  "title": "Using Millimeter Waves to Map Your Surroundings for Better Location",
  "original_title": "System, method and computer-accessible medium for real time imaging using a portable device",
  "summary": "This patent describes a way for a mobile device to use millimeter wave signals to understand its environment and pinpoint its location by analyzing how those signals bounce off surfaces.",
  "what_it_does": "This invention uses millimeter wave (mmWave) radio frequency signals to create a map and determine a device's location. A transmitting device sends out these signals, which then bounce off surfaces like walls or furniture, creating 'multipath components.' The device receives these bounced signals and analyzes information from them, such as the angle they arrived (AoA) or when they arrived (time of arrival). Using this data, along with a stored map, a ray tracing process calculates the device's precise location. It can then generate images or video of the surroundings, potentially showing other objects in the environment. For example, a phone could use this to show a user exactly where they are in a large building or to highlight obstacles.",

    "Systems that do not analyze multipath components of the RF signal.",
    "Methods that do not determine at least two pieces of information like AoA, AoD, time of arrival, RTA, or phase.",
    "Techniques that do not use a stored 2D or 3D map of the environment.",
    "Processes that do not employ a ray tracing calculation to determine location."

  "abstract": "An example system and method provides radiating into the 3D environment a millimeter wave (mmWave) radio frequency (RF) radiation signal that interacts with reflective surfaces, penetrable surfaces, scattering surfaces of the 3D environment, producing respective multipath components, determining information from two or more of the multipath components, including two among, or, optionally, all of angle of arrival (AoA), angle of departure (AoD), time of arrival, relative time of arrival (RTA), and phase and, based on the information and the received multipath components, performs computing the user device’s relative or absolute mobile device location in relation to the surrounding 3D environment, and providing images or video of the surrounding 3D environment to a display or a storage of the user’s mobile device, for displaying or storing.",
