  • DEVICE FOR AN ELECTRIC VEHICLE, ELECTRIC VEHICLE HAVING A DEVICE, AND METHOD FOR PROVIDING CHARGING ENERGY
    Publication number: 20240083281
    Abstract: An apparatus for an electric vehicle having a battery interface, an inverter, a switch device and a control device. The inverter has a first terminal for connecting the inverter to the battery interface and a second terminal for connecting the inverter to a switch terminal. The inverter is formed to convert a DC voltage applied to the first terminal into an AC voltage and to provide the latter to the second terminal. The switch device has the switch terminal that connects the switch device to the second terminal and an energization interface for energizing a further electric vehicle coupled to the energization interface.

  • Method for pairing and authenticating one or more medical devices and one or more remote electronic devices
    Patent number: 8533475
    Abstract: A method for authenticating a medical device and a remote electronic device may include generating a PIN code by one device, capturing the generated PIN code with the other device, checking authentication of the PIN code, which is based at least in part on the captured PIN code, by the one device, generating a strong key by the one device, sending the strong key encrypted to the other device, checking authentication of the sent strong key by the one device, and upon successful authentication, storing the strong key in a memory of the one device and the other device. The roles of the medical device and the remote electronic device may be reversed in the authenticating method. The authenticating method may be preceded by a pairing process and/or followed by a binding process.
