Child detector and reminder system
First Claim
1. A safety system that is adapted to remind a driver that a child is still in a car, and when necessary, alerts members of a public that the child has been left unattended inside the car, the system comprising:
- a first circuit that indicates when a buckle of the child'"'"'s seatbelt is buckled;
a second circuit that indicates when a buckle of the driver'"'"'s seatbelt is buckled;
a logic circuit that receives inputs from the first and second circuits, wherein, upon receipt of a specific series of inputs from the first and second circuits, the logic circuit produces a reminder output;
a first alarm that receives the reminder output from the logic circuit, and in response creates a first audible sound that is able to be heard inside the car;
a delay circuit that also receives the reminder output from the logic circuit and, after a set amount of time, produces a public alarm output; and
, a second alarm that receives the public alarm output from the delay circuit, and in response creates a second audible sound that is able to be heard outside of the car, wherein the second alarm is intended to attract members of the public.

Abstract
A safety system that reminds parents when their children are still strapped inside the car. The preferred system monitors the status of the driver'"'"'s seatbelt buckle and the child'"'"'s buckle, and includes at least two different alarms. The first alarm, which is not offending and can only be heard inside the Vehicle, is sounded after the driver unbuckles and the child remains buckled in the car. The second alarm, which is louder than the first and can be heard outside the vehicle, is sounded after a set amount of time has expired since the driver unbuckled, and yet the child remains buckled in the car. The second alarm is intended to draw the attention of members of the public, and on a hot day could save the child'"'"'s life.

11. A detection and reminder system that is adapted form attachment to a car, the system being able to remind a driver that a child is still in the car, and when necessary, alert members of a public that the child has been left unattended inside the car, the system comprising:
-
a first circuit that outputs a high signal when a buckle of the child'"'"'s seatbelt is buckled; a second circuit that monitors a status of the driver; a logic circuit that receives the outputs from the first and second circuits, wherein, upon receipt of a specific series of outputs from the first and second circuits, the logic circuit produces a reminder signal; a first alarm that receives the reminder signal from the logic circuit, and in response creates a first audible sound that is able to be heard inside the car; a delay circuit that also receives the reminder signal from the logic circuit and, after a set amount of time, produces a public alarm signal; and
, a second alarm that receives the public alarm signal from the delay circuit, and in response creates a second audible sound that is able to be heard outside of the car, wherein the second alarm is intended to attract members of the public. - View Dependent Claims (12, 13, 14, 15, 16, 17)
