  • Wheelchair propulsion method, kit, and wheelchair implementing such a method
    Patent number: 10252638
    Abstract: A wheelchair having two drive wheels, each provided with a rotary drive motor wherein the value of the drive torque applied by each motor is controlled such as to stabilize the wheelchair, while in motion on the two drive wheels and occupied by a user, in an inclined balance position.
    Type: Grant
    Filed: May 19, 2015
    Date of Patent: April 9, 2019

  • Method and device assisting with the electric propulsion of a rolling system, wheelchair kit comprising such a device and wheelchair equipped with such a device
    Patent number: 10028871
    Abstract: A method for electrically assisting with the propulsion of a rolling system comprising a driving wheel driven by an electric motor, the torque applied by the motor being a function of a propulsion torque transmitted by a user to the driving wheel, wherein the method comprises: a preliminary step of storing in memory an unknown input model representing the weighted system, which is a function of the geometry and of the mass of the weighted system, and having as output data the rotational speed of the driving wheel; a step of estimating unknown input being the total torque applied to the wheel, influencing the rotational speed, the total torque being estimated from the rotational speed by calculating the inverse model; the propulsion torque transmitted by the user being deduced from the total torque estimated on the basis of the other known torques that make up the total torque.

  • Advertising with mobile messaging
    Patent number: 9147204
    Abstract: In accordance with one or more aspects of the content-based advertising in mobile messaging, a message is received from a first mobile device, the received message targeting a second mobile device. One or more advertisements to associate with the message are identified based at least in part on content in the message. Both the message and the one or more advertisements are sent to the second mobile device. The second mobile device receives both the mobile message and the associated one or more advertisements, and displays both the mobile message and the one or more associated advertisements on the mobile device.
