  • Publication number: 20220410554
    Abstract: A method for manufacturing a laminated molded body includes a cutting-out step for cutting out a cushion layer to form a cut-out part; a base material laminating step for forming a first laminated body; an insulating material placing step of attaching an insulating material to the cut-out part; a first thermocompression bonding step for bonding the first laminated body by thermocompression; a removing step for removing the cut-out part to form an opening; a skin laminating step for forming a second laminated body; and a second thermocompression bonding step for bonding the skin at the opening part to the lower layer material by bonding the second laminated body by thermocompression, the lower layer material being arranged below the cushion layer having the opening part.

  • Patent number: 10304010
    Abstract: A method includes receiving one or more n-gram vectors for a file as input to a file classifier, where the one or more n-gram vectors indicate occurrences of groups of entropy indicators in a sequence of entropy indicators representing the file. The method also includes generating, based on the one or more n-gram vectors, output including classification data associated with the file, the classification data indicating whether the file includes malware.

  • Patent number: 10068187
    Abstract: A method includes accessing information identifying multiple files and identifying classification data for the multiple files, where the classification data indicates, for a particular file of the multiple files, whether the particular file includes malware. The method also includes generating n-gram vectors for the multiple files by, for each file, generating an n-gram vector indicating occurrences of character pairs in printable characters representing the file. The method further includes generating and storing a file classifier using the n-gram vectors and the classification data as supervised training data.

  • Patent number: 10062038
    Abstract: A method includes accessing information identifying multiple files and identifying classification data for the multiple files, where the classification data indicates, for a particular file of the multiple files, whether the particular file includes malware. The method also includes generating a sequence of entropy indicators for each of the multiple files, each entropy indicator of the sequence of entropy indicators for the particular file corresponding to a chunk of the particular file. The method further includes generating n-gram vectors for the multiple files, where the n-gram vector for the particular file indicates occurrences of groups of entropy indicators in the sequence of entropy indicators for the particular file. The method also includes generating and storing a file classifier using the n-gram vectors and the classification data as supervised training data.

  • Patent number: 9864956
    Abstract: A method includes training a file classifier from one or more n-gram feature vectors received from a plurality of binary files as input, where the one or more n-gram vectors represent the occurrences of character pairs in printable characters within the file or characters representing the informational entropy sequence of the file. Another method also includes generating, by the file classifier, output including classification data associated with the file based on the one or more n-gram vectors, where the classification data indicates whether the file includes malware.

  • Patent number: 8022454
    Abstract: Ferroelectric structures and methods of making the structures are presented. The ferroelectric structures can include an electrode in contact with a ferroelectric thin film. The contact can be arranged so that a portion of the atoms of the ferroelectric thin film are in contact with at least a portion of the atoms of the electrode. The electrode can be made of metal, a metal alloy, or a semiconducting material. A second electrode can be used and placed in contact with the ferroelectric thin film. Methods of making and using the ferroelectric structures are also presented.
