Abstract: A distributed computer-implemented building automation system for supporting applications that interact with building automation devices. The building automation system has a first device and a second device interconnected across a network channel. A common object superclass stored in a computer readable memory defines a plurality of common objects through instantiation such that the common objects have attributes for storing data and have methods for processing stored data. A source object residing on the first device performs a first control method such that a first attribute of the source object is changed. A destination object residing on the second device performs a second control method using the first attribute of the source object. A surrogate object connected between the source object and the destination object has a value for the first attribute and represents the source object on the second device. The second object has access to the value of the first attribute for performing the second method.

Abstract: The present invention is a process-pair resource manager for use in a transaction processing system. The process-pair resource manager includes a concurrent aspect and a serial aspect. The concurrent aspect provides an object-like interface to a protected resource. An application program participating in a transaction accesses the protected resource by passing messages to the concurrent aspect. The concurrent aspect adds a description of each message as well as the result of processing each message to a transaction record. At the conclusion of a transaction, the concurrent aspect passes the transaction record to the serial aspect. The serial aspect then replays the transaction, using the transaction record. If the replay of the transaction is consistent with the transaction as recorded in the transaction record, the serial aspect sends a message to the concurrent aspect voting to commit the transaction. In turn, the concurrent aspect sends a message to the transaction manager forwarding the commit message.

Abstract: Described is a computer system which is coupled to a remote computer via a data communication link. The computer system has a normally closed enclosure and is capable of securing data retained within the system against unauthorized access. The computer system includes an erasable memory element mounted within the enclosure for selective activation to active and inactive states and for receiving and storing a security password when in the active state. A manually operable option switch is mounted within the enclosure. The option switch is operatively connected with the erasable memory element and manually settable by a user of the computer system for setting the erasable memory element to the active and inactive states.

Abstract: A process controller has a processor with an activation controller, an transaction controller and a batch processor. The transaction controller operates in communication with a machine interface for controlling operations of a plant device for overall job sequencing and individual job control. There is automatic communication of various polling and return signals to ensure correct sequencing of mixing operations. The activation controller helps to ensure that the processor controller is configured at all times for correct operation at a particular materials distribution location. The activation controller 2(b) creates a control file and carries out verification operations automatically to ensure that the initially sorted data is correct. The batch processor operates with parallel control and transaction transmission files which are automatically transmitted to a host computer for consolidation. Control data in both the control and transaction transmission files ensure data integrity.

Abstract: An architecture is provided for isochronous access to memory in a system in which a stream of information may be sent to a memory unit. The stream is divided into a plurality of service periods with a specified maximum amount of information in selected service periods, and selected service periods have a first amount of information associated with asynchronous information and a second amount of information associated with isochronous information. In addition to sending a stream of information, a request for isochronous information from the memory unit may be sent. In this case, a stream of the requested information may be received from a memory unit a predetermined number of service periods after the sending of the request.

Abstract: A method, system and computer program product for selectively restricting access to a program function in a computer system having an operating system security mechanism operates via an application programming interface (API) that includes a program function registration API function, an authorization selection API function, and an authorization query API function. In response to a call to the API registration function, the program function is registered in a repository in the computer system. After the program function has been registered, a system administrator can select user authorizations using a software tool that includes calls to the authorization selection API function. The system administrator may select whether a particular user or group of users is authorized to access each registered program function. A programmer can embed a call to the authorization query API function in an application program, which includes or calls the program function.

Abstract: An apparatus for setting up a time/date of a CMOS real-time-clock within a computer system is disclosed. The computer system includes a processor, a memory, an I/O controller and a first parallel port interface. The apparatus uses the first parallel port within the system to set up the CMOS real-time-clock.

The second parallel port interface is connected to the reference real-time-clock through a signal line. The computer system, responsive to a set-up instruction, reads the reference date/time from the reference real-time-clock and writes the reference date/time, via the I/O controller, into the CMOS real-time-clock of the computer system.

Abstract: Disclosed is a combined pass through and load/unload system for automated data storage libraries. Separate portals open into each of the libraries. A pivoting robot supports a housing which is capable of supporting at least one removable multi-cartridge magazine, and pivots about a pivot axis. An actuator withdraws or extends the housing toward or away from the pivot axis. A pass through controller operates the pivoting robot to position the housing at a portal and operates the actuator to extend the housing into the portal so that the library may load and/or unload the data storage media into or out of the removable magazine(s) in the housing. The controller then operates the actuator and robot to withdraw the housing out of the portal. The controller may position the housing at the bulk load/unload position so an operator may unload and/or load magazines from the housing. The controller may position the housing at the portal of the other library to allow the transfer of media thereto.
