AM provides substantially longer recep-
tion ranges than FM. AM broadcast sig-
nals, propagated at ground level in the
form of surface waves, are also reßected
from the ionosphere as atmospheric
waves.
Frequency-modulation (FM) provides
substantially better sound quality than
AM. However, because FM transmis-
sions rely on line-of-sight broadcast
waves, their effective reception range is
limited. Although numerous factors combine to
impose inherent limitations on the
reception quality available from mobile
radios, specially designed systems can
be employed to minimize their effects:
The Antenna Diversity system employs
several FM antennas integrated within
the rear window to provide three sepa-
rate sources for receiving broadcast
waves. An integral processor automati-
cally selects the antenna with the best
FM reception quality at any given time.
Because the ongoing antenna selection
process is completed within millisec-
onds, it remains inaudible to the radio
listener. The safety belt tensioner responds to
collisions by tightening the belts to
ensure that occupants remain firmly
positioned in their seats. A gas-pres-
sure system retracts the buckle assem-
bly to tension the shoulder and lap belts
within fractions of a second, preventing
the driver and passenger from slipping
forward.360de084
