摘要： In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface.

摘要： By sharing tasks between the CV and the KVs, the MKV interceptor provides a cost-effective missile defense system capable of intercepting and killing multiple targets. The placement of the acquisition and discrimination sensor and control sensor on the CV to provide target acquisition and discrimination and mid-course guidance for all the KVs avoids the weight and complexity issues associated with trying to “miniaturize” unitary interceptors. The placement of a short-band imaging sensor on each KV overcomes the latency, resolution and bandwidth problems associated with command guidance systems and allows each KV to precisely select a desirable aimpoint and maintain track on that aimpoint to impact.
摘要翻译：通过在简历和KV之间分享任务，MKV拦截器提供了一种具有成本效益的导弹防御系统，能够拦截和杀死多个目标。采集和识别传感器和控制传感器放置在CV上，为所有KV提供目标采集和辨别以及中间路线指导，避免与尝试“小型化”单一拦截器相关的重量和复杂性问题。在每个KV上放置短带成像传感器克服了与命令指导系统相关的延迟，分辨率和带宽问题，并允许每个KV精确地选择一个理想的目标点，并在该目标点上保持跟踪。

摘要： An expert system having a processor which can receive input data and operate on it to produce data indicative of a parameter or parameters which are considered to define or represent the condition of equipment or a system to be diagnosed and which provides an adaptive pattern recognition facility which can be trained or instructed to recognize different combinations of input data as indicative of particular conditions of the equipment. The system is trained by coupling it initially to known good equipment into which definable faults are introduced. The adaptive pattern recognition facility has a series of sections with adjustable weight coefficients which are adjusted in accordance with a given algorithm as successive data combinations associated with the various faults are fed to the system. Once trained, the system can diagnose unknown equipment and provide outputs indicative of faults.

摘要： A radio frequency reconfigurable lens is provided. In particular, a lens comprising at least two opposed frequency selective surface sheets is provided. A relative phase shift may be imparted to an incident radio frequency wave by varying the distance between at least some of the unit cells of a first of the FSS sheets and adjacent unit cells on a second of the FSS sheets. In order to provide a desired phase taper across the width of a lens, and/or to provide different phase shift amounts, pairs of FSS surfaces having controllable columns or rows can be cascaded together. According to an additional aspect of the present invention, radio frequency waves can be scanned by cascading multiple tunable stages. The present invention also provides a radio frequency shutter.

摘要： A recording head for use with a magnetic storage medium includes a pair of write poles structured and arranged to apply a magnetic write field to the magnetic storage medium and a pair of oppositely directed conductors located adjacent the pair of write poles. The pair of conductors combine to induce the magnetic write field in the pair of write poles. One of the oppositely directed conductors has a positive voltage relative to ground and the other of the conductors has a negative voltage relative to ground, such that the pair of oppositely directed conductors combine to drive the magnetic write field in the same direction. Each of the conductors may be a microstrip waveguide.

摘要： A miniature electro-optic voltage sensor system capable of accurate operation at high voltages without use of the dedicated voltage dividing hardware. The invention achieves voltage measurement without significant error contributions from neighboring conductors or environmental perturbations. The invention employs a transmitter, a sensor, a detector, and a signal processor. The transmitter produces a beam of electromagnetic radiation which is routed into the sensor. Within the sensor the beam undergoes the Pockels electro-optic effect. The electro-optic effect produces a modulation of the beam's polarization, which is in turn converted to a pair of independent conversely-amplitude-modulated signals, from which the voltage of the E-field is determined by the signal processor. The use of converse AM signals enables the signal processor to better distinguish signal from noise.The sensor converts the beam by splitting the beam in accordance with the axes of the beam's polarization state (an ellipse) into at least two AM signals. These AM signals are fed into a signal processor and processed to determine the voltage between a ground conductor and the conductor on which voltage is being measured.

摘要： A method and associated apparatus for measuring the intensity decay time of an optical cavity is particularly useful for accurate measurement of cavities of the type that include highly reflective mirrors. In the method, apparatus is provided for generating at least one pulse of laser light having a bandwidth that exceeds the resonant frequency spacing of the optical cavity and for directing that pulse into the cavity. The intensity of the light within the cavity is then measured and the amount of time is determined for such intensity to decay from a first predetermined value to a second predetermined value.
