Title: Detection of spread spectrum signals
Inventor: HOUGHTON ANDREW WARREN
IPC: G01S3/04
Filed: 1995-09-20
Abstract: A spread spectrum signal detection system comprising two spatially separated receivers, a correlator, such as a time integrating correlator employing acousto-optic cells, which is connected to the outputs from the two receivers to produce a signal representative of the cross correlation function of the two spread spectrum signals, a filter arranged to transmit only the central portion of the cross correlation function and a signal processor to produce the cross spectral density and thereby determine the presence of the spread spectrum signal. The direction of arrival of the spread spectrum signal can be determined by measurement of the angle of the phase slope of the cross spectral density. The acousto-optic cells can be Bragg cells. The output signal from one of the receivers can be applied to a first Bragg cell arranged to point modulate light from a laser light source, the output then being transmitted through a beam expander to a second Bragg cell to which the output signal from the second receiver can be applied, the output from the second Bragg cell then being detected by a photo-detector array. The output from the second Bragg cell can be spatially filtered by providing adjustable imaging optics arranged such that only light corresponding to the central portion of the cross correlation function is transmitted. The processor can be arranged to demodulate the signals to produce data corresponding to the central portion of the cross correlation function and to Fourier transform the data to produce the cross spectral density.

Title: Method and apparatus for controlling propagation of electrical charges using multiple coherent light beams
Inventor: VAN DRIEL HENRY MARTIN
IPC: G02F1/01
Filed: 1997-08-13
Abstract: A method and apparatus for generating and controlling the propagation of electrons in a semiconductor material using a plurality of beams of coherent light is disclosed. The direction and magnitude of propagation of the electrons in the semiconductor are controlled by varying the polarization of the coherent beams with respect to the semiconductor material, and in particular the crystallographic axis of the semiconductor material.  The electrons are generated and controlled by use of three coherent beams which are related such that the frequency of one of the beams is substantially equal to the sum of the frequencies of the other beams, and the first beam produces substantially the same number of electrons in the semiconductor material that the other beams produce together.  A selected region of the semiconductor material is simultaneously irradiated with all of the beams of light.  The semiconductor material is at approximately room temperature.  Holes are also generated and propagate in a direction opposite to the direction of propagation of the electrons.

Abstract: The movable contact arms of a circuit breaker are latched in the blow open position to prevent rebound and possible restrike of the arc in response to the very high magnetic repulsion forces generated by a short circuit in the protected electrical system.  Each movable contact arm is mounted on a secondary carrier coupled to a main carrier by a spring loaded cam mechanism which allows the movable contact arm to blow open before the main carrier is rotated to the open position by the spring driven circuit breaker operating mechanism.  In one embodiment of the invention, the movable contact arm is latched in the blow open position by a  latching detent  in  the  cam surface  of  the  cam mechanism.  In a preferred embodiment, the secondary carrier is latched by a detent formed by a leaf spring cantilevered from a fixed support.   Subsequent rotation of the main carrier by the operating mechanism releases the latch by rotating the secondary carrier clear of the detent formed by the leaf spring.

Abstract: The present invention relates to sports posts such as net posts, goal posts and posts for athletics, which are light, tough, easily set up or taken down and, moreover, excellent aesthetically.  The sports posts relating to the present invention are sports posts which are characterized in that two or more fibre reinforced plastic hollow tubes are fitted and connected together and, furthermore, a screw-type extension and retraction mechanism is built in; and preferably, they are the sports posts according to Claim 1 where a rod shaped member fixed to one hollow tube passes through the through-hole of an element fixed to another hollow tube. Again, another embodiment of the present invention comprises sports posts in which the said reinforcing fibre layer from which the hollow tubes are composed primarily comprises a laminate structure of sheet-shaped material of said fibre; and preferably, sports posts comprising a laminate structure of a sheet shaped material in which said fibre is carbon fibre and filaments thereof are unidirectionally arranged, and of a filament bundle structure layer which can be seen from outside. With the sports posts of the present invention, a considerable reduction in weight is achieved while still maintaining the strength to withstand a large bending moment and, at the same time, by employing a special mechanism for preventing co-rotation, without severing the reinforcing fibre and without any loss in the inherent strength of the tube, there is realised an extension/retraction function and the effects stated at the top of the page are achieved.

Abstract: The invention concerns a method for generating a yarn composed of at least two yarn components and an apparatus for generating a yarn of this type with at least two processing stages at least one of which is a compacting stage.   A yarn component is supplied either as a filament bundle from an extrusion beam or as a filament bundle or as a staple fibre yarn from a package.   Treating stages are designated with the reference number (2) and the compacting stage with the reference number (3) in which compacting stage the individual yarns (5 through 5.4) are compacted into a yarn (7), which subsequently is collected in a collecting stage where it is e.g. wound into a package.   The Fig. 2 differs from the Fig. 1 in that one yarn component is treated differently, or is not treated, respectively, where e.g. the yarn (5) undergoes the same treatment as in the Fig. 1, whereas the yarn (5.5) is subject to two treatments and the yarn (5.6) upstream from the collective compacting stage (3) is left untreated. Correspondingly the character of the yarn (7.1) differs from the character of the yarn (7) according to the Fig. 1.

Abstract: A co-channel interference canceler and a method therefor. The co-channel interference canceler includes: a co-channel interference rejection filter for outputting a second input signal by removing co-channel interference from a firs t input signal; a first post processor for removing interference other than co-cha nnel interference from the second input signal; a second post processor for removing interference other than co-channel interference from in the first input signal; and a selection controller for selecting the output of the post processor which has le ss error by comparing the output of the first post processor with the output of the second post processor. Therefore, other interference such as ghost and phase noise included in an input signal are removed or reduced via the extra second post processor which is different from the first post processor of the signal pa th. The selection of the NRF is controlled using the signal from which other interference has been removed or decreased, thereby minimizing the effects of th e other interference. As a result, error in selection of the NRF, which may be caused by the other interference, can be prevented, and selection of the NRF is reliably controlled.
