Motion-Triggered Electronic Key for Secure Access Control

The patent replaces traditional mechanical lock cylinders with electronic or electro-mechanical locks that use electronic keys containing microprocessors and memory. This substitution enables enhanced access control functionality including remote administration, credential updating, and motion-based operations while managing the complexity through integrated electronic systems.

The patent implements a feedback mechanism where electronic keys can communicate with remote administration devices via wireless communications. The keys store access control information locally for reliable operation, while also enabling bidirectional communication that allows administrators to remotely update credentials, modify access rights, and receive status reports, thus resolving the contradiction between local reliability and remote manageability.

The patent implements periodic action by enabling wireless communication only at specific intervals or upon triggering events rather than continuously. The electronic key can enter low-power states between communication sessions, reducing energy consumption while still allowing remote administration when needed. Motion detection sensors can trigger communication events, ensuring the system remains responsive without constant power consumption.

The patent applies self-service by using the electronic key's existing motion detection sensors (such as accelerometers) to automatically detect movements and trigger appropriate security responses without requiring external monitoring systems. The key autonomously determines when motion corresponds to predefined enabling movements and initiates wireless communication or access control actions, enhancing security while minimizing additional complexity by utilizing integrated components.
