The present application relates to a system and method for real-time monitoring and failure prediction of electrical submersible pumps. The design includes generating a failure prediction value with a management system by calculating a percentage change of the respective first measurement values and the corresponding user-supplied stable operating values, the failure prediction value representing likelihood of failure of the electrical submersible pump.

A shutter unit for a vehicle, capable of properly determining failure of a shutter without using a sensor which directly detects a position of the shutter. The shutter unit includes a return spring for returning the shutter to a predetermined initial position by urging the shutter, and a rotating machine configured to be capable of converting input motive power to electrical power and input electrical power to motive power by electromagnetic induction action. The rotating machine drives the shutter by the motive power obtained by conversion. The shutter unit executes return control that stops supply of electric power to the rotating machine to return the shutter to the initial position by urging of the shutter by the return spring, and determines failure of the shutter based on a rotating machine induced voltage of the rotating machine, detected during execution of the return control.

A method for correcting double failures in a storage array has the following steps. A storage array is organized as a plurality of concatenated sub-arrays, each sub-array including a set of data storage devices and a row parity storage device. Row parity is computed for each row of each sub-array. The row parity of a particular sub-array is stored on a row parity storage device of the particular sub-array. A diagonal parity is computed across the concatenated sub-arrays. A double storage device failure is corrected using both the sub-array row parity and the diagonal parity.

An image forming apparatus includes a fixing member for fixing toner images on a sheet by heat, a first blowing device for blowing air for cooling the fixing member, and a second blowing device for blowing air for cooling the sheet on which toner images are fixed by the fixing member at the downstream side in conveying direction from the fixing member. The second blowing device blows air at a flow rate related to a flow rate at which the first blowing device blows air.

Systems, methods, and computer program products for enhancing tolerance of data loss in a disk array system have been provided. Systems include a redundant array of independent disks (RAID) storage system including an array of hard disk devices (HDDs) organized in a two dimensional structure of rows and columns of HDDs. The system includes a full stride logically partitioning the rows and columns of HDDs into rows and columns of elements, the full stride including an element from each HDD in the rows and columns of HDDs, each element in the full stride residing on a physically independent HDD. Each element has an element type, wherein a first element type is a data element and a second element type is a checksum element. The system further includes a row checksum element calculated as a checksum of all data elements in a row of the full stride, and a column checksum element calculated as a checksum of all data elements in a column of the full stride, wherein the row checksum element calculation and the column checksum element calculation intersect at a single data element. The system also includes a device adapter for controlling access to the array of HDDs, the device adapter calculating the row checksum element and the column checksum element, the row checksum element and the column checksum element utilized to correct one or more failures in the array of HDDs.

The present teachings relate to a printhead maintenance station for an industrial printing apparatus which is used to prevent clogging of the printhead, particularly during periods in which the printheads are idle. The maintenance station includes a capping station which has sockets for keeping the printheads moist and a blotting station for cleaning any residual printing fluids prior to carrying out a print function.

The present invention discloses a method for screening a sensing margin generated by a gate residue in a memory cell transistor. The method for screening failure of the memory cell transistor is summarized as follows. A test mode signal for sensing margin control is supplied. A write operation is performed to store data in the cell transistor. A word line is enabled by an active command. Isolated transistors disposed between a bit line coupled to the cell transistor and a bit line coupled to a sense amplifier are disabled to intercept a sensing operation. A voltage of the bit line coupled to the cell transistor is measured for a predetermined time. Here, voltage variations on the bit line are measured to screen failure of the cell transistor.
