The blade includes an airfoil having a pressure side and a suction side which extend from a leading edge to a trailing edge of the airfoil. The blade further includes a metal sheath that extends along the leading edge of the airfoil. The process includes the steps of: placing a preform, produced by three-dimensionally weaving fibers, in a mold, the sheath being positioned on an edge of the preform intended to form the leading edge of the airfoil; and injecting polymerizable resin into the mold to impregnate the preform so as to form the airfoil after solidifying. At least one double-sided adhesive film may be inserted between the sheath and the edge of the preform prior to injection of the resin.

Abstract: Methods, systems and apparatus, including computer programs encoded on computer storage media, for training a policy neural network by repeatedly updating the policy neural network at each of a plurality of training iterations. One of the methods includes generating training data for the training iteration by controlling the agent in accordance with an improved policy that selects actions in response to input state representations. A best response computation is performed using (i) a candidate policy generated from respective policy neural networks as of one or more preceding iterations and (ii) a candidate value neural network. The candidate value neural network is configured to generate a value output that is an estimate of a value of the environment being in the state characterized by a state representation to complete a particular task. The policy neural network is updated by training the policy neural network on the training data.

The electronic device includes processing circuitry that is operatively coupled to the display and configured to foveate one or more areas of the display according to the eye tracking data. If the eye tracking data input is lost, the processing circuitry is configured to recover from the loss of eye tracking data by changing one or more aspects of the foveated areas (e.g., size, resolution, etc.) until a threshold is satisfied. As time elapses since loss of eye tracking, the foveated areas move toward a center or a salient region of the display.

Abstract: A multi-layer low-pass filter is used to filter a first frame of video data representing at least a portion of an environment of an individual. A first layer of the filter has a first filtering resolution setting for a first subset of the first frame, while a second layer of the filter has a second filtering resolution setting for a second subset. The first subset includes a data element positioned along a direction of a gaze of the individual, and the second subset of the frame surrounds the first subset. A result of the filtering is compressed and transmitted via a network to a video processing engine configured to generate a modified visual representation of the environment.

Abstract: Embodiments of the present invention teach use of a single-platform with its own authentication-process (i.e., its own “single-platform-authentication-process” or its own selection of secure single-platform-authentication-processes), but that may allow third party service provider companies (Organizations) that want to offer/provide service(s) on the single-platform, to still utilize their own authentication-processes, i.e., to still utilize the given Organization's own “organization-specific-authentication-process,” at least once in the initial user onboarding process, and thereafter to rely upon the common authentication-processes of the single-platform; which then permits a multitude of services, including the possibility of diverse and different services to be deployed from the single-platform.
