  • Patent number: 11944175
    Abstract: A luggage article may include a plurality of walls together defining an outer structure of the luggage article, a wheel bracket attached to and extending from one of the walls, and one or more wheels attached to the wheel bracket. The wheel bracket may comprise a leaf spring having a loop-shaped profile and the one or more wheels may be rotationally attached to a lower end of the loop-shaped leaf spring. The configuration of the wheel bracket may result in higher shock absorption and reduced wheel noise comparative to conventional wheel brackets, and offer an improvement and alternative to conventional luggage wheel brackets.

  • Patent number: 8095132
    Abstract: A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network. The data processing device and the remote system are adapted to store a plurality of parameters identifying a user account belonging to a subscriber. The data processing device comprises a one-time parameter comprising the active account attached to the device designed for a one-time use, and a permanent parameter identifying an account attached to the data processing device, the permanent parameter being deactivated. The one-time and permanent parameter are stored in the at least one remote system, and the microcontroller is programmed to: use the one-time parameter to logon to the network when the data processing device is switched on; and exchanges the one-time parameter with the permanent parameter, upon successful logon to the network, the permanent parameter becoming the permanent active account.
