  • Publication number: 20240299683
    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.

  • Publication number: 20180076757
    Abstract: A solar energy tracking assembly for a solar energy panel can include a frame that supports the solar energy panel and pivots the solar energy panel between a retracted position generally parallel to a support surface on which the tracking assembly rests and an upright position. The frame can include a circular track on which the solar energy panel rotates about an axis of the circular track. The circular track is supported by a combination of support beam and footings that both bear the force of the solar panel as well as bear the torsional force from wind loading on the solar panel.

  • Publication number: 20110146913
    Abstract: An industrial fabric used in the manufacture or processing of at least one material web includes a base fabric having a board side and a machine side. The base fabric includes a plurality of spirals extending in a cross machine direction (CMD). The spirals are interconnected together with each other along adjacent peripheral edges to form a spiral link fabric. The base fabric has opposite lateral side edges extending in a machine direction (MD). One or more electrostatic control yarns are positioned within a corresponding spiral and extend in the CMD direction to the lateral side edges. A pair of conductive edge coatings are applied to at least the board side of a respective lateral side edge for a predetermined width. The conductive edge coatings and the one or more electrostatic control yarns form an electrostatic grid.

  • Patent number: 7896034
    Abstract: A fabric for supporting a fibrous web is disclosed. The fabric has a layer that includes a plurality of weft yarns and a plurality of warp yarns interwoven with the plurality of weft yarns. The warp and weft yarns define a web-facing side and an opposite machine-facing side. The warp yarns include at least one of polyphenylene sulfide (PPS) and polyetheretherketone (PEEK). In addition, a yarn count, weave pattern, and yarn shape of the fabric are configured such that molten polymer drops are scrapable from the web-facing side leaving an upper support surface that does not blemish a fibrous web supported by the fabric.

  • Publication number: 20080098006
    Abstract: A system for accessing, by a resource, a setting in a virtualized user profile includes an isolation environment, a resource, and a filter driver. The resource executes outside an isolation environment on a local machine and requests access to a setting in a user profile. The filter driver intercepts the request for access and identifies one of the isolation environment and a remote machine, responsive to an application of a rule to the request. The filter driver redirects the request to the one of the isolation environment and the remote machine. A method includes intercepting an instruction from a resource to modify a setting on a local machine, the resource provided by a local machine and executing outside of an isolation environment. The method includes identifying the isolation environment, responsive to an application of a rule to the instruction. The method includes redirecting the instruction to the isolation environment.

  • Publication number: 20050050317
    Abstract: The present invention features a system and method for establishing a secure communication channel between a client and an application server. In one embodiment, a ticket service generates a ticket having an identifier and a session key. A communications device obtains the ticket from the ticket service and transmits the ticket to a client over a secure communication channel. The client transmits the identifier of the ticket to an application server over an application communication channel. The application server then obtains a copy of the session key of the ticket from the ticket service. Communications exchanged between the client and the application server over the application communication channel are then encrypted using the session key to establish the application communication channel as a secure communication channel.
