The data storage structure is organised as a plurality of sets, where each set comprises a cache block from each way, and further the data storage structure comprises a first data array and a second data array, where at least the second data array is set associative.

Access circuitry is then responsive to an access request to perform a lookup operation within an identified set of the set associative tag storage structure overlapped with an access operation to access within the first data array the subset of the cache blocks for the identified set. In the event of a hit condition being detected that identifies a cache block present in the first data array, that access request is then processed using the cache block accessed within the first data array. If instead a hit condition is detected that identifies a cache block absent in the first data array, then a further access operation is performed to access the identified cache block within a selected way of the second data array. Such a cache structure provides a high performance and energy efficient mechanism for storing cached data. |

Macular degeneration stick-on-eyeglass filters to reduce glare and distortion
People with (AMD) Adult Macular Degeneration have great difficulty seeing, because their damaged retina sees double vision and distortion. The vision loss is a deterioration of light sensing cells of the retina. Direct or reflecting sunlight and headlights cause extreme glaring and distortion. There are magnifying binocular-fitted eyeglasses for precise detail, and an eye patch, which entirely blocks out all vision, which puts strain and pressure on the dominant eye. Not much is offered to block bright glare, distorted images and double vision associated with AMD.This invention enables adults and children with AMD to self-apply a stick-on eyeglass multi-colored filter UV protectant disc, placed only in front of the affected eye's pupil, on the front of the eyeglass lens. An eye patch blocks all vision completely. However, this invention is an improvement, by which the user chooses optional translucent or solid multi colored, self-applied color filter discs, having different elective properties, which blocks only the affected retina from bright sun, reflections, headlight glare, double vision and distortion, without affecting the users peripheral (side view) vision. |

The proposed method relates to hydrocarbon production, particularly to the monitoring of well operations by way of data analysis based on the cepstral analysis of the well pressure data recorded at the wellhead. The method assumes the detection of a hydraulic signal-reflecting object in the well, wherein: a fluid-filled well is provided with fluid enabling propagation of a hydraulic signal; a hydraulic signal source is provided, said source being in fluid communication with the well and designed to generate a hydraulic signal; a pressure sensor is provided, said pressure sensor records the hydraulic signal and being in fluid communication with the well and at least one hydraulic signal source. The hydraulic signal is recorded with the pressure sensor during well operations, and a pressure cepstrogram is obtained and an intense signal is found on the pressure cepstrogram. Then the position of object reflecting the hydraulic signal is detected in the well. A system is proposed for constructing a pressure cepstrogram and detecting a downhole object. |

Advanced drill string inground isolator housing in an MWD system and associated method
A housing defines a through passage along its length and is configured to support a group of electrical isolators surrounding the through passage to form an electrically isolating break in a drill string such that each isolator of the group of isolators is subject to no more than a compressive force responsive to extension and retraction of the drill string. The housing defines a housing cavity to receive an electronics package having a signal port and is configured for electrical connection of the signal port across the electrically isolating break. A housing lid can cooperate with a main housing body to define elongated slots for purposes of enhancing the emanation of a locating signal. A housing arrangement can support electrical connections from an electronics package to bridge an electrically isolating gap. |

Compression-set straddle packer with fluid pressure-boosted packer set
A compression-set straddle packer with fluid pressure-boosted packer set has a two-part multicomponent mandrel and a multicomponent sliding sleeve that reciprocates within a limited range on an upper part of the two-part multicomponent mandrel. A two-part lower packer element compression sleeve in a lower part of the two-part multicomponent mandrel reciprocates on a packer element piston mandrel component and pressure-boosts compression of a lower packer element when high-pressure fluid is pumped into the straddle packer. A bias element constantly resists relative movement between the multicomponent mandrel and the multicomponent sliding sleeve and balances pressure-boost between the lower packer element and an upper packer element supported by the upper part of the two-part multicomponent mandrel. |
