Abstract:
Provided is a vibratory exercise apparatus having a frame and a handle, including: upper and lower plates formed to be spaced apart from each other at a predetermined interval; a vibrator disposed on a center of the lower plate, having upper and lower vibration plates and installed to be vibrated up and down, and configured to vibrate an operating unit up and down by receiving a drive signal so that the upper plate in contact with the operating unit is vibrated up and down; and a plurality of vibration absorbing units disposed between the upper plate and the lower plate so as to maintain predetermined intervals in an edge region of the lower plate and configured to absorb an impact generated when the upper plate is lowered while the upper plate is vibrated.
Abstract:
Provided is a method of hiding a specified directory with no effect on compatibility with an existing file system. According to an aspect of the invention, an apparatus for managing a hidden area includes a hidden area generation unit which sets a portion of the data area as a hidden area and records meta data for the set hidden area, a hidden area release unit which moves a directory entry of a root directory of the hidden area into the directory entry area and returns a cluster recorded with the meta data to release the set hidden area, and an access control unit which controls an access to the hidden area when the hidden area is set.
Abstract:
Disclosed are an apparatus and a method for storing and managing additional data in a file system. The apparatus comprises a search unit to search for an unused region in a directory entry, a storage unit to store additional data in the unused region, and an additional data managing unit to locate the position of the additional data using the signature and checksum of the additional data. The method includes (a) searching for an unused region of a directory entry, (b) storing additional data in the unused region, and (c) locating the position of the additional data using the signature and checksum of the additional data. According to the present invention, additional data can be stored, used and managed utilizing unused regions of a directory entry without degrading the compatibility of the file system, and enhancing the performance of the FAT file system.
Abstract:
A method and an apparatus are provided for managing blocks according to the update type of data in block-type memory. The method includes receiving data to be stored from an application; determining an update frequency of the data; extracting information of nonvolatile memory space in which the data will be stored according to the update frequency of the data; and transmitting information about the data and the space to the nonvolatile memory so that the data is stored in the space using information of the extracted space.
