DRÄGER SAFETY AG & CO. KGAA Patent applications
Patent application numberTitlePublished
20110297828THERMAL IMAGING CAMERA - A thermal imaging camera is provided with at least two different sensitivities for alternating reading and with has a device for linking at least two more and less sensitive images read consecutively. The recording and displaying of thermal images makes it possible to combine images with two different dynamic ranges in a common thermal image, wherein the noise and drift of the pixel signals as well as the amount of storage needed for buffering and processing are reduced at the same time. An image buffering unit is designed as a common accumulator (12-08-2011
20110209712GAS MASK - A gas mask is provided for normal-pressure and overpressure operation with at least one breathing port, an expiration valve with a valve spring, an adjusting element affecting the prestress of the valve spring and a pushing element having a first switching position and a second switching position. The pushing element is designed to act on the adjusting element during a translatory motion from the first switching position into the second switching position. A change in the prestress of the valve spring can be brought about and a switchover from a “normal pressure” mode into an “overpressure” mode can thus be carried out.09-01-2011
20110139633PROCESS FOR VERIFYING AN ELECTROCHEMICAL SUBSTANCE IN A GAS SAMPLE - A process is provided for verifying an electrochemical substance in a gas sample. The process generates in an electrochemical sensor a measured electric value changing over time with a characteristic rising from a reference line to a maximum and again declining to the reference line. The percentage of the electrochemical substance in the gas sample is determined in an analysis circuit by setting a first interval and a second interval in the range of the characteristic after the maximum has been exceeded. The first interval includes the range of the characteristic in the vicinity of the maximum and the second interval includes the range of the maximum in the vicinity of the reference line. The electrochemical substance is determined by determining the ratio of the slopes of the first and second intervals and by comparison with a reference value of the ratio of the slopes of the first and second intervals.06-16-2011
20110094880: EXPLOSION-PROOF SENSOR - An explosion-proof sensor for detecting combustible gases is provided with a glass seal (04-28-2011
20110088454DEVICE FOR SELECTIVELY DETERMINING THE QUANTITY OF OIL MIST OR AEROSOLS - A measuring sensor (04-21-2011
20110048107DEVICE FOR GAS ANALYSIS - A device for gas analysis includes a detector tube (03-03-2011
20110031402INFRARED OPTICAL GAS-MEASURING DEVICE - A first, upper slotted disk (02-10-2011
20100275922SORPTION AGENT COMPRISING AN ACTIVATED CARBON IMPREGNATED WITH A ZINC COMPOUND AND A MOLYBDENUM COMPOUND AND GAS-FILTERING ELEMENT CONTAINING THE SORPTION AGENT - A sorption agent comprising activated carbon and an impregnation of the activated carbon for the sorption of air pollutants, wherein the impregnation contains a zinc compound and a molybdenum compound, as well as a gas-filtering element, such as a respirator canister, containing said sorption agent.11-04-2010
20100251804DEVICE AND PROCESS FOR RECOGNIZING A CORRECT USE OF AN ALCOHOL MEASURING DEVICE - A device and a process are provided for recognizing a correct use of an alcohol measuring device by a test subject. At least one alcohol measuring device is provided with a signal transmitter, an analysis and control unit and a camera unit. An image field of the camera unit is divided into an inner image field area and an outer image field area. The inner image field area detects at least the face area of the test subject. The camera unit records changes at a boundary between the inner image field area and the outer image field area. A signal sent by the signal transmitter in the inner image field area can be detected by the camera unit.10-07-2010
20100207024THERMAL IMAGING CAMERA - A thermal imaging camera (08-19-2010
20100192675EXPLOSION-PROOF GAS SENSOR WITHOUT PRESSURE-PROOF HOUSING - A gas sensor is provided for use in a hazardous explosive atmosphere present continuously or for a long time. The gas sensor is not provided with a pressure-proof housing and is provided with at least one catalytic or semiconductor measuring element (08-05-2010
20090322546SAFETY HELMET WITH GAS-MEASURING DEVICE - A safety helmet provides toxic gas monitoring in the field of vision of the helmet user. The safety helmet includes a gas-measuring device of modular design. The safety helmet has a sensor module (12-31-2009
20080237329PACKAGING FOR DETECTOR TUBES - A detector tube packaging is provided for packaging detector tubes with tips. The packaging includes a pushing insert for receiving a plurality of detector tubes located next to one another and a container for receiving the pushing insert via a first side of the container. A seal element may connect the pushing insert to the container. The seal may be broken to remove the insert and may be applied adjacent to or at a first side of the container. A detector tube opener is provided at another side of the container. The detector tube opener has openings corresponding to the number and the spacing of the detector tubes. The openings are located next to each other with each opening having an opening diameter substantially corresponding to a diameter of the tips of the detector tubes.10-02-2008
