摘要: A beam detection apparatus for sensing the position of an electron beam within a cathode ray tube is disclosed. The apparatus includes a photodetector for optically detecting the intersections of the electron beam with a graticule line on the faceplate of the cathode ray tube. In a second embodiment, an electrically conductive pattern of reference markers is applied to the graticule for intercepting the beam and a detector is coupled to the conductive pattern for detecting the interception. Calibration circuitry is also included to generate input signals to deflection amplifiers coupled to the cathode ray tube and to evaluate detection signals generated by the beam coinciding with a graticule line. The calibration circuitry compares the input signals to the input signal value represented by the graticule line and adjusts the deflection amplifiers of the cathode ray tube accordingly to cause the beam to coincide with a graticule line bearing a predetermined relationship to the input signal deflecting the beam.

摘要: A signal processing system employing charge transfer devices for fast-in slow-out operation is disclosed. A push-pull input analog signal is applied to two charge transfer devices, and the clock pulses applied thereto are shifted one-half clock cycle with respect to one another. The output signals from the two charge transfer devices are differentially summed, and thereby providing cancellation of dark current and clock related noise in the charge transfer device, and doubled sample rate.

摘要: An ophthalmic lens of photochromic glass having an R.sub.2 O-Al.sub.2 O.sub.3 -B.sub.2 O.sub.3 -SiO.sub.2 base glass composition and a method of producing the lens. The lens contains precipitated cuprous halide crystals that are elongated and oriented, whereby the lens is capable of polarizing light when the lens is in the darkened state. If at least a portion of the crystals in at least a surface layer on the lens are reduced to copper metal, the lens exhibits a permanent dichroic behavior. The lens provides effective polarization of radiation across the entire visible wavelength region of the spectrum, has a sharp spectral cutoff for radiation below the 400 nm wavelength, thereby eliminating UV transmission, and has a transmittance not over about 40% in the darkened state.
