Abstract: An internal combustion engine controller includes a main processor for monitoring operating parameters of an internal combustion engine and a triggering device, working together with the main processor, for an electric fuel pump of the internal combustion engine. The triggering device works together with an electric activation device and operates so that the fuel pump is triggered essentially without time delay after actuation of the activation device. The internal combustion engine controller has an electronic switching device which operates so that, during an initialization process of the main processor, it triggers the electric fuel pump independently of the main processor.

Abstract: An internal combustion engine controller (120) includes a main processor (200) for monitoring operating parameters of an internal combustion engine (100) and a triggering device (170), working together with the main processor (200), for an electric fuel pump (110) of the internal combustion engine (100). The triggering device (170) works together with an electric activation device (205) and is designed in such a way that the fuel pump (110) is triggered essentially without time delay after actuation of the activation device (205). The internal combustion engine controller (120) has an electronic switching device which is designed so that, during an initialization process of the main processor (200), it triggers the electric fuel pump (110) independently of the main processor (200).

Abstract: A method of diagnosing an electric consumer using an analyzer unit is described. The electric consumer is supplied with a power supply voltage via a voltage divider. A first digital diagnostic port and a second diagnostic port of the analyzer unit are connected to the power supply voltage via the voltage divider. The diagnostic ports each detect a voltage Ulow or a voltage Uhigh, depending on the voltage applied.

Abstract: Through operation of a driving crank, the knotting apparatus is advanced over the canvas holder, on the one hand, and the various tools for the knotting operation are actuated, on the other hand. By means of drawing tongs (95) comprising two gripping arms (74, 92) the yarn (94) is pulled into the region of a needle head (103). With the front ends of two snaring arms (78,79) a cut-off piece of yarn is hung over the needle head (103). By means of two cross-arms guided parallel to the needle head, the ends of the piece of yarn are led through an aperture in the needle pushed through the canvas, whereupon the needle is retracted in order to form the knot. The desired color can be selected by means of a color selector (14). The method and apparatus make it possible to knot yarn (94) of selectively different colors rapidly and uniformly to the canvas.
