  • Methods, systems, and apparatus for fragmented file sharing
    Patent number: 10423764
    Abstract: Systems, methods, software, and apparatus are described for facilitating the distribution and management of fragmented content. In one embodiment, a packager packages content into fragments and generates a manifest including policies and metadata associated with the content. A downloader obtains the manifest, and uses it to obtain the content from one or more uploaders. For example, a downloader might forward a search request to one or more trackers, which, in turn, are operable to locate one or more uploaders that can meet the request, subject to any relevant policy limitations. The uploaders forward fragments to the downloader, subject to any relevant policy. The downloader assembles the content from the fragments. The operations and interactions of the entities can be subject to policy limitations associated with the fragments, the content as a whole, or the like.

  • Secure transaction systems and methods
    Patent number: 10412071
    Abstract: Systems and methods are described that use tag authentication and presence verification techniques in connection with a variety of transactions. In certain embodiments, an authentication device may verify the authenticity of a secure tag by determining whether the secure tag stores secret information provisioned by a trusted authority. In some embodiments, such an authentication process may be performed without exposing the secret information to the authentication device, thereby maintaining integrity of the secure tag. In other embodiments, insecure tags and/or tags that do not include secret information are used.

  • SYSTEMS AND METHODS FOR CALIBRATING SPEAKERS
    Publication number: 20190253824
    Abstract: Systems and method are disclosed for facilitating efficient calibration of filters for correcting room and/or speaker-based distortion and/or binaural imbalances in audio reproduction, and/or for producing three-dimensional sound in stereo system environments. According to some embodiments, using a portable device such as a smartphone or tablet, a user can calibrate speakers by initiating playback of a test signal, detecting playback of the test signal with the portable device's microphone, and repeating this process for a number of speakers and/or device positions (e.g., next to each of the user's ears). A comparison can be made between the test signal and the detected signal, and this can be used to more precisely calibrate rendering of future signals by the speakers.

  • Secure processing unit systems and methods
    Patent number: 10360411
    Abstract: A hardware Secure Processing Unit (SPU) is described that can perform both security functions and other information appliance functions using the same set of hardware resources. Because the additional hardware required to support security functions is a relatively small fraction of the overall device hardware, this type of SPU can be competitive with ordinary non-secure CPUs or microcontrollers that perform the same functions. A set of minimal initialization and management hardware and software is added to, e.g., a standard CPU/microcontroller. The additional hardware and/or software creates an SPU environment and performs the functions needed to virtualize the SPU's hardware resources so that they can be shared between security functions and other functions performed by the same CPU.
