A nonvolatile memory system includes a memory control module that encodes data to provide encoded logical data structures. The composition of the invention is based on an association of omega 6 polyunsaturated acids and rutin in a pharmaceutically acceptable carrier. As a result, the fixing base for fixing the accessory handle can be combined at the locking section of the handle and standpipe when the middle section of the handle is locked in an arc groove positioned at the front end of the handle standpipe and the combination groove is combined with a standpipe. The audible alarm device is capable of issuing a distress sound audible to human ear. The user generated data is analyzed with the reference point using more than two frequencies, at the controller, to obtain a variation in measurement of the head-disk clearance. The sensors communicate with a signal-processing unit which transmits amplified sensor signals to a monitor which is accessible to personnel aboard the ship.
