Abstract: A detection sensor or a user device is used to aid in providing authentication and activation of a door system when a user tries to access the door for ingress and egress. Operating parameters of the door systems may be set to allow ingress and egress only when a user is identified and authorized. As such, the operating parameters of the door systems may include authentication and activation parameters such that the door systems are controlled, at least in part, based on the presence of a user and/or a user device and the identification of the specific user. As such operating parameters may be different for different users or types of users. Moreover, the user device may be used to authenticate a user and control ingress and egress through the door automatically or through an authentication action taken by the user.

Abstract: A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

Abstract: A method of isolating hidden data in a solid state memory system is disclosed including obtaining a logical block address (LBA) image from the memory system, obtaining a physical block address (PBA) image, determining whether an error exists in the PBA image and correcting the error, calculating an ETCRC on each sector of the LBA image and building a search tree indexed on the ETCRC value. For each sector in the PBA image, the method also includes computing an error tolerant cyclic redundancy check (ETCRC) value and searching for the ETCRC value in the LBA search tree. If the ETCRC value is found, also included is comparing the cyclic redundancy check (CRC) of the LBA and PBA sectors, and outputting to an output file the PBA sector as hidden data if either the ETCRC value is not found in the LBA search tree or the CRC comparison fails.
