Abstract: A receiver which receives signals transmitted at different symbol rate and variably sets the pass band width of a filter which eliminate unnecessary signals from the output of a detector in accordance with the symbol rate reproduces clocks synchronously with the switched symbol rate without generating discontinuity even when the symbol rate is changed by compensating the variation of delay caused when the pass band width of the filter is changed.

Abstract: The method for switching optical radiations having orthogonal polarizations, consisting in that a linearly polarized pumping is applied to the input of a birefringent object (4) (optical waveguide or crystal), and orthogonally thereto is applied a polarized optical signal having a maximum intensity of I s,max  which is by at least one order of magnitude lower than the pumping intensity, the polarization vector of the linearly polarized pumping or of the signal is directed along an optical axis of the object thereby eliminating a linear coupling between the waves of orthogonal polarizations, and the pumping intensity is selected to be higher than the threshold value which is found from the following formula:           I       p           >2|θ|       -1       [α| ,             where
     θ - is the cubic nonlinear coefficient (factor) of the object;               α = n       O           -n       e              - a difference between the effective refractive indices of orthogonally polarized radiations,    and the intensity of the optical signal radiation is varied from zero to a maximum value of  I   s,max <0.1 I   p .
     The device for carrying the proposed method into effect, comprises a birefringent object (4) (optical waveguide or crystal), a source (1) of optical pumping radiation linearly polarized either along the optical axis of the object or normal to the mentioned optical axis, a source (2) of an optical signal polarized either normal to the mentioned optical axis of the object or along it, a mixer (3), where the signal radiation and the pumping radiation are spatially coincided, and a polarizer (5) spatially separating radiations of orthogonal polarizations, the intensity of the optical pumping radiation introduced into the object (4) is selected to be higher than the mentioned threshold value.

Abstract: A method and system (50) for tracking the position of
a moving transmitter using angle of arrival measurements
from direction finding antenna arrays (60, 70). Each array
includes several elements (60A-60N, 70A-70N), with the
elements grouped to provide subarrays of different element
spacings which are multiple of one half the transmitter
wavelength. Ambiguity is rejected by processing angle data
received from the subarrays. The signals from the arrays
are processed to convert electrical phase delay into
spatial angles, the spatial angle data is processed to
provide the x,y position, velocity and acceleration of the
transmitter. For transmitters mounted in moving vehicles,
the system further processes the x,y data and applies a
quality weighting factor that filters out multipath factors
and permits estimation of vehicle profile information.

Abstract: A traceable well cement composition is comprised of hydraulic cement, sufficient water to form a pumpable slurry and a normally non-radioactive vanadium compound tracer which becomes radioactive and emits detectible rays over a relatively short time period when exposed to neutrons. In cementing a zone in a well and subsequently detecting the subterranean location of the cement composition therein, the traceable well cement composition is introduced into the zone to be cemented. Neutrons are then emitted from a source in the well so that the tracer compound emits detectible rays, the rays are detected and the location of the cement composition in the well is determined.

Date Jan. 23, 1997The invention concerns a method and measuring device for determining the water content of a gas. The measuring device comprises a measuring sensor arrangement which consists of: a capacitive sensor thermally coupled to a heating element and to a temperature sensor; an energy source connected to the heating element; a first evaluation circuit connected to the temperature sensor. The heating element and the temperature sensor are formed by a common temperature-dependent resistor. Together with the temperature dependent resistor and the energy source, the second evaluation circuit forms a control circuit for keeping the temperature of the capacitive sensor constant. As a function of the capacity of the capacitive sensor as the sole variable the first evaluation circuit determines the actual value of the relative humidity of the gas from previously determined calibrating values at the same constant temperature by interpolation or extrapolation of the calibrating values.
