacturing devices allows for rigorous process and security monitoring, but also results in a massive volume of noisy data for each run. As such, in-situ, near-real-time anomaly detection is challenging. A probabilistic-model-based approach addresses this challenge.Type: ApplicationFiled: October 18, 2023Publication date: April 25, 2024Inventors: Joel A. Dawson, Srikanth B. Yoginath, Michael D. Iannacone, Varisara Tansakul, Ali Passian, Milton N. Ericson, Gavin B. Long, Robert C. Jordan, Joel M. Asiamah

Patent number: 11855697Abstract: A system senses analytes through one or more sensors that detect or measure a physical characteristic. The one or more sensor generate a spectroscopic-data signal corresponding to the detection. An edge device communicatively couples the one or more sensors that communicatively couples a wide-area network coupling a cloud service. The edge device includes a data acquisition device that receives spectroscopic data signals from the one or more sensor and a processor that processes the spectroscopic-data signals to identify an analyte. The edge device also includes a transceiver that transmits data identifying the analytes to the cloud service.Type: GrantFiled: July 21, 2021Date of Patent: December 26, 2023Assignee: UT-Battelle, LLCInventor: Ali Passian

Patent number: 11074345Abstract: A system and method (referred to as the system) detect infectious code. The system injects a repetitive software code that causes malware in a monitored device to render a detectable direct current power consumption profile. A guide wave generator generates a guide wave signal that establishes an observational window that is applied to data that represent a direct current source power consumption of the monitored device. An extraction device extracts a portion of the data that represent the direct current source power consumption of the monitored device. A deviation engine identifies the malware on the monitored device without processing data associated with a prior identification of the malware or identifying a source of the malware or identifying a location of the malware on the monitored device.Type: GrantFiled: May 30, 2019Date of Patent: July 27, 2021Assignee: UT-BATTELLE, LLCInventors: Joel Dawson, Ali Passian

Patent number: 10436813Abstract: A Surface Plasmon Scanning-Tunneling Chemical Mapping (SPSTM) system is disclosed that determines identification characteristics of a target material. An optical beam source launches an optical beam that propagates through a transparent optical element to a material layer to excite surface plasmons of the material layer. An optical probe with a nanometer-sized tip is positioned over a nanometer-sized region of the target material, which is positioned on the material layer, to measure a probe signal associated only with the surface plasmons that tunnel from the material layer through the nanometer-sized region of the target material and collected by the optical probe. An optical property analyzer is configured to determine at least one optical property associated with the nanometer-sized region based on the probe signal associated with the surface plasmons collected by the optical probe.Type: GrantFiled: May 9, 2018Date of Patent: October 8, 2019Assignee: Institute for Electronics and Information Technology in Tianjin Tsinghua UniversityInventors: Thomas L.

Publication number: 20110231966Abstract: A method for determining chemical characteristics of a sample, the method including directly applying a first acoustic wave at a first frequency to a probe and applying, independent of the directly applying the first acoustic wave, a second acoustic wave at a second frequency to the sample, wherein the first frequency is different than the second frequency and the first acoustic wave and the second acoustic wave are simultaneously applied to the probe and the sample, respectively, and form a coupling. The method further including applying electromagnetic energy to the sample, wherein the electromagnetic energy is absorbed by the sample causing a change in phase of the second acoustic wave. The method further including detecting an effect of the coupling and determining a spectrum of the sample based on the detecting.Type: ApplicationFiled: March 17, 2010Publication date: September 22, 2011Inventors: Ali Passian, Laurene Tetard, Thomas George Thundat, Brian Henry Davison, Martin Keller

Patent number: 7939811Abstract: Low energy light illumination and either a doped semiconductor surface or a surface-plasmon supporting surface are used in combination for manipulating a fluid on the surface in the absence of any applied electric fields or flow channels. Precise control of fluid flow is achieved by applying focused or tightly collimated low energy light to the surface-fluid interface. In the first embodiment, with an appropriate dopant level in the semiconductor substrate, optically excited charge carriers are made to move to the surface when illuminated. In a second embodiment, with a thin-film noble metal surface on a dispersive substrate, optically excited surface plasmons are created for fluid manipulation. This electrode-less optical control of the Marangoni effect provides re-configurable manipulations of fluid flow, thereby paving the way for reprogrammable microfluidic devices.Type: GrantFiled: July 16, 2007Date of Patent: May 10, 2011Assignee: UT-Battelle, LLCInventors: Thomas G Thundat, Ali Passian, Rubye H Farahi
