Abstract: A facility for pairing a metal shield to a leading edge of a preform made of composite material for the production of an aircraft turbine engine blade, the facility including a support configured to receive and hold the metal shield, —a movement hexapod which carries the support and is able to move the support along and about the three axes of an XYZ coordinate system, —an automaton which includes jaws and is configured to receive and hold the preform, and—a computing unit for controlling the hexapod and the automaton with a view to producing the pairing. The invention also relates to a method for pairing the metal shield to the leading edge of the preform made of composite material for the production of the aircraft turbine engine blade.

Abstract: An extrusion head for additive manufacturing includes an enclosure defining a supply chamber. The enclosure includes at least one inlet port opening into the supply chamber and configured to receive a material to be extruded under pressure and a plurality of extrusion nozzles.

Abstract: An electric motor assembly device includes a carrier member with a central passage that receives a rotor shaft with a commutator. Brushes secured onto flexible, brush holders urge the brushes towards the central passage into a contact position with the commutator. The carrier member has mechanical elements for restraining the brush holders in an assembly position for assembly where the brushes clear the central passage and are protected against impact by the carrier member. This arrangement allows the rotor shaft to be introduced into the central passage of the carrier member without a risk of damaging the brushes. The brush holders are easily released automatically from the mechanical elements on the electric motor assembly device to bring the brushes into the contact position.

Abstract: An apparatus configured to process a digital video signal comprising an input circuit, a processing circuit and an encoder circuit. The input circuit may be configured to present a digital video signal comprising a plurality of frames. The processing circuit may be configured to detect scene changes in the digital video signal by analyzing (i) a current one of the plurality of frames and (ii) two or more other frames. The encoder circuit may be configured to generate an encoded signal in response to the digital video signal and the scene changes. The two or more other frames may comprise (i) a first window of frames that are processed before the current frame and (ii) a second window of frames that are processed after the current frame. The processing circuit may also detect the scene changes by analyzing changes between the first window and the second window.

Abstract: A commutator housing for an electric motor includes a support to receive a commutator having at least two integrated stops and at least two brushes each fixed on a spring component. The spring components force the brushes into a contact position against the commutator. The stops hold the spring components in a mounting position in which the brushes are distanced from the contact position.

Abstract: A control system for vehicle doors and windows in a vehicle door includes a first openable member, such as a vehicle door, a second openable member, such as a window in the door, and a logic unit that commands the second openable member to open in the event the first openable member fails to open. The logic unit preferably commands a window regulator to actuate if the door fails to open. The vehicle door can be fitted with the system. A method includes the step of commanding the second openable member to open with the logic unit in the event the first openable member fails to open.
