  • Patent number: 8366303
    Abstract: The present invention provides an automotive interior lamp assembly mounted to an automotive headliner further including a curtain side airbag mounted about the headliner. As the curtain side airbag quickly deploys and forces through the vehicle headliner, the lamp assembly can be forcibly detached from the headliner at a high rate of speed. The present invention provides an improved retainer to better attach the light assembly to the headliner thereby preventing detachment of the lamp assembly from the headliner. The lamp assembly includes a lamp housing having a lamp receiving configured to accept a lamp. The housing further includes a retainer receiving side configured to accept a retainer. The retainer attached to the housing by means of a plurality of attachment members provided on the retainer, and at least one snap member also provided on the retainer. The housing has a plurality of attachment member receiving cavities and at least one snap member receiving cavity.

  • Patent number: 8240750
    Abstract: An air duct system which mates an air duct attached to the roof of an automotive vehicle and an air duct attached to a nonexposed surface of a headliner is provided. The air duct system is attached to an air supply which delivers directed air and is disposed between an inner surface of the roof and the nonexposed surface of the headliner. The headliner includes an opening into the passenger compartment of the automotive vehicle. The air duct system includes a first air duct and a second air duct. The first air duct is attached to the inner surface of the roof, and the second air duct is attached to the nonexposed surface of the headliner. Upon installation of the headliner to the roof a portal on the first air duct registers with a portal on the second air duct so as to provide an air flow passage between said first air duct and said second air duct.

  • Patent number: 8180309
    Abstract: A lock-in amplifier with an additional phase-sensitive detector is provided. A measurement signal is mixed in a multiplicative fashion with a reference signal, which is phase-shifted by 90 degrees, for a modulation frequency. In order to reliably filter out interference signal portions in a widest possible dynamic range and, at the same time, minimize unavoidable influence on the useful signal portion, a control device is connected downstream of the additional phase-sensitive detector. The control device determines a control variable corresponding to the strength of the interference signal from the measurement signal mixed with the reference signal phase shifted by 90 degrees and uses the control variable to change the integration duration of the integrator proportionally to the control variable, a corresponding cut-off frequency of an equivalent low pass being coordinated automatically.
