  • Patent number: 11301746
    Abstract: A system for providing a persona-driven and artificially-intelligent avatar is disclosed. The avatar may be utilized to represent an artificially-intelligent virtual assistant that may perform actions on behalf of a user, such as actions related to an investment strategy for the user. Notably, the avatar may influence artificial intelligence algorithms supporting the functionality of the virtual assistant via quantifiable traits of a persona of the avatar. In particular, the quantifiable traits of the persona of the avatar may be utilized to range bound the controlling parameters of the algorithms such that the virtual assistant represented by the avatar performs actions that conform to the ranged-bounded controlling parameters. Metrics corresponding to the performance of the virtual assistant may be tracked, and the system may modify parameters of the virtual assistant based on the metrics so as to adjust future actions performed by the virtual assistant for the user.

  • Publication number: 20220047161
    Abstract: A breast diffusion optical tomography (DOT) device includes a light source, a detector, a mechanical driver and a contour acquisitor without using optical fiber and reduce the system complexity. The light source includes M1 number of multi-wavelength near-infrared light emitters for a continuous-wave mode and M2 number of laser diodes of different wavelengths for a frequency-domain mode. The detector includes N1 number of silicon photomultipliers for detecting near-infrared light in the continuous-wave mode and N2 number of silicon photomultipliers for detecting near-infrared light in the frequency-domain mode. The mechanical driver adjusts a distance between the light source and the detector. The contour acquisitor obtains the geometry of a patient's breast for reconstruction. The DOT device uses amplitude and phase information obtained in the frequency-domain mode to estimate initial optical parameters of tissues and then apply for reconstruction in the continuous-wave mode.
