Abstract: Counterbalance assemblies include a torsion bar spring for counter-balancing the weight of upwardly opening aircraft doors for ease of opening and closing. The torsion bar spring may be linked to the aircraft door through an integrated gear reduction system comprised of two pairs of spur gears and respective shafts as well as a linkage assembly. A cable reel is connected to the output shaft and the input shaft is connected to a four bar linkage system attached to the end of the torsion bar. The cable reel stores the lift cable and provides the output torque to lift the aircraft door. When the aircraft door opens or closes, the center of mass loses or gains height respectively, causing a variation of gravitational potential energy. In such a manner, the gravitational potential energy is exchanged with strain elastic energy from the counter-balance spring therefore reducing the required external source of energy whether it is from a power assisted means or manual operation.

Abstract: A method for generating an interactions explorer for a user interface prototype comprising detecting one or more prototyping actions while a user creates a user interface prototype, adding the one or more prototyping actions to an interaction hierarchy and generating an interactive visual depiction of the interaction hierarchy.

Abstract: The present system enables the monitoring and automatic control of the tolerance in splice overlap of textile play , though the identification of the overlap area, identification and counting of textile cords in the overlap area, and the generation of a control signal for the manufacturing equipment based on parameters and criteria defined by a user. The system includes an image acquisition sub-assembly that contains a lighting module, artificial vision module, and respective elements of support, fixation, conditioning and adjustment. The system also includes a quality control computer program that has a module of morphologic image analysis for detection and recognition of the overlap of the ply, detecting and counting of cords in the overlap area, a module of support to the decision of acceptance/rejection of the ply based on parameters defined by the user and a module of an interface with production equipment.
