A method is proposed for assembling micromechanical sensors, in particular Hall sensors, or pressure or acceleration sensors, in which at least one silicon sensor element is applied to a substrate. The at least one silicon sensor element is joined to the substrate via at least one assembly pedestal, the cap faces of which are kept small compared with the surface of the silicon sensor element, so that a gap exists between the substrate and the silicon sensor element except for the region of the at least one assembly pedestal.

Method of assembling micromechanical sensors

A frequency divider circuit and variants thereof, intended for use with the fuel injection system of an internal combustion engine. The primary trigger signal is one derived from a rotating engine member and this signal is used to generate two input pulse trains of opposite relative phase. A basic dividing block includes two bistable multivibrators formed by gates with crossed feedback. The inputs to these multivibrators are provided by two-input gates and the input pulse trains are applied, respectively, to the input gates ahead of the first and second multivibrators. The second inputs of the input gates receive the direct or crossed-over outputs of the multivibrators. Additional circuitry is disclosed for providing odd dividing ratios, e.g. 1:3.
