  • Patent number: 12333530
    Abstract: Methods, systems, and devices for data management are described. A datacenter may include one or more servers and an offline key storage system. The datacenter may receive, via a server and from a multi-party computation (MPC) coordinator, a first request to access a key share associated with an MPC node. The server may transmit a second request for the key share associated with the MPC node via a first cross domain communication path to an offline key storage system. The offline key storage system may verify a digital signature included with the second request. The offline key storage system may transmit a response including the key share that is encrypted using an encryption key associated with the MPC node to the server via a second cross domain communication path. The server may transmit a communication including the encrypted key share to the MPC coordinator.

  • Publication number: 20240414004
    Abstract: Methods, systems, and devices for data management are described. A custodial token platform may communicate with a client to support a multi-party computation (MPC) signature for a message. A central coordinator may receive, from the client, a request to sign a message using respective key shares generated by MPC nodes. The key shares may be generated in accordance with an access structure, where the access structure is configured based on a respective set of parameters for the MPC nodes. The central coordinator may transmit a request to execute a MPC signature using a respective key share. The central coordinator may maintain data associated with execution of the MPC signature function by a subset of the MPC nodes using the respective key shares. Additionally, the central coordinator may transmit, to the client, a result of execution of the MPC signature function by the subset of the MPC nodes.

  • Patent number: 10525419
    Abstract: An oil-water separation membrane is described. The oil-water separation membrane comprises a porous metal sheet with a photocatalyst layer on one side and a layer of nanoparticles and a surfactant on the other side. The layer of nanoparticles and surfactant create a superoleophobic and superhydrophilic coating that allows passage of an aqueous phase and rejection of an oil phase. The photocatalyst layer, combined with UV irradiation, enables degradation of organic contaminants in the aqueous phase. The oil-water separation membrane may be used as part of an oil-water separation system, and a filtered water product may be recycled through the membrane to increase the removal of organic contaminants.

  • Patent number: 9994125
    Abstract: Embodiments include a vehicle comprising a seat, a first sensor coupled to the seat for detecting a seat angle, and a processor communicatively coupled to the first sensor and the seat, and configured to output a control signal for correcting the seat angle if the seat angle is not within a predetermined range of values. Embodiments also include a method of correcting a position of a vehicle seat having an occupant seated therein. The method comprises receiving, at a processor, an output detected by a sensor unit coupled to the seat; comparing, using the processor, the output to a predetermined threshold to determine whether an alarm condition exists; if it does, outputting a control signal for correcting the seat position, wherein the sensor unit includes an angular position sensor.

  • Publication number: 20110208286
    Abstract: An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.

  • Publication number: 20100019924
    Abstract: Innovatory electronic system for the position finding of people, animals, and things. It includes a plurality of transceivers and a transmitter, both provided with hardware and software with low power consumption. Transceivers can be interfaced with one another both directly and indirectly on a network, thus providing an “autoforming network”, that creates and expands automatically, which increases the position finding distance of each transceiver so that a generic transceiver interconnected on a network can carry out a specific position finding of the location of a transmitter carried by the thing to be found.

  • Patent number: 4991750
    Abstract: An improved mounting for an extension tube is disclosed for use with a fluid sprinkling apparatus. The fluid sprinkling apparatus has an input orifice communicating with a liquid internal a pressurized container for spraying the liquid through the extension tube. An actuator controls the flow of the liquid from the input orifice to a terminal orifice. A bore is defined in the fluid sprinkling apparatus extending from an outer wall and terminating in a inner wall. The terminal orifice is disposed within the inner wall and axially aligned with the bore. The bore has a plurality of shoulders spaced along the bore from the outer wall to the inner wall for respectively defining a plurality of bore portions. The plurality of bore portions have progressively decreasing diameters from the outer wall to the inner wall for enabling the extension tube to be inserted into the bore and be frictionally retained by at least one of the bore portions.
