Abstract: The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device connected to the detector arrangement. The filter arrangement has at least a first filter, the suspect filter, and at least one second filter, the reference filter(s). The first filter is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band. The at least one second filter is configured as a band pass filter allowing the passage of a second predetermined band(s), the reference band(s). The detector arrangement has at least one detector associated with at least one of the filters. The band passes reference filters are distributed above and below the band pass of the suspect filter. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO2.

Abstract: An IR sensor (1), especially a CO2 sensor, is described, having a filter arrangement (6), downstream of which there is arranged a detector arrangement (7), and an evaluating device (8) which is connected to the detector arrangement (7), the filter arrangement (6) having a first filter (9) and a second filter (10), which are configured as bandpass filters and each have a passband and of which the first filter (9) allows passage of a predetermined IR band and the second filter (10) does not, and the detector arrangement having two detectors (14, 15), each of which is associated with a filter (9, 10). The objective is to simplify the use of such an IR sensor. For that purpose, the passband of one filter (10) is arranged within the passband of the other filter (9) and the evaluating device (8) forms the difference of the signals (S1, S2) of the detectors (14, 15) and normalises it to the signal (S1) of a detector (14).

Abstract: In a motor actuator, e.g., a valve actuator, comprising a reversible electrical motor, a drive circuit is providing a stop function, when the torque of the motor exceeds a predetermined maximum torque. The drive circuit is constructed as a two-terminal circuit connected in series with the reversible electrical motor, and the electrical power is supplied to the series connection with a mainly fixed voltage VCC and a polarity which provides the desired rotational direction of the motor. This provides the possibility of having the drive circuit positioned close to the motor and maintaining full torque control and stop function with two wire connections.

Abstract: The present invention relates to a medication delivery device comprising a cartridge assembly, a dosing assembly and optionally a needle assembly. The cartridge assembly comprises a cartridge having a stopper adapted to receive a plunger. Furthermore, the cartridge assembly has one end sealed with a pierce able sealing, said end comprising coupling device for engaging a needle assembly, and another end comprising coupling device for engaging the dosing assembly. The dosing assembly comprises a plunger and has coupling device for engaging the cartridge assembly. The cartridge assembly and the dosing assembly are coupled together for delivering selected doses of medication. The device further comprises mechanism for securing that the plunger abuts on the stopper during use of the device, in particular when the dosing assembly is releasable coupled to the cartridge assembly.

Abstract: By a cylinder ampoule (1), comprising a tubular vessel with a membrane (4) sealingly closing one end and a piston (9) closing the other end, liquid stored between said piston (9) and said membrane (4) can be pressed out through an injection needle (7) piercing the membrane (4) when the piston (9) is pressed into the ampoule (1). The tube is made from a plastically deformable material. A pressure foot (10) on which a piston rod (13) is acting abuts the piston (9), carries a spring plate (11) made from a harder material than is the ampoule (1), is mainly perpendicular to the ampoule (1) axis, and has at least one diameter which is larger than the inner diameter of the ampoule (1) so that edges of the plate (11) abutting the inner wall of the ampoule (1) are deflected away from the piston (9) to form an acute angle with said wall.
