Appeal No. 95-4350
Application No. 08/212,082
frequency signals generated as a result of deformation of
structural members of the vehicle during the crash event, and an
analyzing means for combining and analyzing the signals from the
two sensing circuits so as to provide an indication of whether to
activate a passenger restraint device.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A sensing device for use in a passenger restraint system
that restrains a passenger within a vehicle during a crash event,
said sensing device comprising:
a low frequency sensing circuit providing a signal of the
crash event, said low frequency sensing circuit being responsive
to low frequency signals generated as a result of deceleration of
the vehicle during the crash event;
a high frequency sensing circuit providing a signal of the
crash event, said high frequency sensing circuit being responsive
to high frequency signals generated as a result of deformation of
structural members of the vehicle during the crash event;
analyzing means for combining and analyzing the signal from
the low frequency sensing circuit and the signal from the high
frequency sensing circuit so as to provide an indication of
whether to activate a passenger restraint device.
The references relied on by the examiner are:

Claims 1 through 4, 6 through 12, 14 through 16, 18 and 19
stand rejected under 35 U.S.C. § 103 as being unpatentable over
Diller in view of Feldmaier.
