Patent number: 11340200Abstract: A spray-capillary device is configured to process ultra low-volume samples. The spray-capillary device includes a spray capillary that includes an inlet end and a discharge end. The spray capillary includes a porous section at the discharge end. A downstream connector provides an interface between the porous section of the spray capillary, a conductive fluid, and a high voltage electrical source. The application of voltage to the downstream connector causes electrospray ionization, which can be used to draw ultra law volume samples into the inlet end. A gas injection assembly can be used to increase the pressure on the inlet end of the spray capillary to encourage movement of the sample through the spray capillary. The spray-capillary device is well suited for providing ultra low samples to a mass spectrometer detection device.Type: GrantFiled: March 8, 2021Date of Patent: May 24, 2022Assignee: The Board of Regents of the University of OklahomaInventors: Si Wu, Lushuang Huang, Zhe Wang

Patent number: 11313959Abstract: Methods, systems and non-transitory computer readable mediums for processing radar signals to recover signals inside a blind region are disclosed. A transmission signal is transmitted from a radar system. The radar system receives a return signal. The return signal includes a first portion of the transmission signal leaked during transmission and a second portion reflected from an object within the blind region. The return signal is partially decoded by zeroing out the first portion of the transmission signal to form a modified return signal. Pulse compression is performed over the modified return signal to form a compressed return signal. The compressed return signal is processed to calculate moment products. The moment products are calibrated with a calibration factor, wherein the calibration factor is multiplied against only calculated moment products of range gates which have been partially decoded.Type: GrantFiled: January 29, 2020Date of Patent: April 26, 2022Assignee: The Board of Regents of the University of OklahomaInventors: Cesar M.
