The invention relates to a sensor arrangement for seat occupation detection, comprising a fiber-optic sensor network consisting of at least two sensors. The sensor network detest for example local damping modifications in a fiber network that are caused by microbends or modifications of the Bragg wavelength of fiber-optic Bragg grating sensors (FBGS) distributed in the fiber network that are ceased by loads. The optical sensor network is resistant to electromagnetic parasitic inductions. Due to the nature of the optical lass or polymer optical fibers it is for example possible to integrate the network into the textile cover of the seat or into a cushion.

In a method for controlling a safety system in a vehicle, wherein an output signal of at least one impact sensor is subjected to frequency analysis in an evaluation unit which is integrated into an electronic control unit, the frequency analysis is performed in at least one predetermined frequency range, the spectrum of the output signal is compared with references patterns, the dependence of the spectrum on the present speed of the vehicle and/or the present outside temperature of the vehicle is taken into account, and a triggering signal is generated from the control unit to trigger planned protective measures if a person to be protected is detected with at least a predetermined probability.

摘要:
A pyrotechnical ignition system with integrated ignition circuit for an occupant restraint system for motor vehicles includes electrical components for triggering or communication functions integrated therein, a capacitor arrangement, having a flat non-conductive external surface is used as a substrate or carrier element on which the other components are directly arranged and carried. A conductor structure linking the components can be formed by insertable metal parts that are arranged in the housing and project into the holding chamber in which the capacitor arrangement and the circuit component are arranged, and make contact with contact zones on the upper side of the circuit or the capacitor arrangement. The conductor structure may be a printed-conductor structure that is precipitated on non-conductive external surfaces of the capacitor arrangement, and the lateral surfaces thereof, connect the upper and the lower sides of the ignition capacitor as well as the individual capacitor electrodes within the capacitor arrangement to form one or several capacitors, in particular the ignition capacitor. The ignition bridge layer is situated on the capacitor arrangement or on the circuit.

Fatty acid derivatives based on epoxidized unsaturated fatty acid esters or triglycerides and reacted with amines such as hydroxy- and/or amino-substituted hydrophilic amines or amino acids and/or with alkanols or with water on the epoxy group and/or the carboxylic ester groups are described. These fatty amides are suitable as surfactants in detergents and cleaners.

An arrangement of electronic components in a housing includes a housing, at least one circuit board arranged in the housing with electronic components of a first type (such as SMDs) mounted thereon, at least one electronic component of a second type (such as a non-SMD coil or capacitor) that is not arranged on the circuit board but rather is mounted on a mounting surface in the housing, and an electrical connection established between the second electronic component and the circuit board. The electrical connection may be established by a connector member having two connecting shanks connected to the wires of the second component and two mounting shanks that are press-fit into contact holes of the circuit board. Alternatively, the electrical connection may be established by respective contact clips electrically and mechanically clamped onto the wires of the second component, whereby the contact clips have contact pins that plug into contact holes in the circuit board.
摘要:
The invention relates to a device for sealing pressure compensation openings in components in particular of a motor vehicle control unit. Previously, pressure compensation openings were sealed in the interior of the housing by a watertight and gas-permeable material affixed by adhesion. In accordance with the invention, the opening is sealed from the outside with a two-layered material where a wide-area first layer consists of a material that can be inscribed and a second layer, which can also be provided over just a part of the total area, is a watertight and gas-permeable membrane. At those places where pressure compensation occurs, the first layer is removed so that only the membrane acts. The first layer can be used here as a label. Advantages offered by this device are that the housing and the membrane are joined over a much larger area, the process can be monitored, and one process step is saved.
