Abstract: A method of transmitting data over a network, from a sending application to a receiving application, including: coding the data, by the sending application, by implementing a predefined rule; detecting alteration of at least one item of data transmitted, by the receiving application, by implementing the predefined rule; and in case an alteration of a data item is detected, restoring the altered data item. In the course of the coding, in the course of the alteration detection, and in the course of the restoration, a cyclic redundancy check or an encryption can be implemented.

Abstract: Tubular induction motor with two directions of rotation contained in a tube of a tubular actuator designed to be installed in a building. The tubular induction motor includes a squirrel cage rotor supported by bearings and a stator including a stack of metal laminations forming a central bore and centered in the tube, wherein a support part of a bearing is centered in the central bore, wherein the bearing is of the plain and conductor type and wherein it is placed as close as possible to a short-circuiting ring of the rotor, preferably less than 2 mm, and preferably less than 1 mm away.

Abstract: Tubular induction motor (20; 30) with two directions of rotation, contained in a tube (11) of a tubular actuator designed to be installed in a building, comprising a squirrel cage rotor (24; 34) supported by bearings (26; 36; 46) and a stator (12) comprising a stack of metal laminations forming a central bore (12a) and centred in the tube, wherein a support part of a bearing (29; 37; 47) is centred in the central bore, wherein the bearing is of the plain and conductor type and wherein it is placed as close as possible to a short-circuiting ring (24c) of the rotor, preferably less than 2 mm and preferably less than 1 mm away.

Abstract: A control device and corresponding method for controlling a traction function or a braking function of a vehicle, including a moving control lever which can be set in a first position 0 in which neither the traction function nor the braking function are activated, and an unstable position 0i in which the vehicle coasts by reducing electrical traction force and electrical braking force to zero. The control lever can be moved from the first position 0 over a first zone 0+ in which the electrical traction function is activated, either by increasing the electrical traction force, or by decreasing the electrical braking force. The control lever further can be moved from the first position 0 over a second zone 0- in which the electrical braking function is activated, either by decreasing the electrical traction force, or by increasing the electrical braking force.
