Abstract: A method and system for overriding error correction capabilities of digital optical media is provided. The overriding of the error correction codes (ECC) is accomplished by causing a non-correctable pattern of erroneous symbols to occur in the ECC codeword. Specific redundancy symbols are replaced with invalid symbols. The non-correctable error pattern is recognized by the ECC decoder as being non-correctable and the ECC decoder does not attempt to change the values of any symbols of an ECC codeword that is contaminated by the detectable non-correctable error pattern.

Abstract: A rapid installation and removal ladder slide prevention system is an easily installed and removed ladder slide prevention device that may be installed without the use of hand tools. The system may include an upper and a lower U-shaped bracket for each ladder leg that are slid onto the legs and secured by a bolt through the legs of the U-shaped bracket and are each locked into place with a wing nut. A cylindrical sleeve is attached to the back of each U-shaped bracket. A sharpened leg stake is able to be slid through the two sleeves on the two U-shaped brackets on each ladder leg and each adjusted in length in relation the ladder feet, and locked into place by an R-clip passed through holes in the lower bracket sleeves on each lower U-shaped bracket. The device increases ladder safety for users.
