Patent number: 11997393Abstract: A method for calculating a current illumination level of a target scene capable of quantitatively evaluating an illumination level in a scene through a camera, and a method for automatically adjusting an illumination level of the target scene capable of automatically performing a constant light control over a scene, and a camera, capable of quantitatively evaluating the illumination level in the scene and a smart illumination control system are provided. The smart illumination control system is capable of quantitatively evaluating the illumination level in the scene and automatically adjusting an illumination brightness, a color temperature, a color or a contrast in the scene to realize a constant control over a light environment. In addition, by setting the illumination level on a setting terminal, an illumination product also performs a light-supplementing automatically for the camera to realize a constant light control over a shooting.Type: GrantFiled: June 8, 2020Date of Patent: May 28, 2024Assignee: ANDON HEALTH CO., LTD.Inventors: Qin Li, Yang Guo, Fei Zhang, Jinjin Li

Patent number: 10698053Abstract: Described here are systems and methods for magnetic resonance imaging (“MRI”) using a sweeping frequency excitation applied during a time-varying magnetic field gradient. As an example, a gradient-modulated offset independent adiabaticity (“GOIA”) approach can be used to modify the pattern of the sweeping frequency excitation. Data are acquired as time domain signals and processed to generate images. As an example, the time domain signals are processed using a correlation between a Fourier transform of the gradient-modulated sweeping frequency excitation and a Fourier transform of the time domain signals.Type: GrantFiled: February 9, 2015Date of Patent: June 30, 2020Assignee: Regents of the University of MinnesotaInventors: Jinjin Zhang, Michael Garwood, Djaudat Idiyatullin, Curt Corum, Naoharu Kobayashi
