A jewelry piece to hold the ends of a plurality of parallel beaded jewelry strings has two interdigitated U shaped bodies. The STO oscillation layer has a large angle magnetization oscillation frequency that is locked to a magnetic medium bit resonance frequency f0 when the rf current has a frequency f=f0 and a threshold current density is applied. The filters hold the number of bits representing a pixel constant throughout the entire operation, conserving processor capacity and throughput when performing video analytics. In this type setup, not only can the position of the pilot valve be a control variable, but the velocity of actuation of this valve can also be used as another control variable.
