An analyser (16) is used detect such disturbance by measuring changes in the phase of the received signal (19).

Abstract: A financial statement module is provided in which information concerning transactions is stored efficiently in order to produce small files and be able to store a large quantity of transaction information. Using the distinction and processing done to the two types of balances appearing in the financial statement, the module can produce any type of financial statements, independently of the type of business, report, accounting system or information. The generator can produce a detail for a financial statement item, for an account balance, for a document, and build any transactions report. Using the financial statements created, anyone can evaluate the economical performance of the individual or business concerned because the emphasis of the report is chosen by the user without any conventional frameworks, and perform verification work.

In one aspect, a diagnosis method comprising analyzing a stool sample of an individual for the presence of a biological marker wherein the quantity of the biological marker is an indication of whether the individual has, or can develop, a dysautonomic disorder or dysautonomic condition, as well as a therapeutic method for treating a dysautonomic disorder or dysautonomic condition by administration of, e.g., secretin, neuropeptides, peptides and/or digestive enzymes.

Abstract: Techniques for detecting an island in a system including a node that is operatively coupled to a primary power source (e.g., grid) and one or more distributed power generation sources are disclosed. In one embodiment, a current pulse is included in the output of a distributed power source. The grid voltage is monitored at the node to determine if a pulse-related disturbance occurs. If the grid is present, no pulse-related disturbance will manifest. If grid is down, then a pulse-related disturbance will manifest. Detection of the pulse-related disturbance is used to signal island detection.

Abstract: An algorithmic approaches that can be implemented in software/firmware/hardware that filters out stable PRI patterns detected within a system that is prosecuting against radar based transmissions are disclosed. The algorithms allow downstream computing assets to concentrate their limited resources on the more complex emitter PRI pattern types. Thus, a portion (e.g., stable signals) of the pulse deinterleave and PRI identification problem is solved without requiring the more computationally expensive processing. The disclosed algorithms can be employed, for example, in electronic support measures (ESM) systems, electronic intelligence (ELINT) systems, and/or a electronic countermeasures (ECM) systems. The algorithms employ linear detection, linear regression, or a combination of linear detection and linear regression, thereby providing a “dual voting” scheme that decreases the occurrence of false positives.

There may be an alignment bar on the drum, not higher than flush. There may be a recess behind the bar for the leading edge of the sanding sheet.

Abstract: Techniques for determining the angles of arrival of multiple simultaneous cochannel sources using only a single RF receiver sampling and downconversion channel is disclosed. This is accomplished by sequentially forming several known mixtures of multiple antenna signals in the RF domain prior to downconversion and digitization. Angle of arrival information is then recovered through the application of higher order statistics and subspace fitting techniques. The same principles can be applied to other P-element receiver arrays (e.g., acoustical receiver array).

Abstract: Techniques for reading data from a storage medium (150) having a high track density prone to adjacent track interference are disclosed. One or more sensing elements (120) are used to extract data stored on adjacent tracks. Multiuser detection (130) is then used to detect/decode a single track that is closely spaced to its neighboring tracks, resolve interference from adjacent tracks, or to simultaneously detect/decode multiple adjacent closely packed tracks.

Abstract: A compact fixturing means is disclosed that delivers two or more phase tracked channels of high power (e.g., 1000 Watts) to an antenna that can produce a multiplicity of polarization depending on the phase relationship of the delivered signals. Coaxial cables are used as a service loop to provide two or more channels of phase tracking and high power signals to the multi-polarized antenna. A flat spiral spring is configured within the fixture to the guide two (or more) coaxial cables along a spiral loop to allow approximately equal tension on the cables as the fixture is rotated. The flat spiral spring is operatively coupled to a rotation plate and progresses form an inner radius proximate the fixture input to an outer radius proximate the fixture output.

Abstract: A system is disclosed for the absorption of an impact, that system comprises a blow molded thermoplastic energy absorbing member. The blow molded thermoplastic energy absorbing member provides opposing first and second walls defining a hollow space; according to one embodiment, a plurality of fused and unfused recessed ribs integrally molded between the first and second walls. The fused recessed ribs have a fused recessed rib end. The fused recessed rib ends are integrally fused to either opposite recessed rib ends or the facing opposite wall at a welded surface such that the height of the recessed ribs from the first wall to the welded surface is about approximately 15.0 to 45.0 mm. The recessed ribs are, according to one embodiment, connected by a plurality of straight interlocking ribs.

Abstract: A supercritical fluid cleaning system uses process fluid for operating rotary motors in the chamber with fluid bearings and fluid load levitation for rotating workpieces and impellers. Rotating speed and direction sensors and a home position locator facilitate motor control. Impellers add further agitation of the fluid in the chamber, faster processing, and greater uniformity of supercritical fluid components and increase mass transfer of fluid to the processed surface. Centrifugal operated clips and cassettes hold wafers and impellers. Non-contact, fluid operated rotating mechanisms reduce contamination. Physical, rotational, and shear affects are enhanced through centrifugal forces which can induce the separation of films localized deposits or molecular products of the reaction from the surface. There is a concomitant agitation of fluid, and continuous angular acceleration imparted to the processed surface features.

Abstract: Techniques for switching an optical element from one path to another, where each path has high dimensional stability in a harsh thermal and dynamic environment, are disclosed. In one particular embodiment, the optic is mounted on a rotable platform. A spring mechanism preloads the platform against a hard stop, thereby providing accurate and repeatable placement of the optic in its deployed position. The motor's actuator arm is the only element whose position is sensed, allowing the switching system to work without requiring highly precise position feedback. In the stowed position, the spring mechanism operates as a firm tension cable, thereby securing the optic out of the laser beam path.

Abstract: A miniature broadband monopole antenna design configured with integrated band-selecting filtering is disclosed. The antenna is electrically folded, and includes top and bottom monopole sections, with a meanderline to provide an inductive load between the two sections. The overall antenna structure can be embedded in a relatively small, RF transparent, composite structure (e.g., such as the fin of a guided munition), and has minimal impact on aerodynamics (low drag). The top, bottom, and meanderline elements of the antenna operate together to collectively provide multi-band operation (e.g., 30 MHz to 3 GHz).

Abstract: An error correction decoding (ECC) processing scheme is disclosed that reduces computational complexity normally associated with multiuser detection (e.g., TurboMUD) solutions, without causing degradation in quality of service or decreasing the total throughput. Error correction decoding algorithms are applied only to portions of the estimates that were affected by the immediately previous MUD update process. Even though the MUD and/or ECC updating is targeted so as to reduce complexity of each iteration, all of the estimates are maintained and remain candidates for future updates. As such, there is no negative impact real-time or future performance. This targeting approach can be used in conjunction with many variations of MUD, including full-complexity or reduced complexity, and may include MUD with confidence ordering or voting, and other techniques for facilitating efficient and effective MUD processing.
