  • Patent number: 11951683
    Abstract: A method for improving z-axis strength of a 3D printed object is disclosed. For example, the method includes printing a three-dimensional (3D) object with a polymer and magnetic particles, heating the 3D object to a temperature at approximately a melting temperature of the polymer, and applying a magnetic field to the 3D object to locally move the magnetic particles in the polymer to generate heat and fuse the polymer around the magnetic particles to improve a z-axis strength of the 3D object.

  • Publication number: 20160255079
    Abstract: A method of updating an authentication credential may include, by a client device, receiving an authentication credential from a user, generating an access key using the authentication credential, determining whether the access key decrypts a storage key that encrypts at least a portion of a computer-readable storage medium of the client device, and in response to determining that access key does not decrypt the storage key, sending a request to an authentication server. The request may include the authentication credential. The method may include receiving, from the authentication server, a recovery key, and generating an updated storage key using the decryption key.

  • Publication number: 20150199788
    Abstract: A computer-implemented method for accelerating graphical rendering through legacy graphics compilation is provided. The method includes analyzing one or more graphics API calls of one or more frames of a scene to determine a sequence of graphics API calls which are likely to be unchanged, and translating the determined sequence of graphics API calls into a group of graphics processing unit (GPU) instructions. The method also includes storing the group of GPU instructions in a memory, and rendering a subsequent frame that is subsequent to the one or more analyzed frames using the stored group of GPU instructions. Systems and computer-readable media are also provided.
