Warning system for detecting presence of a child in an infant seat
First Claim
1. A warning system for detecting presence of a child in an infant seat for reminding the driver to remove the child from the infant car seat when exiting the vehicle, comprising:
- means for providing a base for components to be connected;
means for providing voltage to circuit, removably connected to said means for providing a base for components to be connected;
means for detecting the presence of an occupant within the infant seat, electrically connected to said means for providing voltage to circuit;
means for detecting the “
on”
or “
off”
state of the vehicles dome light, electrically connected to said means for detecting the presence of an occupant within the infant seat;
means for generating an audible alarm in response to the alarm signal, electrically connected to said means for detecting the “
on”
or “
off”
state of the vehicles dome light, and rigidly connected to said means for providing a base for components to be connected;
means for providing a 7 second on and a 3 second off duration for the audible alarm cycle, rigidly connected to said means for generating an audible alarm in response to the alarm signal, and rigidly connected to said means for providing a base for components to be connected;
means for determining the on off duration length during alarm generation, rigidly connected to said means for providing a 7 second on and a 3 second off duration for the audible alarm cycle, rigidly connected to said means for providing voltage to circuit, and rigidly connected to said means for providing a base for components to be connected; and
means for smoothing out any voltage spikes within the circuit, rigidly connected to said means for providing a base for components to be connected.

Abstract
An apparatus is provided for warning when a child has been left in an infant car seat within a vehicle and the vehicle'"'"'s door is opened to accommodate exiting driver. The apparatus includes an occupant detection mechanism for detecting the presence of an occupant within an infant seat located within a vehicle; a light detection component for detecting the state of the vehicle'"'"'s dome light; a battery which provides power to the apparatus; an alarm which activates when the occupant detection mechanism detects the presence of an occupant within the infant seat and the light detection component detects the vehicles dome light has gone from an “off” state to an “on” state because the driver opened the door to exit vehicle. Components of the apparatus are located within the infant seat and can move from vehicle to vehicle along with the infant seat or from infant seat to infant seat.

10. A warning system for detecting presence of a child in an infant seat for reminding the driver to remove the child from the infant car seat when exiting the vehicle, comprising:
-
a circuit board, for providing a base for components to be connected;
a 9 volt battery, for providing voltage to circuit, removably connected to said circuit board;
a pressure switch, for detecting the presence of an occupant within the infant seat, electrically connected to said 9 volt battery;
a photo cell light detector, for detecting the “
on”
or “
off”
state of the vehicles dome light, electrically connected to said pressure switch;
a buzzer, for generating an audible alarm in response to the alarm signal, electrically connected to said photo cell light detector, and rigidly connected to said circuit board;
a 555 timer, for providing a 7 second on and a 3 second off duration for the audible alarm cycle, rigidly connected to said Buzzer, and rigidly connected to said circuit board;
a 47 k ohm resistor, for determining the on off duration length during alarm generation, rigidly connected to said 555 timer, rigidly connected to said 9 volt battery, and rigidly connected to said circuit board; and
a 100 uf capacitor, for smoothing out any voltage spikes within the circuit, rigidly connected to said circuit board.
