  • ADAPTIVE BALANCING FOR BATTERY MANAGEMENT
    Publication number: 20240001804
    Abstract: A battery balancing system includes an energy balancing circuit. Multiple battery cells are coupled to the energy balancing circuit. A health assessment circuit is coupled to the multiple battery cells and configured to sense a state of health and a charge of each of the multiple battery cells. The balancing circuit switches energy between the multiple battery cells as a function of the sensed state of health and state of charge of each of the multiple battery cells to balance charge there between.
    Type: Application

  • 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.
