Abstract: A piston compressor includes a crankcase (11), a crankshaft (12), connecting rods (13), a crosshead (14) with an arranged piston rod (15) and a piston (16), dry-running guided in a cylinder (17). Valves (18) are provided. A piston rod sealing device (19), around the piston rod between the cylinder (17) and the crankcase, includes a gland device (22), arranged in a gland housing (21), inserted into a piston compressor housing (20). The gland device includes a gland jacket (24) pushed into a gland (23) limiting, with the piston rod, a sealing gap (25), which is open over a common longitudinal section, has a width in the μm range and allows a leakage flow (26) of the compressed medium therethrough. The gland and the gland jacket are formed of different materials with a resulting coefficient of thermal expansion essentially the same as the material of the piston rod.

Abstract: An HME device, used in a closed breathing circuit of a ventilation system, has a housing with an inlet opening and with an outlet opening, an HME chamber (50a; 50b; 50c; 50d; 50e; 50f; 50g; 50h; 50i) arranged between the inlet opening and the outlet opening for receiving an HME medium and a switching mechanism (70a; 70b; 70c; 70d; 70e; 70f; 70g; 70h; 70i). The HME device can be switched over between an HME mode (M1), in which an HME fluid passage is provided from the inlet opening through the HME chamber to the outlet opening, and a bypass mode (M2), in which a fluid bypass passage is provided from the inlet opening past the HME chamber through a bypass channel (80a; 80b; 80d; 80e; 80f; 80h) in the housing to the outlet opening. The bypass channel is blocked with respect to the HME chamber in the bypass mode (M2).

Abstract: A process for analyzing multidimensional vector data of a motion sensor for detecting a breathing motion, includes receiving and storing the multidimensional vector data of the motion sensor in a time series, calculating a plurality of medium-term vectors and of a plurality of long-term average vectors, calculating and storing a plurality of mean-free vectors depending on a difference between a respective medium-term vector and a respective long-term average vector and determining a plurality of unit vectors. The respective unit vector is oriented in a random direction. A plurality of scalar products are calculated from a respective mean-free vector and the unit vector assigned to the mean-free vector. A motion identification is calculated, which is an indicator of the breathing motion, based on the plurality of scalar products. An analysis signal is determined and output based on a comparison between the motion identification and a predefined motion threshold value.

Abstract: The device comprises at least a laser source (5); an optical fiber (1) with an optical radiation entrance end (1.2) and an optical radiation output end (1.1); and a coupling system (8) for coupling the laser source (5) and the optical fiber (1), adapted to inject an optical radiation emitted by the laser source (5) into the entrance end (1.2) of the optical fiber (1). The optical fiber (1) is a multi-mode optical fiber. The coupling system (8) is adapted to inject the optical radiation into the optical fiber (1) with such an inclination (a) as to reduce or eliminate the fundamental transmission mode and to promote the transmission according to at least one higher-order transmission mode The optical radiation at the output end (1.1) of the optical fiber (1) has a cone-shaped distribution (3) wherein the intensity is maximal on the peripheral volume of an emission cone and is minimal inside the emission cone.

Abstract: A gas detection device and a process monitor an area for a combustible target gas. A heating segment of a detector (10) is heated when electrical current flows therethrough. A heating segment of a compensator (1) is heated when electrical current flows therethrough. An electrical voltage is applied to both the detector and the compensator. The heating of the detector (10) causes a combustible target gas to be oxidized in an interior of the gas detection device. A detection variable, which depends on the temperature (Temp_10) of the detector, and a detection variable, which depends on the temperature (Temp_11) of the compensator, are measured. A presence and/or a concentration of a target gas are determined as a function of the detection variables. A quality parameter is measured and increases as the detection variable depending on the detector temperature increases and as the detection variable depending on the compensator temperature decreases.
