  "country": "US",
  "title": "Smart Access Control Using Phone Location and Bluetooth",
  "original_title": "Physical access control systems with localization-based intent detection",
  "summary": "This patent describes a system that uses a mobile phone's Bluetooth signal for authentication and Ultra-Wideband (UWB) technology for precise location to figure out if a user intends to open a secured door or asset, then performs an action like unlocking it.",
  "what_it_does": "The system first authenticates a mobile device using a Bluetooth connection, checking if the device is allowed access. Next, it uses Ultra-Wideband (UWB) technology to precisely measure the mobile device's location relative to a reader, like a door lock. Based on this UWB location data and other 'intent criteria,' the system determines if the user actually wants to access the secured asset. If intent is confirmed, the system then performs a 'predefined function,' such as unlocking the door. For example, if you walk up to your smart-locked front door with your phone in your pocket, the system authenticates your phone via Bluetooth, then uses UWB to see you're standing right in front of the door, decides you want to enter, and unlocks it automatically.",
  "what_it_does_not_cover": [
    "Does not cover access control systems that determine a mobile device's location without using Ultra-Wideband (UWB) data.",
    "Does not cover systems where the user's intent to access is determined without considering UWB location data.",
    "Does not cover systems that authenticate the mobile device using only UWB, without a Bluetooth communication connection.",
    "Does not cover systems that do not perform a predefined function after determining user intent, such as just logging presence.",
    "Does not cover access systems that require a physical action like tapping a card or pressing a button after authentication and intent detection."

  "abstract": "A method including authenticating, by an access control system, a credential of a mobile device over a Bluetooth communication connection established between the mobile device and the access control system; receiving, via a reader of the access control system during a UWB ranging session between the mobile device and the reader, UWB data indicative of a location of the mobile device relative to the reader; determining, by the access control system, whether a user of the mobile device intends to access an asset secured by the access control system based on the UWB data and satisfying one or more intent criteria; and performing, by the access control system, a predefined function in response to determining that the user of the mobile device intends to access the asset.",
