  • Patent number: 11929084
    Abstract: An audio encoder for encoding an audio signal has: a first encoding processor for encoding a first audio signal portion in a frequency domain, having: a time frequency converter for converting the first audio signal portion into a frequency domain representation; an analyzer for analyzing the frequency domain representation to determine first spectral portions to be encoded with a first spectral resolution and second regions to be encoded with a second resolution; and a spectral encoder for encoding the first spectral portions with the first spectral resolution and encoding the second portions with the second resolution; a second encoding processor for encoding a second different audio signal portion in the time domain; a controller for analyzing and determining, which portion of the audio signal is the first audio signal portion encoded in the frequency domain and which portion is the second audio signal portion encoded in the time domain; and an encoded signal former for forming an encoded audio signal havi

  • Patent number: 11915712
    Abstract: An audio encoder for encoding an audio signal includes: a first encoding processor for encoding a first audio signal portion in a frequency domain, wherein the first encoding processor includes: a time frequency converter for converting the first audio signal portion into a frequency domain representation having spectral lines up to a maximum frequency of the first audio signal portion; a spectral encoder for encoding the frequency domain representation; a second encoding processor for encoding a second different audio signal portion in the time domain; a cross-processor for calculating, from the encoded spectral representation of the first audio signal portion, initialization data of the second encoding processor, so that the second encoding processing is initialized to encode the second audio signal portion immediately following the first audio signal portion in time in the audio signal; a controller configured for analyzing the audio signal and for determining, which portion of the audio signal is the firs

  • Patent number: 8140221
    Abstract: A motor vehicle has a vehicle body and a chassis that has at least one wheel suspension device for two opposing wheel. An adjusting device is assigned to each of the wheels. The adjusting devices are coupled to one another by a stabilizer. At least two stabilizer bearings are provided for rotatable support of the stabilizer, and at least one coupling device is provided on the vehicle body for variable torque support of the stabilizer. Accordingly, a reliable level lifting function is provided, based on a sturdy configuration that is both space-saving and weight-saving. The coupling device for torque support of the stabilizer on the vehicle body may have a switchable blocking device and/or at least one spring mechanism.

  • Patent number: 8029002
    Abstract: An inner and an outer spring plate are disposed, in a radially spaced relationship from one another, on a spring strut cylinder. In a first springing position (normal position), the helical spring is supported with a turn region of small diameter against the inner spring plate. In a second springing position (sports position) of the helical spring, the latter is supported with a turn region of larger diameter against the outer spring plate.

  • Patent number: 5499839
    Abstract: A wheel suspension for an axle of a motor vehicle has a transverse control arm and tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of lateral and peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged below a wheel drive shaft and--with respect to the driving direction--in front of a tie rod. In the top view, the tension strut extends diagonally toward the front, the transverse control arm and the tie rod having a positive position with respect to one another. They form a wheel steering pole situated outside the track width and behind the wheel center transverse plane.

  • Patent number: 5498018
    Abstract: A wheel suspension for an axle of a motor vehicle, particularly a McPherson front axle, has a transverse control arm and a pivotally connected tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged in an approximately horizontal plane and extends below the wheel spin axis approximately in a wheel center transverse plane. The tension strut is pivotally connected to the transverse control arm by way of a connection bearing and extends at an angle diagonally with respect to a longitudinal center axis of the vehicle.

  • Patent number: 4872372
    Abstract: For improving the load-change behavior of a motor vehicle when driving through a curve, the motor vehicle is provided with a lockable differential continuously activatable in its locking action. The activation of the locking differential takes place in the first instance in two steps dependent on power output, whereby a velocity-dependent characteristic may be superimposed additionally on this power output-dependent control.

  • Patent number: 4754835
    Abstract: A control arrangement for a four-wheel drive vehicle which has at least one gear box or differential with controllable power transmission characteristics having circuitry for producing control signals in response to vehicle operating conditions and parameters. The arrangement allows for control of the distribution of torque to the respective wheels of the vehicle as a function of a selected number of parameters, such as relative or average wheel speed, engine speed, gas pedal or throttle valve angle, etc. The arrangement contemplates the simultaneous control of more than one adjustable gear box or differential as a function of commonly and/or separately sensed parameters.
