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: 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.
