A frequency-phase adjusting device includes a first controller, a second controller, and an oscillating circuit. Embodiments of the subcombination and the fruit extraction device of which it is a portion shear the peel in multiple slivers, at the same time compressing the fruit. Systolic registers may be included at various points in the DSP blocks to facilitate use of the blocks to implement systolic form, finite-impulse-response, digital filters. Running in the user space is an event collector, an event player, and a concurrency error detector. A target gear speed shift transmission instruction detector is configured to detect a target gear speed shift transmission instruction.
