Abstract: The invention mainly relates to a system for the inertial unlocking of a seat back, in particular of an aircraft seat, characterized in that it comprises: a structural element of the seat back, called a connecting rod, a support piece for the fixation to a structural element of said seat, the support piece comprising a flyweight movable in translation between: a locking position in which the flyweight faces a lip of the connecting rod so as to prevent the connecting rod from rotating relative to the support piece about the axis of rotation, and an unlocking position in which the flyweight is released from the lip of the connecting rod so as to allow the connecting rod to rotate relative to the support piece about the axis of rotation, the passage of the flyweight from the locking position to the unlocking position being able to be carried out under the action of a deceleration by the seat.

Abstract: System (1) for managing the energy consumption of a building including at least one area, incorporating: a set of sensors (8) capable of generating information representative of environmental parameters; a set of at least one actuator (4-6) capable of acting on the environmental parameters existing in the said area; a computer system (2) designed to receive the said information from the said sensors (8), and to send instructions to the said actuators (4-6), while executing regulation process for the said actuators (4-6) in order to comply, with a set of at least two predetermined criteria; wherein it also incorporates: a routing device (3) connected to the said IT system (2), the said sensors (8) and the said actuators (4-6), designed to transmit information representative of environmental parameters to the IT system (2) and set levels to the said actuators (4-6); a man-machine interface device (10) located in the said area.

Abstract: System (1) for managing the energy consumption of a building including at least one area, incorporating: a set of sensors (8) capable of generating information representative of environmental parameters—in particular the temperature and the brightness prevailing within the area in which they are installed; a set of at least one actuator (4-6) capable of acting on the temperature and/or brightness existing in the said area; a computer system (2) designed to receive the said information from the said sensors (8), and to send instructions to the said actuators (4-6), while executing regulation process for the said actuators (4-6) in order to comply with a set of at least two predetermined criteria; characterized by the fact that it also incorporates: a routing device (3) connected to the said IT system (2), the said sensors (8) and the said actuators (4-6), designed to transmit information representative of environmental parameters to the IT system (2) and set levels to the said actuators (4-6); a man-

Abstract: A double-tube core drill wherein the inner tube (2) is connected to the outer tube (1) by a multi-element needle and/or ball bearing (11), allows for the inner tube (2) to be made rigid and prevents it from rotating along with the outer tube (1). The extraction device (9) and the inner wall (38) of the tube are preferably covered with an antifriction coating. A set of stabilizing elements (67) are spread along the outer tube to stabilize the inner tube (2). Said inner tube has a tapered shoe (32) provided with a lower bevelled lip (14). The drill also comprises a device for indicating that the core has jammed in the inner tube (2) and a sealing device (19) designed to receive a ball (46) provided for sealing the inner tube (2) of said core drill.
