  • Patent number: 12183094
    Abstract: A method and system for training a machine learning model for point of gaze prediction simultaneously analyzes the image of the scene and the image of the driver's face using the machine learning model to generate a point of gaze of a driver in traffic environments. The machine learning model comprises a camera calibration module that can compute an embedding vector that represents the spatial configuration between the driver and the camera system. The camera calibration module improves the overall model's performance, which is jointly trained end to end.

  • Publication number: 20240374214
    Abstract: Disclosed herein are embodiments of a continuous multi-analyte monitor that can be used to measure one or more analytes, for example pH and lactate, in a patient. In some embodiments, the sensor can be implanted in the tissue of a patient, and a recording unit can be located on the skin of the patient, generally adjacent to the sensor. Detectors located on the sensor and on the recording unit can detect luminescent signals that originate from the implantable sensor and can be used to determine analyte concentrations, or otherwise relevant values.

  • Publication number: 20240212365
    Abstract: A biometric sensing system for an aircraft cockpit includes an infrared camera, infrared illuminators, and a CPU. The infrared camera is mounted in a flight deck display surface of the cockpit and has a field of view including an upper body region of a flight crew member when the flight crew member is seated in the cockpit. The infrared illuminators are mounted in the flight deck display surface and directed to illuminate the upper body region of the flight crew member when the flight crew member is seated in the cockpit. The CPU can communicate instructions to the infrared camera and infrared illuminators, receive image data captured by the infrared camera, and process the image data captured by the infrared camera in order to determine an alertness level of the flight crew member based on at least one biometric characteristic within the captured image data.

  • Patent number: 12014469
    Abstract: The Invention presents a system and a method for digitizing a human body shape from anthropometrical measurements. The proposed system and method allow reconstructing the 3D human body quickly and accurately, improving disadvantages of costly and timely traditional methods, which not only requires digitized persons to be naked or wear tight clothes but also could use hazardous lights to their health. The system in the invention includes two main modules and two supplementary blocks to reconstruct the 3D human body from anthropometric measurements, which are: (1) Input Block, (2) Pre-Processing Module, (3) Optimization Module, (4) Output Block. The method in the invention includes four steps: (1) Step 1a: collecting human body measurements, (2) Steps 1b: Initial Population; (3) Step 2: Optimizing; (4) Step 3: Displaying digitized human body shape.
