    • A multi-channel reverberation system has a substantially constant multi-channel power gain at audio frequencies and comprises multiple signal inputs, one for each input channel, a number of comb filter networks connected to each signal input, each comb filter network including a feed forward stage, a cross-coupling network cross-coupling the comb filters to increase the reverberation echo density, and multiple signal outputs, one for each output channel. Preferably the feed forward stage of each comb filter provides a substantially constant multi-channel power gain at audio frequencies and the cross-coupling matrix is an orthogonal cross-coupling matrix cross-coupling a number of single channel allpass comb filters, positioned immediately before or after the delay lines, to create a multi-channel allpass comb filter with a unitary transfer function matrix at all frequencies.

    • A wave energy converter (10) for extracting useful energy from wave motion. The converter (10) comprises an active float (12) that is arranged to float on the water, and being arranged to heave and surge in response to wave motion acting on the active float, and an elongate reactive body (14) that is arranged to be suspended in a substantially submerged state into the water and having sufficient surface area and length such that it pitches in response to wave motion-acting on the reactive body. The active float (12) and reactive body (14) are pivotably coupled for pivotable movement relative to each other about a single pivot axis (16) in response to heaving and surging of the active float and pitching of the reactive body. The converter also comprises a power output system that is driven by the pivotable movement about the pivot axis to capture the useful energy.
    • 一种用于从波动提取有用能量的波能转换器(10)。 转换器(10)包括有源浮子(12),其被布置成浮在水面上,并被布置为响应于作用在主动浮子上的波浪运动而起伏并且被布置成细长的反作用体(14) 以基本浸没的状态悬浮在水中并具有足够的表面积和长度,使得其响应于对反应体的波浪运动而间距。 主动浮子(12)和反作用体(14)可回转地联接,以响应于主动浮子的起伏和反作用体的俯仰而相对于彼此围绕单个枢转轴线(16)枢转运动。 转换器还包括动力输出系统,该系统由围绕枢转轴线的可枢转运动驱动以捕获有用能量。
