Abstract: The invention relates to a sensor element made of thin film components and fiber glass, and a support structure (7) made of fiber glass; when the sensor elements are attached to the support structure (7), a sensor system suitable for magnetoencephalographic measurements is formed. A substrate containing a planar signal coil and a SQUID is attached on a circuit board made of fiber glass using a spring cut on the edge of the body plate. On the sensor element, there is a small but mechanically stable connector or several such connectors (5); when the sensor element is plugged in the receptacles (6) on the support structure (7), the element settles in a well defined orientation. The support structure (7) is made of a fiber glass shell following the shape of the bottom (10) dewar vessel, adapted to the shape of the head. The receptacles (6) are attached to the glass fiber shell by means of springs (9) made of thin fiber glass plate in such a way that an array covering the whole skull as evenly as possible is formed when the sensor elements are plugged to the receptacles (6). The spring is cut in a way to enable rotation only around an arbitrary axis in the plane of the spring and a translation only in a direction perpendicular to the plane of the spring. When this support structure is inserted in the dewar, the individual sensor elements lean against the dewar bottom (10) by aid of three feet (11), pressed by springs (9), settling perpendicularly to the normal of the dewar bottom passing through the center of the sensor element. <IMAGE>

Abstract: A method of producing self-supporting ceramic composite bodies of desired shaped by infiltrating a permeable preform with polycrystalline matrix material consisting essentially of an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents. The composite body is formed by contacting a zone of a permeable preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product. Within a certain temperature region, and optionally with one or more dopants in or on the parent metal or said permeable preform, molten parent metal migrates through previously formed oxidation reaction product into contact with the oxidant, causing the oxidation reaction product to grow into the preform toward said defined surface boundary so as to infiltrate the preform up to said defined surface boundary, and provide the composite structure of desired geometry.

Title: Echo canceller having fir and iir filters for cancelling long tail echoes
Inventor: KOIKE SHIN ICHI
IPC: H04B3/23
Filed: 1990-02-22
Granted: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE An echo canceller comprises a finite impulse response filter (6) connected to the incoming port of a hybrid (1), and a tail canceller (7) which includes an infinite impulse response filter (24; 40) having a multiplier (14; 33) for recursively multiplying an output digital symbol from the tapped-delay line (8) of the FIR filter with an attenuation coefficient R. A digital symbol from the IIR filter or one from the tapped-delay line (8) is multiplied with a tap-weight coefficient Ci and summed with the outputs of tap-weight multipliers of the FIR filter to produce a replica of an echo symbol, which is subtracted from a digital symbol yn from the outgoing port of the hybrid (1), producing a residual echo symbol en. The coefficient Ci is derived from correlation between residual echo en and a symbol from the tapped-delay line. In one embodiment, symbol from the tapped-delay line is further delayed (17) for a unit interval on the one hand, and multiplied (18) with coefficient R on the other, the difference between them being detected (19) and multiplied (20) with a coefficient K, which is either sgn(Ci) or 1/Ci, to generate a multiplied difference. Correlation is detected (22) between the difference and residual echo en to derive the coefficient R. In a second embodiment, symbol from the tapped-delay line is further delayed (36) for a unit interval and multiplied (37) with K to produce a delayed-multiplied symbol. Correlation is detected (35) between it and residual echo en to derive the coefficient R.

Granted: 1995-05-09
Abstract: Weather simulation is a modular addition to a digital radar landmass simulator (DRLMS).  The DRLMS is a four channel system, i.e., culture, elevation, aspect and weather.  All four channels are integrated to provide a simulated radar landmass simulation with weather.  Implementation entails the full or partial occultation of terrain and targets by weather and vice versa.  Weather mass is simulated in three dimensions; that is, it has a bottom and height.  The weather mass is not made of simple geometric objects.  Weather maps can be loaded into the system as weather patterns, and the weather patterns can be expanded, rotated and translated.  In addition, the weather channel can be used to simulate chaff and jamming patterns.

IPC: H04N7/50
Filed: 1991-11-06
Granted: 1996-09-03
Abstract: In a differential PCM encoder, the problem of error perpetuation is solved by leaking a changing, rather than a fixed, fraction of the input signal to the differential PCM. The fraction leaked is sensitive to the characteristics of the signal. In one embodiment the fraction leaked is fixed for a frame in accordance with a chosen characteristic of the frame signal. In another embodiment, the fraction leaked is set in accordance with one function when a chosen characteristic of the frame signal exceeds a given level, and follows another function when the chosencharacteristic does not exceed the chosen level. In a still another embodiment, the fraction leaked is set to one of two levels, based on a chosen characteristic of the frame signal.
