摘要： A panel of microwave absorbent material comprises at least one layer of a ferrite substrate, a backing reflector capable of reflecting incident radiation, and means for applying a magnetic field to the substrate. The applied field changes the ferromagnetic resonance behaviour of the ferrite and hence the absorption characteristics of the substrate can be changed. It is possible to produce materials switchable or biasable to negate the absorbent effect of the ferrite layer, enabling the device to switch from an essentially absorbent to an essentially reflective state.
摘要翻译：一组微波吸收材料包括至少一层铁氧体衬底，能够反射入射辐射的背衬反射器，以及用于向衬底施加磁场的装置。施加的磁场改变了铁素体的铁磁共振特性，因此可以改变衬底的吸收特性。可以生产可切换或可偏压的材料以消除铁氧体层的吸收效果，使得该装置能够从基本上吸收性转变为基本反射状态。

摘要： A means for increasing the drag of a munition to effect a course correction having coplanar interlocking pairs of drag plates (24, 26) being laterally extendable from an undeployed configuration, substantially contained within the munition, to a deployed configuration. The drag plates (101, 103) are provided with projections (34, 38) and slots (36, 40), the projections (34, 38) of one of a pair of drag plates being adapted to locate in the slots (34, 40) of the other drag plate in the undeployed configuration and being adapted such that they extend beyond halfway into the munition. A deployment means (60, 62, 70, 72) retains the drag plates in the undeployed configuration until receipt of a control signal and then effects deployment of the drag plates, the distance travelled between the deployed and undeployed configurations being determined by the extent of the projections (34, 38).

摘要： A damage sensor for detecting damage within a structure such as aircraft wings or fuselage, or a bridge. The sensor comprises a small piece of a triboluminescent material connected via light guiding fibres or layers to one or more detectors. The sensor may be embedded within the structure or mounted on its surface. Impact of objects on the structure causes a physical damage to the triboluminescent material. Such damage causes light emission which is detected and recorded for later observation. The intensity of emission may be measured to give an indication of amount of damage received by the structure. Several different triboluminescent materials may be arranged in different locations within the structure so that location of damage may be detected by a single detector sensitive to the different wavelengths of light emitted by the several materials. Light from the triboluminescent material may be detected directly by the detectors. Alternatively, material doped with suitable photo excitable dyes may be caused to photo excite, and the resultant light output detected.

摘要： An infrared optical system (100) incorporates a lens (118) imaging a remote scene onto a detector (112) within a cold shield (114). Stray radiation incident on the detector (112) is reduced by an optical stop in the form of a light emitting diode (LED) (126) producing negative luminescence. The LED (126) emits less radiation than background, and contributes less to the detector photon noise than an optical stop not exhibiting negative luminescence.

摘要： Biomaterial, for example bioactive silicon, may be fabricated by anodising a silicon wafer to produce a wafer (10) having a porous silicon region (20). In vitro experiments have shown that certain types of porous silicon cause the deposition of apatite deposits both on the porous silicon (20) and neighbouring areas of bulk silicon (22) when immersed in a simulated body fluid solution. This deposition of apatite provides an indication that porous silicon of appropriate form is bioactive, and therefore also biocompatible. A form of porous silicon is dissolved in the simulated body fluid solution and this is an indication of a resorbable biomaterial characteristic. In addition to porous silicon, certain types of polycrystalline silicon exhibit bioactive characteristics. Bioactive silicon may be used in the fabrication of biosensors for in vitro or in vivo applications. The bioactivity of the bioactive silicon may be controlled by the application of an electrical potential thereto.

摘要： A method of producing cyclic oligomers of substituted oxiranes and oxetanes involves the slow addition to a solution of the ether in a relatively polar organic solvent such as dichloromethane or dichloroethane, of a stable protonic acid such as HBF4 or a cationogenic species for example triethyloxonium tetrafluoroborate or an alcohol in conjunction with a stable Lewis acid such as boron trifluoride etherate. The cyclic oligomer product is isolated from other reaction products, in particular the straight chain oligomers, by extraction with a non-polar solvent, hexane being preferred. The cyclic products are effective plasticisers for polyether polymers, particularly where the cyclic ether is related to or even the same as the ether in the polymer since compatability of the materials is then very likely and separation out of plasticiser unlikely to occur.

摘要： A covert method of distinguishing between genuine and counterfeit articles by means of applying an optical filter to genuine articles as a mark of authenticity. The filter for use in the method may comprise a multi layer stack having at least one maximum and at least one minimum in the spectral characteristic and a selective absorber over a range of visible wavelengths. The spectral characteristic is such that the filter has a neutral appearance when viewed by an unaided eye under normal lighting conditions, but gives rise to characteristic optical effects when illuminated with selected wavelengths. The characteristic effects provide an authenticating signature for the filter. In the absence of the filter, the illumination would not give rise to the characteristic effects. The intensity of radiation reflected or transmitted by the filter at two or more wavelengths may be used to provide the authenticating characteristic. In an alternative embodiment, the filter may be illuminated with radiation at two or more angles of incidence. The resulting intensity or spatial distribution of radiation reflected or transmitted by the filter may be used to verify the authenticity of the article by comparing the observed properties with known properties for the filter.
摘要翻译：通过将真空物品作为真实标记的光学滤光片应用于真伪伪造品的区分方法。用于该方法的滤波器可以包括在光谱特性中具有至少一个最大值和至少一个最小值的多层堆叠以及在可见波长范围内的选择性吸收器。光谱特性使得当在正常照明条件下由肉眼观察时，过滤器具有中性外观，但是当被选择的波长照亮时，会产生特征性光学效应。特征效果为过滤器提供了认证签名。在没有滤光片的情况下，照明不会产生特征效应。可以使用在两个或更多个波长处由滤光器反射或透射的辐射的强度来提供认证特性。在替代实施例中，可以以两个或更多个入射角的辐射照射滤光器。由过滤器反射或传播的辐射所产生的强度或空间分布可用于通过将观察到的性质与过滤器的已知性质进行比较来验证物品的真实性。
