  • Publication number: 20230046064
    Abstract: A computer-implemented method comprises generating computer executable code as one or more code portions; detecting a number of processing operations required to reach one or more predetermined stages in execution of each code portion; and associating with each code portion one or more progress indicators, each representing a respective execution stage of the one or more predetermined stages within execution of that code portion. The code portions are executed by a processor powered by an unpredictable power source. When the processor detects an energy condition indicating that no more than a reserve quantity of electrical energy is available, the progress indicators are used to determine whether or not to perform a checkpoint.

  • Publication number: 20230038982
    Abstract: A method for automatic speech recognition using joint acoustic echo cancellation, speech enhancement, and voice separation includes receiving, at a contextual frontend processing model, input speech features corresponding to a target utterance. The method also includes receiving, at the contextual frontend processing model, at least one of a reference audio signal, a contextual noise signal including noise prior to the target utterance, or a speaker embedding including voice characteristics of a target speaker that spoke the target utterance. The method further includes processing, using the contextual frontend processing model, the input speech features and the at least one of the reference audio signal, the contextual noise signal, or the speaker embedding vector to generate enhanced speech features.

  • Patent number: 11575595
    Abstract: A digital crosspoint switch of a network switching system (NSS) replicates input data received via a first network interface to a first data processing port of a data processing card. The input data includes a digital market data feed comprising market-data packets. The crosspoint switch has internal crosspoint ports and external crosspoint ports. The data processing card includes a programmable logic device and a plurality of data processing ports connected to the internal crosspoint ports. The NSS includes a plurality of network interfaces connected to the external crosspoint ports. The data processing card processes the input data and generates processed data on the second data processing port at least in part by only including market-data packets that meet a first predetermined filtering criterion in the processed data. The crosspoint switch replicates the processed data from the second data processing port to the second network interface.

  • Publication number: 20230035661
    Abstract: An interposer is described that is made from an electrically insulating, thermally efficient substrate (e.g., sapphire) and has a load hole for use with ion traps in atomic-based QIP architectures. The interposer load hole aligns with a load hole in the ion trap such that atomic species can be provided from the back of the interposer to the front of the ion trap for ionization and confinement. The interposer may include angled traces for wire bonding to the ion trap, where the angled traces enable more open light access when using laser or optical beams during operation of the ion trap. Electrical routing in the interposer may involve more than one layer of routing, separated by an insulating dielectric material such as a polyimide. Routing in the interposer may also contain active electronic components. The load hole in the interposer may have a straight or tapered inner wall.

  • Patent number: 11561984
    Abstract: Presently disclosed are systems and methods for generating customized filtered-and-partitioned market-data feeds. In an embodiment, an output-feed profile is maintained in data storage at a market-data-processing device (MDPD). The output-feed profile specifies a subset of ticker symbols and a ticker-symbol-based feed-partitioning scheme. An input feed of order-book updates to ticker symbols is received at the MDPD from an upstream device. At the MDPD, a customized market-data output feed is generated according to the maintained output-feed profile at least in part by filtering the input feed down to the order-book updates to ticker symbols in the specified subset and partitioning the filtered feed according to the specified ticker-symbol-based feed-partitioning scheme. The customized market-data output feed is transmitted from the MDPD to a downstream device.

  • Patent number: 11508890
    Abstract: A display device includes a plurality of light emitting diodes (LEDs) having walls that extend through a transparent semiconductor layer and beyond the surface of the transparent semiconductor layer. Each of the walls surrounds at least part of each of the plurality of LEDs to collimate the light emitted by the plurality of LEDs. In some embodiments, the walls collimate the light emitted by the LEDs by reflecting the light or absorbing a portion of the light. The display device may further include an array of optical lenses that faces the surface of the transparent semiconductor layer to further collimate the light emitted from the LEDs.

The method includes creating a digital representation of the first real-world object and assigning local attributes to one or more portions of the digital representation corresponding to elements of the first real-world object. The method includes obtaining an image of an updated configuration of the first real-world object and transmitting, to the data processing system, the image of the updated configuration. The method includes creating, by the data processing system, a digital representation, of the updated configuration. The method includes comparing, by the data processing system, the digital representation of the first real-world object and the digital representation of the updated first real-world object to identify rearranged parts and assign local attributes.
