Abstract: A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.

Abstract: An access control system and methods according to at least one embodiment leverage wireless access credentials to allow a user to securely gain access to a secured area using his or her mobile device. As such, a credentialed mobile device may permit access to the secured area without requiring a real-time connection to a credential management system and/or an administrative system.

Abstract: Systems and methods for storing and retrieving geospatial data in a geographic information system are provided. Geospatial data can be spatially partitioned along axes of a spherical coordinate system associated with a virtual globe or other spheroid into a plurality of discrete geospatial volumes pursuant to a hierarchical spatial partitioning scheme. For instance, geospatial data can be spatially partitioned into geospatial volumes along surfaces of constant latitude, longitude, and altitude defined by the spherical coordinate system. The discrete geospatial volumes can be stored as nodes in a hierarchical tree data structure. Additional methods are provided for portioning geospatial objects, such as tiles or discrete geospatial volumes, in tritree to reduce polar distortions.

Abstract: Methods and systems for controlling a network access control system that includes a server encrypting a first identifier that can be related to a registered user and communicating the encrypted first identifier to the mobile device. The lock device receives, from the mobile device, a first data set that includes at least the encrypted first identifier. The lock device may encrypt the first data set to generate a second data set and communicates the encrypted second data set to the mobile device. The server receives a third data set that includes at least the encrypted second data set and a second identifier that can also be related to the registered user. The server extracts from the communicated third data set the first and second identifiers, and the extracted first and second identifiers are compared to verify that the second identifier is indeed related to the first identifier.

Abstract: A system and method for enhancing the security associated with the commissioning of an access control device. According to certain embodiments, a commissioning activator is positioned to be accessible from one side of the installed access control device. Thus, the access control device may be installed such that the commissioning activator is accessible to individuals having access to a relatively secure side of the access control device. The displacement of the access control device may generate an activation signal that is detected by a processing device of the access control device. Upon detection of the activation signal, the processing device may activate an input/output device that may transmit an identification signal that is detected by a wireless configuration device. Following receipt of a connection request from the configuration device, the access control device and the configuration device can be connected such that commissioning of the access control device may proceed.
