Abstract: A single-sided or reversible belt includes a single-sided or double-sided belt strap without any adjusting hole, any popular belt buckle of a frame style or plate style with its prong or projection removed, and new belt fastening means. The belt buckle is providable with a retainer loop on the rear side adjacent an outer end to keep the outer end portion of the belt buckle from dangling after belt buckling. A first fastening element is installed on underside or double sides of a belt strap free end portion, for example. An adjustably slidable locking belt clip is then used to engage a belt strap fixed end portion and carries a mating second fastening element. For belt fastening, the belt clip is manually slid along the engaged belt strap end portion to keep the two fastening elements aligned, leading to having them fastened together. This kind of belt may be used on such articles as trousers and shoes.

Abstract: An apparatus, system, and method are disclosed for assuring uninterruptible battery power for a typical electric motor vehicle powered by an array of series-connected member batteries. Such assurance results from a provision of an electrically-operated bypass switch configured to form a closed electrical bypass circuit path across a faulty first member battery upon activation, thus keeping the vehicle powered up. In one embodiment, the bypass switch is a double-pole multi-contact selector switch connected to each member battery and complimented by a pole-connect switch. For an atypical electric motor vehicle, such as with a multiple battery array parallel configuration, a backup battery may be provided and connected with the faulty battery array in series to displace the bypassed member battery, thus maintaining equal voltage outputs from the battery arrays.

Abstract: An apparatus, system, and method are disclosed for automatically displacing a faulty in-use member battery in an electric equipment, such as electric vehicle, powered by an array of member batteries configured to self detect battery fault conditions and output a control signal upon such detection. By use of a charged spare battery and deactivated single pole double throw relay switches with activation means for coupling all batteries, member batteries are normally interconnected in series electrically to provide a predetermined voltage, with the spare battery standing by. While the electric equipment is in operation, as soon as a member battery detects a fault, the corresponding relay switch is activated to cause the faulty member battery to be electrically bypassed by the battery array. Concurrently, the spare relay switch is activated to electrically connect the spare battery to the battery array in series, thereby displacing the faulty in-use member battery.

Abstract: An apparatus, system, and method are disclosed for a storage device's enforcing write recovery of erroneous data. The storage device enforces write recovery leading to a reassignment and re-write for the defective data block by the storage controller at a subsequent write opportunity with a usual write without verify command. The invention enables the storage device to identify, and re-discover the defect by automatically verifying the data written, and report an unrecovered write error to the storage controller on said write command, causing said write recovery to occur.

Abstract: Disclosed is a system and a method for reliable failover involving incomplete redundant arrays of inexpensive disks (RAID) writes in clustering systems. The system comprises the restructuring of a mirror race table (MRT) and a storage location that may be a non-volatile random access memory (NVRAM) module in a shared disk enclosure to make the MRT accessible to all nodes in the system. In one embodiment, the NVRAM module comprises copies of MRTs from each node operating within the cluster system.

Abstract: A mounting frame located in a computer cabinet equipment drawer can be transitioned to a loading position to receive an electrical device. The mounting frame in the loading position provides ample manipulation space for connecting or removing the electrical device. The mounting frame may also be retracted to an operational position. The retracted mounting frame allows the electrical device to be positioned in a dense array with minimal space between electrical devices. The mounting frame supports positioning a plurality of electrical devices in dense arrays within a computer equipment cabinet equipment drawer while also providing an adequate manipulation space for connecting and removing the electrical devices. The arrangement allows the electrical devices to be hot swappable while still being densely located.

Abstract: A method for determining a change in the SAF-TE enclosure status and a change in the SAF-TE device slot status, each with a single issuance of one new command, replacing countless re-issuance of similar commands. Use is made of a common disconnection/reconnection capability as well as a tagged command queuing technique, such that multiple types of status changes in a SAF-TE enclosure are concurrently determined. Since each of the new commands described here is initiated by the host adapter, the host adapter is prepared for receiving asynchronously a changed status from the reconnecting target device such as a SEP whenever it becomes available, without resorting to use of a complex SCSI protocol known as “asynchronous event notification.

Abstract: A disk array storage system and error recovery method wherein recovery from disk errors is achieved using automated selective power cycling. Initially, identification is made of a faulty disk drive in the array that exhibits an error condition in which the drive fails to perform a requested operation. The faulty disk drive is selectively power cycled while power to other disk drives in the array is maintained. Following the power cycling sequence, the requested operation is retried.

Abstract: A table for identifying potentially bad location addresses based on prior knowledge and performing specific operations using the table data to ensure write recovery is disclosed. A Write Recovery Table (WRT) is provided, which consists of a list of LBAs requiring such special write recovery action so that a WRITE AND VERIFY command is issued instead of a WRITE command. If the WRITE AND VERIFY command fails, the RAID controller can issue a REASSIGN BLOCKS command for the bad block and re-issue the WRITE AND VERIFY command. If WRITE AND VERIFY commands are not supported, then the system can use a READ command with the “Force Unit Access” flag bit being set to “1” to verify the written data. Further, the WRT may be combined with Bad Data Table (BDT) to reject a Read Request from the host for a matched LBA (that is listed therein) because the data in the addressed block is known incorrect when a write recovery action is not warranted.

Abstract: The invention provides system, apparatus, method, and computer program for dynamically expanding a storage system, particularly a RAID (Redundant Array of Independent Disks) set based storage system, while assuring data integrity during the expansion process. In one embodiment, the invention provides a method for redistributing data in a data storage system. This embodiment of the method includes the steps of: identify data in a destructive zone of the storage system; migrating data before reaching the destructive zone from source storage devices to destination storage devices; copying data onto a number of backup buffers; mirroring data backed up in the copying step onto free space in the storage system; migrating data backed up in the mirroring step to destination storage devices; repeating the steps of migrating, copying, and mirroring, until data that will be in the destructive zone is migrated out of the destructive zone; and migrating remaining data from the source disks onto the destination disk.
