  • Publication number: 20200326772
    Abstract: A system for multi-track playback of media content includes: a media device; a user interface, provided at the media device, which displays a visual array of media options, a playback logic, provided within the media device, which is configured so that, while a selected point or region is determined by the user interface as being moved in response to user input, within the visual array of media options, the system determines media options that are proximate to the selected point or region, and adjusts playback parameters for corresponding media content items, by crossfading or otherwise combining playback to reflect the media options relative distances from the selected point or region; and a tempo logic, provided within the media device, which is configured to provide or receive a selected tempo and provide the one or more media content items associated with the selected tempo.

  • Patent number: 10773960
    Abstract: A method for controlling density, porosity and/or gap size within a nanotube fabric layer is disclosed. In one aspect, this can be accomplished by controlling the degree of rafting in a nanotube fabric. In one aspect, the method includes adjusting the concentration of individual nanotube elements dispersed in a nanotube application solution. A high concentration of individual nanotube elements will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a lower concentration will tend to discourage rafting. In another aspect, the method includes adjusting the concentration of ionic particles dispersed in a nanotube application solution. A low concentration of ionic particles will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a higher concentration will tend to discourage rafting. In other aspects, both concentration parameters are adjusted.

  • Publication number: 20200262701
    Abstract: The present disclosure provides scalable nanotube fabrics and methods for controlling or otherwise adjusting the nanotube length distribution of a nanotube application solution in order to realize scalable nanotube fabrics. In one aspect of the present disclosure, one or more filtering operations are used to remove relatively long nanotube elements from a nanotube solution until nanotube length distribution of the nanotube solution conforms to a preselected or desired nanotube length distribution profile. In another aspect of the present disclosure, a sono-chemical cutting process is used to break up relatively long nanotube elements within a nanotube application solution into relatively short nanotube elements to realize a pre-selected or desired nanotube length distribution profile.

  • Patent number: 10712963
    Abstract: Technologies for encrypted data access by field-programmable gate array (FPGA) user kernels include a computing device having an FPGA and an external memory device accessible by the FPGA. The FPGA includes a secure key store, a micro-encryption engine, and multiple slots for user kernels that are each identifiable with an index. A user kernel is programmed at an index and a symmetric encryption key is provisioned to the secure key store at the index. The micro encryption engine may read encrypted data from the external memory device, decrypt the encrypted data with the key associated with the index of the user kernel, and forward plain text data to the user kernel. The micro encryption engine may also receive plain text data from the user kernel, encrypt the plain text data with the key, and write the encrypted data to the external memory device. Other embodiments are described and claimed.

  • Patent number: 10661304
    Abstract: A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.

  • Publication number: 20190292057
    Abstract: Methods for forming a nanotube fabric with a controlled surface roughness (or smoothness) and a selected degree of rafting are disclosed by adjusting the concentration levels of a selected ionic species within a nanotube formulation used to form the nanotube fabric. In one aspect, the present disclosure provides a nanotube formulation roughness curve (and methods for generating such a curve) that can be used to select a utilizable range of ionic species concentration levels that will provide a nanotube fabric with a desired surface roughness (or smoothness) and degree of rafting. In some aspects of the present disclosure, such a nanotube formulation roughness curve can be used adjust nanotube formulation prior to a nanotube formulation deposition process to provide nanotube fabrics that are relatively smooth with a low degree of rafting.
