To store an input string of M N-tuples of bits, a substitution transformation is selected in accordance with the input string and is applied to the input string to provide a transformed string of M N-tuples of bits. M or more memory cells are programmed to represent the transformed string and preferably also to represent a key of the transformation. Alternatively, the memory selectively programs each of M or more cells to a respective one of 2N states. A mapping that maps the binary numbers in [0,2N−1] into respective states is selected in accordance with the input string and is used to program M cells to represent the input string. Preferably, a key of the mapping is stored in the memory in association with the M cells.

An apparatus, system, and method are disclosed for authenticating users through multiple communication channels. The authentication method of the present invention may be used to supplement password systems or replace password authentication, effectively enabling secure sharing, auditing, delegation, and revocation of authority.

A cargo latch is provided for use in restraining objects such as containers, pallets and the like, against movement with respect to a floor of a cargo hold, in particular the cargo hold of an aircraft. The latch comprises a frame with a shaft disposed therein and a base, a lower end of which is rotatably mounted on the shaft. The base can therefore pivot with respect to the frame. At least one restraining hook is pivotally mounted to an upper end of the base.

A replicated decentralized storage system comprises a plurality of servers that locally store disk images for locally running virtual machines as well as disk images, for failover purposes, for remotely running virtual machines. To ensure that disk images stored for failover purposes are properly replicated upon an update of the disk image on the server running the virtual machine, a hash of a unique value known only to the server running the virtual machine is used to verify the origin of update operations that have been transmitted by the server to the other servers storing replications of the disk image for failover purposes. If verified, the update operations are added to such failover disk images.

If verified, the update operations are added to such failover disk images. To enable the replicated decentralized system to recover from a failure of the primary server, the master secret is subdivided into parts and distributed to other servers in the cluster. Upon a failure of the primary server, a secondary server receives a threshold number of the parts and is able to recreate the master secret and failover virtual machines that were running in the failed primary server.

A method and system for maintaining a high reliability logical connection between hosts employs adaptive transparent pinging, clone blocking and bandwidth leveling to realize improvements in the areas of connection status verification, security and bandwidth management. In adaptive transparent pinging, a ping interval that defines a frequency at which ping messages are transmitted from an initiating host to a receiving host to check connection status is dynamically regulated based on data indicative of the reliability of a connection. In clone blocking, the receiving host verifies that a new connection that appears redundant is a re-established connection from the initiating host rather than a cloned connection. In bandwidth leveling, data bursts pending on initiating hosts that exceed a predetermined size are scheduled for transmission to receiving hosts.

A capacitor switch including a power contactor and an impedance contactor located within a relatively slender container filled with dielectric gas. The container may be a “dead tank” or an insulator. For the insulator configuration, the switch also includes a conductive cap housing a charging impedance located on the end of the insulator. The power contactor includes a relatively fixed probe contact and a linearly moving socket. The impedance contactor is ring-type butt contactor surrounding the penetrating contactor that includes a retracting (but otherwise fixed) contact that surrounds the fixed probe, and a traveling ring contact that surrounds and moves with the moving socket contact. The impedance contactor closes before the power contactor on the closing stroke to introduce the charging impedance into the circuit. A puffer mechanism retards the expansion of the retracting contact on the opening stroke, which causes the impedance contactor to open before the power contactor.
