摘要： Physical quantities such as pressures, accelerations and electrical currents including d-c currents are measured by alternately passing polarized and unpolarized light through an optical-sensor which modifies the polarization of the polarized light in proportion to the magnitude of the physical quantity while passing the unpolarized light unaltered by the physical quantity. The polarized and unpolarized light are generated by separate light sources which generate light at two different wavelengths and a polarizer which is effective to polarize light of the one wavelength but not the other. Light emerging from the sensor is converted into an electrical signal by an analyzer and a photodetector. The intensity of the light generated by the two sources is adjusted so that the electrical signal generated in response to the polarized light is substantially equal to that generated in response to the unpolarized light so that by subtracting the signal generated by the unpolarized light from that generated in response to the polarized light the component of the later proportional to the magnitude of the physical quantity is extracted. The subtraction is effected in an exemplary embodiment by comparing the electrical signal to a reference signal and adjusting the intensity of the unpolarized light to drive the difference between the electrical signal generated by the unpolarized light and the reference signal to zero, and then using the difference between the electrical signal generated by the polarized light and the reference signal as the output proportional to the magnitude of the physical quantity.

摘要： A drift free magneto-optic current transformer for measuring an electric current which may include a d-c component in which two orthogonally polarized light beams are passed through a magneto-optic element operating as a Faraday rotator to rotate the beams through an angle dependent upon the magnitude of the d-c current. An analyzer, oriented with two orthogonal polarization axes set at +45 degrees and -45 degrees with respect to the plane of polarization of the first input light beam and at -45 degrees and +45 degrees with respect to the plane of polarization of the second input light beam, splits each emerging light beam into two output light beams which are converted into a.sub.1 and b.sub.1, and a.sub.2 and b.sub.2 electrical signals in response to the first and second input light beams respectively. By maintaining the signal (a+b).sub.1 equal to (a+b).sub.2, and by maintaining (a-b).sub.1 +(a-b).sub.2 equal to zero, an output signal (a-b).sub.1 -(a-b).sub.2 proportional to the magnitude of the d-c current, and free from drift due to changes in the attenuation characteristics of the optical components, is obtained without the necessity of dividing by a variable.

摘要： A thin film electroluminescent edge emitter structure includes a common electrode layer and control electrodes disposed above the common electrode layer. At least one dielectric layer is disposed between the common electrode layer and control electrodes, and a phosphor layer is interposed between the one dielectric layer and common electrode layer. The common electrode layer, one dielectric layer and the phosphor layer define the light-emitting pixels of the emitter structure. Each pixel has a light-emitting face formed thereon and is operable upon application of electrical excitation to cause the radiation of light energy within its phosphor layer at least in a direction towards the pixel light-emitting face. An optical lens system associated with the pixels includes a preselected contour shaped on the light-emitting face of each pixel to define an optical lens integral therewith to project the light energy passed therethrough in a preselected direction and form a beam of light energy having a preselected beam pattern. A multi-color light emission system employed by the pixels includes a plurality of phosphor zones composing the phosphor layer and capable of projecting different light energy through the light-emitting faces of the pixels. Also, separate edge emitter structures projecting different colors of light can be utilized in a electrophotographic printer.

摘要： A device for detecting insulation defects in a cable having a conductor while an electrical signal is impressed on the cable conductor, the device being composed of an ion source for generating an ion cloud and arranged for causing the ion cloud to be displaced along, and to envelop, the cable, a sense conductor arranged to be disposed along, and in proximity to, the cable and to be in communication with the ion cloud, and a plurality of coded position conductors arranged to be disposed along, and in proximity to, the sense conductor and to be in communication with the ion cloud, each position conductor having at least one discrete region covered with insulation arranged in a pattern which differs from one position conductor to another. An alternating signal having a respectively different frequency is applied to each position conductor, the frequency of the signal impressed on each position conductor being different from the frequency of the signal impressed on the cable conductor. When the ion cloud envelops the conductors and a region of the cable insulation which contains a defect, signals present in the cable conductor and the position conductors are coupled into the sense conductor. The signals impressed on the cable ocnductor and on each position conductor are synchronously detected with respect to the signals coupled into the sense conductor to provide an indication of the existence and location of cable insulation defects.

The electronic interface further includes a compensation memory for compensating for pixel variations in the TFEL structure. The compensation memory can be periodically recalibrated "in place" during the life of the printing apparatus.

摘要： A TFEl structure has a multi-layer construction which includes a bottom substrate layer, a lower electrode layer, a middle EL stack, and an upper electrode layer. Forward portions of the EL stack and the lower and upper electrode layers have formed therethrough a series of longitudinal channels and a transverse street connecting the channels and extending along a forward edge of the bottom substrate layer so as to define a plurality of pixels having light-emitting front edges setback from the forward edge of the bottom substrate layer by the width of the street. Rearward portions of the lower and upper electrode layers respectively underlie and overlie a rearward portion of the EL stack but not each other so as to electrically isolate the rearward portions of the lower and upper electrode layers from one another. Also, a bus bar layer overlies the rearward portion of the EL stack and crosses the rearward portion of the upper electrode layer. An insulation layer is interposed between the rearward portions of the bus bar layer and upper electrode layer. Selected portions of the bus bar layer and upper electrode layer are electrically connected together through the insulation layer.

摘要： An improved facsimile machine having at least one edge emitting thin film electroluminescent line array, each array having a plurality of pixels wherein the pixels are selectively activated. A light beam from each pixel is directed to a known point along a line on a document and reflects to a sensor. The reflected beam corresponds to a grey level at the point of reflection on the document and causes the sensor to generate a signal corresponding to that greyness level. Sufficient pixels are provided to generate sufficient light beams to strike all points along a line across a document.
