摘要:
A method for winding a stator for a brushless direct current motor, which has a stator body (9) with a predetermined number of to be wound stator teeth (3) with the stator teeth (3) respectively being wound with two coils (W1, W3; W2, W4) which are magnetically coupled and which facilitate by supply of current with variable directional orientation the generation of opposite magnetic fields, whereby each of the two coils (W1, W3, W2, W4) comprises a predetermined number of in parallel arranged conductors. The stator teeth (3) are respectively wound simultaneously in several partial winding steps, with two conductors (25, 27) or with an even number of 2n conductors, whereby one of the two conductors (25, 27) or n conductor of the 2n conductors is allocated to the one coil and the other of the two conductors (25, 27) or the other n conductor of the 2n conductors are allocated to the other coil and whereby a pre-determined number of partial winding steps is performed until the pre-determined number of conductors per coil (W1, W3; W2, W4) has been reached.

The device comprises an input unit for the automated mechanical actuation of the at least one input element of the device, an image analysis unit, which acquires and analyzes the visual output of the device, and a control unit, which controls the input unit and image analysis unit, and automatically determines a test result based on predetermined desired outputs and the findings of the image analysis unit.
摘要:
A system and process for monitoring the valves of an anesthetic dispenser with a safety valve (2) and with a dispensing valve (3) for dispensing the anesthetic in the form of a vapor. The valves are connected in series. A system has a downstream dispensing gap (5) and a fixed bypass resistance (9). The dispensing valve (3) is first opened for an equalization time. The safety valve (2) and the dispensing valve (3) are closed and the differential pressure between the saturated vapor branch (4) and the mixed gas branch (8) is measured by means of a differential pressure sensor (6, 7). The safety valve (2) or the dispensing valve (3) is opened and the differential pressure between the saturated vapor branch (4) and the mixed gas branch (8) is measured by means of the differential pressure sensor (6, 7). The opened safety valve (2) or the opened dispensing valve (3) is closed and the difference between the differential pressures measured are determined and compared with a preset limit value, so that the valve (2, 3) that is not opened is considered to be tight when the difference is below this limit value.
摘要:
An optical measurement device for measurement of chemical and/or biological samples comprises an illumination means (16) for illuminating the sample (20) to be measured. Further, an optics means (22) is provided for imaging a sample area in an image field (10). A first partial area (12) of the image field is covered by a first detector (28), and a second partial area (14) of the image field (10) is covered by a second detector (34). Thus, it is possible to change between two measurement methods without switching or to perform two measurements on a sample at the same time.

A device for measuring the optical properties of an object, particularly of a chemical and/or biological sample, comprises an illumination light source for illuminating the object. Further, an excitation light source is provided for illuminating the object, wherein the radiation of the excitation light source being suited to change the optical properties of the object. Further, the excitation radiation is focused in a measurement volume arranged within the object. By means of a detector device, there can be detected preferably the transmission of the illumination radiation through the object within the measurement volume.

The method for determining the mass of a vehicle comprises at least two measurements (6, 8) offset in time within a measuring period by which are determined respectively at least one traction variable (2) and at least one movement variable (4) of the vehicle, one of the two measurements (8) being effected during a traction-free phase and the other of the two measurements (6) during a traction phase. According to the invention, it is proposed that each of the two measurements comprises one data collection period (6, 8) the duration of which is longer than a minimum duration, that the traction variable corresponds to the timed integral of the traction and the movement variable to the change of speed of the vehicle.
