  • Publication number: 20250283227
    Abstract: A plasma-bubble reactor, reactor system and method for producing hydrogen peroxide (H2O2), one or more hydrocarbon(s), and syngas is disclosed. The reactor comprises a vessel configured to hold a liquid; and a plasma generating means, in association with the vessel, configured to receive an input feed comprising carbon dioxide (CO2) gas and generate a plasma from the CO2 gas to produce an activated CO2 gas encapsulated within a plurality of bubbles formed in the liquid, wherein the activated CO2 gas reacts with water (H2O) at a plasma-liquid interface formed between the bubbles and the surrounding liquid to produce hydrogen peroxide (H2O2), one or more hydrocarbon(s) and syngas.

  • Publication number: 20240340100
    Abstract: A system for achieving Precision Time Protocol (PTP) redundancy and load balancing across a set of active time servers deployed in a cluster is disclosed. The system may organize a set of PTP Grandmasters (GMs) (e.g., located in a datacenter) into a plurality of PTP clusters (e.g., for load balancing). A set of PTP ordinary clocks (OCs) (e.g., time clients) may be grouped in OC Groups and then into PTP clusters for GM assignation, wherein each PTP OC includes a unicast master table (UMT) that includes one or more potential PTP GM port addresses and priority values. Based on a Master Clock Mechanism, one of the potential GMs may be selected based on one or more PTP GM priority attributes.

  • Patent number: 11939220
    Abstract: Described is a method of preparing transition metal nanoparticles on a graphene support, in which a tertiary graphite intercalation compound is provided with intercalated metal ions such that the tertiary graphite intercalation compound comprises a graphene sheet having a negative charge. The graphene sheet is contacted with a transition metal salt to cause reduction of the transition metal salt by the graphene sheet, and to form transition metal nanoparticles. Also described are products arising from the method, and uses of those products.

  • Publication number: 20060287686
    Abstract: A system, method, and implantable pulse generator (IPG) device that stores, on the implantable device, two or more treatment-protocol stimulus programs, each preferably having one or more stimsets, preferably as prescribed by a physician. The IPG communicates with an external patient programmer (EPP) to determine which of the stimulus programs should be run at any given time. Programs stored on the IPG are uploaded to the external device, and a selected program retransmitted (either the program itself, or selection information identifying the selected one of the IPG-stored programs) to the IPG for execution. An advanced programmer is used to read and write program instructions to the IPG. In this way, the patient is capable of carrying two or more program options with him, and if the patient uses an EPIPG, he can use any available EPP to power and operate the EPIPG.

  • Publication number: 20060030204
    Abstract: Disclosed are systems and methods which provide a header assembly for interfacing a medical device with a lead, wherein the header assembly includes a strain relief portion integral thereto. The strain relief portion may be adapted to facilitate a user visually verifying when a lead has been fully inserted into the header. Structure, such as a band or ring, may be provided upon the strain relief portion in order to provide a readily identifiable visual aid for determining when a lead is fully inserted.

  • Publication number: 20050004622
    Abstract: A system, method, and implantable pulse generator (IPG) device that stores, on the implantable device, two or more treatment-protocol stimulus programs, preferably as prescribed by a physician. The IPG, whether it is a self-contained implantable pulse generator (SCIPG) or externally-powered implantable pulse generator (EPIPG), communicates with an external patient programmer (EPP) to determine which of the stimulus programs should be run at any given time. An advanced programmer is used to read and write program instructions to the IPG. In this way, the patient is capable of carrying two or more program options with him, and if the patient uses an EPIPG, he can use any available EPP to power and operate the EPIPG.
