| Number | Title | Issue Date |
| 4249168 | Flame detector The detector has first and second circuits which are interconnected. The first circuit senses the emission of a flame at least in the wavelength range of carbon dioxide and produces square-wave signals corresponding to the flicker frequency. The second ci... | 02/03/1981 |
| 4247848 | Fire detector with a monitor circuit In response to oscillator output pulses, a sample pulse generator supplies sample pulses to a fire sensor. In response to the sample pulses, the fire sensor produces a fire sensor signal. A judging circuit receives the fire sensor signals and, if they exc... | 01/27/1981 |
| 4195286 | Alarm system having improved false alarm rate and detection reliability An alarm system has two output modes, one providing relatively high detection probability and the other providing relatively low false alarm probability. Two or more sensors are coupled to an associated logic circuit which provides a first alarm output in... | 03/25/1980 |
| 4151522 | Count discriminating fire detection system A fire detector senses the change in a physical parameter indicative of a fire such as smoke, heat or the like and produces detection pulses in synchronism with an oscillator circuit when the change in the physical parameter exceeds a predetermined amount... | 04/24/1979 |
| 4149159 | Fire detection system In a fire detection system, detectors of different sensitivities are arranged in pairs and the pairs of fire detectors are positioned at regular intervals along an elongated protection area, whereby detectors of one sensitivity alternating with detectors ... | 04/10/1979 |
| 3999079 | Fire detector The fire detector in which only an increasing component of the voltage produced by a transducer is applied to a timing-circuit and a voltage detected by said transducer is converted in waveform into sawtooth wave form which increases in accordance with th... | 12/21/1976 |
