    摘要： An aid to tuning musical instruments. A microprocessor-controlled frequency standard is used to control a shift-register whose data is the digitized sound detected by a microphone. The data from the shift register are loaded into a parallel-load latch and then used to control an array of indicator lights. The pattern in the lights indicates the error in pitch of the sounded note. A person tunes a musical instrument by making the pattern in the lights become nearly stationary. The same synthesized frequency is made available in a speaker.

    摘要： A processor includes a cache, a prefetcher module to select information according to a prefetcher algorithm, and a prefetcher algorithm selection module. The prefetcher algorithm selection module includes logic to select a candidate prefetcher algorithm determine and store memory addresses of predicted memory accesses of the candidate prefetcher algorithm when performed by the prefetcher module, determine cache lines accessed during memory operations, and evaluate whether the determined cache lines match the stored memory addresses. The prefetcher algorithm selection module further includes logic to adjust an accuracy ratio of the candidate prefetcher algorithm, compare the accuracy ratio with a threshold accuracy ratio, and determine whether to apply the first candidate prefetcher algorithm to the prefetcher module.

    摘要： A fluorometric titrator has means to transfer a pipette between first and second positions and a buret for a chelating agent has a reversible drive powered either by a pulse generator or an oscillator. Valve controlled means are operable to place the buret in communication with the pipette or a reservoir. In the first position of the pipette, a precise sample volume is aspirated into it by the buret, then driven by the oscillator and in its second position and with the buret drive reversed but still powered by the oscillator, the sample volume is discharged from the pipette into a cuvette in the fluorometer. On the resulting fluorescence the fluorometer output drives the pulse generator to dispense chelating agent and to operate a counter until a selected end point is reached. The pipette is then returned to its second position with the buret drive again operated by the oscillator and during the return, the buret is refilled. Both before the sample volume is aspirated, and before that volume is discharged, backlash is removed from the buret drive. The effect of hysteresis on the photocell of the fluorometer is minimized by light control also enabling the response time of the titrator to be accelerated.
