  • Publication number: 20260216456
    Abstract: A portable airway clearance system utilizing adaptive suction control, modular architecture, and intelligent patient profiling is disclosed. The system includes a suction mechanism configured to generate negative pressure, an airflow pathway, and control circuitry configured to modulate suction according to a time-varying suction profile. The system supports multiple suction generation mechanisms, including diaphragm pumps and propeller systems, and utilizes nonlinear waveform modulation for effective and safe airway obstruction removal. In certain embodiments, sensor inputs are used to dynamically adjust or terminate suction, and patient classification is used to constrain operation within predefined safety limits.

  • Publication number: 20260137270
    Abstract: The invention relates to a method and an apparatus, termed the “CapsuleProbe”, adapted from the capsule endoscopy technology for cervical and/or vaginal examinations. The CapsuleProbe features a capsule endoscope enclosed in an elongated cylindrical housing designed for easy insertion into the vaginal canal. This device provides a minimally invasive and user-friendly option for patients as well as enhanced visualization of the cervix for healthcare providers. With its substantially minimized dimensions comparing to existing medical devices for cervical and/or vaginal examinations, this device improves feasibility, accessibility, and patient comfort significantly, particularly for postmenopausal women and those suffering from vaginal atrophy, by reducing or eliminating procedure-related pain and/or bleeding from the tearing of vaginal walls caused by existing medical devices used for cervical and/or vaginal examinations.

  • Patent number: 5872865
    Abstract: A computer system and computer implemented method automatically classify video sequences into categories. A set of categories is defined either manually through the association of selected video sequences with user supplied category designations, or automatically through segregation of a set of video sequences into groups of similar sequences. Input video sequences are then classified by either pixel decomposition or primitive attribute decomposition; the former analyzing each image on a pixel basis, the latter employing extracted image information. Categories can be trained as new video sequences are input into the system, or new categories can be created to accommodate such new sequences that are dissimilar from existing categories.

  • Patent number: 5805733
    Abstract: A method and system summarizes scenes in a video sequence by detecting scene changes, and then comparing scenes in a moving window to determine their similarity. Similar scenes are consolidated and represented by a representative frame, a number of which are displayed to a user. Scene changes are detected by comparing average color histograms for each scene, motion compensated pixel differences or motion compensated edge maps, or a combination of these methods. Scenes in the video sequence are selected for summarizing according to their normalized time duration. Of the selected scenes, similar or related scenes are determined by comparing the average color histograms of each pair of scenes in a moving window, using a standard population error measure, such as a Chi-squared test. For each set of related scenes, a representative frame is taken, either as the medial frame from the entire time duration of the related scenes or as the first frame of the medial scene in the set.

  • Patent number: 5802361
    Abstract: A system and method for searching images includes a low level analyzer for processing image data in a plurality of images into side information files, the image data of each side information file pertaining to a particular statistical or perceptual abstraction of the images, such as motion, color, texture, segments, and the like. A user interface allows a user to graphically construct a search inquiry with icons representing image attributes corresponding to the image data in the side information files. A search inquiry may include complex boolean expressions, and custom image attributes may be created to represent useful search inquiries. The image attributes of a search inquiry may also be ranked. A high level analyzer parses a search inquiry to determine the image attributes contained therein, and analyzes the image data of the side information files to determine a similarity measure for each image with respect to the search inquiry.
