摘要： The invention relates to a method for performing a contrast vision test on a subject in order to determine a contrast sensitivity function. According to said method, an image of a continuous sinusoidal grid is presented to the subject for viewing, the spatial frequency continuously changes in the direction of a first axis, and the contrast continuously changes in the direction of a second axis that extends perpendicular to the first axis. The subject's contrast sensitivity function is defined by means of a curve that encloses an area of the sinusoidal grid in which the subject perceives the sinusoidal grid pattern during viewing.

摘要： A diagonal fan has a diagonal fan impeller (1) which is fastened to a rotor (2) of an external rotor motor (3) and which is arranged between a front plate (5), which has an in particular central inflow opening (6), and a motor bracket (4). The motor bracket (4) is connected to the front plate (5) via a plurality of peripherally arranged spacers (21). Here, the front plate (5) and the motor bracket (4) are formed as plastic or metal injection molded parts. The spacers (21) are formed, as plastic or metal injection parts, in one piece with the front plate (5) or with the motor bracket (4).
