Abstract: A storage controller and an operating method of the storage controller are provided. The storage controller includes processing circuitry configured to read sub-stripe data from each of a plurality of non-volatile memory devices connected with a RAID (Redundant Array of Inexpensive Disk), check error information of at least one of the sub-stripe data, and perform a RAID recovery operation in response to the at least one of the sub-stripe data having an uncorrectable error, and a RAID memory which stores calculation results of the RAID recovery operation.

Abstract: A missile detent and release apparatus which is capable of detaining and rapidly releasing a missile in a launch tube when conveying/launching the same, and in particular to an improved missile detent and release apparatus by which the missile is easily detained and rapidly released with only a small amount of force, and by which the missile can be stably detained in the launch tube conveying the missile, which includes a pair of detaining protrusions protruded from one end portion of a missile, a pair of fixing members fixed on an inner surface of a missile launch tube and having a detaining groove into which the detaining protrusion is inserted, with the fixing members being formed in the forwarding direction of the missile, a detaining screw passing through a detaining groove of each fixing member in the forwarding direction of the missile and engaged to a detaining screw hole formed at the center portion of the detaining protrusion for detaining the missile in the forwarding direction of the missile, a re

Abstract: An improved missile restraining apparatus capable of effectively protecting a missile from an external impact and quickly releasing a missile restraining state when launching missile, which includes a pair of protrusions having a circular cross-section and formed in the rear portion of a missile, and a pair of brackets fixed to the inner surface of a launch tube and formed so that a pair of restraining grooves corresponding to said protrusions are formed in a predetermined direction, wherein one end of said restraining groove has a circular cross-section, and the other end thereof is shaped to have an elongating axis longer than the diameter of the protrusion in the radial direction and to have the same shorter axis as the restraining groove in the vertical direction.
