摘要： A traveling-wave tube (10) has a confined-flow periodic permanent magnet focusing arrangement (26) in which either the first magnet (60f) or the third magnet (60t) from the electron gun (12) has an extent or axial thickness along the electron stream path which is one-half that of the remaining magnets in the arrangement, thereby providing a scalar magnetic potential of essentially zero on the electron gun pole piece (46), thereby eliminating the field reversal at the cathode (14). This enables a magnetic field to be provided in the region of the electron gun between the gun pole piece (46) and a location behind the cathode due solely to the magnetic field leaking through the gun pole piece aperture (50). The axial magnetic field within the electron gun (12) may be tailored or fine tuned, by varying the size of the aperture (50) in the gun pole piece (46).

摘要： An imaging system incorporating a scanned array of infrared detectors for a presentation of scene data on a display includes gain normalization and averaging circuitry coupled to individual ones of the detectors of the detector array. The gain normalization is accomplished with gain control circuitry structured as a feedback loop introducing equality between the magnitude of an average value of a detector signal and a reference signal. The imaging system comprises a set of channels connecting with respective ones of the detectors, each channel having a gain control circuitry. A common value of the reference signal is applied to each channel. The averaging time is several times greater than the duration of a single scan in the scanning of the detector array so as to introduce gain normalization to subject matter which is substantially uniform throughout a swath of the scene swept by a detector while leaving image points of relatively small objects unaffected by the gain normalization. The display is relatively free of nonuniformities associated with differing responsivities of the detectors to infrared radiation.

摘要： An electronic document delivery system and method in which a broadcast center (150) periodically sends a "catalog" of available documents to a receiving computer (110), thereby allowing a user to browse through the available documents without having to access the broadcast center (150). The documents are transmitted as packets, and the packets are decrypted as soon as they are received, eliminating the need to store both an encrypted and a decrypted version of the documents at the receiving computer. The receiving computer (110) periodically receives information allowing it to decrypt received documents and to encrypt billing information for the receiving computer. The invention is not limited to text-only documents, and can receive all types of documents, such as software, images, text, and full-motion video.

摘要： A dielectric material is formed into a structure having two parallel broad surfaces with one or more raised integral portions extending transversely across at least one of the broad surfaces. The exterior is uniformly conductively coated resulting in a parallel plate waveguide having a continuous transverse stub element disposed adjacent one plate thereof. Purely reactive elements are formed by leaving the conductive coating on the terminus of the stub element, or by narrowing the terminus of the stub element. Radiating elements are formed when stub elements of moderate height are opened to free space. Radiating, coupling and/or reactive continuous transverse stub elements may be combined in a common parallel plate structure in order to form a variety of microwave, millimeter wave and quasi-optical component including integrated filters, couplers and antenna arrays. Fabrication of the dielectrically-loaded continuous transverse stub element can be efficiently accomplished by machining, extruding or molding the dielectric structure, followed by uniform conductive plating in order to form the parallel plate transmission line. In the case of antenna applications, machining or grinding is performed on the stub terminus to expose the dielectric material at the end of the stub element.

摘要： Surface-emitting distributed feedback (SEDFB) lasers (10) having a curved grating (30) with a shape that produces good beam quality. A preferred shape is one for which the grating curves away from the center of the gain region (31) of the laser (10). The use of the curved grating (30) of the present invention produces good beam quality from broad area SEDFB lasers with high power and high efficiency. The present invention overcomes self-induced filament formation and dynamic instabilities that limit achievable beam quality. The present invention provides for a holographic method for fabricating curved gratings (31) for the SEDFB lasers (10) that is consistent with laser batch processing.

摘要： A spacecraft power bus regulation method and apparatus for a spacecraft. The spacecraft has solar arrays (10) and a battery (30) coupled to the spacecraft power bus (32) to drive electrical loads (34). A bus voltage limiter (38) controls the flow of current from the solar arrays while a bidirectional battery controller (36) controls power flow into and out of the battery. A processor (46) monitors current flow and battery condition using sensors (40, 42, 44, 48) and controls the bus voltage limiter accordingly. Auxiliary control is provided by the solar array drive (24) which controls the orientation of the solar arrays with respect to the sun.
