Method for triggering positioning of portable key device in access control
A recently granted patent (Publication Number: US11967194B2) discloses a method for determining the optimal timing to trigger the positioning of a portable key device used in access control for an electronic lock that regulates entry to a restricted physical space. The method involves obtaining movement data from a motion sensor on the key device, identifying a stop in motion, and then initiating the positioning process to indicate the key device's position relative to the physical space. This method ensures that the key device is not positioned until a complete stop in motion is detected, enhancing the accuracy of the positioning process.
Furthermore, the patent includes additional features such as authenticating the key device with the electronic lock using a specific communication protocol, utilizing machine learning models to predict stoppage in motion based on movement data, and triggering repetitive positioning during a defined time period. The positioning determiner, which includes a processor and memory, executes instructions to carry out these functions effectively. By incorporating various communication protocols, machine learning capabilities, and precise motion detection criteria, the patent aims to enhance the efficiency and reliability of access control systems utilizing portable key devices for electronic locks in restricted physical spaces.
