Abstract: A supercharger having twisted meshing rotors sealingly contained within a housing having an inlet port to admit air into the meshing rotors and an outlet port to expel air from the meshing rotors, the rotors having mesh points where the rotors contact one another and spaces between their mesh points to accept air from the inlet port and propel it to the outlet port as the rotors are rotated and the mesh points travel axially, the housing, inlet and rotors defining an angle known as the seal transfer angle which is greater than or equal to zero degrees when the inlet port is closed and the volume of air between rotors is sealed and has no leakage path. In the described supercharger the housing, rotors and inlet port are configured to have a negative seal transfer angle of, e.g., ?10 to ?40 degrees or more, up to the maximum available, and to provide a leakage path for an angular portion of the rotors' rotation, improving high end performance without degrading low end performance.

Abstract: A charge air cooler, e.g., as used with a supercharger having meshing rotors in sealing contact with a housing, the housing having an inlet port to admit air into the meshing rotors and the housing having an outlet port to expel air from the meshing rotors, the charge air cooler having an inlet-side core for transmitting the flow of pressurized air, and an outlet-side core receiving the flow of pressurized air transmitted from the inlet-side core and further transmitting the flow of pressurized air, each core having coolant conduits and fins joined to the coolant conduits for contact with the flow of pressurized air, the fins being arranged with a predetermined density, wherein the inlet-side core fin density is lower than the outlet-side core fin density, whereby the inlet-side core presents less resistance to the flow of pressurized air than the outlet-side core and the outlet-side core presents greater surface area for heat conductance from the flow of pressurized air than the inlet-side core.

Abstract: A method for an automated call distribution system to re-associate a caller with a queue position previously established in an on-hold queue. The method includes receiving a first incoming call from a caller and assigning the caller to a position in an on-hold queue when the caller is placed on-hold by the automated call distribution system. A placeholder for the caller may then be assigned in the on-hold queue when the caller disconnects with the automated call distribution system. The placeholder corresponds to the position of the caller in the on-hold queue and is associated with a caller identifier. The method further includes receiving a second incoming call from the caller and associating the second incoming call with the caller identifier. It is then determined that the caller is associated with the placeholder. The caller is placed back into the on-hold queue at the position of the placeholder.

Abstract: One example embodiment includes a method for providing multi-tenancy in a computing environment. The method includes receiving a script in a computing environment, where the script includes one or more actions to be completed by the computing environment. The method further includes providing one or more computing resources in the computing environment and building an action list for the one or more computing resources, where the action list is a data structure that contains a list of one or more actions to be executed by the one or more computing resources. The method further includes transmitting a first action to one of the one or more computing resources, where the first action is one of the one or more actions. The method further includes executing the first action in the one of the one or more computing resources and indicating to the action list the completion of the first action.

Abstract: One example embodiment includes a method for compiling one or more scripts on a per-action basis. The method includes receiving a script including one or more actions to be accomplished by a script application. The method further includes determining if the script has been previously compiled and determining if the script has been changed since it was last compiled. The method further includes retrieving the compiled script from a memory if the script was previously compiled and if the script has not been changed since it was last compiled. The method further includes compiling the script if it has not been previously compiled or if the script has been changed since it was last compiled. Compiling the script includes translating the script from source code to machine code, saving the machine code to the memory and identifying the script as compiled. The method further includes executing the compiled script.

Abstract: One example embodiment includes a method for computing environment redundancy with check pointing. The method includes receiving a script application in a first computing environment and a second computing environment. The method further includes receiving the one or more scripts in the first computing environment and the second computing environment. The method further includes executing the script application and at least one of the one or more scripts in the first computing environment and preparing a snapshot of the state of the first computing environment at predetermined checkpoints in the script application and the one or more scripts. The method further includes saving the snapshot to a memory in the first computing environment, transmitting the snapshot to the second computing environment and saving the snapshot to a memory in the second computing environment.

Abstract: An Internet search engine is disclosed. The search engine is capable of producing relevant search results in a ranked order, which is at least partially determined by the web site providers themselves. The search engine is preferably fee-based and policed to provide relevant search results to the end user.

Abstract: An improved method and system for initializing the logical units (LUs) in a Gateway between an SNA network having a mainframe host computer and another network. An activation procedure derives the Table of Boundary LUs on the mainframe host computer by noting the device logical unit numbers within the set of ‘Activate Logical Unit’ (ACTLU) SNA Request Units. If the mainframe host computer includes an LU in its Table of Boundary LUs, then the activation procedure creates a corresponding LU in the Gateway. The activation procedure also marks each of the created LUs in the Gateway as active. The newly created LUs are then added to the resource pool of LUs available to the network. Additional aspects include a method for assigning a logical unit type to an LU based upon whether a Bind request is received from the mainframe host computer within a certain amount of time after sending a positive sense code to the mainframe host computer.
