Title: Rotor recognition system
Inventor: ROMANAUSKAS WILLIAM A
IPC: G01B15/04
Filed: 1987-12-10
Granted: 1992-11-17
Abstract: ROTOR RECOGNITION SYSTEM            ABSTRACT OF THE INVENTION         A transmitter and associated receiver interrogate the surface of a rotor at one or more radial positions from the center of rotation using emitted pulses of energy.  Signature signals representative of the distance traveled by the pulses collectively form a signature signal pattern which is compared to a reference library of such signature signal patterns.

Filed: 1988-03-03
Granted: 1991-05-21
Abstract: ABSTRACT          Particulate material from a conveyor belt may be removed by a conveyor belt scraper comprising a flexible wear element for bearing against the working surface of the conveyor belt and a housing shaped and dimensioned for dispensing one end of the wear element against the conveyor belt and for storing the rest of the wear element in the interior of the housing.  The transverse dimensions of the interior of the housing are less than the length of the wear element.  The housing is pressure-tight up to a given operating pressure when the wear element is within the housing.  The housing is adapted to be filled by a fluid, such as a gas or liquid, which when compressed acts directly on the wear element within the housing to force the wear element against the conveyor belt and to maintain the wear element against the conveyor belt as the wear element wears.

Abstract: The automatic compensation system, denoted by the abbreviation AFC, is a monobloc assembly which is totally insensitive to turbulence. According to the first part of the improvement, the system consists of two force sensor-comparators (1) mounted in series and providing for the fully automatic adjustment of the compensator as a function of the thrusts produced on the flywheel or rudder control bar whatever the attitude, height or speed. The system is completely adapted to the kinematics of the control circuits, whether rigid or cabled. The AFC is completely insensitive to three-dimensional accelerations and is noteworthy in that it also forms the basis of the system for validating orders given to the throttle control through the automatic control system which is the subject of the second part of the improvement and is denoted by the abbreviation AED. This automatic control system consists of a memory disc with double recording speed and transfer sectors allowing optoelectronic power regulation which is insensitive to turbulence for each memorised speed in a range from the initial approach speed (1.2 VS1) to the speed that must never be exceeded (VNE). <IMAGE>

Granted: 1999-04-13
Abstract: An apparatus and a method for profiling the intensity of a beam and thus measuring the overall intensity and power of a beam are disclosed that have particular use in stereolithography.  A beam sensor comprising a pinhole in a plate and a photodetector behind the pinhole measures the intensity of portions of a beam as the beam is moved over the beam sensor.   Software  associated with the sensors in a computer controls the scanning mechanism for the beam so that the beam is shifted to find the pinhole and move across it in order to develop the intensity profile.  The invention can be used to detect drift in the scanning mechanism, determine the focus of the beam, and predict the depth and width of photopolymer cured by the beam.  A related apparatus and method for calibrating and normalizing a stereolithographic apparatus is described, and a related apparatus and method for correcting for drift in production of objects by stereolithography, is also described.
