    • A switched-geometry arrangement and method for processing outputs from microphones (40.1-40.M) by: receiving signals from the microphones at respective inputs; switching (41.1-41.M) the signals received at the inputs between outputs; summing (42.2.1-42.M.N) desired ones of the outputs and performing array processing (43) to produce a switched-geometry output signal. Operating the switches alters the configuration of microphones connected to the array processor (43), and the switching and subsequent processing may be adaptively operated in dependence on the output signal. Performing the switching in analogue circuitry and subsequent processing digitally allows lower cost, size and power consumption than fully digital processing. Most advantage is expected when a large number of microphones (say 50 or more) is connected to a much smaller number of array signal processor inputs, and especially when the analogue switches and adders are integrated into a silicon chip along with a microphone (e.g. MEMS device) array.
    • 一种用于通过以下步骤处理来自麦克风(40.1-40.M)的输出的开关几何结构和方法:在相应的输入处从麦克风接收信号; 切换(41.1-41.M)在输出端之间输入的信号; 求和(42.2.1-42.M.N)期望的输出和执行阵列处理(43)以产生切换几何输出信号。 操作开关改变连接到阵列处理器(43)的麦克风的配置,并且切换和后续处理可以根据输出信号自适应地操作。 在数字处理中进行模拟电路和后续处理的切换允许比完全数字处理更低的成本,尺寸和功耗。 当大量麦克风(例如50个或更多)连接到更少数量的阵列信号处理器输入端时,尤其是当模拟开关和加法器与麦克风一起集成到硅芯片中(例如MEMS 设备)数组。

    • A camera (30) uses an electro-active device (11) to position a movable lens. The electro-active device (11) comprises an electro-active structure in the form of a continuous electro-active member (12) curving in a helix around a minor axis (13) which is in itself curved for example in a helix around a major axis (14). The continuous member (12) has a bender construction of a plurality of layers (21 and 22) including at least one layer of electro-active material so that it bends, on activation, around the minor axis (13). Concomitantly with the bending, the electro-active structure twists around the minor axis. Concomitantly with that twisting, relative displacement of the ends (16) of the device (11) occurs due to the combination of the twisting around the minor axis (13) and the fact that the minor axis (13) is curved. This structure of the electro-active device (11) is compact and provides for linear displacement, thereby making it suitable for positioning the lens of the camera (30).

    • A modular raised bed garden system includes a number of raised-bed modules that may be assembled according to one or numerous different configurations. The raised bed modules include a first arcuate-shaped bed module having a first radius of curvature and a second arcuate-shaped bed module having a second radius of curvature that is smaller than the first radius of curvature. The first bed module may be coupled to the second bed module, forming a raised bed garden system. The modules may be connected end-to-end through a connection module, such as one or more bolts secured through end-plates of each module. A third arcuate-shaped bed module having a smaller third radius of curvature may be coupled to the system and arranged to produce a spiral or S shaped system. Display and trellis modules may be coupled with the raised beds to provide shading and aesthetic features.
