77 results about "Obsolescence" patented technology

Obsolescence is the state of being which occurs when an object, service, or practice is no longer wanted even though it may still be in good working order. The international standard EN62402 Obsolescence Management - Application Guide defines obsolescence as being the "transition from availability of products by the original manufacturer or supplier to unavailability".

Combined pipelined classification and address search method and apparatus for switching environments

A packet switching node having a pipelined packet processing architecture processing packets received via an input port associated with the packet switching node is presented. The method performed by the apparatus includes: determining a packet frame type of the packet received; selectively extracting packet header field values specific to a packet frame type, the extracted packet header field value including packet addressing information; ascribing to the packet a preliminary action to be performed in respect of the packet; searching packet switching information tracked by the packet switching node based on extracted packet addressing information; formulating a preliminary switch response for the packet; classifying the packet into one of a plurality of packet flows; modifying the preliminary switch response in accordance with one of the preliminary action, the packet flow into which the packet was classified, and a default port action corresponding to the input port; modifying the packet header in accordance with one of the preliminary action, the packet flow, and the default port action; and processing the packet in accordance with the switch response. Advantages are derived from: pipelined processing of packets which enables short-cutting the rest of the processing for improper packets; a flexible frame type determination which is fast for well know frame types yet flexible in support of new frame types delaying obsolescence of a particular implementation; an early determination of a processing action which is successively refined by subsequent stages; a combined Layer-2 and Layer-3 network addressing search engine operating on short bit length indexed Layer-2 and Layer-3 network addresses reducing network address table storage requirements, requiring a reduced data transfer bandwidth for network address table access, a large external hashed primary network address table, and a small internal secondary network address table; an early determination of a switch response; and packet-classification-based switch response and packet header modification.

InactiveCN101705741AHigh quality light weight, compressive strengthLight in massCovering/liningsSolid waste managementBrickSilicon oxide
The invention relates to a phase-transition self-temperature-regulating heat-preserving facing brick of an external wall, which is an integrated structure compacted by a phase-transition heat-preserving layer and an inorganic facing layer, wherein the phase-transition heat-preserving layer is mixed by proportion and compacted by hull-type expanded perlite heat-preserving aggregates, phase-transition temperature-regulating aggregates and cements; the inorganic facing layer is mixed by quartz sand, calcium carbonate, calcium oxide, cement and silicon oxide powders; and the phase-transition temperature-regulating aggregate is made of phase-transition cores and encapsulated hulls. The manufacturing method not only effectively solves the encapsulation problem of the phase-transition material, leads the prepared phase-transition self-temperature-regulating heat-preserving facing brick of the external wall to have excellent heat-preserving performance, waterproof performance and permanent anti-ageing performance, but also radically solves the obsolescence of thermo-physical property and the leakage problem of phase-transition material in the circulation process. The facing brick has the advantages of light weight, strong adhesion strength, large compressive strength, heat insulation, heat preservation, waterproof and moisture-proof performances, obvious energy-saving effect, and the like.

Device fault mode identification method based on improved CS-LSSVM

The present invention discloses a device fault mode identification method based on an improved CS-LSSVM. The method comprises the following steps: 1, collecting the monitoring data in the normal condition and the abnormal condition, and performing preprocessing; 2, initializing the Cuckoo search algorithm parameters; 3, building an optimized objective function; 4, updating the bird's nest position through a Levee flight mode; 5, updating the optimized objective function; 6, updating the bird's nest position according to the obsolescence probability; 7, calculating the optimal bird's nest position of the iteration; 8, determining whether the optimal bird's nest position of the iteration reaches the maximum iteration algebra or not, if the iteration does not reach the maximum iteration algebra, returning back to the step 4, and if the iteration reaches the maximum iteration algebra, outputting the optimal bird's nest position; and 9, obtaining the LSSVM optimal penalty factors and the optimal kernel function parameters, and employing the LSSVM to perform fault mode identification of the test sample. The device fault mode identification method based on the improved CS-LSSVM is better in the rate of convergence and the precision of the LSSVM parameter optimization, can obtain globally optimal solution and can be better suitable for the identification of the LSSVM for the device fault mode.

Efficient recycling production process of obsolescence corrugated cardboard (OCC) residue pulp

ActiveCN108914672AFully relievedIncrease productionMachine wet endCardboardFiber
The invention relates to an efficient recycling production process of obsolescence corrugated cardboard (OCC) residue pulp, and belongs to the technical field of pulping and papermaking production. The production process comprises the steps of collecting total gutter tailing, combining coarse screens in a coarse screening section, carrying out concentration, carrying out grinding, carrying out mixing, carrying out dilution, removing sand, carrying out fine screening, carrying out concentration, refining pulp, storing the pulp and conveying the pulp to a paper machine. Through the addition of the combination of the coarse screens with re-crushing and screening functions in the screening section, sundries such as plastic, foam, gravels and the like are effectively prevented from blocking ordamaging disc mills, low-concentration sand removal devices, fine screening devices and the like used in the follow-up treatment process, and meanwhile, a high-power pulping machine is additionally arranged, so that fibers in the tailings are sufficiently defibered, ground and preliminarily separated and fibrillated. The daily tailing treatment amount is 500 t/d, the recovery pulp yield is 400 t/d, and the recovery rate reaches 80% which is greatly improved compared with the recovery rate of 60% in a conventional recovery process. Therefore, OCC residue pulp is efficiently recovered by adopting the production process provided by the technical scheme, and important economic and environmental benefits are achieved.
