Abstract
As may be implemented in accordance with one or more embodiments, an apparatus and/or method involves a plurality of transducer elements that convert energy waves conveyed via a multi-directional radiation pattern into electrical charge. A power-accumulation circuit accumulates electrical charges from each of the plurality of transducer elements, with each of the transducer elements being arranged at different respective off-axis angles relative to an axis at which the energy is being conveyed. The power-accumulation circuit accumulates energy from each of the individual energy-transduction areas, such that energy received at different respective off-axis angles contributes to the accumulation of electrical charge.
