  • Patent number: 10299717
    Abstract: Described herein are systems and methods for detecting a stress level of a user. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAM) and a computer. CAM takes thermal measurements of a region on a periorbital area (THROI1) of the user. The computer generates feature values based on THROI1, and utilizes a model to detect the stress level based on the feature values. The model was trained based on: previous THROI1 taken while the user was under elevated stress, and other previous THROI1 taken while the user was not under elevated stress. Some embodiments may utilize additional thermal cameras that take thermal measurements of other regions on the face, which may be utilized to detect the stress level.

  • Patent number: 10136856
    Abstract: A wearable system configured to collect thermal measurements related to respiration. The system includes a frame configured to be worn on a user's head, and at least one non-contact thermal camera (e.g., thermopile or microbolometer based sensor). The thermal camera is small and lightweight, physically coupled to the frame, located close to the user's face, does not occlude any of the user's mouth and nostrils, and is configured to take thermal measurements of: a portion of the right side of the user's upper lip, a portion of the left side of the user's upper lip, and a portion of the user's mouth. The thermal measurements are forwarded to a computer that calculates breathing related parameters, such as breathing rate, an extent to which the breathing was done through the mouth, an extent to which the breathing was done through the nostrils, and ratio between exhaling and inhaling durations.

  • Patent number: 10136852
    Abstract: Described herein are systems and methods for personalized detection of an allergic reaction of a user. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAM) and a computer. CAM takes thermal measurements of a region on the nose (THN) of a user. The computer generates feature values based on THN and utilizes a model to detect an allergic reaction of the user based on the feature values. The model is trained based on previous THN of the user taken during different days. Some embodiments may utilize additional thermal cameras that take thermal measurements of other regions on the face, which may be utilized by the computer to generate additional feature values that are used to detect the allergic reaction. In some cases, detection of the allergic reaction may occur following a rise in nasal temperature, even before the user becomes aware of the allergic reaction.

  • Patent number: 10130299
    Abstract: Thermal measurements of the forehead can be indicative of brain activity, and as such, may be useful for conducting brain-related treatments, such as neurofeedback. In one embodiment, a system for conducting a neurofeedback session includes an inward-facing head-mounted thermal camera (CAM) and a user interface. CAM takes thermal measurements of a region on the forehead (THF) of a user, and is located below the middle of the region. The user interface provides, based on THF, the neurofeedback session for the user. Optionally, a computer controls the neurofeedback session by providing the user feedback via the user interface. The computer may generate the feedback based on the similarity between a current THF pattern and a previous THF pattern of the user taken while the user was in a target state.

  • Patent number: 10130261
    Abstract: Described herein are systems and methods for detecting a physiological response based on thermal measurements while accounting for consumption of a confounding substance such as a medication, alcohol, caffeine, or nicotine. In one embodiment, a system includes a computer and an inward-facing head-mounted thermal camera (CAM) that takes thermal measurements of a region of interest (THROI) on a user's face. The computer receives an indication indicative of the user consuming a confounding substance that affects THROI, and detects the physiological response while the consumed confounding substance affects THROI. The detection is based on THROI, the indication and a model. Optionally, the model was trained on: a first set of THROI taken while the confounding substance affected THROI, and a second set of THROI taken while the confounding substance did not affect THROI.
