  • Method and system for activity detection with obfuscation
    Patent number: 12041359
    Abstract: A camera system includes a camera configured to capture first video of a scene in the form of first image frames. The camera system also includes an infrared sensor configured to capture second video of the scene in the form of second image frames. The system also includes a processor in communication with the camera and the infrared sensor. The processor is configured to obfuscate one or more portions of the scene.
    Type: Grant

    Date of Patent: July 16, 2024
    Assignee: Northwestern University
    Inventors: Nabil I. Alshurafa, Josiah D. Hester
  • Batteryless sensor for detecting occupancy and activity
    Patent number: 11536832
    Abstract: This system is directed to a batteryless, self-powered sensor comprising: a microprocessor; a first and second solar panel in electronic communications with the microprocessor; a transceiver in communication with the microprocessor; and a set of computer readable instructions included in the microprocessor adapted for creating motion data including a direction and a speed of movement of object within a first sensing area and a second sensing area, transmitted the motion data to a remote location if sufficient power is provided by the first solar panel to actuate the transceiver and a number of data points in the motion data exceeds a pre-determined number of minimal data points, associating a reduction in power delivered from the first solar panel to the microprocessor with movement and associating an increase in power delivered from the first solar panel to the microprocessor with movement.
