Abstract:

The present invention relates to a telephone system including a telephone switch () having at least one incoming line and at least one outgoing line. The telephone switch () is responsive to control signals to switch a call received from a caller to an outgoing line directed to one of a plurality of numbers stored in a database for a first party. An audio processing unit () is connected to the telephone switch () to receive incoming audio communications from the caller and to provide outgoing audio communications to the caller. A control unit () controls the telephone switch to transfer the call to the at least one outgoing line. A method of providing telephone communication service to a user is also provided. The method included the steps of receiving an incoming call from a user, connecting the incoming call to an audio processing unit, and obtaining a first audio request from the user. The method also includes the steps of determining whether the first audio request corresponds to one of a plurality of parties stored in a database, and placing an outgoing call directed to the one of the plurality of parties.

Abstract:

This invention relates to an arrangement for distributing interrupts within a multiprocessing system and for processing personal computer (PC) interrupts as well as multiprocessor interrupts in that system. New interrupts are diverted from processors that have recently processed an interrupt, thus preventing any one processor from being overloaded with an interrupt processing work load. Some of the processors are equipped to process PC interrupts and multiprocessing system interrupts. In each processor classes of interrupts may be masked out. A distributed arbitrator is used to allocate an interrupt among a plurality of processors available to process the interrupt.

International Classification:

Abstract:

A single sign-on server associated with a single sign-on client authenticates a user of a device. Subsequent to the authenticating, the single sign-on client receives a request for an authentication token from a single sign-on enabled application operating on the device. The single sign-on client determines whether an application lock flag for the single sign-on enabled application is set. Responsive to the determining, the single sign-on client provides the authentication token to the single sign-on enabled application when the application lock flag is not set and withholds the authentication token from the single sign-on enabled application when the application lock flag is set.
