Abstract: A computer-controlled method of automatically purging and precooling a hydrogen fuel line prior to transferring hydrogen fuel from a source to a storage tank includes purging moisture from a hydrogen fuel line. The hydrogen fuel line is configured to fluidically couple a hydrogen tanker storage tank and a fueling station storage tank, the hydrogen storage tanker storage tank and the fueling station storage tank configured to store liquid hydrogen. The method also includes pre-cooling the hydrogen fuel line, causing hydrogen fuel to flow through the hydrogen fuel line to re-fill the fueling station storage tank, and expelling residual hydrogen fuel from the hydrogen fuel line when the fueling station storage tank re-filling is complete.

Abstract: A bayonet coupling system includes a bayonet, a bayonet coupler, and a seal. The bayonet includes a bayonet tube configured to enable the flow of hydrogen fuel therethrough, and a flange coupled to the bayonet tube. The seal is configured to surround the bayonet tube and contact the flange along one side of the flange. The bayonet coupler includes a bayonet coupler tube having an inside diameter larger than an outside diameter of the bayonet tube, the bayonet coupler tube configured to receive the bayonet tube and to seal against the flange at the seal. The bayonet coupler is fixedly mounted directly or indirectly to a hydrogen storage tank such that a longitudinal axis of the bayonet coupler is inclined a predetermined angle with respect to horizontal to prevent a substantial thermal gradient from forming at the seal.

Abstract: A drip pan assembly includes an drip pan and a duct body attached to a lower surface of the drip pan. An upper surface of the drip pan at least partially defines a containment area where food drippings are collected/deposited. A bounded air channel extends along a lower surface of the drip pan for directing a flow of convective air along the lower surface.

Abstract: Reflectarray antenna elements, reflectarrays, and a method of operating an antenna element are described.

Abstract: A screen door assembly kit is provided in which all components of the screen door come in a reduced size package, such as a box or bag. The screen assembly kit includes frame members, unions for assembling frame members end to end in linear alignment or in corner alignment to form a rectangular frame, a screen adapted to cover an opening in the rectangular frame, and means for securing the screen to the rectangular frame.

Abstract: Articulating devices for replacing damaged or degenerated weight bearing joints are provided. The devices may have two or more surfaces that articulate against one another that are coated or fully formed of PEEK or similar materials to provide improved wear capabilities while maintaining sufficient strength to operate in a weight bearing capacity.

Abstract: A platform is provided for connecting to two or more Radio Access Networks (“RAN”). The platform includes a session manager that acts as a central resource. The session manager links to the RANs through one or more controllers, a controller being associated with each RAN to enable monitoring of supply and demand for network resources in relation to the two or more RANs in a defined location. The session manager is operable to apply one or more rules for sharing available network resources across the two or more RANs on a real time or near real time basis thereby providing improve network resource utilization across the two or more RANs and for the respective customers of the two or more RANs in the defined location.

Abstract: Techniques are disclosed for implementing dynamic endpoint compliance policy configuration. In one embodiment, a security service is provided that automates endpoint compliance policy configuration. A customer identifies its deployed client security products, and specifies the desired level of security. This security product and level information is used by the security service to generate endpoint compliance policies tailored to that customer's current network and/or security scheme. The security service can incorporate data obtained from early warning services that deliver timely and actionable security alerts into its policy generation process. In this way, the security service can provide endpoint compliance policies that protect its customers' machines from the very latest threats at any moment in time.
