Multi-format pipelined hardware decompressor
Data compression schemes may indicate the length of the compressed data block in a header or in the compressed data itself. If the start and end of the data block are known before the decoding process has completed by the decoding stage, a header processing stage can ‘skip ahead’ to the start of the next block to begin processing the header of the next block while the current block is still being decoded. Thus, the header processing stage and the decoding stage are operated concurrently. If the end of the compressed block is indicated in the compressed data itself the end of the data block is not known until the end of the compressed data block is reached. For these types of compressed data blocks, the header processing stage waits until the decoding stage finishes with the preceding block before processing the header of the current block. |

Methods and systems for efficient identification of glitch failures in integrated circuits
Methods and systems are described to efficiently identify the potential for failures in integrated circuits (ICs) caused by glitches. In an IC based on synchronous operation, the operation of the multiplicity of inputs, storage elements and observed outputs in said IC are synchronized to one or more clocks that determine the specific times at which inputs change, outputs are observed, and stored values are updated. Almost all ICs are based on synchronous operation. When input values to a logic circuit in an IC change, the effects of said changes propagate through paths in said logic circuit in a delayed manner such that each of said paths may have a different delay. Said different delays can cause a wire in a logic circuit to have transient values (termed “glitch”) before settling to a final value consistent with the input values being applied to said logic circuit. An IC is likely to function erroneously, referred to as having a “glitch failure”, when a glitch value is observed at an output or captured by a storage element. Glitch failures are difficult and expensive to diagnose in a manufactured IC. To raise the productivity of IC development, it is imperative that any potential glitch failure in an IC be detected prior to manufacture. Said detection is hard because a typical IC has a very large number of logic circuits to analyze for glitch failure. To be practical, said analysis must have high performance and high accuracy. Said high performance requiring that said analysis should complete in acceptable run time even for the largest ICs. Said high accuracy requires that said analysis should identify all potential for glitch failure (100% recall), and minimize the number of logic circuits erroneously reported as having glitch failure potential (high precision). Whereas the glitch phenomenon, the potential for glitch failure and methods for detecting glitch failures in pre-manufacture IC models are well known, achievement of high performance with high accuracy has not yet been addressed in prior art. Whereas conventional methods for glitch checking are inefficient and insufficiently accurate, the methods and systems described in the present invention achieve new levels of performance, scalability and accuracy in said detection of glitch failures in an IC. Said methods and systems are based on a novel dissection of glitch-checking requirements into a multiplicity of individual steps, which said steps executed in a systematic sequence deliver high performance and accuracy. |

Bladeless wind turbine
A bladeless wind turbine that creates electrical energy using hydraulically connected pistons. The system may include a disk, a small piston in fluid communication with a large piston, and a crankshaft attached to the large piston. The disk transfers forces from the wind to the small piston.

Consequently, the disk and associated small piston are pushed back to the beginning of the stroke by the pressure created by the large piston's weight. This process is repeated by closing the gate in the disk. A crankshaft powering an electric generator is turned by the movement of the large piston. |
