  • Patent number: 12129439
    Abstract: The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; recovering at least part of the raw synthesis gas from the gasification zone and supplying at least part of the recovered raw synthesis gas to a partial oxidation zone; equilibrating the H2:CO ratio of the raw synthesis gas in the partial oxidation zone to obtain equilibrated synthesis gas; recovering at least part of the equilibrated synthesis gas from the partial oxidation zone and treating the gas to remove impurities and generate a fine synthesis gas; optionally adjusting the H2:CO ratio of at least part of the fine synthesis gas to obtain adjusted fine synthesis gas; and converting the optionally adjusted fine

    Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user.

  • Patent number: 11821202
    Abstract: A prefabricated concrete form with vertical spacers between fill forming cladding with cut-outs in the spacers having horizontal rebar received therethrough and received therein. Stand-offs are provided between the vertical spacers with vertical rebar received on the stand-offs. In one version, the stand-offs are attached to the horizontal rebar. In other versions, the stand-offs are attached to the spacers. A cut-out is formed in one of the claddings to form an auxiliary fill space on the outside of the cladding, which when filled with concrete, upon hardening, forms a ledge for supporting a stair structure.

  • Publication number: 20230318998
    Abstract: A system of communicating data to and between a client device in a residence and a utility network is provided. The system includes a proxy controller located at the residence and a first network configured to transmit and receive data between a central controller associated with the utility network and the proxy controller. The system further includes a second network configured to transmit and receive data between the proxy controller and the client device in the residence. The proxy controller is operative to receive data from the client device over the second network, aggregate the received data in a predefined format, store the aggregated data within the proxy controller, and send the aggregated data to a central controller over the first network.

  • Publication number: 20230315037
    Abstract: Power grid management systems and methods include determining a power reference, and sending a first message from a first controller to each of a plurality of second controllers based on the power reference. Each of the plurality of second controllers is configured to control a plurality of associated distributed energy resources (DERs). Energy usage of the associated DERs is modified by each of the plurality of second controllers based on the first message. Each of the second controllers sends feedback data to the first controller message based on the modified energy usage of the associated DERs. The feedback data is aggregated by the first controller, and the aggregated feedback data is compared to the power reference. The first controller sends a second message to each of the plurality of second controllers based on the comparison.

  • Patent number: 11323431
    Abstract: A technique for providing access to protected resources uses personal authentication tags (PATs) and enforces a requirement that a workstation sending an authentication request be trusted by a server that receives the request. Accordingly, the server allows an authentication request to proceed only when the request is received from a workstation having a trust relationship with the server. Otherwise, the server denies the authentication request. By restricting PAT-type authentication requests to trusted workstations, risks posed by malicious users are greatly reduced.

  • Patent number: 11297505
    Abstract: A system identifies whether a mobile device is compromised. The system includes mobile devices, a communication network, and a server. Each mobile device includes a processor, a power supply, and a network interface. The processor executes an operating system and applications including a monitor application. The power supply indicates the power consumed by the mobile device during executing the operating system and the applications. The network interface transfers information to and from the mobile device via a communication network. This transferred information includes logs securely collected by the monitor application. The logs can include a log of the system calls, a log of the power consumed, and a log of network activity. The server receives the logs from the mobile devices and generates a correlation among the logs, and the server identifies at least one mobile device that is an outlier in the correlation as a compromised mobile device.

  • Patent number: 10626753
    Abstract: A pulsed pressure, heat recovery system includes a pressure vessel for holding a vaporisable first fluid. The vessel contains a heat exchanger, and provides communication to the heat exchanger for flow of a heated second fluid. The heat exchanger enables heat transfer from the second fluid to vaporise the first fluid. The system also includes a flow loop for the first fluid extending from an outlet of the vessel to an inlet to the vessel, having in series: a first non-return valve, a turbine and a second non-return valve. The first non-return valve allows the vaporised first fluid to flow from the vessel to the turbine when the pressure of the vaporised first fluid in the vessel exceeds a predetermined limit. The turbine extracts energy from expansion of the vaporised first fluid. The second non-return valve prevents flow reversal around flow loop between the turbine and the inlet.

  • Patent number: 10439799
    Abstract: Indirect fire protocol according to several embodiments of the present invention can include the initial step establishing a grid and locating a forward observer (FO) and a firing unit (FU) in the grid. The FO can estimate the bearing and range to a High Value Target (HVT) within the grid, and can homomorphically encrypting said HVT estimated position data. FO can then transmit the encrypted HVT estimated position data over cloud network architecture to a Fire Direction Center (FDC), using the FDC's Keypublic. The FDC can outsource the calculation of an absolute position of said HVT in said grid to non-secure internet cloud architecture, but with encrypted HVT estimation data and the FO position data in the grid (which the FDC knows). Once calculated, the HVT encrypted absolute position data can be decrypted, and then transmitted from FDC to a FU, using the FU's Keypublic.

  • Patent number: 9247396
    Abstract: In a wireless multihop network having node devices within communication range neighboring node devices in a corresponding local neighborhood, the node devices initiate repeated message broadcasts of a first message as a connection-less broadcast into the local neighborhood. Initiation of message broadcasts is governed such that the message broadcasts are permitted only at specified transmission times within a plurality of transmission time windows. Each of the node devices determines whether any of the connection-less-broadcasted messages are duplicates of the first message, and generate a count of those duplicates received during each of the transmission windows. Based on counts of the duplicates, initiation of a message broadcast of the first message in a current transmission window is suppressed in response to a corresponding count of duplicates of the first message received during the first transmission window exceeding a suppression limit.
