Embodiments of a system and method for providing class dependency graph-based class loading and reloading may be used to segregate namespaces in a graph-centric way, and may provide a set of normalized topologies that may be used to efficiently support hot-swapping of programmatic logic such as classes, applets, and beans, among other applications. Embodiments may provide a domain-independent, flexible and robust namespace segregation technique that is based on the dependency between the various classes and not on details like the roles the classes play. The problem of segregating namespaces is formulated as a graph theory problem, and a solution is sought through graph techniques. The graph may be normalized by identifying and grouping interdependent classes and non-interdependent classes in separate groups. A directed dependency relationship of the groups may be determined using the relationships between the member classes of the groups.

The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. The refillable system comprises a hydrogen fuel source refiner that includes the mating connector and provides the hydrogen fuel source to the storage device. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision to the receiving device for a limited time.

A method and system for replacing a device driver during system operation provides for hot-swapping device drivers without shutting down a device driver stack. Particularly useful with file system and file storage devices, the method and system utilize a shell device driver that replaces the physical device driver's entry point interface. The shell device driver has a device driver side interface that calls the physical device driver in response to operating system requests. When an update of the physical device driver is requested, either by an operating system utility or a special upgrade application, the shell device driver receives an update indication. The shell device driver can then finish required tasks, uncouple and unload the existing physical device driver and couple to the new device driver without disrupting the operating system device interface.

A disposing structure of industrial computer chassis includes a chassis shell, two motherboard trays and a back plate. The interior of the chassis shell is divided into a storage unit section and a motherboard section. The interior of the storage unit section is arranged at least one storage unit, while two motherboard trays are disposed in the motherboard section. The interior of each motherboard tray is arranged a motherboard. In the motherboard trays, at least one motherboard tray is extended a wedge frame toward the storage unit section. A transfer card having a hot swapping function is arranged on the wedge frame and is arranged by inserting into the corresponding motherboard. In addition, a back plate is arranged between the storage unit section and the motherboard section. Corresponding to the wedge frame, a slot capable of a hot swapping function is arranged on the back plate. In so doing, the transfer card may be inserted into the slot, thereby, providing a hot swapping function.

A removable fan bay for a computer system or information handling system is provided that permits the hot swapping of individual fans of the fan bay. The removal of the fan bay enclosures results in the removal of all of the fans of the fan bay. The fan bay is held in place by a securing mechanism that includes a latch and a receiving bracket. The latch includes a retractable handle. When the handled is placed in the raised position, a shoulder in the latch disengages from the receiving bracket, permitting the latch to be released from the receiving bracket and permitting the fan bay to be removed from the chassis of the computer system.

Packaging a hot-swappable server module (server blade) in a computer network appliance with shared, hot-swappable power, network, and management modules to provide highly available computer capacity. Distributing power between hot-swappable modules using single DC input voltage.

Improved techniques for rendering a peripheral device removable (e.g., unpluggable) are disclosed. According to one aspect of the invention, the peripheral device is rendered removable from a host computer without preparatory user actions. In effect, the peripheral device can be automatically prepared for removal in the event that its user removes (unplugs) it from its host computer. According to another aspect of the invention, the peripheral device includes a data storage device that is mounted to a file system of the other computer when the other computer desires access to the data storage device. Otherwise, the data storage device is normally unmounted so that if the peripheral device were to be removed (e.g., unplugged) no harm or damage to data stored therein would occur. These aspects of the invention can be utilized alone or in combination with one another. The invention is particularly well suited for peripheral devices that are media players which are “hot” unpluggable without detrimental consequences.

A hot swappable system is described. It included software controlled hot swapping operations which provided a graceful booting or power-down of the system. In the even of force insertion or extraction of the system blades, a set of hardware features (such as using different pin lengths in the connectors and dampening resistor) prevents these types of operations from damaging the system hardware or affecting the operation states of other blades within the system.

A system and technique for detecting data errors in a memory device. More specifically, data errors in a memory device are detected by initiating an internal READ command or verify operation from a set of logic which is internal to the memory system in which the memory devices reside. Rather than relying on a READ command to be issued from an external device, via a host controller, the verify logic initiates verify routine in response to an event such as an operator instruction, hot-plug operation, or a periodic schedule. By implementing the verify operation, the system does not rely on external READ commands to verify data integrity. The verify routine may rely on typical ECC error logging mechanisms and may be used in a RAID memory architecture. Further, the verify routine may be used in conjunction with other error logging and correction logic, as well as scrubbing logic.

A device for controlling an actuator includes an input interface that receives a plurality of input signals including a setpoint command signal and a feedback signal. An output interface provides a drive signal to the actuator. First, second, and third redundant loop controllers processes the setpoint command signal and the feedback signal to generate respective actuator control signals. A primary controller compares the actuator control signals to determine whether at least two are substantially similar. The device outputs the drive signal to the actuator according to an actuator control signals that has been determined by the primary controller to be substantially similar to another. Any one of the redundant loop controllers is hot swappable with a replacement loop controller such that loop controller redundancy is operatively maintained by the device in controlling the actuator while one of the redundant loop controllers is hot swapped.
