FOR IMMEDIATE RELEASE
Emergency Warning System for Vehicles
Abstract
A vehicular warning system is disclosed that transmits
information concerning a moving vehicle's rate of deceleration and
magnetic orientation to surrounding vehicles carrying the warning
system. Auditory and/or visual alerts are generated within
surrounding vehicles carrying the inventive warning system to warn
the driver therein of the rapidly decelerating vehicle ahead.
03/30/04 -- We claim:
1. A severe braking warning system comprising
a. an accelerometer programmed to measure deceleration forces
exerted on it by a moving first vehicle in which said system is
installed and to transmit varying output signals correlating to
said deceleration forces;
b. a microprocessor electrically connected to said accelerometer,
said microprocessor programmed to monitor said varying output
signals from said accelerometer;
c. a compass module electrically connected to said microprocessor
and configured to detect a magnetic orientation of said first
vehicle and transmit to said microprocessor an output signal
corresponding to said magnetic orientation;
d. a radio frequency transceiver electrically connected to said
microprocessor, said transceiver designed to transmit radio
frequency signals to a second transceiver of a second braking
warning system upon activation by said microprocessor, said
transmitted radio frequency signals corresponding to said
deceleration forces exerted on said first vehicle and
corresponding to said magnetic orientation of said first vehicle;
e. said radio frequency transceiver further designed to receive
radio frequency signals from a severe braking warning system
installed in a second vehicle, said received radio frequency
signals corresponding to a deceleration level and magnetic
orientation of said second vehicle;
f. an alerting device electrically connected to said
microprocessor, said alerting device is configured to convey
visual or auditory alerts within said first vehicle upon
activation by said microprocessor;
g. said microprocessor programmed to compare said received signals
from said transceiver to said first vehicle's magnetic orientation
to determine whether said second vehicle's orientation is within a
pre-programmed angular range with respect to said first vehicle's
orientation, whereby when said second vehicle is within said
angular range, said microprocessor is programmed to activate said
aural indicator to transmit said auditory alerts within said first
vehicle; and
h. said microprocessor is further programmed to ignore said
received signals from said transceiver when said first vehicle is
traveling at a deceleration rate corresponding to a pre-programmed
deceleration rate value.
2. The system of claim 1, wherein said first and second vehicles
are motorized vehicles.
3. The system of claim 2, wherein said motorized vehicles are
selected from the group of motorcycles, automobiles, three-wheel
all-terrain vehicles, buses, vans, motor homes, sport utility
vehicles, construction vehicles, trucks, and remote-controlled
vehicles.
4. A warning system comprising:
a. an accelerometer programmed to measure deceleration forces
exerted on it by a moving vehicle in which said system is
installed and to transmit varying output signals correlating to
said deceleration forces;
b. a microprocessor electrically connected to said accelerometer,
said microprocessor programmed to monitor said varying output
signals from said accelerometer;
c. a compass module electrically connected to said microprocessor
and configured to detect a magnetic orientation of said vehicle
and transmit to said microprocessor an output signal corresponding
to said magnetic orientation;
d. a radio frequency transceiver electrically connected to said
microprocessor, said transceiver designed to transmit radio
frequency signals to a second transceiver of a second braking
warning system, said transmitted radio frequency signals
corresponding to said deceleration forces exerted on said vehicle
and corresponding to said magnetic orientation of said first
vehicle;
e. said radio frequency transceiver further designed to receive
radio frequency signals from a remote transmitter capable of
sending messages understood by said warning system, said messages
corresponding to messages selected from presence, location, and
type of hazardous situation;
f. an alerting device electrically connected to said
microprocessor, said alerting device configured to transmit visual
or auditory alerts within said vehicle upon activation by said
microprocessor; and
g. said microprocessor is further programmed to ignore said
received signals from said transceiver when said first vehicle is
traveling at a deceleration rate corresponding to a pre-programmed
deceleration rate value.
5. The system of claim 4, wherein said remote transmitter is
installed on a non-motorized vehicle.
6. The system of claim 5, wherein said non-motorized vehicle is
selected from the group of bicycles, tricycles, scooters,
skateboards, skates, wagons, and ride-on toys.
7. The system of claim 4, wherein said remote transmitter is
installed at or near a potentially hazardous area.
8. The system of claim 7, wherein said area is selected from the
group of on-road construction sites, off-road constructions sites,
school zones, hospital zones, and accident sites.
9. The system of claim 4, wherein said remote transmitter is
installed on an emergency vehicle.
10. The system of claim 4, wherein said alerts generated
correspond to a type of potential hazard where or near where said
remote transmitter is installed. .
.. in accordance with the invention for the purpose of
illustrating the manner in which the invention may be used to
advantage, it will be appreciated that the invention is not
limited thereto. Accordingly, any and all modifications,
variations or equivalent arrangements which may occur to those
skilled in the art should be considered to be within the scope of
the invention as defined in ALL OF THE annexed claims...
