  • Patent number: 11448799
    Abstract: A device for altering vergence of light to improve human vision of an electronic display. The change in vergence is received at the pupil of the wearer. The altered light effectively recreates the rays emitted by a pixel such that they reach a presbyopic eye as though they were being viewed at a distance (i.e., the rays are substantially parallel). As such, the emmetropic presbyopic eye produces a sharp image of the electronic display. The device comprises: a refractive element that refracts rays, emitted from a pixel of an electronic display, at a predetermined vergence, wherein the refractive element is located directly adjacent or on the electronic display.

  • Patent number: 11422257
    Abstract: This invention provides an integrated time-of-flight sensor that delivers distance information to a processor associated with the camera assembly and vison system. The distance is processed with the above-described feedback control, to auto-focus the camera assembly's variable lens during runtime operation based on the particular size/shape object(s) within the field of view. The shortest measured distance is used to set the focus distance of the lens. To correct for calibration or drift errors, a further image-based focus optimization can occur around the measured distance and/or based on the measured temperature. The distance information generated by the time-of-flight sensor can be employed to perform other functions. Other functions include self-triggering of image acquisition, object size dimensioning, detection and analysis of object defects and/or gap detection between objects in the field of view and software-controlled range detection to prevent unintentional reading of (e.g.
