Title: An active sonar system for target detection in the presence of strong main lobe interference
Inventor: FEINTUCH PAUL L
IPC: C08G63/19
Filed: 1990-07-27
Abstract: An active sonar system and method of processing sonar signals which provide for target detection in the presence of main lobe interference. The system comprises a transmitter which transmits a plurality of uniquely encoded sonar signals in a plurality of angular directions. A receiver detects echoed target return signals and plane wave interference signals having different signal strengths transmitted from sources located at unknown angular directions. The receiver comprises a first processor including a plurality of adaptive filters arranged as a Gram-Schmidt spatial predictive canceler. The canceler produces an output signal having a spatial response which has nulls located in the angular directions of the interference sources. The nulls are proportional to the respective signal strengths of the interference sources. A second processor processes the output signal from the Gram-Schmidt predictive canceler by means of a plurality of filters matched to the plurality of unique codes contained in the target return signals. The second processor provide a plurality of matched filter output signals which are indicative of the signal strength and angular location of the targets. The existence of a detected target is determined by each matched filter whose output signal is above a predetermined threshold, and the angular direction of each target corresponds to the direction that the corresponding encoded sonar signal was transmitted.

Abstract: In accordance with the present invention, Parmesan cheese is grated to provide a particulate Parmesan cheese. The grated Parmesan cheese is dried to a moisture level of from about 19% to about 24% by weight. Either before or after the drying step, disodium phosphate is blended with the grated Parmesan cheese.      After a period of time, the disodium phosphate is dissolved into the grated Parmesan cheese. After dissolution of the disodium phosphate, the Parmesan cheese particles remain discrete and the Parmesan cheese particles resist agglomeration and oil-off even at moisture levels of from about 19% to about 24% and at temperatures higher than ambient.

Title: Power factor maintenance system
Inventor: ENGELMANN RUDOLPH H
IPC: H02M1/00
Filed: 1990-11-30
Abstract: ABSTRACT In an AC-to-DC converter, a switched inductor, in the form of a ringing-choke or flyback DC-to-DC power converter, is interposed between the AC line input rectifier and the DC storage capacitor. In accordance with the relationship Inductance/Time equals Voltage/Current the inductance and on-time of the switched inductor are held constant so that the instantaneous input voltage and current maintain a directly proportional relationship, thereby imparting a resistive characteristic to the input impedance -- i.e, the input reactance vector is held to near zero rotation. Hence, the input power factor is held close to unity. Means are included for varying the values of the inductor and/or time in response to changing load requirements.

Title: Optical amplifier with bent, single-mode active fiber
Inventor: GRASSO GIORGIO
IPC: H01P1/16
Filed: 1991-01-23
Abstract: An optical amplifier, particularly useful for optical fiber telecommunication lines, which includes an active fiber doped with a fluorescent dopant which provides light energy emission at the wavelength of the transmission signals when the latter signals are applied thereto.  One section of telecommunication line is connected to one input of a dichroic coupler, the output of which is connected to one end of the active fiber and the other input of which is connected to a source of pumping energy at a wavelength lower than that of the transmission signals.  The other end of the active fiber is connected to another section of the telecommunication line.  In rectilinear form, the active fiber provides single-mode propagation of the energy at the signal wavelength and multi-mode propagation of energy at the pumping energy wavelength.  However, the active fiber is bent to a radius of curvature for at least 70% of its length which will provide only fundamental mode propagation at the pumping energy wavelength which also reduces the mode diameter for the transmission signals.

Title: Order independent rule-based program specification system
Inventor: KAPAUAN PRUDENCE T Z
IPC: G06F9/06
Filed: 1991-02-07
Abstract: ORDER INDEPENDENT RULE-BASED PROGRAM SPECIFICATION SYSTEM Abstract A method is disclosed of providing instructions to a compiler system for specifying rules of behavior for a program.  Rules are implemented by a message passing structure, wherein messages are passed between objects of the system.  Each rule is defined by a structured script identifier, that uniquely characterizes the timing, level of detail and the grouping of a rule.  Each rule is further defined by preconditions that determine when the rule applies, and the state of the system after it has been applied (postconditions).  The behavior of a program can be specified so that rules can be applied to a system based on timing constraints, and/or in a logical order, based on the occurrence of logical conditions.  The rules are executed bytesting for preconditions subject to timing constraints, and asserting postconditions when the preconditions have been satisfied.  Each rule has an attached label specifying a level of detail. Testing of the rules can be performed and displayed at any specified levels of detail.

Abstract: An X-ray image pick-up method causes X-rays from an X-ray source to be irradiated on an object for picking up its image as passed through a filter capable of restricting any fluctuation in effective X-ray energy within +10%, and then the X-rays thus penetrated through the object to be picked up by an image pick-up means. Radiation dose with respect to patients as the object and eventually to doctors or X-ray operators is thereby minimized, while the image pick-up can be realized with a high resolution.

Abstract: ABSTRACT           A hose coupling wherein the terminal portion of a rigid metallic or plastic pipe has one or more external annular retainers close to its free end and is surrounded by a sleeve-like layer of sealing material, such as synthetic rubber, which retains its sealing properties within the entire temperature range of between approximately -80°C and +260°C.  The terminal portion of the pipe and its layer of sealing material are inserted into the terminal portion of a hose prior to the application of an annular clamp which surrounds the terminal portion of the hose and urges it against the external surface of the layer of sealing material. The retainer or retainers are located between the properly applied clamp and the free end of the terminal portion of the pipe.  The layer of sealing material can but need not extend beyond the clamp, e.g., all the way to the free end of the terminal portion of the hose, and the materials of the hose and layer are selected in such a way that the sealing material does not adhere to the hose.  The sealing material of the layer adheres to the terminal portion of the pipe.
