Utilities for use in actively detecting the occurrence of bad blocks in NAND flash storage devices and diagnosing the devices as faulty at some point before complete failure of the devices (e.g., before a number of allowable bad blocks has been reached) to allow a corresponding service processor to continue to write to available blocks for a period of time until a replacement NAND flash device can be identified. The utilities may also be utilized to predict the future occurrence of bad blocks in NAND flash devices, such as during the 'burn-in' process of the devices (e.g., which tests the quality of the NAND flash device before being placed into service to weed out devices with defects).

Data is distributed among the channels of an asynchronous data subscriber loop (ADSL) communications system in accordance with an adaptive algorithm which from time to time measures the signal to noise ratio of the various channels and finds a margin for each channel dependent on achievement (where possible) of a given bit error rate and a desired data transmission rate. The margin distribution is achieved by augmenting the constellation signal to noise ratio to enhance computational efficiency and allow redetermination of bit allocation tables during transmission as necessary. Pairs of bit allocation tables are maintained at the transmitter and receiver and one table of each pair at the transmitter and receiver is updated while the other pair is in use for controlling communication.

A system and method for parallel computation of Discrete Sine and Cosine Transforms. The computing system includes a plurality of interconnected processors and corresponding local memories. An input signal x is received, partitioned into P local vectors x, and distributed to the local memories. The preprocessors may calculate a set of coefficients for use in computing the transform. The processors perform a preprocess in parallel on the input signal x to generate an intermediate vector y. The processors then perform a Fast Fourier Transform in parallel on the intermediate vector y, generating a second intermediate vector a. Finally, the processors perform a post-process on the second intermediate vector a, generating a result vector v, the Discrete Transform of signal x. In one embodiment, the method generates the Discrete Sine Transform of the input signal x. In another embodiment, the method generates the Discrete Cosine Transform of the input signal x.

A computer system comprises a plurality of processes, each having an associated memory region, and a shared memory region shared by the processes. One of the processes is configured to control allocation of space for an array in the shared memory region, generate a descriptor therefor pointing to the allocate space and transmit the descriptor to the other processes. Therafter, all of the processes are configured to identify regions of the array for which they are to process data therein, and to perform predetermined processing operations in connection therewith.

A fishing lure is described containing a cast of a natural bait encased in a castable transparent material designed in hydrodynamically correct shapes and to operate at different depths by utilizing an adjustable buoyancy device. A cast of a natural bait being the embodiment of a natural bait in the form of a castable material taken from the cast of a natural bait and then painted, to which an adjustable buoyancy device is incorporated by containment within the lure or attachment to the lure of a sealed air chamber wherein the adjustable portion consists of a cylinder which is threaded on the inside to accommodate a set screw/gasket seal combination. Rotation of the set screw varies the lure's buoyancy by compressing the air in the air chamber thus varying the fluid displacement volume of the lure and also changing the center of gravity of the lure. Alternatively, the cast can be of a part of the natural bait or a section or surface texture of the bait.
