  • Publication number: 20190158906
    Abstract: Apparatus and methods for recording a media stream for use by a rendering device. In one embodiment, a client device records live, unbound streaming media content from a Content Delivery Network (CDN) in “chunks” according to a data structure such as a manifest file. The live media content stream chunks are compressed and stored for later playback. The client device uses information regarding the chunks to generate a local manifest file, which it then uses to reconstruct the media stream. A video client may also dynamically insert and account for updated secondary content (such as advertisements) during each playback instance, thus enabling the service provider to realize commercial opportunities which were previously not possible. Various operational/business rules are also disclosed for e.g., enabling and disabling functions with respect to playback of the content.

  • Publication number: 20190147044
    Abstract: A natural language processing system has a hierarchy of user intents related to a domain of interest, the hierarchy having specific intents corresponding to leaf nodes of the hierarchy, and more general intents corresponding to ancestor nodes of the leaf nodes. The system also has a trained understanding model that can classify natural language utterances according to user intent. When the understanding model cannot determine with sufficient confidence that a natural language utterance corresponds to one of the specific intents, the natural language processing system traverses the hierarchy of intents to find a more general user intent that is related to the most applicable specific intent of the utterance and for which there is sufficient confidence. The general intent can then be used to prompt the user with questions applicable to the general intent to obtain the missing information needed for a specific intent.

    Abstract: This invention discloses a semiconductor power device disposed in a semiconductor substrate and the semiconductor substrate has a plurality of trenches. Each of the trenches is filled with a plurality of epitaxial layers of alternating conductivity types constituting nano tubes functioning as conducting channels stacked as layers extending along a sidewall direction with a “Gap Filler” layer filling a merging-gap between the nano tubes disposed substantially at a center of each of the trenches. The “Gap Filler” layer can be very lightly doped Silicon or grown and deposited dielectric layer. In an exemplary embodiment, the plurality of trenches are separated by pillar columns each having a width approximately half to one-third of a width of the trenches.

  • Publication number: 20190112909
    Abstract: The invention provides techniques that relate to horizontal well completions that facilitate multistage fracturing, for example, in shale gas reservoirs. Aspects of these techniques involve the creation of large scale fracture networks, connecting the reservoir and the wellbore, facilitated by activating pre-existing natural fractures (NFs). Taking into account selected shale formation geo-mechanical characteristics facilitates the optimization of maximum stimulated reservoir volumes (SRVs). In particular, completion optimization patterns are provided for horizontal wellbores, designated herein as altered alternate fracturing (AAF) completions. Aspects of this approach involve a multi-step combination of simultaneous and alternate fracturing patterns. To illustrate aspects of optimization, the dynamic evolution and progression of NF growth are modeled using a variety of alternative criteria. In addition, specific analyses are provided of how the well completion pattern influences the fracture network.

    Abstract: A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The catheter includes an inflatable balloon mounted on a distal end region of the catheter shaft of the catheter. The catheter shaft includes a guidewire lumen having a distal opening and a lateral opening in a distal region of the catheter shaft proximal of the distal opening, and an inflation lumen in fluid communication with the balloon. The balloon is configured to be inflated in the subintimal space to a first inflation state at inflation pressures below a threshold inflation pressure to orient the lateral opening toward the lumen of the blood vessel, and inflated to a second inflation state at inflation pressures above the threshold inflation pressure. The catheter includes means for retaining the balloon in the first inflation state at pressures below the threshold inflation pressure.

  • Patent number: 10025714
    Abstract: A computer system includes a dual in-line memory module (DIMM), such as a registered DIMM (RDIMM), and a non-volatile DIMM (NVDIMM). A central processing unit (CPU) of the computer system has internal cache memory locations for caching data for the DIMM and NVDIMM. A memory type range register (MTTR) of the CPU is set for write-back cache strategy for a range of memory locations in the DIMM and NVDIMM. The computer system includes a power supply that, in the event of a power failure, triggers a hardware non-maskable interrupt (NMI) and sustains power to the CPU to allow cached data to be saved to non-volatile memory locations in the NVDIMM before the computer system completely powers down.
