First Claim
Patent Images
1. A system for protecting children or infants from being left in a vehicle comprising:
- a safety seat in which a RFID tag is embedded, “
wherein the RFID tag is coupled to a sensor that detects whether a child is buckled into the safety seat”
;
a RFID tag reader operatively mounted in the cabin of said vehicle;
a computer;
a computer readable program installed on said computer, said computer readable program including;
a first instruction module being responsive to first signals from sensors to activate the RFID tag reader;
a second instruction module being responsive to second signals from the RFID tag that indicate that a child is buckled into the safety seat to wait a predetermined amount of time and, after passage of the predetermined amount of time, re-activate the RFID tag reader; and
a third instruction module being responsive to third signals from the RFID tag that indicate that the child remains buckled into the safety seat to sound alarms indicating the child is left in vehicle and taking other actions to prevent injury to the child.

Abstract
A wireless system that detects the presence of a child in a safety seat located in the passenger cabin of a vehicle includes a controller responsive to signals generated by sensors monitoring predefined functions of the vehicle, RFID tag device attached to the safety seat and RFID tag reader mounted in the cabin. The system generates control signals which activate an alarm, open the doors of the vehicle and roll down windows if the child is left in the safety seat of an unattended vehicle.

2. An apparatus, comprising:
-
a main control unit that emits a first enabling signal upon receipt of an indication that an ignition of an automobile has been turned off; a RFID reader that receives the first enabling signal from the main control unit and generates and forwards first electromagnetic waves in response to receiving the first enabling signal; an RFID tag coupled to a child safety seat that is configured to receive electromagnetic waves when a sensor detects that a buckle of the child safety seat is latched, such that when the buckle is latched and the RFID tag receives the first electromagnetic signals the RFID tag emits first identification signals, and wherein; the RFID reader receives the first identification signals and in response thereto forwards a first indication to the main control unit that a child is retained in the child safety seat; in response to receiving the first indication, the main control unit waits a predetermined amount of time and transmits a second enabling signal to the RFID reader; in response to receiving the second enabling signal, the RFID reader generates and forwards second electromagnetic signals; if the buckle remains latched, the REID tag emits second identification signals; the RFID reader receives the second identification signals and in response thereto forwards a second indication to the main control unit that a child is retained in the child safety seat; and the main control unit initiates an alarm to indicate that the child is retained in the child safety seat in response to receiving both the first and the second indications. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
