Abstract: A system and method for rendering a virtual sound source using a plurality of speakers in an arbitrary arrangement includes expanding a wave field of the virtual sound source and a composite wave field generated by the plurality of speakers into multi-pole expansions, and equating the multi-pole expansions to each other to form a continuous equation. A set of constraints is applied to the continuous equation that minimize an error in a sweet spot region resulting in a linear system of equations. The linear system of equations is solved using singular-value decomposition to arrive at a pseudo-inverse representing a multi-dimensional transfer function between the virtual sound source and the plurality of speakers. The multi-dimensional transfer function is then applied to a signal of the virtual sound source to render the virtual sound source in the sweet spot region using the plurality of speakers in the arbitrary arrangement.

Abstract: The invention relates to an instrument panel for a motor vehicle comprising a firing channel for an inflating airbag, with the firing channel simultaneously forming an airbag housing in which the airbag is accommodated in the folded state, and with a gas generator for the inflation of the airbag being attached to the airbag housing separately from the airbag and in a gas-tight manner. The invention furthermore relates to a method for the installation of an airbag module to a motor vehicle instrument panel.

Abstract: The invention relates to an airbag module for motor vehicles comprising a housing for an inflatable airbag and a gas generator which is connected to a base element fixed to the module in the assembled state, with the gas generator and the base element being combined to form an assembly serving as a vibration absorber and being unreleasably connected to one another by at least one elastic and/or vibration damping coupling element via which the gas generator is supported over its area at the base element.

Abstract: An apparatus and method for the multiple detection of optoelectronic signals, especially for detecting the positions of setting elements of flaps, slides, valves, etc. arranged in motor vehicles, to determine the steering angles for controlling driving dynamics, or to determine rotational angles or a linear movement converted into a rotational movement. At least two signal paths extend at an angle relative to one another, with one signal path extending substantially parallel to and under a clock disc and with the second signal path intersecting a sensor element perpendicularly through the clock disc. Signals in the first signal path are deflected by a reflector element underneath the clock disc in the direction towards the sensor element where the coincide with signals in the second signal path.

Abstract: In the case of an encoder with a housing, which can be assembled, for flanging at the front end to a motor, which has a motor shaft protruding into the housing at at least one flange plane, the housing consists of a base plate with an inner part and an upper part of the housing, which can be fitted into one another for the assembly. On the inner part of the housing, bayonet segments are disposed, which engage corresponding recesses of the upper part of the housing and at which guiding surfaces are constructed, which form a sliding guide with corresponding counter surfaces at the upper part of the housing. In a roof surface of the upper part of the housing, a contact surface for adjusting a timing disk on the motor shaft is formed concentrically with the latter, which has a guiding shaft for the motor shaft with a borehole.

Abstract: A air bag module comprises an inflator, a unitary polymeric housing, and an air bag retainer of the same or similar material. The housing has integral walls forming an inflator chamber which include an inflator mounting stud aperture, a plurality of integral supports for the inflator, an integral peripheral rim forming an airbag chamber, and an integral upper wall having inflator gas diffuser apertures. An inflator stud fastener secures the inflator to the housing. The retainer and housing have integral cooperating fasteners for securing the retainer to the housing. A polymeric cover closes the retainer and confines the attached air bag. The housing and retainer are formed of the same recyclable material such that the air bag assembly can be recycled by simply removing only the stud fastener and the inflator. Several embodiments of the housing, retainer and fasteners are disclosed. In one embodiment, an inflator gas diffuser that is integral with the housing.

Abstract: A steering wheel angle sensor includes first and second sensors, a differential gear, and a detector. The first sensor determines steering wheel angular position within one revolution and the second sensor determines number of steering wheel revolutions. The first sensor has a first rotor carrying a first coding. The first rotor and the first coding rotate as the steering wheel rotates. The second sensor has a second rotor and a second coding movable by the second rotor. The gear includes driving, reference, and planetary wheels for coupling the rotors such that the rotors rotate at different speeds with respect to one another as the steering wheel rotates. The second rotor engages with a pivoted lever into an arm carrying the second coding such that the second coding pivots as the second rotor rotates. The detector scans the first coding within an angular segment of the steering wheel range of rotation as the first coding rotates.

Abstract: A housing (10) is provided for a folded together inflatable airbag and a holder element (12) which can be locked at the housing, with the housing and the holder element bounding a reception region for a gas generator (14) in the locked state. In addition to an airbag and a gas generator, with the housing and the holder element, only two components are required in accordance with the invention, through which the manufacture may be simplified and manufacturing cost reductions may occur. For the assembly of the airbag module, the gas generator (14) is first arranged either at the housing (10) or at the holder element (12) and then the holder element is locked at the housing. The gas generator (14) is then already located in its final position in the airbag module. Through this the subsequent attachment of the folded together airbag in the housing is simplified since more than two parts which are to be connected together need never be brought into the correct relative position.

Abstract: An airbag module for motor vehicles includes a housing for a folded together inflatable airbag and a holder element that can be locked at the housing. The holder element has at least one locking section, which in the locked state extends along the housing wall and latches with a holder section of the housing at its side which faces away from the housing wall.
