  • Chemiresistor humidity sensor and fabrication method thereof
    Patent number: 11460427
    Abstract: A sulfonated nanocellulose or sulfonated cellulose may be synthesized. A polyaniline emeraldine may be doped with the sulfonated nanocellulose or sulfonated cellulose to form a sulfonated nanocellulose-doped polyaniline or a sulfonated cellulose-doped polyaniline.
    Type: Grant
    Filed: October 31, 2018
    Date of Patent: October 4, 2022
    Assignee: Cyberswarm, Inc.
    Inventors: Bogdan Catalin Serban, Octavian Buiu, Octavian Ionescu, Andrei Buiu
  • Cyber security system for internet of things connected devices
    Patent number: 10972486
    Abstract: A security system may include a normally open relay between an external network connection and at least one internal network connection, a network controller, and a microcontroller. The network controller may be configured to monitor for malicious activity on an external network accessible through the external network connection. The microcontroller may be configured to cause the normally open relay to temporarily close in response to the network controller failing to detect the malicious activity for a predetermined amount of time and cause the normally open relay to remain open and generate an alert in response to the network controller detecting the malicious activity.
