Publication number: 20210282736Abstract: A method for determining respiratory rate from an audio respiratory signal comprising capturing the audio respiratory signal generated by a subject using a microphone. The method also comprises segmenting the audio respiratory signal into a plurality of overlapping frames. For each frame of the plurality of overlapping frames, the method comprises extracting a signal envelope, computing an auto-correlation function, computing an FFT spectrum from the auto-correlation function and computing a respiratory rate of the subject using the FFT spectrum.Type: ApplicationFiled: April 28, 2021Publication date: September 16, 2021Inventors: Charalampos-Christos Stamatopoulos, Francis Patrick O'Neill, Jason Eichenholz

Patent number: 6897999Abstract: Two, three dimensional color displays having uniform dispersion of red, green and blue visible light emitting micron particles. Pumping at approximately 976 nm can generate green and red colors having an approximately 4% limit efficiency. One source can generate three colors with approximately limit efficiency. Modulators, scanners and lens can move and focus laser beams to different pixels forming two dimensional color images. Displays can be formed from near infrared source beams that are simultaneously split and modulated with micro electro mechanical systems, spatial light modulators, liquid crystal displays, digital micromirrors, digital light projectors, grating light valves, liquid crystal silicon devices, polysilicon LCDs, electron beam written SLMs, and electrically switchable bragg gratings. Pixels containing: Yb,Tm:YLF can emit blue light, Yb,Er(NYF) can emit green light, and Yb,Er:KYF and Yb,Ef:YF3 can emit red light.Type: GrantFiled: December 26, 2002Date of Patent: May 24, 2005Assignee: The Research Foundation of the University of Central FloridaInventors: Michael Bass, Jason Eichenholz, Alexandra Rapaport

Patent number: 6327282Abstract: A tunable, solid state laser device with both visible and infrared laser emission is developed with a trivalent ytterbium-doped yttrium calcium oxyborate crystal as the host crystal. The Yb:YCOB crystal generates an infrared fundamental light over a wide bandwidth, from approximately 980 nanometers (nm) to approximately 1100 nm. The bandwidth generated by the Yb:YCOB crystal is approximately 100 nm wide and supports the generation of pulsed infrared light or when self-frequency doubled provides a compact, efficient, source of tunable, visible, blue or green laser light in wavelengths of approximately 490 nm to approximately 550 nm.Type: GrantFiled: December 27, 2000Date of Patent: December 4, 2001Assignee: University of Central FloridaInventors: Dennis Allen Hammons, Qing Ye, Jason Eichenholz, Bruce H. T. Chai, Martin Richardson

Patent number: 6301275Abstract: Neodymium-doped yttrium calcium oxyborate (Nd:YCOB) is the single active gain element for a solid-state laser device capable of achieving both lasing and self-frequency doubling optical effects. A pumping source for optically pumping Nd:YCOB can generate a laser light output of approximately 400 mW at approximately 1060 nm wavelength and a self-frequency doubled output of approximately 60 mW at approximately 530 nm wavelength. Thus, a laser device can be designed that is compact, less expensive and a high-powered source of visible, green laser light.Type: GrantFiled: December 27, 2000Date of Patent: October 9, 2001Assignee: University of Central FloridaInventors: Jason Eichenholz, Qing Ye, Dennis Allen Hammons, Bruce H.
