Abstract: For deicing an aircraft, a deicing system includes a base, a plurality of motorized wheel assemblies, a proximal deck and a distal deck, and a plurality of articulated arms. The base may have a length along the longitudinal axis that is substantially equivalent to a specified aircraft. The plurality of motorized wheel assemblies is disposed under the base. A movement direction of each wheel assembly is rotatable about a vertical axis. The plurality of articulated arms is disposed on the proximal deck in the distal deck. A shell is disposed on the end of each articulated arm. The plurality of motorized wheel assemblies moves the deicing system adjacent to the aircraft and the plurality of articulated arms each position a shell adjacent to the aircraft.

Abstract: A server cluster quorum disk composed of two or more separate, intercommunicating disk drives or LUNs. The disk drives or LUNs that together compose a quorum disk may be physically separated by significant distances to form a geographically dispersed quorum disk, or may be more closely physically associated to form a distributed quorum disk. In either case, the two or more disk drives or LUNs closely cooperate to provide the virtual quorum disk interface identical to that of a single, currently available quorum disk with the exception that, upon failure of a disk LUN component of a distributed or geographically dispersed quorum disk, the distributed or geographically dispersed quorum disk continues to function without interrupting or degrading the server cluster in which the quorum disk is employed.

Abstract: Method and system for selecting a new cluster owner for a cluster. The cluster includes a plurality of nodes, where one of the nodes is a current owner of the cluster. First, a determination is made that a new cluster owner is needed. Next, a list of candidates is received. A risk dependent owner selection mechanism selects a new cluster owner from the list of candidates based on at least one risk factor of the candidates.

Abstract: A submersible pump system is disclosed which uses a submersible internal combustion engine as the drive means for the pump. The system is ideally suited for use in installations employing conventional submersible pumps driven with electrical motors as an auxiliary or standby system which is designed to be employed during periods when the conventional pumps are inoperable, such as during an electrical power failure. In addition, the system is useful for pumping applications wherein electrical power is not available. The system of this invention comprises a water-tight submersible enclosure having an internal combustion engine mounted therein. A submersible, centrifugal pump is mounted on the exterior of the enclosure, with the drive shaft of the pump extending into the enclosure through a water-tight seal therein and being connected to the output drive of the engine.
