Methods and systems are provided for adjusting a fuel injection split between a direct injection and a port injection based on engine vacuum demand. When more intake manifold vacuum is required, relatively more direct injection is used to take advantage of the associated throttling for generating vacuum. The vacuum may then be used for canister purging, crankcase ventilation, or actuating an engine vacuum consumption device.

A load-balancer assigns incoming requests to servers at a server farm. An atomic operation assigns both un-encrypted clear-text requests and encrypted requests from a client to the same server at the server farm. An encrypted session is started early by the atomic operation, before encryption is required. The atomic operation is initiated by a special, automatically loaded component on a web page. This component is referenced by code requiring that an encrypted session be used to retrieve the component. Keys and certificates are exchanged between a server and the client to establish the encrypted session. The server generates a secure-sockets-layer (SSL) session ID for the encrypted session. The server also generates a server-assignment cookie that identifies the server at the server farm. The server-assignment cookie is encrypted and sent to the client along with the SSL session ID. The Client decrypts the server-assignment cookie and stores it along with the SSL session ID. The load-balancer stores the SSL session ID along with a server assignment that identifies the server that generated the SSL session ID. When other encrypted requests are generated by the client to the server farm, they include the SSL session ID. The load-balancer uses the SSL session ID to send the requests to the assigned server. When the client sends a non-encrypted clear-text request to the server farm, it includes the decrypted server-assignment cookie. The load balancer parses the clear-text request to find the server-assignment cookie. The load-balancer then sends the request to the assigned server.

A system allowing for the active management of aerostatic lift in buoyant and semi-buoyant aerial vehicles comprised of a high tensile-strength outer pressure cell of a given volume and an inner compression cell of only slightly smaller dimensions. The inner compression cell is filled with a lifting gas, such as helium or hydrogen, to some fractional volume of its maximum, allowing for expansion of the lifting gas at different operational altitudes. When a reduction in aerostatic lift is desired, external air is compressed through the use of air handling means, and introduced into the outer pressure cell through a directional valve that prevents the pressurized air from leaving the pressure cell. When increased aerostatic lift is once again desired, the valve system may release all or a part of the pressurized air in the pressure cell, allowing the lifting gas to expand thereby displacing a greater volume of air and increasing lift.
