摘要： A frequency-control circuit, which is configured to receive a first signal having a first untuned frequency from a first oscillator, and to alter one or more pulses of the first signal to tune an output frequency of an output clock signal to have an average frequency at the desired target frequency. In some embodiments, the frequency-control circuit receives a signal from a single oscillator to generate a calibrated, precise, and temperature-stable clock.

摘要： A frequency-control circuit, which is configured to receive a first signal having a first untuned frequency from a first oscillator, and to alter one or more pulses of the first signal to tune an output frequency of an output clock signal to have an average frequency at the desired target frequency. In some embodiments, the two oscillators of intentionally different frequencies are periodically switched at a duty factor, which is dependent on an absolute temperature, to generate a calibrated, precise, and temperature-stable clock.

摘要： A transducer is optimally driven at or near its resonant frequency by a driver system that adapts to variations and/or changes to the resonant frequency of the transducer due to variations in piezo materials, manufacturing, assembly, component tolerances, and/or operational conditions. The system may include an output controller, a phase track controller, a frequency generator, a drive, circuitry to determine a phase angle between the transducer voltage and transducer current, and circuitry to obtain transducer admittance from the transducer voltage and transducer current.

摘要： The method of the present invention for bagging pre-silage, has the steps of (a) receiving a bale of pre-silage from a loader, (b) compressing the bale in at least one cross section dimension to fit into a bag, and (c) advancing the compressed bale into the bag. The apparatus of the present invention for bagging baled pre-silage, has (a) a support frame having a plurality of lateral walls. The lateral walls define a rear opening to which a bag is attached, and a front opening through which is received the baled pre-silage. At least one of the lateral walls is reversibly movable in a direction toward an opposite lateral wall for compressing or squeezing the baled pre-silage to a size that will fit into the bag. The front opening has a closure and ram for enclosing the baled pre-silage and applying the ram to advnce the compressed baled pre-silage through the rear opening and into the bag. Within the bag, the baled pre-silage is free to expand and completely or nearly completely fill the cross section of the bag.
