摘要： A photoelectric sensing unit, especially useful for determining the passage of clear bottles or other low contrast targets on a conveyor, contains two sensors and a signal processing unit to determine the signal differential. The signal differential is compared to a selected value and sensor output is enabled or disabled. High noise immunity, resistance to target reflection, and output reliability result. The unit may correct the selected value to account for environmental change and/or unit component performance. The unit can also figure the speed of passage of the bottles.

摘要： A light curtain device for creating a curtain of light between a reflective first location and a second location is disclosed. The device includes a light source adapted to provide a light column, a plurality of beam splitters, a plurality of light detectors, and an indicator arranged to indicate the interruption of the light column. The beam splitters are disposed to intersect the light column at intervals, and each of the beam splitters is adapted to direct a deflected portion of the light column toward the first location. The reflective first location receives the deflected portion of the light column from each of the beam splitters and reflects each deflected portion toward the second location. The light detectors are disposed adjacent the second location, with each of the light detectors being operatively associated with a corresponding one of the beam splitters and being positioned to the receive its corresponding deflected portion reflected by the reflector.

摘要： A photodetector is provided with two light sources and a light sensitive component. The use of two light sources significantly reduces the opportunity of a surface feature, or abnormality, from focusing light back toward the light sensitive component in a manner that could possible cause the photodetector to misinterpret the intensified light as being indicative of the absence of an object in the detection zone. The light sources and light sensitive component can be arranged along an axis which is either parallel to the path of the objects to be detected or perpendicular to their path.

摘要： A method and apparatus for sensing a presence of a magnetic field and/or a magnitude of a magnetic flux density of the magnetic field. A direct-current voltage is applied across a first layer of a conductive material, so that a direct current flows in a first direction through the first layer. A second layer of a piezoelectric material is integrated with or positioned adjacent or abutting the first layer. The first layer and the second layer are exposed to or positioned within a magnetic field. A Lorentz force is thus caused, preferably in a direction which is generally perpendicular to the first direction of the direct current and a second direction of the magnetic field to deflect the piezoelectric material thereby causing an output voltage in response to the Lorentz force. A magnetic flux density can be calculated as a function of the piezoelectric output.

摘要： An optical system is adapted to produce reduced back reflection from a receiving detector back to a light source for increased system performance. The system may optically condition light signals from the light source for projection onto the detector. The conditioning may result in a light spot on the detector that has an annular intensity distribution or profile. The annular distribution may be attained in any number of ways including providing a slope discontinuity in the lens surface, providing an ax icon lens function, and/or providing a defocused light spot on the detector surface.

摘要： An optical system for high speed transmission of optical data. The system may condition light signals from a source for projection into an optical medium that is to convey the signals with high speed to another place. This conditioning may result in the light having an annular intensity distribution or profile. Much of the intensity of the light is near the periphery of the optical medium. This medium may be an optical fiber. This annular distribution may be attained with an optical element having a slope discontinuity or light from it being defocused to a certain extent at the optical medium. Either of these characteristics or both of them may used in the optical system so it can transmit light signals at very high rates.
