  • Publication number: 20250071128
    Abstract: Aspects of the present application comprise an edge-based polymorphic network and associated agentless security solutions. Present systems and methods may effectively shapeshift the network through network topology management, node templates, link templates, and network packet manipulation. Using agentless techniques, the network may be reshaped when attacks are detected in a manner that impacts only the attacker, and an agentless color theory security solution may be used to dynamically protect network traffic.

  • Patent number: 12230255
    Abstract: The techniques disclosed herein provide intelligent display of auditory world experiences. Specialized AI models are configured to display integrated visualizations for different aspects of the auditory signals that may be communicated during an event, such as a meeting, chat session, etc. For instance, a system can use a sentiment recognition model to identify specific characteristics of a speech input, such as volume or tone, provided by a participant. The system can also use a speech recognition model to identify keywords that can be used to distinguish portions of a transcript that are displayed. The system can also utilize an audio recognition model that is configured to analyze non-speech audio sounds for the purposes of identifying non-speech events. The system can then integrate the user interface attributes, distinguished portions of the transcript, and visual indicators describing the non-speech events.

  • Publication number: 20240097688
    Abstract: An example frequency converter includes a drift canceling loop with a balanced delay and a linear signal path (e.g., linear with respect to frequency scaling, amplitude modulation, and/or phase modulation). One side of the drift canceling loop includes a fixed delay, and the opposite side includes an adjustable, complementary delay. The adjustable, complementary delay facilitates precision matching of the signal delays on each side of the loop over a range of frequencies, which results in a significant improvement in noise cancelation, particularly at large offsets to the carrier, while permitting the use of a higher noise, but very fast tuning course scale oscillator. The linear signal path from the signal generator to an RF output facilitates modulation of the signal by the signal generator. A modular format is an advantageous embodiment of the invention that includes the removal of the frequency synthesizer's low phase noise reference into a separate module.

  • Patent number: 11883601
    Abstract: A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system in a high flow therapy system. In one embodiment, a nasal cannula includes a base portion defining a first therapeutic gas passageway, a nozzle disposed adjacent said base portion and defining a second therapeutic gas passageway, the first passageway being in gaseous communication with the second passageway and a conduit configured to facilitate sensing that has an inlet side that is independent of and axially spaced apart from an outlet side of the nozzle. The conduit inlet side can extend beyond the nozzle outlet side of the nasal cannula. Additionally, the nasal cannula has a feature adapted to prevent one of the conduit and the nozzle from creating a seal with a user's nare and a feature adapted to prevent one of the conduit and the nozzle from creating a seal with a user's nare.

  • Publication number: 20230240822
    Abstract: A toothbrush system configured to be coupled to an external suction source. The toothbrush system includes a shaft with a main body with a first end and a second end, and a bristle array and a suction port arranged at the second end. The bristle array and the suction port both extend away from the shaft so that an opening of the suction port is proximal to a distal end of the bristle array. The shaft also includes a stem arranged at the first end. The stem includes a passageway that extends through the main body to provide a fluid connection to the suction port, and is configured to be coupled to the external suction source.

  • Publication number: 20230107858
    Abstract: Described herein is an impact device that may be slidably coupled to a wire rope barrier terminal end and, in the event of an impact on or about the terminal end by a vehicle, the impact device is configured to slide or advance along the terminal end wire rope(s) towards a wire rope barrier end and away from a terminal end anchor position. In a further embodiment, a method is described of retrofitting existing wire-rope barrier terminal ends with the device. The impact device may simultaneously (at least to some extent) absorb kinetic energy from the impact as well as redirect the direction of impact along the terminal end wire rope(s) towards, and optionally along, the wire rope barrier itself depending on the extent of impact. The sliding action also knocks over any posts in the direction of errant vehicle travel in an impact.
