Sean Hwang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11712200
    Abstract: A device for detection of tetrahydrocannabinol or THC in a sample includes a sensor including a substrate and a sensor medium on the substrate. The sensor medium includes at least one nanostructure, wherein at least one property of the sensor medium is dependent upon the presence of THC on a surface of the sensor medium. The device further includes electronic circuitry including at least one measurement system in operative connection with the sensor to measure a variable relatable to the at least one property of the sensor medium dependent upon the presence of THC.
    Type: Grant

  • Patent number: 10592636
    Abstract: A system, computer-readable medium, and a method including receiving flight data engine measurements for at least one engine of the specific aircraft asset; receiving flight data aerodynamics measurements for the specific aircraft asset; combining a physics based parametric aerodynamic performance model tuned for the specific aircraft asset using the flight data aerodynamics measurements and a physics based engine model tuned for the specific aircraft asset using the flight data engine measurements; calculating, based on the combined tuned aerodynamic performance model and the tuned engine model, a performance model for the specific aircraft asset as a whole; and storing a record of the calculated performance model for the specific aircraft asset for a future deployment.

  • Publication number: 20180349322
    Abstract: Generation of models in real time embedded systems that approximate non-embedded models while reducing a complexity associated with the non-embedded models is provided herein. A system can comprise a memory coupled to a processor. The memory stores executable components executed by the processor. The executable components can comprise an evaluation manager component that identifies an input parameter of a first model based on a defined output parameter of the first model and a relation manager component that determines one or more relations in the first model. Relations of the one or more relations can comprise an intermediary parameter determined based on the input parameter and the defined output parameter of the first model. Further, the system can comprise a model generator manager component that generates a second model that approximates the first model and includes a replication of the one or more relations of the first model.

  • Patent number: 5011631
    Abstract: This invention relates to a turbo-jet aerator and in particular to one mainly including a motor, a turbo-jet means and a stirring mechanism by means of which when the motor is turned on, the turbine and the stirring mechanism will be rotated and air in the recesses between leaves of the turbine will be sucked in from the outside and ejected out through the outlet of the turbo-jet means and then the air will pass and dissolve into water of a pond.
