Abstract: A panel form loudspeaker comprises a resonant multi-mode radiator (11) which in turn comprises a plurality of substantially concentric sub-panels (20, 21, 22, 23). A plurality of analogue drivers (10) drive the radiator (11), one or more of the drivers being operational at any time. A signal level measured at the input to the loudspeaker determines the operational state of each of the drivers (10). The concentric sub-panels may take various shapes and have different areas.

Abstract: Conventional analogue loudspeakers have a limited dynamic range as compared to the available dynamic range of digital recordings. Digital recordings use up to 24 bits and this implies a dynamic range of 141dB. Digital loudspeakers, involving 2 single bit device (with N = 24, this number is 1.7x10 ) have been proposed. Complexity and poor performance associated with the interaction effects between the different devices have discouraged widespread use of such systems, along with the inability of most loudspeakers to reproduce realistic absolute levels of sound (up to say 120dB at 1m without distortion), so such digital loudspeakers cannot take full advantage of the 24-bit fidelity. This invention provides a loudspeaker with improved dynamic range over prior art systems.
Abstract translation: 传统的模拟扬声器与数字录音的可用动态范围相比具有有限的动态范围。 数字录音最多可使用24位，这意味着141dB的动态范围。 数字扬声器涉及2 N单位设备（N = 24，这个数字是1.7×10 7）。 与不同设备之间的相互作用影响相关的复杂性和差的性能阻止了这种系统的广泛使用，以及大多数扬声器无法再现真实的绝对水平的声音（在1m时达到120dB而没有失真），因此这样的数字扬声器 无法充分利用24位保真度。 本发明提供了一种具有比现有技术系统更好的动态范围的扬声器。

Abstract: An active vibration isolation mount is provided for mounting a first member (1) to a second member (2) and for reducing the transmission of vibrations from the first member (1) to the second member (2). A spring arrangement (3) is arranged between the first and second members. A sensor senses vibrations in the first member. A force actuator (4) applies a controlling force to the second member in response to vibrations sensed by the sensor. The spring arrangement is adapted to provide a delay between the first and second members equal to or greater than a delay in the application of the controlling force by the force actuator (4) in response to the vibrations in the first member. Also a passive mount is provided for mounting a first member (1000) to a second member (1001) and for reducing the transmission of vibrations from the first member to the second member.

The passive vibration isolation mount comprises a first mounting arrangement for mounting to the first member; a second mounting arrangement for mounting to the second member; a spring arrangement arranged between the first and second mounting arrangements; and a mass arrangement coupled to the spring arrangement so as to lie in or adjacent to a region between the spring arrangement and the second mounting arrangement. The spring arrangement is coupled to the first mounting arrangement and provides a spring force between the first and second mounting arrangements.

Abstract: 9059. Nash, M. P. April 9, 1913, [Convention date]. Sights. - Consists in constructing a backsight as a forked slide C embracing the gun and elevated by a spiral groove F in a rotary cam, the groove being open at its outer end F to allow further upward movement of the sight independently of t h e cam. T h e sighting- aperture is formed in a hinged piece D at the top of the slide. The edge of the rotary cam is formed with notches with which a spring J engages, thus forming a clicking indicator.
