  • Patent number: 11941960
    Abstract: A presence alert system (24) includes a sniffer (36), controller-circuitry (38), radio frequency (RF) background data (40), and a software program (42). The sniffer is configured to sample and measure a characteristic of ambient RF signals (33) over time. The controller-circuitry includes one or more processors and one or more storage mediums. The RF background data is stored in at least one of the one or more storage mediums, and is indicative of no moving presence. The software program is stored in at least one of the one or more storage mediums, and is executed by at least one of the one or more processors. The software program is configured to evaluate the measured characteristic of the ambient RF signals, compare the measured characteristic to the RF background data, and thereby determine motion of a presence (34).

  • Patent number: 11687810
    Abstract: An access control request manager based on learning profile based access pathways in a physical access control system (PACS). The access control request manager including an access pathways learning module configured to determine an reachability graph associated with each resource in the PACS, and a permissions request module, the permissions request module including an access request user interface configured to permit a user or an administrator, to provide a request for a permission to permit the user access to, or revoke the user's access to, a resource in the PACS. The permissions request module determines if the requested permission is already granted to the user, computes a pathway to reach the requested resource based on the reachability graph, suggests a permission, if needed, required to satisfy the request based on the computed pathway, and if approved, adds the suggested permission to any permissions granted to the user.

  • Patent number: 11687164
    Abstract: A method of training a gesture-based access control system includes repetitiously performing an intentional gesture indicative of an intentional gesture type by a user of a mobile device. The intentional gesture is representative of an intent of the user to gain access. The application then forms a model of the selected intentional gesture type from the repetitious performances of the intentional gesture. The model is configured to be applied by the software-based application to confirm future performances of the intentional gesture.

  • Patent number: 11557162
    Abstract: A prestaging, gesture-based, access control system includes a local access assembly, a mobile device, a storage medium, and a processor. The assembly includes a controller to effect actuation between access and no-access states. The mobile device is carried by a user, and includes a detection system configured to detect a prestaging event inherently performed by the user toward an intent to gain access and followed by the detection of a primary intentional gesture specifically performed by the user toward the intent to gain access. The storage medium and the processor are configured to receive prestaging event information and primary intentional gesture information from the detection system, and execute an application to determine the performance of the prestaging event from the prestaging event information, then determine the performance of the primary intentional gesture from the primary intentional gesture information if the prestaging event is determined to have occurred.

  • Patent number: 11546096
    Abstract: A method for communicating data between Bluetooth Low Energy (BLE) devices in a network (100) including multiple nodes (200, 202). The method includes starting a scan mode at a first node (200) having data to send; and determining whether data to send has been transmitted to the first node from an upstream node or a downstream node. If the data to send was received from a downstream node, the first node begins a scan mode. If the data to send was received from an upstream node, the first node begins an ADV event.
