  • Publication number: 20260149621
    Abstract: A system and method to configure a high-speed interconnection network between devices coupled to a host is disclosed. A bus having a plurality of lanes is coupled to the host. Each of the devices are coupled to one or more of the lanes of the bus allowing communication to the host. Each of the devices is coupled to two neighboring devices via cables coupled to high-speed input output ports to form a ring interconnection between the devices. The devices are identified by designating a first device and sending packets to the other devices to identify the other devices to allow high speed data traffic to be sent between the devices on the ring interconnection.

  • Publication number: 20200153808
    Abstract: Embodiments of systems and methods disclosed herein include an embedded secret provisioning system that is based on a shared-derivative mechanism. Embodiments of this mechanism use a trusted third-party topology, but only a single instance of a public-private key exchange is required for initialization. Embodiments of the system and methods are secure and any of the derived secret keys are completely renewable in untrusted environments without any reliance on asymmetric cryptography. The derived secrets exhibit zero knowledge attributes and the associated zero knowledge proofs are open and available for review. Embodiments of systems and methods can be implemented in a wide range of previously-deployed devices as well as integrated into a variety of new designs using minimal roots-of-trust.

  • Publication number: 20050274824
    Abstract: Disclosed is a pneumatic liquid nutrient dispensing assembly for hydroponically cultivated plants. The assembly includes a reservoir and a liquid nutrient dispenser disposed within the reservoir. The liquid nutrient dispenser includes a substantially coaxial pump body with inner and outer tubes forming a distribution end having a distribution hub and an inlet end having a liquid intake structure. Airflow in an annular duct formed between the walls of the coaxial tubes enters the inner tube through an annular passage and carries liquid nutrient within the inner tube to the distribution hub. Distribution members fluidly connected to the distribution hub direct a flow of liquid nutrients and air to one or more plants.
