Patent number: 11103702Abstract: The present invention provides a method implementing a speech strategy based on zero crossing behavior of speech time waveforms; the zero crossing containing both spectral and temporal speech information. This method uses temporal information of speech to activate electrodes instead of spectral information; maps temporal segment durations to spatial durations along the basilar membrane inside the cochlea; and provides instantaneous, continuous information about speech to electrodes that stimulate the auditory nerve. Timing of oval window mechanical motion is represented by zero crossings which are used to activate electrodes implanted inside the cochlea. Motion of the tympanic membrane, and the oval and round windows, follow the speech signal temporal waveform. Positive segments of the temporal waveform cause inward displacement of the oval membrane from its stationary position and negative segments causes outward retraction of the membranes.Type: GrantFiled: August 24, 2018Date of Patent: August 31, 2021Assignee: University of Central OklahomaInventor: Mohamed G. Bingabr

Patent number: 9987089Abstract: This invention relates to a device and a method for monitoring and optimizing photothermal therapy, using a high-power continuous-wave laser beam and a pulsed laser beam, both transmitted through a single soft, multi-mode optical fiber with a diffuse active tip, to interstitially irradiate the target tissue at the same time. The continuous-wave laser light induces photothermal effect and increases tissue temperature and the pulsed laser light produces a photoacoustic signal.

Patent number: 9809906Abstract: The present invention implements a set of grooves/ridges created on Ti at the circumferential direction to increase surface area of implant in contact with bone. These grooves/ridges protect nanofiber matrix (NFM) made with Polycaprolactone (PCL) electrospun nanofiber (ENF) and collagen at the groove from physiological loading. Controlled fabrication of a ridge made with titanium nitride (TiN) around the circumference of Ti is provided using a plasma nitride deposition technique. PCL ENF may be deposited along the sub-micrometer grooves using the electrospin setup disclosed. The method provides for fabrication of microgroove on Ti using machining or TiN deposition and filling the microgrooves with the NFM. This method has proven through experimentation to be successful in increasing in vivo mechanical stability and promoting osseointegration on Ti implants. The immobilization of MgO NP and FN with the PCL-CG NFM on microgrooved Ti as provided in the invention optimizes biological performances of Ti.Type: GrantFiled: March 23, 2017Date of Patent: November 7, 2017Assignee: University of Central OklahomaInventors: Morshed Khandaker, Shahram Riahinezhad
