  • Patent number: 11813024
    Abstract: System and Method pertaining to the modification and integration of an existing consumer digital camera, for example, with an optical imaging module to enable point and shoot fundus photography of the eye. The auto-focus macro capability of existing consumer cameras is adapted to photograph the retina over an extended diopter range, eliminating the need for manual diopter focus adjustment. The thru-the-lens (TTL) auto-exposure flash capability of existing consumer cameras is adapted to photograph the retina with automatic flash exposure eliminating the need for manual flash adjustment. The consumer camera imaging sensor and flash are modified to allow the camera sensor to perform both non-mydriatic focusing of the retina using infrared illumination and standard color flash photography of the retina without the need for additional imaging sensors or mechanical filters.

  • Publication number: 20230144498
    Abstract: Various aspects related to methods, systems, and computer readable media for simulating and controlling a physical system, such as, for example, a greenhouse. A computer-implemented method can include forming a computational graph, wherein a structure of the computational graph is based on one or more physical processes in the physical system, receiving, from one or more sensors, measured values of one or more observed states of the physical system, setting initial values of one or more unobserved states of the physical system, receiving values of one or more control inputs a for the physical system, and iteratively simulating the physical system on a computer using x, y and a as simulation inputs to the computational graph.

  • Patent number: 9986910
    Abstract: Apparatus and techniques can include using one or more of a portable or fixed optical system to obtain images of a desired anatomical target, such as the fundus region of a human eye. The optical system can include one or more of a laser-based focusing target, a laser-based fixation target, or a removable or adjustable alignment assembly. Such an alignment assembly can provide or allow user alignment based on using anatomical landmarks other than the fundus being imaged. One or more of the apparatus or techniques can be implemented in an optical assembly included as a portion hand-held fundus camera, such as including or using a consumer or commercial digital camera to capture an image.
