Abstract
An electronic door lock including a magnetometer, an accelerometer, and a processor. The processor is configured to determine a status of a door with respect to a door frame using data provided by the accelerometer and magnetometer which collectively generate acceleration data, velocity data and positional data of the door. The processor provides data to a user interface or an alert device indicating one or more of: door open angle, prep-less door position, an acceleration alert, a door position alert, door sag, door frame rub, and triangulation of an intruder.
Claims26
A method for determining a status of a door with respect to a door frame, comprising:
- providing an accelerometer in a door lock;
- providing a magnetometer in the door lock;
- analyzing accelerometer data of the door detected by the accelerometer, wherein the accelerometer data is generated by the accelerometer detecting movement associated with the door and the door frame;
- analyzing magnetometer data of the door generated by the magnetometer, wherein the magnetometer data is generated by the magnetometer detecting a magnetic field associated with the door and the door frame;
- determining whether the accelerometer data and the magnetometer data satisfies a plurality of operating state thresholds, wherein each of the operating state thresholds indicates that operation of the door is operating in an acceptable operating state when the accelerometer data and the magnetometer data satisfies the plurality of operating state thresholds and that operation of the door is operating in an unacceptable operating state when accelerometer data and/or the magnetometer data fails to satisfy at least one of the operating state thresholds;
- providing a status of the door with respect to the door frame when the door is operating in the acceptable operating state;
- and
- providing an alert indicating that an unacceptable condition associated with operation of the door exists when the door is operating in the unacceptable operating state.

An electronic door lock for a door, the lock comprising:
- an accelerometer configured to:
- detect movement associated with the door and the door frame, and
- generate accelerometer of the door based on the movement associated with the door and the door frame;

- and
- a processor is configured to execute stored program instructions to:
- determine whether the accelerometer data and the magnetometer data satisfies a plurality of operating state thresholds, wherein each of the operating state thresholds indicates that operation of the door is operating in an acceptable operating state when the accelerometer data and the magnetometer data satisfies the plurality of operating state thresholds and that operation of the door is operating in an unacceptable operating state when accelerometer data and/or the magnetometer data fails to satisfy at least one of the operating state thresholds, and
- provide a status of the door with respect to the door frame when the door is operating in the acceptable operating state, and
- provide an alert indicating that an unacceptable condition associated with operation of the door exists when the door is operating in the unacceptable operating state.
