Abstract: A virtual machine hosting environment executing on a physical machine is operable to instantiate a virtual machine that is capable of initiating I/O operations directed to a remote storage. The virtual machine hosting environment is operable to determine when an unavailability condition exists with respect to the remote storage and when such unavailability condition no longer exists. The virtual machine hosting environment is further operable to suspend the virtual machine based at least on the determination that the unavailability condition exists and to resume the virtual machine based at least on the determination that the unavailability condition no longer exists. The virtual machine hosting environment may be still further operable to save one or more pending I/O requests generated by the virtual machine in conjunction with pausing the virtual machine and to send the pending I/O request(s) to the remote storage in conjunction with resuming the virtual machine.

Abstract: An ophthalmic tool includes an ophthalmic speculum for holding a patient's eye open and for guiding a lens probe of an eye imaging device to be directly contacted with a cornea of the patient's eye. The ophthalmic speculum includes two eyelid distensible frames, a mechanism to spread the eyelid distensible frames apart, and a probe guiding frame including a plurality of probe guiders spacedly extended from the eyelid distensible frames. Each probe guider has a peak upwardly extended above the eyelid distensible frame that serves as a guiding point and forms a probe guiding cavity within the guiding points of the probe guiders. The lens probe is guided to be disposed within the probe guiding cavity via the guiding points before and after the lens probe is aligned and contacted with the cornea of the patient's eye in a proper upright orientation.

Abstract: A crucible handling shuttle includes a pair of opposed dual crucible-gripping arms mounted on a rotatable head. The shuttle is removably plugged into a sliding block of a carriage to move between a furnace and a crucible loading station. The carriage includes mechanical, electrical, and pneumatic plugs or sockets which couple to mating sockets or plugs of the shuttle. A linear actuator extends between the carriage and the furnace base to raise and lower the carriage and shuttle coupled thereto.
