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： Embedded surface wave antenna elements incorporating different dielectric materials or other features are provided. The different dielectric materials can arranged adjacent a feed, to absorb energy that can cause undesirable reflections in the antenna element. In addition or alternatively, different dielectric materials can be arranged to alter the velocity of energy through the antenna element, and to control or attenuate the formation of nulls in the far field at angles of interest. The control or attenuation of nulls in the far field at angles of interest can further be controlled through contouring an antenna element ground plane in a lens region of the antenna element. A buried feed arrangement is also described.

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： A magnetic recording process generally including the steps of determining an initial magnetization direction of a magnetic recording medium, and selectively applying a magnetic field to the magnetic recording medium along an axis substantially perpendicular to an axis of the initial magnetization direction of the recording medium. The magnetic field is selectively applied for a period of time sufficient to switch the magnetization of the magnetic recording medium from its initial magnetization direction to a final magnetization direction substantially anti-parallel to the initial magnetization direction. Typically, the initial and final magnetization directions will be along an easy axis of magnetization of the magnetic recording medium.

摘要： A magnetization sensor for sensing write field characteristic of a perpendicular or longitudinal recording head such as may be used with a disc drive, and a method of manufacture therefor are disclosed. The sensor can be manufactured concurrently with the write head and incorporated therein. The magnetization sensor comprises a non-magnetic layer separating a hard magnetic layer and a soft magnetic layer, with electrical leads to provide a biasing and sensing current. The magnetization sensor can be either a giant magnetoresistive element or a tunneling magnetoresistive element, depending upon the non-magnetic layer used in the construction of the device.

摘要： The invention is a miniature electro-optic voltage sensor system capable of accurate operation at high voltages without use of the dedicated voltage dividing hardware typically found in the prior art. 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： This invention relates to method and apparatus for measuring noise margins in digital transmission systems. The method requires the introduction of a variable pulse into a sequence of pulses which represents normal traffic, varying a parameter of the pulse, detecting the pulse, and accumulating information concerning the variations to determine probability distribution of the deviations produced by measuring the variations relative to a standard. The apparatus includes means for introducing the variable pulse into a sequence of pulses and for observing and recording detection of the variable pulse in each sequence to compile a probability distribution of the aforementioned deviations.
