Abstract: Machine learning-based methods are disclosed to intelligently generate dynamic workflows, such as dynamic call lists and priority levels of alarm notifications. To generate a dynamic call list based on an alarm notification, the system may identify electronic devices present in an area using emitted passive electromagnetic signals (e.g., RF signals such as Bluetooth, WiFi, and/or cellular). The identification of the electronic devices may be associated with known and/or unknown individuals on the premises. The RF signal data may be processed using at least one ML model to determine the severity of the alarm. Based on the processed data, the system may assign a priority level to the alarm, where the priority level may range from level 0 (no action) to level 4 (dispatch law enforcement immediately). The disclosed methods use trained machine learning models to generate a dynamic call list and identify false alarms with increased accuracy.

Abstract: Methods are disclosed to identify and/or count a number of electronic devices present in an area using emitted passive Bluetooth Low Energy (BLE) signals. The identification and/or counting of Bluetooth-enabled devices improves private and public security in determining human presence. Bluetooth-enabled devices passively emit BLE signals for inter-device communication in the form of Bluetooth Advertising Packets. The packets are sent by BLE-enabled devices to search for other known or compatible BLE devices, and advertise information such as media access control (MAC) addresses, device manufacturers, connection capabilities, and manufacturer-specific data. By passively listening to and decoding the observed BLE signals, access to the packets and the metadata they contain is gained. The disclosed methods can include use of other wireless data transfer protocols, such as Bluetooth and Cellular.

Abstract: A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.
