One or more multi-layer systems are used to perform inference. A multi-layer system may correspond to a node that receives a set of sensory input data for hierarchical processing, and may be grouped to perform processing for sensory input data.

Systems and methods for improving accuracy in recognizing and neutralizing injection attacks in computer services
Systems and methods for analyzing SQL queries for constraint violations for injection attacks. Tokenizing a SQL query generates a token stream. A parse tree is constructed by iterating over lexical nodes of the token stream. The parse tree is compared to a SQL schema and access configuration for a database in order to analyze the SQL query for constraint violations. Evaluation flaws are also detected. A step-wise, bottom-up approach is employed to walk through the parse tree to detect types and to ascertain from those types whether the condition for SQL execution is static or dynamic. SQL request security engine logic refers to predetermined protective action data and takes the particular type of action specified by the predetermined protective action data. Security is further enhanced by limiting service of requests to requests of one or more specific, accepted data types. Each request is parsed into individual data elements, each an associated key-value pair. If the key is any data element of the request matches a predetermined allowed key, detection and neutralization of any injection attack in the associated value data of the data element is bypassed. A number of patterns that match information to be obscured in logs are established and any matching information is replaced with obscured data. When recording information to the logs, any data whose key is a predetermined masked key is replaced with obscured data. |

A system and method for efficiently forwarding cache misses to another level of the cache hierarchy. Logic in a cache controller receives a first non-cacheable load miss request and stores it in a miss queue. When the logic determines the target address of the first load miss request is within a target address range of an older pending second load miss request stored in the miss queue with an open merge window, the logic merges the two requests into a single merged miss request. Additional requests may be similarly merged. The logic issues the merged miss requests based on determining the merge window has closed. The logic further prevents any other load miss requests, which were not previously merged in the merged miss request before it was issued, from obtaining a copy of data from the returned fill data. Such prevention in a non-coherent memory computing system supports memory ordering. |

Coal mine advanced detection method for heading machine
When the heading machine tunnels, a current generated by a current excitation source enters a coal seam through a movable cutting pick to form a stray current. The stray current collected by a backflow net returns to a negative electrode of a power supply through a transition resistor. When information such as the water content of the coal seam changes, the stray current and a potential difference across the transition resistor also accordingly change, and the coal seam water content information is converted into an electric signal. When the potential difference across the transition resistor is applied to two ends of a piezoelectric ceramic, the piezoelectric ceramic extends or compresses, and the electric signal is converted into a strain signal. A sensing optical fiber converts the strain signal into an optical signal detectable by a photoelectric detector. The optical signal is analyzed to obtain the coal seam water content information. |

Detection systems for power tools with active injury mitigation technology
Power tools with conductive couplings used with active injury mitigation technology are disclosed. Conductive couplings are particularly relevant to table saws, hand-held circular saws, track saws, miter saws, and band saws with active injury mitigation technology. Conductive couplings provide a mechanism through which an electrical signal can be coupled or imparted to a blade, and then monitored for changes indicative of human contact with the blade. An exemplary conductive coupling includes a brush that establishes an electrical connection with a moving part of a power tool, and the brush maintains contact with the moving part of the power tool during at least 40 hours of cumulative time when the motor is spinning the arbor and blade without an interruption in the electrical connection sufficient to trigger the reaction system. A conductive coupling may be two-sided compliant. A conductive coupling may connect to a motor shaft to minimize electrical noise. |
