    摘要： A handle operating assembly suitable for use with an electric disconnect switch assembly having a circuit breaker. The handle operating assembly comprises a handle operator extending outward from the electric disconnect switch and movable between an ON and an OFF position and a face plate having a slot therein. The handle operator slidably moves in the slot between the OFF position and the ON position. The face plate mounts to the electric disconnect switch assembly and is positionable between a first position to prevent access to the circuit breaker and a second position to provide access to the circuit breaker. The handle operating assembly provides ease of accessibility to the electrical disconnect switch and ease of assembly.

    摘要： Several circuits and methods implemented to perform signal quality estimation and control are disclosed. In an embodiment, a method of signal quality estimation includes generating a demodulated signal associated with a radio signal. Information associated with a quality of the demodulated signal is accessed. Further, a value of radio frequency signal-to-noise ratio (RF-SNR) for the radio signal based on the information is estimated. Estimating the value of RF-SNR facilitates in signal quality estimation of the radio signal and control of the demodulated signal.

    摘要： A method of constructing a hierarchical database from an initial plurality of rules. A first rule of the initial plurality of rules is added to: a first sub-database if a first bit of the rule is a logic ‘0’ value; a second sub-database if the first bit is a logic ‘1’ value; or a third sub-database if the first bit is in a masked state, ‘X’, indicating that the first bit may be either a logic ‘1’ or a logic ‘0’ value.

    摘要： A packet classification device includes a CAM device, an SRAM device, and a control circuit that controls and coordinates the operations of the CAM and SRAM devices. For some embodiments, a first CAM block stores unique entries for each packet header field, a RAM block coupled to the first CAM block stores field labels for the unique packet header fields, a second CAM block stores group labels consisting of unique combinations of concatenated field labels, and a second RAM block coupled to the second CAM block stores a group identification (ID) for each group label, wherein each group ID identifies a corresponding one of the groups of rules.

    摘要： A search tree embodying a plurality of signatures to be compared with an input string of characters and including a number of branches of sequential states originating at a root node, wherein each state comprises a state entry including a failure transition and one or more success transitions, is optimized by selecting a failure size parameter indicating a minimum number of characters to be traversed on the failure transitions and selectively modifying the search tree to create a modified search tree for which all failure transitions to non-root states are characterized by the selected failure size parameter.
