Abstract: The present invention relates to the field of medical health monitoring. Disclosed in the present invention is an on-skin sensing system for detecting blood flow status in a postoperative flap and reconstructed limb, the system including a front-end status detection module and a back-end signal processing and outputting module. The front-end status detection module acquires, in real time, blood oxygen saturation and temperature statuses of postoperative flaps and reconstructed limbs. The front-end status detection module uses a flexible packaging layer to package a printed circuit board, and after the surface of the flexible package layer is chemically treated, a pre-polymerized hydrogel solution is injected to carry out cross-linking to obtain a hydrogel adhesive layer, thereby ensuring long-time close attachment to the skin while avoiding bacterial infection on the surface of the skin. The back-end signal processing and outputting module processes blood oxygen saturation and temperature data, and transmits the data to a mobile terminal in real time. The present invention enables on-line monitoring of the blood flow health status of postoperative flaps and reconstructed limbs. When the blood oxygen saturation of the human body is below a normal value or when temperature and pulse signals are abnormal, the mobile terminal will trigger an alarm function, promptly alerting medical staff and the patient.

Abstract: A method and a device for non-contact determination of temporal color and/or intensity variations in objects in a scene. Monoscopic overview images of the scene are detected with first and second overview cameras from two different viewing directions, and calculated to form a stereoscopic overview map. A two-dimensional detail image is detected by a detail camera from a third viewing direction and is projected on the overview map. Measurement surfaces in the scene are selected based on criteria which are predetermined depending on parameters on which conclusions are to be drawn from the color variations and/or intensity variations. Light emitted by the measurement surfaces is detected in a spatially-resolved and wavelength-resolved manner in a continuously-captured series of measurement images in a predetermined spectral range. The measurement surfaces are analyzed in the measurement images with respect to temporal variation of the intensity and/or color of the light, and the results displayed.

Abstract: System and method that utilize windowing for efficient capturing of facial landmarks include an inward-facing head-mounted camera that captures images of a region on a user's face utilizing a sensor supporting changing of its region of interest (ROI). The system also includes a computer that detects, based on the images, a type of facial expression expressed by the user, which belongs to a group comprising first and second facial expressions. Responsive to detecting that the user expresses the first facial expression, the computer reads from the camera a first ROI that covers a first subset of facial landmarks relevant to the first facial expression. Responsive to detecting that the user expresses the second facial expression, the computer reads from the camera a second ROI that covers a second subset of facial landmarks relevant to the second facial expression, with the first and second ROIs being different.

Abstract: A near-field sensor method and device for obtaining biomedical information is disclosed. A transmission-line aperture arrangement configured to guide electromagnetic waves and emit near-field fringing energy, is placed near the skin. The transmission line is excited at a narrow-band Gigahertz frequency. The near-field fringing energy emitted by the sensor device penetrates at least partially into the skin and underlying blood vessels, and this energy is partially absorbed and partially phase shifted in a time varying manner according to the changes in tissue physiology. The status of the sensor device is monitored over a plurality of time intervals, and changes in both the phase and the amplitude of the signals passing though the transmission line are used to determine biomedical information such as heart rates, PTT, blood pressure, and glucose levels. Various transmission-line configurations, and various reference transmission-line methods to reduce low-frequency noise, are also discussed.
