  • Geographically secure access to container controller
    Patent number: 11582608
    Abstract: An illustrative example embodiment of a controller associated with a container includes a processor and memory. The controller is configured to generate a derived key based on global positioning system information corresponding to a location of the controller. The controller uses the derived key to authenticate a user device.
    Type: Grant

  • Transport refrigeration unit with a renewable energy source and method of operation
    Patent number: 10712068
    Abstract: A method of operating a multiple energy source of a transport refrigeration unit determines if the transport refrigeration unit is at idle. The method may then electrically switch a condenser fan motor from an electrical power source to a battery charging circuit. The condenser fan motor may be back-driven via wind blowing through a condenser fan. Electrical power is thereby generated and applied to charge a battery via a battery charging circuit.
