  • Methods, systems, and products for image displays
    Patent number: 9891370
    Abstract: Methods, systems, and products illuminate display devices. An image is injected into a waveguide. The image propagates at total internal reflectance within the waveguide. A frustrator withdraws a frustrated image from the waveguide, and the frustrated image may be displayed to a viewer.

  • Methods, systems, and products for authentication of users
    Patent number: 9881149
    Abstract: Methods, systems, and products authenticate users for access to devices, applications, and services. Skills of a user are learned over time, such that an electronic model of random subject matter may be generated. The user is prompted to interpret the random subject matter, such as with an electronic drawing. The user's interpretation is then compared to the electronic model of the random subject matter. If the user's interpretation matches the electronic model, the user may be authenticated.

  • Electromagnetic reflection profiles
    Patent number: 9874632
    Abstract: Methods, systems, and products determine electromagnetic reflective characteristics of ambient environments. A wireless communications device sends a cellular impulse and receives reflections of the cellular impulse. The cellular impulse and the reflections of the cellular impulse may be compared to determine the electromagnetic reflective characteristics of an ambient environment.

  • Indexing Auxiliary Domains
    Publication number: 20170193113
    Abstract: Methods, systems, and products determine intradomain and interdomain search results. When a website query is received, the website query specifies a domain and a search term. The intradomain search results are generated by searching the domain for the search term. The interdomain search results, though, are generated by searching auxiliary domains for the search term.

  • NANO-COMPOSITE STRUCTURE AND PROCESSES MAKING OF
    Publication number: 20170190970
    Abstract: A nano-composite structure comprises of an amorphous matrix with embedded nano-crystallites. The nano-crystallites are precipitated from the amorphous matrix via heat treatment of a solution mixture of metal salts or metalorganic compounds to an appropriate temperature range and with a suitable duration, or heating of a mixture of non-crystalline compounds. The nano-crystallites are self-assembled in the amorphous matrix without forming agglomerates or distinguished grain boundaries. The nano-composite structure can be used for transparent display, transparent optical ceramics, protection armor, nuclear protection, pulsed power, high voltage electronics, high energy storage system and high power microwave systems.

  • Methods, Systems, and Products for Recalling and Retrieving Documentary Evidence
    Publication number: 20170132254
    Abstract: Methods, systems, and products help users recall memories and search for content of those memories. When a user cannot recall a memory, the user is prompted with questions to help recall the memory. As the user answers the questions, a virtual recollection of the memory is synthesized from the answers to the questions. When the user is satisfied with the virtual recollection of the memory, a database of content may be searched for the virtual recollection of the memory. Video data, for example, may be retrieved that matches the virtual recollection of the memory. The video data is thus historical data documenting past events.

  • Dynamically Served Content
    Publication number: 20170099342
    Abstract: Methods, systems, and products determine a best version of webpage. A webpage may have many different versions, with each different version tailored to parameters associated with a client device. A database of content associates the different versions to different combinations and/or ranges of the parameters. When the client device requests the webpage, the parameters are retrieved and the corresponding version is selected and sent.
