Ynjiun P. Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220408043
    Abstract: The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

  • Patent number: 11283975
    Abstract: An imaging device includes a housing having a surface that can engage the face of a patient. A cavity is at least partially defined by the surface. An anterior imaging system includes an optical lens barrel positioned inside the cavity, and the optical lens barrel includes a variable focus lens at one end and an image sensor array at an opposite end. One or more illumination LEDs are positioned around the periphery of the optical lens barrel at opposite sides of the variable focus lens, and are configured to illuminate the cavity to capture images of an anterior of the eye.
