Abstract: A forming system includes a femtosecond laser and a control unit that includes one or more processors operatively connected to the femtosecond laser. The femtosecond laser is configured to emit laser pulses onto an inner surface of a face sheet of an acoustic inner barrel. The acoustic inner barrel includes an acoustic core comprising an array of hexagonal cells attached to an outer surface of the face sheet that is opposite the inner surface. The control unit is configured to control the femtosecond laser to laser drill a plurality of perforations in the face sheet via emitting laser pulses at pulse durations between about 100 femtoseconds and about 10,000 femtoseconds and at frequencies over 100,000 Hz.

Abstract: Some embodiments include an x-ray device comprising: an access port configured to receive a cathode within an interior volume of an enclosure of the x-ray device; a first vacuum seal configured to seal a cover over the access port; and a second seal configured to seal the cover over the access port, the second seal maintained between the first vacuum seal and the interior volume of the enclosure during removal of the first vacuum seal.

Abstract: Systems and methods for detecting objects and predicting their motion are provided. In particular, a computing system can obtain a plurality of sensor sweeps. The computing system can determine movement data associated with movement of the autonomous vehicle. For each sensor sweep, the computing system can generate an image associated with the sensor sweep. The computing system can extract, using the respective image as input to one or more machine-learned models, feature data from the respective image. The computing system can transform the feature data into a coordinate frame associated with a next time step. The computing system can generate a fused image. The computing system can generate a final fused image. The computing system can predict, based, at least in part, on the final fused representation of the plurality of sensors sweeps from the plurality of sensor sweeps, movement associated with the feature data at one or more time steps in the future.

Abstract: A collaborative content management system receives, from a client device having access to an account associated with the collaborative content management system, a request for versions of a collaborative document managed by the collaborative content management system. The collaborative content management system accesses a set of versions of the collaborative document. The set of versions includes at least one offline version. The at least one offline version was created on a client device having access to the collaborative document while the client device was disconnected from the collaborative content management system and synchronized to the collaborative content management system when the client device is connected to the collaborative content management system. The collaborative content management system generates a user interface providing the set of versions.
