  • Patent number: 12649274
    Abstract: A pick and place end effector configured to form a kink in a composite laminate. The pick and place end effector comprises a vacuum lift face configured to hold the composite laminate and move from a flat configuration to a forming configuration with an angle in the vacuum lift face to form the kink in the composite laminate; a number of motors configured to move the vacuum lift face between the flat configuration and the forming configuration; and a number of restraints configured to clamp portions of a composite laminate on opposite sides of the kink on the vacuum lift face during movement between the flat configuration and the forming configuration.

  • Patent number: 11840361
    Abstract: The magnetic handling systems comprise a bladder and a magnetic carriage system. The bladder is configured to be received within a stringer interior volume of a hat stringer and comprises a magnetic insert having a plurality of magnetic walls, each configured to align with a respective wall portion of the hat stringer. The magnetic carriage system comprises a carriage having a magnetic head that comprises a bracket and a plurality of magnetic sources supported by the bracket. Each magnetic source is configured to magnetically couple with a respective magnetic wall of the magnetic insert to produce an attractive magnetic force therebetween. The methods comprise disposing a bladder having a plurality of the magnetic inserts within the hat stringer, magnetically engaging a plurality of the magnetic heads with the plurality of magnetic inserts, and conforming the hat stringer by moving at least one magnetic head relative to another magnetic head.

  • Patent number: 7835719
    Abstract: In a radio network that includes at least one base station and at least one remote station, signals are modulated for transmission from the remote stations by embedding known information throughout the signal in a predetermined pattern and a group of sample vectors of a signal received by at least one base station of the network are collected and processed to detect a said received signal that resulted from propagation of a signal from a remote station of the network. The group of sample vectors is collected from (a) signals that are received by more than one base station of the network; and/or (b) signals that are received simultaneously at different frequencies by at least one base station of the network.
