Patent number: 11774457Abstract: Protein biomarkers may be used to rapidly and accurately diagnose stroke. Biomarkers may be utilized in a rapid and inexpensive test that could be used at the bedside or ambulatory setting to definitively indicate the presence or absence of stroke and its severity. Such a test would quickly stratify patients in need of immediate stroke treatment from those who are not having a stroke. The test may aid emergency personnel in the decision for the most appropriate treatment plan and treatment location, thereby minimizing morbidity and mortality of stroke patients.Type: GrantFiled: July 9, 2019Date of Patent: October 3, 2023Assignee: Wright State UniversityInventors: James Edwin Olson, April Daubenspeck, David Cool, Bryan Ludwig

Patent number: 10575787Abstract: A hydration sensor is provided that includes a circulator having a plurality of ports, an amplitude-modulated coherent source connected to a first port of the circulator, a rectifier or other power sensor connected to a second port of the circulator followed by an RF baseband low-noise amplifier, a coupling structure connected to the third port of the circulator, and a demodulator connected to the output of the rectifier. The hydration sensor can include an RF low noise amplifier between the circulator and rectifier, and/or a second amplitude modulator between the circulator and the coupling structure. The coupling structure can be either a guided-wave near-field structure or an interfacial capacitive or inductive element. In the former case, the hydration is determined by measuring the reflectivity of the guided-wave radiation, and in the latter case it is determined by measuring the change of reflectivity (through change of impedance) of the interfacial element.Type: GrantFiled: April 17, 2017Date of Patent: March 3, 2020Assignee: Wright State UniversityInventors: Elliott R.

Patent number: 10169293Abstract: A method for processing a digital signal comprises identifying a desired frequency and/or phase response that is represented in a frequency domain representation. A fractional order control system that models the desired frequency and/or phase response is constructed by assembling a first filter component from a filter component library and a second filter component from the filter component library. At least one filter component of the filter component library is defined by a Laplace function that includes a non-integer control order having a variable fractional scaling exponent and a value for the non-integer, variable fractional scaling exponent of the second filter component is based on a value of the non-integer, variable fractional scaling exponent of the first filter component. An input in the digital frequency domain is received and processed based upon the fractional order control system to generate a digital output. The output is then conveyed to a user.Type: GrantFiled: August 21, 2017Date of Patent: January 1, 2019Assignee: WRIGHT STATE UNIVERSITYInventor: Jeffrey R. Smigelski

Patent number: 10164609Abstract: A digital signal synthesizer for generating a frequency and/or phase modified digital signal output comprises an input buffer, a transform module, a processing module, and an output buffer. The input buffer receives a digital input that is represented in a frequency domain representation. The transform module stores a fractional order control system that models a desired frequency and/or phase response defined by an assembly of at least one filter component. Each filter component is defined by a Laplace function that is modified to include a non-integer control order having a variable fractional scaling exponent. The processing module multiplies or divides the digital input with the fractional order control system stored in the transform module. Moreover, the output buffer stores a synthesized output of the input, which is modified in the frequency domain, the phase domain, or both according to the desired frequency and/or phase response by the processing module.Type: GrantFiled: February 17, 2017Date of Patent: December 25, 2018Assignee: Wright State UniversityInventor: Jeffrey R.
