Abstract: A photo monitoring apparatus including a photoresistor, a series of shunt resistors, and a comparator IC, wherein the comparator IC provides an output signal to a LED and a diaphragm speaker, when the voltage from the shunt resistors drops below a pre-set reference voltage, causing the LED to give light and the diaphragm speaker to produce a warning sound. The shell of the photo monitoring apparatus is installed with a digital time display controlled by a time circuit to indicate time.

Abstract: System and method for analyzing pulses from an excimer laser by measuring light energy rather than heat energy. The output of the laser is monitored with a photodetector to provide electrical current pulses corresponding to the intensity of the light in individual ones of the laser pulses. The current pulses are integrated to provide voltages corresponding to the light energy of the laser pulses, and the voltages are converted to digital signals. The digital signals are accumulated during the exposure period to determine the total light energy of the pulses during that period and also during a shorter interval of time during the exposure period. The light energy for the interval is divided by the length of the interval to determine the average intensity of the pulses during the interval. Displays are provided for the light energy and the intensity of the pulses, as well as the length of the exposure period.

Abstract: A compact low-cost fire detector responds quickly by detecting an increase in the concentration of carbon dioxide gas in the ambient air. The detector also calculates the rate of build-up of carbon dioxide. The detector avoids the use of moving parts by employing a differential temperature black body source of infrared radiation in conjunction with a dual pass band filter. One of the pass bands is located at the 4.26 micron absorption band of carbon dioxide gas and the other pass band is located at 2.20 microns at which none of the atmospheric gases has an absorption band. The latter channel serves as a reference and renders the detector immune to false alarms caused by dust or smoke particles in the air or due to deterioration of certain components. The fire detector makes use of a sample chamber that consists of a serpentine passage in a block of material, the walls of the serpentine passsage being highly reflective so as to act as a light pipe.

Abstract: Described is herein a radiation measuring apparatus in which a detected pulse signal having a wave height value proportional to energy of radiation is transmitted through an optical fiber and a detected pulse signal received from the optical fiber is supplied to an external apparatus. Even if the transmission loss of the optical fiber is subjected to change with passage of time, a monitor pulse signal having a polarity reverse to that of a detected pulse signal is overlapped on the detected pulse signal lest the wave height of the detected pulse signal be not varied on the transmitting side, and a wave height value of a monitor pulse signal passed through the optical fiber is detected to compensate the wave height of the received detected pulse signal using the detected value.

Abstract: The concentration of optically active substances is determined by measuring the polarization of light passed through the substance using a light source, a polarizer and a modulator operated at a predetermined modulation frequency f.sub.F, as well as a measuring cell, an analyzer and a detector. The output signal from the detector 16 is alternately integrated during each half period of the modulation frequency to form voltage values U.sub.I+ and U.sub.I-. These voltage values are stored and the quotient Q of these stored voltage values is formed. Subsequently, an adjustable constant voltage is subtracted from the quotient. The measuring arrangement can have a miniature design for implantation. No mechanically moving parts and only a single detector are used. The measurement is accomplished by a simple, miniature linear ray path having high resolution.

Abstract: Gas analyzers of the non-dispersive infrared radiation type which are designed to measure the concentration of one gas in a mixture of gases containing that gas. A novel, electrically modulated, stable, thick film infrared radiation emitter is employed to emit a beam of collimated, focused energy; and two electrically biased detectors are preferably used so that a ratioed, error eliminating output signal can be supplied to the failsafe, signal processing circuitry of the analyzer. The latter, and a conventional analog-to-digital convertor, supply information to a microcomputer which: (1) turns the infrared radiation emitter on and off; (2) controls a heater which keeps the infrared radiation detectors at a constant, precise temperature; and (3) controls displays of a variety of information concerning the gas being measured and the status of the gas analyzer. The microcomputer also accepts ambient temperature, barometric pressure, and other compensation factors. Typically, a disposable airway adapter will be included in the gas analyzer to confine the mixture of gases being analyzed to a path having a transverse dimension of precise and specific length and to provide an optical path across that stream of gases between the infrared radiation emitter and the infrared radiation detectors. The emitter and detectors are incorporated in a transducer head which can be detachably fixed to the airway adapter.

Abstract: A flare monitoring apparatus for detecting the generation of black smoke in a flare, the excessiveness of a flare and extinguishment of a flare based on the ratio and/or difference between an emissive power of infrared radiation emitted from a flare at a wave length at which a peak of the emissive power due to a resonance infrared radiation of a specified gas contained in a flue gas exists and an emissive power of infrared radiation emitted from the flare at another wave length at which a peak of the emissive power due to a resonance radiation does not exist. The apparatus produces an alarm and automatically controls the state of the flare upon the detection of the abnormality of the flare.
