Abstract: A combined hinge pin hanging device, for hanging items at inside corners, at outside corners, and on flat wall surfaces includes: a first member, elongated, straight, generally cylindrical, and of a predetermined length, consisting of a continuous first diameter, for placement securely within an axial continuous passage formed collectively within knuckles of interleaved hinge leaves, thereby to secure as a hinge pin; a second member, elongated, generally cylindrical, and not continuously straight, of a second diameter, the first and second members coupled, and the second member extending upwardly from a top of the first member, the second member also consisting of at least one portion that extends outwardly away from an axial line of the first member upon which to hang an item; and a stop defined between the first and second members to prevent the device from entry beyond the stop into the axial continuous passage.

Abstract: A method for simulating the insertion of a data storage medium into or removal of a data storage medium from an input/output station, alternatively referred to as an import/output station. In one application of the invention, a data storage resides in an I/O station slot. A first variable corresponding to this slot is modified to indicate that the slot is actually empty. A command is issued indicating that the I/O station has been accessed, triggering a scan of the slot by an automated robotic accessor. Since the accessor will detect that the slot is, in fact, full, it will report this status to a library manager which will, in turn, update the first variable. The action of updating this variable is reported to associated devices such as a host computer, host application, or other associated device. In this manner, the operation of the library manager and devices receiving status information may be tested without requiring that a physical data storage medium actually be removed and re-inserted.

Abstract: A method for assigning element addresses in an automated data storage library includes determining if a data storage device, such as a tape cartridge, belongs to a particular host's cartridge assignment policy. If so, the data storage device is issued a virtual import/export element address taken from a set of non-common virtual import/export element addresses, if available. If no non-common address is available, then a common virtual import/export element address is assigned to the data storage device. If no addresses, either common or non-common, are available, then the data storage device is queued until an address becomes available.

Abstract: An apparatus, system, and method are disclosed for managing physical addresses of data storage media within a data storage library. The library maintains a data table of storage slots and the media stored in those slots. The data table may contain addresses for storage slots that are not physically present or accessible within the library. Hardware such as storage slots may be added or removed without causing an inconsistency within the data table of assigned addresses. Addresses may be recorded as the particular frame, column, and row that describe the location of a particular storage slot. Each data storage media is associated with a particular host. The data table of the library maintains a record of data storage media and the host affinity the media corresponds to.

Abstract: A storage subsystem, method of automatically maintaining the subsystem hardware configuration up to date and program product therefor. The storage subsystem automatically initiates hardware discovery in response to a triggering event. Subsystem hardware information is collected during hardware discovery and checked against a current configuration to identify hardware changes. Whenever hardware changes are identified, the subsystem configures the hardware and calibrates newly configured hardware. So, hardware changes may be automatically discovered, configured and calibrated free from operator intervention.

Abstract: Disclosed is a method, system, and program for using storage slots efficiently. A storage element count is assigned to each one of multiple logical libraries, and the sum of the storage element count for each one of the multiple logical libraries exceeds the total number of storage slots in the library.

Abstract: Disclosed are a system, a method, and a computer program product to provide improved error handling in an embedded system. When the embedded system encounters a fatal error, information pertaining to the error is saved and an indication that the error has occurred is also saved. The embedded system resets itself to allow normal operation to resume. Before or after the reset, the embedded system sets an indication of the prior error so that a human or a machine will be alerted to the fact that the embedded system had encountered the error. At some point in time, the error information may be retrieved, collected or sent for post error analysis. The error flag and/or error status is then cleared to remove the current error condition and/or allow a subsequent error to be managed.

Abstract: Disclosed are a system, a method, and an article of manufacture to provide for configuring an automated data storage library having one or more storage frames that operate with different types of data storage media. The automated data storage library is configured to operate with sequential storage shelf addresses assigned to consecutive storage frames that use the same type of data storage media. The storage frames that operate with different types of data storage media may be physically assembled in any order. The automated data storage library may be expanded by attaching storage frames that operate with different types of data storage media in any order while maintaining sequential storage shelf addresses that span across multiple library frames.

Abstract: Disclosed is a method, system, and program for using storage slots efficiently. A move command is received to move a portable data storage medium from a source address to a destination address. An empty storage slot that has no association with the destination address is located. The portable data storage medium is moved from the source address to the located empty storage slot. An association is stored between the located empty storage slot and the destination address.

Abstract: Systems and methods for cleaning and operating gas cleaning devices using vibration generators wherein the systems include sensors and programs for monitoring and predicting resonant conditions of different surface areas and zones in order to vary the frequency and amplitude of vibrations to establish optimum resonant conditions on such surface areas or zones and thereby optimize cleaning and operation of such gas cleaning devices.

Abstract: In an electrostatic precipitator system powered by a primary power source, the power supply has a converter and a high voltage device. The converter can be coupled to the primary power source for producing a converter voltage with a different frequency content. The high voltage device is driven by the converter, producing from its converted voltage a high voltage. This high voltage is influenced by the different frequency content, having at least one frequency component at a predetermined low frequency which is sized to promote efficient precipitation.
